BulletPoint1 : This Freeze dryer machine has undergone multiple experimental improvements, utilizing low temperatures and vacuum environments to effectively preserve the nutritional components, color, and containing materials such as fruits, meats, milk,and vegetables. It outperforms traditional drying methods, allowing for long-term storage, and can be rehydrated to restore the food to its pre-freeze-dried state. The Dry freezer machine has a minimum freezing temperature that can reach -60℃, vacuum < 15Pa, ensuring more thorough drying.
BulletPoint2 : The freeze dry machine is equipped with a 10-inch color touchscreen display that has been redesigned to support a 90° rotation, making it more user-friendly and easier to operate. The acrylic door allows users to observe the freeze-drying process in real-time, while the system supports data logging. Users can export freeze-drying curves and data for research purposes via USB ports located at the back of the Candy freeze dryer machine.parameters of the freeze-drying process in expert mode.
BulletPoint3 : The new Freeze dryer for food comes with two operating modes: Normal Mode and Expert Mode. In Normal Mode, users simply select a preset recipe to automatically initiate the freeze-drying program. In Expert Mode, users have the flexibility to independently adjust the freeze-drying process parameters to meet specific needs.
BulletPoint4 : The Home freeze dryer machine features four trays made of food-grade stainless steel, with dimensions of 55cm x 220cm x 2cm (21.65 x 8.66 x 0.79in) and a tray spacing of 4cm. The Small freeze dryer employs tray heating, ensuring uniform temperature distribution, strong moisture capture, and excellent freeze-drying results.
BulletPoint5 : To enhance operational convenience, the Freeze drier device has added a one-button defrost function. After the freeze-drying process is complete, users can simply press a button to initiate defrosting, allowing the internal ice to melt and drain out through the vent valve (drainage outlet), making it easy to clean.

ProductDescription :

The working principle of vacuum freeze dryer can be simply summarized as the following steps:

1. Pre-freeze-drying treatment: the material to be treated is pre-treated, usually including cleaning, cutting, etc., in order to dry more evenly during the freeze-drying process.

2. Freezing: Put the pre-treated material into the freeze dryer, and quickly freeze the material to a low temperature (usually between -50 ° C and -70 ° C) through the refrigeration system. In this process, the water in the material condenses into ice.

3. Vacuum environment: After freezing, vacuum is injected into the machine to reduce the air pressure (usually less than 0.1 Torr). A low pressure environment helps to lower the boiling point of water.

4. Sublimation: Under vacuum conditions, heat is transferred to the frozen material through heating disks or other heating methods. The ice sublimes directly from solid to gas, and the water does not pass through the liquid phase and is quickly removed.

5. Collection of water vapor: The water vapor produced in the sublimation process is guided to the condenser, where due to the low temperature, the water vapor is condensed into water and collected to prevent its reflux.

6. Drying completion: After a period of sublimation, the water in the material is basically removed, and the final product is dry.

Return to normal temperature: After drying, gradually return to normal temperature to complete the entire drying process.
