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.
