KEK Centrifugal Sifter – Gravity
High volume screening & sifting for food,
pharma, and chemical industries
Screening and Deagglomeration
The KEK Centrifugal Sifter is recognized as the leading high-capacity sifting and screening solution for food, chemical and pharmaceutical industries globally. KEK Sifter classify the size of material by sifting and separating out material that isn’t to the required size. This screening process removes unwanted material and minimizes risk to the process from contaminants.

A Centrifugal Sifter is used to sift and screen high volumes of material, at high speed and with greater efficiency in comparison to other sifter used by material producers, such as Food producers, as well as Pharmaceuticals and Chemical manufacturers.
The process of Sifting material not only allows for size classification; separating material that isn’t of the required size, but also ensures a ‘screening process’ by removing unwanted material and de-risking powder handling.
Rotary Sifter is also a common name for this type of centrifugal processing machine, as can be a Flour Sifter or Powder Sifter. The sieving process of powders and granules takes place in gravity and in-line applications, while output with KEK varies from over 90 tons per hour, down to a few pounds.
