Bright Beer Tank

What is Bright tank?

Bright Tank is a dish-bottomed pressure-rated temperature-controlled tank used to hold beer in preparation for packaging. The term “bright” refers to “bright beer,” beer that has been rendered bright (clear) by filtration, centrifugation, fining, and/or maturation. In most breweries, beer will be filtered after leaving a uni-tank or lagering vessel and be directed into a bright tank. If the beer is to be force-carbonated, then the beer may be carbonated in-line, under pressure, between the fermenter or lagering tank and the bright tank.

Bright tanks are also sometimes used as mixing tanks for beers that are to be bottle-conditioned. Here, the beer will be mixed with priming sugar and possibly with new yeast intended to carry out re-fermentation. The beer is then bottled (or, in rare instances, kegged) from the bright tank. In brewpubs, the bright tank is often also the serving tank; beer may run directly from this tank to the taps at the bar.

We fabricate our vessels to the highest level of craftsmanship and build quality that will compare favorably to anything on the professional brewing equipment market. All of our vessels are pressure tested, 100% sanitary welded, Pickling passivation, jacketed and insulated.

Production requirements:

1. Welding: We abandoned the argon gas cylinder but adopt The Central System of Argon to make sure the TIG welding with pure argon gas shield. We also increase the using amount of gas when welding, so the quality of the welding line is higher. 
2. Dimpling: We adopt a dimple plate rather than a belt for glycol jacket since it can increase the cooling area and improve the speed of cooling. The most important thing in the brewing process is to avoid contaminating, that is to say the most important thing in producing beer equipment is to polish the inside tanks to 0.4~0.6 μm without dead corner.
3. Polishing: We use large-scale polishing equipment to polish the inside of the tanks -- all over the wall to make sure there is no dead corner. You need not worry about there will be some bacterias remained after cleaning.
