Microwave drying of hides under vacuum in tanning equipment

By providing a hide processor or tanning drum with appropriate equipment for applying vacuum and microwave energy concurrently, these tanning machines become a versatile means of drying to yield dry hides that contain no salt yet store better than salted hides. In this novel process, fresh hides are loaded into the tanning machine where they are washed, demanured and then dried in situ under vacuum with concomitant application of microwave energy. Because the dried hides thus obtained are soft and pliable, they can be mechanically fleshed or shaved to remove the subcutaneous tissues rich in collagen and fat. Alternatively, the hides may be first dried in the tanning machine to below 35% moisture content and degreased using a solvent such as hexane. The solvent remaining in the hides after decantation of the unabsorbed liquid is vaporized at low temperature using vacuum and microwave energy. The hides are then dried in situ to the desired final moisture content. By shaving off the subcutaneous tissues of these hides a dry, fat-free, valuable undenatured collagen product is obtained. If the hides are unhaired before drying, they may be shaved and then accurately split. The process is also suitable for removing hair and fat from hide trimmings to obtain a valuable undenatured collagen product and fat. Furthermore, it can be used to remove fat from connective tissues and other animal offal containing no hair yielding a dry undenatured collagen product.
