Research status and prospect of mixed flow dryer

Crop harvesting efficiency has improved dramatically with the expansion of the crop planting scale and the popularization of mechanized harvesting methods. Grain mechanized drying is a significant development direction of postpartum crop processing. The traditional artificial drying efficiency is low and unsuitable for modern agricultural production. The mixed flow dryer has attracted extensive attention as the most widely used dryer. This paper expounds on the working principle and structural composition of the mixed flow dryer and compares the research status at home and abroad from three aspects: key component design, control system research, and auxiliary research means. This paper introduces the energy configuration of the mixed flow dryer and the main problems of the dryer, such as poor equipment universality, low degree of automation, inaccurate simulation test results, large dust in the drying process, and non integrated machine technology. The mixed flow dryer is prospected by improving equipment universality, developing automatic monitoring and monitoring components, improving modeling accuracy, designing and developing relevant dust removal equipment, and mechanical technology integration.
