Leybold: Hygienic Enclosures for vacuum pumps ensure highest hygiene standards
Picture: Leybold

For consumers and the government, a maximum of safety and quality in the production of food is essential. In order to ensure the highest standards of hygiene, food producers and processors are obliged to clean their machinery regularly via washdowns. To guarantee that vacuum pumps are effectively protected from the used aggressive cleaning media, Leybold has developed a series of Hygienic Enclosures. The vacuum specialist offers users these stainless steel housings in seven different sizes, tailor made for each vacuum pump.

Risk of contamination eliminated

In the food industry, vacuum pumps are often placed directly next to the processing and packaging lines and thus not implemented in the equipment. On the one hand, this leads to a higher vacuum performance because, losses in pumping speed over longer pipelines are avoided. A direct positive consequence of this, are shorter process cycles and a better product quality. On the other hand, unprotected pumps are directly exposed to aggressive cleaning media during the rinsing processes. Over time, this leads to corroded vacuum pumps, shorter life cycles, higher costs and ultimately even to food contamination.

Effectively protected in stainless steel enclosures

In order to counteract these risks, Leybold has developed a new protection concept with the Hygienic Enclosures. Encased by these stainless steel enclosures, the vacuum pumps can be positioned near machines and systems without any problems. „On the basis of the protected Leybold vacuum pumps we can create better and more robust solutions for the demanding food applications“, emphasizes the responsible product manager Niels Gorrebeeck. „Of course, this applies all the more to applications such as stuffers, tumblers and of course packaging machines, where the machines and systems are cleaned and disinfected particularly frequently and intensively,“ the product manager explains.

Tailor made & easy to install

Gorrebeeck explains that these stainless steel enclosures are tailor made for each vacuum pump. As a result each enclosed pump can run constantly on every working pressure. The only limitation is the maximal ambient temperature for the enclosure. Nevertheless, the normal working temperature in F&P environments are around 10 °C, we qualified most enclosures up to 25 °C. Further all the enclosures are offered as a Do It Yourself kit and can be as well installed as commissioned by the user themselves without great effort. „These properties make of the Hygienic Enclosures a cost-effective, sustainable solution. In the end, Hygienic Enclosures makes investments in expensive piping obsolete and at the same moment they offer a better pumping speed performance“, argues Niels Gorrebeeck.

Sustainable solution

Incidentally, this also applies not least with regard to future packaging concepts. Gorrebeeck believes that the industry is also well equipped for this with the new enclosures: „Regardless of which solutions will prevail, food applications can be operated from today more hygienically, ergonomically as well as flexibly. Leybold can successfully accompany these processes into the future with our holistic solution approaches.“

Certification for Eppendorf ULT freezers

As further step into the green future, My Green Lab, a global non-profit organization promoting sustainability in the Life Science Industry through Green Lab Certification and validation of sustainable and energy efficient equipment has certified several Eppendorf ULT freezers (-80°C) to ACT, the Environmental Impact Factor label.

The Eppendorf ULT freezers are the first freezers worldwide being validated by My Green Lab:

The CryoCube® F570h, CryoCube FC660h, CryoCube F740hi, and CryoCube F740hiw are now validated and certified based on the ACT label in the US, UK and EU market. The holistic scoring evaluates a number of environmental factors across the lifecycle of an instrument. Power consumption is based on external testing at ENERGY STAR® with US-voltages. These ULT freezers are also certified by the ENERGY STAR regarding their sustainability footprint.

Flottweg Industrial Centrifuges for Wheat Starch Extraction

Tricanters, Decanters and Sedicanters optimize Viresol’s process in wheat processing.

One of Viresol’s main concerns was to reduce the company’s ecological footprint. Above all, it was about using less energy and water. Flottweg supplies the right overall package for this: two Tricanters, four decanters, two Sedicanters and the right equipment. These include dough mixers, curved sieves, pipes and the static design of the hall. This enables various products such as starch, gluten, maltodextrin, feed and ethanol to be produced in an energy-efficient manner. Flottweg industrial centrifuges also reduced water consumption.
