[0026] Further, the circulating water pipe 5 is provided with a filter 32, and the filter is used to filter the impurities in the water inside the cleaning tank.

[0027] Working principle: open the sealing door at the inlet and outlet of the cleaning box. Carefully put the crawfish to be cleaned into the cleaning basket. Since the both ends of the placing plate are provided with sliding grooves, and the both sides of the cleaning basket are provided with sliding grooves matched with the sliding grooves, only need to align the cleaning basket with the placing plate, and gently push along the sliding grooves, the cleaning basket can be stably fixed on the placing plate, so that the cleaning basket will not shake or shift during the cleaning process. After completing the loading, press the door closing button on the control panel again to close the sealing door. At this time, the sensor at the inlet and outlet position starts to work to detect whether the sealing door is completely closed. If it is detected that the door is closed, the sensor will transmit a signal to the controller to inform that the equipment can enter the next cleaning operation. When the equipment detects that the sealing door is closed in place, the controller starts to start the micro-nano bubble water pump. Water is transported to the main pipeline under the action of the micro-nano bubble water pump, and then flows quickly along the main pipeline, and finally enters the cleaning tank through the cleaning pipeline. The micro-nano bubbles will suddenly burst when they gather to a certain extent near the stains and impurities on the surface of the crawfish, and instant local high temperature and high pressure are generated, which can destroy the structure of the stains and impurities and separate them from the surface of the crawfish. Moreover, a large amount of active oxygen such as hydroxyl radicals will be released after the bubbles burst. These active oxygen has strong oxidation effect and can decompose organic pollutants such as oil and protein on the surface of the crawfish and organic compounds that may cause fishy smell, so as to realize deep cleaning and deodorization. The crawfish cleaned is moved to the upper end of the cleaning tank through the lifting assembly, and the spray assembly is started to clean the crawfish. The water on the spray disc can completely wash away the foam and stains on the crawfish. The sealing door is opened, the cleaning basket is taken out, and the cleaning is completed. The equipment is ready for the next cleaning.

[0028] In summary, the cleaning is efficient and thorough, the micro-nano bubbles can deeply wrap the dirt in the difficult-to-clean parts of the crawfish, can ensure the freshness of the crawfish, and can kill bacteria and remove impurities. The lifting assembly drives the crawfish to move and the spray assembly washes away the impurities, so as to realize omnidirectional cleaning. The manpower and time are saved, the automatic operation does not need manual cleaning, a large amount of crawfish can be quickly cleaned, and the cost is reduced.
