I am processing a slurry of reacted Lactic Acid, Ca and Mg. Once solubilized and at a temperature of 190 degrees F, we want to run it through a filter to get rid of any "non solubilized" material and then to a holding tank to be spray dried. The solids content is 40% and we have been using a bag/sock filter at 5 micron and then again at 50 micron. Problem is the slurry goes solid on the surface of the filter and backs up the system, then it cools down and all the liquid goes solid. Any suggestions?
