Vacuum Shelf dryers provide rapid drying of heat sensitive, air-sensitive & pyrophoric materials, or materials that require drying without agitation. Heat sensitive materials can be dried at low temperatures under vacuum, since the environmental pressure is reduced below the vapour-pressure of the contained water or solvents. Oxidation or Contamination by Air is eliminated. Recovery of expensive solvents can be virtually complete. Hollow Fibers, Medical Devices, Chemical Salts, Fine Chemicals, Dyes, Glandular Products, Pharmaceuticals and Food Extracts (Gluten, Glues, Pepsin), Rubber Explosive, etc. are ideally suited for drying in this manner.
Principally, Drying under vacuum is environmentally friendly because the Evaporated Solvents can easily be re-condensed. These solvents can then either be recycled or disposed of without any problem.
Drying of solvents in Ex-proof ovens may solve the safety problem in the oven but not the environmental aspect. The solvent vapour is blown out of the oven through the exhaust system Furthermore, there is a risk of uncontrolled mixture formation.
