Latest Patents

John Edward Crook holds a patent for a "Component spool and shell pressure vessel with hydraulic fluid actuated." This invention is a process and apparatus designed for expanding tobacco at rapid throughput rates. The apparatus features a spool and shell assembly, where the spool can move in and out of the shell between various positions, including loading, impregnating, and unloading. In the impregnating position, sealing assemblies effectively seal the radial clearance between the spool and shell, creating a pressure vessel for tobacco impregnation. The sealing assemblies consist of at least one elastically deformable sealing ring and an annularly shaped axial pressure applying member, which applies axial pressure to the sealing ring. This member receives fluid pressure from hydraulic fluid and additional pressure from the expansion agent used to expand the tobacco.
