Rectification type wort boiling system and boiling process thereof

Abstract

The invention relates to a rectification type wort boiling system. The rectification type wort boiling system comprises a pot body, a heat preservation shell arranged outside the pot body, a rectification tower, an injection pump, a variable frequency pump, a wort pump and an external heater, wherein the rectification tower is arranged at the top part of the pot body; the inlet of the variable frequency pump is connected with the bottom part of the pot body; the outlet of the variable frequency pump is connected with the material inlet of the rectification tower; the material outlet of the rectification tower communicates with the interior of the pot body; the bottom part of the pot body is simultaneously connected with the inlet of the wort pump; the outlet of the wort pump is connected to the material inlet of the external heater; the material outlet of the external heater is connected to the material inlet of the top part of the pot body; and the steam outlet of the injection pump is connected to the steam inlet of the external heater. The rectification type wort boiling system and the boiling process thereof provided by the invention have the following advantages: through a manner of combining the rectification tower and external heating, the boiling efficiency of wort is improved; traditional wort boiling is replaced; and the advantages of energy conservation, difficulty in coking, large heating area, good boiling effect and conservation of saccharification and cleaning water are achieved.

Description

Technical field [0001] The invention belongs to the technical field of wort boiling systems, and particularly relates to a rectification type wort boiling system and a boiling process thereof. Background technique [0002] The beer brewing process is roughly divided into two major steps, saccharification and fermentation. The saccharification process includes the crushing of malt. The malt and hot water are mixed into malt in the saccharification pot and saccharified at the process temperature. Under the action of enzymes, water-soluble substances such as sugar are dissolved in hot water to form wort. Then add the wort to the boiling pot, heat the wort and boil for a while. After boiling, the hot coagulum is separated from the wort in the swirling flow (cyclone precipitation), and finally the wort is cooled and oxygenated into the fermenter, and put into the yeast to start fermentation. [0003] The beer saccharification process requires a lot of energy, and the wort boiling stag...

Problems solved by technology

However, in the fine brewing industry, since the tube length of the internal heater is usually less than 1.5m, the above-mentioned invention needs a large flow rate of the pump in order to avoid coking, but greatly increases the energy consumption, and can only save a small amount of heating steam and Part of the cleaning water is not in line with the current industry development trend of energy saving and emission reduction.
