TAILIEUCHUNG - Study on application of fuzzy control system for the grain drying equipment of agro products

Results obtained from the study of dynamic model over drying process using fuzzy control system for grain moisture reduction have brought prospects to drying technology to increase dried products quality and its economic effectiveness in the area of storage and processing of agro-products. | Đỗ Thị Tám và Đtg Tạp chí KHOA HỌC & CÔNG NGHỆ 139(09): 183 - 187 STUDY ON APPLICATION OF FUZZY CONTROL SYSTEM FOR THE GRAIN DRYING EQUIPMENT OF AGRO-PRODUCTS Do Thi Tam1*, Tran Hong Thao2, Pham Van Lang2 1 College of Technology - TNU, Vietnam Institute of Agricultural Engineering and Post-Harvest Technology, 2 SUMMARY Control system is used in drying equipment in the process of drying grain aiming at reducing the moisture of agro-products down to a desired level. Conventional methods applied in drying control process have shown limited results as seen in uneven dried products quality, high rate of energy consumption. Modern control method, in which fuzzy control system is applied, proves its advantages by eliminating the above limitations. However, in order to obtain drying control results as desired, thorough studies on drying process for an accurate prediction of control model are required. Results obtained from the study of dynamic model over drying process using fuzzy control system for grain moisture reduction have brought prospects to drying technology to increase dried products quality and its economic effectiveness in the area of storage and processing of agro-products.

If the temperature of drying agent exceeds the allowable drying one, grain cracking and embryo deterioration situation may easily occur. The proper drying agent temperature also depends on initial moisture of grain to be dried. The temperature
