Convection-oven drying is controlled by gravity or mechanically controlled. This goal must be reached without incurring physical damage or undesirable surface modification of the part, promoting corrosion, or depositing soils back onto the part. While drying is important, high temperatures can cause surface damage or product deformation, so it’s also important to make sure the solvents at the temperatures used for drying are compatible with materials of construction. The aim is to assess and compare the technical cleanliness of parts produced by different manufacturers or at different locations. A particular manufacturing process might even require more than one type of drying. Gravity convection works on the principle that warm air rises, and while this method may be less expensive, there can be large temperature variations within the oven. “Drying food is one of humanity’s oldest ways of preserving food, because it is simple, low-tech and offers an excellent way to put aside the bounty of summer for the winter,” says Sharon Astyk, a farmer in upstate New York and author of Independence Days: A Guide to Sustainable Food Storage and Preservation” (New Society).
