Vacuum tray dryer is the equipment with the help of which vacuum drying is carried out. Vacuum dryers are sometimes made up of cast iron, but most are made of stainless steel, so that they can bear the high vacuum pressure without any kind of deformation.
The oven is divided into hollow trays which increases the surface area for heat conduction. The oven door is locked air tight and is connected to vacuum pump to reduce the pressure.
The materials to be dried are kept on the trays inside the vacuum dryer and pressure is reduced by means of a vacuum pump. The dryer door is tightly shut and steam is passed through the space between trays and jacket so that the heat transfer occurs by conduction.
Water vapors from the feed is sent into the condenser and after the drying vacuum pump is disconnected and the dried product is collected from the trays
