Description

A kind of rapid cooling method of can/bottle beverage rapid cooling machine

technical field

The invention relates to the field of rapid cooling of can/bottle drinks, in particular to a quick cooling method of a can/bottle drink quick cooler.

Background technique

In the catering, retail and entertainment sectors, various forms of devices are used to keep products cool. For cold beverages, these devices form two typical groups - commercial beverage refrigerators and cold beverage vending machines. Both types of units are essentially refrigerators with large glass fronts, with hinged or sliding doors in the case of the first group (for manual dispensing) and dispensing mechanisms in the case of the second group. They pre-chill and store beverages for sale. In many cases, beverages are kept cold for long periods of time before they are finally sold. Then, a considerable amount of energy is used, which may be unnecessary. In order to prevent people from buying without cooling beverages, there are usually a large amount of cooling beverages in refrigerators or vending machines, and the refrigeration system needs to run for a long time to keep the beverages at a low temperature.

To summarize the problem, both types of devices operate inefficiently. In use, the first set of beverage refrigerators experienced a significant loss of cold air every time the doors were opened. Vending machines must provide the user with easy access to the vending trays where items are collected, resulting in a poor seal. Refrigeration systems often require background cycles to maintain efficiency, but this uses additional energy that is not directly used to cool the contents. Various beverage vending machines are also known that store beverages in an open-front refrigerator compartment for easy access and viewing of the product. These compartments obviously have an even greater waste of energy.

The end result is a high waste of electrical energy used to keep beverages cold for long periods of time ready for sale, regardless of when they may be sold. Energy waste isn't limited to hospitality vending machines at corporate venues. Beverage cooling compartments are also available at various small corner stores, petrol stations and coffee shop outlets. For these operators, the cost of electrical energy will account for a high proportion of their operating expenses. Energy waste isn't the only problem. Due to the heat generated by the refrigeration system, usually the waste heat energy by-products from the refrigeration system can cause unwanted warming of the localized area around the machine. This creates the embarrassment for the user of having to drink their satisfactorily cold beverage in an unsatisfactory warm zone.

Cooling speed is also an issue, especially in venues with high volume of beverage sales, such as at special events - concerts, sporting events, etc. Usually, at the start of the event, the drinks are sufficiently chilled as they have been refrigerated for several hours. However, once the event is under way, the volume of beverages being sold exceeds the capacity of the refrigerator to cool more beverages. The beverage is then sold only partially chilled or not chilled at all.

With the improvement of people's living standards, people's pursuit of quality of life is getting higher and higher, especially young people, they are more willing to drink cold drinks, and it takes more than ten minutes or even to put the drinks directly into the refrigerator to cool from room temperature to a suitable low temperature for drinking. Longer time, such a long time, does not meet the current high-efficiency life rhythm, and people's requirements for cooling speed are getting higher and higher, especially when people urgently need to drink low-temperature drinks, conventional cooling methods are not suitable. apply again.

Detailed ways

The rapid cooling method of a can/bottle drink quick cooling machine according to the present invention, put the can/bottle drink into the low-temperature cooling liquid, contact the cooling liquid to exchange heat, cool the can/bottle drink, and control the can/bottle drink The beverage in the bottle and the cooling liquid move relative to each other in the vertical direction, so that the beverage in the can/bottle is located above or below the liquid surface of the cooling liquid, and when it is above the liquid surface of the cooling liquid, put the beverage in the can/bottle and take out; when it is below the liquid level of the cooling liquid, the can/bottle drink is cooled, and the relative movement of the can/bottle drink and the cooling liquid in the horizontal direction is controlled, so that the can/bottle drink contacts the cooling liquid at different positions at different times and can be replaced quickly hot.

