Application of freeze dryer in insulin freeze drying


     With the continuous development of lyophilizer technology, it is widely used in the fields of medicine, biological products, food, blood products and active substances. At present, the application of lyophilizers is still expanding. For example: in the application of insulin freeze drying.


 The lyophilization process of insulin includes the following steps:


1. Pretreatment of crystallization of insulin to be lyophilized;


2. Turn on the freeze dryer, adjust the temperature in the freeze-drying chamber to below -25 °C, and place the pretreated insulin crystals into the freeze dryer for rapid freezing.

;

3. Adjust the temperature in the freeze-drying chamber to -15 °C, keep the temperature of the freeze-drying chamber -15±2 °C, and pre-freeze the product 2 times.

Time;


4. Adjust the condenser temperature to -40 ± 2 ° C, then adjust the temperature of the freeze drying chamber to 0 ° C, the temperature per hour does not exceed 2 ° C, under vacuum conditions, and maintain f 2 hours;


5. Continue to adjust the temperature of the freeze drying chamber to 15 ° C, the temperature per hour does not exceed 7.5 ° C, maintain the temperature of the freeze drying chamber at about 15 ° C, and keep it for 2 hours under vacuum conditions;


6. Turn off the freeze-drying machine, adjust the freeze-drying indoor environment to normal pressure and normal temperature, and take out the insulin lyophilized product.
