Description

[Detailed description of the invention] The present invention provides bonito, salmon, tuna, mackerel, horse mackerel, sardine,
Fish and shellfish joints such as shrimp, squid, octopus, and shellfish, dried fish, and dried sardines that have been cut or crushed into small pieces (small pieces are left as is), vegetables, seaweed, etc. that have been cut or crushed in the same way A sheet-shaped food product made by mixing small pieces with the above (hereinafter referred to as flake-shaped raw materials), adding seasonings and binders as necessary, and forming it into a thin continuous sheet-shaped food while heating and pressurizing it. It relates to food manufacturing methods and equipment. Conventionally, various attempts have been made to form dried bonito flakes into sheet shapes. A generally known method is to place the shaved knots, etc. in a press mold of a predetermined shape and pressurize it. however.

With this method, a single item with a predetermined shape is made, and a long item (
It cannot be used to produce sheet-like materials, so its uses are limited.

The cost is also high and it is not economical. Therefore, as a result of studying to provide a continuous sheet-shaped food, the present inventor first found that
Developed a method and device for converting the flaky raw material dispersed on the lower belt into flaky sheets using heated pressure rollers built into each belt between the upper and lower belts, which rotate in opposite directions. - Proposed in No. 17721.

The present invention has been further simplified by making use of that experience, and while continuously supplying flaky raw materials, etc. onto the moving surface of a belt conveyor including at least one heating roller, This is a method for manufacturing a sheet-shaped food product characterized by forming it into a continuous sheet by heating and pressurizing it with a heating pressure roller that is pressed against it, and it is a method that does not include an upper belt, and it also relates to an apparatus used therein.

The method disclosed in Japanese Patent Application No. 58-17721, which is an earlier invention of the present invention, is to feed the flaky raw material onto the lower belt, sandwich it with the upper belt, and press it vertically with upper and lower rollers. This is an attempt to compress the raw material into a sheet by applying heat and pressure at the area where the rollers contact (hereinafter referred to as the tangential area). In this prior invention, the raw material was sandwiched using upper and lower belts, and several sets of upper and lower rollers were used to heat and press the material to crimp it. Since the surface area is small and insufficient, several sets of upper and lower rollers are provided, and the raw material heated and pressed by the upper and lower rollers of the first stage is not attached to the rollers, but is transferred to the rollers of the second stage. In order to transfer accurately, not only a lower belt but also an upper belt is provided, and the raw material is sandwiched between the upper and lower belts.

However, when designing a device using this method and actually operating it, it was found that it had the following drawbacks.

That is, (1) the equipment becomes larger and the equipment cost increases;

- Except for the upper first stage roller, the contact area between the belt and the rollers is small, so there is little heat transfer and poor thermal efficiency. ■Since the equipment is large and uses belts at the top and bottom, the belts deteriorate quickly due to heat and pressure, increasing belt consumption costs.

The present method and apparatus solve these above-mentioned drawbacks, and a specific example thereof will be described below with reference to the drawings.

Figures 1 and 2 are 1-stage pressure welding, Figure 3 is 2-stage pressure welding, and 4th stage pressure welding.
The figure is a schematic diagram showing a case of three-stage pressure welding.

In FIG. 1, the belt conveyor is composed of a belt (1) and rollers (2), (3), and (4) for tensioning the belt, and is provided with a heating roller (5) in contact with the inner surface of the intermediate portion of the belt (1). A heating pressure roller (6) is provided that presses the belt (1) from above so as to be inclined slightly rearward from the heating roller (5) and contact the belt (1) at a contact point A. In other words, the axes of the heating roller shaft and the heating pressure roller shaft are inclined from perpendicular, and the heating and pressing roller and the conveyor belt are in surface contact with each other on an arcuate surface. Therefore, even after this heated pressure roller (6) comes into pressure contact with the heated roller (5), the belt (
1) and point B are in contact with each other over a wide area.

A flaky raw material (10) such as fish flakes is supplied from a slit-shaped hopper (11) to the front of the belt (1) and spread on the belt, and then a processing liquid (10) containing seasonings and a binder is fed to the front of the belt (1).
2) is added to the mist box (13) and moves together with the belt, and is transferred to the heating roller (5) via the belt (1).
), and is directly heated and pressed by this heating and pressing roller at a pressing point A that is tangential to the heating and pressing roller (6). After passing point A, the flaky raw material (10) is heated while being pressed against the heating pressure roller (6) by the belt (1), moves and presses as the roller rotates,
By the separation point B between the roller and the belt, it becomes a sheet, and when it is lifted off the belt (1), it is heated and pressurized by the roller (6).
It separates and comes out as a sheet-like product (14).

In addition, if a lower surface spray (15) is provided in front of the belt (1) and a liquid consisting of water, seasoning, binder, etc. is sprayed onto the belt surface prior to molding, the sheet-like product (14) can be sprayed onto the belt surface. )
These can be attached to the back side of the paper to increase binding strength. The bottom spray (15) is also connected to the mist box (13).
In the latter case, the spray nozzle is placed inside the sealed box, and the mist is allowed to fall naturally through the lower opening of the box, so the mist does not scatter outside the device, and in the latter case, the flaky raw material on the belt is blown away. Therefore, a hygienic and uniform sheet-like product can be obtained.

In Fig. 2, contrary to Fig. 1, the tangential pressing point A between the heating roller (5) and the heating and pressing roller' (6) is at the back, and the heating and pressing roller (6) is placed in front of it. There is a contact point C where the belt (1) comes into pressure contact, and the flaky raw material (10) is first lightly pressed between the heated pressure roller (6) and the belt (1), and then the heated pressure roller (6) It is a figure which shows the method of making a sheet-like product (14) into sufficient pressure contact with the heating roller (5) at the pressurizing point A. The type of flaky raw material determines whether, as shown in Figure 1, first strong pressure is applied and then 1-low pressure is continued for a while, or vice versa, and whether strong pressure is applied after weak pressure as shown in Figure 2. The decision should be made depending on the type of binder, but in any case, it was confirmed that a good product could be obtained by combining only the lower belt, which is not a double-sided belt, and a roller.

If the pressing force is insufficient with only one heating roller (5), it can be dealt with by increasing the number of lower heating rollers (5). Figure 3 shows A with two heating rollers (5) (5).

Both points B are in pressure contact with the heating pressure roller (6), and in Fig. 4, another heating roller is installed to increase the contact distance between the belt and the heating pressure roller (6). This is an example in which (5) is added and pressure is applied even at the midpoint between A and B. Furthermore, if necessary, the sheet-like product (14) can be passed between two separate finishing rollers.

According to the method and apparatus of the present invention, the following effects can be obtained.

■Since this method heats and presses the belt from above using rollers, belt wear is reduced to about 1/2 compared to the upper and lower belt clamping method.

■Since the number of heating and pressing rollers is small, the device can be made smaller and equipment costs can be reduced.

■Since the contact area between the heating pressure roller and the belt is large,
Heat is used efficiently.

■Continuous production of sheet products is possible and productivity is high.
