COLD SANITATION OF CHEESE Brine by MicroFiltration (MF)
COLDSAN™
Dumping of cheese brine is normally very costly, and in some countries it is even prohibited due to the high salt content of the brine. Purification and recycling of the brine is therefore preferable and can provide advantages such as reduced operating costs and improved cheese quality.
Cheese brine, if not treated properly, can contain large amounts of undesired microorganisms, such as gas-producing lactobacilli, pigment-producing micrococcus, pathogenic bacteria, yeast and mold, which all affect the final cheese quality.
Unlike traditional brine treatment methods such as heat treatment, kieselguhr filtration or the addition of preservatives, microfiltration physically removes the undesired microorganisms, dead cells and physical contaminants from the brine without causing any significant change to its chemical composition.
GEA COLDSAN® has the following key advantages:
Larger brine pool volumes and fully automated units can be engineered individually to meet the required specifications.
The COLDSAN® unit can either extract a stream from the brine pool, cool it and send it back to the pool via a microfiltration unit. Therefore, the impurities are constantly removed resulting in higher purity of the brine pool. Alternatively, the feed can be returned to a separate pool exclusively for the clarified brine.

GEA custom designs membrane filtration systems that best utilize the technologies of microfiltration, ultrafiltration, nanofiltration, or reverse osmosis for each customer's specific application.
Condensate from evaporation plants is used as boiler feed water, process, cooling, and rinsing water or is directly discharged into a drainage ditch.
For this purpose, the condensate must be purified. Impurities in the condensate can be removed by membrane filtration, in the particular case by reverse osmosis, and high condensate qualities can ...
It is now possible to recover more than 90 percent of a spent caustic solution by using pH-resistant nanofiltration (NF) membranes. Benefits include reduced operating costs and better performance.
The GEA MICRO FORMULA® uses a special combination of standard flow components and plate heat exchangers to generate microparticulated whey protein concentrates (WPC) with precisely defined particle sizes and functional characteristics. These microparticulated WPC can be used to replace fat or milk protein in many dairy and food applications.
Healthy and happy cows are the key to successful and sustainable milk production. Keeping their cows healthy, therefore, is at the heart of every dairy farmer’s effort. Many factors influence the well-being of a cow, such as...
Industries across the board are working hard to meet net-zero targets while navigating stringent decarbonization regulations and legislation. At the same time, companies must balance growing demands for quality, product development...
Coffee, cocoa, milk, meat, fish and eggs – these daily staples rely heavily on intensive agriculture. With the rise of new food technologies, we have more sustainable alternatives. We sat down with Dr. Reimar Gutte, Senior Vice...
