[Explanation of Examples]

Hereinafter, the present invention will be described in detail based on the drawings. FIG. 1 is a perspective view showing an embodiment of the eleventh and second inventions;
FIG. 2 is a partially sectional side view showing an enlarged view of the main parts in FIG. 1.

For convenience of explanation, first, a raw material supply device in a food extruder according to the second invention will be explained. This raw material supply device (hereinafter simply referred to as the device) 1 consists of a main body, a hopper 2, a belt conveyor 3 as a loading member, a weighing loading device 4, and two rolls 5 and 6 provided in the middle of the hopper 2. It is composed.

The hopper 2 includes a first hopper 2a and a second hopper 2b, and is a food extruder (hereinafter simply referred to as an extruder).

) The supply port 2c of the second hopper 2b is connected and fixed to the raw material supply section 9 provided in the feeder section 8 of 7, and the first
A hopper 2a is provided. The first hopper 2a is
In addition to having an input port 12 for raw materials 11 and 18 on the upper part,
A supply pipe 13 for supplying water and liquid additives to the interior is installed at an intermediate position, and a belt conveyor 3 for carrying raw materials 11 faces the input port 12.

The belt conveyor 3 serves as a loading means for conveying and feeding raw materials 11 in solid form, such as fish as shown in the figure, or vegetables, etc. It's okay.

The weighing and loading device 4 includes a small hopper 14 and a belt conveyor 15.
, a feeder 16 having a star-shaped cross section, and a motor 17 for driving this feeder 16.

The feeder 16 feeds a predetermined amount of raw material 18 such as powder or granules into each recess 16a from the input port 14a of small pieces < 14, and sequentially feeds each recess 16a by rotation by a motor 17. It is dropped onto the belt conveyor 15 and placed thereon. The motor 17 rotates the feeder 16 intermittently or continuously in accordance with the type and amount of the raw material 11, such as solid material. For this reason, the supply of the raw material 18 to the hot spring 2 can be freely adjusted. As the raw material 18, there are various possible materials such as wheat flour, bread crumbs, etc. which are in a solid form corresponding to the raw material 11, a mixture thereof, a kneaded product, etc. Further, as the weighing/carrying-in device, devices other than the illustrated example may be used.

The rolls 5 and 6 are interposed between the lower discharge port 19 of the first hopper 2a and the upper opening 10 of the second hopper 2b, and receive the raw materials 11 and 18 supplied from the first hopper 2a. , these are mixed between both rolls 5°6 and crushed and crushed to a size that can be fed to the extruder 7.

Both rolls 5.6 are rotated by a drive source (not shown) at different circumferential speeds, specifically different angular velocities, so that a gap is created between the two rolls 5.6, and the rolls rotate at low speed. The roll 5 on the side where the material is wound is used for winding up the raw material υ. This is because the mixed raw material A, which has been mixed, crushed, and crushed between the rolls 5 and 6 and has become a paste, is mostly attached to the roll 5 on the low speed side due to the gap between both rolls 5 and 6, and is attached to the roll 5 on the high speed side. This method takes advantage of the fact that it does not stick to the surface.

The high-speed roll 6 is equipped with a driving means 20 such as an air cylinder, and can move forward and backward in the direction of arrow X in the figure, so that the contact pressure with the low-speed roll 5 can be adjusted. For this reason, raw material 11.

The size of crushing and crushing of the solid raw material 11 by the rolls 5 and 6 can be freely adjusted according to the performance of the extruder 18 and the extruder 7.

A raw material cutting knife 22 is mounted on a ball screw 21 below the roll 5 on the low speed side.

