The Intensive Screw Dampener, made of stainless steel, is used to add water evenly to clean cereals before resting phase, so as to prepare them for the subsequent milling process with the correct percentage of moisture. The cereal is wetted by the spray nozzle placed on the lid and mixed by the coil mounted on the initial part of the rotor. The pallets fixed in the remaining length of the rotor complete the mixing by dragging, with their motion, the product towards the drain. The possibility of varying the inclination of the case allows the mixing time to be changed
