How to choose freeze dryer automatic control system

Many freeze dryers are equipped with automatic control systems and manual control functions. The so-called automatic control of freeze dryers should include two parts. One is that the various equipment of the freeze dryer automatically stops and starts at the specified time according to the freeze drying process requirements, and the other is that the temperature of the freeze drying box plate layer automatically tracks the freeze drying curve requirements. The entire freeze drying process does not require manual operation, of course, manual intervention is also possible if necessary.

However, the automatic control of some vacuum freeze dryer is incomplete and can only automatically track the freeze drying curve, and the rest needs manual operation. The automatic control of some freeze dryers can only reach the end of freeze drying. After the freeze drying, the box plug pressing, condenser defrosting and steam sterilization cannot be performed automatically and need manual operation, especially the steam sterilization part, because it involves many valve controls, manual operation is more troublesome, so a freeze dryer with automatic sterilization program is better.

Some freeze drying machines use a dedicated microcomputer for automatic control, which is easy to operate and program. It also has a fluorescent screen, printer and floppy disk, and can store dozens of freeze programs at the same time. Each program content can be displayed, and the entire program content can be printed out by the printer. Users should choose it according to specific circumstances.
