MAQOLA ANNOTATSIYASI

Convective drying refers to one of the energy-intensive processes used in chemical, woodworking, food and other industries. Therefore, in modern conditions, when there is a growing shortage and an increase in energy tariffs, it is important to develop and apply new effective methods of drying wet materials in industrial production, create high-performance drying equipment, improve the operation of existing dryers, which will contribute to the rational use of natural resources, reduce the cost of finished products and increase the competitiveness of production. Root crops are plants in which nutrients are concentrated in tubers or roots. Jerusalem artichoke refers to sugar-containing tubers, and beets, carrots, turnips, turnips, rutabagas, parsnips and couscous belong to root crops. These products are widely used for human and animal nutrition. Long-term storage of root crops in raw form requires large energy costs to maintain optimal temperature, humidity, gas composition in the storage and some other parameters. Even when maintaining optimal storage parameters, part of the crop spoils, and the other part loses its biologically active substances due to the natural processes of vital activity occurring in root crops. There are quite a few ways to store root crops. The high content of water and carbohydrates in root crops makes it difficult to preserve them. The cells of roots and tubers breathe during storage; enzymatic processes do not stop in them. With an increase in temperature and humidity of the air, the intensity of respiration increases, the loss of organic substances and vitamins increases.
