July marks an exciting milestone for Stellar: our 30th anniversary. While we’ve celebrated plenty of remarkable moments over the past three decades, we know we’re not the only ones. Food processing has experienced several turning points of its own, signifying key changes that have molded food manufacturing as we know it today.

Listeria is a foodborne illness that can have dire consequences–sometimes, deadly. The bacteria is characteristically persistent, able to not only thrive for years, but within frozen storage and outside of the expected environments, such as meat processing plants. Are you sure you’re taking the proper measures to ensure listeria isn’t growing in your facility?
Did you tune in to our Food Engineering webinar last week? We discussed the changing refrigeration climate, including what you should know about revised compliance schedules, innovative refrigeration technologies and the pros and cons for each. You can check out our full presentation in the SlideShare provided below.

Due to its phaseout, an alphabet soup of replacement refrigerants has been developed to replace R-22 in existing chillers. However, most of these alternatives have drawbacks. Some replacements severely penalize the performance of the chiller, while others have significant glide—and all have higher global warming potential than ammonia. And though these refrigerants may not be on the Environmental Protection Agency’s (EPA) phaseout list yet, they have the potential to be. As new chillers rise to replace the old, ammonia is one refrigerant that has become an effective alternative.

The majority of industrial refrigeration systems in the U.S. are central-station ammonia systems—the backbone of the food and beverage industry. For over 100 years, these ammonia systems have dominated the industry because they not only have superior thermos-physical properties, but also because they’re environmentally friendly. Ammonia has a global warming potential (GWP) and ozone depletion potential (ODP) of zero.

Did you know CO2 has been used in mechanical systems since the 1800s? However, over time, the industry has gravitated away from CO2 toward lower pressure, synthetic refrigerants like Freon. But now that synthetic refrigerants are being phased out due to their negative environmental impacts, it’s time to take a renewed look at CO2 as a viable refrigerant alternative. Continue Reading “Why CO2 is a Viable Refrigerant Alternative”
The overwhelming majority of climate scientists not only believe in global warming, but believe human activity is to blame. Whether you personally believe this or not, government bodies do. Over the past 30 years, international and national regulatory agencies have responded with legislation that fosters a more sustainable planet. And the attempt to phase out harmful chemicals—including refrigerants—has been constant.

Refrigeration screw compressors use axial thrust load bearings—and they have a life expectancy that will begin to fail over time. At one time or another, all food processors and beverage manufacturers will be in the market for a refrigeration compressor rebuild or replacement. Because the compressor and its bearings will deteriorate over time, staying on top of its performance is crucial to avoiding a catastrophic failure. Here are three methods that can help gauge your compressor’s fitness.

Stellar is experiencing a major uptick in sanitary design projects, and we have a hunch as to why. The implementation of the Food Safety Modernization Act (FSMA) has many food and beverage companies taking a deeper look at their processing practices, their plant designs and the equipment that goes inside their facilities. As food recalls litter the headlines and impact the health of consumers, food safety continues to be a crucial area of focus. A sound food safety program begins on the plant floor, and it all starts with following sanitary design best practices.

Aside from producing high quality, safe products, what is one of the most important rules of food manufacturing? Do not short your customers. If a disaster puts your plant’s operations on pause, know your options for continuing production outside the walls of your facility. Co-packing, co-manufacturing and built-in redundancy are three solutions to keep your operations moving when your plant is down. Here are the key things to know about each.
