“Solids handling: lab, lecture, and lunch” – July 15, 2010

Back by popular demand, Jenike & Johanson engineers will be delivering the 7th annual 1 day seminar at their Tyngsboro, Massachusetts office/laboratory regarding fundamental aspects of bulk solids handling, testing, and pneumatic conveying. There will also be an offering for this course in our San Luis Obispo, California office on November 4, 2010.

This informative workshop will provide insights into common flow problems that arise when bulk solids are put into silos, bins, and hoppers. Scientific methods to characterize a material's flow properties will be demonstrated in our laboratory along with discussion of proven, practical, and cost effective design solutions for common bulk solids handling equipment.

Proper training of personnel involved in solids handling and processing is essential to operating an efficient and reliable bulk solids handling system. Since the theory of bulk solids handling is seldom a part of formal engineering training, many in industry lack an understanding of why solids handling problems occur and what practical steps can be taken to diagnose, alleviate, or prevent them. This workshop provides fundamental principles essential for any personnel dealing with bulk solids.

Webinar: Addressing Variation in Blend and Content Uniformity Data in Compression/Encapsulation Processes on June 22, 2010

Jenike & Johanson engineers will be presenting a Webinar addressing variations in blend and content uniformity data in compression/encapsulation processes on June 22, 2010, sponsored by Tablets & Capsules.

Pharmaceutical scientists are responsible for developing formulas and designing processes that ensure the content uniformity of tablets and capsules. Unfortunately, a number of scientists who formulate products and select and/or design processing equipment lack in-depth understanding of powder blending and segregation. As a result, processes may be developed that are not capable of providing the required blend uniformity (BU) and content uniformity (CU) of the dosage units. This can result in significant costs, production inefficiency and delays to market.

This webinar will outline a methodology for identifying and addressing different categories of BU and CU (tablet) variation.

Learn about the flow of bulk solids in bins, hoppers, feeders and their pneumatic transport at ASME/AIChE in Las Vegas, Nevada on March 15-17 and Houston, Texas on June 7-9

Jenike & Johanson engineers will be presenting their popular powder and bulk solids handling courses for ASME/AIChE in Las Vegas, Nevada on March 15-17 and Houston, Texas on June 7-9.

The training will include discussion of hopper flow patterns, testing of powder flow properties and their relation to silo and hopper design, feeder design principles, handling of fine powders and fluidization, segregation of bulk solids, transfer chute design, and the proper use of flow aids. The third day will include a discussion of the fundamentals of pneumatic transport and how to troubleshoot and solve problems with a poorly operating pneumatic conveying system.

Proper training of personnel involved in solids handling and processing is essential to operating an efficient and reliable bulk solids handling system. Since the theory of bulk solids handling is seldom a part of formal engineering training, many in industry lack an understanding of why solids handling problems occur and what practical steps can be taken to diagnose, alleviate, or prevent them. Training helps to foster greater awareness of operating efficiency, safety, and process improvement, along with an understanding of the reasoning behind required equipment modifications or upgrades.

Acquire valuable powder processing knowledge at Interphex 2010 on April 21

James K. Prescott, a Senior Consultant with Jenike & Johanson, will be discussing “Developing Robust Manufacturing Processes For Direct-Compression Operations” at the upcoming Interphex 2010 in New York City in April 20-22, 2010.

Direct compression tableting operations rely on obtaining a uniform blend of multiple components, and transferring that blend reliably from the blending operation to compression. Low dose products can be susceptible to segregation and sampling errors, while high dose products can be susceptible to erratic flow, weight variations, and feed rate limitations. Demonstrating that these manufacturing processes are robust, and establishing their design spaces, is essential to minimizing risk before heading into validation.

Process understanding can be gained via trial-and-error; however, if built on first-principle behaviors, uncertainty is significantly reduced. Discussions will include how to set design specifications and establish design spaces for materials and equipment, as related to powder storage, handling and transfer behaviors in manufacturing.

J&J presenting results of analytical tool used to successfully predict pharmaceutical production scale performance at AAPS Annual Meeting in Los Angeles, CA, on Nov 9, 2009

James K. Prescott of Jenike & Johanson, Inc. is presenting the results of using “Segregation Tests on a Direct Compressible Blend as a Tool to Evaluate Potential Content Uniformity Problems” at the Papers Poster Session at the AAPS (American Association of Pharmaceutical Scientists) Annual Meeting in Los Angeles, CA, on Nov 9, 2009. This work was performed in collaboration with Pfizer, Inc.

Segregation tests at the bench scale were conduced on a direct-compression formulation to predict and understand segregation behaviors of a direct-compression blend at a production scale. As a result of the high segregation tendencies that were found, a Design of Experiment (DOE) was run to investigate factors that could influence content uniformity at the production scale, and to identify controls required to maintain uniformity. Visual assessments of the blend showed segregation tendencies. Bench-scale segregation tests at the development scale quantified the relative severity of segregation and identified fluidization as the predominant mechanism. This provided emphasis that right-first-time and quality-by-design methods are required for this formulation to ensure successful production.
