Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a food frying device, and in particular, oil heated by an external heating device is supplied into a frying pan, and an endless conveyor is passed through the oil. This invention relates to a device that controls the temperature distribution within the frying pan by supplying oil from the top or bottom of the food, or from both sides, when frying the food while it is being transported. .

Conventionally, this type of frying apparatus includes a device in which an endless conveyor passes through the oil in a frying pan, and the food is fried while being transferred by the conveyor.The oil is heated by heating the bottom of the frying pan with direct heat. There are direct-fire type and external heating type, in which oil heated externally is supplied to the frying pan via a pipe.

This invention is a frying device that belongs to the latter category, but conventionally it has a structure in which heated oil is supplied to the bottom of a frying pan (the bottom of the frying pan or a side surface near the bottom).

This is because the above-mentioned direct-fire heating heats from the bottom of the frying pan, so it seems that the heat source inside the frying pan is located at the bottom, following this example.

Also, when cleaning the inside of the frying pan, it was necessary to attach and detach the endless conveyor from the top of the frying pan, so by providing an oil supply port at the top of the frying pan, it was also possible to avoid the endless conveyor from interfering with attaching and detaching the endless conveyor. I think it's something.

However, in such conventional oil supply means, the oil is supplied only from the bottom of the food being transferred by the conveyor, and the oil temperature decreases over time after being supplied into the frying pan. Therefore, the amount of heat supplied to the food is large at the bottom and small at the top, resulting in a problem that the fried state of the food and the color change due to the fried tofu become uneven.

In addition, due to the explosive release and rise of water in the food during deep-frying, and the inflow of oil from the bottom of the frying pan, an upward flow of oil is created near the food, so the food is exposed to water from below. A pressing force is applied.

For this reason, when the food is instant noodles and is fried in oil in the manufacturing process, the pressing force of the oil from below is applied, so the aggregate of noodles is loaded with the pressing force in the container containing the noodles on the endless conveyor. As a result, the noodle aggregate is dense at the top and sparse at the bottom, and is formed by being fried in that state.

Therefore, if the bread comes into contact with other things in the subsequent process, the sparse parts will be fragile and will break, resulting in insufficient weight.
Additionally, when toma is cooked in boiling water as instant noodles in a container, the noodles are dense and dense, resulting in variations in heat transfer, resulting in some parts being edible and others not. .

This invention was made to eliminate such conventional problems, and its purpose is to adjust the oil temperature distribution in the frying pan to perform deep-frying processing that is suitable for the type and properties of the food. Its purpose is to allow a flow of oil from above the food, applying pressure to the top of the food if necessary; The object of the present invention is to suppress the complexity of the structure and the increase in cost as much as possible by using a framework for supporting an endless conveyor.

That is, the present invention connects the inside of the frying pan 1 and the external heating device 2 through a conduit 26, so that the oil 3 heated by the heating device 2 and introduced into the frying pan 1 passes through the endless conveyor 4. In the apparatus for frying food 5 during transfer by the conveyor 4, the endless conveyor 4

7, at least between the oil inlet 29 and the oil outlet 30 is constructed of a pipe, thereby forming an oil feed path 28 through which the two communicate.

In addition, when a pipe is used also in a part other than the oil feed path 28, it goes without saying that that part and the oil feed path 28 are cut off.

Further, in this embodiment, some of the vertical frames 39 and the lower horizontal frame 3
8, the oil feed passage 28 is not formed, and the upper frame 3
6 and the upper horizontal frame 37, no oil feed passage 28 is formed at all, but the configuration of the oil feed passage 28 can be arbitrarily set according to the structure of the frame 27.

It may be made adjustable.

An oil supply port 31 is installed in the bottom 1c of the frying pan 1 at a position where the oil inlet of the oil feed path 28 is connected when the framework 27 is attached to the frying pan.

As shown in FIG. 4, this oil supply port 31 includes a guide 31b that expands upward, and a heat-resistant material such as silicone rubber.
An oil-resistant 01J ring 31b is provided to form a connection between the oil inlet 29 and the oil supply port 31.

This connection may have other configurations, and its location does not necessarily have to be at the bottom 1c of the frying pan 1.

