[0002] Food waste, also known as kitchen waste, is a common type of household waste. Food waste generally includes discarded vegetable leaves, leftovers, leftovers, fruit peels, eggshells, tea dregs, bones, etc. Existing food waste is generally first processed by a food waste treatment device. During the initial treatment, the food waste is generally only chopped up, then put into the corresponding garbage can, and then transported to the treatment plant for subsequent treatment. However, due to the high water content of food waste, the chopped food waste still contains a high amount of water, resulting in a large weight of the food waste after the initial treatment, which is not convenient for transportation and subsequent treatment. Summary of the invention
