Independent Peer Review Service for Bulk Solids Handling Systems

Jenike & Johanson of Tyngsborough, Massachusetts is pleased to announce its peer review service for bulk solids handling applications for a variety of industries and applications. A critical step in the design of bulk solids handling systems, a peer review is important when

Redundancy in processing design is lacking
Operation is related to public health and safety
Using new technology or design methods
Working with new or unique bulk solids

These types of situations requiring crucial performance and avoiding critical problems warrant the use of a peer review. Parties that can benefit include the operating company, major owner(s), operation insurer, main engineering firm, construction firm, and contract management firm. As an independent expert with no stake in the recommended outcome, Jenike & Johanson’s role in a solids handling peer review is to provide verification of:

Bulk solids flow assumptions and influences of site process and ambient conditions
Appropriate design procedures and analyses
Attainment of client’s needs and specifications regarding bulk solids processing
Feasibility and practicality of the process design
Solids handling effects on process or equipment

The peer review service is performed after the design phase is complete to ensure no engineering mistakes are present and appropriate effort has been made to develop a safe and cost-effective design. Furthermore, Jenike & Johanson will review the design to make certain the intended production objectives will be met. Examples of components reviewed include stockpiles, silos, hoppers, feeders, chutes, blenders and more.

Jenike & Johanson’s peer review service typically takes two to four weeks to complete depending on the type of system being evaluated, whether it is a new or existing system, and whether an on site trip is required. A written report is provided. Applications and industries utilizing peer review include pharmaceutical, energy, utilities, chemical, plastics, food processing and more.

Mixing and Blending of Powders

Obtaining a uniform blend of dry bulk solids is a problem faced daily by engineers and operators in industries as varied as pharmaceuticals, foods, plastics, and battery production.

Typically, selection of an industrial blender is not made based on scientific principles, rather, a blender is often chosen based on other factors, such as, equipment cost, relationship with a blending equipment supplier, or use of a previous model.

Although there are no first-principles mathematical solutions for selecting a blender, proven, practical guidelines do exist which aid in the process of selecting a blender vs. using a costly and time consuming trial-and-error approach.

Information provided by this lecture series can effectively help an engineer, formulator or plant operator with the mixing and blending fundamentals required to troubleshoot mixing difficulties or selection of equipment for a powder blending application

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.

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.
