Medicine And Health Care Product Freeze Dryer
Medicine And Health Care Product Freeze Dryer
The vial bottle is the main form of packaging for sterile powdered medicines, and it is used in large quantities.Why does the vial break when freeze-dried?
First, the reasons for equipment manufacturing
At present, there are still many shortcomings in domestic freeze dryers. Individual enterprises are still in the structure of imitation foreign freeze dryers, and they do not have the principle of design and manufacture. Due to the different technical qualities, different design structures and manufacturing processes, there is no uniform standard. Some manufacturers have poor flatness of the shelf, especially for large-area shelves. When the tampon is finished after lyophilization, the pressure distribution is uneven, causing individual bottles to be crushed.
Second, the quality of the vial itself
This is an important factor affecting the rate of freeze-drying. We know that the vials need to be ultrasonically cleaned and autoclaved to remove the heat source before filling. No matter which process, the vials are a test. The intensity of the ultrasonic wave during cleaning and the impact of water vapor have a certain influence on the glass, and the uneven distribution of the temperature of the tunnel oven is prone to sudden heat and quenching, which is a major damage to the poor quality of the vial. Perhaps the appearance of the bottle can not be seen with the naked eye, but it may produce tiny cracks, so that it is not enough to withstand the temperature changes during the subsequent freeze-drying process. The bottlenecks of different degrees in the domestically produced bottles have been severely affected, and even more than 10%, and the bottle breaking rate of the good zulin bottles in China is far from the imported vials.
