The blower dryer unit is a partially recirculating dryer. It recirculates a nominal 90% of the air flow to conserve energy, and draws in 10% room air to keep the recirculating air stream from becoming saturated with moisture. It has a 16 gauge stainless steel chamber, 5 feet long with a large access door for inspection and cleaning. It is designed to circulate 1400 CFM of air at a nominal 150ºF. This value is chosen for operator comfort and to protect plastic ware from heat damage.
