The articles to be processed are uniformly placed into a packing box on the article conveyor belt 700 through the sorters 601 in the sorting and packaging device, and then are transported through the packaging conveyor belt, so that the protein-based preservation process is completed.

The automatic biological fresh-keeping system of this application embodiment include a series of assembly line automation equipment, be connected with the conveyer belt between each position, pending article are poured into from the introduction sample area, are evenly tiled article conveyer belt 700 after arranging again, in soaking ultrapure water cleaning equipment behind the conveyer belt, cleaning equipment has the agitator, can accelerate the flow of water, has spraying system, can more thorough washing pending article. Then, the object is conveyed on an object conveyor belt 700, and the ultraviolet sterilizing lamp 301 is arranged on the conveyor belt, so that the object to be treated can be further sterilized and disinfected. After the disinfection is finished, the object to be treated further enters protein solution wrapping equipment, a layer of protein film is wrapped in the protein solution pool, and the object enters an automatic dryer to be dried and formed into a film. The protein coating equipment comprises a stirrer for promoting the circulation of the protein solution, and the coating can also be carried out by a protein spraying system. The dryer comprises a temperature and humidity control unit 501 and a wind speed control unit, so that better film formation of protein is facilitated. And finally, subpackaging and packaging the to-be-processed articles through a conveying belt. The process of cleaning, sterilizing, coating protein solution, automatically drying, boxing and packaging of fruits, medicinal materials and objects to be processed is automatically finished by utilizing assembly line equipment. The main advantages are that the method is suitable for large-scale automatic fresh-keeping of the articles to be treated; the user simplifies the operation, and saves time and labor; is suitable for special application scenes, and precious Chinese medicinal materials, such as fresh ginseng, dendrobium, cordyceps sinensis and the like; the design of the preservation unit can increase the production scale by duplicating the preservation unit.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
