HT-05FA in situ silicone oil freeze-drying machine
Vacuum freeze dryer is widely used in meqdicine, pharmacy, biological research, chemical industry, food and other fields. The freeze-dried articles are easy to be stored for a long time. After adding water, they can return to the state before freeze-drying and maintain the original biochemical characteristics.

Main features:
- the transparent door of drying bin is made of aviation acrylic material, with no adhesion, high strength and no leakage. The change process of materials can be clearly observed during operation.
- Imported brand compressor, stable and low noise.
- brand vacuum pump with high pumping speed and low noise.
- oil mist filter is equipped as standard to avoid the toxicity of oil mist to human body during vacuum pumping.
- pre freeze drying is carried out in situ, which reduces the cumbersome operation in the drying process and realizes the automation of the freeze drying process;
- silicone oil is used as circulating medium, with high temperature control accuracy, shelf temperature difference ≤ 1 ℃, and uniform drying effect;
- Shelf pre freezing temperature is adjustable, controllable, groping, pilot test and production process;
- Multiple sets of programs can be stored, with each program programmable to set the pre freezing and drying sections. The freeze-drying machine can modify program parameters during operation and record drying curves and data;
- 7-inch touch screen operation, PLC industrial controller, display drying curve and data change;
- square tray is not easy to deform, easy to operate and easy to clean;
- user level and password can be set for decentralized operation management;
- equipped with inflation valve, which can be filled with nitrogen or inert gas for storage after drying.
- Defrosting system: natural defrosting
- heating control system of board layer:
Thermal cycle protection, special heating materials, fuzzy PLD control algorithm.
The optimal control algorithm of freeze-drying curve can control the heating rate of samples in the stages of sublimation and analytical drying.
The industrial touch screen is adopted, with good man-machine interaction, simple and easy to understand, and simple operation can be carried out without instructions.
- Data recording system:
External storage (USB flash disk), the amount of data stored is related to the capacity of USB flash disk
PC database storage. The amount of data stored is related to the usable capacity of computer hard disk (optional).
Calibration function:
Temperature and vacuum can be calibrated to ensure the accuracy of measured values for long-term use.
Freeze drying curve query function (temperature and vacuum curve can be queried to facilitate process optimization and freeze drying effect verification).
Optional (extra charge):
1. Optional bottle hanging device, eggplant bottle or wide mouth bottle;
2. Optional imported brand vacuum pump to ensure more reliable operation;
3. The eutectic point test function can be selected to facilitate the exploration of the freeze-drying process of the sample;
4. Optional high-precision vacuum degree control, vacuum fluctuation value ≤± 0.3pa;
6. Remote real-time monitoring at PC end can be selected to realize computer remote control;
