Title: Hisao Itoh: Innovator in Aerobic Culture and Alkali Metal Polyphosphates
Introduction
Hisao Itoh is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the fields of aerobic culture and chemical processes, holding a total of 3 patents. His work has enhanced productivity in fermentation processes and the production of alkali metal polyphosphates.
Latest Patents
His latest patents include a culture device for aerobic culture and a method of controlling foams by defoaming. This innovative device features a foam detecting sensor and an ultrasonic oscillation horn mounted on a vertical pipeline between a culture tank and a liquid-vapor separating device. When overflowed foams are subjected to ultrasonic irradiation, they burst and lose volume. The burst foams exhibit a higher apparent density compared to the foams before irradiation. Consequently, the concurrent use of ultrasonic oscillation devices and the liquid-vapor separating device, such as a cyclone, leads to enhanced liquid-vapor separation efficiency and higher productivity by fermentation.
Another significant patent is the process for producing alkali metal polyphosphates. This process involves heating a solution containing a solvent, alkali metal ions, phosphate ions, and 3 to 50% by weight of organic matter. The solution must contain a total of 5 to 65% by weight of the alkali metal ions and phosphate ions, with a ratio of M/P ranging from 1.0 to 3.0. The heating occurs at a temperature of 800°C to 1200°C in the presence of excess air, optionally after the solution is at least partially dried to solid, resulting in the production of alkali metal polyphosphate.
