Description

A kind of refrigeration method of can/bottle body beverage

technical field

The invention relates to the field of rapid cooling of beverages in cans/bottles, in particular to a refrigeration method for beverages in cans/bottles.

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 users 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

A method for refrigerating can/bottle beverages according to the present invention, the can/bottle beverage is put into a low-temperature cooling liquid, contacts with the cooling liquid to exchange heat, cools the can/bottle beverage, and controls the temperature of the can/bottle beverage and The cooling liquid moves 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 the beverage in the can/bottle is put in and taken out when it is above the liquid surface of the cooling liquid; When the cooling liquid is below the liquid level, the can/bottle drink is cooled. If the temperature of the can/bottle drink is high, the relative movement of the can/bottle drink and the cooling liquid in the horizontal direction is controlled to make the can/bottle drink different The coolant in contact with different positions at all times exchanges heat quickly.

Refrigeration in the present invention refers to refrigeration in a broad sense, including processes such as quick cooling, cold storage, freezing, etc. for low-temperature treatment of items.

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, and the refrigerated can/bottle drink

Embodiment one

The cooling liquid contains at least part of water, and the cooling liquid is kept at a constant temperature by adopting the ice layer cold storage method.

As shown in Figure 2, the method of ice layer cold storage is:

The refrigeration system starts to refrigerate the peripheral wall of the cooling container containing the cooling liquid, so that the temperature of the cooling liquid drops to near the freezing point, and the inner peripheral wall of the cooling container begins to freeze;

As the refrigeration progresses, the surrounding wall of the cooling container gradually forms an ice layer. When the thickness of the ice layer increases to a certain thickness, the refrigeration system stops cooling, and the cooling liquid and ice layer maintain a temperature close to the freezing point in the cooling container;

As the can/bottle drink is cooled, the ice layer gradually melts, and when the ice layer is reduced to a certain thickness, the refrigeration system is started again; the cycle is repeated sequentially to keep the temperature of the cooling liquid at a temperature near the freezing point.

The coolant is used to cool items that need to be cooled, such as cans/bottles. If the temperature of the coolant is not fixed, the temperature to which the cans are cooled cannot be accurately controlled. Therefore, maintaining a constant temperature of the coolant is very important for the control of the cooling temperature. If the temperature sensor is simply set to detect the temperature of the coolant to control the start and stop of the refrigeration system, the refrigeration system needs to be started and stopped frequently, which seriously affects the service life of the refrigeration system. noise.

The present invention skillfully utilizes the principle that when the solid-liquid coexists, the heat energy absorbed or released is transformed into the internal energy, and the temperature is constant, and the cooling liquid can be controlled to maintain a constant temperature for a long time under the state of solid-liquid coexistence. The peripheral wall of the cooling container is uniformly refrigerated, so that the inner peripheral wall of the cooling container is frozen to form an ice layer, and the internal constant temperature liquid can be used as a cooling solution. The use of ice storage can reduce the start-stop frequency of the refrigeration system, prolong the service life of the refrigeration system, and reduce the frequency of noise.

At the same time, the start and stop frequency of the refrigeration system is reduced, and the number of starts and stops within a fixed time is reduced. The number of starts and stops of any electrical component within the service life is fixed, so the number of starts and stops within a fixed time is reduced, which can extend the refrigeration system. The life of the compressor, especially the compressor, when the compressor is started, there will be noise, and reducing the starting frequency of the compressor can also reduce noise pollution.

The method of controlling the start and stop of the refrigeration system: the ice layer thickness is directly detected by the ice layer thickness sensor. This method is also the most direct method. An ice layer thickness sensor is installed inside the cooling container to detect the ice layer thickness sensor. The ice layer thickness sensor can judge the thickness of the ice layer according to the different parameters such as resistance, capacitance, and conductivity in the process of water freezing and ice melting, or it can also use sensors such as laser ranging sensors or thickness sensors to detect the thickness of the ice layer.

