Krones VarioFlash B Flash Pasteurizer (2019)

Krones Kurzzeiterhitzung KZE

Overview

This Krones VarioFlash B is a flash pasteurization system for beer and beer mix beverages, built in 2019 by Krones AG at its Steinecker plant in Freising, Germany. It pasteurizes 20 - 45 hl/h in a three-stage plate heat exchanger with energy recovery, a heat retention tube and a cooling stage. Everything is mounted on a stainless steel skid with a horizontal 2,100 l buffer tank, and a freestanding stainless steel control cabinet with touchscreen HMI completes the system.
