What do you encounter when the traditional drug freeze dryer enters and exits the material?

The traditional medicine freeze-drying machine is mainly as follows: after the completion of the semi-plug filling, under the protection of the A-level laminar flow, the manual loading is carried out, and the tray is transferred to the laminar flow vehicle, and then passed through the artificial The method pushes the laminar flow car to the front of the drug freeze-drying machine, and moves the plates in the car to the laminate of the drug freeze-drying machine one by one. The content of the lathe is the feeding mode, the discharging mode and the feeding mode. On the contrary, the Xiaoyuan freeze dryer will not be elaborated in detail.
Although this method can realize the operation and transshipment of products without safety sealing under laminar flow protection, it also has many problems, which are mainly manifested in the following two aspects:
First, in the process of operation or transportation, more operators are required, and the fluidity is also higher, and the probability of cross-contamination is large, and it is difficult to meet the dynamic criteria of the B-level region. When the laminar flow car is pushed to the B-class area, it will absorb a large amount of Class B clean air flow, which will easily affect and interfere with the B-level laminar flow.
Second, in the case of manual transfer, workers in different processes directly enter the Class A area, which also makes the area susceptible to contamination. The manual method of transferring the in and out of the material will affect the quality of some drugs, which may cause changes in the composition of the drug, and even worse. At the same time, the probability of contact between people and drugs is increased, and when people are exposed to sensitive drugs, it is easy to cause harm to the human body. In addition, the labor intensity of its work is large, so that its work efficiency is not improved.
