DEVELOPMENT OF OPTIONS OF TECHNOLOGICAL SCHEMES PROCESSING OF MAIN TYPES OF GRAIN RAW MATERIALS

Abstract

The processes of processing of grain raw materials are quite common at food and processing enterprises in Ukraine. This is due to the significant volumes and wide variety of these raw materials, as well as a wide range of semi-finished products and finished products that are obtained from them. In particular, the country's enterprises process such types of grain crops as wheat, barley, rye, corn, oats, rice, sorghum, millet, chumiza, mogar, paiza, buckwheat (buckwheat family), mealy amaranth (amaranth family). Peas, beans, lentils, soybeans and other legumes are also grown in large volumes. All these raw materials come from different farms, in different conditions, in a wide range of varieties and quality, thus, even for the same type of grain raw materials such parameters as the shape and size of grains, their weight, moisture, glassiness, hardness, degree of damage and many others may differ significantly. Depending on the type of products obtained from grain raw materials (flour, cereals, malt, bran, starch, gluten, molasses, alcohol grains, vegetable oil, oilcakes, meal), the technologies for its preliminary processing may have significant differences. The purpose of this work is to develop a methodology for choosing a rational sequence for processing grain raw materials, taking into account the initial quality parameters, conditions of a specific production and criteria for the efficiency of working processes (productivity, energy intensity and quality of finished products). The article also provides options for technological schemes for the preliminary processing of the main types of dry grain raw materials. The proposed sequence for the development of these technological schemes can further serve as the basis for creating a computer program for automated synthesis and analysis of rational options for technological processes for processing dry grain raw materials.
