Hygienic and safe sifting

Dinnissen has developed sifting machines for various product types and processes, which meet all hygiene and safety requirements set within sectors such as feed and food. Our sifting machines can also be supplied with approval for ATEX Zone 20, so explosive substances can be processed safely. For the ultimate in ease of cleaning, we developed the Wingdoor Sifting System, with large opening doors allowing the operator to easily clean and inspect the entire machine. Another advantage is the ultra-fast changing of sifting baskets.

To check product at critical points in the production process, a vibrating sieve can be used. Several sieves can be mounted one above the other, while the machine stays maintenance-friendly and easy to clean. For minimal product damage, a Rotating Drum Sifting System can be chosen, which at low speed is very suitable for sifting grains and chunks. Feel free to contact one of our experts for a customized sifting solution.

Centrifugal Sifters

Available on request

Centrifugal Sifters are ideal for processing varying amounts of product. Thanks to the various setting possibilities and mesh openings between 250 and 2000 µm, different capacities -from a few kilograms per hour up to more than 39 tons per hour- can be processed with a single machine. The centrifugal force in the rotating drum ensures that the product to be sifted is pressed against the perforated drum wall. Only the product particles that are small enough pass through the holes in the drum wall. Depending on the type of product and the required size of the sifting surface, Dinnissen provides a solution that meets the desired capacity and integration into existing systems.

  • Suitable for different quantities
  • Mesh openings between 250 and 2000 µm
  • Integratable in existing conveyor systems

Rotary Drum Sifter

Available on request

While a Centrifugal Screening Machine mainly processes powders, a Rotary Drum Screening Machine is used for sifting grains and chunks. What makes the Rotary Drum Screener so suitable for this is its relatively low RPM of less than 1 meter per second. This prevents product damage and ensures compliance with the applicable ATEX guidelines.

  • Minimal product damage
  • Highly suitable for food, pet food, and feed
  • In accordance with ATEX guidelines

Wingdoor Sifter

Available on request

The large inspection hatches of the Wingdoor Sifter allow the operator to access all relevant parts quickly and easily for inspection and maintenance. In addition, sifting baskets can be replaced ultra-quickly. This is the reason that when there are many product changes, the Wingdoor Sifter is preferred. Because of its ergonomic design, cleaning the sifter does not take much time and effort from the operator. And because the sifting baskets can be replaced ultra-fast, it is possible to change quickly between products.  

  • Suitable for many product changes
  • Designed for ultra-fast sifting basket changes
  • Easy to clean due to large inspection hatches

More about this solution

Vibrating Sifters

Available on request

This machine is ideally suitable for sifting granular materials. A Vibrating Sifter with several sifters can divide a product into several groups. Because the sifting deck is vibrated, the smaller product particles fall through the sifting deck via the sifting perforations. The large grains remain on the sifting deck. When multiple sifters are used, the top sifter has the largest perforations - leaving only the very largest materials behind - and the sifters become finer and finer as they are installed downwards.

  • More or fewer sifting decks can be used depending on the application
  • Separation into many components is possible
  • The sifting process can be controlled well, including for large to extremely large capacities
