This invention discloses a novel process for the wort boiling stage in beer
brewing, comprising the following steps: wort pretreatment and sealing before boiling,
atmospheric pressure initial boiling activation, micro-pressure heating to 110-120℃, timed addition of hops, membrane
evaporation circulation-assisted boiling,
aeration for uniform boiling and
temperature control, boiling endpoint control, and rapid
heat load reduction. This invention utilizes a conical boiling
vessel structure and membrane circulation technology to achieve stable micro-pressure boiling at 110-120℃, completely solving the problems of wort spreading and scorching under high temperatures in traditional equipment, and broadening the wort boiling
temperature control range. Membrane
evaporation increases the wort
evaporation area, and combined with the wort circulation
system, improves evaporation efficiency and shortens boiling time. Simultaneously, the
insulation layer reduces heat loss and
energy consumption. The
aeration device drives the wort to tumble evenly, and combined with the fluid characteristics of the conical vessel, the wort is heated comprehensively and evenly, ensuring thorough
protein coagulation and avoiding abnormal wort color caused by localized scorching.
