Products Features

1. Adopting a drying curve optimization control algorithm.

2. It has a robust ice trapping capacity and high drying efficiency.

3. The temperature sensor and control system can precisely regulate the partition temperature,

with a temperature control precision of ±1 ℃.

4. Multiple sets of process formulas can be saved, resulting in a high rate of process optimization.

5. Operation data, curves, and alarm records can be recorded and saved for up to 2 years.

6.The minimum service life of the equipment is 20 years.

7.It features a high degree of automation: once the freeze-drying process recipe is input, the food freeze-dryer initiates automatic operation, transitioning from the pre-freezing stage to the first sublimation drying stage. Following the completion of the first sublimation drying stage, it proceeds to the second drying stage until the freeze-drying process is finished.