As shown in Figure 3, the specific steps are as follows:

1) Put the can/bottle drink into the quick cooler, control the movement of the grabbing device carrying the can/bottle drink and/or the cooling container containing the cooling liquid, so that the can/bottle drink and the cooling liquid are vertically opposite Approach until the drink in the can/bottle is below the liquid level of the cooling liquid, and the drink in the can/bottle is in contact with the cooling liquid to exchange heat;

2) Control the rotation of the grabbing device carrying the can/bottle drink and/or the cooling container containing the cooling liquid, so that the can/bottle drink and the cooling liquid move relative to each other in the horizontal direction, and the can/bottle drink contacts different locations at different times for cooling Liquid rapid heat exchange;

3) After the cooling is completed, control the movement of the grasping device carrying the can/bottle drink and/or the cooling container containing the cooling liquid, so that the can/bottle drink and the cooling liquid are relatively far apart in the vertical direction until the can/bottle drink is located Above the liquid level of the cooling liquid, the cooled can/bottle drink is sent out.

The relative movement in the vertical direction is to control one of the grasping device carrying the can/bottle drink and the cooling container containing the cooling liquid to move in the vertical direction, while the other does not move; or to control the grasping of the can/bottle drink The extraction device and the cooling container containing the cooling liquid move at the same time: in the opposite direction or in the same direction at different speeds, so that the drink in the can/bottle is located above or below the liquid level of the cooling liquid.

The relative movement in the horizontal direction is to control one of the grasping device carrying the can/bottle drink and the cooling container containing the cooling liquid to rotate around the axis of the quick cooler, while the other does not move; or to control the movement of the can/bottle drink The grabbing device and the cooling container containing the cooling liquid rotate at the same time: reverse or in the same direction at different speeds. The relative movement in the horizontal direction also includes the rotation of the can/bottle beverage around its own axis.

The above-mentioned situations of relative movement in the vertical direction and relative movement in the horizontal direction can be combined arbitrarily.

As an optional implementation, the cooling container can be fixed, and the lifting of the grasping device can be controlled to move the can/bottle beverage between the liquid level and the lower position of the cooling liquid, and the rotation of the grasping device can be controlled , so that the cans/bottles are in contact with different cooling liquids at different times to increase convective heat transfer.

In yet another optional implementation, the up and down direction of the grabbing device can be set to be stationary, and the lifting of the cooling container can be controlled so that the can/bottle drink can move between the liquid surface and the lower position of the cooling liquid, and the cooling container can be controlled to move up and down. The rotation of the tank/bottle makes the drink in the can/bottle contact with different cooling liquids at different times, increasing convective heat transfer.

In terms of relative movement in the vertical direction, simultaneous relative movement of the grabbing device and the cooling container is the optimal solution. At the same speed, the relative movement of the two devices can save half the time, thereby shortening the waiting time for users. But in practice, since the inside of the cooling container is equipped with cooling liquid, the upper opening of the cooling container is used for can/bottle drinks to enter, and the cooling container is also equipped with a cooling system for cooling liquid, so the cooling liquid is easy to spill out when rotating or moving or it needs to be combined with It is inconvenient for the refrigeration system to rotate or move together, so the cooling container is fixed in most cases.

As shown in Figure 4, after putting in the can/bottle drink, control the cooling container to stay still in the vertical direction, and control the grasping device carrying the can/bottle drink to move close to the cooling container along the axis of the cooling container, and the can/bottle The body drink enters below the liquid level of the cooling liquid. After cooling, the grasping device that controls the holding can/bottle drink moves along the axis of the cooling container away from the cooling container, and the can/bottle drink returns to above the cooling liquid level.

After the can/bottle drink enters below the liquid level of the cooling liquid, control the cooling container not to rotate, control the can/bottle drink to rotate around its own axis to form a self-rotation, and at the same time control the can/bottle drink to revolve around the axis of the cooling container or grabbing device The rotation of the shaft center forms a revolution, the revolution speed is 100-1000rpm, the rotation speed is 50-500rpm, and the direction of revolution and rotation is opposite.

In the above cooling process, only when the can/bottle drink is put in and taken out, the can/bottle drink is above the liquid level of the cooling liquid, and the rest of the time the can/bottle drink is under the cooling liquid.

