Shorty, as long as you are actually filtering what is the part when the funnel is full with solvent, the fridge compressor will actually work much better as there is minimal airflow. (the solvent in the funnel works as seal here).
What you refer to is actually the drying out of the filter cake what does not belong to the process of filtering by definition.
Enough nitpicking, solutions:
Vacuum filter with the fridge compressor, for drying the filter cake attach an hairdryer and blow/press air through the filter. Those flexible aluminium hoses do a perfect job here, a bigger baloon cut open on both ends (use the cigar shaped ones) allows easy airtight sealing on filter and hose by using just a rubber band.
- minimized explosion risk
- possibilty to heat air for even faster drying
- hairdryer is smaller, cheaper and to use for evapourating enhancement
