Description

Detailed Description of the Invention

The present invention relates to a scouring machine that sews food ingredients such as chestnuts and sweet potatoes and separates them into actual paste components and skin (residue).

Food ingredients such as chestnuts and sweet potatoes are used in Japanese confectionery and Western confectionery after being crushed in a paste form by a back squeezing machine. A food disintegrating machine described in Japanese Utility Model Publication No. 63-66598 is known as a machine for backing food ingredients.
The food disintegrating machine described in this publication is provided with a food raw material inlet at one end of a cylindrical casing with a helical screw and a perforated plate having a number of holes at the other end. A pressing blade and a separation blade that rotate together with the screw are attached to the front end of the screw that is housed in the housing. While feeding the food raw material introduced from the inlet to the front end of the casing with a screw, stirring with the press blade attached to the front end of the screw, while scraping off the food raw material fixed to the inner surface of the porous plate with the peeling blade It was designed to be lined up.

  Shokai 63-66598

In this food disintegrator, the food that has been put into the hopper is pumped by the screw and then stirred by the pressure blade, so that the food is gradually tightened tightly and lacks a soft feeling or becomes sticky and lacks the flavor. There was a problem. In particular, when the food raw material is chestnut, when it is pumped by a screw and rubbed, the stickiness becomes strong, and the flavor is lowered by the heat generated by friction, which is not suitable for Japanese sweets that value the flavor. Moreover, when the skin mixed in the food material is larger than the hole diameter of the perforated plate, there is a drawback that clogging occurs inside the perforated plate and the load on the machine increases. Even if the food material adhered to the inner surface of the perforated plate is scraped off by the peeling blade, the skin larger than the holes of the perforated plate cannot be discharged, and clogging cannot be prevented.
In order to remove the clogged skin, the machine had to be stopped and disassembled, and the internal cleaning had to be taken care of.

The present invention has been made to solve the above-mentioned problems, and keeps the flavor of food by minimizing frictional heat generated in the back, and the food material mixed with the skin is also made of the actual paste and skin ( It is an object of the present invention to provide a machine that can be easily separated from the residue (residue) and that can easily remove the skin (residue) and clean the machine.

In order to achieve the above object, in the present invention,
1. A cylindrical lining drum having a large number of through holes on the outer peripheral surface is attached so that the axis of the disc-shaped rear flange and the disc-shaped front flange coincide with the drive shaft.
2. The drive shaft is supported by tilting the shaft center forward and downward so that the front flange is horizontal or slightly below the rear flange in the frame constituting the backside machine, and in conjunction with the motor of the drive source. Is provided.
3. A pressing roller having an axis parallel to the back drum and having an elastic layer formed on the outer peripheral surface thereof is rotatable, and the outer peripheral surface is provided so as to be movable toward and away from the back drum.
4). A food material inlet is provided above the circumscribed portion of the back drum and the pressure roller, enabling the food material to be input.
5. A scraper for scraping off the skin (residue) attached to the outer peripheral surface of the back drum is provided close to the back drum.
6). The rear flange has a plurality of guide pins projecting forward from the outer peripheral portion toward the front flange in the circumferential direction.
7). The front flange is provided with a plurality of pin holes through which the guide pins are inserted in the circumferential direction in the outer peripheral portion, and an opening for discharging the backed actual paste.
8). The back drum is fitted to the outside of the guide pin of the rear flange attached to the drive shaft.
9. The front flange is detachably attached to the drive shaft so that its pin hole matches the guide pin of the rear flange.
10. A back drum is held between the rear flange and the front flange.
11. A non-metallic tube made of plastic, rubber, or the like is attached to the guide pin, and the tube and the inner surface of the back drum are in contact with each other.
When a food material in a state where the fruit and the skin are mixed is continuously input from the input port manually or by a conveyor or the like, the food material falls on the back drum and the pressure roller. The back drum is driven by a motor and rotates in a certain direction. The rotation direction is a direction in which the food material is sandwiched between the back drum and the pressing roller and crushed. The pressure roller circumscribes the back drum and rotates in the opposite direction to the back drum.
The clearance between the back drum and the pressure roller is set to 0 mm to several millimeters. When the clearance is 0 mm, the outer peripheral surface of both is only in contact, and the pressure roller is fixed to the back drum. It may be pressed by the pressure. Since the pressing roller is provided so as to be movable toward and away from the back drum, the gap is set according to conditions such as the type and hardness of the food material.
The food material put on the back drum and the pressure roller is gradually sandwiched and crushed while the elastic body layer of the pressure roller is recessed with the rotation of the back drum and the pressure roller. The crushed food raw material is separated from the skin to form an actual paste, which is pushed inward through the through-hole of the back drum. The skin larger than the hole diameter of the through hole cannot pass through the through hole and is separated from the actual paste, and remains attached to the outer peripheral surface of the back drum. This skin is scraped off by a scraper that is in close contact with the outer peripheral surface when the rotation of the back drum advances half a round. The scraper is generally made of a highly wear-resistant plastic and adopts a straight plate shape, but is not limited thereto. The scraper is almost in contact with the outer peripheral surface of the back drum by spring force. A container for residue is disposed below the scraper.
When the back drum is supported horizontally, the actual paste accumulated inside stops the operation of the machine and scrapes it from the opening formed in the front flange, or removes the front flange from the drive shaft, and the back drum Remove and scrape from inside.
In the case where the back drum is supported while being inclined downward, it is discharged from the opening formed in the front flange as the actual paste is deposited inside the back drum.
Since the skin (residue) still adheres to the back drum, in order to increase the yield of the back scrubbing drum, a plurality of pressing rollers are provided on the outside of the back drum to which the skin (residue) is attached. It is also possible to take out the fruit contained in the residue as a paste. This roller may be harder than the elastic body layer of the first pressing roller described above, or may be made of metal or hard plastic.
The non-metallic tube made of plastic or rubber attached to the guide pin prevents the metal back drum and the metal guide pin from coming into direct contact with each other. Prevent occurrence.

By adopting the above configuration, the actual paste is crushed and lined, and unlike the conventional case where the actual paste is stirred and lined, there is no tightness by pressure feeding or stirring, and no heat is generated.
Therefore, there is no tight tightening or quality degradation due to heat. The skin (residue) can be easily separated without impairing the quality of the food material, and the skin (residue) adheres to the outer peripheral surface of the back drum, so that removal with a scraper becomes easy. Since the food material is sandwiched between the squeezing drum and the pressure roller and crushed while being gradually crushed, it is difficult to get sticky and an actual paste excellent in fluffy taste is obtained.
