The increasing shortage of water combined with an ongoing debate about CO2 emissions are among the major challenges for the brewing industry in future.
A main contributor to water and energy consumption in the brewing process is the tunnel pasteurizer. To replace tunnel pasteurizers, membrane filtration or a flash pasteurizer can be used instead. Both technologies allow significant water and energy reductions, but increase the risk of late contamination of product at filling.
With a dedicated hygiene concept, starting from the Bright Beer Tank till the Packaged Product, this risk can be reduced significantly. Key aspects are:
– to choose a technology which ensures a safe and reliable separation of any beer spoiling microorganisms, including the opportunity for integrity testing and product traceability upstream of filling;
– to apply a certain standard for cleaning and hygiene work in packaging;
– to control contamination in the final product and during the process with a sensitive and fast detection method.
The paper describes the biological safety and economic achievements with membrane filtration, shows saving potentials for beer loss, water and CO2 emissions compared to a tunnel pasteurizer, gives an overview on cleaning and disinfection guidelines in packaging, and finally presents modern standards in PCR for rapid microbiological testing. All topics together present a complete solution for tunnel pasteurizer replacement without increasing risk for the packaged product.
