How much space does a home freeze dryer require? Home freeze dryers typically have a footprint similar to a small chest freezer. Exact dimensions vary by model.
Freeze drying is fairly expensive due to equipment costs and to long processing times and related energy costs. Lyophilizers are sold by temperature range and capacity. Some freeze dryers also have more than one condenser to allow for almost continuous use.
Chemical products may also be freeze dried for stability and to make rehydration easier. Freeze drying can also be used more info to purify a substance by effectively removing solvent or to concentrate substances with low molecular weights.
Freeze drying or lyophilization differs from evaporation, which typically uses heat to eliminate moisture from a material. Freeze drying typically produces a high-quality product that maintains its original shape and can be successfully rehydrated. Commonly freeze-dried materials include:
