FAQ
1. What kind of food can I freeze dry with this machine?
You can freeze dry a wide variety of foods, including fruits (like strawberries, apples, bananas), vegetables (like peas, corn, carrots), meats (like beef, chicken, fish), seafood, dairy products (like cheese, yogurt), cooked meals (like soups, stews, pasta), and even pet food. Essentially, most foods with high water content can be preserved using this machine.
2. How does the freeze-drying process work?
The freeze-drying process, also known as lyophilization, involves three main stages:
Freezing: The food is frozen solid.
Primary Drying (Sublimation): Under a vacuum, the ice in the food sublimates directly from solid to vapor, removing about 95% of the water.
Secondary Drying (Desorption): The remaining bound water is removed by slightly raising the temperature, ensuring the food is thoroughly dry.
3. What is the difference between the DFD-04, DFD-06, DFD-10, and DFD-20 models?
The main differences are their drying capacity, number of trays, and physical size.
DFD-04: 4KG capacity, 4 trays, most compact.
DFD-06: 6KG capacity, 5 trays, slightly larger.
DFD-10: 10KG capacity, 7 trays, larger capacity for more serious users.
DFD-20: 20KG capacity, 10 trays, largest capacity for commercial or heavy home use.
Choose the model that best fits your production volume and available space.
4. Is the machine easy to operate?
Yes, the machine features an intelligent digital control panel that simplifies the complex lyophilization process into an easy, one-touch operation. The integrated digital display provides live updates on vacuum pressure, cold trap temperature, and drying status, making it suitable for users of all skill levels.
5. What is the material of the chamber and trays?
The chamber and trays are constructed from food-grade SUS304 stainless steel, ensuring the highest standards of hygiene, durability, and corrosion resistance.
6. How noisy is the machine during operation?
The machine is designed for quiet operation. The noise level is ≤ 60 dB, thanks to the high-quality branded vacuum pump that operates without oil mist, ensuring a cleaner and more comfortable working environment.
7. What is the minimum vacuum pressure and cold trap temperature?
For DFD-04 & DFD-06: Minimum vacuum pressure is 15 Pa, and minimum cold trap temperature is -40°C.
For DFD-10 & DFD-20: Minimum vacuum pressure is 15 Pa, and minimum cold trap temperature is -60°C.
These specifications ensure efficient and effective freeze-drying.
