What are freeze dryers?

Freeze dryers (lyophilizers) are vacuum dryers used for freeze-drying (sublimation drying, lyophilization). In a freeze dryer, a product to be dried is quickly brought into a frozen state. The water is then removed by sublimation and directly passed from the solid-state (ice) to the vapor state. This drying method is very gentle on the product and ensures that qualities such as organic cell walls, vitamins, flavours or natural colour are largely retained.

Industrial lyophilizers for sale at Foeth

Freeze-dryers are used in the food technology and chemical industries, as well as in the pharmaceutical and cosmetics industries. Most lyophilizers are built using oil-based vacuum pumps and the lyophilisation process itself is carried out under pressure, consisting of primary and secondary drying. Products dried in a freeze-dryer retain only up to 4% of their water content, which effectively slows down the spoilage process of the dried material and reduces its susceptibility to microbial attack. The advantage of the freeze dryers in the Foeth collection is the high quality of the machines and the adaptation to the freeze-drying process of different products. The machines available include Boc Edwards lyophilizers and Christ lyophilizers. In addition to lyophilizers, autoclaves, filters, compactors,mills or mixers are also available at Foeth.
