Wet poultry manure are sent into hopper of rotary poultry manure dryer by screw conveyor, then the wet poultry manure enter the drum installed with slope to horizontal line from the higher side, and hot air enters the drum from the lower side.

Then poultry manure and hot air mix together when the drum of poultry manure dryer is rotating. Poultry manure goes to the lower side by gravity when the drum is rotating. Lift plates on the inner side of drum lift poultry manure up and down in order to make poultry manure and hot air mix completely, which is designed to improve the drying and heat efficiency of rotary poultry manure dryer.
