Freeze Dryer Overview
The advantages of a home-use small freeze dryer lie in its compact size, ease of operation, and low cost. Our home-use small freeze dryer has a freeze-drying area of 0.4m², with a batch capacity between 4–6kg. It is ideal for individual families, small food processing studios, food bloggers, and pet snack shops. The cold trap temperature can reach -60°C, and the vacuum degree can be lower than 2Pa, meeting the environmental conditions required for freeze drying.

Working Principle of Small Household Freeze Dryer
Pre-freezing stage
Before freeze-drying begins, the material is placed in the drying chamber, and its temperature is rapidly reduced to below the eutectic point temperature using a refrigeration system, typically reaching -40°C or lower.
Sublimation stage
After the material is completely frozen, the system activates the vacuum pump, reducing the chamber pressure to 13.3 Pa or lower, entering a high vacuum state. At this point, the saturated vapor pressure of ice is greater than the partial pressure of water vapor in the environment, so the ice sublimates directly from a solid state into water vapor. The sublimated water vapor is rapidly captured by the condenser and condenses again into ice on the surface of the cold trap at approximately -50°C.
Drying stage
After the sublimation stage, a small amount of tightly bound moisture still remains in the material. At this time, the equipment appropriately increases the temperature of the drying chamber while maintaining a vacuum, allowing this residual moisture to further vaporize and be removed.
Features of Small Freeze Dryer
- Small Size, Large Capacity: Compact design meets the needs of daily and commercial small-scale freeze-drying.
- Cold Trap System: The cold trap temperature can reach -60°C, rapidly capturing water vapor generated during sublimation. Vacuum Capacity: The equipment’s ultimate vacuum can reach below 2Pa, coupled with a pumping speed of 2L/s, providing an ideal environment for the sublimation process.
- Control System: Users can set parameters such as temperature, vacuum level, and drying time via a touchscreen, eliminating the need for complex operations.
- Nutritional Retention: Freeze-dried foods retain their original appearance, color, nutritional components, and flavor.
- Materials: Suitable for fruits, meats, vegetables, plants and flowers, instant foods, nutritional products, and health supplements.
Advantages of Small Home Freeze Dryer
- High Nutrient Retention: Freeze-drying technology works at low temperatures, so it preserves the cell structure of food and maximizes nutrient retention.
- Shelf Life: Freeze-dried foods have low moisture content and are less prone to spoilage.
- No Added Preservatives: Preservation is achieved through physical dehydration, making them healthier and safer.
- Placement: Home models have a small footprint, suitable for kitchens, balconies, studios, or small processing rooms.
- Operation: Users simply need to put in the materials, set the parameters, and start the equipment; the system will automatically complete the process.
