Product Description

High Thermal Conduction Rate Vacuum Drying Machine

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 thefoaming 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.



Material to be dried

It is suitable for drying heat sensitive raw materials that can decompose or polymerize or deteriorate at high temperature.It is widely used in pharmaceutical,chemical,foodstuff and electronic industries.

Note:SZ water ring vacuum pump can be used together with mechanical pressure increasing pump in order to increase vacuum.

The vacuum dryer VTP is characterized by the following attributes and advantages:

  • Usable drying surface of 0,2 up to 17,0 m²
  • Heating and cooling with fluid heat transfer mediums
  • Excellent cleanability for both manual cleaning and CIP-cleaning
  • Evenly temperature distribution on all shelves
  • Excellent usability of the seal of the dryer
  • Special hinges provide a vacuum-sealed door seal

Equipment possibilities:

  • Heatable dryer door
  • Inclined bottom with integrated collecting pipe and discharge nozzle
  • CIP cleaning device for the repeatable cleaning which can be validated of the complete interior.
  • Carrier gas lance for the optimal distribution of the carrier gas via all shelves
  • Wall installation collar for the installation of the dryer into a clean room wall
For scale-up capable test applications, a vacuum dryer with 1,5m² usable surface is at disposal, with which tests can be carried out at our pilot plant stations or directly at our customer.
