Title: The Innovations of Shoji Tsujita
Introduction
Shoji Tsujita is a notable inventor based in Itami, Japan. He has made significant contributions to the field of biomass processing, particularly in the production of saccharified solutions. With a total of six patents to his name, Tsujita's work focuses on enhancing the efficiency of enzymatic methods using cellulose-type biomass as raw material.
Latest Patents
One of Tsujita's latest patents is a method for producing a saccharified solution by enzymatic means. This innovative approach allows for a high concentration of solids in a reactor during the initial stages of hydrolyzing cellulose contained in biomass. The method involves mixing an aqueous solution with pulverized biomass, which is gradually added while the reactor content is stirred. The final solid concentration is maintained between 15 to 30% by mass, and the reactor features a conical or mirror plate bottom with multiple stirring fans to ensure effective mixing.
Another significant patent involves a method and apparatus for producing a saccharified solution using biomass as raw material in a continuous reactor. This method hydrothermally treats cellulosic biomass slurry in either a supercritical or subcritical state. It effectively reduces the risk of clogging in pressure reducing valves during the flash evaporation of high-temperature and high-pressure slurry. The continuous reactor design allows for intense stirring at the front and gentle mixing at the rear, ensuring uniformity in the slurry.
