Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating method and a heating device for heating small, soft pieces of refined food raw material.

Refined foods refer to fish meat, preserved meat, or those mixed with vegetable protein seasonings and stirred to form a paste-like raw material, which is then shaped into a predetermined shape and heated. The conventional heating method will be explained using the case of hanpen as an example.

The hanpen raw material formed into a predetermined shape is heated by placing it in boiling water. in this case,
Hanpen raw materials contain air, so their specific gravity is 1.
It is smaller, and although it varies depending on the air content, the upper half of it is above the surface of the hot water. Therefore, a method has been implemented in which the raw material for hanpen is heated from the entire surface by forcing it to sink below the surface of the hot water.

Ideally, the center and surface of such a refined food material are heated to approximately the same temperature.
However, because the temperature of the water is much higher than the optimum temperature in order to sufficiently heat the center of the raw material, the center of the processed food material is heated to the appropriate temperature, but the surface portion becomes slimy due to excessive protein denaturation due to the high temperature. It becomes moist. On the other hand, if the temperature of the water is lowered so that the surface area is at an appropriate temperature, the center area will be insufficiently heated, and in any case, the raw material for refined food cannot be heated properly.

Therefore, the present invention aims to eliminate such drawbacks and heat the entire refined food raw material to a uniform temperature. The configuration of the heating method of the present invention to achieve such an object is to simultaneously heat the lower part of the small piece-shaped refined food raw material with boiling water and the upper part with steam, and to turn the refined food raw material over. It is characterized by the fact that
The configuration of the heating device is to install multiple boiling tanks filled with boiling water in the lower part and steam in the upper part, and to transport small pieces of condensed food ingredients within each boiling tank and between each boiling tank. The present invention is characterized in that a means is provided across the boiling tanks, and further includes a reversing means for reversing the refined food material between each boiling tank.

Hereinafter, the present invention will be explained in detail based on an embodiment shown in the drawings.

A boil tank according to the present invention is shown in FIGS. 1 to 3. In this embodiment, a plurality of long boiling tanks 1 are stacked to form a multistage boiling tank, which can be installed even in a narrow place. The long boil tank 1 is composed of a frame 2 and a hood 3, as shown in a cross-sectional view in FIG. A rail 4 is welded to the inner surface of the long boil tank 1. A pipe 5 is attached to the frame 2 for supplying heat to the boiling water filled inside to keep the water temperature constant, and pressurized steam is flowed through the pipe 5. A hood 3 is detachably attached to the top of the frame 2, and the inside of the tank is sealed except for both ends. The hood 3 has a pipe support 6'
The pipe 6 is attached via the. The pipe 6
is provided with a number of holes (not shown), and the pressurized steam supplied into the pipe 6 enters the tank through these holes. Note that if a plug (not shown) provided at the bottom of the frame 2 is removed and cleaning water is allowed to flow into the pipe 6, water will be sprayed from the hole, making it easy to clean the inside of the tank. As described above, the inside of the long boil tank 1 is filled with boiling water at the bottom and steam at the top. In this embodiment, such long boil tanks 1 are stacked in five stages, and the bottom long boil tank 1 is used to store small piece-shaped hanpen raw material 7 formed as a raw material for condensed food.
It is longer than the others because it carries the conveyor 8 that carries it. Note that 22 is the hot water level.

In this embodiment, a chain belt 9 is provided as a conveying means for moving the starch raw material 7 inside each long boiling tank 1 and between each long boiling tank 1. The chain belt 9 connects the flat plate 10 to the side plate 1.
1, a chain is connected by a pusher 13, and rollers 12 are rotatably provided between the side plates 11, which are successively sandwiched from both sides so as to be rotatable. The pusher 13 has the function of separating the hanpen raw materials 7 floating on the boiling water from each other and pushing them away. Flexible chain belt 9 as described above
is placed on the rail 4 and moved within the long boil tank 1 by a drive source (not shown), and is moved to the upper long boil tank 1 by a reversing device 14 as a reversing means. In other words, the chain belt 9 moves the long boiling tank 1 in the first stage from left to right in the figure, then moves from right to left in the second stage, from left to right in the third stage,
It has an endless structure in which it moves from right to left in the fourth stage, from left to right in the fifth stage, finally moves to a packaging factory (not shown), and returns to the long boil tank 1 in the first stage.

