Common System Issues Part 1 - Oil-Free Air Compressors Paired with Heatless Desiccant Dryers

By Tim Dugan, P.E. President, Compression Engineering Corporation

Many food processing plants are already using oil-free compressed air at a low-pressure dewpoint. This has required the use of two-stage oil-free screw air compressors, centrifugal air compressors and other technologies, as well as regenerative dryers of one type or another. The most common oil-free air compressor in industry is the two-stage “dry screw” machine and the most common regenerative dryer type is the heatless type. These are combined in many food processing, pharmaceutical, and high-tech plants.

Safety: Food-Compliant Pneumatics for Fully Aseptic Juice Filling Machine

By Aventics

Machines for filling milk or juice must often work around the clock. Given the critical importance of uptime, Elopak opted for Aventics food-compliant pneumatics when developing its E-PS120A - the first fully aseptic filling machine for gable top packaging. With an output of up to 12,000 cartons per hour, disruptions and downtime are not welcome with the aseptic filling machine.

Nitrogen Gas in the Food Process

By Jenny Palkowitsh, Trace Analytics

Gaseous nitrogen is used in a variety of systems and processes in the food manufacturing and packaging industries. Often regarded as the industry standard for non-chemical preservation, nitrogen is an inexpensive, readily available option. Suited for a variety of uses, Nitrogen needs to be monitored for purity and potential contaminants. Depending on the type of use, the distribution channel, and the required purity levels, different testing plans should be implemented to ensure safety.

Measuring Performance of Installed Air Compressors

By Thomas Fischer, SUTO iTEC

Measuring the Free Air Delivery (FAD) of an air compressor can be challenging. With a proper flow meter and some mathematics this task is manageable. This article sheds some light on how to select the flow meter and summarizes parameters to be considered in the FAD measurement task.

Nitrogen Generation in the Metal Industry

By Patrick Hyland, Technical Specialist, Valin Corporation

Factory lasers use nitrogen right at the cutting point on the metal because the high temperatures used in the process can often cause oxidation. When oxidation occurs, the metal pieces being cut can be damaged, as can the tooling creating the cut. Structural damage or inaccurate cuts can make parts weak and render them useless. The use of nitrogen at the point of contact from laser to metal removes oxygen from the cutting area and helps cool the die as it cuts, thus preventing oxidation. This prevention improves the quality of the final products, produces less scrap metal and cuts back on the reworking of pieces.

A Pulse Jet Dust Collector Optimization Study

By Russell Morine, Compressed Air Systems Evaluation Specialist, The Baker Group

A flour based frozen foods manufacturer orders a compressed air efficiency audit. The audit establishes the cost of compressed air at \$0.27/1000 cubic feet. The study finds the 116 pulse jet dust collectors represent the greatest opportunity for compressed air demand reduction and energy cost savings. A dust collector optimization study/service is suggested and the customer agrees to proceed. In this facility, pulse jet dust collectors are used to filter dust from raw materials entering the plant, for conveying and mixing of ingredients, and for the final packaged finished products leaving the plant.

Optimizing Today’s Pneumatic Systems

By Bill Nevills, Certified Fluid Power Specialist, Valin Corporation

In the last ten years, the design of pneumatic systems has changed dramatically, mainly due to developments in the technologies that create them. Pneumatic manufacturers’ online tools for sizing components have evolved, the fieldbus systems are ever-changing, component designs are constantly improving, and network devices such as the Industrial Internet of Things (IIoT) have reshaped the industry. All these advances play a large role in optimizing the efficiency of pneumatic systems, but the age-old practice of routine maintenance must not be overlooked. This article will focus on proper air compressor sizing, proper pneumatic component sizing and predictable preventative maintenance.
