The programmable laboratory small freeze dryer uses a cold trap with an ice capture capacity of up to 8kg, and the ice capture surface area is more than twice that of similar freeze dryers, which can condense sublimation water more quickly.

The sample tray heating function (standard for pilot and production freeze-drying machines) can accelerate and control the sublimation speed of ice crystals in the sample, achieving rapid freeze-drying effect. The 24-hour freezing capacity can reach 6kg, greatly reducing the experimental time.

The control system of a programmable laboratory small freeze dryer mainly has the following characteristics:

1. PLC control system+touch screen control system;

2. The LCD large screen displays important process parameters such as cold trap temperature, laminate temperature, product temperature, system vacuum degree, process time, alarm information, etc;

3. Can store multiple freeze-drying formulas, each containing 10 or more steps;

4. There are two operating modes to choose from: semi-automatic mode and fully automatic mode;

5. It can automatically turn on. If an unexpected power outage occurs during operation, the freeze-drying machine will automatically save the freeze-drying program data and continue to run the unfinished freeze-drying program after detecting power restoration;

6. The system has sound and light alarm function. Any abnormality in the system will automatically sound an alarm, and the cause of the fault will be automatically determined. The user will be informed of the alarm reason in digital form on the screen;

7. Can be equipped with LYOLOGGER software, which can be connected to a computer to generate freeze-drying curves and save freeze-drying data.

8. Multiple cavity configurations are available to meet the various needs of scientific research users;

9. Can achieve pre freezing of freeze-dried samples;

10. Layer heating technology can achieve accurate temperature control of layer boards;

11. Two PT 100 temperature probes are equipped inside the chamber to monitor the temperature of the laminated board and freeze-dried product, respectively.
