Flow Pasteurizer
The Hermis flow pasteurizer was designed for constant thermal processing of beverages including juice, wine, beer, kvass, and other drinks. The machine starts by rapidly heating the liquid to a predetermined temperature. The liquid is then held for a while, and then it is cooled. This thermal process reduces the number of microorganisms in the product and as a result increases its shelf life.
