Key Operating Points for Drying Materials in a Biology organic Fertilizer Dryer
The core challenge of biology organic fertilizer dryers , which differ from ordinary fertilizer dryers, is to reduce moisture content to meet standards without killing beneficial bacteria at high temperatures. Operation and control must take into account three key factors: temperature, rotation speed, and feed rate. Before feeding, assess the basic condition of the raw materials. After granulation, the moisture content is typically around 30%, with loose granules and no large clumps. Crush and screen any lumps beforehand to prevent accumulation and blockage in the drum. Feeding should be continuous and uniform, avoiding sudden changes in quantity. Excessive feeding will cause material accumulation in the drum, incomplete drying, and excessive moisture content in the output. Insufficient feeding will cause the material to be exposed to high temperatures too quickly, resulting in significant inactivation of the microorganisms. Drying temperature must be strictly controlled i...
