Fermentation and maturation units are the compact units with cylindroconical tanks and compact cooler for fermentation and maturation of wort that require only very simple installation without piping and electrician work. During the fermentation and maturation of wort made in brewhouse the wort becomes the final drink – beer. Time parameters of the fermentation and maturation process depend on the type of beer, the set pressure in the cylindrical-conical tanks and the requirements of the brewer.
Fermentation and maturation units are independent mobile devices with the cylindrically-conical tanks including everything that is needed for the both primary and secondary fermentation of beer, bottling and dispensing beer. They consist of these components :

Usual main parameters of the fermentation and maturation of beer:
| Parameters of primary beer fermentation | Beer fermented on tank bottom | Beer fermented on wort surface |
|---|---|---|
| Fermentation temperature | From 6°C to 12°C | From 18°C to 24°C |
| Pressure in the tank | From 0.0bar to 0.2bar | From 0.0bar to 0.2bar |
| Time of the beer fermentation | From 6 to 12 days | From 3 to 9 days |
| Fermentor type | CCT, OFV | CCT |
| Parameters of secondary beer fermentation | Beer fermented on tank bottom | Beer fermented on wort surface |
|---|---|---|
| Fermentation temperature | From 1°C to 2°C | From 1°C to 5°C |
| Pressure in the tank | From 0.8bar to 1.5bar | From 0.8bar to 1.5bar |
| Maturation time for the 10° beer | From 14 to 21 days | From 10 to 14 days |
| Maturation time for the 12° beer | From 30 to 60 days | From 21 to 30 days |
| Maturation time for the 14° beer | From 60 to 120 days | From 60 to 90 days |
| Maturation time for the 16° beer | From 120 to 180 days | From 90 to 120 days |
| Fermentor type | CCT, MBTVI, MBTVN, MBTHI, MBTHN | CCT, MBTVI, MBTVN, MBTHI, MBTHN |
The tables above show that for the production of bottom-fermented beers species (eg. Pilsner style), we must consider the time of production of beer by about 50-60% longer than the production of top-fermented beers. As well as the period of production is extending too if we want to produce some stronger beers.
For this reason it is necessary carefully count the number of fermentation and ripening tanks for assess the production capacity of the brewery.
The calculation of the required number of fermentors is quite complex and is always a part of the calculation that we perform for free in the invitation to tender, in consultation business plan of specific customer.
– Each unit contains two cylindrical-conical tanks and an integrated liquid cooler, which ensures cooling of the wort on required temperature. With an integrated cooler it is unnecessary to connect the fermentation units with the external cooling system, but it is necessary to ensure the operating temperature max. 35 ° C in the room (by a ventilation or air conditioning system on hot days).
– Each unit contains 2 CCT and is not equipped with an integrated cooler. One or several FUEC units share a common cooling unit that can be equipped with an integrated condenser (located completely in the interior) or with an external condenser (the condenser of cooler is located in the exterior – requires installation by a qualified refrigeration technician).

– CCTs are produced as non-pressure vessels, designed exclusively for the main fermentation of the wort at pressure 0bar. It is not possible to use these tanks for beer maturation, which must be carried out under mild pressure. In this embodiment, internal welds in CCTs are not grinded as it does not allow the extraction of yeast from the cone without a pumping of beer into another maturation tank. Therefore, the fermentation tanks are dimensioned to sufficient temperature for the main fermentation, but not for the maturation of beer.
– CCTs are produced as pressure vessels designed both for the main fermentation of the wort, and also for the subsequent maturation of beer under pressure up to 1.5bar. In these CCTs it is possible to switch from the primary fermentation to maturation of beer in the same container. But it is always better to pump beer into another clean tank because of better separation of the beer from the settled yeast. In this embodiment, internal welds are grinded to the roughness of Ra 0.8, which significantly improves the slip of settled yeast into a receiving tank cone. This design allows also only hand-filling of beer into kegs and bottles. Overpressure of 1.5bar is not sufficient for quick machinery filling of beer into kegs or bottles.
– CCTs are produced as pressure vessels designed both for the main fermentation of the wort, and also for the subsequent maturation of beer under pressure up to 3.0bar. In these CCTs it is possible to switch from the primary fermentation to maturation of beer in the same container. But it is always better to pump beer into another clean tank because of better separation of the beer from the settled yeast. In this embodiment, internal welds are grinded to the roughness of Ra 0.8, which significantly improves the slip of settled yeast into a receiving tank cone. Overpressure of 3.0bar is sufficient for quick machinery filling of beer into kegs and bottles.
According to requirements and financial possibilities of customers we produce fermentation tanks at two classes of quality:
– High quality workmanship of all parts, welded joints and surfaces. The outer surface is unified. All functional armatures and fittings that have an impact on the reliability and safety of the products are made in Europe or in the USA. 100% inspection of all welds and joints. 100% guaranteed surface roughness on the inside of the containers. Perfectly smooth inner surface is needed for perfect separation of the used yeast from the beer or cider, especially at single-phase fermentation of beer or cider when the both fermentation and maturation process are provided in the same CC tank. 3 years warranty on stainless steel main parts, 2 years on the armatures. Necessary quality class for the most demanding customers.
– Standard quality workmanship of all parts, welded joints and surfaces. All functional armatures and fittings that have an impact on the reliability and safety of the products are purchased from approved suppliers from Europe, USA and Asia. Inspection of all critical welds and joints. 80% guaranteed surface roughness on the inside of the containers. The inner surface allows sufficient separation of used yeast from the beer or cider, especially at single-phase fermentation of beer or cider when the both fermentation and maturation process are provided in the same CC tank. 2 years warranty on stainless steel main parts, 1 year on the armatures. The usual quality class for most customers.
