Four-ring lyophilization experimental freeze dryer emergency fault treatment

The working principle of the four-ring lyophilization experimental type freeze dryer is to freeze the dried items to below the three-phase point temperature first, and then directly sublimate the solid water (ice) in the articles into water vapor under vacuum conditions, which is eliminated from the articles to dry
the items.
After the material is pre-treated, it is sent to the quick-freezing warehouse to freeze, and then sent to the drying bin for sublimation and dehydration, and then packed
in the post-treatment workshop.
The vacuum system establishes low pressure conditions for the sublimation drying chamber, the heating system provides the sublimation latent heat to the material, and the refrigeration system provides the required cooling capacity
to the cold trap and drying chamber.
Four-ring freeze-drying experimental freeze-dryer is the equipment for the production of lyophilized products, each customer hopes that their equipment can run stably for a long time, in fact, its good working conditions depend on the following three points: regular maintenance; Handling of emergency failures; Scientific inspection system and problem handling process
.
1.
Regular maintenance
.
Any equipment needs to be regularly maintained, which is a necessary condition to ensure the normal operation of the equipment, and a reasonable maintenance plan and charter can also reduce the failure rate of the equipment, so that the equipment is put into production and operation in good working conditions, and the necessary maintenance will be carried out after the equipment is stopped
.
2.
Emergency fault handling
.
Vacuum freeze dryers, like other equipment, some failures may really not be completely avoided, so the treatment process of emergency failures is very important
.
For example, in the face of unexpected failures such as power outages and failure of key components of equipment, users with handling plans and usually skilled drills can reduce the losses caused by emergency failures, while those users without emergency plans often suffer serious losses, and even lead to the scrapping
of the entire batch of drugs.
3.
Reasonable inspection system and problem handling process
.
In fact, most of the faults of the lyophilizer can be found and solved
in advance during the patrol inspection.
The scientific daily, weekly, monthly, quarterly and annual inspection systems can effectively find potential faults and risks, and with the conventional fault handling process, failures can be largely avoided
