The research aims to conduct experimental studies of the drying schedule for processing vegetable-origin organic materials using a microwave electro-technological installation. The design and development of a microwave electro-technological installation for processing vegetable-origin organic materials and agricultural crops are based on the solution of an agreed boundary value problem of electrodynamics and heat and mass transfer. The experiments on the microwave processing of vegetable-origin organic materials using a microwave electro-technological installation allowed us to identify the preferred process conditions, which involve the work of 7 magnetrons and a rotation mechanism of vegetable-origin organic materials along their axis. The processing time is less than 15 hours; the final humidity does not exceed 7%. The temperature change is uniform. The temperature at a depth of 1/4 of the thickness of the samples differs from the temperature on the surface of the samples by 0.5–1.0°C. The differences in the calculated and experimental data on the humidity of organic materials of plant origin do not exceed 3.8%, and on temperature, it is 4.3%. The creation of a microwave installation for the simultaneous microwave processing of vegetable organic materials and agricultural crops will significantly increase the energy and economic efficiency of the installation by reducing the processing time and increasing the quality of dried material quality. Moreover, unlike the existing ones, the proposed electro-technological installation contributes to the sale of more than two products with improved qualities, thus increasing the profits at the same energy costs.
