Description

Technical Field

[0001] This invention belongs to the field of food processing waste technology, specifically relating to a method and apparatus for treating waste from the production of stuffed foods. Background Technology

[0002] During the production of filled foods (such as steamed buns and dumplings), a large amount of waste containing a mixture of filling and dough is generated due to reasons such as improper shaping, deviations in filling ratio, and damaged dough. This waste typically includes intact filled semi-finished products, broken and exposed filling products, and cut scraps.

[0003] In existing food production waste treatment, fillings (such as minced meat) in filled waste are tightly adhered to the dough, making it difficult to achieve effective separation using traditional manual sorting or simple crushing methods. This results in the fillings and dough being mixed and wasted, leading to raw material waste. Current technologies often use a single crusher to pulverize the waste as a whole. After the fillings and dough are mixed and pulverized, they form a paste that is difficult to reuse. This not only makes it impossible to recover valuable fillings and dough but also increases the difficulty of subsequent processing. Summary of the Invention

[0004] The purpose of this invention is to provide a method and apparatus for treating waste from the production of stuffed foods, aiming to solve the problems of difficulty in separating fillings from dough and low separation efficiency in the prior art for waste from stuffed foods.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a waste treatment device for stuffed food production, comprising: a housing, a feed inlet on the side wall of the housing, a feed conveyor for conveying waste at the feed inlet, a screen-removing roller and a material-breaking roller rotating inside the housing, a skin-breaking structure for piercing the outer skin of the waste on the outer circumference of the screen-removing roller, and a material-breaking structure for peeling off the outer skin of the waste on the outer circumference of the material-breaking roller; The screen-breaking roller and the material-breaking roller are connected by a transmission mechanism and can rotate in opposite directions to form a speed difference, so that the waste that has been peeled by the screen-breaking structure can throw out the internal filling under the action of centrifugal force; The machine casing is equipped with a scraper for scraping off waste material attached to the screen removal roller. The machine casing is also equipped with a vibrating plate located below the scraper. The vibrating plate has screen holes and is used to vibrate and screen the waste material, allowing the residual waste material to fall to the bottom of the machine casing through the screen holes. A belt conveyor is located downstream of the vibrating plate to transport the waste material after vibration screening. A calendering roller is installed on the belt conveyor.

A first drive motor is installed on the outer wall of the housing, and the output end of the first drive motor is connected to the screen-unwinding roller.

[0009] As a method and apparatus for treating waste from the production of stuffed foods according to the present invention, preferably, the transmission ratio of the driving gear to the driven gear is 1.2:1 to 2.0:1.

[0010] As a waste treatment device for stuffed food production of the present invention, preferably, the machine housing is provided with a vibration mechanism, and the vibration plate is inclinedly arranged inside the machine housing with its higher end hinged to the inner wall of the machine housing.

[0011] As a waste treatment device for stuffed food production of the present invention, preferably, the vibration mechanism includes a striking mechanism and a resetting mechanism. The striking mechanism is used to periodically strike the vibrating plate, while the resetting mechanism drives the vibrating plate to reset, so that the vibrating plate can vibrate up and down.

[0012] As a waste treatment device for stuffed food production of the present invention, preferably, the striking mechanism includes a drive shaft and a rotating shaft. The drive shaft is rotatably disposed inside the housing, and an output plate is disposed on the outer circumferential surface of the drive shaft. The rotating shaft is rotatably disposed inside the housing, and a rotating plate is disposed on the rotating shaft. A striking plate and a transmission plate are disposed on the rotating plate. A second drive motor is installed on the side wall of the housing. The output end of the second drive motor is connected to the drive shaft. The drive shaft drives the output plate to rotate, and the output plate drives the striking plate to swing through the transmission plate, so that the striking plate strikes the vibrating plate. A torsion spring is provided on the outer circumference of the rotating shaft. One end of the torsion spring is connected to the inner wall of the housing, and the other end is connected to the rotating plate.

[0013] As a waste treatment device for stuffed food production of the present invention, preferably, the reset mechanism includes a fixed block, a connecting column slidably disposed on the fixed block, and a reset spring sleeved on the outside of the connecting column. One end of the connecting column is connected to the vibrating plate, one end of the reset spring is connected to the vibrating plate, and the other end is connected to the fixed block.

[0014] A method for treating waste from the production of stuffed food products includes the following steps: S1. Conveying and feeding: Waste generated during the production of stuffed foods is transported into the processing unit. S2, Damaged Mounting: The outer skin of the waste is pierced by the skin-breaking structure on the screen-removing roller, and the waste is then attached to the outer circumference of the screen-removing roller. S3, Differential Stripping: The waste is peeled off by a crushing roller that rotates in the opposite direction to the screen-removing roller and has a speed difference, so that the outer skin of the waste is broken and an opening is formed. S4. Separating the filling: The unwinding roller continues to drive the waste to rotate, and the filling inside the waste is thrown out from the opening through centrifugal force. S5, Vibration screening: After the filling is separated, the waste is scraped off the screen roller and falls onto the vibrating plate. The vibration of the vibrating plate further separates the remaining filling from the dough, and the remaining filling falls through the sieve holes. S6. Dough rolling: The selected dough sheets are transported to the rolling mill for rolling processing, so that they can be recycled later.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The method and apparatus for treating waste from the production of stuffed food products involves using the skin-breaking structure of the screen-breaking roller to pierce the outer skin of the waste and attach the waste, and then using the material-breaking structure of the material-breaking roller to perform differential peeling, so that the outer skin forms a full opening. Then, centrifugal force is used to throw out the filling inside, which achieves complete separation of the filling from the dough and improves the separation efficiency.

