Main applications for Coolmachs FD**0 freeze dryer
Freeze drying is used to preserve food, and because of its unique characters, the process has been popularized in the forms offreeze-dried ice cream, an example of astronaut food initially.
 
And with the development of this technology and decrease of processing cost, it is nowadays also widely used to produce many different products such as various vegetables and fruits berries, strawberry, durian, apple, corn, pet food, convenient soup and many more. Because of its light weight per volume of reconstituted food, freeze dried product is also popular and convenient for hikers. More dried food can be carried per the same weight of wet food, and has the benefit of "long life" compared to wet food that tends to spoil quickly. The hikers then reconstitute the food with water available at point of use. Instant coffee is sometimes freeze-dried, despite the high costs of the freeze-driers used.
 
Freeze-dried fruits are used in some breakfast cereal or sold as a snack, and are an especially popular snack choice amongtoddlers, preschoolers and dieters, as well as being used by some pet owners as a treat for pet birds or koi fish.
 
Culinary herbs are also freeze-dried, although hot air dried herbs are far more common and less expensive.
 
And freeze-dried instant soup is also very popular in the meals provided on air plane.

Advantages of Freeze dried products
There are several advantages of freeze-dried products when compared to regular hot air dried products.
 
1) The freeze dried products have long preservation time.If a freeze-dried substance is sealed to prevent the reabsorption of moisture, the substance may be stored at room temperature without refrigeration, and be protected against spoilage for many years. Preservation is possible because the greatly reduced water content inhibits the action of microorganisms and enzymes that would normally spoil or degrade the substance. 

2) Easy transportation.With light weight and well packed freeze dried products can be easily transport by normal containers or any other transportation method. No needs for cold storage facilities therefore save a lot of cost for transportation. 

3) Better quality products.Freeze drying causes less damage to the substance than other dehydration methods using higher temperatures. Freeze-drying does not usually cause shrinkage or toughening of the material being dried. In addition, appearance, flavors, smells and nutritional content generally remain unchanged, making the process popular for preserving high quality food. 

4) Extremely high rehydration capacity.Freeze-dried products can be rehydrated (reconstituted) much more quickly and easily because the process leaves microscopic pores. The pores are created by the ice crystals that sublimate, leaving gaps or pores in their place. This is especially important when it comes to instant or convenient food uses.
