Freeze dryers; floor-model and bench-model. Freeze dryers are used to remove water from heat sensitive samples to preserve them from degradation (e.g. proteins, bacteria, foods). They work by freezing samples in a vacuum, which causes the frozen water to sublimate out of the sample. Manifolds and vacuum pumps are also available.

Freeze drying (also known as lyophilization) is a water removal process typically used to preserve perishable materials, with the goal of extending their shelf life and/or preparing them for transport. Freeze drying works by freezing the material, then reducing the pressure and adding heat to allow the frozen water in the material to change ...

Freeze-dried food not only retains its look and feel, but its chemistry as well, ... Oil-sealed pumps were the only game in town for years before the common freeze dryer. They provided a stable environment for removing excess moisture and generally were crucial to the freeze-drying process. But the high costs have always created an obstacle for ...

The freeze dryer (lyophilizer) is equipment that allows the drying of materials without the need to heat them. The physical principle involved in lyophilization is sublimation, which is the direct passage from a solid to a gaseous state, without passing through the liquid state. For the process to take place, the frozen product is dried under a ...

The freeze drying process includes the freezing of the food sample and subsequent applying a fine vacuum to the frozen sample. Under these conditions, the water in the food will sublimate, hence, the sample dries. In food applications, freeze drying is commonly used to make instant coffee and to dry and conserve fruits, vegetables or herbs.
