FREEZE DRYING PROCESS

The vacuum freeze drying process calls for very sophisticated equipment, and is especially suitable for large numbers of wet books, records, as well as coated paper. Books and records are placed in a vacuum chamber frozen. The vacuum is pulled, a source of heat introduced, and then dried at temperatures below freezing. Then the physical process known as sublimination takes place, which is when ice crystals vaporize without melting. This means there is no additional swelling or distortion beyond that incurred before the materials were placed in the chamber. Many coated papers can be difficult to dry without them sticking together once they are wet. It's is nearly impossible to determine which papers will block, so all coated papers should be treated the same way for the purpose of vacuum freeze drying: before any drying takes place, and ideally within 6 hours of becoming wet, materials should be frozen below -10 degrees. Although this method may initially appear more expensive because of the specialty equipment required, the results are more often so satisfactory that additional funds for rebinding are not necessary. Mud, dirt and soot will be lifted to the surface, making the cleaning time less consuming as well.
