Description

[Detailed description of the invention] <Purpose of the invention> Industrial field of application The invention relates to a food dough molding device, and more specifically, the food dough is extruded into a molding chamber through an extrusion nozzle, and the molded food dough is The present invention relates to a food dough molding device that allows the mold to be smoothly released and taken out from the molding chamber, and in which a part of the molding chamber can be easily opened.

BACKGROUND ART Conventionally, various molding methods and molding devices have been used for materials such as metals and synthetic resins. Among these, synthetic resins are usually molded using extrusion methods, injection methods, etc.
Various molding devices have been developed according to each of these molding methods. It is also possible to use these molding devices to mold food dough into a desired shape.
It is difficult to apply this molding device as is.

In other words, an extrusion molding device continuously extrudes materials such as iron or synthetic resin into a plastic state through a predetermined die, and extrudes and molds the material into, for example, a pipe or cylinder, and is basically constructed on a continuous molding basis. ing. Although this extrusion molding apparatus has been modified to some extent and is used for molding long foods such as noodles, it has not been used for molding foods that are not continuous. Injection molding equipment, on the other hand, was originally developed from zinc die casting equipment, and consists of a pressurizing chamber that pressurizes a material such as synthetic resin as a liquid, and a nozzle that injects this material at high pressure. It consists of dice.

In addition, the die of the injection molding apparatus is constructed so that the entire die is open, and after molding, the die is opened each time to take out the molded product, which has the advantage that even complex-shaped molded products can be molded. In addition, in order to make it easier to release the molded product from the die, a release agent such as zinc stearate is added to the material in advance, and a release agent such as silicone is added to the die when the die is opened. Must be applied manually to the molding chamber. Furthermore, from the viewpoint of improving moldability, for example, a pressure of 400 kg/
It is necessary to make the injection pressure from the nozzle very high, such as cm ² .

However, unlike synthetic resins and the like, when too much force is applied to food dough when it is injected from a nozzle, the material breaks down and loses its texture and taste, as well as becoming pasty and becoming highly sticky. Furthermore, unlike synthetic resins, additives such as mold release agents cannot be added to food dough.

For this reason, the food dough is molded using an injection molding machine,
In particular, even if the molding pressure is significantly lower than that of synthetic resins, the material will break, food dough will adhere to the molding chamber in the die, and smooth molding will not be possible.

From this point of view, the present inventor first intermittently sends a predetermined amount of food dough from the hopper to a communication chamber, and extrudes a predetermined amount of food dough in the communication chamber from an extrusion nozzle to a molding chamber using a plunger. We have developed a molding device that molds into desired shapes.

In this molding device, the molding pressure when extruding with a plunger is not very high, and the molding is performed within the molding chamber, and the food dough can be individually molded into complex shapes. However, even with this molding device, the food material itself is sticky, and if the molding pressure is increased depending on the molding shape, the stickiness will further increase.
When the molded product is released from the molding chamber, some of the food dough adheres to the inner wall surface of the molding chamber, and as molding is repeated, this deposit increases and may make molding difficult. In addition, unlike synthetic resins, food dough cannot be removed after being molded by opening the die or molding chamber and dropping the molded product. Therefore, even if the molding chamber is opened, the molded product does not lose its shape. Although it must be constructed so that it can be taken out, no such structure has been proposed.

Problems to be solved by the invention The invention aims to solve the above-mentioned drawbacks. Specifically, the invention aims to solve the above-mentioned drawbacks. Specifically, the molding chamber, where the food dough fed in predetermined amounts is extruded from the extrusion nozzle by a plunger, is connected to the tip of the extrusion nozzle. The second molding part is formed inside a sliding outer cylinder that is slidable with respect to the first molding part, and the second molding part is formed inside a sliding outer cylinder that is slidable with respect to the first molding part. To propose a molding device that can smoothly release and take out a molded food dough (hereinafter simply referred to as a molded product) by forming a leaching hole on the inner wall surface of a first molding part to let liquid such as water leak out. .

<Structure of the invention> Means for solving the problem and its operation In other words, the molding device according to the invention is provided with a pressing nozzle at the tip of the pressing passage through which the food dough is fed while being pressed, and the tip of the pressing nozzle is A food dough molding device including a molding chamber in which food dough is extruded and molded into a desired shape, the molding chamber being connected to an extrusion nozzle and integrally attached to a pressing passage; When the sliding outer cylinder provided on the outside of the first molding part is slid and stretched along the axis of the molding chamber, a second molding part is formed inside the sliding outer cylinder at the extended position. A seepage port is provided on the inner wall surface of the first molding part to let out liquid such as water, and by retreating the sliding outer cylinder, part or all of the second molding part disappears, and a part of the molding chamber is removed. It is characterized by being made open.

The material is then extruded into the molding chamber 8 and molded.

That is, for example, when producing squid imitation foods and molding the squid body from a food dough 2 mainly made of surimi, the food dough 2 is fed from the top of the hopper 1 in FIG. 1. At this time, the press passage 5 is closed by the switching valve 9, while the outlet of the hopper 1 is opened to guide the food dough 2 into the communication chamber 3. After a certain amount of food dough 2 has been sent, the switching valve 9 Rotate to close the discharge port of hopper 1. In this state, the communication chamber 3 and the pressure passage 5
When a predetermined amount of food dough 2 in the communication chamber 3 is pushed out by the plunger 6 on one side of the communication chamber 3, this food dough 2 is pushed out into the pressing passage 5, Furthermore, an extrusion nozzle 7 is connected from the press passage 5.

Therefore, when taking out the molded product 2a, a part of the molded product 2a is held in a part of the molding chamber 8, so that it can be taken out without falling and without damaging the shape.

Furthermore, when molding the body of squid imitation foods, for example, as shown in FIGS. 1 and 2,
In addition to the molding chamber 8, a core 10 is used, and in the molding chamber 8, the sliding outer cylinder 11 is extended to form a second molded part 8b therein, and the molded part in which the second molded part 8b is formed is formed. The core 10 is inserted into the chamber 8, the food dough 2 is extruded from the extrusion nozzle 7 around the core 10, and after molding, the molded product 2a of squid food is made using the core 10 as a take-out device. Take it out. That is, the end portion of the core 10 is gripped, and this gripping device (not shown) is configured to be able to reciprocate along the axis of the molding chamber 8. Therefore, during molding, the core 10
is advanced into the molding chamber 8, as shown in FIG.
In this state, the food dough 2 in the press passage 5 is extruded through the extrusion nozzle 7 by the pressure extruded by the plunger 6, and a molded product corresponding to the body is formed around the core 10. Molded. Thereafter, a part of the molding chamber 8 is opened by eliminating all or part of the second molding section 8b, and the molded product 2a is taken out. That is, after molding, the sliding outer cylinder 11 is slid in the backward direction to eliminate part or all of the second molding part 8b and open a part of the molding chamber 2, while the core 10 is removed. When the second molded part 8b disappears and the molded part 2a is exposed, the molded part 2a corresponding to the body moves together with the core 10 and is completely separated from the first molded part 8a. taken out. In addition, if only the core 10 is removed by heating after being taken out, only the molded product corresponding to the body will be obtained.

Next, as described above, the molding chamber 8 is constructed in a partially open type, and in this molding chamber 8, the inner wall surface 8a' of the first molding part 8a and the inner wall surface 7' of the extrusion nozzle 7 are formed.
