Research and Development of Automatic Small and Medium-sized Restaurant-kitchen Waste Disposal Machine

Taking small and medium-sized kitchen waste treatment equipment as the research object, based on the analysis of the advantages and disadvantages of the crushing type and the microbial decomposition type, the existing treatment equipment is improved, and the treatment process is reorganized. This study designed and developed waste treatment equipment. It includes automatic feeding device, solid waste crushing device, solid-liquid separation device, oil-water separation chamber, weighing device, fermentation device, water purification circulation system, cleaning device, electrical control system and so on. A water purification and circulation system is designed. The treated water can be controlled by PLC through the circulation system into the crushing chamber for desalt or into the solid-liquid separation chamber and fermentation chamber for cleaning, so as to realize the reuse of treatment water. The control system redesigned based on PLC technology can realize the whole process of intelligent control of food waste disposal. The control panel can realize the opening, closing, cleaning and other functions of the kitchen waste processor, and the whole process of food waste treatment can be monitored through the LCD screen, and the operation is simple.
