BREWORX CLASSIC | Technical specification of the wort brew machine

A typical feature of luxury interior restaurant microbrewery BREWORX Classic is an interior two-vessel or three-vessel brewhouse which includes mash tun, lauter tun and whirlpool integrated into frame with wort cooler, steps, laboratory sink and Control Panel. The brewhouse is available in several design variants.

Brewhouse BREWORX CLASSIC – the beer production from traditional ingredients

Construction of the brewhouse BREWORX Classic allows production of all known types of beers by Czech and foreign recipes, from traditional ingredients (malt, hops, water and yeast), by an infusion and decoction method. If necessary, it is possible to prepare the wort in the brewhouse from concentrate (like in Brewhouses LiteME and LiteWC). Unlike most foreign products our brewhouse is optimized for the production of high-quality bottom-fermented lager beer (pilsner type), or it can be used for brewing any other top-fermented beers.

The volume of the daily brewhouse production is two wort batches in 24 hours.

Available models of the BREWORX CLASSIC brewhouses

Microbreweries BREWORX CLASSIC are delivered with a volume of brewhouse capacity 1.5 HL – 20 HL. Total annual production of the microbrewery is then given by the brewing schedule, number and type of fermentation and maturation vessels, number and type of serving tanks, selected range of beer types and other parameters.

Brewhouse description :

The brewhouse is the main part of each brewery. It is a food machine whose primary function is the production of beer wort. The wort is an intermediate product. The next phase of the production cycle is fermentation and maturation of wort. This raises the final product – beer.

Design of the BREWORX CLASSIC brewhouse

Two design variations : with copper hats and coat, with a polished stainless steel finish

The singleblock BREWORX CLASSIC brewhouse is a compact food machine which includes all necessary equipment to produce 150-2000 liters (it depends on brewhouse type) of beer wort in one batch. It is three-vessels brewhouse wherein two containers are integrated into one cylinder (three separated tanks are available for the brewhouse Breworx Classic 1000-2000). This we have achieved full functionality brewing while we retained the traditional design of the Czech type brewhouse which is ideal for producing of world-famous Czech type beer. However, this brewhouse is fully capable for manufacturing all types of beer, which is produced anywhere in the world.

The brewhouse includes three vessels : mashing-wort boiling kettle, lautering tun, whirlpool (is usable also for collection lautered wort before wort boiling). The lautering tun and whirlpool tank are superposed, so the brewhouse looks like two-vessel machine. It is better because this design saves space in an interior. All three vessels are fixed on common frame and they are easy accessable from an central platform or from rear side of the brewhouse.

The patented design of the brewhouse allows partially to manufacture of two batches of wort simultaneously – a new batch can be mashed immediately after wort boiling while performing whirling of the wort and unloading of a previous batch (it is valid only for version brewhouse with two pumps). This makes it possible to produce two to four doses wort during one day (24 hours) – depending on the type brewhouse and brewing method from 150 to 8000 liters of wort per day.

It is possible to produce wort either infusion or decoction way. Control system of the brewhouse is either semi-automatic or fully automatic – two available versions.

The brewhouse BREWORX CLASSIC includes in standard :

• mash tun – kettel for boiling
• lauter tun – for filtering
• whirlpool – for separation of hop dregs from wort
• laboratory sink
• control panel
• platform with steps
• all pipes and wires connections
• all mechanically or automatically controlled valves and armatures
• electric switchboard cabinet
• control computer

Why to choose the BREWORX CLASSIC ?

Main advantages of the BREWORX CLASSIC compared with brewhouses of other manufacturers:

