精酿啤酒酿造工艺

精酿啤酒酿造工艺
　精酿啤酒的酿造工艺流程如下:
①麦芽粉碎：通过麦芽粉碎机将麦芽颗粒粉碎成适当
            粗细的麦芽粉；
②麦芽的糖化过程
  此过程将麦芽的淀粉在酶的作用下转化为糖浆。
●麦芽糖化：麦芽粉投入糖化锅与水混合后，通过加

            热控温，将淀粉酶解为麦芽糖浆。
●麦汁过滤：在过滤槽内将上述糖化醪液进行过滤，

            分离出杂质，获得清亮麦汁；
●麦汁煮沸：在煮沸锅里将上述麦汁进行煮沸，凝固

            出多余的蛋白质，同时煮出酒花中的风
            味物质。
●麦汁旋流：在旋流槽中将煮沸的麦汁进行旋流，分

            离出热凝固物和酒花糟；
●麦汁冷却：通过板式换热器将旋流麦汁冷却到适合

            发酵的温度；
③啤酒的发酵过程
  此过程将麦芽糖浆在酵母菌的作用下转化为啤酒。
●啤酒发酵：在发酵罐内添加酵母菌，将冷却麦汁发

            酵为啤酒；
④啤酒的灌装：将成品啤酒灌到包装物中储存。

●啤酒灌装：通过小型的半自动灌装机，在CO2密闭和

           抽正空的条件下，将啤酒灌入包装物中。
           包装物有:玻璃瓶、PET瓶、不锈钢桶等。

 Craft Beer Brewing Process
Craft beer brewing process is as follows:
① Malt milling: the malt crushed by malt mill turn out suitable malt grist;
② Malt mashing process
In the procedure, the malt starch is changed into syrup under the action of the enzyme.
●Malt mashing : the grist is mixed with water in the mash kettle, by heating temperature control, the starch becomes into malt liquid syrup by enzymolysis.
●Wort filter: in the lauter tun, the above-mentioned wort is filtered to separate the impurities then obtain the clear wort;
●Wort boiling: the above-mentioned clear wort is boiled in the kettle, solidify the excess protein, and extract the hop’ essential elements.
● Wort swirl: The wort is boiled in the whirlpool separator then separate the hot trub and scrap hops;
● Wort cooling: through the plate heat exchanger, the hot wort is cooled to the temperature suitable for fermentation;
③ Beer fermentation process
In this process, malt syrup under the action of yeast turn to beer.
● Beer fermentation: put the yeast in the fermenting tank, the cooled wort is converted into beer;
④ Beer filling: filling the finished beer into the containers for storage.
● Beer Filling: through manual or semi-automatic filling machine, under the airtight conditions by CO2 , the beer is poured into containers. The containers include the glass bottles, PET bottles, and stainless steel barrels etc.
