Annotation

Studies on finding rational regimes for drying rapeseed based on drying kinetics and qualitative characteristics are presented. The value of the acid number of oil and laboratory germination of rapeseed on the 7th day of germination were taken as a qualitative characteristic.
Experimental studies of the kinetics of the rapeseed drying process were performed on a convective drying stand using an automatic program for collecting and processing information, which makes it possible to obtain more accurate experimental data. According to the obtained experimental data with the help of an automatic program for collecting and processing information, graphs of the process kinetics from the influence of the coolant temperature are constructed. The presented graphs show the drying curves and drying speed curves that characterize the drying process that takes place during the period of falling drying speed.
The study of the kinetics of the drying process of rapeseed in a single-stage mode at coolant temperatures of 50 - 80°C showed that for better quality it is necessary to use low-temperature modes. The acid number of oil in this temperature range does not change significantly and is 1.03 - 1.8 mg / g of oil. These values of the acid number of the oil correspond to the normative value.
The greatest effect on the germination of rapeseed is observed from the temperature of the coolant. Increasing the temperature by 10 ° C in the temperature range from 50 to 80 ° C reduces the germination of the material. According to laboratory studies, we determined the drying regime of 50 ° С with a germination of 97% to be the most expedient and rational. All other drying regimes significantly reduce the germination of rapeseed and can not be recommended, as the germination value is less than the state standard of Ukraine 2240-93.

Keywords: drying, regime, rapeseed, kinetics, acid number of oil, germination, temperature.
