The “Food Disintegrator” described in Patent Document 1 is agitated by pressing blades after the food charged into the hopper is pumped by the screw, so that the food is gradually tightened and lacks a soft feeling. There was a problem that it became sticky and lacked in flavor. In particular, when the food ingredient is chestnut, if it is pumped by a screw and squeezed, the stickiness becomes stronger during pumping and stirring, and the flavor drops due to heat generated by friction, making it unsuitable for Japanese sweets that value the flavor. There was a thing. 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 with the peeling blade, the skin larger than the holes of the perforated plate cannot be discharged, and clogging inside cannot be prevented. In order to remove the clogged skin, the machine operation was frequently stopped and disassembled, and it was necessary to take time to clean the inside.

Next, the “food raw material back machine” described in Patent Document 2 was invented as a solution to the problem of Patent Document 1,
A first pressing roller 15 having an elastic layer formed on the outer peripheral surface is rotatable, and the outer peripheral surface is provided so as to be movable toward and away from the back drum 1. Further, the second pressing roller 23 and the third pressing roller 24 are pressed against the back drum 1 with a strong force. The back drum 1 is driven by a motor 12 and rotates in a certain direction, and the first pressing roller 15 does not have a driving source and rotates so as to circumscribe the food drum while sandwiching the food material. The second pressing roller 23 and the third pressing roller 24 do not have a driving source, are directly circumscribed by the back drum 1, and receive a rotational force by the back drum 1.
Since this machine has a structure in which the second and third pressing rollers 23 and 24 are only rotated by being pressed against the backside drum 1, the food material that cannot be completely backwashed by the first pressing roller and adheres to the outer peripheral surface of the backside drum. However, it is difficult to sufficiently recover the remaining real components from the raw materials, the yield of recovering the actual components is poor, and the production efficiency is low.

This invention was made to solve the above-mentioned problems, and keeps the flavor of food by minimizing the frictional heat generated in the lining, and the food ingredients mixed with the skin are also the real ingredients and the skin. It is an object of the present invention to provide a machine that can be easily separated, removes its skin and facilitates cleaning of the machine, and further improves the yield of recovery of the actual components and the production efficiency.

