Roller Flour Mill Project Reports
Roller Flour mill serve the purpose of processing wheat to convert it into flour. The plant will have facility to produce, maida, suzi, atta and bran. These products will be sold as per the guidance issued for Food and Civil Supplies Department of the concerned state. Thus milling is an imperative physical function involved in converting wheat into its milled products. Separating the wheat grain into its constituents (bran, germ and endosperm) Wheat grains are the seed of the wheat plant, which is able to grow in kinds of soil and under widely differing climatic conditions.
Grain processing systems are generally based on the separation of the following components of the grain: Bran is the hard, brownish outer protective skin of the grain (varies from 6% in corn to 16% in wheat). Bran layers include the cuticle, mesocarp, cross layer, tube cells and testa. The bran layers are a concentrated source of dietary fibre.
Endosperm is the inner part of the grain (varies from 60% in rice, barley and oats to 80% of the grain in wheat). It provides the growing plant with food. The main nutrients in the endosperm are protein and carbohydrate. Aleurone consists of one or more layers of cells between the bran and the endosperm (8-10% of total grain). The number of layers varies from 1 cell thick in wheat, rye, oats and maize to up to 3 cells thick in barley and rice. The aleurone layer is a concentrated source of vitamins, minerals and other nutrients. Germ is the part of the seed that becomes a new plant if the seed is sown (varies from 12% in maize and 10% in sorghum to as low as 2% or 3% in other grains). It consists of the embryo and the scutellum. Most of the grain kernel's fat and vitamin E content is found in the germ. The RFM industry is basically in agro-based processing industry engaged in the manufacture of products based on wheat, namely maida, sooji, atta and bran. In some states, under special arrangements RFM units produce whole meal atta to meet the requirements of various distribution programmes.
