Vacuum and blower systems are commonplace in food manufacturing facilities. Bakeries, flour mills, breweries, and dairy plants are just a few of the many sites where vacuum pumps and blowers are used. While these facilities may leverage both types of systems, vacuum pumps are more commonly used when processing meats, fish and poultry. Other common vacuum applications include maple sap extraction, confection, vacuum coating, and juice distillation.

Yeast fermentation is a vital process in the production of many food and beverage products. It is a common application within breweries, bakeries, and wineries, along with other facilities where biogas and ethanol are produced. In these facilities, fermentation tanks filled with a reaction liquid are often supplied with air from blowers. Recently, there has been a trend in the adoption of high-speed turbo blowers for yeast fermentation applications, as the blower technology can yield large energy savings if properly installed and controlled.

The Ilmajoki sewage treatment plant (STP) located in southern Finland was built in the mid-1970s during a boom of infrastructure construction. Over time, industrial presence in the Ilmajoki area grew, and the plant saw an increase in flow of industrial effluent—or liquid waste and sewage. As the amount of influent increased, the plant was no longer able to meet required performance criteria suffered from a severe lack of oxygen—particularly during peak loading times.

Within the “zero-loss” culture at General Mills, plant personnel identify and optimize major energy users in each facility. Common opportunities include: the optimization of dryers, ovens and freezers; compressed air optimization projects; improvements to building heating and cooling system; and lighting replacement innovations. In addition, engineers at General Mills have started to explore new energy-saving opportunities within the vacuum and blower systems at their production facilities. To better understand how any production system is addressed at General Mills, an examination of the company’s energy management methodology is required.

Industrial vacuum trucks, also known as industrial vacuum loaders, are used to recover, contain, and carry solids, dry bulk powders, liquids, slurries, and thick sludge from hard-to-reach areas. Guzzler Manufacturing, an industrial vacuum truck manufacturer based in Streator, Illinois, has long-standing expertise in pneumatic conveying—both dilute and dense phase—for all kinds of industrial applications.

Compressed air audits are valuable exercises on significant energy users in a plant.  Often done on main compressed air systems, these studies are also valuable on secondary systems, like dedicated low pressure circuits that feed production machinery.  An audit of such a system turned up some surprising results on a process that was initially thought to be very efficient.

Hoffman & Lamson has been manufacturing multi-stage centrifugal blowers for a long time. Lamson was founded in 1880, and Hoffman was established in 1905. Now a single entity under the Gardner Denver Nash Division, the company has some serious resources to complement its 100-plus years of blower expertise.

For the University of Cologne, the COPT.ZENTRUM is a central element of their technology transfer strategy from science to practice. Small- and middle-sized companies will benefit from the premises of the center, the technology, and the newest scientific findings in the field of organic electronics. Oerlikon Leybold Vacuum supplies the necessary vacuum technology.

Metallurgical High Vacuum Corporation (MHV) is proud to announce another milestone in their commitment to excellence: they were awarded certification attesting to establishment of their quality management system in conformance with the International Quality System Standard ISO 9000-2008, with a scope for Design and Manufacture of High Vacuum Mechanical Pumps and Rebuild of Mechanical Pumps.

With the energy used by water and wastewater treatment plants in the United States accounting for 35 percent of a typical local government’s energy budget, GE formally introduced its new ZeeLung* Membrane Aerated Biofilm Reactor (MABR) technology that is four times more energy efficient than existing aeration systems. Aeration for biological treatment is the largest energy consumer in a wastewater treatment plant, typically representing 60 percent of a facility’s power usage.
