The invention relates to a method and apparatus integrated in a feed-production factory for processing and using the seeds of field pea-type leguminous plants. The seed of a pea-type plant is dehulled in a hulling device, crushed in a crusher, and finely ground in a pregrinder and in a jet mill. The flour is air separated in air classifiers into two or more fractions so that the starch granules originating from cotyledon cells are substantially included in coarse fractions and the protein granules substantially in fine fractions. For facilitating the fractionation, there is used a predetermined, selected variety of the pea-type leguminous plant. By effecting the grinding with a jet mill grinding technique it may be economically feasible to reach a sufficiently small particle size without subjecting the product to thermal injuries. The process is integrated as a part of the feed production of a feed factory in a manner that at least some of the flour fractions are administered into a mixed feed being prepared. The invention includes proteinaceous pea feeds including at least 35% pea protein. |