In the method for rapidly cooling beverages according to the present invention, as shown in Figures 1 and 2, the beverage rapid cooling machine includes: a cooling container 1 for containing cooling liquid, a grasping device 9 for carrying a tank/bottle drink, and a grasping device 9 Located above the cooling container 1 , the rapid cooling machine is provided with an inlet and outlet for the can/bottle drink 10 . Control the relative movement of the grasping device 9 and the cooling container 10, so that the can/bottle beverage 10 moves between the liquid surface and the lower position of the cooling liquid. When it is above the liquid surface, the can/bottle beverage is picked and placed. When the liquid level is below, the can/bottle drink is cooled, and the grasping device and the cooling container are controlled to rotate relative to each other, so that the can/bottle drink is in contact with different cooling liquids at different times to increase convective heat transfer.

The specific steps are: when quickly cooling cans/bottles of beverages, place the cans/bottles of beverages into the input port of the rapid cooling machine;

The grabbing device 9 grabs the tank body, and puts the tank body into the cooling liquid of the cooling container from top to bottom until the tank body is completely immersed in the cooling liquid;

Control the rotation of the tank in the cooling liquid and exchange heat with the cooling liquid;

After the beverage in the tank drops to the set temperature, control the upward movement of the tank body, return to above the liquid level of the cooling liquid, and send the beverage in the tank/bottle to the outlet.

When the above-mentioned can/bottle drink needs to be refrigerated, it is immersed in the cooling liquid. After the cooling is completed, it rises above the liquid level of the cooling liquid. reuse.

Among them, after the can/bottle drink is placed in the input port, the can/bottle drink is moved to the inside of the quick cooler through a horizontally movable or rotating transfer platform, and sent to the right below the grabbing device, and the grabbing device is downward Move to the corresponding position, after grabbing the can/bottle drink, the grabbing device moves down together with the can/bottle drink; the drink in the tank drops to the set temperature, returns to above the cooling liquid level, and passes through a horizontally movable Or the rotating transfer platform moves the can/bottle drink to the outlet.

The drink in the can/bottle moves down to below the liquid level of the cooling liquid, and the drink in the can/bottle is controlled to rotate around at least two axes. / The beverage in the bottle rotates around the axis of the cooling container or the axis of the grasping device to form a revolution.

Convective heat transfer is largely governed by the fluid flow regime within the boundary layer. Increasing the velocity gradient within the boundary layer will increase convective heat transfer. Although the Reynolds number is the main parameter controlling whether the boundary layer is laminar or turbulent, it can be switched due to surface texture or roughness and local pressure gradients. The more complex movement of the vessel and cooling liquid provided by this arrangement gives more degrees of freedom to control the thickness and velocity gradients within the boundary layer. This allows the device to maximize convective heat transfer while eliminating semi-melting or ice formation that has hindered attempts to achieve rapid cooling in the past.

The rotational speed of the revolution is 100-1000rpm, the rotational speed of the autorotation is 50-500rpm, and the directions of the revolution and the rotation are opposite. This maximizes convective heat transfer.

Whether the beverage in the tank has dropped to the set temperature can be judged by detecting the time when the can/bottle drink is immersed in the cooling liquid. . Experiments can be done in advance to obtain the relationship between the time and temperature when the can/bottle drink is immersed in the cooling liquid and rotates in the cooling liquid, so as to obtain the time for the can/bottle drink to immerse in the cooling liquid when it reaches the set temperature, so when the can/bottle drink reaches the set temperature When the time that the body is immersed in the cooling liquid reaches the set value, it can be proved that the drink in the can/bottle body has dropped to the set temperature, and the difference will not be too large.

The input port and the take-out port are arranged on both sides of the quick-cooler, and the user puts the can/bottle drink in and moves to the take-out port on the other side of the quick-cooler, and takes out the cooled can from the input port after the time is up. / bottle of drink. This situation is applicable to when many users need to queue up, and the user leaves from the other direction after taking the drink, so that there will be no collision with the next user, and the order is in good order.

The inlet and outlet may also be the same opening. The user can wait in place after putting in the can/bottle drink, and take out the cooled can/bottle drink from the input port when the time is up. This situation is used when the quick cooler is set at the corner or the end of the road, or it is suitable for the situation where the user does not often concentrate.

