Product Overview

Key Features

Vacuum Tray Dryer



Vacuum Tray Dryer is used mainly for drying of high grade,
temperature and oxygen sensitive products. Vacuum Tray Dryer is 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 pomposity.


Capacity


Standard models range from 4 trays to 48 trays.








  • Vacuum
    Tray dryer is the most commonly used batch dryer. They are box-shaped
    and loaded and unloaded via a door. Inside are several heating plates
    mounted one above the other on which the product is placed in trays.
  • The
    bottoms of both heating plates and trays should be as smooth as
    possible to permit optimal heat transfer between plates and product.
  • The medium flowing through the heating plates is water, steam or thermal oil.
  • The distance between the heating plates is determined primarily by the surface loading and the foaming of the product.
  • To
    avoid retrograde condensation the cabinet walls are indirectly
    preheated by the heating plates. Next, the product is introduced and
    heated at atmospheric pressure. Only after all individual product trays
    reach the same temperature the cabinet is evacuated and drying can
    start.
  • The preheating phase is very important in
    order that the drying curve and 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 and in the final
    drying phase vacuums of only few mbar abs are reached.
  • Heating
    temperatures are normally in the range between 800C and 1100C.
    Depending on product and surface load, drying takes from a few hours to
    1 to 2 days.
  • For some products the vacuum and
    temperature profiles are automatically controlled in order to prevent a
    pass over of the critical product temperature.
  • The
    dimensioning of the vacuum system is an important factor in the design
    of drying cabinet systems. If for example vigorous foaming of the
    product is desired, evacuation to the operational vacuum level must
    take place very quickly.
  • Vapours produced during
    drying are taken out direct, or via a steam jet compressor to a surface
    condenser in which the vapours condensate. The non-condensable vapours
    are extracted by the vacuum system.
  • On completion of the drying, the product can be cooled by circulating of cooling water through the heating plates.
  • Often
    vacuum drying cabinets are supplied to new, small production operations
    in newly opened markets. Following successful development of the
    market, it could be worthwhile to replace the cabinets through
    continuous vacuum belt type dryers.
