Grebbestad Brewery upgraded to ozone sanitation
Introduction.
No chemicals and a safer working environment
Grebbestad is not just a favorite among domestic and international tourists, it’s also Sweden’s oldest microbrewery. The facility brews several popular beers such as India Pale Lager, Saison and the Swedish classic Christmas holiday drink julmust.
The brewery, located on the beautiful Swedish west coast, has been using traditional acid and hot water to sanitize the fermentation tanks, filling machines and other process equipment.
They have now upgraded their sanitation routines with an Ozonetech ozone system, resulting in tangible operational benefits and a more gentle environmental footprint.
The problem.
Ever since the start in 1995, Grebbestad Brewery has used large amounts of chemicals and hot water to sanitize all process equipment – a necessary procedure to maintain the highest possible product quality and prevent product spoilage. It is one of the most water-intensive and costly operations during production along with chemical handling issues. The excellent sanitation potential of ozone presented an attractive solution for the facility.
The solution.
Together with Mellifiq, the brewery installed an Ozonetech high-performance ozone system which provides effective sanitation and disinfection of frequent clean-in-place operations. Ozonetech’s RENA Vivo system enables a turn-key sanitation solution in lieu of acid and hot water which has been used since the start.
An intuitive touchscreen, controlling the amount of ozone concentration during disinfection, enables on-demand sanitation and leaves no chemical residues. No more handling and administration of hot water or hazardous chemicals.
Evaluation.
The new Ozonetech RENA Vivo A-series high-performance ozone system has significantly reduced handling of and associated costs for disinfection chemicals. Water savings have also been realized since chemical residues have been eliminated. Sanitation time has been reduced thanks to the high disinfection capacity of the system. Thanks to Mellifiq, the brewery now runs more efficiently and chemical-free.
