Martin, That's the standard practice done here, or at least heating the fats and oils to 140*F and let to settle. But it's the bottom 10% of the meats and chips and fines mixed with oil that needs to have as much oil pressed out of it as possible.
Up to this point I was contemplating a 25 gallon capacity metal screen in cylindrical form, reinforced with steel, running both horizontal and vertical, throwing a thick bag filter inside the sleeve, filling with the "slime" left over from every couple hundred gallons of oil, placing a circular steel plate on top of the bag and applying slow but constant pressure using a screw or hydraulic press. It could cost as much to fabricate as might a small refurbished oilseed press, presuming that an oilseed press could do the job. At the moment an oilseed press is not on my shopping list.
