Abstract
An apparatus for drying and conveying a material includes a vibratory fluid bed dryer having a perforated drying deck on which material is deposited, said fluid bed dryer including a vibratory drive system capable of imparting a variable angle vibratory force to the deck. A flash dryer is also provided, having a fan and heater for supplying hot air through the fluid bed dryer deck and a cyclone for collecting finished, dried material particles.
Claims20
A system for drying and conveying a moisture-laden material comprising:
- a fluid bed dryer comprising:
- a housing having a material inlet at a first end thereof, an overs outlet at a second end thereof, and a finished material outlet;
- a conveying deck on which said material is conveyed having a porous conveying surface through which said hot air is directed;
- and
- an inlet air header having a plurality of inlet air ports in fluid communication with said housing, said inlet air head supplying drying fluid to a bottom surface of said conveying deck;
- and
- a flash dryer in fluid communication with said finished product outlet having an exhaust for pulling dried material from said finished product outlet, and a cyclone storage hopper into which dried material is deposited.
