ABSTRACT:
An apparatus is employed for drying liquid, preferably ink, on a medium, which entails heating air and blowing it across the surface of the medium at high velocity. The heated air is recaptured and recirculated resulting in lower energy usage for heating and a reduced relative humidity of drying air to enhance drying. Various structural configurations are disclosed but each has a common feature of creating an air dam at the point of entry of a medium along a media path and at the exit point. The use of a baffle adjacent to the medium path acts as a deflector for the heated air to distribute it across the medium surface at high velocity and also creates ports for expressing and recirculating heated air.
