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.
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.
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.
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.
