A drying apparatus for granular materials in which granular materials in a drying tank are heated and dried; the drying apparatus includes a moving mechanism to move the granular materials in the drying tank; and a control section to control the moving mechanism so as to move the granular materials in the drying tank upon determining that temperature of the granular materials around a heating portion in the drying tank exceeds a glass transition temperature.

A vertical oven for panels includes trays configured to support mainly flat panels arranged in a multiple of two stacks circulating in opposed directions, such as the first stack moving in an ascending direction and the second stack in a descending direction. The trays are arranged at a distance from each other and the movement of the trays is such that at least one every other tray is withdrawn from the circulation, doubling the distance between the trays.

A continuous-flow drying installation for drying workpieces, in particular vehicle bodies, having a heating zone enclosed by a first housing, in which the workpieces can be heated to a temperature T1, and having a cooling zone enclosed by a second housing, in which the workpieces heated in the heating zone can be cooled to a temperature T2<T1. The cooling zone is arranged completely above the heating zone. The continuous-flow drying installation additionally has a conveying zone enclosed by a third housing, in which there is arranged a transfer unit with which the workpieces heated in the heating zone can be transferred from the heating zone to the cooling zone, and a separating device which separates the heating zone from the conveying zone in an at least substantially air-tight manner but allows the workpieces to pass.
