Experimental modeling of the microwave grain drying process in preparation for grinding

УДК 664.71.05

Grain drying is a complex, continuous and energy-intensive process. One of the ways to improve the quality of grain (and therefore its products) and to save energy is the use of the automatic control system of the technological process (ACS TP). The technological process of grain drying includes measuring and regulation of such indicators as moisture and temperature. These aims are achieved with the help of devices, which make it possible not only to regulate the drying process, but also to archive the technological process data for their further analysis. There has been made an experimental facility for researching the process of microwave grain drying with multifunctional system of the technological process control and information archive application using MPR-51- SHCH4 meter-controller and AC4 interface adapter, which are being OVEN firm devices. The block diagram of the improved control system of drying grain is given. Its characteristics, working principle and the experimental research methodology are described. Experimental studies on shelling and drying installation have been conducted. The test results are given in the article.
