Introduction

Takayuki Isogai is a notable inventor based in Fukuoka, Japan. He has made significant contributions to the fields of centrifugal technology and chemical processing, holding a total of 2 patents. His innovative designs address critical challenges in industrial applications.

Latest Patents

One of Isogai's latest patents is a centrifugal machine, specifically a screen bowl type centrifugal separator. This invention effectively eliminates productivity issues caused by clogging with crystals in the screen part. It also minimizes the leakage of the object being treated. The design includes a cleaning liquid receiving part within the hub of the screw conveyor, which is responsible for receiving cleaning liquid for the cleaning nozzle. Additionally, it features a residual layer crystal cleaning liquid receiving part that independently manages the cleaning liquid for the residual layer object in the screen part. The cleaning liquid is jetted directly toward the residual layer object from the outer circumferential edge of the flight, ensuring efficient cleaning.

Another significant patent is a process for preparing an aqueous slurry of terephthalic acid. This process involves oxidizing p-xylene with molecular oxygen in a liquid phase using an acetic acid solvent and a catalyst. The result is an acetic acid slurry of terephthalic acid, from which crystals are separated and washed with p-xylene or an acetic acid ester before mixing with water.
