Powder Flow: A QbD approach to Continuous Tablet Manufacture Tim Freeman
January 16, 2020
Utilising the FT4 Powder Rheometer® and the GEA ConsiGmaTM Twin Screw High Shear Granulator
Powder Flow: Characterising Wet Masses using the FT4 Powder Rheometer Tim Freeman
December 13, 2019
The presence of free water can fundamentally influence the flow properties of a powder.
Powder Flow: The Influence of Flow Additives on Powder Behaviour Tim Freeman
November 14, 2019
Many powders have poor basic flow properties: They block in hoppers and die feed frames, exhibit inconsistent or pulsatile discharge rates, adhere to surfaces of equipment or don’t mix readily with other materials.
Powder Flow：The importance of a sachet filling process with low weight variation and high content uniformity Tim Freeman
September 25, 2019
It is imperative that the sachet filling process produces consistent, uniform fill throughout an entire production run, with low weight variation and high content uniformity.
Powder Flow: Particle Size-independent Variation of Bulk Excipients Tim Freeman
August 12, 2019
Microcrystalline Cellulose (MCC) has been used as a pharmaceutical excipient for many years, due to its abundance, ease of production and resistance to degradation.
Powder Flow: The Influence of Roller Compactor Process Parameters on Granule Properties Tim Freeman
July 17, 2019
Dry granulation by roller compaction is a continuous process applied routinely to convert fine, difficult to handle powders into uniform granular products that flow freely and perform efficiently in subsequent manufacturing steps.
Powder Flow: The Influence of Storage and Handling Tim Freeman
June 26, 2019
When working with powders, in-process performance and final product quality will be influenced by properties of the raw materials delivered to the process.
Powder Flow: The Influence of Particle Size and Shape on Flow Properties Tim Freeman
April 17, 2019
The size and shape of the particles within a powder are important factors in influencing behaviour, and many well-established techniques exist for measuring these properties.
Powder Flow: Batch Variability in spray coating Applications Tim Freeman
March 08, 2019
In spray coating applications, a fine powder, typically a polymer, is drawn from a storage device before being fluidised and ejected through a charged nozzle onto a substrate.
Powder Flow: Developing a Design Space for a Die Filling Operation Tim Freeman
February 19, 2019
Filling is a common operation across all industries, although fill weights and tolerances vary widely.