The quick cooler is provided with a closed shell, inside the shell is set the above-mentioned cooling container for containing the cooling liquid, the grabbing device for grabbing the can/bottle drink, the lifting device for controlling the movement of the grabbing device, and the device for controlling the rotation of the grabbing device. The rotating device and the grabbing device are located on the top of the cooling container. The shell is provided with the inlet and outlet of the can/bottle drink. The height of the inlet and the outlet is in line with the most comfortable height for the human body, such as: 1.1-1.3 meters Between, it can also be set to a height suitable for adults and a height suitable for children according to different places of use

The cooling liquid is water, and the temperature of the cooling liquid is controlled to be lower than or equal to the set temperature of the cooling tank/bottle drink. Preferably, the temperature of the cooling liquid is maintained at -1°C to +1°C. The cooling liquid is a saline solution whose temperature can drop to minus ten degrees. After the can/bottle drink is quickly cooled from the solution, some solution will stick to the tank. When the user drinks the drink, he will feel it sticking to the tank. The salty taste of the brine solution will affect the drinking effect of the beverage, so it is best to use water as the cooling liquid, which is colorless and tasteless, preferably pure water, which will not affect the drinking effect and will not affect human health. The lowest temperature of water is 0°, and it will freeze when it is lower than 0°, and the best drinking temperature of most beverages is above 0°, such as: the best drinking temperature of cola is 2.2°, the best drinking temperature of beer The best drinking temperature is 8°. Therefore, using water as a cooling liquid can meet the cooling temperature requirements of most beverages.

Embodiment one

In this embodiment, on the basis of the above, multiple cans/bottles of beverages can be cooled at the same time for each rapid cooling: multiple cans/bottles of beverages are placed in the input port of the rapid cooling machine in sequence;

After the grabbing device grabs the tanks sequentially, it simultaneously puts multiple tanks into the cooling liquid of the cooling container from top to bottom until multiple tanks are completely immersed in the cooling liquid; s

Control the rotation of the tank in the cooling liquid and exchange heat with the cooling liquid;

After the drinks in cans/bottles drop to the set temperature, the cans are controlled to move upwards and return to above the liquid level of the cooling liquid, and the drinks in multiple cans/bottles are sent to the outlet in sequence.

This situation is suitable for when multiple people need to cool drinks, multiple cans/bottles of drinks can be put into the quick cooling machine in sequence, and taken out in sequence after the quick cooling is completed.

Embodiment two

As shown in Figure 5, if the user only needs to cool one or two beverages, in order to reduce the cooling time of a single can/bottle, N cans/bottles are pre-stored in the quick cooler, and the user needs to cool the can/bottle When drinking, put a can/bottle of drink into the quick cooler;

Pre-store N cans/bottles of beverages in the quick cooler, and control the movement of the grabbing device carrying the cans/bottles and/or the cooling container carrying the cooling liquid, so that the cans/bottles and the cooling liquid are relatively close to each other in the vertical direction , the newly placed can/bottle drink and N pre-stored can/bottle drinks are immersed in the cooling liquid to cool down;

After the cooling is completed, control the movement of the grasping device carrying the can/bottle drink and/or the cooling container carrying the cooling liquid, so that the can/bottle drink and the cooling liquid are relatively far away in the vertical direction until the can/bottle drink is in the cooling position. Above the liquid level, send out one of the N pre-stored cans/bottles whose temperature is lower than the current temperature of the cans/bottles just put in, preferably the N pre-stored The can/bottle drink with the lowest temperature among the can/bottle drinks is sent out, and the put in can/bottle drink is pre-stored in the quick cooler.

Preferably, N cans/bottles with a certain temperature gradient are pre-stored in the quick cooler. When the user needs to cool the cans/bottles, he puts a normal temperature can/bottle into the quick cooler. The normal temperature tank/bottle The bottle drink and N pre-stored cans/bottles are immersed in the cooling liquid to cool down until the lowest temperature among the original N pre-stored cans/bottles reaches the set temperature, and the can/bottle will reach the set temperature. Bottled drinks are sent out of the quick cooler, and the input cans/bottles are pre-stored in the quick cooler.

