Description

Technical Field

[0001] The invention relates to the technical field of restaurant and kitchen waste pretreatment equipment, in particular to an integrated restaurant and kitchen waste pretreatment machine. Background Art

[0002] Food waste pretreatment equipment is a kind of equipment that can convert food waste into something that is easier to handle or reusable. It usually consists of processes such as crushing, compression, separation and fermentation. Food waste, also known as swill, is domestic waste generated in daily life. It is easy to emit bad odor and spread bacteria. Food waste pretreatment equipment can effectively decompose and treat food waste, reduce the volume of food waste or convert it into reusable resources.

[0003] According to the Chinese patent application No.: 202321667389.6, an integrated kitchen waste treatment device is disclosed, including four brackets, two of the first telescopic cylinders are fixedly connected to the top with a damping block, the two damping blocks are fixedly connected to the top with a second shell, and the second shell is rotatably connected to the inside with an extrusion rod. The traditional integrated kitchen waste treatment device is not functional during operation. When the traditional device processes the garbage, the first step is to crush the garbage by driving the crushing device driven by the motor, and the vibration is large when processing the garbage, making the whole device unstable. The buffer component provided in the device, wherein the first telescopic cylinder can minimize the shaking generated by the extrusion rod when it is working, and the damping block above it and the external damping shell can greatly reduce the noise generated by the extrusion rod when it is working, so as to increase the stability and noise reduction function of the device;