In order to achieve the above object, in the present invention,
1. A drive shaft in which both ends of a cylindrical lining drum having a large number of through holes on the outer peripheral surface are sandwiched between a disc-shaped rear flange and a disc-shaped front flange, and pass through the axis of the rear flange and the front flange. It is supported so that it can rotate freely.
2. The drive shaft is mounted horizontally in the front and rear frames that make up the backside machine, or the backside drum is attached with the front side drum tilted forward and downward so that the front flange is located below the rear flange. The shaft rotates in a predetermined direction in conjunction with the motor.
3. The rear flange is fixed to the drive shaft, and a plurality of guide pins project forward from the outer peripheral portion toward the front flange at equal intervals in the circumferential direction.
4). The front flange is attached so as to be able to rotate integrally with the drive shaft, and a plurality of pin holes through which the guide pins are inserted in the circumferential direction are provided at equal intervals on the outer peripheral portion, and discharges the actual components that are lined up. An opening is provided for this purpose.
5. The front flange is detachably attached to the drive shaft so that its pin hole and the guide pin of the rear flange match, and the back drum is fitted on the outside of the guide pin protruding from the rear flange, The back drum is clamped from both sides by the rear flange and the front flange.
6). 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.
7). By inserting plastic plate spacers between the front flange and the front end of the back drum and between the rear flange and the back end of the back drum, the front flange and the front end of the back drum and the rear flange and the back end of the back drum And are not in direct contact.
8). A first pressing roller having an elastic layer formed on the outer peripheral surface, disposed between the front flange and the rear flange of the back drum, and set to a length shorter than the length of the back drum, and the first press roller An elastic layer is formed on the outer peripheral surface of the lower side of the roller, and is arranged between the front flange and the rear flange of the back drum, and the second pressing roller set to a length shorter than the length of the back drum rotates. The outer peripheral surface is provided so as to be freely contactable and separable from the back drum, and the second pressing roller rotates in a predetermined direction in conjunction with the motor.
9. The first pressing roller rotates as the back drum rotates, and is not linked to the motor. The second pressing roller is linked to the motor of the drive source, and rotates in the opposite direction to the back drum at a speed different from the peripheral speed of the back drum outer peripheral surface, for example, a peripheral speed larger than the peripheral speed of the back drum outer peripheral surface. Is provided.
10. A food material inlet is provided above the circumscribed portion of the back drum and the first pressing roller, enabling the food material to be intermittently or continuously charged.
11. When a food ingredient in which the fruit and skin are integrated, or a food ingredient in which the fruit and skin are mixed, is dropped manually or by a conveyor, etc., from the inlet, the food ingredient is fed from the back drum and the first pressing roller. It falls to the circumscribed part. 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 crushed by being sandwiched between the back drum and the first pressing roller. The first pressing roller rotates with the rotation of the back drum at substantially the same peripheral speed as the back drum. The first pressing roller circumscribes the back drum and rotates in the opposite direction to the back drum. Although the rotation directions at the axis of each other are opposite directions, the traveling direction at the circumscribed portion is the same direction. The clearance between the outer peripheral surface of the back drum and the outer peripheral surface of the first pressing roller is set to a clearance of 0 to several millimeters, and when the clearance is 0 mm, the outer peripheral surfaces of both are only in light contact In some cases, the pressing roller is pressed against the back drum by a certain pressure. Since the first 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, size, and hardness of the food material.
12 The food material dropped on the circumscribed portion of the back drum and the first pressing roller sandwiches the food material with the rotation of the back drum and the first pressing roller. Since the first pressing roller bites the food material and presses it against the back drum while the elastic layer on the outer peripheral surface is recessed, the actual ingredients of the food material are pushed inward as a granular actual paste through the through-hole of the back drum. When the back drum is pressed by the first pressing roller, it is thin and receives a slight deformation force, but the tube fitted to the guide pin absorbs the deformation force to prevent the deformation.
Since the real component is soft and deformable, it can pass through the through-hole, but the skin is larger than the through-hole or hard and difficult to deform, so it cannot pass through the through-hole. Accordingly, the actual component is pushed out to the inside of the lining drum to become an actual paste, and the skin is attached to the outer peripheral surface of the lining drum. The skin to which some real components still adhere rotates with the back drum while adhering to the outer peripheral surface of the back drum.
12 Since the actual component is still attached to the leather attached to the back drum, a second pressure roller is provided at a position advanced approximately 45 ° in the rotation direction from the position of the first pressure roller. The contained real component is further taken out as a real paste.
The second pressing roller is interlocked with the motor, and rotates at a peripheral speed faster than the rotating peripheral speed of the back drum. By making the peripheral speed of the second pressing roller faster than the peripheral speed of the back drum, the actual component adhering to the skin is more efficiently separated.
The skin adhering to the outer peripheral surface of the back drum is moved on the back drum at a faster peripheral speed than the actual component entering the through hole of the back drum. Therefore, a shearing force acts between the real component that has entered the through hole and the skin, and the real component and the skin are separated.
13. The skin is scraped off by a scraper that is in contact with the outer peripheral surface at a further rotated position while adhering to the back drum. 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 the force of a spring or is held in a predetermined gap. A container for putting a leather is disposed below the scraper.
14 The actual paste accumulated in the inside of the back drum is gradually pushed toward the opening as the back drum is rotated, and falls from the opening to the actual container for the actual paste.
The surfaces of the first and second pressing rollers may be made of metal or hard plastic, but are preferably elastic. When the elastic body is recessed, the food material is efficiently sandwiched and rotated.
15. 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. To prevent.
16. When cleaning after the scouring operation, it is necessary to remove the scouring drum to which the food ingredients are attached. Since it is difficult to remove the scraper when it is in elastic contact with the backing drum, a mechanism for separating the scraper from the backing drum is required.
The scraper mechanism of the present plan is such that the scraper is attached in parallel to the shaft center of the back drum at the upper end portion of the three-pronged first lever that is arranged almost upright, and in the middle portion of the lever, the shape is a dogleg shape. The upper end of the formed second lever is rotatably supported by a support shaft, and one end of a spring for elastically contacting the scraper with the back drum is locked to the lower end of the first lever. . The intermediate portion of the second lever is supported by a bracket fixed to the frame by a support shaft, the other end of the spring is locked to the lower end portion, and the lower end portion of the first lever and the lower end portion of the second lever Are designed to attract each other elastically.
In order to fix the lower end portion of the second lever to the frame, a connection fitting called a catch clip is used. This catch clip is equipped with a latch and an operating lever on the clip body. The catch clip is paired with a latch to which the latch is engaged, and the two members are joined tightly by elastically engaging the latch with the latch. The latch and the catch are engaged and released by rotating the operation lever. A catch of the catch clip body is fixed to a stay that connects the front and rear frames, and a catch is fixed to the lower end side of the second lever. When the engagement between the latch and the catch is released, the scraper is separated from the outer peripheral surface of the backing drum. However, when the latch is engaged with the catch and the operation lever is pulled up, the first and second levers are drawn. When the scraper comes into contact with the backside drum, the skin can be scraped off.

