This vacuum tray dryer is a drying oven that can quickly and effectively dry raw materials under vacuum conditions. This process is superior compared to hot air drying ovens because they can dry at low temperatures, which is desirable for sensitive materials. The square vacuum dryer can use hot water, steam, or conduction oil as the source of heat in the system. Whatever the heat source, the heating unit is behind a heat jacket so that the raw materials are not directly in contact with the heating medium.
