Zusammenfassung:	A method for continuously filtering a liquid slurry, such as an oil sand and solvent slurry, in a horizontal pan filtering device is provided. In particular, separate filtrate receivers are built under the wet and the dry sectors of a pan filter to take advantage of the liquid seal at the wet sectors so that the solids in the slurry can be compressed by having a higher vacuum under the wet sectors.
