Beer fermentation process

Craft beer fermentation process of beer fermentation process is beer yeast under certain conditions, using the fermentable wort sex material and normal life activities, its metabolic product is to the product - - - - - - - Beer. Because of the different types of yeast, fermentation condition and product requirements, different flavor, fermentation way is not the same. Different depending on the type of yeast fermentation is the beer into the fermentation of beer and the beer fermentation. Generally can be divided into the traditional fermentation technology of beer fermentation technology and modern fermentation technology. Modern fermentation mainly include outdoor conical cylinder fermentation, continuous fermentation and high concentration dilution fermentor, at present mainly adopts cylindrical open-air conical fermenter fermentation. Beer fermentation process flow diagram of the beer fermentation process production process: oxygenate cold wort & rarr; Fermentation & rarr; Before fermentation & rarr; The main fermentation & rarr; After fermentation & rarr; Wine storage & rarr; Fresh beer & uarr; Strain 1, malt crushing: malt before into production workshop, to be sent to the shattered tower first. Here, the malt by light pressure made brewing malt crushing. 2, gelatinization process: the crushing malt/grain mixed with water in the mash copper. Mash copper maneuver is a huge metal containers, filled with hot water and steam inlet, mixing device, such as stir bar, impeller or propeller, and plenty of temperature and control device. In the mash copper, malt and after heating the water boils, it is a natural acid will difficult soluble starch and protein into soluble malt extract, called & quot; Wort & quot; 。 Wort are then sent to the filtration container called separation tower. 3, saccharification: malt juice before is pumped into the boiling pot to make out of it in the filter tank malt leather case, and join the hop and sugar. 4, boiling: in a boiling pot, boil mixture is to absorb the flavor of the hop, and improvement and disinfection. 5, filtering: after boiling, add hop malt juice is pumped into the swirl sedimentation tank in place does not need to hop leftovers and insoluble proteins. 6, cooling, fermentation: clean the malt juice from the swirl of the sedimentation tank, pump out in to a heat exchanger to cool. After that, the yeast is added into the wort to begin to enter the fermentation process. In the process of fermentation, yeast cultured in wort fermentable sugar into alcohol and carbon dioxide, producing beer. Fermentation occurs in eight hours and to speed up the pace, the accumulation of a called & quot; Wrinkle spray & quot; The high density foam. The foam in 3 or 4 days to reach its highest stage. From the fifth day, fermentation speed slow down somewhat, wrinkled foam began to spread in wort surface, it must be left out. Yeast in fermentation after all material available for fermentation wort, began in a thick layer of sediment at the bottom of the container. With the temperature gradually reduce, in 8 ~ 10 days after fermentation was completely over. The whole process, require strict control of temperature and pressure. Beer, of course, the production process of different, lead to different fermentation time. Usually, the lager fermentation process need about 6 days, ale for about five days. For the most part after the fermentation, yeast sedimentation on the bottom of the tank. Winemakers are under this part of the yeast recycling up for a can use. After removal of yeast, beer fermentation tank after being pumped into nun products ( Or known as slaking tank) 。 Here, the rest of the yeast and insoluble protein precipitation down further, make the style of beer is gradually mature. Mature time vary with varieties of beer, usually in 7 ~ 21 days. After after fermentation and mature in the heart of the filter all of the rest of the beer yeast and insoluble protein filter, became to wine packaging. 7, packaging, finished product beer packing often bottled, canned and bottled in several forms. Plus the bottle shape, the different capacity, labels, neck sets, and differences in the cap and the diversification of the outer packing, thus constitutes a wide variety of beer products in your market. Bottled beer is the most popular forms of packaging, also has the most typical packaging process, the washing bottle, filling, sealing, wine sterilization, labeling and packing.
