Continuous Wort Sterilization (CWS)Sterile wort is a fundamental requirement for yeast propagation. Typically, wort is heated in a propagation tank and then cooled again for this purpose. Since no heat recovery is possible in this batch process, the demand for heating and cooling energy is enormous. Through the continuous process in Wort Sterilization CWS, up to 96% of the heat can be recovered.
How does CWS work?The wort to be sterilized is first heated regeneratively and then with steam or hot water to the sterilization temperature. Flow and temperature are regulated depending on each other to maintain constant conditions according to the specifications. After passing through the hot-holding section, the wort is regenerated and optionally cooled with the help of a coolant.
The pressure increase pump between regeneration and heater ensures that the pressure in the sterilized product is always higher than in the non-sterilized product, preventing contamination in case of leakage. During plant shutdown, a controlled product discharge is carried out with degassed water using media separation based on volume or conductivity. When the plant goes back into production, the degassed water is pushed out with wort.
