Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for producing a nodular coated food product in which a solid food material is coated with multiple types of plastic food materials in multiple layers;
For more details, please refer to dough, gyuhi mochi, candy, and the equipment.
While molding plastic food materials such as meat, minced meat, and matsushi potatoes into a plurality of nodules, one or more solid food materials such as chestnuts, strawberries, nuts, boiled eggs, diced meat, etc. are simultaneously placed inside. The present invention relates to a new method that enables continuous mass production through encapsulation, and an apparatus therefor, and is extremely useful, for example, in the confectionery industry and the processed food industry.

[Conventional technology and technical issues to be solved]

Conventionally, coated confections and coated processed foods that contain solid substances, such as chestnut buns made by covering chestnuts with confectionery dough, strawberry jelly made by covering strawberries with jelly, or "bakudan" made by covering boiled eggs with minced fish, have traditionally been processed by machines. The reality is that there is no effective method or equipment that allows for continuous production, and manufacturing is done exclusively by hand, which takes a lot of time and effort. The need arose.

Under these circumstances, the present inventor once extruded a plastic food material from an extrusion die into a tube shape, and provided a solid material guide tube smaller than the extrusion inner diameter in the center of the extrusion die. The solid food material is inserted at required intervals into the hollow part of the tube-shaped plastic food material, and the tube-shaped plastic food material into which the solid food material has been inserted is cut into the hollow part and rolled to form a lump. We first proposed a spherical cutting device for manufacturing coated foods (Special Publication Act 1986-
No. 34781), it paved the way for the mechanical mass production of nodule-shaped coated foods containing solids, which could previously only be produced by hand.

However, when such a spherical cutting device is used, depending on the physical properties of the plastic food material to be processed, it may not only contain solid food materials but also contain air, and this air cannot escape. As a result, the encapsulated solid food material and the plastic food material do not adhere to each other and tend to separate easily, resulting in a reduction in commercial value.

Therefore, one object of the present invention is to provide a nodule-shaped coated food product that has extremely good adhesion between the solid food material contained therein and the several types of plastic food materials that cover it in multiple layers, so that there is no risk of peeling. An object of the present invention is to provide a manufacturing method and an apparatus for the same.

Another object of the present invention is to provide a manufacturing method and apparatus capable of coating a solid food material with multiple types of plastic food materials in multiple layers to form a nodule-shaped coated food without enclosing any air at all. It is to be.

Still another object of the present invention is to provide an apparatus for producing a multi-layer nodule-shaped coated food that automatically contains solid food materials without touching the solid food materials and plastic food materials.

Still another object of the present invention is to provide a manufacturing method and apparatus that can efficiently and hygienically manufacture multi-layered nodule-shaped coated foods containing solid food materials with almost no coating errors. .

Still another object of the present invention is to provide a method and apparatus for manufacturing a multi-layer nodular coated food product in which a solid food material is coated with several types of plastic food materials.

Further objects and advantages of the invention will become apparent from the following detailed description of the invention.

[Technical means adopted to achieve the objective]

That is, the present invention relates to a method and apparatus for manufacturing a nodular coated food product in which a solid food material is multi-layered coated with a plurality of types of plastic food materials, and a device for manufacturing the same. The food material is prepared in the form of a multi-layer bottomed cylinder, and the solid food material is introduced into the bottom of the plastic food material prepared in the multi-layered bottomed cylinder. Thereafter, by opening the gate, the plastic food material in the multi-layer bottomed cylindrical shape into which the solid food material has been introduced is forced out downward into a lump shape, and the plasticity of the material lump that has been pushed out is The gist lies in the interconnection of the process of cutting the neck portion of the food material to obtain a nodule-shaped coated food product formed into a nodule shape, and the technical means for carrying out the process.

In the illustrated first to third embodiments, the push piston 5
A cover 51a made of non-adhesive resin (silicone rubber, fluororesin) is attached to the tip of the cover 1 to prevent materials from adhering to it. However, this cover 51a is not essential, and the tip of the piston 51 may be coated with fluorine resin to prevent the adhesion of plastic food materials (for example, sticky gyuhi mochi material, etc.). Can be done.
