Processing time comparison between perfusion and conventional methods.

Processing Time	Perfusion (perf.)	Conventional Methods (conv.)	Time Ratio (Tperf./Tconv.)
Solvent Removal	15 min	48 h	1/192
Salt particle Removal	4 h	48 h	1/12
Residual water removal	10 min	10 h	1/60

By perfusing with ethanol, water, and dry air sequentially, the solvent, salt, and residual water were quickly removed. Our perfusion-based approach has a processing time that is more than 20 fold faster than conventional methods.
