Equipment integrated pretreatment machine, conveying unit, bio-fermentation unit,waste gas and oil-water separation treatment unit into a whole. Make bio-degradation becomes extremely efficient. The kitchen waste is fermented into primary organic waste in as shorter time with the decrement up to more than 90%. Through multiple optimization of industrial design concepts and strict manufacturing management, higher equipment quality and lower power consumption can be achieved. More scientific noise reduction measures achieves better consumer experience.
