Freeze drying is the process of removing liquid from an item, such as food, pet food, chemcial products and so on, to help shelf life, reduce weight, and preserve quality. Due to the expense of freeze drying, it's the best used for premium products of premium quality.

Freeze drying begins with freezing the product in short time and subjecting it to vacuum pressure to remove the solvent content (usually water) from the product. The product is then heated, which allows the solvent to evaporate through a process known as sublimation processing.

For example, in the case of freeze dried food, a food item's texture, flavor, and nutritional content remain intact. Freeze-drying also greatly reduces the weight of the food, making it easier to transport and store.
