Abstract

Abstract D R A W I N G 10. A CIRCULATING AIR DRYER INCLUDING A CHAMBER HAVING A SPACE FOR HOLDING MATERIALS TO BE DIRED, A REVERSIBLE POWER-OPERATED AIR MOVER FOR SELECTIVELY CIRCULATING AIR THROUGH SAID SPACE IN EITHER OF OPPOSITE DIRECTIONS WITH SUCH AIR MOVING FROM THE EXHAUST SIDE OF THE MOVER INTO AND THROUGH SAID SPACE AND THENCE TO A NEGATIVE PRESSURE AREA ON THE SUCTION SIDE OF THE MOVER, ONE EXHAUST PORT CONNECTING WITH THE ATMOSPHERE AND COMMUNICATING WITH SAID CHAMBER AT ONE REGION WHICH IS ON THE SUCTION SIDE OF THE MOVER AND AT NEGATIVE PRESSURE WITH THE MOVER CIRCULATING AIR IN ONE DIRECTION THROUGH SAID SPACE, AND ANOTHER EXHAUST PORT ALSO CONNECTING WITH THE ATMOSPHERE AND COMMUNICATING WITH SAID CHAMBER AT ANOTHER REGION WHICH IS ON THE SUCTION SIDE OF SAID AIR MOVER AND AT NEGATIVE PRESSURE WITH THE MOVER CIRCULATING AIR IN THE OPPOSITE DIRECTION THROUGH SAID SPACE, SELECTIVELY OPERABLE POWER-OPERATED FAN MEANS FOR PRODUCING AN EXHAUST FLOW OF AIR FROM SAID ONE REGION OF THE CHAMBER TO SAID ATMOSPHERE THROUGH SAID ONE EXHAUST PORT WHEN SAID ONE REGION IS AT NEGATIVE PRESSURE AND MOVEMENT OF AIR IS IN SAID ONE DIRECTION AND FOR PRODUCING AN EXHAUST FLOW OF AID FROM SAID OTHER REGION OF THE CHAMBER TO SAID ATMOSPHERE THROUGH SAID OTHER EXHAUST PORT WHEN SAID OTHER REGION IS AT NEGATIVE PRESSURE AND MOVEMENT OF AIR IS IN SAID OTHER DIRECTION, AND MEANS FOR INTRODUCING MAKEUP AIR AND MEANS FOR INTRODUCING HEAT TO THE CIRCULATING AIR AFTER SUCH CIRCULATING AIR PASSES THE REGION WHERE EXHAUST FLOW IS TAKING PLACE AND BEFORE SUCH AIR ENTERS INTO SAID SPACE WITH AIR BEING CIRCULATED IN EITHER OF OPPOSITE DIRECTIONS THROUGH SAID SPACE.