By adopting the above configuration, the actual ingredients of the food material are pushed out through the through-holes of the lining drum and rubbed, and unlike the conventional case where the ingredients are crushed by pumping and stirring, the crushed granular real ingredients are firmly tightened. And the quality is improved because less heat is generated.
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.
The actual component that remains without being sufficiently lined only by the first pressure roller is efficiently applied to the real component and the skin by the shearing force generated by the difference in peripheral speed between the second pressure roller and the drum. To be separated. As a result, the yield of actual component recovery is increased.
Since the skin separated from the actual components adheres to the outer peripheral surface of the backside drum, it is easy to remove and discharge with a scraper, eliminating the need to frequently stop the machine to remove the skin, and improve production efficiency.

Embodiments of the present invention will be described below with reference to the drawings shown in FIGS.

The back drum 1 in a back scissor used to back food ingredients with steamed chestnuts, sweet potatoes, pumpkins and other fruits and skins mixed, or mixed with fruit and skin, is rectangular and has a thickness of 1 to 2 A large number of small-diameter through holes 2 processed by a punching machine or the like are formed on a plate material of about millimeters. The diameter of the through-hole 2 is, for example, about 1 mm to 6 mm, and a size that meets the conditions such as the type of food raw material and the use of the actual paste made of the backed actual component is selected. The back drum 1 is formed by rounding a plate material having a large number of through-holes 2 into a circular shape, welding the joint, and forming a hollow cylindrical shape.

The front and rear ends of the opening of the back drum 1 are attached to the drive shaft 5 while being sandwiched between the rear flange 3 and the front flange 4. The rear flange 3 has a disc shape, and a boss portion 3a is formed outward in the center, and an insertion hole 3b for inserting the drive shaft 5 is formed in the boss portion 3a. The rear flange 3 can be fixed to the drive shaft 5 with a bolt 6. In the vicinity of the outer peripheral edge of the rear flange 3, a plurality of screw holes 3c are provided at equal intervals in the circumferential direction, and a plurality of guide pins 7 are screwed vertically into the screw holes 3c toward the front, A tube 8 made of an elastic body is fitted to the guide pin 7. The length of the tube 8 is set slightly shorter than the entire length of the back drum 1.
The back drum 1 is attached to the outside of the tube 8 fitted to the plurality of guide pins 7, and the tube 8 contacts the inner peripheral surface of the back drum 1. The tube 8 is elastically deformed against the pressure received by the back drum 1 from a first pressing roller 15 described later, thereby preventing stress concentration and deformation in the back drum 1. Further, the inner peripheral surface of the back drum 1 and the guide pin 7 are prevented from rubbing directly. Not only does the metal rub against each other directly, it generates heat, but it also tends to produce black discolored residue, which is prevented.

The front flange 4 has a disc shape and has an outwardly facing boss portion 4a at the center, and an insertion hole 4b and a key groove 4c for inserting the drive shaft 5 are formed in the boss portion 4a. The front flange 4 can be detachably fixed to the drive shaft 5 while being prevented from rotating by a key 9 attached to the drive shaft 5. The front flange 4 is removed when the actual paste P is taken out from the inside of the back drum 1 or during cleaning. A plurality of pin holes 4d are provided in the vicinity of the outer peripheral edge of the front flange 4 at positions corresponding to the screw holes 3c of the rear flange 3 at equal intervals in the circumferential direction, and the rear flange 3 is provided in the pin holes 4d. The tip end portion of the guide pin 7 protruding from is inserted. The guide pin 7 is set to a length sufficient to protrude from the front flange 4, and its tip is formed into a tapered taper. The front flange 4 is partially opened except for the vicinity of the boss portion 4a and the pin hole 4d on the outer peripheral portion and the connecting portion 4e, and discharges the actual paste P accumulated inside through the opening 4f. Can be done.

