Title:
FLOW ASSESSMENT APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2008/125255
Kind Code:
A8
Abstract:
A flow assessment apparatus (10) is provided for quantitatively assessing the flow properties of particulate material, such as pharmaceutical formulations and constituent powders. The apparatus (10) includes a vibratory feed device (12) having an inclined dispensing member (16). Particulate material is induced to flow along the inclined member (16) onto a watch glass (18) positioned on a top pan balance (20). The mass of material dispensed onto the watch glass (18) is recorded over a given time period, for example a set time period of 1 minute, or a visually assessed time period where it is deemed that sufficient material has been dispensed. The mass and time data is used to calculate a value representative of a relative flow property of the material, which can be used in the development of pharmaceutical formulations.
