An apparatus for mixing and heating a foodstuff of particulate material with a liquid comprising:
- (a) a means for introducing particulate material;
- (b) an inclined barrel extending upwardly from and in communication with the means for introducing the particulate material, said barrel terminating at an upper discharge end;
- (c) a conveyor screw rotatably mounted in said barrel to convey particulate material upwardly through the barrel towards the discharge end, said conveyor screw having a plurality of screw flights including a first and last screw flight (12');
- (d) a mixing zone within said barrel formed by the barrel projecting beyond the last screw flight (12'), said zone being defined by the walls of the barrel, the last screw flight (12') and the discharge end of the barrel;
- (e) at least two opposing liquid inlet openings in said barrel positioned in the mixing zone;
- and
- (f) a means for introducting streams of heated liquid into said liquid inlet openings such that the liquid mixes with and heats the particulate material in the mixing zone and a premix of particulate material/liquid is discharged from the discharge end of the barrel.
