Design and Research of Home Automatic Kitchen Waste Composting device

Abstract

As a part of kitchen waste, vegetable peelings has some special features such as high water rate,highorganic matter content and good biodegradability. By biological composting, such waste can be recycled, reduced, and become harmless. Based on analyzing the experimental results for the composting and fermentation of peel and vegetable leaves, an automatic composting apparatus applying for household was designed and researched. The function such as crushing pre-treatment, material transfer, fermentation and separation were realized by using the function components such as wringer blade and cross blade broken baffle,ect. The odor problem during fermentation was solved by activated carbon adsorption. Finally, solid fertilizer and fermentation broth with decontamination function were obtained.