The ball screw 21 is disposed along the longitudinal direction of the roll 5 (arrow Y direction in the figure), and the motor rotates the ball screw 21 to move the raw material cutting knife 22. The raw material cutting knife 22 consists of a base body 24 attached to the ball screw 21, an air cylinder 25 provided on the base body 24, and a knife 26 attached to the tip of this air cylinder 25 (14 knives). 26 moves toward and away from the roll 5 as the air cylinder 25 advances and retreats (in the two directions indicated by arrows in the figure).The mixed raw material A wound around the roll 5 is rolled from the roll 5 into a belt shape by the knife 26. The mixed raw material A cut from the roll 5 is fed into the feeder section 8 of the extruder 7 through the upper opening 10 of the second hopper 2b and into the feeder section 8 of the extruder 7. The distance between the surface of the roll 5 and the knife 26 is adjusted depending on the performance of the machine 7 and the like.

The roll 5 is equipped with a spatula member 27 near the top for adjusting the winding thickness t of the mixed raw material A. This spatula member 27 has a spatula 29 attached to the tip of the air cylinder.
The air cylinder 28 is driven according to the state in which the mixed raw material A is wrapped around the roll 5 and the state in which it is cut by the knife 26, and the mixed raw material A is scraped off from the roll 5 to adjust the rolled thickness t to rA. . The mixed raw material A that has been scraped off is again supplied between the rolls 5 and 6 to be scraped.

The extruder 7vi is used to knead the mixed raw material A supplied by a screw (not shown) in the feeder section 8, and is capable of heating, cooling, tasting, dehydration, drying, etc. depending on the product. do it. At the tip of the feeder section 8, the mixed raw material A is extruded into a predetermined extrusion form (for example, a rondo shape such as fishballs or kamaboko, a pipe shape such as a bamboo ring, a powdery shape such as furikake or bed food, or a small diameter rod shape). ] The die 30 is molded according to the mounting method.

Next, a method for supplying raw materials in extrusion for food products, which is the first invention, will be explained. First, the amount of raw material 11 in solid form to be processed at one time is placed on the belt conveyor 3, and
A raw material 18 such as powder or granules is charged into the small hopper 14 of the weighing/carrying device 4 in the required amount. This color roll 5,
6 is rotated in advance at a rotation speed depending on the properties and quality of the raw material 11. However, the rotational speed of the roll 5 is set to be lower than the rotational speed of the roll 6. Further, the rolls 5 and 6 are rotated in contact with each other when the raw materials 11 and 18 are first introduced, so that slippage occurs between the two rolls 5 and 6 due to the difference in peripheral speed.

Next, both belt conveyors 3 and 15 are started, and the raw material 11
, 18 are introduced into the first hopper 2a from the input port 12. In the illustrated example, a powdered raw material 18 is intermittently fed into the first hopper 2a in accordance with the amount of fish as the raw material 11.

Here, when both raw materials 11 and 18 are put into the first hopper 2a, both raw materials 11 and 18 are fed from the supply pipe 13 as necessary.

That is, the raw material 1 drawn between the inner rolls 5 and 6
The raw material 11 is crushed by contact rotation between the two rolls 5 and 6, and the crushed raw material 11 is crushed by the sliding between the inner rolls 5 and 6, and the raw materials 11 and 18 are further mixed to have uniform properties. Make a paste-like mixed raw material.

The paste-like mixed raw material A is rubbed by the high-speed rotation side roll 6 against the low-speed rotation side roll 5, and the paste-like mixed raw material E1. Form layer A. At this time, the drive means 20 attached to the roll 6 is activated to cause the roll 6 to be effortlessly separated from the roll 5.
The gap between the rolls 5 and 60 is widened to form a layer of mixed raw material A evenly on the surface of the roll 5.

After forming a layer of the mixed raw material A to a predetermined thickness on the surface of the roll 5, the spatula 29 is brought close to the roll 5 by the operation of the air cylinder 28, and the mixed raw material A wound on the roll 5 is scraped off. , the winding thickness t is kept constant. The scraped mixed raw material A is rolled up between the re-rolls 5 and 6 and crushed, thereby eliminating variations in properties and further increasing uniformity. In addition, the thickness t of the winding sheet for scraping off the mixed raw material A with the spatula 23
shall be determined according to the 110 types of raw materials.
