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.

Four Compressed Air Demand Reduction Projects

By Don Van Ormer, Senior Auditor, APenergy

A large food manufacturing operation in the U.S. Midwest spends $529,000 annually on energy to operate the compressed air system.  The plant currently has two supply-side systems that operate and feed two different distribution networks at two different pressures. One compressed air system is at 115 psig (medium pressure system) and the low-pressure system is at 30 psig. The compressed air equipment for both systems is located in four areas throughout the facility.

Food Packaging OEMs, Vacuum and Air Quality at IPPE

By Roderick M. Smith, Editor, Compressed Air Best Practices® Magazine

We visited the 2024 International Production & Processing Expo (IPPE) with the objective being to discuss hygienic vacuum and compressed air system designs within thermoforming and other meat/poultry/cheese packaging systems. We were able to discuss the sanitary designs they deploy and some protective measures they have in place, should the manufacturing plant provide compressed air which is not clean and dry and therefore conducive to hygienic manufacturing.

Defining the Purity of Facility Generated Nitrogen Gas

By the Compressed Air & Gas Institute

While oxygen is unquestionably the most important gas in our atmosphere, as it is essential for most animals and human life, nitrogen is the most widely used atmospheric gas.  Nitrogen is the go-to gas for countless industrial, medical, and scientific applications. This is because nitrogen is in vast supply, inert, and possesses the desirable characteristics of being colorless, odorless, and tasteless. The purity of nitrogen significantly affects the outcome of the application for which it is used and how the industry measures the purity of nitrogen gas is the focus of this article.

Growing Dairy Product Processor Improves Uptime with Compressed Air Audit

By Don Van Ormer, Senior Auditor, APenergy

There were two situations brought to our attention. The first was that production at times was having to slow down, or even stop, due to compressed air system pressure falling below the required levels. The second reason was due to reports, from plant personnel, of compressed air moisture problems negatively affecting the bag life of the dryer baghouses.

Compressed Air System Optimized at Cheese Packaging Plant

By Hank Van Ormer, Technical Director, APenergy

This assessment identifies a path to reduce the energy consumption from \$85,000 to \$51,000 per year. This can be done with little capital by fixing poppet-valve control problems on the air compressors and reducing flow and pressure requirements. Due to article space limitations, this article does not provide detail on the flow reduction projects. It focuses only on the impact these projects have on the air compressors and provides readers with a template on the information they should have on their units, by shift.
