Cyclone System

Description:

Cyclone System is an integral component in starch processing, designed for the efficient separation and removal of various impurities and components from starch slurry. The system typically comprises specialised cyclones such as germ cyclones and desanding cyclones, each playing a vital role in ensuring the purity and quality of the starch by removing unwanted materials like sand, metal particles, and corn germ.

Germ Cyclone: Germ cyclone is specifically used to separate corn germ from the starch slurry produced by cracking steeped corn kernels. Utilising turbulent centrifugal force, the germ cyclone effectively separates the lighter germ, which contains most of the corn's oil, from the heavier starch and fibre. This separation process is critical in ensuring the high recovery of both starch and germ. The starch slurry is pumped tangentially into the cyclone at a velocity that creates a swirling vortex. The lighter germ is directed to the central overflow outlet, while the heavier starch and fibre are forced outward against the inner wall, exiting through the underflow. Multiple cyclones can be connected in series or parallel for optimal separation efficiency.

Desanding Cyclone: Desanding cyclone, also known as a destoner, is essential for removing abrasive materials such as sand, stone, and metal particles from the starch slurry. This step is crucial in protecting downstream equipment from wear and damage caused by these coarse particles. The desander operates on the cyclone principle, where the slurry is pumped into the cyclone, initiating a rotational motion that, through centrifugal force, drives heavy particles toward the outer wall. These particles are then collected in a conical settling tank for easy removal, while the purified slurry exits through an upper outlet nozzle.
