Description

[Detailed Description of the Invention] [Industrial Application Field] The invention of this application relates to an extrusion manufacturing apparatus for foods that do not require foaming, such as pasted foods and egg rolls.

[Conventional technology]

Conventional food extrusion manufacturing equipment has one or more screws installed inside the cylinder, and the rotation of these screws performs processes such as heating and pressurizing while kneading food materials. There is one that is extruded from a nozzle.

The food extrusion manufacturing apparatus described above is particularly suitable for manufacturing foamed foods containing all grains such as rice, beans, and corn.

[Problem that the invention seeks to solve]

However, it is unsuitable for producing dough foods such as chikuwa, kamaboko, ham, and sausage, and foods that do not require foaming, such as tamagoyaki.

Therefore, the object of the present invention is to provide a food extrusion manufacturing apparatus that prevents foaming in order to manufacture foods that do not require foaming.

[Means for solving problems]

Therefore, in the invention of this application, the food materials put into the cylinder are kneaded, heated and pressurized,
An apparatus for producing food by extruding it from a discharge nozzle, wherein the cylinder is composed of an inner cylinder and an outer cylinder, the outer cylinder is provided outside the inner cylinder with a space therebetween, and a temperature control pipe is provided within the space. Furthermore, a liquid supply pipe is provided in the kneading section inside the inner cylinder, a heater is provided outside the outer cylinder, and a cooling unit is provided between the cylinder and the discharge nozzle, and a refrigerant inlet or outlet of the cooling unit is provided. One of the outlets is provided near the cylinder side, the other near the discharge nozzle side, and both are provided facing each other on a substantially diagonal line of the cooling unit.

[Effect]

As a result of applying the above means, the food material can be heated to an appropriate temperature and adjusted to an appropriate viscosity, and then cooled before being sent from inside the cylinder to the discharge nozzle, and then extruded from the discharge nozzle. Food no longer foams.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the invention of this application will be described below with reference to drawings showing one embodiment.

Reference numeral 1 denotes a main body of the food extrusion manufacturing apparatus, and the cylinder is composed of an inner cylinder 5 and an outer cylinder 9, and the food material input from the input section 2 is transferred to the communication section 3.
It is configured to be sent to the kneading section 4 inside the inner cylinder 5 via. This kneading section 4 has a plurality of (two in this embodiment) screws 6 disposed inside an inner cylinder 5, and a communication section 3 of the kneading section 4.
A liquid supply pipe 7 communicating with the outside of the food extrusion manufacturing apparatus main body 1 is provided near the food extrusion manufacturing apparatus main body 1 .

An outer cylinder 9 is provided outside the inner cylinder 5 with an appropriate space 8 in between, and within the space 8 there is a temperature control pipe 10 through which water flows.
is provided. Furthermore, an appropriate heater (not shown) is installed on the outside of the outer cylinder 9, and the heating effect of the heater is applied to the food material in the inner cylinder 5 through the space 8 and the inner cylinder 5. There is. Therefore, the temperature control pipe 10
By adjusting the flow rate of water passing through the inside and the amount of heat of the heater, food materials can be heated to an appropriate temperature very efficiently.

A cooling unit 11 is connected to the front of the inner cylinder 5, and a discharge nozzle 12 is connected to the front of the cooling unit 11. The cooling unit 11 has a communication passage 13 between the inner cylinder 5 and the discharge nozzle 12 inside, and an outer cylinder 15 provided on the outside with an appropriate space 14 in between, and a circulation pipe 16 arranged inside the space 14. , an appropriate refrigerant such as water or low-temperature gas is circulated.
The circulation pipe 16 is provided with one of the refrigerant inlet and outlet near the cylinder side, the other near the discharge nozzle 12 side, and both facing each other on a substantially diagonal line of the cooling unit 11. There is.

Since the food extrusion manufacturing apparatus according to the invention of this application is configured as described above, for example, in order to manufacture kamaboko paste food, fish meat, egg white,
Other seasonings, etc. are added from the input section 2, and the communication section 3
It is sent to the inner cylinder 5 via. These kamaboko materials are kneaded in the inner cylinder 5 by the rotation of a plurality of screws 6. At this time, if necessary, liquid can be sent from the liquid supply pipe 7 to adjust the viscosity of the kamaboko material to an appropriate level. Next, the kamaboko material is heated very efficiently by the temperature control pipe 10 and the heater, and is sent to the communication path 13 of the cooling unit 11 while being pressurized by the extrusion action of the screw 6.
The kamaboko material kneaded, heated, and pressurized in the communication path 13 is cooled to the desired temperature very efficiently inside by the circulating refrigerant in the space 14, and then is discharged from the discharge nozzle 12 into a kamaboko product. Extruded continuously.

〔Effect of the invention〕

As described above, the food extrusion manufacturing device of the invention of this application is provided with a cylinder that performs processes such as kneading, heating, and pressurization very efficiently, and a discharge nozzle that cools the inside of the food material very efficiently. Since the food material is kneaded, heated, and pressurized, it is completely cooled down to the inside and no longer foams before it is sent from the cylinder to the discharge nozzle. It has the effect of being optimal for the production of foods that do not require.