Further, a stepped portion 41 is formed on the upper edge of the frying pan 1, and by placing the machine frame 12 on this stepped portion 41, the frame 27
is attached to frying pan 1.

A circuit diagram of the chamber 6, the oil drain chamber 20, the oil outlet 30, and the external heating device 2 is shown in FIG.

The heating device 2 consists of a heat exchanger provided separately from the frying pan 1, is connected to a boiler that is a heat source 21, and is configured to heat oil with hot steam.

On the discharge side of the heating device 2, four main pipes 7 are continuous in parallel on the downstream side of the valve 42, and each main pipe 7 has a group R.
Four consecutive branch pipes 8 are connected in parallel to each of the four chambers 6 forming the structure.

Thus, one main pipe 7 has the function of supplying oil to one group R.

Each main pipe line γ is provided with a valve 22 for adjusting the flow rate, and each branch pipe line 8 is provided with a valve 22 for adjusting the amount of oil 3 supplied to each chamber 6 of one group R. A valve 9 is provided.

The oil drain chamber 20 also includes a return pipe 24 equipped with a filter 23.
The discharge side of the pump 25 is connected to the inlet of the heating device 2 via the suction side of the pump 25 .

Further, a pipe line 26 is connected between the heating device 2 and the valve 42, and this pipe line 26 consists of a main pipe line 26a and a branch pipe line 26b connected in parallel to the main pipe line 26a. road 26a
A valve 32 is provided in the branch pipe line 26b, and a valve 33 is provided in the branch pipe line 26b.

The oil supply port 31 is formed at the tip of the branch pipe line 26b, and is continuous to the oil outlet 30 via the oil feed line 28.

The valves 9, 22, 32, 33, and 42 may be either manual valves or automatic valves.

Next, the effect will be explained.

A predetermined amount of oil 3 is always kept inside the frying pan 1, the chamber 6, the pipes 7, 8, 24, 26, the oil feed line 28, etc.
It is filled with oil 3 so that it is provided.

The oil 3 is then discharged by the pump 25, heat exchanged and heated by the heating device 2, and reaches the main pipe line 7 on the other hand.

Then, a predetermined amount of oil 3 is branched to a branch pipe line 8 by a valve 22 and supplied to the chamber 6.

Since a uniform amount of oil is not supplied from the main pipe 7 to each branch pipe 8 due to the fact that the distance between the main pipe I and each branch pipe 8 is not the same, the valve 9 Settings are made in advance so that a uniform amount of oil passes through each branch pipe 8.

As a result, an equal amount of oil is supplied to each chamber 6 of the same group R, which is guided by the slope 6b of the chamber 6 and supplied into the frying pan 1 from the oil outlet 6c.

In this way, the heated oil 3 is evenly supplied into the frying pan 1 in the width direction, so that the temperature distribution of the oil 3 becomes uniform in the width direction of the frying pan 1.

In addition, when changing the oil temperature distribution inside the frying pan 1 in the longitudinal direction by the oil supplied from the oil outlet 6c, the amount of oil supplied from each group R is adjusted by adjusting each valve 22 of the four main pipes 7. This is done by changing the .

For example, if the oil temperature near the inlet 1a is to be higher than that near the outlet 1b, the oil supply amount from group R on the inlet 1a side should be
It would be better to use a dog instead of the one on the side.

Even if the amount of oil supplied from each group R is changed by the valve 22, the amount of oil supplied between the four chambers 6 in each group H is changed by the valve 9.
Therefore, the oil temperature in the frying pan 1 near each group R is maintained uniform in the width direction.

On the other hand, the oil that has come out of the heating device 2 and reached the pipe line 26 enters each branch pipe line 26b from the main pipe line 26a, and then enters the oil supply port 3.
1 and connected via the O ring 31b.
The oil is introduced into the oil feed path 28, and the oil outlet 30 at the tip of the oil feed path 28 is introduced into the oil feed path 28.
From there, it is ejected toward the upper surface of the endless conveyor 4.

The amount and flow rate of oil ejected from the oil outlet 30 are controlled by the valve 32.
33.

Thus, the oil outlet 6 provided at the bottom 1c of the frying pan 1
Not only can the amount of oil supplied from c and the amount of oil supplied from the oil outlet 30 to the upper surface of the endless conveyor 4 be controlled, but also the amount of oil supplied can be controlled in the area in the moving direction of the endless conveyor 4. Therefore, the temperature distribution of the oil in the frying pan 1 can be optimally adjusted depending on the type and condition of the food 5.

