Vacuum Drying and Making Stuff Hot in a Vacuum
Of course, we’d still want to retain the vacuum while doing said heating, which raises the question of how you best heat something that is inside a vacuum. Fortunately, this is a solved problem, with commentators to the previous article helpfully pointing to the existence of devices like vacuum ovens. Of course, you can either buy such a device and not worry your pretty little head about the finer details, or you can defy convention and build one yourself because you’re a rebel and really want to know how their internals work.

Vacuum Drying And Making Stuff Hot In A Vacuum No comments by: Maya Posch October 1, 2026 Title: Copy Short Link: Copy After previously exploring the impact of vapor pressure on the drying of desiccant and more, the conclusion was essentially that in order to drive moisture that’s not directly on a material’s surface out of it, you pretty much have to heat up said material to make the process not take forever. Of course, we’d still want to retain the vacuum while doing said heating, which raises the question of how you best heat something that is inside a vacuum. Fortunately, this is a solved problem, with commentators to the previous article helpfully pointing to the existence of devices like vacuum ovens.
