Description

Technical Field

[0001] The utility model relates to the technical field related to restaurant and kitchen waste treatment, and in particular to a crushing device for treating restaurant and kitchen waste. Background Art

[0002] Restaurant kitchen waste refers to food scraps, waste grease, expired food, etc. generated during food processing, catering services, and dining in hotels, restaurants, enterprise and institution cafeterias, and school canteens. Restaurant kitchen waste contains pathogens that can easily cause illness.

[0003] After extensive searching, I discovered Chinese patent publication number CN219724077U, which discloses a food waste crushing and stirring device, comprising a collection unit, a base, and a stirring reaction box. The driving end of the stirring motor is connected to a stirring rod within the stirring reaction box via a multi-stage transmission mechanism. The collection unit is connected to the stirring reaction box below via a lower hopper. A crushing unit is also provided between the collection unit and the lower hopper. The collection unit includes a collection hopper, which is provided with a first hopper body and a second hopper body. The first hopper body has a filter screen provided at the top inner side of the first hopper body, and a drainage hole is provided at the bottom outer side of the first hopper body. The structural arrangement of the collection unit, crushing unit, and stirring reaction box allows food waste to be crushed after entering the collection unit before entering the stirring reaction box below. This device has good integration and a small footprint.

[0004] To sum up, in the existing food waste treatment device, the adjustable performance of the crushing unit is poor, and the working spacing of the crushing unit cannot be flexibly adjusted; in addition, if the working spacing of the crushing unit is not suitable, the crushed garbage may need to be crushed again for subsequent processing.

[0005] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a crushing device for treating kitchen waste, so as to make it more valuable for industrial use. Utility Model Content
