Vacuum Drying Chamber
Bay Area Test Equipment Inc is one of the leading vacuum drying chamber manufacturers and suppliers,Website:http://www.bacldesign.net, welcome to buy and wholesale cheap and best vacuum drying oven from us. Vacuum Chamber Vacuum chamber is designed to dry by using vacuum and heat to remove bulk and absorbed water or other solvents from a product. Application Vacuum is oftenemployed as a process for removing bulkand absorbed water?(or other solvents) from a product. Combined with heat,?vacuum?can be?an effective method for drying. High degrees of dryness can be attained at?relatively low temperatures. This allows for fast and effective?drying of temperature sensitive products. Lowermoisture content can be achieved when using vacuum and heat than can beachieved with heat only(particularly with parts that are porous or have a veryhigh surface?area). Additionally, drying under a vacuum can prevent oxidation of?sensitive product that cannot be dried in the presence of air. Vacuum drying systems can also recover the solvent?that?is removed from?the product, if required. Often?the part to be dried is placedinto a vacuum drying chamber. However,if the part can withstand, and is designed for vacuum, the?inside of the part can?be evacuated and dried without the use of a vacuum chamber. Product Description? A vacuum dryingsystemconsists of a vacuum chamber, amechanical vacuum pump with gauge?and valves as well as a?source for providing heat to the product?to be dried. Both oil-sealed and oil-free (dry)mechanical?vacuum pumps can be used. .A condensate?trap (typically?cooled?to very low temperatures) is also used to pump and trap the?liquid(s) to be removed.?Base pressures?of less than 0.1 Torr are often?required, depending on?the?liquid to be removed and the temperatures. Care?should be taken to protect oil-sealed pumps from the liquid and operating the pumps?properly to minimize the impact?of the liquid vapors being ingested into the pump (often with the use of a gas ballast and/or gas purge). The vacuum drying process ofteninvolves multiple stepsof applying heat?and vacuum. Reducing the pressure (applying vacuum) at the surface of a liquid (such as water)?will allow the liquid to evaporate without elevating?the temperature. The evaporation of the liquid will continue until the?partis dried or until enough heat is removed (through evaporation) that the remaining liquid freezes. At this pointthe drying process continues as?sublimation which is much slower compared to evaporation. In general, this?is not desirable. The purpose of heat is to maximize drying while preventing?freezing of the liquid. There are several methods of applying heat to the product beingdried. Some products have temperature limitations which may impact which methods may be employed. These methods include: ?Preheating theproductusing avarietyof methods prior to placing into?the vacuum chamber. ?Preheating theproductin a speciallydesigned vacuumchamber that is configured to provide convection heating as well as vacuum.
