Determination of soya grain strength, reduction and loss in storage and processing

Abstract

This scientific article analyzes, that with an increase in soybean production, an important role is given to reducing the loss of soybean grain per harvester and from crushing, when the plants are harvested, and post-harvest processing of grain in the production of reproductive seeds. The studied climatic conditions of the Amur region during the soybean harvesting period (October) are characterized by low precipitation and low relative air humidity, it helps dry the plants. Identified, that under these conditions, soybeans and grain are losing strength and, under the influence of the working bodies of motovil and reaper, beans are pulled off or uncovered and grain losses are noted, a threshing and separation devices (MSU) of a grain harvester crush grain when milled, resulting in crop losses. Formulated in the process of scientific research, that the tensile strength or destructive load of soybean kernels by grade at humidity 6,5% change from 13.03 before 29.02 kg. Knowing the destructive load for soybean grain, proposal for Action, prevent destructive modes of operation for the working organs of the threshing and transporting devices of the combine. Based on the reliably obtained regression equation, the response surface is represented, determining the force of the action of the working bodies of the combine in the function of the changing speed from 8.0 before 20 m/s, mass of grain from 0.15 before 0.35 g., which in the September variety increases to 10 N.
