Coffee Vacuum Freeze Dryer

Application of freeze dryer

Freeze drying is suitable for fruit and berries as well as for cooked meat or vegetables. Herbs and spices are also preserved through freeze drying by removing all but a few percent of the water from these products. The best-known freeze-dried food is probably soluble (instant) coffee. Many ready meals, which are only dissolved in boiling water for preparation as granules or in powder form, have been freeze-dried. In principle, food can also be dried in a simpler way, for example through desiccation. However, this has the disadvantage of changing the structure and appearance of the food. In addition, aromas can react with atmospheric oxygen, which has an effect on the taste.

During freeze drying, the structure remains unchanged and the dried cells can easily absorb water again during preparation. By drying under vacuum, the aromas are largely preserved.

Applications of vacuum dryer

Vacuum dryer can be used to dry heat sensitive hygroscopic and toxic materials. If the feed for drying is a solution, it can be dried using vacuum dryer as the solvent can be recovered by condensation. To improve the quality of products, such as for fruit preservation, hybrid drying combining osmotic dehydration followed by heat pump drying and microwave-vacuum drying proved effective.

Vacuum Dryer For Vegetables

Examples for the use of Busch vacuum technology in freeze drying applications 

Busch vacuum pumps are used worldwide for the freeze drying of foodstuffs like fruits, soups, and noodles. Our COBRA, R5, and vacuum boosters are employed in freeze drying of instant coffee, which is a harsh application due to the risk of carryover of coffee into the vacuum pumps. They are also used for the freeze drying of sensitive biologically active substances in the pharma and biopharma industries. A more exotic application is the drying of water-damaged old books and scrolls. Busch vacuum pumps have even been used to dry a longship. The latter was brought to the surface from the bottom of a lake where it had been buried for centuries.
