Beijing Songyuan Huaxing Technology Development Co., Ltd. is Freeze Dryer/lyophilization equipment supplier/Manufacturer in China, which has 20+ years of industry experience. To reduce equipment energy consumption, branches and special maintenance stations are set up throughout the country.

Freeze Dryer China consists of refrigeration system, vacuum system, heating system and electrical instrumentation control system. The main components are drying ovens, condensers, refrigeration units, vacuum pumps, heating/cooling devices, etc. Its working principle is to freeze the items to be dried below the triple point temperature, and then vacuum the solid water (ice) in the product to directly sublimate into water vapor, remove from the items, and make the items dry. After the material is pre-treated, it is sent to the quick-freezing warehouse for freezing, then sent to the drying warehouse for sublimation and dehydration, and then packaged in the post-processing workshop.
Freeze Dryer China freeze-dried curve should be how to draw it?
The lyophilization curve can be obtained by recording the changes in shelf temperature and product temperature of the freeze dryer over time. The typical freeze-drying curve divides the temperature of the shelf into two phases. The shelf temperature is kept low during mass sublimation. According to the actual situation, it can generally be controlled between -10 and +10. In the second stage, the temperature of the shelf is appropriately adjusted according to the nature of the product. This method is applicable to products whose melting point is lower. If the performance of the product is not clear, the machine performance is poor or the work is not stable enough, this method is also more stable.
If the eutectic point of the product is high, the vacuum degree of the system can also be maintained well, and the cooling capacity of the condenser is sufficient, a certain heating rate can also be used to raise the shelf temperature to the maximum allowable temperature until the end of lyophilization. However, it is also necessary to ensure that the temperature of the product during sublimation does not exceed the eutectic point.