Spacers 10 shown in FIG. 7 are interposed between the rear end of the cylindrical back drum 1 and the rear flange 3 and between the front end of the back drum 1 and the front flange 4 in order to avoid direct contact with each other. It is. The spacer 10 is made of a plastic having a small friction coefficient and excellent mechanical strength, and a pin hole 10a through which the guide pin 7 can be inserted is provided at a position corresponding to the screw hole 3c of the rear flange 3 and the pin hole 4d of the front flange 4. In other words, it is not a full circle but a quarter circle. The spacers 10 are inserted between the rear end of the back drum 1 and the rear flange 3 and between the front end of the back drum 1 and the front flange 4 so as to form a full ring as a set of four sheets. When an overload that makes the back ram 1 difficult to rotate due to the food material sandwiched between the back drum 1 and the first pressing roller described later being too large or too hard, The back drum 1 that is only sandwiched between the rear flange 3 and the front flange 4 slips between the front and rear spacers 10 and prevents damage due to overload resulting from forced rotation by the drive shaft 5.

A rear end side of the drive shaft 5 is rotatably supported by two bearings 11 on a part of a rear frame F2 constituting the machine, and a hollow shaft type motor 12 is attached between the bearings 11. The motor 12 has a built-in speed reducer and rotates at a predetermined rotational speed.
The front end side of the drive shaft 5 is supported by a bearing 14 of a front plate 13 that is detachably attached to the front frame F1, and prevents the drive shaft 5 from drooping. Since the boss 4a of the front flange 4 is in contact with the inner ring 14a of the bearing 14, the front flange 4 is prevented from shifting in the axial direction. The front flange 4 can also be fixed to the drive shaft 5 by screwing a bolt into the boss 4a.

The first pressing roller 15 circumscribing the back drum 1 is cylindrical and has shaft portions 15a projecting at both ends, and an elastic layer 15b made of elastic sponge or rubber is bonded or baked on the outer periphery. It is formed by the method. The length of the first pressing roller 15 is set slightly shorter than the entire length of the back drum 1 so that it can rotate between the spacers 10 arranged at the front and rear ends of the back drum 1.

The first pressing roller 15 is arranged so as to be parallel to the drive shaft 5 of the back drum 1, and the two support shafts 17 are attached to the bracket 16 fixed to the connecting beam F 3 that connects the front and rear frames F 1, F 2. The left and right side plates 18 and 18 suspended by 17 are supported by bearings 19 and 19. The side plates 18 and 18 are connected integrally by two upper and lower shafts 20 and 20 opposite to each other at a predetermined interval, and the first pressing roller 15 is disposed between the side plates 18 and 18. A connecting member 21 such as a rod end is attached to an intermediate portion of the lower shaft 20 that connects the side plates 18 on both sides, and a screw shaft 22 is fixed to the rear end of the connecting member 21. The two shafts 23, 23 arranged inside the frames F 1, F 2 are fixed to the frame F at both ends, and fixed to the two horizontal plates 24, 24 inserted through the two shafts 23, 23. A bearing 26 is attached to the girder 25, and a boss portion 27a of a rotary handle 27 for rotating the inner ring 26a of the bearing 26 is fitted and fixed to the inner ring 26a of the bearing 26. The inner ring 26a and the rotary handle 27 are integrally formed. It is designed to rotate. A screw hole 27b is provided in the shaft center of the rotary handle 27 and is screwed into the screw shaft 22. When the rotary handle 27 is rotated, the screw shaft 22 moves forward and backward. As the screw shaft 22 advances and retreats, the side plates 18 and 18 swing with the support shafts 17 and 17 as fulcrums.

A second pressing roller 28 is provided so as to circumscribe the backing drum 1 at a position advanced in the rotational direction by 45 ° on the outer periphery of the backing drum 1 from the first pressing roller 15. Similarly to the first pressing roller 15, the second pressing roller 28 has a cylindrical shape and is provided with shaft portions 28a at both ends. On the outer periphery of the second pressing roller 28, an elastic sponge or An elastic layer 28b made of rubber is formed by a technique such as adhesion or baking.

