Freeze Drying Applications

Freeze Drying Applications

Freeze drying and lyophilization works well on almost all industries, this because of its unique working process. Freezing the material, and then reduce the surrounding pressure to allow the solid water sublime directly from solid phase to gas. During the process, most time, materials temperature are below zero. So, freeze drying has less impact on product chemical properties.

One the other hand, freeze dried products do not need to be refrigerated or preserved with chemicals, they can be reconstituted quickly and easily by adding water. The ulta low storage cost, nutritious ingredient and the highly prolonged shelf life makes people love freeze dried products more than other dehydrated.

Food Freeze Drying
Food Freeze Drying
Freeze drying perfect fit food preservation. Make it light weight, easy storage and transport. Freeze-dried foods do not need to be refrigerated or preserved with chemicals, can be reconstituted quickly and easily by adding water. Examples: Cooked meals, Soup, Porridge, Noodles, Instant Coffee, Meat, Seafood etc.
Fruit and Vegetables
Fruit and Vegetables
Freeze drying is a good way to preserve fruits and vegetables. Turn them to light weight and easy storage fruit snacks. Since freeze drying only remove water, and nutrients, vitamins, flavor, structure and tastes are well preserved. So lyophilized fruits are healthy to eat. Examples: Apples, Berries, Pineapples, Peach, Cherries, Banana, Melons etc.
Dairy Freeze Drying
Dairy Freeze Drying
Freeze dried dairy is nutritional than other dehydration method. Especially fit formula baby milk powder production, freeze drying is highly recommended. Freeze dried dairy products are light weight, easy transport and no critical requirements to storage environment. Examples: Milk, Yogurt, Ice cream, Cake, Probiotics and other milk based products.
Pharmaceutical Freeze Drying
Pharmaceutical Freeze Drying
Lyophilization has been used in many pharmaceutical's production projects. Freeze drying heat sensitive drugs at low temperature, great improve the stability and storage of labile drugs. Keep the biological activity of them and extend shelf life. Examples: Pills, API, Injectable formulations, Penicillin, Vaccines etc.
Pet Food
Pet Food
Freeze drying of pet food well keep the protein which guarantees healthy growth of dogs or cats. Frozen pet foods are dehydrated under vacuum environment and minus temperature, water removed by sublimation technology. Examples: Chicken breast, beef, mixtures etc.
Biological Freeze Drying
Biological Freeze Drying
Freeze drying is widely used in biologicals areas. This low temperature drying method guarantees the biological activity and storage stability. Offers safe storage environment and transport. Examples: Venom, Plant extracts, Tissues, Microorganisms, Blood, Bacteria, Specimen etc.
Chemical Freeze Drying
Chemical Freeze Drying
Freeze drying method is necessary for many chemical products, like graphene have to be freeze dry to get a better quality and as a qualified precursor.
Lab Research
Lab Research
Freeze drying is an ideal way to store samples without being degraded. Microorganism and structure are preserved for deep study. Research institues and laboratories use freeze drying technology a lot.

Freeze Drying Process

Frozen products are placed in drying chamber, vacuum pump running to pull down and maintain the chamber pressure, vacuum environment created and the solid water in raw product will start sublimate. An ice condenser is use to collect the sublimated vapors, store it in form of ice. After drying finish, defrost the ice and discharge out, prepare another batch.

The Vikumer freeze dryers are fully automatic working, a PLC and user friendly HMI based controller is use to operate and monitoring the freeze drying system.
