Abstract: A temperature transfer filter plate assembly for a filter press includes a temperature transfer filter plate in a filter plate assembly having a plate chamber for receiving heating or cooling fluid. A plurality of apertures extend through the filter plate to enable the flow of liquid therethrough. A filter frame includes a web or divider wall that receives temperature transfer filter plates on opposing sides thereof. The apertures of each temperature transfer filter plate open into respective collecting chambers defined by the inner wall of the temperature transfer filter plate and the divider wall. A flow path arrangement allows removal of the liquid from the collecting chambers in the temperature transfer filter plate assembly. The temperature transfer filter plates generally have inner and outer walls with a wavy or undulating configuration to form the plate chamber therebetween.

Abstract: A filter press (11) defined by a closable stack of filter plates defined by a first plurality of membrane filter plates (21) alternately disposed with a second plurality of heating-type filter plates (22). The membrane plates (21) have chamber-defining recesses on opposite sides thereof, with each recess (36) having a flexible membrane (39) associated therewith which can be pressurized from the rearward side so as to effect squeezing of the cake in the filtration chamber. Each heating plate (22) also has chamber-defining recesses (74) on opposite sides thereof, and the main center bottom wall (76) of each recess (74) has a metal heat transfer surface (77) associated therewith, the rear side of which is in intimate contact with a chamber or passage (79) which receives therein a high-temperature heat transfer fluid.
