With a total of four patents to his name, Kawashima's work has garnered attention for its innovative approaches and practical applications.

Latest Patents

One of Kawashima's latest patents involves a crystalline mixture solid containing maltitol. This invention features a crushed and relatively tight crystal structure observable at 1,000 magnifications by a scanning electron microscope. The crystalline mixture has an apparent specific gravity ranging from 0.650 to 0.750 and an oil absorptivity of 7.0% to 17% for powdered crystalline mixtures with particle sizes from 50 mesh to 20 mesh. The process for creating this mixture involves continuously supplying an aqueous solution of maltitol to an extruder equipped with elongated cooling and kneading zones, where it is cooled and kneaded in the presence of seed crystals to form a maltitol magma, which is then extruded from a nozzle.
