Design of A New Type Horizontal Rotary Drying Chamber

In order to overcome the adverse effect of traditional grain drier on grain quality, a new type horizontal rotary drying chamber was designed and developed. The characteristic of this equipment is that the grain is dried at low temperature, and the whole machine rotates slowly to stir the grain, so as to ensure the uniformity of moisture content after the grain is dried, reduce the mechanical damage to grain in the drying process, and ensure the grain drying quality. In order to verify the performance of the equipment, a corn drying test was carried out. After 48 hours of continuous drying, the moisture content (24% wet basic) of 30.8t newly harvested high-moisture corn was dried to 15%, the drying curve was smooth, the drying process was stable, the non-uniformity after drying was less than 1%, and the unit energy consumption was about 0.19 kW-h/ (1% moisture -t). The experimental results showed that the moisture content of corn after drying was uniform, and the energy consumption was low. Therefore, it is a new warehouse type suitable for large farmers’ corn drying and short-term storage, and provides a new technology method and idea for grain drying and storage in the future.
