Latest Patents

Among Andrew's latest patents is a process for the oxygen delignification of pulp mill rejects. This innovative technique separates rejects such as knots, shives, slivers, chops, and uncooked wood chips from a pulp slurry. By treating these materials to produce a bleachable grade pulp, Martin’s process achieves low external power requirements and eliminates the need for expensive dewatering machinery. The delignification occurs at temperatures ranging from 80 to 140 degrees Celsius for 5 to 120 minutes, ultimately yielding a high-quality pulp that can be utilized either independently or in combination with other pulp.

Another remarkable patent is the center flow screening apparatus. This pressurized screening device incorporates two pairs of concentric cylindrical screen plates, each equipped with its own rotary impeller mechanism. By sharing a common feed chamber and drive for the rotary impellers, this design enhances operational capacity while efficiently removing heavy and light impurities from feed streams.
