Starch Washing Systems

Starch washing consists of separating starch particles from soluble and insoluble proteins. Radial matrix starch washing units contain a variable number of cyclonettes (small cyclones) that function as centrifugal separation devices. Cyclonettes are mounted between two concentric stainless-steel cylinder cartridges that form three separate chambers including, feed slurry, underflow stream, and overflow stream.

CYCLONETTE GEOMETRY

Cyclonettes have a conical interior chamber with an inlet (feed hole) in the edge of the large end (base) of the cone and outlet holes in the centers of the small end (apex) and of the base. Because the feed hole is tangential to the curve of the interior surface, slurry introduced under pressure through the feed hole begins spinning smoothly around the cone’s surface toward the small end.

Spinning action creates centrifugal forces on slurry, causing heavier (higher specific gravity) particles and liquids (blue spiral) to migrate outward, closer to cone’s interior surface.

As slurry spins toward apex, decreasing available space forces inner, lighter portion (red spiral) of slurry to reverse direction and travel back toward and through overflow outlet at base.

The outer portion of the slurry flow continues toward the apex and through underflow outlet.

PRINCIPLES OF OPERATION

The goal of starch washing is to separate starch particles from soluble and insoluble proteins. Starch washing units can contain a variable number of cyclonettes (small cyclones) that function as centrifugal separation devices. Cyclonettes are mounted across two parallel stainless-steel discs within a stainless steel case to form three separate chambers for feed slurry input and for underflow and overflow output streams.

Radial Matrix

Fluid Quip’s RM-12 Radial matrix washer allows for customization, for specific process needs. Radial Matrix units are available in many configurations such as RM-12, and RM-22. The number of cyclonettes can be changed with customized cartridge sizes. Fluid Quip also supplies expansion cartridges for units already in service. Talk to an associate to see how we can improve your starch washing efficiency.

Single Matrix Unit (SMU) and Dual Matrix Units (DMU)

Fluid-Quip offers a range of SMU and DMU units depending on the capacity required and budget of the project. The SMU and DMU starch washing units are designed for smaller washing lines, or recovery applications. Production units range from 60 open cyclonettes (SMU-60) to 332 open cyclonettes (DMU-332).

Fluid-Quip offers full service of starch washing design and manufacture. We provide design, balance with expected results, and after sale support to optimize starch washing systems.

Radial Matrix 12″ (RM-12) and Radial Matrix 22″ (RM-22)

Fluid-Quip offers a wide range of Radial Matrix Starch Washing Units depending on the capacity required and budget of the project. Production units range from 144 open cyclonettes (RM-12-144) to 2000+ open cyclonettes (RM-22-2100).  These units are designed to be compact, with easy connection for piping.
