About Caloris Permeate Dryers
Caloris has extended our deep experience with whey evaporation and concentration to the drying of whey permeate. Spray dryers for whey permeate powder are a key investment for many dairy production facilities.
Enhanced Production for Whey Permeate
The process of spray drying whey permeate involves the production of free-flowing powder by removing water from a slurried feedstock. This is an energy intensive industrial process involving many complexities, but it allows for an extended shelf-life while reducing transportation costs for the removed water.
Whether for new applications or to improve, enhance or increase your current installation or process, the Caloris team of spray drying process engineers is ready to help you solve your existing operational challenges or to take you to the next level in your production. In addition to our experience delivering custom dryers for whey permeate, we also deliver specialized spray dryers for whey protein concentrate and whole sweet whey.
We’re ready to specify, engineer, design, fabricate, install and commission your complete new whey permeate spray dryer.
