Description

Technical Field

[0001] The invention relates to the technical field of in-situ cleaning, and in particular to a refrigerator cleaning machine. Background Art

[0002] Cleaning in place is CIP (CLEAN IN PLACE) cleaning. CIP technology does not require the equipment to be disassembled when cleaning, so it is very suitable for cleaning some equipment that is difficult to disassemble or move, such as some pipeline equipment or tank equipment. CIP technology has been widely used in food, beverage and pharmaceutical factories.

[0003] A freezer is a mechanical device that uses a compressor to change the pressure of a refrigerant gas to achieve low-temperature refrigeration. It is used in the chemical, papermaking, pharmaceutical and food processing industries. At present, food freezers have various structures. Some large food freezers are not easy to move and disassemble, but they need to be cleaned, decontaminated and disinfected after running for a period of time. Therefore, it is necessary to use in-situ cleaning technology to improve the existing cleaning machines.

[0004] The Chinese invention "An on-site cleaning device for quick-freezing equipment" with publication number CN109226019A provides an on-site cleaning device for quick-freezing equipment, including a valve array assembly and a rod rotating nozzle device. The valve array assembly includes a pump station, a pipeline, a clamp-type pneumatic angle seat valve, an insulated storage body, and a main valve. The clamp-type pneumatic angle seat valve is connected to the pipeline and then installed and fixed on the insulated storage body. The main valve connects the pump station to the pipeline, and the pipeline is connected to the rod rotating nozzle device. After the pump station is assembled, it is connected to the pipeline and stands on the ground. This invention adopts on-site cleaning, which can be cleaned in all directions. At the same time, the rod rotating nozzle device is used to clean the insulation storage board, platform, evaporator, fan and mesh belt inside the quick-freezing equipment. The speed of rotation of the rod rotating nozzle device is adjusted by adjusting the air pressure mixed with the cleaning liquid, and the water consumption is relatively small.

[0005] This invention discloses an on-site cleaning device for quick-freezing equipment, which can perform all-round cleaning. However, for some large food freezers using spiral mesh belts, the structure of this invention cannot clean the mesh belts in all directions without dead angles.

[0006] The Chinese utility model "An online cleaning device for a circulating conveyor mesh belt" with publication number CN203955584U provides an online cleaning device for a circulating conveyor mesh belt, including a bridge frame and a conveyor mesh belt placed on the bridge frame, a spray device is provided above the lower layer of the conveyor mesh belt near the discharge end, and a brush cleaning device is provided below. In the cleaning process of the utility model, the cold water sprayed from the spray pipe cooperates with the brush cleaning device below at the same time, spraying and cleaning at the same time, which not only realizes the online cleaning of the conveyor mesh belt, but also leaves no residue on the conveyor mesh belt after cleaning, and the cleaning is relatively thorough and has a good cleaning effect. At the same time, the device will not affect the normal production of the equipment, has a simple structure, is easy to operate, and has reliable performance. It effectively eliminates the problem of wear and tear of the equipment by residues, greatly improves the utilization rate of the equipment, and the entire cleaning process does not require manual operation, which greatly reduces the labor intensity of workers and improves production efficiency. It has a high degree of automation, strong applicability, and is easy to promote and use.

The water outlet pipe 4 extends from the upper end surface of the cabinet 1 and is connected to the distribution pipe. The water inlet pipe 5 extends from the upper end surface of the cabinet 1, and the water inlet pipe 5 includes a hot water inlet pipe 51 and a cold water inlet pipe 52. A disinfectant tank 6 and a disinfectant pump 7 are also arranged inside the cabinet 1. The disinfectant pump 7 is connected to the disinfectant tank 6 through a pipe, and the disinfectant tank 6 is connected to the water outlet pipe 4 inside the cabinet 1 through a pipe. The disinfectant tank 6 is provided with two, and the disinfectant pump 7 is provided with two, and one disinfectant tank 6 corresponds to one disinfectant pump 7. Different disinfectants are arranged in different disinfectant tanks 6. The disinfectant pump 7 pumps the disinfectant 7 into the water outlet pipe 4 and sprays it out from the nozzle to disinfect and sterilize the mesh belt with different disinfectants to ensure thorough disinfection.

[0046] The freezer comprises a spiral mesh belt and a bracket beside the spiral mesh belt. The spiral mesh belt forms a hollow cylindrical structure. When the freezer is working, the mesh belt moves spirally upward from the bottom.

[0047] The water outlet pipe 4 outside the cabinet 1 is connected to the upper cleaning branch 8, the inner wall cleaning branch 9, the outer wall cleaning branch 10 and the bottom cleaning branch 11 through the distribution pipe. The water outlet pipe 4 outside the cabinet 1 first extends vertically upward, then extends horizontally, and four branches are separated from the horizontally extended pipe. The four branches then extend vertically upward until the height exceeds the height of the spiral mesh belt 12 of the refrigerator. At this time, the four branches extend horizontally again to form the entire distribution pipe. Four angle seat valves 13 are arranged at the connection between the four branches and the pipes extending laterally from the water outlet pipe 4. The four angle seat valves 13 control the switches of the four branches. Each angle seat valve 13 is electrically connected to a solenoid valve 14 arranged inside the cabinet 1.

The bottom cleaning branch 11 deeply cleans the upper and lower sides of the initial part of the mesh belt when the refrigerator is running.

[0053] An air filter regulating valve 15 is fixedly connected to the upper side of the cabinet 1, and the air filter regulating valve 15 is fixedly connected to the solenoid valve 14. The air filter regulating valve 15 is fixedly connected to a valve body air inlet 16 extending from the upper end surface of the cabinet 1. The air filter regulating valve 15 is used to supply air to the solenoid valve 14.