When cooling, when there is an ice layer on the inner wall of the cooling container, the ice layer thickness sensor detects the thickness of the ice layer, and when the ice layer thickness reaches or exceeds the maximum set value, the refrigeration system stops cooling;

After stopping refrigeration, when the ice layer thickness sensor detects that the ice layer thickness reaches or is lower than the minimum set value, the refrigeration system starts refrigeration, and the maximum set value and the minimum set value of the ice layer thickness are related to the width or corresponding to the diameter.

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. When the cooling container is large, the maximum setting value and the minimum setting value of the ice layer thickness should be set relatively larger; when the cooling container is small, the maximum setting value and the minimum setting value of the ice layer thickness should be set relatively small , so as to ensure that the internal liquid absorbs heat when cooling the beverage in the tank with the cooling liquid. Before the temperature rises, it will be absorbed by the ice when it melts, and it will take a certain amount of time in the initial stage of refrigeration. The larger the cooling container, the more cooling capacity it needs The more and the longer the time, the remaining ice layer is required to maintain the constant temperature of the cooling liquid at this stage, so the maximum and minimum setting values of the thickness of the ice layer match the width or diameter of the cooling container.

Preferably, 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 1/50-1/50 of the width or diameter of the cooling container. Within the range of 10, the minimum set value of the ice layer thickness is within the range of 1/80-1/50 of the width or diameter of the cooling container.

There is also a method of controlling the start and stop of the refrigeration system: detecting the temperature of the cooling liquid in the cooling container through a temperature sensor, detecting the time through a timer, and judging the thickness of the ice layer by detecting the time when the temperature of the cooling liquid drops to freezing point.

When cooling, the temperature of the cooling liquid decreases gradually. After the temperature sensor detects that the cooling solution drops to freezing point, the timer starts counting. When the set time T1 is reached, the ice layer thickness reaches or exceeds the maximum set value, and the refrigeration system stops cooling;

After the cooling 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, the timing starts. After the set time T2 is reached, the ice layer is completely melted, and the refrigeration system starts cooling again. This method requires a larger power of the refrigeration system, and the extension time of the initial stage of refrigeration is shorter.

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.

When cooling, the refrigeration system at least uniformly cools the surrounding wall of the cooling container, and absorbs part of the cold energy radiated by the cooling container and the refrigeration system through a cold storage structure. When the ice layer melts or the temperature of the cooling liquid rises, this part of the cold energy is released, reducing the start-up of the refrigeration system. Frequency of. Maximize the utilization of cooling capacity and reduce the waste of cooling capacity. The outermost layer can also be provided with an insulating layer to block the influence of external temperature on the internal constant temperature.

Coolant 3 is housed in the cavity of cooling container 1 as shown in Figure 1, and cooling container is provided with refrigeration system, and described refrigeration system is compressor refrigeration system or other any refrigeration systems that can be refrigerated, and the evaporator tube of described refrigeration system The road 7 is evenly wound on the outer wall of the cooling container 1. The ice layer thickness sensor 4 or temperature sensor is arranged in the cooling container 1. The ice layer thickness sensor 4 or temperature sensor is connected to the main control board 6. The outermost layer of the cooling container 1 is preferably provided with The insulation layer 8 of the foam material, the cooling liquid 3 contains at least part of water, which can be water or aqueous solution, and the ice layer 2 on the inner wall of the cooling container 1 maintains the temperature of the internal cooling liquid near the freezing point.

The cooling liquid is water, maintained at 0°±1°. 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 two

The can/bottle comes out of the cooling liquid, and there are many cooling liquid droplets on the surface. When the user gets the cooled can/bottle drink, the surface of the drink is wet, and it is easy to wet the clothes and the floor. To solve the above problems, the can/bottle drink is Before taking out, control the drink in the can/bottle to move from below the liquid level of the cooling liquid to above the liquid level of the cooling liquid, control the high-speed rotation of the drink in the can/bottle, and separate the cooling liquid droplets sticking to the surrounding wall of the can/bottle with the can /The peripheral wall of the bottle body is separated, that is, the coolant droplets brought out are thrown off.

