<p>The present invention describes apparatus and method for continuous drying, the method comprising cascading a material containing a substance capable of sublimation between a plurality of trays vertically stacked within a processing zone provided within a processing chamber, maintaining a substantially atmospheric environment within the processing zone at a temperature whereby the material dries within the environment, and contacting the environment containing the material with a drying agent to maintain the environment whereby the substance dries at substantially atmospheric pressure and at the controlled temperature. The cleanable rotary tray dryer of vertical housing comprising feeding funnel, rotating trays, drive for air distribution, wipers, heater, discharged funnel and trolley for rotary trays. The cleanable rotary tray dryer operates at atmospheric pressure using the principle of forced hot-air convection. The present tray dryer consists of a vertical housing that contains stack of shelves that rotate around set air. The shelves are divided into tray segments by radial slots that allow the material to be transferred down to successive shelves and ultimately discharged through discharged funnel to trolley.</p> |
