The role of physical properties of lupine seeds in the hulling process

Nowadays the lupine varieties contain less alkaloid what makes it possible to use them as feed components in larger proportions. The purpose of this paper is to provide some new possibilities of improving lupine seed quality, by application of simple mechanical hulling method. The influence of hulling conditions on the quality of final product was analyzed. Some factors that affect the hulling process kinds of used equipment as well as the physical properties and chemical composition of lupine seeds were discussed. The best results of hulling process was acquired on the specially adapted roller mill. Preliminary treatment of raw material also affected the hulling process in the large scale.
