WebFreeze drying, also known as lyophilization or cryodesiccation, is a low temperature dehydration process that involves freezing the product and lowering pressure, removing … WebA gas ballast left open for extended periods of time. A leak in the freeze dryer or the pump itself. In freeze drying a good vacuum pump should be able to attain approximately 10mT in a clean, dry and refrigerated freeze dryer. When the freeze dryer is isolated from the pump the leak rate of the dryer should be less than approximately 30 mT/hour.

WebThe freeze dryer’s cold condenser provides a surface for the water vapor to adhere and solidify. The condenser also protects the vacuum pump from the water vapor. About 95% of the water in the material is removed in this phase. Primary drying can be a slow process. Too much heat can alter the structure of the material.
