Industrial Utility Efficiency

Vacuum Systems

Vacuum can be used in many ways for the meat processing and packaging industry. From mixing ingredients to evisceration (removing organs, excess fat, bones, etc.), to the washing/preparation of the meats or even in the packaging of the meat itself, vacuum is critical to the industry. 

Engineered Vacuum Solution Saves Oregon Brewer 5,000 Gallons of Water Per Day

When Craft Brew Alliance (CBA) set a goal to dramatically reduce water consumption at its Widmer Brothers Brewery in Portland, Oregon, it focused its efforts on its bottling process – and implemented a solution engineered by Atlas Copco that saves 5,000 gallons of water per day. In addition, it saves the craft brewer $39,000 per year, thanks to the elimination of water treatment costs and reduced energy use.

Central Vacuum Supply for Efficient Cheese Packaging

DMK Deutsches Milchkontor GmbH produces sliced cheese and Mozzarella at its production facility in Georgsmarienhütte, Germany. The various types of sliced cheese and Mozzarella blocks are vacuum packed after processing in several packaging lines. The vacuum supply for the packaging machines is provided by a Busch centralized vacuum system, which supplies both the packaging lines and the thermoforming machines.

Less Maintenance Thanks to the Centralization of the Vacuum Supply

Choosing the right vacuum supply can lead to huge cost savings in plastics processing. Mar-Bal, Incorporated has undertaken a critical review of the existing vacuum supply for injection molding when moving to a new plant and has collaborated with Busch, LLC to find a solution that will achieve savings in energy, maintenance and production times.

Reducing Demand in Industrial Vacuum Systems

This article will focus on optimizing the demand-side so the centralized “supply-side” (the vacuum pumps and controls) can then run at a lower energy and maintenance cost. First, I will start with a simplified model of a vacuum pump system demands. See Figure 1 for a one-pump/one-demand simplified system. See Figures 2-6 for some typical controlled and uncontrolled demands. The symbol with the three lines is an orifice, a hole essentially. I am defining three types of system demands adding up to the total demand on the vacuum pump.

Suttero Bazenheid Advances Meat Processing to Energy-Efficient Centralized Vacuum System

Energy for the entire Ernst Sutter AG company – and consequently the Suttero Bazenheid premises as well – is generated via hydropower. In addition, around 75% of the energy from refrigeration is also used to generate hot water. When creating vacuum for packaging, Suttero Bazenheid relies on a centralized vacuum system from Busch. This is significantly more energy-efficient in operation than decentralized vacuum supplies on individual packaging machines. As a result, Ernst Sutter AG has created a production plant that corresponds to the latest standards, both from a technical and ecological perspective. 

Rotary Screw Vacuum Pumps Benefit Meat Packaging Plants

Meat packaging plants have long used vacuum pumps as a way to remove air and reduce the amount of oxygen in their products’ plastic packaging. Vacuum packaging extends the meat’s shelf life while protecting its flavor and exposure to outside elements, such as freezer burn and bacteria.

Modern Woodcrafts Automates with Robotic Arms and Intelligent VSD Vacuum Pumps

The integrated process that leads to perfectly finished components begins in the plant’s new material store. “One way we’re staying at the leading edge in our market is by researching the latest innovations and choosing the best machine for each process,” Legere explains. “Our new material store, operational in June 2017, is one example. It combines a physical data base of sheet goods with a robotic arm that handles materials and presents them to a cutting machine for processing. After a few minutes, a finished part emerges. All of this occurs with zero human interaction.”

Vacuum System Fundamentals for "Compressed Air People"

If you want to understand vacuum systems, you have to get out of the ruts, and slog through the mud and bounce over the rocks a bit.  If you’re a “compressed air person”, think outside the box for a few pages with me.  I am going to borrow some terms from the “pump people” to explain how vacuum systems are similar, yet different from compressed air systems. There are several ruts to get out of.  Remembering what changes and what doesn’t, what is controlled, and how to design systems for optimal energy consumption.

Optimizing Five Liquid Ring Vacuum Pumps on a Paper Machine

Industrial process operating loads and optimal set points are not usually accurately known at the time of design, so often there is significant mismatch between equipment and the process it serves. To overcome this uncertainty, designers typically oversize equipment. Over time, process changes and equipment efficiencies decline, so equipment might be operating less efficiently than at start-up. Or, equipment can be undersized, thereby hampering the entire system and causing other inefficiencies to compensate. For instance, too much steam usage in the dryer section of a paper machine can occur because of inadequate vacuum at the wet end.

Cabinet Manufacturer’s CNC Routing Tables Switch to a Centralized Vacuum System

Multiple vacuum pumps can be running mostly “dead-headed” in the many production systems that don’t require constant flow.  Any system that evacuates a small volume and then holds a product down while it is being machined, or sucks a bag shut to seal will spend the majority of its time not moving much mass of air.  This type of operation is found everywhere in secondary wood processing, machining, food packaging, and many other industries.  Anywhere vacuum is used as a motive force or to evacuate a small volume repeatedly.  This article will apply to any of these types of systems- and not apply to constant-flow vacuum applications in the process industries.
