Vacuum Drying (Leather)

A method of drying leather taking advantage of the fact that moisture evaporates more quickly under vacuum. The wet leather is laid out on a wet steel plate (often slicked, a form of hand setting out) and the vacuum head brought down. After retanning and fatliquoring the leather can be dried to either 30% and then hang dried or in some circumstances fully dried direct. Drying only takes two to five minutes. A newer use of vacuum drying involves using a rubber base instead of stainless steel. While the leather is under vacuum this rubber base expands outwards, stretching the leather out from its centre. I have seen a page of newspaper pulled into jigsaw-sized pieces by this machine. It is not so good for taking out large amounts of moisture but good for the drying after conditioning and staking of soft leathers. Avoid using it just for area gain.
