[0002] The present application relates to the technical field of waste treatment, for example, to a waste treatment device. Background Art

[0003] Kitchen waste refers to waste generated from daily life, food processing, catering services, and workplace meal services. It includes discarded vegetable leaves, leftovers, rice, fruit peels, eggshells, tea leaves, bones, and more. Its primary sources are home kitchens, restaurants, canteens, markets, and other food processing-related industries. To clean up this waste, a kitchen appliance typically uses a waste disposer installed under the sink. This appliance, powered by an AC or DC motor, uses centrifugal force to pulverize the food waste within the pulverizing chamber, which is then recycled.
