[0053] In the embodiment, the bottom plate 6 is also provided with a frozen re-scraping structure 39. The frozen re-scraping structure 39 is arranged on the right side of the water tank 7 and below the conveying belt 2. When the conveying belt 2 is used to transport food with high viscosity and difficult to clean, the conveying belt 2 cannot be thoroughly cleaned by only the brush roller 10. The frozen re-scraping structure 39 can be used to freeze and dry the food with high viscosity and difficult to clean, and then scrape the food. The frozen re-scraping structure 39 comprises a fixed groove 40. The top of the fixed groove 40 is open. The top of the fixed groove 40 is in clearance fit with the bottom of the conveying belt 2. A plurality of electric telescopic rods 41 are fixedly arranged on the inner bottom wall of the fixed groove 40. The output ends of the electric telescopic rods 41 are all fixedly connected with the same bracket 42. A liquid nitrogen storage tank 43 is fixedly arranged in the bracket 42. A plurality of nozzles 44 are connected with the liquid nitrogen storage tank 43 through pipelines. Control valves are arranged in the pipelines. The nozzles 44 are fixedly arranged on the top of the bracket 42. A through hole is formed in the bracket 42. A second scraper 45 is arranged on the right side of the bracket 42. The height of the second scraper 45 is higher than that of the nozzles 44. A strip-shaped hole is formed in the bracket 42 between the nozzles 44 and the second scraper 45. When food with high viscosity and difficult to clean is encountered, the height of the bracket 42 is adjusted by the electric telescopic rods 41. The second scraper 45 is in abutment with the conveying belt 2. Then, the liquid nitrogen is sprayed from the nozzles 44 to instantaneously freeze the food with high viscosity and difficult to clean. Then, the food is thoroughly cleaned by the second scraper 45. The residues are collected in the fixed groove 40 through the strip-shaped hole. The cleaning effect of the food processing cleaning conveying device is further improved. After use, the bracket 42 is reset by the electric telescopic rods 41. The fixed groove 40 can protect the liquid nitrogen storage tank 43. A box door 46 is hingedly arranged on the right side of the fixed groove 40. The residues in the fixed groove 40 are cleaned through the box door 46.

[0054] In use, the food processing self-cleaning conveying device of the embodiment is started. The motor 3 drives the conveying roller 5 to rotate, thereby driving the conveying belt 2 to convey the raw materials. At the same time, the second synchronous wheel 11, the first synchronous wheel 8 and the synchronous belt are matched to drive the brush roller 10 to rotate. The brush roller 10 is cleaned. At the same time, the brush roller 10 is immersed in water. The brush roller 10 is wetted and cleaned by water. The cleaning ability of the brush roller 10 is maintained. The pressing roller 15 is in abutment with the brush roller 10. The excess cleaning water on the brush roller 10 is squeezed out. The water content of the brush roller 10 is prevented from being too high. The conveying belt 2 is prevented from being too wet. Then, the threaded rod 16 is rotated. The threaded rod 16 drives the pressing roller 15 to move through the first sliding block 14. The abutment force of the pressing roller 15 and the brush roller 10 is changed. The water content of the brush roller 10 is adjusted. The flexibility of use is improved.

[0055] When the second synchronous wheel 11 rotates, it also drives the driving rod 12 to rotate. During the rotation of the driving rod 12, the rotating frame 20 is pressed down. The rotating frame 20 rotates downward through the extension rod 22 and the intermediate rod 23. The intermediate rod 23 drives the brush plate 24 to move downward. Then, after the driving rod 12 is out of contact with the rotating frame 20, the brush plate 24 is reset under the action of the torsion spring 21, and then contacts the brush roller 10, stirring the cleaning water at the same time. This reciprocating process cleans the brush roller 10, thereby improving the cleaning degree and cleaning effect of the brush roller 10.

[0056] While the second synchronous wheel 11 is rotating, the push rod 17 is driven to move back and forth through the eccentrically installed drive shaft 29. The push rod 17 drives the second slider 25 to move back and forth through the side rod 28. The second slider 25 drives the slag collecting bucket 26 and the first scraper 27 to move, so that the first scraper 27 can scrape off the material that is firmly adhered to the conveyor belt 2. The fallen material falls into the pull-out box 38 after being guided by the slag collecting bucket 26, which is convenient for centralized processing.

[0057] When the liquid level in the water tank 7 drops, the float 35 falls accordingly, causing one end of the swing frame 34 to rotate downward, while the driving groove 36 at the other end drives the plug 30 to move upward through the connecting shaft 32, allowing tap water to enter the water tank 7 through the outlet pipe 37. Conversely, when the water level rises, the plug 30 closes the water supply pipe 18, thereby improving the degree of automation of the device.

[0058] When encountering food residues that are difficult to remove due to their high viscosity, the height of the bracket 42 is adjusted by the electric telescopic rod 41 so that the second scraper 45 abuts against the conveyor belt 2. Then, liquid nitrogen is sprayed through the multiple nozzles 44 to instantly freeze the difficult-to-remove substances, and then the second scraper 45 completely removes them, further improving the cleaning effect of the food processing cleaning conveyor device. The residue inside the fixed tank 40 is regularly cleaned through the box door 46.

[0059] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
