Wort boiling process in beer production process

The invention discloses a wort boiling process in a beer production process, which comprises the following steps of: S1, putting filtered wort into a boiling pot, and cooking the wort to 98 +/-0.5 DEG C by using steam introduced from the upper layer and the lower layer of the boiling pot; s2, continuing to cook the wort by using steam, and blowing nitrogen into the boiling pot until all wort obtained after filtration enters the boiling pot; s3, stopping introducing the steam into the lower layer of the boiling pot, heating the wort to be boiled by utilizing the steam on the upper layer, and blowing nitrogen into the boiling pot; wherein when 80-90 m < 3 > of wheat juice is heated, the total use amount of steam is 3000-6500 kg, the total time for introducing steam is 80-90 min, and the total use amount of nitrogen is 35-130 kg. According to the wort boiling process in the beer production process, nitrogen is adopted to replace part of steam, and the use of the steam is reduced, so that the purpose of saving th