[0016] 2. The method and apparatus for treating waste from the production of stuffed food products adopts a progressive separation process of "puncture-peeling-throwing out". The filling is thrown out and collected in a relatively intact state, while the dough is kept in sheet or strip shape, which is convenient for separate recycling and significantly improves the reuse value of the recycled materials.

[0017] 3. The method and apparatus for treating waste from the production of stuffed food products involves scraping the waste onto a vibrating plate, which vibrates periodically in conjunction with a striking mechanism and a resetting mechanism. Residual filling is sieved through the sieve holes, while the dough is transported downstream, further improving the purity of the separation between the filling and the dough.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-7The present invention provides the following technical solution: a method and apparatus for treating waste from the production of stuffed food products. The housing 1 is a closed box structure made of stainless steel, which has good corrosion resistance and hygiene performance. The side wall of the housing 1 is provided with a feed inlet 11, and a feeding conveyor 2 for conveying waste is provided at the feed inlet 11. The feeding conveyor 2 can be a belt conveyor or a screw conveyor to continuously and evenly transport the waste generated on the production line of stuffed food products into the interior of the housing 1.

[0022] Inside the housing 1, a screen-removing roller 3 and a material-breaking roller 4 are arranged in parallel and rotating manner. The outer circumferential surface of the screen-removing roller 3 is evenly distributed with a skin-breaking structure 31. Specifically, the skin-breaking structure 31 consists of multiple sharp skin-breaking needles 32 arranged in a ring array along the outer circumferential surface of the screen-removing roller 3. When waste is transported to the vicinity of the screen-removing roller 3, the skin-breaking needles 32 can pierce and penetrate the outer skin of the waste, thereby "hanging" the waste on the screen-removing roller 3 and rotating with the screen-removing roller 3.

[0023] The outer circumferential surface of the crushing roller 4 is provided with a material breaking structure 41. The material breaking structure 41 consists of multiple triangular material breaking blocks 42 arranged in a ring array along the outer circumferential surface of the crushing roller 4. In terms of installation position, the triangular material breaking blocks 42 and the skin breaking needles 32 on the screen breaking roller 3 are staggered in both the axial and circumferential directions to avoid mechanical interference between the two, and at the same time, they can better cut open the outer skin of the waste.

[0024] In the working direction, the pointed corner of the triangular material breaking block 42 is adapted to the rotation direction of the crushing roller 4 and the relative movement direction of the waste, so that the pointed corner can effectively insert into and cut open the outer skin of the waste fixed by the skin breaking needle 32. Then, the opening of the waste is enlarged by the two triangular plates, which also prevents the outer skin from sticking to the triangular material breaking block 42.

[0025] The screen-unwinding roller 3 and the crushing roller 4 are connected by a transmission mechanism 5. The transmission mechanism 5 is installed on the outer wall of the housing 1. The transmission mechanism 5 includes a drive gear 51, a driven gear 52 and a transmission gear 53. The drive gear 51 is fixedly connected to the power output shaft of the screen-unwinding roller 3, the driven gear 52 is fixedly connected to the power output shaft of the crushing roller 4, and the transmission gear 53 is rotatably disposed between the drive gear 51 and the driven gear 52 and meshes with both of them.

[0026] Please see Figure 1-5 The outer wall of the housing 1 is also equipped with a first drive motor (not shown in the figure). The output shaft of the motor directly drives the screen-removing roller 3 to rotate. When the screen-removing roller 3 rotates clockwise, the driven gear 52 will drive the crushing roller 4 to rotate in the opposite direction through the transmission gear 53.

[0027] Meanwhile, the transmission ratio between the driving gear 51 and the driven gear 52 is 1.2:1 to 2.0:1 (preferably 1.5:1 in this embodiment), which can achieve a preset speed difference between the screen-unwinding roller 3 and the breaking roller 4 (the speed of the screen-unwinding roller 3 is higher than that of the breaking roller 4), and the driven gear 52 and the transmission gear 53 have the same number of teeth.

[0028] During operation, the waste material fixed by the breaking needle 32 rotates with the unscrewing roller 3 and passes through the breaking roller 4, which rotates in the opposite direction and at a slower speed. The high-speed rotating triangular breaking block 42 will cut open the outer skin of the waste material, creating a large opening. Subsequently, the unscrewing roller 3 continues to drive the waste material with its outer skin broken to rotate at high speed. Under the action of strong centrifugal force, the filling inside will be thrown out through the opening and separated from the outside of the dough. The thrown-out filling falls to the bottom of the machine casing 1 for collection. A discharge port is provided at the bottom of the machine casing 1 to facilitate the recycling of the filling. This is existing technology and will not be described in detail here.

