Stable Micro Systems Ltd. use the test frame and vertical drive system provided by a universal Texture Analyser, and add the rotational drive and software functionality to form the Powder Flow Analyser - an accurate and reliable method of measuring the flow characteristics of powders.

Powder Flow Analysers can be purchased as completely new working systems, or you can take your existing Texture Analyser and attach the Powder Flow Analyser to extend your range of testing solutions from powders to end products.

A patented helically machined rotor can be programmed to move through a powder column in different ways, depending upon the characteristic that is to be measured. Due to the unique precision profile of the rotor's blade, the sample can be physically displaced in many different ways. The Test Settings of blade path angle and tip speed determine the mode of Controlled Flow achieved within a sample column.

During the test, axial force, time and distance are measured by a sensitive transducer and data is displayed and analysed in real time by Exponent software. Sample results can be ranked and compared to assess the impact of external conditions including humidity and moisture content, surface properties, electrostatic charge and particle or granule size, shape and distribution. Manufacturers can assess and avoid typical problems such as batch and source variation of ingredients, caking during storage or transportation and problems with discharging from hoppers or bins.

Once programmed, the optimised test can provide identical controlled flow conditions when completing the same test programme. Test Settings can be optimised to show the maximum differentiation between similar products, or to imitate the process or storage handling conditions, experienced by the product.

The Powder Flow Analyser is supplied with library tests, so operators can start testing quickly and conveniently after straightforward installation and calibration. Users can, however, fully program the instrument to carry out slicing, shearing, compressing, compacting and aerating cycles in any combination.
