Vacuum Tray Dryer

Used mainly for drying of high grade, temperature and oxygen sensitive products highly suitable for drying hygroscopic substances, which are dried to very low residual moisture, content level. Frequently vacuum drying cabinets are the sole possibility for drying lumpy, glutinous products or products of low pompality.
Capacity :- Standard models range from 4 trays to 96 trays.
Bodies may be of cindrical or rectangular cross section both shelves and body are heated with controlled circulation of hot water, steam or diathermic fluid.
Vacuum tray dryer is the most commonly used batch dryer. They are box-shaped and loaded and unloaded via a door ( two doors on the larger models). Inside are several heating plates is water, steam or thermal oil. The distance between the heating plates is determined primarily by the surface loading.
The preheating phase is very important I order that the drying curve & the foaming of the product is identical throughout the cabinet. During the main drying phase the vacuum is in the range of 40 to 80 mbar abs & in the final drying phase vacuums of only few mbar abs are reached.
The dimensioning of the vacuum system is an important factor in the design of drying cabinet systems.
Available capacity :-  Dryer range from 4 trays to 96 trays
