The processes of dehydration and transformation of dry matter of apples are experimentally studied on the basis of differential thermal and thermogravimetric analysis. The kinetics of the process of apple thermolysis was investigated on the basis of differential thermal and thermogravimetric analysis. The thermoanalytical curves obtained by the method of non-isothermal kinetics were based on the experimental dependences of the change in the mass of the TGA sample, the rate of temperature change DTA, and the rate of change in the DTG mass. Differential thermal analysis was used to determine the thermal effect of the dehydration reaction. For apples in the temperature range of (376 ... 475) K, an endothermic effect is noted with an increase in temperature to (473 ... 495) K, a significant destruction of substances is noted. On the basis of the performed theoretical and experimental studies, it is proposed to use variable thermal effects during convective and microwave drying, as well as variable hydrodynamic regimes of a layer of dispersed material in the production of rapidly recovered dried apples.

Rapeseed oil production technology implies repeated heating of oilseed raw materials; therefore, there is a high probability of biochemical and physico-chemical changes in its composition and a decrease in the nutritional value of the finished product. It is known that rapeseed seeds are balanced in protein, amino acids and vitamins, among which a special role belongs to antioxidants - tocopherols, the level and isomer composition of which determine the oil's resistance to oxidation. Therefore, it is particularly interesting to study the effect of temperature exposure on the quantitative content of the listed components and the qualitative composition of rapeseed seeds. At the final stages of rapeseed oil production, the seeds should arrive dried to a certain moisture content and with the maximum possible preservation of native properties. Therefore, the key link of the machine-hardware scheme of rapeseed oil production developed by us is a microwave drying apparatus with a combined power supply. The aim of the work is a comparative study of the quality indicators of rapeseed dried in a microwave device with a combined power supply and a traditional method. As a result of experimental studies, a comparative analysis of biochemical and physico-chemical changes in rapeseed seeds was carried out, which allows us to draw a positive conclusion about the feasibility of using a microwave drying apparatus as part of the rapeseed oil production line.
