ABSTRACT:
Disclosed is a dryer for drying articles, such as laboratory glassware. The dryer is in the form of a sealable cabinet having an internal heater, and ducting in the form of a closed circulatory loop connected to an external blower. By recirculating air through the dryer, rather than blowing air in one side of the cabinet and out the other, the air can be heated to a much higher temperature, thus drying the articles much more quickly and thoroughly, and reducing appreciably the time of a drying cycle. Additionally, because the dryer conserves heated air by recirculating it, the dryer consumes far less power than prior dryers of equivalent capacity, making it possible to use standard commercial power sources to operate this dryer, rather than the more expensive three phase power supplies now typically used.
