Abstract
A method for dewatering slurry product streams of a corn wet milling process is disclosed. The dewatering process uses an automatic pressure filter to perform the dewatering. The filter is operated at 4 to 20 bars pressure for about 5 to 25 minutes. Such filter is shown to have an improved efficiency over conventional mechanical filtering devices.
