Description

Technical Field

[0001] The invention relates to the technical field of kitchen waste treatment, and in particular to a kitchen waste machine. Background Art

[0002] Kitchen waste refers to the waste generated in the daily life of residents and food processing, catering services, unit catering and other activities, including discarded vegetable leaves, leftovers, leftovers, fruit peels, eggshells, tea residues, bones, etc. Its main sources are family kitchens, restaurants, hotels, canteens, markets and other industries related to food processing. Since kitchen waste contains a lot of water, it is easy to breed bacteria and stink if left for a long time, polluting the environment. Kitchen waste machines are often used to treat kitchen waste. Existing kitchen waste machines crush kitchen waste and discharge kitchen waste after crushing. The existing ones on the market are heating and stirring with a heating plate to slowly evaporate the moisture of kitchen waste, thereby achieving the effect of drying kitchen waste; a heating plate is installed at the bottom of the trash can, and the stirring blade in the trash can is driven by a motor to rotate and stir at a low speed, so that the garbage moisture produces steam, and the water vapor is discharged through the exhaust system. This method of heating, stirring and steaming the garbage moisture is relatively long, with large heat loss, and it cannot dry and crush hard kitchen waste. Moreover, after the kitchen waste is heated, the residual water in the trash can for a long time will cause the garbage to have a peculiar smell, which is harmful to the environment and human health. Traditional food waste disposers use traditional heating plates to remove moisture and dry food waste, but they have disadvantages such as long time, low efficiency, easy scaling on the heating plate, and uneven heating.