Moreover, pressure can be applied from above to the food product 5 by the flow rate of the oil supplied from the oil outlet 30.

From this, the upward flow from the oil outlet 6c, the upward flow caused by the explosive release and rise of the moisture in the food 5, and the upward flow from the food 5
The pressure applied to the food 5 from below due to its own buoyancy,
It can also be suppressed by the pressure from above.

As a result, when the food 5 is instant noodles, the density of the noodle aggregate can be made uniform in the vertical direction, and the downward flow rate from the oil outlet 30 can be adjusted to increase the pressure. By making it into a dog, the density of the noodle aggregate can be made dense at the bottom and sparse at the top.

Then, the same amount of oil as that supplied from the oil outlets 5c and 30 is sucked from the oil drain chamber 20 into the return pipe 24, filtered by the filter 23 on the way, and sent to the heating device 2 via the pump 25. The tag is then heated again and circulated into the frying pan 1 as described above.

In this way, the food 5 such as instant noodles is stored in the container 11 of the endless conveyor 4 in the oil 3 which has an appropriate temperature distribution in the longitudinal direction of the frying pan 1 and a uniform temperature distribution in the width direction. and during this passage they are fried.

The food 5 is not fed into the container 11 at the receiving section 13, and the food 5 that comes out of the outlet 1b of the frying pan 1 is discharged from the container 11 at the discharge section 14 when the endless conveyor 4 is reversed and is supplied to the next process. Ru.

While passing through the oil 3, the upper surface of the container 11 is covered by the presser conveyor 15, so that the food 5 is prevented from floating away from the container 11.

In addition, when cleaning the inside of the frying pan 1, the oil supply is stopped and the lifting machine 1 is rotated by rotating the motor 11.
Activate 6.

That is, due to the rotation of the rotating shaft 16c, the gear box 1
When the gear in 6b is rotated, the gear box 16b rises along the screw shirt N6a and pulls up the frame 27 such as the machine frame 12.

Along with this, the lid 18 supported by the framework 21, the endless conveyor 4, and the presser conveyor 15 rise together, so the upper surface of the frying pan 1 is opened and only the oil 3 remains inside.

Therefore, if oil 3 is drained, bottom 1c of frying pan 1
It is easy to clean the pieces of food 5 that have settled on the top surface.

At this time, the interior of the chamber 6 can be easily cleaned by rotating the top plate 6d on the top surface of the chamber 6 about the hinge 6e to open the top surface of the chamber 6.

When the framework 27 rises, the vertical frame 39 also rises together, so that the oil inlet 29 at its lower end is separated from the oil supply port 31.

Then, by lowering the framework 27 in the opposite direction and attaching the framework 27 to the frying pan 1 again, when the machine frame 12 of the framework 2γ is placed on the stepped portion 41 of the frying pan 1, the oil inlet 29 or oil supply port 31.

At this time, even if there is some discrepancy between the two 29.31,
Guided by the guide 31a, both 29 and 31 are securely connected to the state shown in FIG. 4.

In addition, if the lower part of the vertical frame 39 is made to have an expandable structure that is biased in the direction of extension, the oil inlet 29 will come into pressure contact with the oil supply port 31, and some dimensional errors can also be absorbed thereby.

In this embodiment, since the oil supply port 31 and the oil inlet 29 are connected within the frying pan 1, even if oil leaks from this connection, there is no risk of it leaking outside.

As is clear from the above, according to the present invention, the temperature distribution inside the frying pan can be freely adjusted in the vertical and longitudinal directions, so that uniform deep-frying processing that is adapted to the type and properties of the food can be performed. can.

Furthermore, according to the present invention, not only heat can be supplied by supplying oil, but also pressure can be supplied by the flow of oil from above the food, so that the balance with the pressure applied to the food from below can be adjusted. You can also do it.

Further, according to the present invention, since the oil passageway for supplying the oil to the upper surface of the food is constructed using a framework for supporting an endless conveyor or the like, the framework also serves most of the oil passageway.

Therefore, the complexity of the structure and the increase in cost can be suppressed as much as possible.