The time required for the coldest one of the original N pre-stored cans/bottles to reach the set cooling temperature is less than or equal to T1/(N+1), and each time the cans/bottles just put in are mixed with N The time for two pre-stored cans/bottles to be immersed in the cooling liquid to cool down is T1/(N+1), and T1 is the time for the normal temperature cans/bottles to be placed in the cooling liquid and rotate to drop to the set temperature.

When there are continuous users cooling cans/bottles, the time for each user to wait for the quick cooling of cans/bottles is T1/(N+1), and the temperature of the pre-stored N cans/bottles is between room temperature and set Between the temperatures, there is a uniform temperature gradient, and the temperature is an arithmetic progression. The time for normal temperature cans/bottles and N pre-stored cans/bottles to be immersed in the cooling liquid is T1/(N+1), and the time for users to quickly cool each can/bottle is T1/(N+ 1). This greatly saves the user's waiting time.

If the user puts a can/bottle drink into the quick cooler, and the temperature of at least one can/bottle drink among the N cans/bottles has reached the set cooling temperature, there is no need to put the can/bottle The beverage in the bottle is immersed in the cooling liquid together with the N pre-stored beverages in the can/bottle, and the beverage in the can/bottle that reaches the set cooling temperature is directly sent out.

There are (N+1) grippers on the grabbing device, N is a positive integer, and one gripper is empty in the initial state;

Place the can/bottle drink into the inlet of the quick cooler;

Grab the tank with the empty gripper, put the tank into the cooling liquid of the cooling container from top to bottom, until the tank is completely immersed in the cooling liquid, and control the rotation of the tank/bottle beverage around the axis of the respective tank to form a rotation. At the same time, it rotates around the axis of the cooling container or the axis of the grabbing device to form a revolution, and exchanges heat with the cooling liquid;

After T1/(N+1) time, control the upward movement of the tank body, return to above the liquid level of the cooling liquid, and send the drink in the tank/bottle facing the outlet to the outlet.

As shown in Figure 6, in order to ensure that the coldest one among the original N pre-stored cans/bottles reaches the set temperature and then is sent out of the quick-cooler, the internal pre-stored N cans can be controlled by controlling the rotation angle of the grasping device. The temperature of the can/bottle drink is between normal temperature and the set temperature, with a uniform temperature gradient. After each quick cooling, the lowest temperature among the N cans/bottle drinks is facing the outlet. During the quick cooling process Among them, the angle at which the grabbing device rotates around its center is (M*360°+360°/(N+1)+X°), where T1 is when the normal temperature can/bottle is placed in the cooling liquid and rotated to the set point. The time to set the temperature, X° is the angle from the inlet to the outlet, and M is an integer;

The empty gripper rotates to the input port, ready to grab the next can/bottle drink to be cooled, and the cycle is repeated in turn. The user waits for each can/bottle drink to cool down for T1/(N+1).

Specifically, each time the empty gripper grabs the can body, it rotates 360°/(N+1) above the coolant level, and the can/bottle drink at a position on the empty gripper is facing the input port, and then puts all the cans /The drink in the bottle moves below the liquid level of the cooling liquid, and the rotation angle is M*360°. After the time is up, move to above the liquid level of the cooling liquid, and rotate X°. The can/bottle drink in the previous position of the empty gripper is facing Take out the outlet.

When the inlet and outlet are the same opening, the X° is 0°.

In the above method, when there are continuous users waiting to cool the cans/bottles, the temperature of the N pre-stored cans/bottles is between the normal temperature and the set temperature, with a uniform temperature gradient. If there is no user for a long time to cool the cans /bottle beverages, the N cans/bottle beverages stored in the interior will reach a temperature close to that of the cooling liquid, and at this time, N cooled beverages can be exchanged at one time.

In the above-mentioned rapid cooling process, only the user puts in the can/bottle drink, and the grabbing device moves to the upper part to grab the can/bottle drink, and the can/bottle drink is immersed in the cooling liquid at other times.

As shown in Figure 7, in order to ensure that the lowest temperature among the original N pre-stored cans/bottles reaches the set temperature and then is sent out of the quick-cooler, the time for each can/bottle to enter the quick-cooler can be detected To control the one with the lowest temperature among the N cans/bottles of beverages facing the outlet after each rapid cooling.

