Do You Really Need to Upgrade Your PLC-5 Automation System?

Source: Rockwell Automation

Upgrading PLC-5 automation systems has been on the food and beverage industry’s radar for quite some time now. In fact, when I began working at Stellar 12 years ago, people were buzzing about Rockwell Automation moving the processor into retirement (“Silver Series” status). However, the PLC-5 1771 was such a widely popular system, Rockwell held back on pulling the trigger until recently. In August 2012, Rockwell revealed it would no longer support the PLC-5 processor anymore, including engineering replacement parts—big news, considering more than 80 percent of the marketplace owned these systems.

The One Mistake You’re Making With Your Compressor Logs

After working with compressors for nearly three decades, there’s one mistake I see people making time and time again when it comes to their compressor maintenance. They keep their daily logs, recording necessary temperatures regularly, but when they’re through, they simply put the logs aside and don’t look at them again. The results are not analyzed for corrective measures, if discovered. Are you looking back to ensure you’re addressing the inconsistencies and issues you notice during your compressor evaluations? Analyzing the daily logs is just as important as writing it down. Continue Reading “The One Mistake You’re Making With Your Compressor Logs”

14 Factors to Keep Your Refrigeration Compressor Package in Check

While we’ve already blogged about ways to determine the fitness of your refrigeration compressor, it’s important to pay attention to the big picture as well. Ensure you keep up with the the health of your entire refrigeration compressor package, as failure to check components including the motor, control panel and suction superheat, can cause major failures. Here are the 14 key factors to check within each component of your compressor package.

The Latest in Natural Refrigerants: ATMOsphere America 2015 Recap

I recently joined hundreds of refrigeration stakeholders in Atlanta for ATMOsphere America 2015, an annual natural refrigerants conference. Stellar was among the 37 sponsors, and I among the group of 60-plus speakers, leading a presentation on the advantages of packaged refrigeration equipment. I also attended several sessions myself, leaving the conference with valuable takeaways on the refrigeration industry, including my favorites below: Continue Reading “The Latest in Natural Refrigerants: ATMOsphere America 2015 Recap”

Is Your Food Processing Plant Safe From Listeria?

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?

3 Ways to Prevent Food Plant Electrical System Malfunctions

Do you give enough care and consideration to your food processing facility’s electrical equipment? As a senior electrical engineer for Stellar, I joined several of my peers in a discussion in this month’s Food Engineering article, “Electrical systems and components: The lifeblood of your facility,” on electrical safety, systems maintenance and more. In the article, I reviewed factors that impact your plant’s electrical well-being. Below I describe them in greater detail for Food for Thought’s readers: Continue Reading “3 Ways to Prevent Food Plant Electrical System Malfunctions”

Refrigeration for the Future: Low-Charge Refrigerated Packaged Equipment

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.
