Abstract

The use of the technology of active ventilation of the sugar beet piles allows reducing the loss of beet pulp by up to 5%, increasing the duration of operation of the sugar factory by 9-22% and reducing the cost of sugar by 2-4.5%. The installation of ventilation branches is carried out directly during the formation of the sugar beet piles and is limited by the time for installation work, since it is necessary to install from 6 to 12 branches in one shift. The unification of the size of the passage section of the ventilation branch makes it possible to increase the productivity of installation work and prevent work stoppages of the sugar beet pilers during the formation of sugar beet piles. According to the results of analytical and theoretical studies, dependencies have been identified for determining the design parameters of ventilation branches, taking into account the technical characteristics of shoulder-laying machines and heavy-duty vehicles with a trailer, as well as the physical and mechanical properties of sugar beet root crops. Taking into account the height and length of the field clamp, the distance between the ventilation branches, the number of ventilation branches and the length of one ventilation branch are determined. With a length of 120 meters and an optimal height of 6 meters, the number of ventilation branches is 16 pcs, the distance between them is 6 meters, the length of the ventilation branch is 26 meters. With the maximum permissible air velocity of the main air ducts at 11 m/s and the ventilation intensity of 40 m3 /hour per 1 ton of sugar beet root crops, the air consumption for one ventilation branch is determined to be equal to 22400 m3 /hour. Taking into account the speed and air flow, the following are determined: the area of the duct is 0.5026 m2 , the area of one air outlet is 0.005 m2 , the number of air outlets is 150 pcs. The obtained parameters will serve as the basis for the development of a system for the automatic formation of ventilated sugar beet piles.
