Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to molds for processing and molding various foods, such as for confectionery and for producing fish paste products.

[Conventional technology]

Conventionally, it has been common practice to color foods before or after molding, which often results in uneven coloring.

In addition, when molding food into complex shapes, such as small animals such as turtles and rabbits, flowers such as violets and chrysanthemums, and fish and shellfish shapes such as shrimp, crabs, and lobsters, molds are Because it was difficult to remove the product from the frame, scratches and defects often occurred.

Furthermore, a device that moves a large number of baking molds (forms) and a device that opens and closes the molds also needs a structure that prevents uneven coloring, scratches, and the like.

[Problems to be Solved by the Invention] Therefore, the present invention aims to prevent uneven coloring, scratches and defects during mold cutting, and also to prevent the same in devices where the mold moves or opens. It is intended to.

[Means for solving problems]

Therefore, in this invention, a porous plate is used at least in the part where the product mold is formed, as a mold for a food manufacturing device that has a plurality of molds and shapes and bakes raw material dough while circulating the molds. In addition, a nozzle was provided on the outer surface of the mold so that it could be contacted and removed, and the nozzle was used to carry out ventilation and/or liquid passage through the porous plate.

[Effect]

This invention uses the above means to provide a porous plate with excellent air permeability and liquid permeability, so when a colorant or gas is pressurized, the colorant or gas can be sprayed over the entire product, resulting in uniform coloring and liquid permeability. It is possible to perform mold cutting without scratches or defects.

In addition, aeration and liquid flow to the porous plate are performed by contacting and removing nozzles from the outside surface of the formwork, so it is possible to repeatedly aerate and pass liquid through the moving formwork with a small number of nozzles, and also to open and close the formwork. Ventilation without obstructing,
Can pass liquid.

〔Example〕

The production of food using the food processing mold according to the present invention is generally carried out by press-fitting confectionery dough or dough for pastry products made from various materials into the mold, attaching a coloring agent, and going through steaming, toasting, etc. The mold is cut while pressurizing air from the outside.

A specific example thereof will be explained in accordance with a food manufacturing apparatus having a two-part mold.

As shown in FIGS. 5 and 6, two guide rails 4 are movably installed on the device main body 1 by a drive wheel 2 and a driven wheel 3.
A plurality of mold units 5 are disposed on the guide rail 4, and are moved cyclically between the wheels 2 and 3 as the guide rail 4 moves.

The mold unit 5 is held between one guide rail 4 by four rollers 6, and a pair of molds 8 are attached between the two guide rails 4 via a mold stand 7.

The formwork 8 has a double structure consisting of a substrate 9 and a porous plate 10 on which a shrimp-shaped mold is formed, as shown in FIGS. 1 to 4, and has several holes inside the substrate 9. 11, and the colorant and air are forced into the formwork 8 from the outside. In addition, 12 is a hopper, 13 is a coloring nozzle, 14 is a burner, and 15 is an air nozzle.

The pair of formworks 8 are opened and closed in left and right opposite directions around the shaft 16.

Next, a method for manufacturing food using the mold 8 will be explained.

The mold unit 5 is conveyed to the upper left end of the guide rail 4 by the rotation of the drive wheel 2, and the raw dough is supplied from the hopper 12 to the closed mold 8 (FIG. 5).

Then, as shown in FIG. 3, the coloring nozzle 13
The mold 8 is pressed against both sides of the moving mold 8, and the coloring agent is press-injected for a certain period of time to color the raw material fabric. When coloring is completed, the coloring nozzle 13 separates from the mold 8 and returns to its original position. Furthermore, the formwork 8 is fired by the burner 14 while moving along the guide rail 4.

The formwork 8 is opened to the left and right in front of the driven wheel 3. As shown in FIG. 4, the air nozzle 15 comes into pressure contact with the formwork 8 that has passed through the driven wheel 3 and is turned upside down from above, moving with the formwork 8 and injecting air into the formwork 8. Drop the product that sticks to it. The products are collected by an output conveyor 17. When the mold cutting of the product is finished, the air nozzle 15 separates from the mold frame 8 and returns to its original position.

The mold unit 5 is transported to the drive wheel 2, and the mold 8 is cleaned and closed during transport.

In this way, by using each two coloring nozzles 13 and two air nozzles 15, the moving formwork 8
Ventilation and liquid can be passed through the mold without interfering with the opening and closing of the formwork 8.

Then, the mold unit 5 is returned to the upper left end of the guide rail 4, and the same process is repeated thereafter.
Note that the air injection may be performed while the mold 8 is closed after firing, or may be performed while it is opened.

As described above, the porous plate 10 of the formwork 8 allows coloring and molding to proceed simultaneously, prevents uneven coloring, and facilitates mold cutting of the product. The materials include metals such as stainless steel, various ceramics, and heat-resistant plastics such as vinylidene chloride and carbon fluoride resin.

In order to prevent uneven coloring and facilitate mold cutting, it is necessary to minimize the liquid flow resistance and ventilation resistance of the porous plate 10, and these resistances are closely related to the pore diameter and thickness.

Experimental results showed that these resistances were small when the pore diameter was between 30 and 200 meshes, and increased when the pore diameter exceeded 200 meshes. Moreover, when the number of meshes exceeded 200, it was difficult to quickly remove the product from the mold in a complete form. In addition, a porous plate 10 with a hole diameter of 48 to 100 mesh
When "crab scissor-style kamaboko" was produced using this method, the product surface had excellent gloss and texture.

The thinner the porous plate 10 is, the lower the resistance becomes.Although it varies depending on the product, the resistance is small in the range of 0.5 to 30 mm.

"Crab scissor-style kamaboko" is made using a formwork 8 in which a porous plate 10 is fitted into an aluminum block.
When the porous plate had a thickness in the range of 0.5 to 5.0 mm, the product could be completely removed from the formwork 8 with an air pressure of 2 kg/cm ² and the coloring state was excellent.
In this case, when the plate pressure exceeded 10 mm, uneven coloring occurred and fine scratches appeared on the tips of the crab claws.

In addition, the formwork 8 may consist only of the porous plate 10.

〔Effect of the invention〕

This invention has the above-mentioned structure, and the porous plate enables uniform coloring and mold cutting without causing scratches or defects, and the provision of contact-releasable nozzles allows the mold to move. Even devices that open and close can be uniformly colored and completely molded.
