China Supplier -80℃ Quick Freezing Round And Rectangular Vacuum
Cabinet Drying Machine
Product Application:
Freeze-drying is a low-temperature dehydration process that
involves freezing a product, reducing the pressure, and removing
ice (moisture) by sublimation, the transformation of a substance
from a solid state to a vapor without passing through an
intermediate liquid phase. Freeze-drying produces a high-quality
product because the entire process is carried out at low
temperature and pressure by applying a vacuum at a vacuum below the
triple point. The original shape of the product is maintained and
the rehydrated product is of excellent quality.
The vacuum dryer is composed of a refrigeration system, a vacuum
system, a heating system, and an electrical instrument control
system. The main components are drying box, water trap (cold trap),
refrigeration unit, vacuum pump, heating/cooling device, etc.
The difference between vacuum drying and freeze drying:
Vacuum drying mainly for raw products that not very heat sensitive.
Freeze drying mainly for areas where nutrition is need to preserve.
Brief description of freeze-drying process:
a. Raw material prepared
b. Loading and conveying
c. Freezing
d. Delivering to Storehouse
e. Vacuum Drying
f. Discharging
g. Paking
Advantages of Vacuum Freeze Drying Machine:
Compared with canned food and frozen food, the recurring cost of
freeze-dried food transportation and storage is lower, and the
high-quality and high added value of freeze-dried food can make up
for the disadvantage of high cost, especially for high prices. For
food raw materials, the cost of freeze-drying does not account for
a large proportion of the sales price of its products. It maintains
the original shape, color, aroma, taste and nutrition of the food.
It has the advantages of good rehydration, light weight, and
storage at room temperature.
The price of freeze-dried food in the international market is 4-6
times that of hot air-dried food, and 7-8 times that of
quick-frozen food. It has an irreplaceable position in special
occasions such as mountaineering, navigation, exploration, and
military field operations, and is also the main food for astronauts
in space. It can be seen that the international market for
freeze-dried food is growing. People have higher and higher
requirements for food quality, especially for high-quality baby
food and health food. Dramatic increase.
