AI Technical Summary

Technical Problem

In existing freeze-dried powder screening devices, the exposed top of the screen makes it easy for the freeze-dried powder to leak out, resulting in waste.

Method used

The structure uses a cloth cover connected to a magnetic block. The top of the cloth cover rests on the limiting frame, and the bottom is attached to the iron clamping frame by the magnetic block to form a barrier to prevent powder leakage. At the same time, a funnel is set to collect the powder, and the motor drives the screen to rotate for easy cleaning. An electric linear guide rail drives the screen to shake, improving screening efficiency.

Benefits of technology

It effectively prevents freeze-dried powder from leaking out during the sieving process, reduces waste, simplifies the cleaning process, and improves sieving efficiency.