[0029] Below the side of the screen-unwinding roller 3, near the inner wall of the housing 1, a scraper 6 is fixedly installed. The scraper 6 includes a connecting shaft 61 disposed inside the housing 1 and scraper shafts 62 disposed at intervals on the connecting shaft 61.

[0030] When the empty dough sheet, after filling, rotates with the unwinding roller 3 to the scraper 6, it is forcibly scraped off the breaking needle 32 by the scraper shaft 62 and falls onto the vibrating plate 7 below. The vibrating plate 7 is inclinedly arranged inside the machine housing 1, with its higher end hinged to the inner wall of the machine housing 1 and its lower end extending downstream. The vibrating plate 7 is covered with fine sieve holes, and a vibration mechanism 8 is provided inside the machine housing 1 to drive the vibration of the vibrating plate 7.

[0031] Please see Figure 6 and Figure 7 The striking mechanism 81 includes a drive shaft 811 driven by a second drive motor and a rotating shaft 812 rotatably disposed inside the housing 1. An output plate 813 is fixed on the drive shaft 811, and a rotating plate 814 is fixed on the rotating shaft 812. A striking plate 815 and a transmission plate 816 are mounted on the rotating plate 814.

[0032] A torsion spring 817 is also fitted on the rotating shaft 812. One end of the torsion spring 817 is connected to the inner wall of the housing 1, and the other end is connected to the rotating plate 814. When the drive shaft 811 rotates, the output plate 813 will periodically press down on the transmission plate 816, causing the rotating plate 814 to drive the striking plate 815 to swing upward and violently strike the bottom of the vibrating plate 7.

[0033] At the same time, the torsion spring 817 is twisted and stores energy. When the output plate 813 is separated from the transmission plate 816, the rotating plate 814 and the striking plate 815 quickly reset under the restoring force of the torsion spring 817, waiting for the next strike.

[0034] The reset mechanism 82 includes a fixing block 821 fixed to the inner wall of the housing 1, a connecting column 822 that slides through the fixing block 821, and a reset spring 823 sleeved on the connecting column 822. The upper end of the connecting column 822 is connected to the bottom of the vibrating plate 7, and the upper end of the reset spring 823 abuts against the vibrating plate 7 and the lower end abuts against the fixing block 821.

[0035] Please see Figure 3-7 The reset mechanism 82 provides a continuous downward pulling force to the vibrating plate 7, enabling it to quickly return to its original position after being struck, and cooperates with the striking mechanism 81 to form a high-frequency, stable up-and-down vibration.

[0036] The empty dough sheets scraped off from the unwinding roller 3 fall onto the vibrating plate 7. Under the action of vibration, a small amount of filling that was not removed by centrifugal force and was attached to the dough sheets will fall through the sieve holes to the bottom of the machine casing 1, while the more intact dough sheets will move downstream along the inclined vibrating plate 7 under the action of vibration and their own weight.

[0037] A belt conveyor (not shown in the figure) is connected to the downstream end of the vibrating plate 7. A calendering roller 9 is installed on the belt conveyor. The sheet material after vibration screening is conveyed to the calendering roller 9 by the belt conveyor, where it is rolled or calendered to make it into sheet or strip material of uniform thickness, which is convenient for subsequent collection and utilization. The calendering roller 9 is driven by a motor, which is existing technology and will not be described in detail here.

[0038] Based on the above-described apparatus, this embodiment also provides a method for treating waste from the production of stuffed foods, comprising the following steps: S1. Feeding: The feeding conveyor 2 continuously transports unqualified buns, dumplings and other waste generated during production into the machine casing 1.

[0039] S2, Piercing and Hanging: When the waste comes into contact with the high-speed rotating screen-removing roller 3, its outer skin is pierced by the piercing needle 32, and the waste is thus fixed on the screen-removing roller 3 and rotates with it.

[0040] S3, Differential stripping: The screen-removing roller 3, which has the waste material fixed in place, brings the material into the working area between the screen-removing roller 3 and the crushing roller 4. As the crushing roller 4 rotates in the opposite direction, the triangular screen-removing blocks 42 on its surface will cut open the outer skin of the waste material, forming a large opening.

[0041] S4. Filling Separation: The waste material after the outer skin is broken continues to rotate at high speed with the unwinding roller 3. Under the action of centrifugal force, the fluid filling inside is thrown out in large quantities through the opening on the outer skin, thus separating it from the outer skin.

[0042] S5. Vibration screening: Empty dough sheets with completed filling separation are scraped off the screen-removing roller 3 by the scraper 6 and fall onto the vibrating plate 7 below. The vibration of the vibrating plate 7 causes any residual filling that may be adhering to the dough sheets to be further removed and fall to the bottom through the sieve holes. The clean dough sheets then move downstream along the vibrating plate 7.

[0043] S6. Sheet calendering: The screened sheet is conveyed by a belt conveyor to the calendering roller 9. The sheet is rolled and calendered by the calendering roller 9 to make its thickness uniform and form sheet material that is easy to recycle.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
