The pilot-scale vacuum freeze dryer is not only suitable for the exploration and optimization of the freeze-drying process to prepare for large-scale production, but also for small batch production. It is an ideal equipment for enterprises and scientific research institutes to conduct pilot and small batch production. It is generally divided into two types: one is a heating system that uses electric heating as the heating medium. One is a system that uses silicone oil as the heating medium. In terms of appearance, there are square cabins and round cabins. Taking the shelter freeze dryer as an example, electric heating and silicone oil heating are discussed below.

The shelf refrigeration of the electric heating freeze dryer is directly from the evaporating end of the compressor; the refrigeration is rapid and the temperature is low. In the process of heating and heating, due to the rapid cooling, the conflict between cooling and heating is caused, the temperature control is easy to be uneven, and the temperature error is relatively large. But its advantage is that the price is more competitive. For materials that are generally sensitive to temperature, we recommend using a freeze dryer heated by silicone oil. Because its cooling and heating are very reliable, the temperature can be controlled within 1 °C, and it will not cause damage to the material.

The performance characteristics of the pilot vacuum freeze dryer:

1. Cascade refrigeration technology can shorten freeze-drying time, ensure imported brands, reduce noise, large refrigeration capacity, large water capture capacity, high quality and good performance;

2. Touch screen LCD display, drying process curve and data display, new PID control, convenient for users to learn more information according to data changes;

3. Built-in observation window, the freeze-drying process is intuitive. On-site pre-freezing is used to realize full automation from vacuum to drying, reducing tedious operations in the drying process;

4. The freeze-drying room is made of 304 stainless steel, which is corrosion-resistant, easy to clean and durable;

5. Silicone oil freezing medium, the error is less than or equal to 1°C, and the drying effect is uniform;

6. Equipped with a charging valve, which can be filled with dry inert gas; imported refrigeration compressor, reliable operation and long service life;

7. Excellent square shelves are not easy to deform, easy to operate and easy to clean;

8. The drying room adopts high light transmission, colorless and transparent plexiglass door, which can clearly observe the changing process of materials during operation;

9. Optional temperature recorder. The temperature recording point is adjustable, real-time monitoring, to increase the protection for your experience accumulation;

10. The pilot-scale freeze dryer can be equipped with a eutectic point test device; an automatic plugging device (capped freeze dryer) can be selected.

Pilot-scale vacuum freeze dryers are widely used in medical, pharmaceutical, biological research, chemical and food fields. The freeze-dried articles are easy to be stored for a long time, and can be restored to the state before freeze-drying and maintain the original biochemical properties after rehydration. We support order and wholesale of freeze dryers. Welcome customers to consult online or visit our factory.