The reversing device 14 not only guides the chain belt 9 to the upper elongated boiling tank 1, but also inverts the raw material 7 and moves it to the upper elongated boiling tank 1.
The reversing device 14 is composed of a sprocket 15 and guides 16 and 17. The sprocket 15 is provided with a recess 18 in the center around the entire circumference so that the hanpen raw material 7 can be accommodated therein. The guide 16 is provided from the lower elongated boiling tank 1 to the outer periphery of the sprocket 15, and the guide 17 is provided along the sprocket 15.
It extends from the boiling tank 1 to the upper elongated boiling tank 1.
Due to buoyancy, the hanpen raw material 7 that is moved with its upper half exposed above the boiling water in the long boiling tank 1 is pushed by the pusher 13 and placed on the guide 16,
After being automatically turned over at the upper part of the sprocket 15 housed between the guide 16 and the recess 18 of the sprocket 15, it is guided by the guide 17 and enters the elongated boiling tank 1 in the upper stage. Then, boil the water again for 1 hour.
Press 3 to move.

The entire multi-stage boiling tank is covered on both sides to prevent heat from escaping. That is, as shown in FIG. 3, rails 19 are attached to the top and bottom of both sides of the multistage boiling tank, and shutters 20 made of a heat insulating material are provided on the rails 19. Although not shown in FIG. 1, a plurality of shutters 20 are arranged closely from the right end to the left end of the multistage boiling tank.

In addition, in this example, a boil tank having a structure in which a plurality of long boil tanks are stacked in multiple stages is shown, but a plurality of long boil tanks are installed on one plane, and the processed food raw material A boiling tank with a structure that is reversed each time it is moved may also be used. Moreover, a plurality of long boil tanks may be formed by dividing one boil tank instead of collecting a plurality of long boil tanks.

The hanpen raw material 7, which has been formed into a predetermined shape, is conveyed by a conveyor 8 to the boil tank as described above. The hanpen raw material 7 is in the first stage long boiling tank 1.
Inside, the lower half is heated by boiling water and the upper half is heated by steam as it moves from the left end to the right end in the figure while being pushed by a pusher 13. The hanpen raw material 7 is then reversed by the reversing device 14 and conveyed to the second elongated boiling tank 1. Here, the first stage long boil tank 1
The part of the body that was in contact with the boiling water comes into contact with the steam,
The part that was in contact with the steam now touches the boiling water. When the hanpen raw material 7 is transferred from the second stage to the third stage, it is also reversed.In other words, each time the hanpen raw material 7 is moved to the long boiling tank 1 of the upper stage, the hanpen raw material 7 is reversed, so it is heated by boiling water and steam. Since the heating is repeated alternately, the entire starch raw material 7 is heated at a substantially uniform temperature. In this way, the fifth long boil tank 1
By being moved up to this point, the hanpen raw material 7 is hardened and becomes a hanpen. The hanpen is plate 2 installed from the fifth long boiling tank 1 to the packaging area.
1 is pushed by pusher 13 and moves.

As described above with reference to the drawings, one embodiment of the present invention heats the refined food raw material by exposing it to boiling water and steam alternately, so that the whole product is heated to a substantially uniform temperature and no moisture is generated. Further, since the boiling tank is composed of a plurality of long boiling tanks, it is easy to adjust the temperature of each tank, unlike a single boiling tank. Therefore, in the case of processed foods whose proteins are denatured by rapid heating, it is effective to gradually heat them to a high temperature.
