pharmaceutical productionFreeze Dryer，Also known as pharmaceutical vacuum freeze dryer, it is a device that uses the principle of sublimation to crystallize water containing thermosensitive substances through low-temperature freezing, and then removes water directly without liquid sublimation in a vacuum state.Design of Freeze Drying Machineusesafety、multipurposesexuallyReliableSex andservice lifeLong forfoundation.The freeze-drying machine also fully ensures the safety of users and the environment. The design of the freeze-drying machine is based on mature technology and adoptsBiology andHigh quality materials and components widely accepted in the pharmaceutical industry. Simultaneously adopting high-tech manufacturing processes, the equipment fully complies with cGMP standards.The pharmaceutical freeze-drying machine equipment produced ranges from 0.5 square meters to 50 square meters in freeze-drying area, meeting the needs of most users.

Manufacturing Technology of Pharmaceutical Freeze Drying Machine：

1Box manufacturing:
1）Box material AISI 304 or AISI316L，Rounded corners inside the boxhandleReduce blind spots；

2）boxAll internal welds are processed to smooth out the surrounding materials.

2Partition manufacturing:

1）a partitionDuring manufacturing, the material is uniformly heated to avoid stress generated between independent welds,ensuredThe flatness of the shelf is good.

2）The use of hollow partitions on the shelf increases the heat exchange area between the shelf and the silicone oil,letThe temperature uniformity of the shelf is faster；

3Cold trapmanufacture：

1）The material is AISI 304/316stainless steel. Mechanical polishing of the interior of the cold trap container to<0.75 μ mRa;

2）The top of the cold trap is equipped with a nozzle for spraying hot water or steam for defrosting in the final stage of the process

4、Refrigeration system manufacturing:
1) Adopting ultra-low temperature refrigeration technology, with strong refrigeration capacity and fast cooling speed;

2）Adopting a two-stage semi enclosed screw compressorThe unit accessories are made of imported brands to ensure equipment quality；

5Vacuum system manufacturing:

1) Choose vacuum pumps from brands such as BAISI, Edward, and Leybold to ensure high vacuum levels;

2) Equipped with anti backflow function, equipped with a single acting butterfly valve that automatically closes after gas and power outages to prevent backflow;

control systemmanufacture:

1）PLC system computer operation, controlAll functions of freeze-drying machine，Complete the operation of the entire production system，System stability and security；

2）Capable of process setting, temperature and vacuum control adjustment, and endpoint judgment;

3）Having datastorage、Data traceability, freeze-drying curve query, and permission management functions;

4）Various system protection functions, with remote operation and monitoring capabilities.
