A bin and method of use for containment and delivery of particulate materials has: a) a housing; b) a particulate materials support plate within the housing, the support plate having a porous structure allowing air flow therethrough; c) the support plate having a central area elevated away from the bottom of the housing and surrounding sides; d) an air flow area between the bottom of the housing and the support plate; e) a particle drop region surrounding the sides of the support plate; and f) a sealing and/or opening component within the particle drop region that seals and opens a particle drop path between the support plate and the side walls of the housing. The sealing and opening component has an expanded position when sealing the particle drop region and is in a retracted position when opening the particle drop region to particulate material passage.

A spray drying apparatus has a spray drying chamber; a liquid feed atomizer; a drying gas disperser; a perforated bottom; and a plenum chamber with an outlet below the perforated bottom. At least one guide plate is provided in the plenum chamber to direct gas, which is passing through the perforated bottom into the plenum chamber, towards the bottom of the plenum chamber. The guide plates have lower edges extending on average down to at least half-way between the perforated bottom of the spray drying chamber and the bottom of the plenum chamber.

A device for controlling the temperature of workpieces, in particular for drying vehicle bodies, having a housing, a temperature-controlling tunnel accommodated in the housing, and a temperature-controlling system for controlling the temperature of workpieces. The temperature-controlling system includes a full-space temperature-controlling device which can control the temperature of a workpiece as a whole, and a local temperature-controlling device which can control the temperature of locally delimited regions of the workpiece and which comprises multiple temperature-controlling units that can be activated and actuated independently of one another for this purpose. The full-space temperature-controlling device and the local temperature-controlling device are provided in the temperature-controlling tunnel such that a workpiece at least within an active section in the temperature-controlling tunnel can be under the influence of both the full-space temperature-controlling device as well as the local temperature-controlling device. A system and a method for controlling the temperature of workpieces are additionally provided.

A moisture control and drying apparatus includes a heating chamber having a bottom wall and a continuous upstanding side wall that together define an interior area. A heating assembly situated in the interior area of the heating chamber is configured to emit heat when actuated. A support platform is coupled to a peripheral upper edge of the heating chamber that blocks access to the interior area of the heating chamber, the support platform defining a water collection channel about an outer edge thereof. A transparent evaporation cover includes a closed top cap and a continuous side wall extending downwardly therefrom that has a lower edge removably nested in the water collection channel of the support platform and defines an open bottom. The support platform defines apertures so that heated air in the heating chamber is in fluid communication with the interior space defined by the evaporation cover.
