Centrifugal Sifter | high volume screening & sifting

Centrifugal Sifter | KEK Range for Material Processors

A Centrifugal Sifter is used to sift and screen high volumes of material, at high speed and with greater efficiency in comparison to other sifters 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 Sifters is also a common name for this type of centrifugal processing machine, as can be a Flour Sifter or Powder. The sieving process of powders and granules takes place in gravity and in-line applications, while output with KEK varies from over 90 tonnes per hour, down to a few kilograms.

DThe Unprecedented Benefits of KEK Sifters

Kemutec’s KEK Centrifugal Sifters provide the ideal sifting and screening solution for dry powder and other bulk solids. A specialised ‘Cantilever’ design offers users unprecedented, high standards in hygiene. This is achieved through the machine’s easy access and rapid screen change functionality, averaging at just 30 seconds.

Through extensive experience, Kemutec were the FIRST designer of powder processing equipment to engineer the ‘Cantilever’ feature.

Designed to help allow tool free maintenance, this feature results in optimised uptime and output. In addition to this, KEK Sifters are very easy to operate, making the sifting and screening process simple for the operator.

To sift a variety of materials, KEK Screens vary in size and construction. The Mesh Screen is ‘hand-made’ for high performance, making it renowned for supreme quality as well as durability.

  • Hygienic and efficient processing
  • Cleaning is easy and quick
  • Replacing the screen is simple
  • Paddle and scroll are easy to remove
    • NEW paddle assembly design to provide an even more advanced hygienic view
  • Easily inspect material through a machine panel

Typically used in food processing, as well as powder processing industries, the need for a hygienic design is paramount. This therefore makes KEK with its unique ‘Cantilever’ design, the best solution.

KEK Screen Options

The range is available with various DURABLE screening media options, to suit the specific application needs. These include:

Nylon Mesh

The most popular and versatile screening media. It provides high throughput rates and a wide range of mesh sizes down to 30µ.

Steel Mesh

Offers a wide size range and beneficial where applications require metal-detectable screen media.

Wedge Wire

A heavy-duty “slotted” type metal screen for abrasive check-sieving applications.

Perforated Plate

A heavy duty metal screen for high capacity check-sieving and abrasive materials.

Special Polymers

It is similar to Nylon Screens but uses special polymers, that can be resistant to high temperatures, corrosive products and static electricity.

In addition to these, KEK Sifters can be supplied with internal screen protectors and trash traps.

What KEK Sieves Can be Used For

KEK Centrifugal Sifters are ideal for the Sifting of Powders and Granules in gravity and inline installations with typical applications including:

Policing  Check sieving and removal of foreign contaminants

Scalping  Check sieving and removal of oversize products

Classification -Separating of two fractions at a specific screen size

Deagglomeration – Breaking of soft lumps into powders

Dedusting  Removal of ‘fines’ from feed products

Liquid Straining  Removal of excess liquid from solid product by straining through the sifter screen

Product Dressing & Conditioning Final dressing and conditioning of powder mixes to ensure optimum end product quality.

Special Applications

  • Flour sieving
  • In-line vacuum conveying
  • In-line positive pressure pneumatic conveying
  • Product recovery from packaging
  • De-agglomeration of dried fruits
  • Recovery of powder paint from spray booth
  • Insertable mini sifting
  • Extruder protection

Typical Industry Applications Include:

Food Processing Industry
