Factory Direct High Temperature Forced convection Vacuum Drying Oven with program control
5.1 Application:
Application
Vacuum oven are mostly used for drying, baking, sterilization of non - volatile items and heat treatment test -for mining enterprises, schools, medical and scientific research.Expecially for simultaneous drying of different kinds of polymers in small quantities for drying materials for trial molding. They can also be applied in electronic engineering, electroplating, and pharmacy, paint baking, printing industries, etc. for preheating or drying related products.
Features
● Silicone sealing pressure pad, ensure the perfect tightness inside the box
● Glass fiber insulation, provide efficient thermal insulation, energy-saving effect
● Heating plate installed in a box in a four - sided, ensure temperature uniformity
● Digit temperature sensor, ensure work stably for given vacuum conditions
5.2 Description
A vacuum drying system consists of a vacuum chamber, a mechanical 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 often involves multiple steps of 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 part is dried or until enough heat is removed (through evaporation) that the remaining liquid freezes. At this point the 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 being dried. Some products have temperature limitations which may impact which methods may be employed. These methods include:
•Preheating the product using a variety of methods prior to placing into the vacuum chamber.
•Preheating the product in a specially designed vacuum chamber that is configured to provide convection heating as well as vacuum.
