The effect of temperature was examined on the moisture content and physical characteristics of lactic, sulphuric and rennet casein curd, after dewatering in pilot-scale versions of a roller press, screw press and decanter centrifuge. Temperatures ranged from 20 to 38 degrees C for the screw press and 20 to 50 degrees C for the roller press curd centrifuge and were controlled by steam injection in the feed pipes to the machines.
