OUR STRENGTHS AND FEATURES CHUO KAKOHKI’s Strengths and Features

Japan's Pioneer and #1
in Vibrating Mills & Dryers.

While CHUO KAKOHKI started with distillation technology, it has consistently pioneered new technologies to meet the demands of changing times and evolving customer needs. This eventually led to the development of Japan's first vibrating mill in 1961. The addition of vibrating parts inherently made machines prone to breakdown. While other companies abandoned their efforts for various reasons, CHUO KAKOHKI persisted through trial and error, successfully manufacturing robust vibrating mills that endured even in large sizes. Since then, CHUO KAKOHKI has led the industry as a pioneer of mills and dryers utilizing vibration technology. This achievement boasts an over 95% share of the Japanese market (*). The exclusive know-how, cultivated through continuous technological innovation, is truly a culmination of our engineers' passion. We will continue to challenge new possibilities.

*According to our research in 2023, for the domestic market of vibrating dryers and vibrating mills.

Fully custom‑made from the design stage.
We respond to a wide range of customer needs.

With proposal capabilities backed by a wealth of experience and a proven track record, we develop custom-made products that meet our customers’ requirements. We provide a one-stop service from design, manufacturing, and testing to on-site installation (including wiring and piping), allowing us to flexibly respond to diverse requests. We are particularly skilled in the design and manufacture of equipment for raw material production that requires high precision, such as for electronic components and fine chemicals where contamination by foreign matter is unacceptable.

    Collaboration with the Industrial Technology Center of the Aichi Center for Industry and Science Technology, which is advancing R&D on cellulose nanofibers (CNF).

    CNF is expected to serve as an alternative material for a wide range of applications, and it was found that increasing the Mohs hardness of the dried particles from 2 to 4 makes them usable as a substitute for industrial abrasives (scrub agents).

    As a result of drying CNF using CHUO KAKOHKI's vibration dryer, the target Mohs hardness of 4 was achieved, contributing to the R&D effort.

    In recognition of this achievement, CHUO KAKOHKI received the 2023 "Technology Award" from the Society of Cellulose Science and Technology, Japan.
