Abstract

The article presents technical approaches to increasing the energy efficiency of initial moisture content of plant material corresponding to the beginning of the drying period of a two-stage convective vacuum-impulse dryer using a preliminary analysis of the temperature regime in the drying plant and the possibility of using heat accumulators based on materials capable of accumulating thermal energy as a result of a phase transition. The analysis of temperature regimes was carried out using a non-contact method for measuring the temperature field, implemented in a thermal imager. A convective drying unit acts as a source of pre-charging of heat accumulators. using technical approaches Paraffin with a melting point of 50-70 ºС was used as a material capable of accumulating thermal energy in a phase transition to increasing the energy efficiency of initial moisture content of plant material
