摘要

Continuous process for the dry extraction of the fat of raw materials, in the form of animal by-products, of poultry and fish to produce fat and pressed organic fertilizer, characterized in that it comprises the operations of reducing the raw materials to an average particle size, feeding the raw material particles into a holding container and thoroughly mixing said particles while they are heated to a temperature of the order of 87.7ºC to 98.8º c, including the step of keeping the raw material particles in the holding container, during a period of permanence at least practically equal to the flow regime of one hour of the raw materials that are elaborated, to make homogeneous the raw materials and to eliminate a part of the humidity of the same ones; continuously extract the homogeneous raw material from the holding tank and further reduce its average particle size, feed the raw material thus reduced to a cooking vessel and heat said raw material to a temperature of the order of 107ºC to 135º c, to further reduce its content of moisture and release fats from it, and continuously extract the raw material from the cooking vessel and then separate the fats released from the waste.
