This instrument is used to investigate flour functionality and provides information on the visco-elastic properties of the dough. Air pressure is applied leading to deformation of the dough in 3 dimensions. The resultant variations in pressure are recorded to determine dough resistance and extensibility. The instrument can be used to classify wheat or flour according to their end use, monitor or compare wheat or flour quality, troubleshoot end-product issues related to flour functionality.


The Bühler mill is six stream adjustable laboratory scale roller mill for the production of white flour. We have four MLU-202s that are calibrated for use with wheat but they can be adjusted for use with other cereals or products when needed. Minimum sample size of 2kg and an average through-put of 6 kg hour-1.

This bench-top instrument uses X-rays to provide high resolution, non-destructive, 3D imaging of the internal structure of samples. Our Bruker 1172 instrument has a field of view of up to 65mm diameter and a maximum resolution of 1 micrometre. 3D images can be viewed interactively on a computer screen, digitally sliced to view any chosen region, and exported as CAD files or movies for visualisation. Measurements can be made of properties such as dimensions, porosity, and size distributions of bubbles or particles.

Applications include raw material structure in products such as nuts and grains, characterisation of porous products such as doughs, snacks, confectionery and baked products, distribution of salt particles, and measurement of faults in plastic packaging materials.

The Alvan Blanch IH15 is a high powered impact dehuller using a rotating blunt blade to crack the hulls off many cereals and legumes.

This system is used to take accurate colour images of products. Reliable comparisons can be made between samples imaged on different occasions, and prints can be produced that are an accurate reproduction of the original sample appearance. The system includes a digital camera, controlled illumination conditions, and a printer. The system is calibrated against the CIELAB L*, a*, b* colour scale. Image analysis software enables colour measurements of selected regions of a sample to be made against this scale. Applications include documentation of product appearance for production or storage trials, colour measurement, and production of images for product specification.

Clean and separate grain of dust, chaff and other big and small particles. Speed can be adjusted to feed and air rate, depending on the grain. Can be used for different types of grain: hard red spring, red durum, white, hard red winter, soft red winter, durum-white, rye, corn, barley, flax and grain sorghums.

A hyperspectral near infrared imaging system is used to map the spatial distribution of composition in samples. The system takes images in which each pixel contains an NIR spectrum. By prior calibration against reference samples of the chosen product type, properties such as moisture, fat or protein content can be mapped at each position in a sample. Samples of between a few millimetres and 30cm width can be measured in a few seconds. Common applications include measurement of fat distribution or moisture migration over shelf life for product development trials. The system can be transported for at-line analysis of samples at production sites or pilot plants.

The Farleygreene Sievmaster is a single pass vibrating sieve chamber with a diameter of 60cm. Sieves can be made with a wide range of apertures to work with the samples as required. This equipment is used for larger scale sieving and fractionation due to its larger size and gentle vibration.

This Qicpic system uses image analysis to measure the size and shape of particles. Coarse samples are gravity fed, and finer particles can be dispersed in air or a liquid for measurement. Size distributions can be measured for particles in the range from 2 micrometres to 30mm. For smaller particles, other facilities are also available at Campden BRI. A range of shape parameters are also measured for each particle, providing information on properties such as agglomeration or fibre lengths. Applications include nuts, seeds, grain, emulsions, and ground materials such as flour and other powders, herbs, spices, salt, and sugar.

The Russell Demi Finex A14550 is a vibrating sieve chamber with a fitted 300µm sieve. It is used as a final purification step of white flour after roller milling to remove any large particles retained from flour finishing.

Our small–scale roaster is ideal for evaluation of coffees, as well as training in different approaches to roasting coffee.

The Vario mill is a single pass roller mill used mainly for milling research with all kinds of raw materials due its ability to adjust and modify many of the milling properties/settings. Roll speed and differential, roll surface type, roll angle and gap can all be adjusted to create a range of different products. Used for rolling, flaking and milling many different types of cereals and legumes.
