The roll 5.6 is connected to the discharge port [4] at the bottom of the first hopper 2.
It is interposed between the upper opening IO of the second hopper 3,
The raw material 11 that has passed through the first hopper 2 is received, and the raw material 11 is crushed and crushed between the inner rolls 5 and 6 to a size that can be supplied to the extruder 7.

Both rolls 5 and 6 are rotated at different circumferential speeds, specifically different angular velocities, by a drive source (not shown), and the inner rolls 5 and 6
A gap is created in between, and the roll 5 rotating at low speed is used for winding up the raw material. This is roll 5
, 6, the raw material 11a that has been crushed and crushed into a so-called paste-like state mostly adheres to the low-speed roll 5 due to the slip between the inner rolls 5 and 6, and does not adhere to the high-speed roll 6. It has become.

The high-speed roll 6 is equipped with a driving means 15 such as an air cylinder, and is movable forward and backward in the direction of arrow X in the figure, so that the contact pressure between it and the low-speed roll 5 can be adjusted. Therefore, the size of the crushing and crushing of the raw material 11 by the rolls 5.6 can be freely adjusted according to the performance of the raw material 11 and the extruder 7.

A raw material cutting knife 17 is mounted on a ball screw 16 below the roll 5 on the low speed side.

A ball screw 6 is disposed along the longitudinal direction of the roll 5 (in the direction of the arrow Y in the figure), and is configured to rotate the grain screw 16 by a motor 18 so that the raw material cutting knife 17 can be moved. The raw material cutting knife 17 is composed of a base body 18a attached to the ball screw 6, a machining cylinder 18b provided on the base body 18a, and a knife 20 attached to the tip of the air cylinder 18b. The knife 20 moves toward and away from the roll 5 as the air cylinder 18b moves back and forth (in the two directions indicated by arrows in the figure). Paste raw material 11 wrapped around roll 5
a is cut into a belt shape from the roll 5 by the knife 20, passes through the second hopper 3 through the upper opening 10 of the second hopper 3, and is fed into the feeder section 8 of the extruder 7. The thickness of the raw material 11a cut from the roll 5 is
The distance between the surface of the roll 5 and the knife 20 may be adjusted depending on the performance of the extruder 7 and the like.

The roll 5 is equipped with a spatula member 21 near the top for adjusting the winding thickness L of the raw material 11a. This spatula member 21
The air cylinder 22 is equipped with a spatula 23 at the tip of the air cylinder 22, and the air cylinder 22 is driven according to the state in which the raw material 11a is wrapped around the roll 5 and the state in which the raw material 11a is cut off by the knife 20, and the raw material is removed from the roll 5. 11a is removed to adjust the winding thickness t. The scraped raw material 11a is again fed between the rolls 5 and 6 and crushed.

The extruder 7 kneads the raw material 11a supplied by a screw (not shown) in the feeder section 8, and may be one that can perform heating, cooling, seasoning, dehydration, drying, etc. depending on the product. Further, at the tip of the feeder section 8, the kneaded raw material 11a is extruded in a predetermined extrusion form [for example, a rondo shape such as fish balls or kamaboko, a pipe shape such as a bamboo ring, a powder granule or a small diameter rondo shape such as fushikake or pet food. ] The die used to form the product is attached.

Next, a method for supplying raw materials in the food extruder according to the first invention will be explained. First, the amount of raw material 11 equivalent to one time of processing is placed on the belt conveyor 13, and the Ml of the hopper 4 is loaded.
The hopper 2 is charged into the apparatus 1 through the input port 12 at the top thereof. At this time, the roll 5.6 determines the properties of the raw material 11, t! J
Rotate at a speed corresponding to iw. However, the rotation speed of the roll 5 is set lower than the rotation speed of the roll 6. Further, the rolls 5 and 6 are rotated in contact with each other when the raw material 11 is initially introduced, and a gap is created between the inner rolls 5 and 6 due to the difference in circumferential speed.

The raw material 11 discharged onto the roll 5.6 from the discharge port 14 at the bottom of the first hopper 2 is driven by its rotation on the roll 5.6, and is sequentially driven by both rolls 5.6. It is pulled in, crushed by contact pressure, and then crushed. That is, the raw material 11 drawn between both rolls 5 and 6 is pulverized by the contact rotation of both rolls 5 and 6, and while being pulverized, the inner roll 5,
Crush the pulverized raw material 11 with a 6-space plate,
A paste-like raw material 11a with uniform properties is used.

The paste-like raw material 11a is rubbed by the roll 6 on the ^ speed rotation side against the roll 5 on the low-speed rotation side, and the JM of the paste-like raw material 1.1a is formed on the surface of the roll 50.
will continue to form. At this time, the driving means 1 attached to the roll 6
5 is operated to gradually separate the roll 6 from the roll 5, widening the gap between the rolls 5 and 6, and forming the stain of the raw material 11a evenly on the surface of the roll 5.

After forming a layer of the raw material 11a to a predetermined thickness on the surface of the roll 5, a spatula n is brought close to the roll 5 by the operation of the air cylinder 22, and the raw material 11a wound on the roll 5 is scraped off, and the material 11a wound on the roll 5 is removed. Keep the thickness t constant. Scraped raw material 1
1a is rolled up again between both rolls 5.6 and crushed, eliminating variations in properties and further increasing uniformity. still,
The winding thickness t for scraping the raw material 11a with the spatula 23 is determined depending on the type of raw material 110.

- After pulverizing and crushing all the raw materials 11 input into the process and winding them around the roll 5 as a paste-like raw material 11a,
The air cylinder 18b of the raw material cutting knife 17 is driven to bite the knife 20 into the layer of the raw material 11a wound up on the roll 5. Then, in this state, the knife 20 is moved in the longitudinal direction Y of the roll 5, and the raw material 11 is moved from the roll 5 to the raw material 11.
Cut 9 into a belt shape from a, and open the upper opening I of the second hopper 3.
Cure from O into the second chamber 3. However, raw material 11
Depending on the type of
Cutting by 0 may also be performed.

The raw material IJa that has entered the second hopper 3 is transferred from the supply port 3a to the feeder section 8 via the raw material supply section 9 of the extruder 7.
The wire is mixed with a screw (not shown), subjected to heat treatment, etc., and then extruded from the die 24 in a predetermined form. After the raw material if a wound up on the roll 5 has been completely processed, the raw material 11 is once again introduced into the apparatus 1 from the input port 2 by the belt conveyor 13, and the above-mentioned processing steps are repeated.

In addition, in the above-mentioned method, the raw material 11 is fish meat, which is crushed and crushed until it becomes a paste.
Vegetable protein-based or starch-based raw materials (soybeans, grains, eyelids, etc.) may be used as long as they are crushed or crushed into a form that can be processed by the feeder section 8, and there is no problem in continuously feeding them.
Of course, it may also be crushed or crushed in other conditions.
