Many freeze dryers have an automatic control system and also have manual control functions, but there are big differences between the manufacturers in the way of automatic control, and the user must figure out. The automatic control of the so-called freeze dryer should include two parts. First, the equipment of the freeze dryer automatically stops at the specified time according to the freeze-drying process requirements. Second, the temperature of the freeze-drying tank layer is automatically tracked according to the freeze-drying curve requirements. The entire freeze-drying process does not require manual operations, although manual intervention can be performed if desired. However, the automatic control of some freeze dryers is incomplete, only the freeze-drying curve can be automatically tracked, and the rest must be manually operated. The automatic control of some freeze dryers can only be completed after lyophilization. The tampon in the tank after the lyophilization is completed, the defrosting of the condenser and the steam sterilization cannot be carried out automatically. Manual operation is required, especially the steam disinfection part, because many valves are involved. Control, manual operation is more troublesome, should choose the lyophilizer of the automatic disinfection program. Some lyophilizers use automatic microcomputers for convenient operation and programming. The displayed language is a freeze-drying language. It also has a fluorescent screen, a printer and a floppy disk. It can store dozens of frozen programs at the same time. Each program content can be displayed. The entire program content can be printed by the printer. The automatic control of the lyophilizer uses a meter, which is troublesome to operate and program, and has less lyophilization procedures that can be stored. The recording instrument is also an important instrument for the freezer. It can record the entire freeze-dried actual process in a vacuum, so that it can be stored in the future. Most of the recording instruments use a multi-point recorder, which can be used for both point and direct operation. Text records, as well as digital display systems. The Pilot series of freeze dryers from Beijing Bo Medical Kang adopts an advanced closed loop control automatic control system. The user can adjust the Automation system through the touch screen and PLC (programmable controller). At the same time, the Pilot series freeze dryers have a variety of different models, users can choose according to their specific circumstances.
