Abstract

PURPOSE:To improve the biting of a raw material of large grain size in the twin-screw molding part, by passing the raw material through a biting part therefor before the twin-screw molding part, and feeding the raw material to the twin-screw molding part. CONSTITUTION:A food biting part 2 having two screws 4 and 4' rotating in the opposite inward directions is provided before a twin-screw molding part 3 rotating in the same direction for performing a series of processings, e.g. kneading, heating and pressurizing, and a raw material is passed through the food biting parts 2 and fed to the twin-screw molding part 3. Thus, the biting of even the raw material of large grain size is improved, and the food can be manufactured with high efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for feeding raw materials with particularly large particle sizes in a two-wheeled food extrusion molding machine in which twin screws rotate in the same direction.

Twin-screw food extrusion molding machines have received a lot of attention in recent years because they can use any material as an ingredient for sweets and other foods, regardless of the viscosity, expansion rate, shape, etc. of the raw materials used. ing.

However, even in this twin-screw food extrusion molding machine,
Particularly in machines where the twin screws rotate in the same direction, the disadvantage is that even if raw materials with large particle sizes, such as dies or corn, are fed directly to the twin screw molding section, they will not penetrate the twin screws. was there.

This invention eliminates the drawbacks of the above conventional example,
The purpose of this is to provide an indentation section for the raw material in front of the biaxial forming section that performs a series of processes such as kneading, heating, and pressurization, and the raw material passes through this indentation section before being sent to the biaxial forming section. The present invention is intended to propose a method for feeding raw materials in a twin-screw food extrusion molding machine in which even raw materials with large particle sizes can be easily penetrated into the twin-screws.

Hereinafter, according to an example of an apparatus used for carrying out this invention,
This invention will be explained in detail.

(1) is a two-wheeled food extrusion molding machine in which a biting part (2) and a biaxial molding part (3) are arranged in an intersecting manner. (See Figure 1) Two-wheeled screws (4) (4') are installed in parallel on the biting part (2), and has a hopper (5) for inputting raw materials. ') is driven by the drive motor (7) via the speed reducer (6) as shown by the arrows a and a in the figure.
Rotate inward in the opposite direction as shown in '. The biaxial forming section (3) is arranged in an intersecting manner so as to communicate with the discharge port (8) of the biting section (2), and a kneading section (A), a heating section (B), and a pressurizing section (C) are formed respectively. The twin screws (9) (/9) are installed in parallel and have an outlet (10) for extruding confectionery and other food products or semi-finished products.
) (9') is connected to the drive motor (1) via the reduction gear (11).
2), the arrows in the figure rotate in the same direction. In addition, what is shown in Fig. 2 and Fig. 3 has a biting part (
This is an example in which 2) is provided on the upper part of the biaxial molding part (3),
In the case shown in Fig. 2, the biting part (2) and the biaxially formed part (3) are arranged in opposite directions, and in the case shown in Fig. 3,
The biting part (2) and the biaxial forming part (3) are arranged in the same direction.

Therefore, when raw materials with a large particle size such as dice or corn are inputted from the hopper (5), they are transferred to the two-wheeled screw (4) (4') which rotates inward in the opposite direction as shown by the arrows a and a' in the figure. It digs into the part (
2) It is finely pulverized while passing through step 2). The finely pulverized raw materials are then extruded into the twin-screw molding section (3), bit into the twin-screws (9) and (a) rotating in the same direction as indicated by arrows S and B' in the figure, and then passed through the kneading section (A). ), heating section (
B) and pressurizing section (C), the raw materials are kneaded, heated, pressurized, and extruded from the extrusion port (lO), and at that moment the raw materials are released from the pressurized state and expand into a foam, forming a product or semi-finished product. Commercialized.

That is, according to the method of the present invention, even raw materials with a large particle size are finely pulverized in the biting part (2) in advance, so that the twin screws (9) rotating in the same direction of the two-shaft forming part (3) <! 1′>, the raw material also easily penetrates.

As described above, according to the method of the present invention, even when raw materials with large particle size are used as food materials such as sweets, they can penetrate well into the twin screws,
Foods can be manufactured efficiently.
