While not intuitively obvious, some processes lend themselves to having their control systems linked to a building’s control system, climate controls or HVAC. For example, a spiral freezer should be linked with process and environmental controls to save energy and improve the process. Other process applications that can benefit from further integration with environmental controls include drying, baking and other yeast-based processes.
Moving from an all-analog means of keeping track of process and storage temperatures can provide numerous benefits—for example, getting more robust measurements with higher stability, reliability and accuracy. In addition, you get better diagnostic information from the sensors themselves, and this information—coupled with temperature and other process variables—can help you get a better grip on your process and on maintenance, too.
Downey Ridge Environmental Co., developer of Greasezilla, has come up with a FOG separation system that can be implemented at food plants. I asked Ron Crosier, president of Downey Ridge, to fill us in on who might use Greasezilla and how it works.
Temperature is that one measurement that’s dictated by governmental regulations to prove that you have a kill step in your process. Beyond that, there are rules for keeping fresh food under a certain temperature to keep it safe both in transit and storage, and—just as important—maintain its quality so you don’t have to throw it out prematurely.
Consumers expect their food to be safe, and there are methodologies to ensure that it is. Quality is a bit of a different story, but it's just as important when it comes to consumer expectations.
Guarding against food fraud in the supply chain can be a costly, resource-intensive effort—but the potential effects of not catching it can be disastrous.
No question about it, sugar plants consume vast amounts of electricity, and with a lot of aging equipment, there’s no doubt that several motors and the mechanical systems they drive are probably consuming more power than they should—due to worn bearings and a general lack of maintenance. In many instances, motors are probably not using variable speed drives, and large inrush currents place a big demand on electrical utilities.
It also affords processors the ability to experiment with changes in batches or creating entirely new products, often with simply re-configuring lines.
Today, consumers expect to choose from a wide choice of brands and products—not just from the “center” of the store, but fresh and organic products from the periphery of the store. Sometimes new products are short lived and are designed to be that way—because consumers’ choices turn on a dime. Automation can help processors turn products around faster by increasing production.
In the engineering world, it has often been said that you can’t inspect quality into a product. Rather, you design and build quality into a product and then inspect to make sure you are delivering what you promise.