Set the timer to detect the time when each can/bottle drink is put into the quick-cooler, and start counting when the can/bottle drink is put in, and transmit the detected time to the control system of the quick-cooler, every time there is a new can/bottle After putting in the body drink, the control system controls the can/bottle drink with the longest cooling time among the pre-stored N cans/bottles to be sent out after the rapid cooling time T, and the timer is reset.

Preferably, a timer is arranged on each gripper and is connected to the main control board 6. The gripper starts timing after grabbing the can/bottle drink, and the timing is reset to zero after the gripper is released.

Embodiment three

Because the can/bottle drink needs to be immersed in the cooling liquid for cooling, the cooling liquid will be polluted after a long time. On the one hand, if the cooling liquid on the tank is drunk, it will affect health. In order to solve the above-mentioned problems caused by the user's bad feeling, during the rapid cooling process, the cooling liquid in the cooling container is purified from time to time or intermittently, so as to realize the recycling of the cooling liquid.

The purification process is to extract the cooling liquid from the cooling container, and then carry out the coarse filtration process of the coarse filter, the adsorption process of the activated carbon, and the fine filtration process of the fine filter, and then return the cooling liquid to the cooling container. After treatment, the coolant can be recycled.

In the rapid cooling process, the turbidity of the cooling liquid is detected, and when the turbidity of the cooling liquid exceeds the set value, the cooling liquid is purified to realize the recycling of the cooling liquid, or in the above rapid cooling process, the cooling liquid is periodically The liquid is purified to realize the recycling of the cooling liquid.

Specifically, a turbidity sensor is set in the cooling container to detect the turbidity of the cooling liquid. The turbidity sensor is connected with the control system of the quick cooler and transmits the detected turbidity to the control system. When the cooling liquid detected by the turbidity sensor When the turbidity exceeds the set value, the control system controls the purification of the cooling liquid, and then returns to the cooling container from the upper part for reuse.

Or set a timer in the quick cooler to detect the time, and at regular intervals, the control system controls the cooling liquid to be extracted from the bottom of the cooling container, purified, and then returned to the cooling container from the upper part for reuse.

If it is detected that the turbidity inside the cooling container exceeds another set value, a signal is sent to the control system, and the control system sends an alarm for replacing the cooling liquid or the control system controls the replacement of the cooling liquid.

Embodiment four

After cooling, the surface of the can is covered with many cooling liquid droplets, and the surface of the cooled can/bottle drink is wet when the user takes it. The beverage in the bottle rotates at a high speed to separate the cooling liquid droplets sticking to the peripheral wall of the can/bottle beverage from the peripheral wall of the tank/bottle, that is, to shake off the cooling liquid droplets brought out.

The high-speed rotation of the can/bottle beverage is to control the high-speed rotation of the can/bottle beverage around its own axis and/or the high-speed rotation around an axis parallel to and not coincident with its own axis. Only the can/bottle drink that is about to be taken out can be controlled to rotate around its own axis at high speed. Avoid doing useless work.

While controlling the upward movement of the can/bottle drink, the can/bottle drink can be controlled to rotate around its axis at high speed to shake off the cooling liquid droplets brought out.

It is also possible to control the can/bottle beverage to move upwards to the position of the outlet and then stop the upward movement. At this time, the can/bottle beverage is controlled to rotate at a high speed around its axis to throw off the cooling liquid droplets brought out.

The rotational speed of the high-speed rotation is 50-800 rpm, preferably 200-500 rpm. If the speed is too small, some small droplets will not be thrown off; if the speed is too high, the machine will be unstable.

The time of the high-speed rotation is 3-10s, preferably 4-8s. Too short a time and the coolant droplets cannot be completely separated, too long a waste of time and wasted power.

After the grabbing device grabs the drink in the can/bottle, it covers the upper part of the tank, isolates the recessed space formed by the upper flange of the tank from the cooling liquid, and prevents the cooling liquid from entering the recessed space formed by the upper flange of the tank. Avoid getting coolant in the sunken space above the tank, wetting the user's clothes or wetting the ground.

