Rotary Screen (Centrifugal Sieve)

Description:

Rotary Screen, also known as a Centrifugal Sieve, is a vital piece of equipment in the starch processing industry, designed to efficiently separate starch slurry from fibrous materials. This machine is particularly effective for processing starches that are sticky in nature, such as those found in wheat and cassava starch production. The Rotary Screen operates with a conical-shaped basket, which is covered with a stainless-steel filter. As the basket rotates, starch milk is fed into the sieve, passing through the filter, while the fibres are separated and slide down the conical basket, exiting the machine.

The design of the rotary screen ensures that the starch is effectively separated from fibres, making it an ideal solution for starch slurry separation. The rotational speed and basket design can be adjusted to meet the specific requirements of different types of starch, ensuring optimal performance across various applications. This machine is also known for its ease of operation and can be constructed entirely from stainless steel, ensuring durability and compliance with food-grade standards.

Principle of Operation:

Rotary Screen features a conical-shaped basket that rotates at high speed. Starch milk is introduced into the basket, where it passes through a stainless-steel filter that covers the basket. As the basket turns, centrifugal force drives the finer starch particles through the filter, while the fibrous material is separated and slides down the conical basket, exiting through a discharge outlet. This process is particularly effective for separating sticky starches that tend to adhere to fibres, ensuring high efficiency in starch recovery.
