Weight of freeze-dried balls

The weight of the freeze-dried ball is 700 kg. Freeze-dried beads have the advantages of convenient transfer, rapid dissolution, rapid transportation and storage at room temperature. At the same time, they are small in size, light in weight, easy to be damaged by static electricity and fast in moisture absorption. Therefore, in the current process of freeze-dried beads, the sub-packaging of freeze-dried beads is very challenging.

Characteristics of freeze-dried pills

The rapid collection of freeze-dried microspheres requires rapid and safe collection from liquid nitrogen containers and post-treatment. Some reagents can't stay in the low temperature environment of liquid nitrogen degree 194℃ for too long, so they need to be taken out of liquid nitrogen safely and efficiently and stored in dry ice or other low temperature environment for dozens of minutes or 1 hour.

Generally, in the early development and small batch production of freeze-dried pellets, manual sub-packaging can be carried out in isolators or drying workshops. This packing method is very simple and convenient, but it also has some shortcomings, such as the need for people to operate outside the isolator through the glove box, which is difficult to operate and consumes labor costs.
