Weight Reduction. All fresh foods contain water, which is its main source of weight (fruits are more than 80 to 90% water). However, during drying about 98% of the moisture in the food substance is removed, which reduces the weight by as much as 90%, making it lighter to carry backpacking. Aside from freeze-dryingâs use in backpacking and camping, the military also freeze-dries foods to make it easier for one person to carry large amounts.
Wood drying (also seasoning lumber or wood seasoning) reduces the moisture content of wood before its use. When the drying is done in a kiln, the product is known as kiln-dried timber or lumber, whereas air dying is the more traditional method. Wood burning: when wood is burned, it is usually best to dry it first. 2  Damage from shrinkage is not a problem here, and the drying may proceed more rapidly than in the case of drying for woodworking purposes. 3  Moisture affects the burning process, with unburnt hydrocarbons going up the chimney.
