As the name "Vibrating Sifter" suggests, vibration is used to achieve the separation of a mixture of granular materials. A Vibrating Sifter is also called a flat sifter or a shaking sifter. Dinnissen has various Vibrating Sifters available, depending on the product to be sifted and the desired result.
Process:
SiftingThis 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.
In the feed and food industry, all processes must comply with strict requirements. Before a product is processed into a final product, a Vibrating Sifter can be used as a kind of control sifter to filter out the last contaminants from the product stream. The Vibrating Sifter helps producers at critical control points (CCPs) within the production process. A critical control point is a step in the food production process that can be used for (additional) control of the product flow. Critical control points are essential to verify that food safety is being maintained. A Vibrating Sifter from Dinnissen ensures that contaminants do not get a chance to be processed into the final product and removes dust in the product flow.
Every Vibrating Sifter contains a screening deck with horizontal vibration. Due to this vibration of this sifting deck, the smaller particles on the sifting deck fall through the sifting deck via the perforations. The larger particles remain on the sifting deck. There are various versions of the Vibrating Sifter. For example, several sifters can be mounted on top of each other. This creates different groups of product, selected for fineness. In addition, the sifting deck can move vertically, as well as horizontally.
The Vibrating Sifter can ensure that the product that cannot pass through the sifter perforations is moved horizontally by the vibration. As a result, this machine is also referred to as a vibrating sifter. Dinnissen's Vibrating Sifters are available in different (round and rectangular) versions, in various material types, including specific cleaning options with air, impact or ultrasonic vibrations. Ultrasonic vibrations create a more uniform movement, and the grains pass more easily through the perforations of the screening deck. This technique reduces the chance of clogging the sifting deck.
In a Vibrating Sifter, vibration is used to achieve separation of a mixture of granular materials. Vibrating the vibrating deck causes the material to move. The material that is fine enough falls through the perforations of the sifting deck. The mixtures to be sifted are often fed in by dosed dumping. The Vibrating Sifter should be mounted on a solid surface to prevent secondary vibrations from occurring at all. For different materials, parameters such as sifting angle, adjustment angle and imbalance of the vibrating motors can be easily adjusted and documented.

In addition to Vibrating Sifters, we also have sifters in house that work based on centrifugal force. In addition, we have developed the Wingdoor Sifter, a machine that is easy to clean because of the opening doors. We will be happy to advise you on the best solution to achieve the desired sifting result.
System integrator Dinnissen optimizes and innovates your production process with tailored solutions: developed, manufactured and tested in-house. From product intake, transport, dosing and weighing, mixing, grinding, sieving and packaging to full automation and control. We maximize the performance and efficiency of your entire process.
The importance of hygiene and safety requirements
Dinnissen fully understood the importance of hygiene and safety requirements in our industry. They went the extra mile by providing us with all the necessary documentation, all ATEX drawings, and full traceability.
