Abstract

A new design of solar drying plant with the active solar energy system is developed. It is proposed to use the K1-102 automated control system to diagnose the key parameters of air exchange in the solar dryer and to predict the intensity of heat exchange processes of oak veneer drying. This allows increasing the technological and power efficiency of the process of oak veneer drying in the solar dryer 2 times.

The regularities of the influence of the physical parameters of the environment and weather-dependent factors on the heat, mass, and moisture exchange processes of oak veneer drying in the solar dryer are determined. Estimation of energy, kinetic and dynamic parameters of the oak veneer drying process is given. The duration of the drying process in the solar dryer is experimentally determined. Performance characteristics of the drying object are investigated, depending on the set technological tasks (heating or drying) under standard insolation and meteorological conditions.

It is found that it is necessary to regulate air exchange, moisture release, rational moist coolant removal, solar energy flow in relation to the predicted changes in the minimum and maximum variation peaks of weather-dependent factors. This is important for intensifying the oak veneer drying processes and reducing the specific power consumption of the drying process due to solar energy.

The obtained results can be used in the development and improvement of technical means of oak veneer drying, to improve the technological and power efficiency of the process
