Product Description:
Vacuum freeze drying technology, referred to as freeze drying, is also known as sublimation drying. It is used in the pharmaceutical, biological, chemical and food industries.
Main features: Pre-freeze drying is carried out in situ, which reduces the cumbersome operation of the drying process and realizes the automation of the freeze-drying process.
Silicone oil is used as a circulating medium, with high temperature control accuracy, 1 temperature difference of the shelf, and uniform drying effect.
The temperature of the shelf can be adjusted, controllable, explored, pilot and production process.
Software operating system with independent intellectual property rights.
7-inch true color touch LCD screen, real-time recording and display of cold trap temperature, sample temperature, separator temperature, vacuum degree.
The data can be exported via USB, and the upper computer software control can be selected, which supports computer browsing and printing.
It can store 32 programs, each program can be set with 40 segments, the program parameters can be modified during operation, and the final drying curve can be recorded.
Because the drying chamber and the cold trap are split structure, the water capture capacity is strong and the drying time is short.
The temperature of the cold trap can be preset, and the vacuum pump will be started when the temperature is lower than the preset, which effectively protects the vacuum pump.
The sample pre-freezing temperature can be set, and the linear cooling or program cooling can be selected.
The square tray is not easy to deform, easy to operate, and easy to clean.
It is equipped with a gas filling valve to fill dry inert gas.
The drying chamber adopts a high light transmittance colorless transparent plexiglass door, which can clearly observe the change process of materials during operation.