1. The BREWORX CLASSSIC is a compact standardized wort machine, which is based on a common frame. The brewhouse is easily transportable in one unit, or it can be broken down into 3 smaller parts.
2. Our brewhouse allows the production of almost all types of beers, which are known in Europe and the USA. The BREWORX CLASSIC brewhouse allows the production of beer using both infusion or decoction method.
3. The whirlpool is integrated under the lauter tun. This solution saves space in the brewery (only for brewhouse volumes lower than 1000 liters)
4. The dosage of the raw materials is carried out at the beginning of the brewing process. Brewer does not need to intervene in the brewing process (only automatic version).
5. Two options of wort lautering – gravitational (first phase) and by pump (second phase).
6. The electrical switchgear and the control computer are integrated in the body of the brew house. This solution greatly eliminates the required amount of electrical wiring and electrical work on site.
7. An elimination of the negative influence of water conductivity on beer quality using the deionization belt.
8. The brewhouse construction allows you to start mashing of the second batch during a last phase of the first batch – it speeds up the double brewing process. (It is valid only for version brewhouse with two pumps)
9. The highly efficient heating system of the brewhouse depends on the choosed variation :
   1. Indirect steam heating of the brewhouse dramatically accelerates the wort production process. A hot steam is supplied in the brewhouse from an external electric, gas or pellet steam generator. Due to heat transfer from the steam to the heated product using a big heat transfer area the beer is not locally overheated. This is prevention particularly in beer production completely prevented so. Caramelisation malt, which is undesirable localized heat malt mash (ie. The work), in which the malt mash mashing chars on the walls of the boiler and hence to the formation of carcinogenic substances and spáleninových flavored beer.
10. The placement of the lower engine agitator under the bottom of the brewhouse prevents dripping of grease into the brewhouse.
11. Easy access to all controls and flaps.
12. The unique glass single-hand doors on both tanks. Overpressure manholes may not be opened during wort production, while a slight overpressure in the brewhouse accelerates the brewing process.
13. Exactly calculated sizes of containers to minimize oxidation of wort.
14. An automatic ejection of waste grains.
15. Removable segment sieve with trapezoidal holes allows the perfect lautering of wort. High load capacity of the sieve
16. The possibility of producing beer from barley malt and wheat malt. The brewhouse allows also production beer from malt extract or wort concentrate.

Options and properties

Two raw materials for production of beer wort :

• Classical raw materials : Malt + hops + drinking water + brewer’s yeast + (optionally other ingrediences)
• Beer concentrates : Malt extract + hops + drinking water + brewer’s yeast + (optionally other ingrediences)

Four production capacities of the brewhouse :

• 150-2000 liters of beer wort per day – one batch for 12 hour – source raw materials are malt or malt extract, hops, drinking water and brewer’s yeast
• 300-4000 liters of beer wort per day – two batches for 24 hour – source raw materials are malt or malt extract, hops, drinking water and brewer’s yeast
• 450-6000 liters of beer wort per day – three batches for 12 hour – source raw materials are malt extract, hops, drinking water and brewer’s yeast
• 600-8000 liters of beer wort per day – four batches for 24 hour – source raw materials are malt extract, hops, drinking water and brewer’s yeast

Two available designs :

• SD – Stainless steel design – all vessels are fully made of stainless steel AISI 304
• CD – Copper design – all main parts are made of stainless steel AISI 304, only outer sheath and hats of containers are made of copper.

Two available heating systems :

• EH – Electric heating – the heating of kettel is performed by electric heating elements without the use of heat transfer fluid
• SH – Steam heating – the heating of kettel is performed by hot steam produced by steam generator. Heating by hot steam significantly speeds up the boiling process and it is better for the heated wort (no caramelization of malt). This system requires a connection of the brewhouse to electric, gas or pellet steam generator that is not included in the brewhouse (see an optional accessories).

Two available control systems :

• MC – Manual control – – the brewhouse is manually operated with the support of computer application that guides the user step by step through the production process. Heating of the brewhouse, stirrer speed, the pump running are controlled from a central control panel.
• AC – Automatic control – automatically controlled brewhouse supported by industrial computer which automatically controls the production of wort and requires little user´s interaction. Features such as heating of the brewhouse, stirrer speed, pumps running, valves and control valves are computer controlled and adjusted to a central control panel with touchscreen.

Why choose AC system for brewing control ? Main reasons are :

• Elimination of human errors – machine accurately and timely perform necessary tasks
• Costs saving for owner – only one worker is necessary for manipulating in the brewery
• Minimize the number of error conditions in the brewery – everything is still under control
• Monitoring and registration of the production process into the computer memory
• Minimization of requirements for constant operator attention – early reaction of machine
• Stable quality of beer – standard manufacturing procedures are always observed
• Six pre-programmed recipes – for production of the most known types of beer : Pils, Lager, Black, Weissenbeer, Ale, Special
• Manual brewing mode – for production of all other types of beer
• Special sanitation mode – for automatic cleaning,sanitizing and sterilization of the brewhouse, wort pipes, armatures and other brewery equipment

Recommendation :

We emphatically recommend choose the automatic brewhouse control system for this type of brewhouse and also the automatic control system for media and fermentation & maturation process !

The computer brewhouse automatic control system always ensures the right brewing operations timing without damaged wort batches.

The automatic control system for media and fermentation & maturation process allows automatic monitoring and controlling of the most important parts of beer fermentation and maturation process (from 1 to 30 tanks max) and operations with media.

How looks the automatic control panel ? This is a main menu. Choose one from several beer types or functions then click and go.

Special functions :

• CIP function – the special mode ensures cleaning, sanitization and sterilization of the brewhouse, wort pipes and optionally also other devices in the brewery
