What is the production process of beer?

Beer production can be roughly divided into three main processes: malt manufacturing, beer brewing and beer filling.

1, malt manufacturing:

Gelatinization treatment: mixing malt/grain to be crushed with water in a gelatinization pot. In the gelatinization pot, malt and water are heated and boiled, and then wort is sent to a filter container called a separation tower. Before the wort is pumped into the boiling pot, the hull of the wort should be removed in the filter tank and hops and sugar should be added.

2, beer brewing:

Saccharification: the crushed malt and starch auxiliary materials are mixed with warm water in the gelatinization pot and saccharification pot respectively, and the temperature is adjusted. After the fully liquefied mash in the gelatinization pot is put into the saccharification pot, the suitable saccharification temperature (62 ~ 70℃) is maintained to make malt mash.

Fermentation: Most of the yeast is deposited at the bottom of the pond. After removing the yeast, the product "tender beer" was pumped into the post-fermentor. Here, the remaining yeast and insoluble protein are further precipitated, which makes the style of beer mature gradually. The ripening time varies with beer varieties, and is usually 7~2 1 day.

3, beer filling:

There are several packaging forms: bottled, canned and barreled. Coupled with the different shapes and capacities of bottles, the different labels, neck caps and bottle caps, and the diversification of outer packaging, a wide variety of beer products have been formed in the market.

Drinking "three don't eat"

1, do not eat durian

Durian contains sulfur compounds, which can or can reduce the activity of acetaldehyde dehydrogenase by more than 70%, that is to say, it is impossible to completely metabolize alcohol into acetic acid that is harmless to human body. Durian can inhibit the production of acetaldehyde dehydrogenase. Eating durian and drinking will make people more likely to get drunk and even cause alcoholism.

2. Don't eat seafood

"Seafood is wine, just leave." Seafood contains a lot of purinol, which can stimulate acute gout. Alcohol has the function of promoting blood circulation, which will increase the chance of gout. Therefore, you can't eat seafood when drinking.

3. Don't eat bean jelly

Bean jelly is also a dish that most people like. However, a proper amount of alum should be added during the processing, which can slow down gastrointestinal peristalsis. Adding bean jelly to wine will prolong the pause time of alcohol in gastrointestinal tract, thus increasing the human body's takeover of alcohol, increasing the comfort of alcohol to gastrointestinal tract, slowing down the blood flow, prolonging the pause time of alcohol in blood, prompting people to get drunk and poisoning their health.
