For example, patent document CN 211246829U discloses a kitchen waste treatment mechanism, which comprises a feeding device, a crushing device, a separating device and a storing device, which are connected in sequence, wherein kitchen waste is fed into the feeding device, then enters the crushing device, is crushed, then is discharged into the separating device, and is directly discharged or is fed into the storing device. The in-line kitchen waste crusher is commonly used in hotels, restaurants and family kitchens in countries such as Europe, america, japan, and the like, and over 94% of cities in the United states use the kitchen waste crusher. After the domestic introduction, some city environmental protection departments send out text and try to popularize the kitchen garbage crusher to be used in commercial kitchens and resident families, but the defects are found quickly: kitchen garbage directly discharges the sewer pipe through the output after smashing, can arouse the sewer pipe after long-term the use and block up, has very big pressure for residential area drainage pipe network and municipal drainage pipe network, and then some residential area property do not have the catering industry kitchen, resident family to use kitchen waste rubbing crusher in the clear order. The popularization and the use of the direct-discharge type kitchen waste crusher are greatly limited by the conditions of a municipal drainage pipe network and the sewage treatment capacity.

Therefore, kitchen waste products treated by the kitchen waste crusher are not directly discharged into a sewer pipeline, and a separating device is required to separate residues from sewage, so that the purposes of reducing the volume and the weight of the kitchen waste are achieved, and the sewer pipeline and a sewage pipeline network are not influenced.

For ships, according to the regulation requirements of 7.1 and 7.1.2 in GB/T3552-2018 ship water pollutant discharge control Standard issued in 2018, kitchen waste generated in a ship kitchen is collected and discharged into a receiving facility in inland rivers and offshore sailing.

2. The dehydration mode of negative pressure and drying is adopted, a large amount of heat energy is consumed for drying, the treatment cost of the kitchen waste is high and uneconomical, and in addition, the noise generated when a vacuum water suction machine used for negative pressure dehydration operates and the odor generated when the vacuum water suction machine is dried and dehydrated pollute the environment of a workshop and cause discomfort for operators.

3. The dehydration mode of spin-drying by the centrifuge is adopted, the centrifuge can generate great noise when running at high speed, and after the kitchen waste treatment work is finished, the garbage residues are adhered to the bristles of the spiral brush roller for conveying in the centrifuge, so that the garbage residues cannot be washed away, and bacteria are easy to breed particularly; the bristles on the edge of the spiral brush roller are worn after the accumulated use time is long, so that the conveying function is reduced or disappeared, residues attached to the wall of the spin-drying barrel are difficult to convey to the discharge hole, the residues are retained on the wall of the spin-drying barrel of the centrifugal machine, the discharge is not accumulated, and the treatment function is lost.

4. The kitchen waste is food waste, bacteria are easy to grow in a humid environment, smell generated during storage is very bad, and the kitchen waste treatment devices cannot inhibit the growth of the bacteria.

5. After the kitchen waste treatment device is used, residues can be left in the kitchen waste treatment device, the kitchen waste treatment devices do not have a self-cleaning function, bacteria are bred in the device in the standby process to generate peculiar smell, and the next use feeling is influenced.
