PURPOSE:To dry with low irregularity irrespective of change of stacking state of boxes on a ventilation trestle by providing a ventilation rate-regulating means for regulating a passage amount of drying gas at a position corresponding between an inlet and a side in the trestle. CONSTITUTION:Boxes which contain objects to be dried such as agricultural products, etc., are stacked on a ventilation trestle, and dried. A boxlike casing 11 opened at its upper surface of the trestle 1 is partitioned by a partition wall 12 to form six ventilation chambers 13, inlets corresponding to the chambers 13.ire formed at a side of the casing 11, and air flow chambers 3 are connected to the inlets through dampers 2. Ventilation rate-regulating means is provided at a position corresponding between the inlet in the chamber 13 and a side 11a opposed to the inlets, has an air flow rate regulating plate to be vertically fluctuated through a link 70 by a motor 8, and is controlled based on a detected result of the flow rate. |
