Abstract:
A mixing system, comprising:a vessel configured to supply a liquid; a device configured to supply a number of wood pieces for mixing with the liquid; an elongate enclosure having a first end opposing a second end and defining a chamber in fluid communication with said vessel to receive the liquid, said chamber having an inlet and an outlet, said inlet being closer to said first end than said outlet, said chamber being configured to receive the pieces from said device through said inlet and to discharge the pieces through said outlet; a first motor-driven mixing auger positioned in said chamber and being configured to rotate about a rotational axis to intermix the liquid and the pieces, said first auger including: a first helical flight between said inlet and said outlet configured to convey the pieces in said chamber from said inlet to said outlet when rotated, said first flight turning about said rotational axis at least three revolutions between said inlet and said outlet; and a second helical flight between said first flight and said second end, said second flight having a length along the rotational axis shorter than said first flight, said second flight turning about said rotational axis at least 180 degrees and being at least partially positioned over said outlet, said second flight having a rotational orientation opposite the first flight.
