The function of the freeze dryer also reflects the technical level of the production plant. In addition to accurate control and temperature operation, the control functions of the freeze dryer, such as in-situ pre freezing, slope temperature control, vacuum drying and program drying mode selection, remote operation and monitoring function, process setting, data storage, authority management and other functions, are the embodiment of the strength of FZG freeze dryer equipment processing plant So that enterprises that need freeze-drying machine equipment can better choose freeze-drying machine equipment manufacturers and use advanced, stable, energy-saving and efficient freeze-drying machine equipment.

The pilot freeze dryer adopts silicone oil medium for heat conduction to ensure that the temperature of each shelf and each point of the shelf is consistent, and the temperature control accuracy is high. High transparent plexiglass door panel is adopted to conveniently observe the freeze-drying process of articles. The electric control system has powerful functions. It can not only set the freeze-drying process, but also choose the PLC system to realize the functions of eutectic point test, remote control and so on.

Types of freeze dryer

From the perspective of freeze-drying application, it is mainly divided into food freeze-drying machine and pharmaceutical freeze-drying machine. Because the production requirements of drugs are higher than those of food, the manufacturing technical indexes of pharmaceutical freeze-drying machine are also stricter than those of food freeze-drying machine, whether it is equipment material, parts, performance parameters, box dead corner requirements, etc.

In terms of freeze-drying output, it is mainly divided into experimental freeze-drying machine, pilot freeze-drying machine and large freeze-drying machine. Laboratory freeze dryer is mainly used in universities, universities, scientific research and other laboratory places. It is characterized by transparent glass cover as drying room, small treatment and single function.

The design and manufacturing process of the lyophilizer and the selection of parts are directly related to the quality, reliability and service life of the lyophilizer. In order to make the cooling and heating temperature of the plate layer uniform, at present, most freeze-drying machine manufacturers use hollow sandwich plate layer with spacer inside, which is circulated in the plate layer by the temperature transfer intermediate fluid. The old or backward manufacturing method is to make holes on the upper and lower two or one of the plates of the plate layer, weld the metal plate with the spacer by plug welding, and then machine it.
