About the course

Covid-19 Statement
Please be advised that we continue to monitor the situation closely and are following government advice and guidance around Coronavirus (Covid-19).  All of our courses are subject to changes or cancellation.

We are aware that there are still many unknowns around the outbreak and we will keep all registered delegates and speakers up to date with any potential changes to the course as a result. What we are able to deliver will be subject to the guidance in place at the time of the course. We will ensure that any relevant safety and hygiene measures are in place and accept bookings on the basis that delegates agree to adhere to any social distancing and other guidance in place at the time of the course.

Please note, if restrictions do not permit us to commence the course face to face we may need to deliver some of the sessions online.

In line with our terms and conditions, if the University makes the decision to postpone or cancel the course, delegates will have the option to either defer their booking to the new date or to receive a full refund.

Limit on delegate numbers
Depending on restrictions in place in February along with other social distancing guidelines which may be in place during the course, we may need to limit the number of delegates we can register for 2021.

If we do need to reduce our delegate numbers we will be accepting bookings on a first come first served basis. If we need to cancel your booking we will inform you at least six weeks prior to the course and a full refund will be issued.

Please wait to receive an email from confirming your place before you book any travel to the course (if applicable) – please note that after booking you will receive an automatic confirmation of payment from the online store however this is not confirmation that we are able to accept you onto the course.

Our apologies for being unable to offer further guarantee of places at this stage, however we hope you understand that our highest priority is the safety of our delegates, speakers and staff.

What will I learn?
Powder flow and its significance in selecting the most appropriate mixers will be discussed. Quality assurance, powder sampling techniques, a practical discussion of the statistics of mixing and the value of statistics at the formulation stage will be covered. The handling, packaging and marketing of powder products will also be discussed.

This means that on completion of the course you’ll have an understanding of:

  • the relevance of powder flow to the mixing process

  • the concepts of free-flowing, cohesive, segregating, structured and coated powder systems

  • how to practically and theoretically assess the quality of a powder mixture

  • how to specify equipment fit for purpose.

How will I benefit?
Emphasis throughout is on the industrial application of basic principles. You’ll be given extensive interactive notes, and demonstrations, case studies and theory will be introduced wherever relevant.

Who should attend?

This course is relevant to you if you’re concerned with quality assurance and the improvement of existing processes or if you’re developing new product formulations and processes. It will be of particular interest if you work in any of the following industries:

  • food
