Quadrumat® Senior

Application

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

• Preparation of production equivalent 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.

Advantages

Superior process-technical features have made the Quadrumat® Senior one of the most commonly used instruments of its kind all over the world

• Production of 4 milling products altogether:
- Break flour
- Reduction flour
- Shorts
- Bran

• High performance and gentle milling by a 4-roll milling system with hardened, profile-ground rolls
• 2 x 3 successive roll passes in a single step
• No intermediate sifting required
• Self-cleaning sifter
• Easy operation and handling
• Good reproducibility and constancy
• Throughput 8 - 10 kg/h
• Yield 65 - 75%
• With Brabender® Bran Duster up to 80%
• With Brabender® Bran Duster up to 80%
• Ash 0.45 - 0.65% on dry basis

The Quadrumat® Senior semolina mill

A modified version of the Quadrumat® Senior with modified rolls and roll gaps and with another sifter is available for grinding durum wheat to semolina.

Bran Duster

Application

The Bran Duster is for optimizing the flour yield. Sometimes, the ash content and yield of the grain sample do not meet the required specification.

It carefully separates flour particles still adhering to the bran - increase the yield obtained on your Quadrumat® Senior by some 10% and approach even better the ash content of your samples to that of commercial flours.

Principle

The sample material is filled through the feed hopper. The bran particles repeatedly hit onto the whirl battens so that any flour particle adhering to the bran are separated carefully from the bran and sifted through the round sieve.

Advantages

Flours can be tested on laboratory scale with respect to quality as they would also occur in mills.

• Higher flour yield
• Precise adjustment of ash content
• Smooth separation
• Speed 2830 min-1 at 50 HZ / 3400 min-1 at 60 Hz.
• Mesh size 200 µm (further dimensions on request)
