Method and unit for the processing of sunflower-extraction meal

摘要

An optimal separation of sunflower seed meal into at least one fraction with high protein content and at least one fraction with high cellulose content is to be achieved with a method for the processing of sunflower-extraction meal, producing a fraction with a low protein content for use as fuel and a fraction having a higher protein content for use as animal feed, wherein the extraction meal is fed to a plurality of dissolving and extraction stages. This is achieved by - at least two protein removal steps, preferably by means of corrugated rolls or hammer blows or impact mills with impactation of the starting material in a short cycle sequence, - the subsequent sifting by means of sieves, as well as the collecting of the sifted material and the remaining coarse material.
