Advances in the Modeling and Control of Freeze-Drying
Freeze-dryers are used in the manufacture of foodstuffs surgical spare parts, medical supplies, and in the production of pharmaceuticals. The particular desirable qualities conferred by the freeze-drying process are that the drying takes place at a relatively low temperature, so that thermal degradation is prevented, volatile materials other than water are largely retained, so that flavor qualities are unsurpassed, the final product, once packaged, is not subject to bacterial degradation at ambient temperatures, and the product is of low density and easily rehydrated.
