[Detailed Description of the Invention] "Technical Field" The present invention relates to a food extrusion molding apparatus that is applied, for example, to the production of fish paste products.

"Prior Art and its Problems" In the production of fish paste products such as kamaboko, fish paste is molded using an extrusion molding device.

Conventionally, this type of extrusion molding apparatus has, for example, a third
As shown in the figure, a hopper 12 for feeding food materials is installed on a base 11, and the food materials fed to the hopper 12 are pumped by a raw material supply pump 13 through a transfer pipe 14 to an extrusion molding device main body 15. It's becoming like that. The food material is extruded into a predetermined shape from the nozzle 16 of the extrusion molding device main body 15, and cut into a predetermined length by a cutter or the like (not shown).

However, products produced by molding a single food material using the extrusion molding apparatus have a monotonous texture and appearance, and are rather lacking in taste. Therefore, the nozzle is made into a multi-tube structure to simultaneously extrude and mold a plurality of food materials of different materials and colors.

As one attempt, Special Publication No. 56-38189,
In Japanese Patent Publication No. 58-29067, a cylindrical nozzle is made into a multi-tube structure, and an annular discharge port is formed on the periphery of the nozzle.
This annular discharge port is further divided into circular arcs, and coating materials of different colors are simultaneously extruded from each arc-shaped portion, and the nozzle is rotated to create a spiral pattern on the surface. is proposed.

According to the above-mentioned device, a novel pattern consisting of spiral stripes of different colors can be applied to the surface, but the structure of the device becomes complicated, the manufacturing cost increases, and maintenance such as internal cleaning is difficult. There was a problem.

"Purpose of the invention" An object of the invention is to provide an extrusion molding apparatus for food that has a simple structure and is capable of forming a spiral or other pattern on the outer periphery.

"Structure of the invention" The food extrusion molding apparatus according to the invention has a rotary tube attached to the tip of an extrusion nozzle for extruding food materials, and an introduction hole through which another food material is introduced on the outer periphery of the rotary tube. The invention is characterized in that a fixing tube that covers the introduction hole to form an annular space is attached thereto, and an introduction part for introducing another food material into the annular space of the fixing tube is provided.

Therefore, by extruding the food material from inside the nozzle and introducing food materials of different colors from the introduction part of the fixed cylinder while rotating the rotary cylinder, it is possible to add a spiral pattern of different colors to the outer periphery. can. In addition, by variously changing the rotation of the rotary cylinder,
It is also possible to provide not only a spiral pattern but also other shapes such as a wave pattern. Further, since the conventional extrusion molding apparatus only needs to be provided with a rotary cylinder and a fixed cylinder, the structure is simple, manufacturing costs are low, and maintenance such as cleaning is also easy.

"Embodiment of the invention" FIGS. 1 and 2 show an embodiment of the extrusion molding apparatus for food according to the invention.

In this extrusion molding device 21, a fluid introduction pipe 23 such as water is arranged in the center of a cylindrical nozzle 22. The cylindrical nozzle 22 is bent into an L-shape at the rear, and a fluid introduction pipe 23 projects rearward from this bent portion. For example, white ground fish meat A is introduced into the cylindrical nozzle 22, and hot water B, etc., is introduced into the fluid introduction pipe 23.

A bearing 24 is provided at the tip of the cylindrical nozzle 22.
A rotary tube 25 is rotatably mounted via the rotary cylinder 25. A pulley 26 is formed on the outer periphery of the rotating cylinder 25, and this pulley 26 is connected via a drive belt 29 to a pulley 28 attached to a drive shaft of a motor 27. Therefore, the rotary cylinder 25 is rotated by the operation of the motor 27.

An introduction hole 30 for introducing another food material, for example, lean fish paste C, is formed in a part of the rotary cylinder 25. A fixed cylinder 32 is attached to the outer periphery of the rotary cylinder 25 via a bearing 33 so as to cover the introduction hole 30 and form an annular space 31 between the rotary cylinder 25 and the rotary cylinder 25 . Therefore,
When the rotary cylinder 25 rotates, the introduction hole 30 rotates along the annular space 31. Fixed tube 32
An introduction part 34 for introducing, for example, lean minced fish meat C into the annular space 31 is formed. Note that a plurality of introduction holes 30 may be provided along the circumferential direction.

Further, the distal end of the rotary cylinder 25 forms a discharge port 35, and the distal end of the fluid introduction tube 23 described above extends to the vicinity of the discharge port 35.

