The sudden expansion of the chips in the impregnator enables the chips to instantly soak up the impregnation chemicals provided to the impregnator.
The sudden expansion allows the chemicals to penetrate the chips homogeneously. The fully impregnated chips are elevated above the level of the liquid by twin-screws.
An impregnator is placed as a mixer between the plug-screw feeder and the screw conveyor to a reaction bin.