The second pressing roller 28 is arranged so as to be parallel to the back drum 1 and is attached to a bracket 29 fixed to a connecting beam F4 connecting the left portions of the frames F1 and F2 with two support shafts 30 and 30. A second pressing roller 28 is supported by a bearing 32 on the two supported side plates 31, 31. The side plates 31, 31 are connected by two shafts 33, 33 facing each other at a predetermined interval, and the second pressing roller 28 is disposed between the side plates 31, 31.
A connecting member 34 such as a rod end is attached to an intermediate portion of the shafts 33, 33 connecting the side plates 31, 31 on both sides, and a screw shaft 35 is fixed to the rear end of the connecting member 34.
A bearing 37 is attached to a girder 36 fixed to the two horizontal plates 24, 24 inserted through the two shafts 23, 23, and a boss of a rotary handle 38 that rotates an inner ring 37 a of the bearing 37. The portion 38a is fitted and fixed to the inner ring 37a of the bearing 37 so that the inner ring 37a and the rotary handle 38 rotate integrally. A screw hole 38b is provided in the shaft center of the rotary handle 38 and is screwed into the screw shaft 35. When the rotary handle 38 is rotated, the screw shaft 35 moves forward and backward. As the screw shaft 35 advances and retreats, the side plates 31 and 31 swing with the support shafts 30 and 30 as fulcrums.

A small motor 39 is attached to the rear side plate 31, and a sprocket 40 is fixed to a rotating shaft 39 a of the motor 39. A sprocket 41 is fixed to one shaft portion 28 a of the second pressing roller 28, and the sprocket 40 of the motor 39 and the sprocket 41 attached to the shaft portion 28 a of the pressing roller 28 are connected by a chain 42. The motor 39 rotates the second pressing roller 28.
The rotational speed is set so that the peripheral speed of rotation on the outer peripheral surface of the second pressing roller 28 is larger than the peripheral speed of rotation on the outer peripheral surface of the back drum 1.

A scraper 43 is disposed below the second pressing roller 28 in parallel with the axis of the back drum 1. This scraper 43 is used to scrape off the raw material residue, which is in a state of only a skin containing almost no real components after passing between the back drum 1 and the first and second pressing rollers 15, 28, from the outer peripheral surface of the drum 1. It is something to drop. As shown in FIGS. 8 and 9, the scraper 43 is elastically brought into contact with the backing drum 1 by the force of a spring. In this embodiment, the scraper 43 is made of a plastic or a relatively soft metal having excellent mechanical strength and high wear resistance. The scraper mounting portion 44a is provided above the lever 44 formed in a three-pronged shape. It is screwed so that the position can be adjusted vertically. The lever 44 is supported on the upper end portion 46a of another lever 46 by a support shaft 45 at a substantially intermediate position. The lever 46 is bent in a square shape, and this lever 46 is also supported by the bracket 48 with a support shaft 47 at a substantially intermediate position. The bracket 48 is fixed to a stay 49 provided to connect the lower portions of the frames F1 and F2. The lower end portion 44b of the lever 44 and the lower end portion 46b of the lever 46 are connected by a tension spring 50, and the lower end portion 44a of the lever 44 and the lower end portion 46a of the lever 46 are attracted to each other by the elasticity.

A known connection fitting 51 called a catch clip is attached to the central portion of the stay 49 provided at the lower part of the frames F1 and F2. The main body of the connecting metal 51 includes a latch 51a and an operation lever 51b, and engages and releases the receiving metal 51c attached to the lower side of the lever 46 by rotating the operation lever 51b.
In a state where the engagement between the latch 51a and the catch 51c is released (FIG. 9), the scraper 43 is separated from the outer peripheral surface of the back drum 1, but the latch 51a is engaged with the catch 51c and the operation lever 51b is pulled up. The lower portion 46b of the lever 46 is pulled, the lever 44 that is attracted to the lever 46 via the tension spring 50 rotates in the direction of the arrow X, and the scraper 43 comes into contact with the outer peripheral surface of the back drum 1 so that the It can be scraped off.

At the upper part of the front and rear frames F1, F2, a food material W insertion port 52 disposed above the back drum 1 is provided. A discharge hopper 53 is provided in front of the discharge port of the back drum 1 to prevent the granular powder paste P that has been back from flying out, and the actual paste P is in a box shape provided below the back drum 1. It falls into the actual container S.

The scraper 43 is detachably attached with chutes M and N having a concave cross section for dropping the peeled and remaining skin onto the residue receiving containers C and D. The residue dropped from the chute M is accommodated in the residue receiving container C, and the residue dropped from the chute N is accommodated in the residue receiving container D.

