It sends back in mixing agitator and participates in next production process, reduce the dosage of organic adjuvants；
(4) dewatered sludge after fermented, dry is transported in product storehouse by auger conveyor and is stored up to organic native produce,
Organoclay product storehouse carries out 10%~15% organoclay returning charge to mixing agitator by conveyer belt, is further reduced organic adjuvants
Dosage.
