Using vacuum or protective gases to package fresh food is currently the most commonly used method for hygienically packaging food and keeping it fresh for as long as possible. By removing as much oxygen as feasible, the vacuum reduces microorganism activity in and on the food so that it lasts longer, even without preservatives. Selecting the right vacuum generator has a significant influence on the packaging result, the operational safety, and the economic efficiency of the packaging process. If a plant uses multiple packaging machines that require vacuum to package foodstuffs, it may be worth considering centralizing the vacuum supply. A central vacuum supply can save a large amount of the operating costs and generate additional benefits, which we have summed up here.
Benefit 1: Energy saving
Central vacuum systems generally need fewer vacuum pumps than a decentralized vacuum supply connected directly to the individual packaging machines. This results in a corresponding reduction in energy consumption.
