More information about the Dohmeyer DOH-CXP-CRF-4000-LIN-2020

Freeze dryers, also known as lyophilizers, are machines used to remove moisture from various substances through a process called lyophilization. This process involves freezing the material and then subjecting it to a vacuum, causing the frozen water to sublimate directly from solid to gas without passing through the liquid phase. The result is a dry and stable product that can be stored for extended periods without degradation. The freeze drying process consists of three main stages: freezing, primary drying, and secondary drying. In the freezing stage, the material is cooled to a very low temperature, typically below -40°C (-40°F), to solidify the water content. This prevents the formation of ice crystals, which can damage the structure of the material. After freezing, the primary drying stage begins. The pressure is reduced, and heat is applied to the material, causing the frozen water to sublimate. This process can take several hours to several days, depending on the material and its moisture content. The primary drying stage is crucial for removing the majority of the water from the material. The final stage, secondary drying, involves further reducing the moisture content to achieve the desired level of dryness. This is done by increasing the temperature slightly and continuing to apply a vacuum. The duration of this stage varies depending on the material and desired moisture level. Freeze dryers are commonly used in various industries, including pharmaceuticals, food processing, and preservation of biological samples. They are particularly useful for preserving heat-sensitive substances, as the low temperatures used in the process help maintain the integrity of the material. The resulting freeze-dried products have a longer shelf life, retain their original properties, and can be easily rehydrated when needed.
