A method and apparatus for drying pieces in bulk, such as metal screws being electrolytically galvanized. The pieces are charged in a rotating perforated barrel through which drying air is passed. The barrel is positioned in a drying chamber which also contains a ventilator for circulating the air, an air heater and a dehumidifier. These components are arranged so that dry air is drawn through the barrel and the charge by vacuum from the portion of the barrel not filled by the charge. Flexible seals between the barrel outer casing and a suction box direct the flow of air substantially completely through the charge. |
