What is a Vacuum Freeze Dryer Machine?
A freeze dryer is one of the most common and essential drying
equipment, which is used to dry food ingredients by utilizing the
freeze drying method.
It usually consists of four components, including a drying chamber,
a vacuum pump, a heat source and a condenser.
Freeze dryer can be divided into commercial, laboratory,
industrial, and household. It is widely used in food,
pharmaceutical and other industries.
freeze drying is based on
Vacuum freeze-drying technology, also known as sublimation drying,
is a method of pre-freezing a small amount of material and then
converting it into water to sublime under vacuum. Therefore,
freeze-drying technology is widely used in the fields of medicine,
food, chemical industry, biological products and so on.

To freeze dry food using a vacuum freeze dryer machine, you can
follow these steps:
1. Prepare food:
- Prepare the food to be freeze dried. For example, wash and cut
fruits and vegetables or squeeze juice, etc.
- Put the prepared food into the tray. Fruit pieces are placed
directly into the tray and then the tray is placed into the freeze
dryer. There needs to be a gap between the food. Liquids need to be
poured directly into the tray in the freeze dryer, and then we push
the tray into the freeze dryer. Be careful not to freeze dry more
food than the machine can hold
2. Prepare before freezing:
- Place the frozen food into the freezer compartment of the freeze
dryer and lock the door. Make sure your freeze dryer is pre-cooled
and set up.
- Set the required temperature and time parameters according to the
instructions of the freeze dryer. These parameters may vary
depending on the model of the freeze dryer, so be sure to consult
the user manual of the device for accurate information.
3. Start the freeze dryer:
- Start the freeze dryer to start the process. During the freezing
and dehydration process, the food will gradually condense and lose
moisture.
4. Complete the process:
- The freeze dryer will complete the work within the set time. When
finished, your food should be completely freeze-dried.
- Turn off the freeze dryer and wait for a few moments for the
freeze-dried milk to return to room temperature.
5. Storage:
- Store the freeze-dried milk in a dry, airtight container with an
oxygen absorber to prevent oxidation and moisture.
- It is best to store it in a cool, dark place to extend its shelf
life.
