Abstract:
In a material dryer apparatus including a housing with a drying basket disposed therein and having a drying stream heater and blower associated therewith, a control arrangement for said dryer apparatus comprising: temperature sensing means disposed to sense the drying stream temperatures entering upstream and exiting downstream said drying means; relative humidity sensing means disposed to sense the drying stream relative humidity entering upstream and existing downstream said drying basket; and control means connected to said temperature sensing means and said relative humidity sensing mean, said control means being connected to said heater and said blower to cooperatively and intermittently modulate drying heat input and drying stream volume delivery in said heater and said blower with respect to each other and in accordance with sensed temperatures and relative humidity levels entering upstream and exiting downstream said dryer basket.
