The 23-liter Valley Beater (Valley Beater) is an internationally standardized piece of equipment used in paper-making laboratories. It is an essential device for studying the pulp and paper-making process. The machine employs the mechanical force generated between a flying knife roller and a bottom knife to cut, crush, knead, split, swell, and refine various fiber pulps. This process also causes displacement and deformation of the fiber cell walls and ruptures the outer layers of the primary and secondary walls. By adjusting the pressure on the bottom knife and the beating time, it is possible to achieve pulp with different degrees of beating. The Valley Beater is widely used in beating tests of various plant fibers, synthetic fibers, carbon fibers, and glass fibers. It is an indispensable piece of experimental equipment for paper production testing, quality control, process formulation, and teaching and scientific research tests.
