Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to food extrusion, in which food materials put into a cylinder are kneaded and extruded through an extrusion die provided at the tip of the cylinder to produce foods with various cross-sectional shapes. It is related to manufacturing machines.

[Conventional technology]

In general, this type of food extrusion manufacturing machine has one or more screws disposed inside the cylinder, and the rotation of the screws kneads the food materials while applying pressure, heating, etc. to the tip of the cylinder. It is extruded from a nozzle provided. In order to form the extruded food into a predetermined cross-sectional shape, an extrusion die having a through hole corresponding to the cross-sectional shape is attached to the nozzle.

Conventionally, when manufacturing thread-like or fibrous food materials with a very small diameter, it has been necessary to form the through holes of the extrusion die very small.

[Problem that the invention seeks to solve]

However, when the diameter of the through-hole formed in the extrusion die becomes very small, processing is difficult, and depending on the food raw material, the through-hole is often clogged during use.

[Means for solving problems]

The technical means taken by the present invention to solve the above problems is to provide a thin plate-shaped net having a mesh smaller than the diameter of the through hole of the extrusion die together with the extrusion die.

[Effect]

Inside the cylinder, the food material pushed forward by a screw or the like becomes fibrous as it passes through a thin plate-like net, and is pushed out from a nozzle.

〔Example〕

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

FIG. 3 shows the front end of the food extrusion manufacturing machine according to the present invention, and in this embodiment, two screws 2 are disposed within the cylinder 1.
3 is an adapter attached to the front end of the cylinder 1, and 4 is a nozzle attached to the front end of the adapter 3.

5 is an extrusion die having a large number of through holes 6, and a thin metal net 8 is removably fitted into a recess 7 at its rear end. The size of the mesh of this net 8 is smaller than the diameter of the through hole 6 formed in the extrusion die 5, and is changed depending on the diameter of the fibrous food product to be manufactured. At the tip of nozzle 4,
An extrusion hole 9 is bored.

Next, the usage conditions of this food extrusion manufacturing machine will be explained.

Powdered or granular food materials such as starch such as rice or wheat or protein such as soybeans are added to the cylinder 1 as needed and are then kneaded and pressurized by the screws 2 and 2. , is subjected to treatments such as heating, and is pushed forward. The food material that has reached the front end of the cylinder 1 becomes fibrous when passing through the mesh of the net 8, and becomes fibrous through the through hole 6 of the extrusion die 5.
It is extruded through the extrusion hole 9 of the nozzle 4 to the outside. The extruded fibrous food material is usually expanded, but it is of course possible to have it in an unfoamed state.

Since the food material made fibrous by the net 8 passes through the through holes 6 having a diameter larger than the mesh of the net 8, the fibers do not overlap again when passing through the extrusion die 5. Further, in this embodiment, the net 8 is arranged at the rear end of the extrusion die 5, but it can also be arranged at the front end. However, in this case, a support member such as a perforated plate for supporting the net 8 is required. In the illustrated embodiment, the extrusion die 5 serves as a support for the net 8.

This fibrous food has a wide range of uses, such as being used as a dough for other foods in the form of granules or powder, or mixed into various foods as a filler. When mixed as a bulking agent in pastries such as sweets and kamaboko, it has the advantage that it does not remain in the mouth when eaten.

〔Effect of the invention〕

This invention has the above-described configuration and has the following effects.

(a) Without reducing the size of the through hole 6 of the extrusion die 5,
Fibrous foods can be produced simply by providing the net 8.

(b) Since the net 8 has a thin plate shape, even if the mesh is small, it is unlikely to be clogged with food materials.

(c) When changing the fiber diameter, it can be easily changed by simply replacing the net 8 with a different mesh.