Embodiment five

The method for maintaining the constant temperature of the cooling liquid described in this embodiment, the cavity of the cooling container 1 is equipped with a cooling liquid 3, the cooling container is provided with a refrigeration system, the cooling liquid contains at least part of water, and the method for maintaining the constant temperature of the cooling liquid is: The refrigeration system is started, and the cooling liquid in it is refrigerated through the container wall of the cooling container, so that the temperature of the cooling liquid drops to near the freezing point, and the surrounding wall of the cooling container begins to freeze;

As the refrigeration progresses, the peripheral wall of the cooling container gradually forms an ice layer 2; when the thickness of the ice layer increases to a certain value, the refrigeration system stops refrigeration;

The ice layer melts gradually, so that the cooling liquid and the ice layer maintain a temperature close to the freezing point in the cooling container;

When the ice layer is reduced to a certain thickness, start the refrigeration system again;

Circulate in turn to keep the coolant temperature at a temperature near the freezing point.

The ice layer thickness on the inner peripheral wall of the cooling container is directly detected by the ice layer thickness sensor 4 . The ice layer thickness sensor 4 is connected with the main control board 6 of the quick cooler. During cooling, when there is an ice layer on the inner peripheral wall of the cooling container, the ice layer thickness sensor detects the thickness of the ice layer. When the ice layer thickness reaches or exceeds the maximum set value, the refrigerating The system stops cooling; after stopping cooling, when the ice layer thickness sensor detects that the ice layer thickness reaches or falls below the minimum set value, the cooling system starts cooling.

During the cooling process of the cooling liquid, the maximum set value and the minimum set value of the thickness of the ice layer correspond to the width or diameter of the cooling container. The maximum set value and the minimum set value of the ice layer thickness are proportional to the width or diameter of the cooling container, and the maximum set value of the ice layer thickness is 1/50~1/10 of the width or diameter of the cooling container Within the range, the minimum set value of the thickness of the ice layer is within the range of 1/80~1/50 of the width or diameter of the cooling container.

During the cooling process of the coolant, when the thickness of the ice layer increases to 20-30 mm, the refrigeration system stops cooling, and when the thickness of the ice layer decreases to 15-20 mm, the refrigeration system restarts refrigeration. The thickness of the ice layer is related to the volume of the cooling container.

The temperature of the cooling liquid in the cooling container is detected by the temperature sensor, the time is detected by the timer, and the thickness of the ice layer is judged by detecting the time when the temperature of the cooling liquid drops to freezing point. A temperature sensor can be installed in the cooling container. When cooling, the temperature of the cooling liquid will gradually decrease. After the temperature sensor detects that the cooling solution has dropped to freezing point, the timer will start counting. After the set time T1 is reached, the thickness of the ice layer will reach or exceed the maximum set Set value, the refrigeration system stops refrigeration; after the refrigeration is stopped, the temperature of the cooling liquid is maintained near the freezing point for a certain period of time. After the temperature sensor detects that the cooling solution has risen above the freezing point, it starts timing. After the set time T2 is reached, the ice layer is completely melted , the refrigeration system starts refrigeration again.

During the cooling process of the cooling liquid, the set times T1 and T2 correspond to the width or diameter of the cooling container, and the set times T1 and T2 are proportional to the width or diameter of the cooling container.

The refrigeration system at least includes an evaporator pipeline 7 wound on the side wall of the cooling container. When the refrigeration system is started, the evaporator pipeline 7 absorbs heat, and the temperature of the cooling liquid drops. After dropping to freezing point, the evaporator pipeline 7 continues to absorb heat , the inside of the side wall of the cooling container begins to freeze. When cooling, the refrigeration system at least uniformly cools the surrounding wall of the cooling container.

The outer periphery of the cooling container and the evaporator pipeline 7 is provided with a cold storage structure, which absorbs part of the cold energy radiated by the cooling container and the refrigeration system through the cold storage structure. How often to start. The outer periphery of the cooling container and the evaporator pipeline 7 is provided with an insulating layer 8 to keep the inside warm.

The above description is only a preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, various modifications and improvements can be made, which should also be regarded as the present invention. protection scope of the invention.