Next, an extrusion molding operation using this extrusion molding device 21 will be explained.

First, white ground fish meat A is force-fed into the cylindrical nozzle 22. At the same time, hot water B is introduced into fluid introduction pipe 2.
It will be introduced within 3. On the other hand, lean fish meat C is introduced into the annular space 31 of the fixed cylinder 32 through the introduction part 34. At the same time, the motor 27 is activated to rotate the rotary cylinder 25 via the pulley 28, drive belt 29, and pulley 26.

The white fish meat paste A is formed into a cylindrical shape through the gap between the cylindrical nozzle 22 and the fluid introduction pipe 23, and is extruded from the discharge port 35 of the rotating cylinder 25. In this case, the cylindrical molded product is heated by the hot water B flowing in the fluid introduction pipe 23, and the inner wall is solidified to some extent, so that the cylindrical shape can be maintained without the inner wall becoming sagging. In addition, boiling water B is
After the molded product is extruded, the liquid flows through the inside of the molded product and flows out from the tip (appropriately cut end face) of the molded product.

On the other hand, lean fish meat C is introduced into the annular space 31 through the introduction part 34 of the fixed cylinder 32,
The introduction hole 30 on the outer periphery of the rotating cylinder 25 is press-fitted, and the white minced fish meat A is attached to the outer periphery. In this case, since the rotary cylinder 25 is rotated by the motor 27,
The position of the introduction hole 30 is also rotated, and as a result, the red minced fish meat C forms a spiral stripe and adheres to the outer periphery of the white minced fish meat A.

In this way, it is possible to obtain a molded product which has a cylindrical shape as a whole and has red meat ground fish C adhered to the outer periphery of white meat ground fish A in a spiral manner. The molded product extruded from the discharge port 35 of the rotary cylinder 25 is cut into appropriate lengths by a cutter (not shown) as needed, and the entire molded product is heated and solidified by immersion in hot water or the like. Note that the heating may be performed by steaming, microwaves, frying, or the like. When using oil, it is preferable to use heated oil as the fluid introduced into the fluid introduction pipe 23.

By the way, in the above-mentioned extrusion molding apparatus 21, if the rotary cylinder 25 is swung so as to change the direction of rotation at a predetermined angle, the lean fish meat C can be formed into a wavy pattern. Others, rotating cylinder 2
By changing the rotation mode of 5, various patterns can be formed.

In the above embodiment, the rotary cylinder 25 may have two or more introduction holes 30. In that case, the lean fish meat C is introduced from each introduction hole 30, and the parallel striped pattern is spirally formed. , waveform, etc. In addition, two or more introduction holes 30 of the rotary cylinder 25 may be provided axially apart, and a plurality of fixed cylinders 32 may be mounted in correspondence with each introduction hole 30. In this case, each fixed cylinder By changing the colors of the food materials introduced into 32, it is possible to obtain a molded product having patterns of multiple colors.

In the above embodiment, the cylindrical nozzle 2
Although a fluid introduction pipe 23 is disposed in the cylindrical nozzle 2, the fluid introduction pipe 23 may be omitted. In that case, the white fish paste A introduced into the cylindrical nozzle 22 will be formed into a cylindrical shape. In this case, the cylindrical nozzle 22 may be a double cylindrical nozzle, and another fish paste may be introduced into the center.

Furthermore, by changing the introduction pressure of the lean fish minced meat C into the annular space 31 formed between the fixed cylinder 32 and the rotating cylinder 25 and changing the extrusion pressure from the introduction hole 30, the lean fish meat minced meat C can be prepared. It is also possible to change the thickness of the patterned portion by C.

Furthermore, as shown by the imaginary line in Figure 2,
A ring 36 protruding inward may be provided on the inner periphery of the rotating cylinder 25 in a portion in front of the introduction hole 30.
This ring 36 also allows the red meat minced fish C to be easily introduced into the outer periphery of the white minced fish meat A from the introduction port 30.

It is also possible to cover the discharge port 35 with a casing made of an edible film and fill the extruded food material into the casing.

``Effects of the invention'' As explained above, according to the invention, various patterns such as spirals and waves can be applied with a simple structure in which a rotating cylinder and a fixed cylinder are attached to the tip of the nozzle. can. Also, since the structure is simple,
Maintenance such as cleaning is also easy.
