HYGIENIC DESIGN,  SCREENING

The internal screw of the centrifugal ensures the metering and  the sending of the material into the cylindrical grid. Outside of this grid, a rotating shaft with blades spreads the product against its walls. Thanks to centrifugal force, the sieved material passesthrough the mesh and the exiSting foreign bodies are trapped by
the mesh and conveyed towards the discharge spout.

Sievıng - Maxımum control for optImal results

Companies in the food, feed, pharma and chemical industries are being confronted with increasingly stringent requirements with regard to food safety, quality, tracking & tracing and hazards associated with dust and explosions. So it should come as no surprise that DOSERAY Process Technology is continually searching for the best solutions when it comes to quickly and reliably managing various granulated as well as powdered materials. Effi cient fractionation ensures the highest purity Our sieving technique is based on the use of our centrifugal sieves.

OUR SIEVE TECHNOLOGY

Dry or moist bulk solid material is gravity-fed into the feed inlet and redirected into the cylindrical sifting chamber by means of a feed screw. Rotating helical paddles within the chamber continuously propel the material against the screen, while the resultant, centrifugal force on the particles accelerates them through the apertures. On-size particles are funneled through a discharge housing equipped with an inspection door, while oversized particles and trash are propelled through the screen cylinder and ejected through a discharge spout.  In addition to sifting and scalping of dry bulk materials, the screener can break up soft agglomerates and/or dewater moist solids or slurries.

HOW DOES CENTRIFUGAL ROTARY  CONTROL SIFTER WORK?

We also apply vibration and conical pneumatic screening technologies in your pneumatic transfer processes and silobuses. Thanks to the conical screens in the range of our products which are installed at the highest level of the silos, we prevent ingress of foreign objects into your silos. Foreign materials especially sand, calcite and similar materials in the construction chemicals may give damage to the screws and mixers, other transport equipment of the process. For this reason, the raw material introduced in the process should be screened definitely.  A paddle assembly rotates at high speed inside a stationary cylindrical screen and the material passes through the static screen by centrifugal action. The waste material is ejected toward the outlet located at the end of the screen basket. Our centrifugal sieves guarantee high sanitation standards and the respect of the quality of the handled materials.

Designed to Produce High-Quality Products
Removes foreign material from powders and granular products, such as flour and sugar. The fine particles pass through the sieve. The bigger, coarser particles fall over the end of the sieve screen and are separated from the product.

Designed to deliver high quality, uniform end products.
The centrifugal sieve DSR-SIFT200 pushes material entering the unit against the screen jacket while simultaneously conveying it slowly toward the outlet, thereby disintegrating even smaller lumps. This results in exceptionally clean, high quality products.
Guarantees uniform particle sizes and end products free of contaminants when applied as a control sieve.
Excellent operating efficiency through continuous self-cleaning.

Brushes attached to the rotor clean the screen, ensuring a high separating efficiency. Active sieving area up to 320 dm² (for standart product) , depending on machine model.
Top sanitation through easy cleaning.

The centrifugal sieve’s design enables high sanitation standards thanks to easy access for cleaning and maintenance.

 

  • centrifugal sifter

  • The material to be fractionated is brought into the sieving chamber, where the material is agitated by spinning fi ns. Those fractions which consist of small enough particles pass through the centrifugal sieve, whereas contaminants and larger particles are quickly transported onwards. By varying the rotation speed as well as the diameter of the openings and the path length of the sieve, we can realize any desired sieving result. And our broad range of  accessories and options makes it possible to realize the necessary level of quality, safety and hygiene for any situation.

HYGENIC DESIGn CentrIfugal SIfter

The machine housing and the screens are completely made of stainless steel. A new tangential inlet without screws prevents product from accumulating in the inlet. This makes the inline check sieve the perfect choice for use in the finished product section.

Use For A Wide Range Of Applications
Screen holes range from 0.6 to 10 mm. It is used in mills, bakeries and other industrial food processing, to sift wholegrain flour, cake flour, bakery flour, cornstarch, durum semolina and crystal sugar. Designed for pneumatic systems.

SIFTING PRINCIPLE OF OPERATION

Material is fed into the feed inlet and redirected into the cylindrical sifting chamber by means of a feed screw. Rotating, helical paddles within the chamber continuously propel the material against the screen, while the resultant, centrifugal force on the particles accelerates them through the apertures. These rotating paddles, which never make contact with the screen, also serve to breakup soft agglomerates. Over-sized particles and trash are ejected via the oversize discharge spout.

EASY MAINTENANCE
A new direct drive replaces the previous belt transmission.This increases the machine uptime by eliminating the need for replacing and retensioning the belt.

 Our centrifugal sieve or rotary sifter enables the separation of foreign objects from powders and granulates. A paddle assembly rotates at high speed inside a stationary cylindrical screen and the material passes through the static screen by centrifugal action. The waste material is ejected toward the outlet located at the end of the screen basket. Our centrifugal sieves guarantee high sanitation standards and the respect of the quality of the handled materials.
