I am doing some research on vacuum oven, but I cannot find out any website/book to tell me the theory. To my knowledge, it works better than regular oven. However, I have no idea why it is. Please help

Vacuum Ovens works better than regular ovens because:

  • It removes the source of contamination. For example, heating metals to high temperature causes rapid oxidation in regular ovens which is undesirable.
  • It reduces the heat loss which is caused by convection.
  • It allows quick cooling of the product as there are no air to hold heat around product.
  • It allows precise control of uniform temperature in a certain area of oven. There's no air to screw it up.

doesn't reducing :heat loss which is caused by convection" contradict "quick cooling of the product as there are no air to hold heat around product"? – Yrogirg Dec 21 '12 at 15:02

I've put together an easy to ready pdf on how vacuum works. Check it out at: Hope it helps!
