Product Overview

Laboratory Milling of Both Hard & Soft Wheats

The CHOPIN Technologies LabMill is a laboratory mill used to transform both hard and soft wheat into refined flour to examine its milling behaviour and the quality of the flour produced. The biochemical composition of the flours processed by the LabMill is very close to that of industrial flours (purity, granulometry, histological composition, starch damage, quality and quantity of protein).

Benefits

  • Anticipate the behavior of wheat in an industrial mill (extraction potential and flour quality)
  • Facilitates and secures wheat purchases by allowing the miller to make a choice according to the quality of the produced flour and the way in which the flour is obtained (milling value). For equivalent flour quality, the miller can choose the wheat that best suits their milling process
  • Ideal tool to produce flours adapted (quantity and quality) to the realization of bread-making tests

Applications

A Modern and Versatile Mill

The LabMill is Used in the Wheat Industry for Assessing Milling Quality & Produced Flour Quality

Millers

For millers, the LabMill assists with the wheat selection, based on its milling value and the quality of the produced flour. Millers also use the instrument to assist with their wheat blends. They can optimize wheat tempering by adjusting the moisture level and resting time for several batches.Select optimal wheat according to properties best suited to your milling process AND the final flour quality.

Ingredient Specialists & Recipe Development

With its large milling capacity (up to 3.5 Kg of wheat), combined with its high extraction rate, the LabMill generates enough flour for bread-making tests with their enzymes, additives, etc.

The high extraction rate of LabMill also has the advantage of producing flour that is close to industrial flour (peripheral proteins, enzymes, etc.), which is an additional advantage when conducting bread-making tests.

Research & Educational Institutes

The LabMill is the ideal tool for training in milling and for conducting technical and scientific studies:

  • Its operating principle (succession of grinding and sieving) is representative of that of an industrial mill and makes it easy to understand the basic principles of milling
  • Its milling diagram is complete (breaking, sizing and reduction steps) with combined grooved and smooth rolls, which makes it possible to better understand the role of these various stages
  • Its configuration allows you to recover, quantify and study all the milling products (streams flours, middlings and brans)
  • Its flexibility (streams, flow rate, sieves and rolls adjustments) allows the study of the many parameters influencing the result of a milling process (both quality and quantity)

How It Works

Gradual Milling with a Dedicated & Patented Diagram

Although on a reduced scale, the LabMill’s operating principle is similar to that of an industrial mill: the grain is ground in a series of rollermills to remove the bran and to cut the endosperm. Between each rollermill cycle, the ground grain is sifted and separated into various sizes. With this procedure, the LabMill produces a flour that is representative (purity, granulometry, histological composition, starch damage, quality, and quantity of protein) of product produced by a commercial industrial mill and can be used for all your rheological analyses.

The LabMill’s innovative patented milling diagram is comprised of 5 (or 6) consecutive steps:

  • 2 breaking steps, between grooved rollers, to make flour, fine middlings, coarse middlings, and bran
  • 1 sizing step, between smooth rollers, to reduce coarse middlings to flour, fine middlings, and fine bran
  • 2 (or 3) reduction steps, between smooth rollers, to reduce fine middlings to flour

LabMill was developed within the Milling Quality Consortium (AFSA, Arvalis-institut du végétal, ANMF, Danone Vitapole, INRA, IRTAC, Ulice, CHOPIN Technologies).

System Components

A Complete and Compact Mill

All access is through the top and front of the device, making it easy to carry out all analysis and maintenance operations in optimal ergonomic conditions.

The LabMill incorporates innovations allowing for the combination of performance, precision, reproducibility, sturdiness, and ease of use. 

Adjustable Settings

  • Equipped with a precise scale, LabMill’s feed system releases a constant flow of grain, adapted to every type of wheat. Flow rate is easily configurable by the operator using a user-friendly control interface
  • Sifting time for each stream is easily configurable by the operator using the user-friendly control interface
  • Beater bar orientation (extraction or retention) allows you to adapt the sifting quality *
  • The cylinders are mounted on eccentric bearings, which allows for special adjustments*

* Adjusting beater bar orientation and cylinder gap requires specific tools & knowledge and specific training by a CHOPIN expert

Performance

  • Extraction rate
  • ~The extraction rate obtained on the LabMill is particularly high compared to its short milling diagram. This extraction rate is between 65% and 80%, with an average of around 75%.
  • Purity
  • ~Flour purity is traditionally measured by ash content. In LabMill’s case, it is between 0.50% and 0.65%/ms, which corresponds to a 55 ash flour commonly used in bread-making.
  • Flour Quality
  • ~With its factory settings, the LabMill produces a flour quality comparable (in terms of Alveograph results) to that produced by a CD1 Mill according to the ISO 27971 standard.

These performances are dependent on the type of wheat used, the wheat tempering method, and the adjustments made to the LabMill.
