Improving the ventilation system of the warehouse by means of renovating the air duct

The safety of the potato depends on the ventilation equipment. It is possible to store potato for up to 8 months with the help of microclimate created with the help of ventilation inside the bulk of agricultural products. However, the distribution of venting air from the ducts to the bulk is uneven. Due to this, some foci of self-warming inside the bulk appear which leads to potatoes damage at the storage stage. The analysis of the methods used to study air filtration parameters in bulk layers confirmed that changes in pores of the layer are quite a challenge. Theoretical studies have established the dependence of the day-light area ratio on parameters of the improved air duct. Analysis of the obtained dependence showed that the gap is 20 mm for battens sized 40x40 mm and the the day-light area ratio is more than 0.167. Later, in the course of experimental studies, it was found that the pressure losses from the fan depend on the losses in the duct itself, on the basis of which the head loss formula in the ventilation system of the potato warehouse was obtained. The results of the research were checked and accepted for implementation and implemented at "Podsosenka" LLC, Ryazan Oblast, Shatsky District in 2017.
