Freeze drying, also known as lyophilization, is a dehydration process used to remove moisture to preserve products. In this process, the product is loaded into a freeze-dry chamber, containing the product and the freeze dry coil. The product is frozen at very low temperatures and the chamber is drawn in to a vacuum. Moisture sublimates off the product and collects as ice on the coil, effectively drying the product. Freeze drying in food processing is used to preserve and extend the shelf life of perishable products like fruits, vegetables, meats, and prepared meals while retaining their flavor, nutrients, and structure.
Colmac freeze-dry coils are custom configured to best fit each freeze dry application. We offer individualized connection locations, support structure, tube spacing, and defrost solutions.
