fermentation tanks

As we all know, the fermentation tank is the core equipment in a microbrewery, Fermentation tanks are an important part of every brewery, from the smallest home brewery setup to the largest commercial brewery enterprise. Although any receptacle could ostensibly be used as a fermenter, the technology used to manufacture these vessels today is state of the art. You could say that a fermenter is where all the magic happens, where the great craft beer born.

The fermentation tank should be the object of key supervision and management, in order to produce high-quality beer. So the fermentation tank should choose the high-quality, stable work ability. In the begaining of the brewery setup, the investor should buy the reliable cellar tanks, even though you will pay more when you buy the good fermentation tank, but it will produce more great beer and earn more profit for you.

How to plan ahead the brewery fermentation tanks for your brewery?

We have 3 Suggestions for plan ahead the brewery fermentation tanks,our suggestion is that start based on your own room space, the beer output of your sales need, and reserve the location of the fermenter for future expansion.


you need to choose the volume of the fermenter according to the output of the Brewhouse. You can choose single, double, or even multiple times the volume of the Brewhouse output. Of course, this depends on the brewing efficiency of your brewhouse.


you need to arrange each fermentation reasonably according to the output plan. The work schedule of the tank, the cleaning cycle, is their work efficiency at its best, because its operating efficiency is directly related to the speed of your profit return.


As your business continues to expand, you may find that existing fermentation tanks The number is not enough, but the space has been fully utilized, so when building the cellar room in the first time, some fermenters with multiple volumes should be selected, so that ir can reserve space for the subsequent expansion of production capacity. If you want to bigger output, you can choose the unitank act the function of fermenter and BBT, so that you can have more space to arrange the fermenter. Before the fermentation tank enters the site, the drainage ditch should be designed.

For countries with many earthquakes, such as Japan, etc., the fixing bolt holes of the fermentation tank legs should also be designed.

Large fermentation tanks

For large fermentation tank, its production process, transportation, installation, etc. are much more cumbersome than small size fermenters. For the manufacturing process, the large-scale fermentation tank production process requires more lifting tools to participate, the processing process is slower, and the welding requirements for workers are higher. For example, the length of a single weld of a large-scale fermentation tank is longer, which requires welding technicians Stay focused over a longer period of time and ensure continuous consistency in the quality of your welds. In addition, more control measures should be taken to control the roughness and deformation. In the process of assembling the inner and outer cylinders, a vehicle-mounted crane should be used for assembly. This requires the skill of the hoisting workers, the command of the ground cooperating personnel, and only skilled cooperation with each other to ensure the perfect combination of the inner and outer cylinders, instead of friction and scratches.

In addition, during the installation process, large-scale fermentation tanks are more complicated than small-scale fermentation tanks. For example, large-scale fermentation tanks are generally set up outdoors, so the weighing ground should be built in advance, and the ground should be built as horizontal as possible. In fact, in the large fermentation tank in place, its feet are special adjustable feet, which allow it to automatically adapt to minor ground irregularities, keeping the bulky fermenter perpendicular to the ground for stability.

The most common choice-conical fermentation tank

Commercial/Industrial Stainless Steel Conical Beer Fermenter is a Modular cylindrically-conical tank consist of a base tank (BT) and expansion accessories (valves, fittings, armatures, tools …) By choosing and using various types of expansion accessories, it is possible to assemble the tank in several configurations that are optimal for the desired part of the production process. Accessories for expansion of the modular cylindrically-conical tanks: manhole, butterfly valve, Sample valve, Safety valve, Venting valve, Thermometer socket, Manometer, Filling level indicator. Scalable Brewing Solutions for Consistent Taste and Greater Yield.
