If this is a recurring problem you might consider assembling a 1.5" diameter triclamp pipe with an inline sight glass at one end.
You could fill the tube with your current sauce/crystals, apply low pressure and then wait for the crystals to fall to the bottom.
The sight glass obviously let’s you see the crystals. The smaller diameter and the longer length will make it easier to collect your sauce fraction if you modified a Mason jar lid like whats shown in the picture below. A water aspirator with a stainless 1/8" tube attached by a hose would be ideal to suck the sauce fraction out of the pipe and the modified mason jar lid would be ideal to return the sauce fraction back to a mason jar.
