摘要

Procedure and system of continuous dry extraction of the fat of raw materials in the form of by-products of animals, poultry and fish, to produce fat and inedible residues, where the raw or raw materials are heated and cooked to release the fats of the same in a single cooking operation, characterized in that the process comprises the steps of: reduce the raw materials to an average particle size; feeding the raw material particles directly at the inlet end of an elongate cooking vessel having a discharge end opposite said inlet end; heating and cooking the raw materials while they are kept in said vessel to the extent of reducing the moisture content thereof to about 7 to 20%, which comprises the steps of establishing and maintaining a temperature gradient between the inlet ends and leaving the container, the materials being heated at the inlet end of the container at a temperature of the order of about 93.3ºC to 115ºC and at the outlet end at a temperature of the order of 115ºC to 137º c; keep the materials in the container with a residence time to the monkeys equivalent to a flow regime of one hour of the materials under development, and continuously stir the materials while they remain in the container; continuously removing cooked material from the discharge end of the container; and separating the fats released from the cooked matter discharged in the absence of additional cooking of said material.
