The Wingdoor sifter is an ergonomically designed sifting machine that is named after the large inspection hatches that can be folded open like wings. The Wingdoor screening machine can process up to 30 tons per hour and can be set for various grain sizes. The mesh openings vary between 250 and 2000 µm.
Process:
Sifting & ScreeningThe 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.
Not all products can be sifted with the same size mesh openings. The diameter of the holes in the sifting basket depends on the desired fineness of the product that is to be sifted. Setting up a sifter per product is not only expensive but also unsustainable and unnecessary. It is much more practical to choose a sifter that is suitable for multiple product types and grain sizes. The Wingdoor Sifter can sift more than one product type. Because of the speed at which the sifting baskets can be replaced, the Wingdoor Sifter is ideally suited for processing different products and grain sizes. Another advantage of the Wingdoor Sifter is the ease by which an operator can access all parts. The sifter is quickly and safely accessible by opening two large inspection hatches. The design of the sifter ensures an ergonomic workplace for the operator.
The Wingdoor Sifter is a centrifugal sifter, which separates particles by the force with which these particles are pressed against the drum. A sifting perforation is installed in the drum. The smaller grains disappear from the drum through the perforation holes. Grains that are too large will remain in the drum. The sifting perforation can be adjusted to the desired final fineness of the product that has to be sifted. The Wingdoor Sifter can be integrated into existing conveyor systems, tailored to the existing line and the desired sifting results.
The Wingdoor Sifter distinguishes itself by its large inspection doors, which can be opened upwards. This ergonomic design allows operators quick and easy access to all important parts. In addition, the sifting baskets can be replaced ultra-fast. These features ensure that the Wingdoor Screening Machine is often used in processes involving many product changes.
The foundation of the Wingdoor Sifter is a cylindrical sifting basket. The basket rotates on its axis and the centrifugal force created by the rotation of the sifter presses grains or powders against the basket. There are perforation holes in the basket, the size of these depends on the desired final fineness of the product to be sifted. Because the product is pressed against the basket, grains or powders that are small enough to pass through the perforation holes disappear from the basket. The product that is too large to be flung through the holes remains in the basket. In this way, large quantities of product can be sifted quickly.
The large wing-shaped opening inspection hatches allow the basket to be replaced quickly and efficiently with a basket with a different perforation diameter. In addition, this allows the screening machine to be thoroughly cleaned. This also makes the Wingdoor Sifter very suitable for processing powders, grains and granulates where hygiene is extremely important.
