Latest Patents

One of his latest patents is titled "Arrangement for mixing flows in papermaking process." This invention relates to a method and a mixer designed for mixing flows within the papermaking process. In this invention, a first flow is conveyed through a tube, where turbulence is generated by form parts located on the inner periphery of the tube. The mixing zone of the mixer features feed openings on the inner periphery of the tube, allowing a second flow from a feed channel outside the tube to be introduced into the first flow. This results in effective mixing due to the turbulence created by the form parts. A preferred embodiment of this invention includes at least one form part that comprises a feed opening.

Another significant patent by Juhani Sams is the "Method and device for feeding chemicals into a fibre suspension." This invention is particularly relevant in the short circulation of a paper machine. It describes a process where a chemicals flow is introduced into a fibre suspension flow at a pipe expansion. This expansion consists of a first pipe and a second pipe with a larger diameter than the first. These pipes are interconnected by an expansion step that is perpendicular to the flow direction. The chemicals flow can be mixed with the fibre suspension either in the second pipe, in an ideal mixing zone after the expansion step, or in the first pipe, close to the expansion step, ensuring that the chemicals have minimal reaction time before entering the expansion step.