In the apparatus of the above embodiment, when the food raw material W is input from the input port 52, the food raw material W falls near the circumscribed portion of the back drum 1 and the first pressing roller 15. The dropped food material W is gradually sandwiched between the back drum 1 rotating in the direction of arrow Q (counterclockwise) and the first pressing roller 15. Since the first pressing roller 15 does not have a drive source, the first pressing roller 15 rotates as the back drum 1 rotates.
The food ingredient W crushed between the back drum 1 and the first pressing roller 15 has its actual component permeated through the numerous through holes 2 provided on the outer peripheral surface of the back drum 1 to correspond to its size. The actual paste P that has become grains of size is extruded into the inside of the back drum 1. The granular actual paste P that has passed through the through holes 2 adheres to the inner surface, or falls to the lower part and accumulates in layers. The actual paste P adhering to the inner surface of the back drum 1 falls to the lower part as the back drum 1 rotates.
When a certain amount accumulates on the inside of the back drum 1 inclined at a predetermined angle, it gradually moves toward the opening 4f with rotation and is discharged to the outside from the opening 4f. The actual paste P falls into a box-shaped actual container S disposed below the outlet of the back drum 1.

Since the food material W that has passed between the first pressing rollers 15 still contains a certain amount of actual components, the second pressing is performed between the second pressing roller 28 and the backing drum 1.
Unlike the first pressing roller 15, the second pressing roller 28 is linked to the motor 39 and rotates at a predetermined rotational speed. The peripheral speed of rotation of the outer peripheral surface of the second pressing roller 28 is set to be faster than the peripheral speed of rotation of the outer peripheral surface of the back drum 1, and is usually about 1.2 to 1.5 times. Peripheral speed is adopted. Depending on the type of food material W, a peripheral speed of 1.5 to 2 times may be employed.
The effects obtained by making the peripheral speed of the second pressing roller 28 larger than the peripheral speed of the drum 1 are as follows.
When the first squeezing is performed between the first pressing roller 15 and the staking drum 1, the skin containing a certain amount of actual components is firmly attached to the outer peripheral surface of the scouring drum 1. Even if the second pressing roller 28 is pressed against the back drum 1 in this state, it is difficult to further extract the actual ingredients because of the mechanism for pressing the food material against the back drum 1 and pushing it out through the through holes 2. However, by rotating the second pressing roller 28 faster than the back drum 1, the skin adhering to the outer peripheral surface of the back drum 1 is moved at a high speed so as to be shifted forward in the rotation direction, and the entrance of the through hole 2. In this example, the real component and the skin are subjected to shear separation. As a result, the actual component that could not be lined by the first pressing roller 15 can be further separated from the skin.
A unique effect that cannot be obtained simply by pressing the second pressing roller 28 against the backside drum 1 is obtained.

The skin that passes through the second pressing roller 28 and adheres to the outer peripheral surface of the drum 1 is scraped off by the scraper 43 and falls to the lower containers C and D via the chutes M and N attached to the lever 44. To do.

When a certain amount of the actual paste P is deposited in the actual container S, the actual container S is replaced with a new one, and the backing work is continuously performed.

When the backside work is completed, the operation is stopped. When the operation stop switch (not shown) of the operation box is pressed, both the motor 12 and the motor 39 are stopped.
After confirming a reliable stop of the machine, the bolt B fixing the front plate 13 is removed, and the front plate 13 is removed from the drive shaft 5 together with the bearing 14.
Subsequently, the front flange 4 is removed from the drive shaft 5, the back drum 1 is removed from the guide pins 7, and the actual paste P accumulated inside is scraped out to the actual container S or another container.

In FIG. 4, the entire apparatus is configured such that the back drum 1 is inclined downward, but it is also possible to configure the back drum 1 to be horizontal so that the actual paste is scraped out manually.

The actual paste backed by the apparatus of this embodiment is crushed and extruded as it is from the through-hole 2, and unlike the conventional product obtained by pumping and stirring, the generation of heat and the occurrence of stickiness are extremely low, Therefore, there is little damage to the flavor of the actual paste.
Since the backside drum 1 can be easily attached and detached, the necessary cleaning after work is facilitated and workability is improved.
By setting the peripheral speed of the second pressing roller 28 to be larger than the peripheral speed of the back drum, the yield of the actual component recovery is improved.
