Why Mill?

• Kernel Hydration

• Enzyme Accessibility

• Release Starch from Fiber

• Open Grit Starch

• Release Starch from Germ

• Release Protein from Starch

• Release Protein from Germ

Starches – Retrograded/Resistive


RS1 – Encapsulated Starch

• Starch is bound within protein or fiber matrix approximately 250-300 microns in size.

• Treated by effective milling (~500 microns)

RS2 – Crystallized (short-chain) Amylopectin

• Resistant due to high density and crystalline structure. The amylopectin strands

form chain associations which are digested slowly but fully.

• Treated by effective cooking to open crystal structure and improve enzyme access

RS3 – Retrograded Amylose

• During heat processing in excess water, the amylose strands pack tightly to form a

strong crystal structure. The presence of thermo-stable alpha-amylase can enhance

this phenomena. The result is starch that is completely resistant to digestion.

• Not measureable using existing enzymatic test methods

• Treated by Effective cooking and avoidance of excessive alpha amylase during

cooking

Starches – Solution


Reduce Grit and Germ Size by grinding later

• Target >500 micron particles

MZSA PADDLE SCREEN PURPOSE

Separate solids and liquids based on incoming particle size

Displace liquid in cake with water to wash cake

OPERATION

Internal screen determines particle size separation

Paddles apply centrifugal forces to dewater and remove solids smaller than screen size

Internal wash nozzles displace remaining liquids to improve separation


IMPROVING WASHING Manage current plant water

input in more effective ways

Number of wash stages

Amount of water used in wash

Effectiveness of water usage
