| Popis: | 94 Beer brewing has been the most efficient in automation process for alcoholic manufacturing in modern years. The beer product aims at low market price with small amount of margin since the market is generalized; therefore, the economic concept must be considered in discreetness when designing a brewery. Production cost and process time shall be reduced in considerable quantities with effective flavor control and stability in order to attract the market for most profit. Since the market is intensively high with numerous competitors, so the product must depend on its excellent quality and flavor in order to occupy in the market. During beer brewing, the fermentation and maturation are both key factors for the success. The wort will ferment into beer and store for maturation thru elaborated biochemical process. The fermentation and maturation process take longer than 30 days, under the circumstance of conservative cost, the horizontal fermentation tank has been developed into vertical cylinder tank in recent years. The newly development obtains advantage of both less fermentation time and production compatibility. The new design has been widely performed for beer production and expanding its capacity due to the production demand. Although the vertical cylinder tank contain the advantages of less occupied space, simple yeast recovery, convenient automatic cleaning, and production compatibility. But there is no general standard for the ratio between diameter and height. Especially the vertical cylinder tank has been expanding its capacity by cogitating for the production. Some of the tank can even reach more than 600M3 concerning on the production cost. To ensure the consistence temperature inside fermentation tank from the heat of environment, yeast breathing, fermentation process, and beer cooling, the heat transfer efficiency characterized quality flavor and maturation. This research will be discussing about the ratio between height/diameter of vertical cylinder tank, stability, the physic after fermentation, and heat transfer process. By connecting these factors, we can analysis the height/diameter ratio efficiency for vertical cylinder tank during process to improve the system design. |
