Maintenance of fermentation tanks

Let us introduce you to the proper care and maintenance required for any fermentation vessel. If you follow our easy to implement instructions, your FV will not only last for a long time but also produce exceptional beer time after time.

(1)What is the best way to hand clean a fermentation vessel?

When cleaning the fermentation tank, use a soft bristle brush to scrub the surfaces. You should never use a hard bristle brush to scrape a fermentation tank’s interior and exterior. It is very important not to damage the parts of the vessel that comes into contact with the wort.

(2)How often should I get my fermentation vessel instruments checked?

All the instrumentation that supports the FV needs to be checked and calibrated at least once every year.

(3)How do I effectively clean the fermenter’s electrical heating elements?

All electric appliances, instruments, and sensors should be cleaned with extra care. If the solids stuck to the electric heating elements aren’t thoroughly cleaned, they can be scorched during the next brewing batch. This can cause unpleasant burnt flavor notes to appear in your beer batch.

An element can be easily removed out of a FV and then it can be cleaned without damaging the rest of the electronics. By using copper scrubbing brushes, the harder stainless steel won’t be damaged.

Never allow water or steam to come into direct contact with electronic instruments and sensors as this can cause condensation to form in the electric housing.

(4)How do I clean a fermentation vessel after using it to make a beer batch?

The most useful feature of a FV is that the boiling temperatures the wort reaches occurs inside the vessel and this assists in the sanitation process. The heat of the boiling wort actually sanitizes the fermenter so there’s no need to clean it with chemicals.

All you need to do after using the FV is clean it out very well with water after the beer is removed, and then use a soft cloth for wiping. The valves need to be disassembled and cleaned out, the elements have to be scrubbed and then your FV is all ready to go for your next beer batch.

(5)Always remember to clean a new fermenter

If you have purchased a new FV, a deep clean is necessary before you can use it. This is because there is sometimes a tiny amount of welding staining or oil on the actual vessel and there could also be microscopic amounts of welding material on the inside jacket. A thorough cleaning of the vessel includes flushing out the jacket. Once the deep clean is complete, you can even use the vessel to provide sparge water during the mashing process.


(6)If you are not going to be using your FV temporarily, it must be emptied and the remaining tank water and connecting pipes should be drained.

(7)The tank pressure should never exceed 0.17mpa during the fermentation process.

(8)During the elimination process, when the jacket passes the preheating steam, the steam inlet pressure must always be controlled within the working pressure range of the equipment (never exceeding 0.2mpa), or it will cause damage to the fermentation tank.

(9)Negative pressure in the fermentation tank is strictly prohibited during the cooling process and after emptying and solids elimination. This is to avoid pollution and possibly damaging the equipment.

(10)The tank pressure should always be maintained between 0.03 and 0.05mpa. This is to avoid contamination during the fermentation process.

(11)During each operation, the pressure in the air duct must be greater than that in the fermentation tank; otherwise, the liquid in the fermentation tank will flow back into the filter, blocking the filter core or invalidating the filter’s effectiveness.
