Rough Vac

Vacuum and protective gas both reduce the activity of oxygen-dependent microorganisms inside the packaging. This way, vacuum-packaged foodstuffs have a longer shelf life, even without preservatives. There are different types of vacuum packaging. When it comes to cheese, the type of vacuum packaging depends heavily on the specific type of cheese.

The IWF 2022 International Woodworking Fair was held August 23-26 at the Georgia World Congress Center in Atlanta, Georgia. This was the first global woodworking fair since 2018. The Show attracted announced the attendance of thousands of verified buyers of woodworking equipment.  IWF is the largest woodworking technology trade show in North America and is held every other year at the Georgia World Congress Center in Atlanta, GA. It is ranked among the largest trade shows in the world. 

The new solution also saves close to 90 percent of the annual maintenance costs. The side channel blowers required intensive repairs and were therefore a source of high costs. MINK MV claw vacuum pumps provide completely dry compression of intake air and thus work without operating fluids such as oil or water. This makes the vacuum pumps virtually maintenance-free. 

SupremeX, a Canadian based envelope and packaging manufacturer, with 11 facilities across six provinces, as well as five facilities in the United States, recently upgraded the vacuum system in their Winnipeg based plant. This article discusses the system before and after the changes, and the significant energy savings, plus improved system reliability that resulted. The company also captured a significant utility incentive to help with the cost of a new cutting-edge variable speed vacuum pump.

Vacuuming fresh food using chamber machines is often a daily activity in butcher shops, at fresh food counters for meat, sausage, and cheese products, as well as in the foodservice industry. All fresh foods contain more or less unbound water, which partially evaporates during vacuum packaging. This can influence the quality of the product. Furthermore, if the packaging machine is not permanently in operation, the packaging result may deteriorate, or the packaging process may take too long.

The basic function of vacuum degassing is to remove the vaporized gas and moisture from the extruded material. During the extrusion process, as raw materials melt under heat and pressure inside the extruder. The polymer chains and chemical compositions are going through changes, and a variety of gases are released.

More than 300 million tons of plastic is produced every year, and much of it ends up causing environmental problems. In response to these challenges, there are widespread global efforts to increase recycling capacity and innovate for more efficient and effective recycling solutions. Vacuum plays a critical role in achieving these improvements.

Nowadays, pneumatic suction conveying is an important technology for feeding bulk goods gently through piping systems to the various process steps. In the area of food processing, the pharmaceutical and chemical industry and for material feed in plastics processing, suction conveying is indispensable when powder or granular materials have to be transported. The proper choice of the vacuum generator essentially determines the operating costs of a pneumatic conveying system. 

By using state-of-the-art vacuum technology for degassing mineral water, it has been possible to save an average of 3,000 cubic meters of water per filling plant per year. The solution was to replace the existing liquid ring vacuum pumps with MINK claw vacuum pumps from Busch Vacuum Solutions.

We present a few case studies derived on real-world application examples, where various vacuum technologies may be suitable solutions. Each case is generalized enough that the knowledge is applicable across multiple specific applications.
