Problems solved by technology

[0002] Beer is the oldest alcoholic beverage for human beings. It is a low-alcohol wine full of carbon dioxide brewed by yeast fermentation with barley malt, hops and water as the main raw materials. It is the third most consumed in the world after water and tea. Beverages, however, the production of beer is accompanied by the generation of sewage, waste, etc., which has caused serious environmental pollution. The current beer production process has few pollution control measures. The application number is CN201210366762.4, which discloses a chocolate-flavored beer The production process includes the preparation of chocolate malt, the saccharification of chocolate malt and wheat, the boiling of wort, the addition of syrup and hops, and the fermentation of beer. The present invention does not add cocoa powder in the production process, and the produced beer not only emits the flavor of chocolate Attractive taste, low cost and the energy of beer is the same as ordinary beer; but there are no measures to reduce or control pollution, which seriously pollutes the environment and is not conducive to the sustainable production of subsequent beer

Embodiment 1

[0019] A kind of beer production technology of the present embodiment is characterized in that its processing steps are as follows:

[0020] (1) Raw material pretreatment: after soaking, germinating, drying and removing roots, the barley is sent to the crushing tower for crushing;

[0021] (2) Gelatinization and filtration: Heat and boil the crushed barley and water in the gelatinization pot to convert into soluble malt extract, that is, wort, and then send it to the separation tower for filtration;

[0022] (3) Sewage treatment: After gelatinization and filtration, the sewage from the washing gelatinization pot and separation tower is concentrated in the sewage pool through pipelines, and then processed by UASB+CASS, and the obtained water is used for industry and agriculture;

[0023] (4) Boiling: Boil the wort obtained in step (2), add water, add hops once for 10 minutes, 30 minutes and 10 minutes before the end of boiling. Its mass ratio is 70%: 30%;

[0024] (5) Precipi...

Embodiment 2

[0028] The rest are the same as in Example 1, except that the temperature in step (6) is controlled at 10°C, the fermentation time is 9 days, the time in step (7) is controlled at 15 days, and in step (2), the A paddle-type agitator is arranged at the bottom of the gelatinization pot, and the hops in step (4) are bitter granular hops and aroma and granular hops, and the mass ratio thereof is 65%:35%.

Embodiment 3

[0030] The rest are the same as in Example 1, except that the temperature in step (6) is controlled at 15°C, the fermentation time is 8 days, and the time in step (7) is controlled at 21 days. In step (6), the Saccharomyces cerevisiae is the bottom yeast, and the hops in the step (4) are bitter granular hops and aroma and granular hops, the mass ratio of which is 80%:20%.

[0031]

[0032]

[0033] Through the above three examples, there are three sets of data in the above table. It can be seen that when the fermentation temperature is controlled at 7°C and the fermentation time is 10 days, the amount of by-products of fermentation is the least, the taste is good, and the hops are bitter granular hops and aroma and Granular hops, its mass ratio is 70%: 30%, when the maturation time is controlled at 15 days, the beer is fragrant and mellow, and the visual effect is better, so embodiment 2 is the best embodiment.

[0034] The present invention completes the production of bee...

Abstract

The invention discloses a beer production technology which is characterized in that the technology comprises the following processing steps: (1) raw material pretreatment; (2) gelatinization and filtration; (3) sewage treatment: after gelatinization and filtration, sewage for washing a rice-cooker and a knockout tower is collected through pipelines into a sewage tank and then undergoes UASB+CASS treatment process, and the water obtained is used in industry and agriculture; (4) boiling; (5) sedimentation and cooling; (6) fermentation: beer yeast is added into wort and the mixture is fermented in a fermentor, temperature is controlled to 7-15 DEG C, fermentation time is 8-10 days, and then storage is carried out for about 6 days after fermentation; and (7) ripening and filtration. During the beer production process, a lot of sewage is produced, and sewage for washing equipment after gelatinization and filtration is the main source of sewage. Degree of pollution is high. By the beer production technology provided by the invention, pollution caused by washing sewage is treated, influence of beer production on the environment is reduced, and treated water is fully utilized to realize reuse of water.
