1. The application of advanced in-body boiling and pressurization technology improves boiling strength, greatly increases the evaporation effect of dimethyl sulfide, promotes the polymerization of protein and other condensable substances, and realizes rapid separation of wort boiling and polymer. 2. The extracorporeal circulation mixing technology is adopted to accelerate the heating rate of the wort at the initial stage of boiling, so that the wort always maintains a uniform temperature during the heating process, and prevents the regional wort soluble denaturation caused by local overheating, thereby ensuring the wort Boiling quality.
