Abstract
When drying seeds, pumpkin seeds are focused on the qualitative characteristics of the material, such as energy growth and germination. To solve this problem, experimental studies were carried out on a convective drying stand with the aim of choosing a rational drying regime. When justifying the seed drying regimes of pumpkin seed, the high energy costs for the process also play a role, which is more than 1.5 times as compared with the seeds of food purpose. Therefore, it is necessary to choose such drying regimes, in which energy consumption will be reduced and high germination of pumpkin seeds will be ensured, which is practically realized in this work through the use of step drying regimes. An increase in the intensity of drying of pumpkin seeds provides a stepped drying regime of 60/40 °C, a similarity of seeds at 98%, a reduction in the duration of the process 3 times compared with a temperature of 40 °C, which respectively reduces the energy costs of the process. Experimental and theoretical studies have shown that the drying of seeds in an elementary layer on a convective drying stand takes place during the incident drying rate and has 2 critical points. Theoretical studies are carried out using the Krasnikov method for finding a generalized drying curve and plotting a generalized drying rate graph that allows analyzing the drying process of pumpkin seeds. The intensity of growth of the given culture justifies the introduction staircase drying mode for 10 days germination sprout length was 61 mm, which is better than other thermal conditions at 3 percent or more.
