[0002] Spiral quick freezer is a kind of high-efficiency and fast freezing equipment, which is widely used in food processing, biological products and chemical raw materials industries. Spiral quick freezer occupies a small area, has a high degree of automation, is highly airtight, has less contact with the outside world, has small cold air loss and saves costs. The spiral quick freezer has a longer freezing chain, which increases the freezing contact time, thereby improving the freezing quality and output per unit time.

[0003] Since the spiral quick freezer is well sealed, the odor inside the freezer is not easy to dissipate, and it is easy for the odor to cross-pollinate when freezing different foods. In addition, the spiral quick freezer uses a cold air blower to circulate the internal air, and the air circulation is slow, which affects the quick freezing efficiency.

[0004] In view of this, research and improvement are carried out on the existing problems, and a single spiral quick-freezing machine is provided, aiming to solve the problems and improve the practical value through this technology. Utility Model Content

[0025] The steam generator 10 is arranged on one side of the discharge end of the spiral conveyor belt 3; the steam pipe 11 is connected to the steam generator 10, and the steam pipe 11 is arranged between the upper and lower layers at the discharge end of the spiral conveyor belt 3, and the spray heads 12 are evenly arranged on the outer wall of the lower part of the steam pipe 11; steam is sprayed from the spray heads 12 to wash and sterilize the spiral conveyor belt 3 to keep the spiral conveyor belt 3 clean; the water tank 13 is arranged below the spray heads 12 for receiving the water generated by steam condensation.

[0026] Specific implementation steps:

[0027] During use, the quick-frozen food enters from the feeding end of the spiral conveyor belt 3. The air cooler 5 is turned on, and the air blows onto the spiral conveyor belt 3 after passing through the evaporator 4 to quick-freeze the food. After the air passes through the spiral conveyor belt 3, it impacts the inner wall of the box body 1. Under the suction force generated by the circulation fan 7, the air moves to both sides. When the air passes through the activated carbon plate 9, the peculiar smell in the air is absorbed. When it is necessary to sterilize the spiral conveyor belt 3, the steam generator 10 is turned on, and the steam sprays out from the nozzle 12 through the steam pipe 11 to sterilize the spiral conveyor belt 3. The condensed water generated by the steam falls into the water tank 13.

The support frames are symmetrically arranged on both sides of the spiral conveyor belt, and one side of the support frame is fixedly connected to the inner wall of the box body. The circulation fan is arranged on the side of the support frame close to the evaporator. The activated carbon plate is fixedly arranged with the support frame through the fixing strip. The circulation fan speeds up the speed of the air in the box body flowing back to the evaporator, improving the quick-freezing efficiency. And when the air flows through the activated carbon plate, the peculiar smell in the air is absorbed, preventing the quick-frozen food from having a mixed taste. Through the steam pipe being arranged between the upper and lower layers at the discharging end of the spiral conveyor belt, and the nozzles being evenly distributed on the outer wall of the lower part of the steam pipe, the steam sprays out from the nozzles to wash and sterilize the spiral conveyor belt, keeping the spiral conveyor belt clean. Through the improvement of the single-body spiral quick-freezing machine, the utility model has the advantages of improving the air circulation speed in the spiral quick-freezing machine, high quick-freezing efficiency, and washing and sterilizing the spiral conveyor belt, thus effectively solving the problems and deficiencies in the prior art and equipment.
