Maple Leaf Foods Saves with Compressed Air and Heat Recovery Upgrade

By Troy Dreier, Senior Editor, Compressed Air & Cooling Best Practices Magazine

One existing air compressor was a rental and not fully integrated into our compressed air system. We upgraded the desiccant compressed air dryer to improve operational efficiency, reduce energy consumption and save on the combined cfm. We save close to 900,000 kWh of electricity, and about 704 cfm every weekday.

Comparison of the Compressed Air Microbial Testing Unit to a Standard Method of Bioaerosol Sampling

By Lynne Landsborough Ph.D.

Compressed air is used in a number of processes in the food industry. It is used as an ingredient in whipped products such as ice cream, to slice or cut soft products and to open packages before filling of product. Currently, food manufacturers are under pressure to validate the safety of all ingredients or processes for regulatory compliance, but unfortunately, there is currently no standard method to evaluate the microbial content of compressed air.

Cornstarch Processor Saves $123,000 in Energy Costs

By Hank van Ormer, Air Power USA

This is a corn mill processing cornstarch, sugar, and other byproducts. Ambient air is contaminated with extremely high levels of dust due to the manufacturing processes and material handling. Average electric rates at the plant are \$0.04 / kWh. The actual plant electric cost for compressed air production is \$553,630 per year.

Meat Processing Plant Eliminates 1000 SCFM of Compressed Air Flow

By Don van Ormer, Air Power USA

This food & beverage plant is a large (500,000 sq ft) meat processing plant with twenty packaging lines and nine palletizers. The compressed air system is supplied from three separate rooms with seven individual lubricant-cooled, single and two-stage rotary screw compressors. The plant has four blower purge desiccant dryers designed to deliver a - 40°F pressure dewpoint.

Compressed Air System Design Recommendations for Food Processors

By Roderick Smith, Compressed Air Best Practices® Magazine

It was the Fall of 1997 in Germany. I was just another guy working in the German compressed air industry. East Germans were still being looked down on - seven years after unification, the Euro was launching in little over a year - forcing marketing managers like me to scramble and create unified european Euro pricing strategies, European Cohesion Funds were flowing out of Germany and into the Mediterranean (not literally), and the diminutive Mercedes “Smart Car” was the cool car for space-challenged urban dwellers. With this going on, you can imagine the surprise of the compressed air industry when compressed air was featured in “Der Spiegel”, a “Newsweek-like” weekly magazine in Germany with national distribution.

Reviewing Compressed Air Demand at a Food Processor

By James G. McAuley P.E.

This article reviews portions of an audit report of a compressed air system in a food industry factory located in the U.S. Although the audit explored different supply-side options the client should consider to improve dynamic efficiency, we will focus on the demand side of the system for this article.

5 Compressed Air Demand-Reduction Projects at the Brewery

By Don van Ormer, Air Power USA

This brewery is a relatively large operation with nine production lines plus a keg line. There are five bottle lines and four can lines. Operations in the plant include palletizing de-palletizing, filling, packaging operations, and brewing. Annual plant electric costs for compressed air production, as operating today, are \$693,161 per year.  If the electric costs of \$43,016 per year associated with operating ancillary equipment such as the blower purge dryers are included, the total electric costs for operating the air system are \$736,177 per year.  These estimates are based upon a blended electric rate of \$0.06 /kWh.

Improve Pneumatic Performance Through Filtration System Design

By Scott Minato, Marketing Manager – Air Preparation Products, and Barbara Pontisso, Filtration Products Specialist, Numatics, Inc.

In an ideal world, industrial air or gas supply lines would be free of particulate, water, oil and other contaminants. In the real world, however, supply lines typically deliver some contaminants along with the air or gas they were designed to carry. Left unchecked, these contaminants will cause efficiency losses, maintenance headaches and the premature failure of pneumatic components.

Meat Packager Reduces Compressed Air Demand

By Don van Ormer, Air Power USA

This meat processing and packaging factory spent an estimated \$203,640 annually on energy to operate the compressed air system at their Midwestern facility. Based on the air system operating 8,760 hours per year, the group of projects recommended below could reduce these energy costs by an estimated \$107,522 or 47% of current use. In addition, these projects will decrease compressor maintenance costs. Estimated costs for completing the recommended projects total \$21,900. This figure represents a simple payback period of 2 months.

Handling Corrugated Cardboard with Optimized Pressure-Regulation of Air-Driven Vacuum Pumps

By Josef Karbassi, Division Manager Automation, PIAB AB

Using suction cups and air-driven vacuum pumps is a preferable gripping and handling method of corrugated cardboard materials and boxes in carton-machines like case/carton erectors and rotary cartoners. Robot based applications, like palletizing and de-palletizing, are other examples where the best practice technology for gripping and handling is by suction cups and air-driven vacuum pumps.
