A device for forced ventilation and pneumatic discharge of the bulk material

Careful attention is paid to the production of grain. Of all the stages of the grain production, the most restricted is its post-harvest processing. If in general, in the post-harvest processing the cleaning and drying operations are solved positively, the operations of forced ventilation and subsequent temporary and long-term storage require further development. The existing plants for the post-harvest grain processing with forced ventilation are morally obsolete and physically worn out. All known stationary and portable ventilation devices in the form of channel, panel and telescopic structures have a significant disadvantage, such as the inability to transport grain material. This article presents a new design of a three-channel air-slide, enabling more efficient operations of forced ventilation and pneumatic grain discharge.
