  • Method of and device for continuously swelling starchy raw materials
    Patent number: 4936919
    Abstract: The method allows in particular the continuous swelling of granular, starchy raw materials subject to mechanically increased hydraulic pressure. Extraction is very effective because the steep and the raw material flow in opposite directions. The opposed currents are produced because the swelling section is upright, so that gravity forces the heavier raw material down through the rising steep.
