Manure dewatering machine can be widely applied to the separation of high concentration organic waste such as chicken, cattle, horse, all kinds of intensive livestock and poultry manure, distiller’s grains, starch residue, sauce residue, and slaughterhouse. After solid-liquid separation and dehydration, the material has a low moisture content, a fluffy appearance, no viscosity, no odor reduction, and no hand squeezing. The treated animal manure can be directly packed or sold. The water content of livestock manure after treatment is the best condition for organic manure fermentation and can be fermented directly to produce organic fertilizer.
