Description

[Detailed Description of the Invention] [Technical Field] The present invention provides a food product that can be beautifully formed into a predetermined shape by preventing deformation or bending when forming mixed and kneaded materials into a predetermined shape food product. The present invention relates to a molding device.

[Prior art]

Conventionally, when mixing and kneading materials in an extruder or the like and molding them into a predetermined shape, the material sometimes sag, resulting in deformation or distortion of the external shape, making it impossible to perform beautiful molding. This was particularly noticeable in materials containing a large amount of moisture, or in cylindrical food items with large diameters or thick walls. In addition, for foods with complicated cross-sectional shapes, in the forming path of the forming device,
The disadvantage was that the materials did not come into close contact and complete molding could not be achieved.

[Purpose of the invention]

The present invention prevents deformation of the outer shape of the food product caused by dripping of the material by suctioning the outer periphery of the material from the peripheral surface of the molding path when the mixed and kneaded materials are molded into a predetermined shape in an extruder or the like. An object of the present invention is to provide a food molding device that prevents bending, enables complete molding of food even with a complicated cross-sectional shape, and can beautifully mold food into a predetermined shape.

[Structure of the invention]

The present invention is an apparatus for forming mixed and kneaded materials into food products of a predetermined shape. , these suction holes are connected to a suction device.

[Explanation of Examples]

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a sectional view of essential parts of a first embodiment of the present invention. In these drawings, 1 is an extruder body for mixing and kneading food materials, and 2 is a die for extruding the materials into a cylindrical shape.

10 is a molding device that molds the material extruded from the die 2 into a food product having a predetermined shape. This molding device 10 is provided with a molding section 11 having a predetermined cross section in the center, and a suction section 12 and a cooling chamber 15 are formed around the molding path 11.

The cross-sectional shape of the forming path 11 in the flow direction can be a predetermined shape, for example, a circular shape as shown in FIG. 2a, or a fish-shaped shape as shown in FIG. 2b. The cross-sectional shape of the forming path 11 may be any shape depending on the type of food and the like. The suction section 12 includes a vacuum chamber 14 formed around the forming path 11 and a large number of suction holes 13 formed in the circumferential surface of the forming path 11. The suction portions 12 are formed at two locations, one at the front and the rear of the forming path 11, and each suction portion 12 is formed with an appropriate width in the flow direction of the forming path 11. Each suction part 1
The second vacuum chamber 14 is connected to a vacuum pump (not shown), etc., so that negative pressure is applied to each suction hole 13.

Cooling water is sent into the cooling chamber 15 from a pump (not shown) to adjust the temperature of the material to a temperature suitable for molding. Furthermore, when molding material fed in at a low temperature, it is necessary to reversely heat the material by using the cooling chamber 15 as a heating chamber. Therefore, whether to use the cooling chamber or the heating chamber depends on the type of material, the temperature of the material fed into the molding apparatus 10, and other factors.

16 is a nozzle, which is located between the die 2 and the molding device 10, and which collects the material extruded from the die 2.
The temperature is easily adjusted to a temperature suitable for molding in the molding device 10, and cold or hot air is blown toward the material. Reference numeral 20 denotes a conveyance device placed behind the molding device 10.

In the molding apparatus 10 in this embodiment, food products are molded in the following manner. Nanawachi,
When the materials mixed and kneaded in the extruder main body 1 are extruded from the die 2, they are cooled or heated by cold air or hot air from the nozzle 16 as necessary. Thereafter, the material is fed into the molding path 11 of the molding device 10, adjusted to a temperature suitable for molding in the cooling chamber (heating chamber) 15, and then flows to the suction section 12. Since negative pressure is applied to each suction hole 31 in the suction section 12, the outer peripheral surface of the cylindrical material is attracted to the suction hole 13, that is, the peripheral surface of the forming path 11, and is molded into a predetermined shape. This kind of molding
This is carried out using the suction sections 12 at the front and rear portions of the forming path 11, and the food is sent out from the forming device 10 to the conveying device 20 as a perfectly shaped food product. Note that this conveying device 20 not only simply conveys the material, but also functions to pull the material from the forming device 10 so that the flow of the material is not blocked even if negative pressure is applied to the material in the forming path 11. are doing.

FIG. 3 shows a second embodiment of the present invention, which is an example of a molding apparatus in which another material is spirally added inside a cylindrical material.

In these side views, 1a and 1b are the extruder main bodies, 2 is a two-layer die, and the center die nozzle 2
a rotates and adds another material spirally to the inner peripheral surface of the cylindrical outer skin material.

The basic configuration of the molding device 10 is the same as that of the first embodiment, but in the case of this embodiment, the suction section 12 is made large in order to mold a material in which another material is added inside the cylindrical material. It has a structure that provides suction power. That is, in the apparatus of this embodiment, the suction part 12 formed at the front part of the forming path 11 is
It is designed to be wide in the direction of flow of the material and to strongly attract the outer periphery of the material. In the illustrated molding apparatus 10, only the front suction part 12 is formed widely in the material flow direction, but it is also possible to form the rear suction part 12 in the same way.
It is also possible to form a wide range of chisels.

In addition, as a means for providing a strong suction force to the suction part 12 in the molding device 10, the suction part 12
There are ways to increase the number of suction holes 13, increase the density of the suction holes 13, or increase the horsepower of the vacuum pump.

In this way, if the force of the suction part 12 of the molding device 10 can be increased, it becomes possible to mold not only cylindrical materials but also rod-shaped materials and materials whose entire interior is filled with other materials. , can be used in a wide range of areas.

The food products targeted by the molding apparatus of the present invention include a wide range of seafood products, pet foods, and the like.

〔Effect of the invention〕

According to the present invention as described above, when forming a material into a predetermined shape, it is possible to prevent the outer shape of the food from being bent or bent due to sagging of the material, and it is also possible to prevent food products having a complicated cross-sectional shape. It also enables complete molding, allowing food to be beautifully molded into a predetermined shape. Furthermore, the molding apparatus of the present invention has advantages such as a simple structure, easy operation, and short molding time.
