AI Technical Summary
Existing solar-powered grain dryers suffer from problems such as low drying efficiency, uneven heating of grain, small drying capacity per batch, long drying cycle, and high production cost.
The system combines a rotating mechanism and a heat collection mechanism. The main rotating rod drives the scraper to turn the grain, and the guide fan and circulation components promote the flow of hot air. The support frame and slide rail plate optimize solar energy reflection, improve the heat energy conversion efficiency, and transfer heat energy to the drying chamber through a heat exchanger.
It achieves uniform drying of grains, improves drying efficiency and single-batch processing capacity, reduces energy consumption, and meets the needs of large-scale production.
