Development and optimization of rotation drying silo

The grain storage loss is serious in farm after harvest due to lack of storage and drying technologies. A new drying silo was developed based on the idea of letting the grain "move", changing from passive drying to active drying. It is used not only for drying but also for short term storage. Also, it can be compiled with mechanical ventilation and heating. The field studies showed that our rotating silo can be used for reducing the grain moisture to safe level in an economic way and keep the quantity and quality of grain safe. This provides a strong support for the reduction loss in the post-harvest section with energy-saving.