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.

During the refrigeration process, multiple cans/bottles can be refrigerated at the same time. When multiple cans/bottles are refrigerated at the same time, only the cans/bottles to be taken out are controlled to rotate at high speed around their own axis. Avoid doing useless work.

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

As shown in Figures 5 and 6, the structure for controlling the rotation of can/bottle beverages in the present invention includes a turntable 41, on which a plurality of grippers 44 are arranged, and the grippers grab the can/bottle beverage 45, and the turntable 41 The first motor 42 is set in the center, and the second motor 43 is set above the gripper 44. The rotation of the second motor 43 drives the rotation of the gripper 44 to drive the can/bottle drink 45 to rotate around its own axis, and the rotation of the first motor 42 drives the can/bottle Body drink 45 rotates around the axis of the turntable. The can/bottle drink is always grabbed by the gripper in the refrigerated cooling container, or the can/bottle drink is placed in the refrigerated cooling container, and when it needs to be taken out, it is taken out by the gripper. Before the can/bottle drink 45 is sent out of the refrigerating machine, a high-speed rotation process is added to separate the cooling liquid droplets attached to the can/bottle drink 45 .

After the above method, there are not too many cooling liquid droplets on the surface of the delivered can/bottle drink, and when the user takes it by hand, it will not feel too wet, and at the same time, it will not be carried out by the can/bottle drink. The coolant droplets wet the user's clothes or the ground.

Embodiment three

Because the can/bottle drink needs to be immersed in the cooling liquid, and the cooling liquid in the cold storage is recycled, 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. On the other hand, it will cause a bad feeling to the user visually. In order to solve the above problems, during the rapid cooling process, the cooling liquid in the cooling container is purified from time to time or intermittently to realize the recycling of the cooling liquid.

As shown in Figure 1, a circulation loop is set on the cooling container, and a coarse filtration module, an adsorption module, and a fine filtration module are arranged on the circulation loop. The coarse filtration module and the fine filtration module are filtered by a filter element, and the diameter of the filter element of the coarse filtration module is larger than that of the fine filtration module. The filter diameter of the filter element and the adsorption module adopts activated carbon adsorption.

The process of the purification treatment is to extract the cooling liquid out of the cooling container containing the cooling liquid through a circulation loop, and then carry out the coarse filtration treatment of the coarse filter, the adsorption treatment of activated carbon, the fine filtration treatment of the fine filter, and then pass through the The circulation loop returns the coolant to the cooling container.

During the refrigeration 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 the cooling liquid is regularly purified during the above-mentioned rapid cooling process , Realize the recycling of coolant.

The control method for detecting the turbidity of the cooling liquid is specifically: setting a turbidity sensor to detect the turbidity of the cooling liquid, and the turbidity sensor is connected with the control system of the quick cooler to transmit the detected turbidity to the control system, When the turbidity of the cooling liquid detected by the turbidity sensor exceeds the set value, the control system controls the purification of the cooling liquid, and then returns to the cooler from the upper part for reuse. This control method is the most accurate. When the turbidity of the internal cooling liquid exceeds the set value, the purification treatment process is started, and when the turbidity of the internal cooling liquid is low, the purification treatment process does not need to be started.

Periodic purification of the cooling liquid is as follows: a timer can be set in the cooling container to detect the time. At regular intervals, the control system controls the cooling liquid to be drawn out from the bottom of the cooling container through a circulation loop for purification, and then returns to the cooling container from the upper part. to be used again in the device. This kind of control method is the simplest, only needs to start the purification treatment at regular intervals.

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.

Through the above method, the cooling liquid can be guaranteed to be clean and hygienic. Even if the user drinks the cooling liquid droplets on the beverage can/bottle, it will not cause harm to the body. At the same time, the cooling liquid is clean and the user feels comfortable after looking at it. / Bottled beverages are placed in it to be refrigerated.

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.
