Drying under vacuum isa widely used thermalprocess in many bran-ches.
The objective of this pro-cess is to gently dry highquality products contai-ning water or solventswithout modifying theproduct characteristics.
During vacuum drying,the overall pressure inthe drying oven is re-duced so that water orsolvents start changingfrom the liquid to thevapor phase at low tem-peratures.
The drying process canbe optimized by carefulcontrol of the heat andpressure.
As a matter of principle,a vacuum drying systemconsists of a drying ovenwith heating system, avacuum pump assemblydesigned specifically forthe drying process and amatching control.

The patented vacuum drying oven Type VSD(VSD = Vacuum SystemDreisbach) ensure usersof optimum cleaning,offering ideal conditionsfor a GMP FDA-approvedprocess.
The heated shelves andchamber walls merge with-out joints subdividing theinterior into individualcharging chambers. Allsur faces in the productarea are visible and opti-mally suited for use of aCIP cleaning device (CIP = Cleaning In Place).
VSD vacuum drying ovensare preferred in the chemi-cal and pharmaceutical
industry, process techno-logy and in the foodstuffsbranch where clean, con-tamination-free conditionsare required.
This is the reason why current certificationaccording to the EHEDGGuidelines was applied for in 2002. (EHEDG = European Hygienic EquipmentDesign Group.)
Moreover, we provide sup-port in completing yourDQ, IQ, and OQ documen-tation with the requiredtests and certificates.
Patented SystemPerfect Cleanliness
Description of VSD Principle
All surfaces in the product chamber can bechecked visually and manually.
Absolutely joint-free production chamber without concealed surfaces and corners.
No passages in the interior for feed andreturn of heating media.

Vacuum Drying Oven, VSDPatented as well as EHEDG-approved
Surfaces and walls are double-walled, all corners arerounded. Product compartment is completely view-able. Easy cleaning. High quality and corrosion-resis-tant stainless steel.
This vacuum drying ovenis suitable for setup andoperation in explosion-hazard areas.
All parts of the vacuumchamber coming intocontact with the productconsist of high qualitystainless steel or specialmaterial such as Hastel-loy, Inconel or Titanium.
The sur faces are groundand polished.
The shelves and ceilingare designed with doublewalls. Heating is accom-plished with hot water orthermal oil.
The heated shelves andchamber walls merge without joints subdividingthe interior into individualcharging chambers.
The front side of the vacuum drying oven isequipped with a circum-ferential mounting framefor wall installation; theframe is welded tightly tothe vacuum chamber.
The vacuum drying oven is tested for leakage with helium or using the pressure increase method.This test is confirmed by a certificate.
Design features of the VSD
The door suspension is equipped with adouble joint hinge toensure that the doorseal makes propercontact without deformation of the O-ring.
The door is equippedwith a circumferential,temperature-resistantround seal.
