Freeze Drying

Freeze drying, also known as lyophilization, is a low temperature dehydration process. A completely frozen sample is placed under vacuum to remove water or other solvents from the sample, allowing the ice to change directly from a solid to a vapor without passing through intermediate liquid phase. The low temperature involved in this process is ideal for the long-term preservation and maintaining the integrity of the sample’s biological, chemical, and structural properties.

We use high quality freeze drying for sublimation of both water and organic based solvents for pharmaceutical, food industry, technology, and medical samples. The samples from any of these industries are dehydrated and sealed to increase the shelf life either for storage or transportation while the maintaining the original properties.

The apparatus keeps frozen samples under vacuum and traps the released moisture and volatile contaminants at -70°C and effectively dry anything at room temperature. This is extremely useful when handling heat sensitive organic materials, biological, nutraceutical, food, and medical samples.

For pharmaceutical industry, we use freeze drying to preserve the samples. The samples are well sealed after the removal of water contents, these samples can then be stored, shipped, and later reconstituted to its original form for usage. Active Pharmaceutical Product Ingredients (APIs) are synthesized and then freeze drying is used to achieve chemical stability for long period storage.

We use freeze drying within the food industry to extend the shelf life of food products while retaining the original quality and flavors. With conventional drying methods, food products such as seasonal fruits, vegetables, snacks, and coffee can degrade in quality while Freeze-drying operates at low temperature, so it results in the highest quality of foods by preserving structural integrity, flavors, color, taste, and other essential components. Berries, chocolates, bars, meat products, coffee, snacks.

Various other chemical syntheses involve freeze-drying to make more stable products, or easier to dissolve in water for later use. It is also required in medical fields for samples that are heat-sensitive, such as proteins, enzymes, and amino acids.
