Latest Patents

Alfred Lang holds a patent for a "Twin conical refiner with dual ribbon feeders." This invention provides an apparatus and method for the mechanical refining of high consistency lignocellulosic feed material in a frustroconical refining zone. The design facilitates the backflow of steam generated in the refining zone through the upstream feed zone, allowing the feed material to enter the refining zone without blockage or flow interruption. The hybrid feed/grinding zone acts on wood chips with high refining intensity at low power, effectively reducing the size of the material and conveying it into the refining zone against the backflowing steam.

Career Highlights

Alfred Lang is associated with Andritz Sprout-Bauer, Inc., where he applies his expertise in mechanical refining technology. His work has been instrumental in advancing the efficiency and effectiveness of refining processes in the industry.
