摘要 |
The present invention provides a device and a method for dense phase transport of a granular product, such as seed. A dense phase delivery line includes a porous medium located along a side wall of the dense phase delivery line. When air and seed are send through the delivery line, a control cover may be moveably positionable over the porous medium to control the flow of air through the porous medium and to start, stop, or otherwise control the dense phase transport of seed through the dense phase delivery line.
