The Wort Sterilization System (CWS) is used for the production of cold sterile beer wort. The beer wort is heated up to 110 °C to ensure absolute sterility. The temperature is kept for a specified time while the wort is flowing through the holding pipe. Then the wort is cooled down regeneratively and further cooled with glycol or ammonia.
The process is well established in the brewing industry for providing sterile beer wort for the reliable and continuous operation of the yeast propagation. The system is characterized by exact control of sterilization temperature, high operational reliability and high heat recuperation up to 95%.
