The necessity of medical vacuum freeze dryer cleaning work

2019-06-03
The Freeze Dryer/lyophilizer consists of a refrigeration system, a vacuum system, a heating system, and an electrical instrument control system. The main components are drying ovens, condensers, refrigeration units, vacuum pumps, heating/cooling devices, etc. The working principle of the Freeze Dryer is to freeze the dried articles to below the triple point temperature, and then directly sublimate the solid water (ice) in the article into water vapor under vacuum conditions, and remove the articles from the articles to make the articles dry. After the material is pre-treated, it is sent to the quick-freezing bin for freezing, and then sent to the drying bin for sublimation dehydration, and then packaged in the post-treatment workshop. The vacuum system establishes a low pressure condition for the sublimation drying chamber, the heating system provides sublimation latent heat to the material, and the refrigeration system provides the required cooling capacity to the cold trap and the drying chamber. The Vacuum Freeze Dryer adopts high-efficiency radiant heating to uniformly heat the material; it adopts high-efficiency water trap and can realize rapid defrosting; adopts high-efficiency vacuum unit and can realize oil-water separation; adopts parallel centralized refrigeration system and multi-channel on-demand cooling. The working condition is stable and energy-saving; the artificial intelligence control is adopted, the control precision is high, and the operation is convenient.
The quality requirements for freeze-dried products are: constant biological activity, uniform appearance and color, full shape, firm structure, fast dissolution rate and low residual moisture. To obtain high quality products, a comprehensive understanding of the theory and process of lyophilization should be obtained. The freeze-drying process of the Vacuum Lyophilizer

includes three stages of pre-freezing, sublimation and re-freezing. Reasonable and effective shortening of the freeze-drying cycle has obvious economic value in industrial production.

Freeze dryers are widely used and frequently used. Therefore, the normal use of vacuum freeze dryers is very important for enterprises. We all know that cars need regular maintenance after a certain distance. For other mechanical equipment, including vacuum freeze dryers, it is necessary to clean the vacuum freeze dryer.
The long-term work of the vacuum freeze dryer will bring the wear and dust and other impurities to the accessories, so let's take a look at the hazards of the vacuum freeze dryer:
When the evaporator of the vacuum freeze dryer indoor unit and the condenser of the outdoor unit are covered with dust, it will affect the emission of cold air and heat, which will cause the vacuum freeze dryer to reduce the cooling or heating effect, which is time consuming and expensive; when vacuum freeze drying When the machine is turned on, the bacteria in the vacuum freeze dryer will be directly blown into the indoor air, causing direct damage to the human body. After the vacuum freeze dryer was stopped in the summer, the Medical Vacuum Freeze Dryer was neglected, so a large amount of dust, mites, pollen, scorpions and molds adsorbed on the vacuum freeze dryer began to multiply. When the vacuum freeze dryer was used again in the second year, these bacteria, viruses, molds and dust were blown out by the dryer, often causing large-scale respiratory infections and allergic dermatitis.
Vacuum freeze dryer cleaning method:
Vacuum freeze dryers are generally cleaned and maintained before use in summer or after use in autumn. To completely kill the bacteria in the vacuum freeze dryer, it is best to have the professional technician clean the vacuum cleaning machine with a special cleaning solution.
Repair tips:
The cleaning of the vacuum freeze dryer directly affects the health of people, the so-called dryer disease, and the cause is also related to the cleaning of the vacuum freeze dryer.
