Buhler Technology Group acquires Aeroglide

Uzwil, Switzerland -- The Buhler Technology Group has acquired all the shares of the U.S. firm Aeroglide Inc. through the signing and closing of a definitive agreement with U.S.-based, Compass Diversified Holdings (CODI).

Aeroglide, a mechanical engineering company that is a market leader in the field of drying and other thermal processes, is active in the food, feed, and industrial sectors. Aeroglide has supplemented the Buhler product range for years as a supplier. The acquisition will enable the future joint development of optimally matched solutions. Buhler will operate Aeroglide as an autonomous center of competence in the form of a business unit.

Aeroglide, formerly a family-owned company, can look back upon a success story of over 60 years that has maintained a leading market position, especially in the past years. With approximately 230 employees, the company generated sales revenues in 2007 of USD 64m.

The company, which is headquartered in Raleigh (North Carolina), is active worldwide and operates sales sites in the U.S., Asia, and Europe. Aeroglide supplies various thermal processes and produces specialized production systems. Aeroglide has established an international reputation especially in the drying of foods, feeds and of industrial products.

Aeroglide and Buhler have maintained a close business relationship for years. The drying systems of Aeroglide, which are based on belt conveyor technology, complete Buhler’s portfolio especially in the field of extrusion. The acquisition of this long-standing supplier creates the basis for joint development of optimally matched, complete industrial solutions.

The combination will open up new opportunities for customers of Buhler and Aeroglide alike. Buhler plans to maintain Aeroglide’s operations as an autonomous center of competence for thermal process and drying technology at the company’s existing site in Raleigh.

Buhler is a global leader in process engineering, especially production technologies for making foods and engineering materials. Buhler is present in over 140 countries and has some 6900 employees. In fiscal 2007, the Group generated sales of CHF 1770m.

Morphologi G3 Identifies Powder Batch Differences

Malvern, UK -- A new statistical data analysis tool for the Morphologi G3 high sensitivity particle characterization system from Malvern Instruments makes it quicker and easier to investigate batch-to-batch variation in a powder feed or product.

From the database of size and shape measurements generated by the Morphologi G3, the data comparison tool rapidly identifies the parameters responsible for batch-to-batch variation. The results, in combination with process or product performance data, make it easy to identify those parameters that are ‘critical to quality’ and set appropriate criteria for QC.

Widely applicable, this new tool is particularly relevant for the pharmaceutical industry, with its current focus on more effective specification setting, as encouraged by QbD.

The Morphologi G3 measures particle size and shape parameters for tens of thousands of particles in a sample in just minutes, generating significant quantities of information. The new comparison tool allows selected sets of data to be compared on the basis of any recorded variable. It produces a parameter variability bar chart that shows which properties vary most across the selected records, and has a dendrogram function that clusters sets that are similar in terms of any chosen parameter.

If certain batches are known to perform well then they can be manually clustered, as an input, prior to analysis. The software will identify the linking parameter that is similar for all successful batches, and the value of this variable that defines success. Alternatively an undirected investigation of six batches of material, for example, may reveal that circularity, a shape parameter, varies most between batches and that batches 1, 3, 4 and 6 are similar in terms of this parameter, while 2 and 5 are different from the rest but similar to each other.

An application note detailing use of the data comparison tool for the analysis of pharmaceutical excipients is available from Malvern's website.

Sweco Announces New ALPHA Air Classifier

Florence, KY -- Sweco announces the manufacturing availability of this robust turbo classifier from their recent acquisition of Ecutec S.L. headquartered in Barcelona, Spain. The purpose of these classifiers is to achieve the best yield at very low specific energy consumption while occupying narrow and difficult space conditions.

The ALPHA classifier was developed for the production of fine products from 150 microns down to 6 microns and is especially suited for dry powders, both mineral and chemical products. Depending on the fineness required, this equipment can be fed by gravity from the top or in the main airstream from below, and can be customized with either stainless steel, ceramic or polyurethane for wear protection and specific material requirements.

Please inquire at info@sweco.com regarding this new equipment that requires minimal maintenance and is also available with various options to meet a wide variety of air classification needs.

With more than 60 years of separation technology experience, Sweco serves the pharmaceutical, chemical, food, minerals, paper and many other industries with a complete line of separation, sizing and milling equipment.

Mr. Hale wants help with belt conveyors in cold climates:

Please can someone help? I am familiar with the maritime climate that we have in the UK and the associated problems with belt conveyors in that environment.

I have to write a spec for belt conveyors (carrying 0-50mm gypsum rock, max 10% free moisture) in Russia where the temperature range can be -30 to 30'C. I am have no experience with the really cold temperatures and the snowfall that would be associated with them.

Can anyone tell me what other issues could there be with belt conveyor operation in such climates?

Intuitively, I think there must be problems with ice build up on the head and tail drums causing tracking problems, freezing of rollers increasing drive load, freezing solid of the material while on the belt if stationary for a time...

Am I missing anything obvious?    (to post reply, click here)

Thanks in advance,

Mr. Kamali needs help preventing silo deformation:

I am working on a problem relevant to a flour silo which has been deformed probably because of bridge collapsing.

The silo has a breather valve 10" but it seems that its size is not sufficient to let the enough air entering to the silo when the bridge collapses.

I want to calculate the vacuum pressure resulting from falling of formed dome and determine the required inflow air.

I would be very thankful if anybody guide me.  (to post reply, click here)

Eliminating Wasted Production Effort

Material transfer is an integral part of any operation. When increased production demands and new product lines challenge a processing line, those charged with optimizing production must evaluate an array of factors when determining the best method for moving chemical ingredients. To eliminate wasted efforts in production, manufacturers are moving away from conventional methods...(more)
