Quadrumat^® Senior

Application

The Brabender^® Quadrumat^® Senior is a laboratory mill for
manifold applications:

• Preparation of productionequivalent test flours
• Determination of the milling properties of manifold sorts of grain (wheat, rye, and others)
• Determination of the potential yield

Principle

The Quadrumat^® Senior uses the same 4-roll principle as the Brabender^® Quadrumat^® Junior with, however, two parallel 4-roll units:

• A break head
• A grinding or middlings reduction head

A bipartite plansifter with the two sifter sections, stacked one above the other, separates the fractions according to their granulation. Each sifter section produces either a single joint flour or two separate flours.
