Production of beer from the brewery to the bar

First-class quality must be the main ingredient of high-quality beers.

Like all processes, brewing beer goes through a number of stages, each requiring a different set of production tools. Xylem can provide all of this to breweries, from water treatment to filling to waste water disposal.

There’s a lot going on in breweries, but whether it’s providing water for bottling, tank cleaning or waste water disposal, liquid transport is necessary. Reliable and energy efficient pumps are essential in breweries. If any of them need unscheduled service or even replacement, it will cause problems throughout the brewing process.

First-class quality must be the main ingredient of high-quality beers. A lot of water is also needed for heating and cooling as well as for the clean-in-place (CIP) process, although brewers have significantly reduced water consumption for these secondary processes.

No chemicals
Lowara’s borehole pumps raise water from great depths. A standard Lowara e-NSC water pump can transport it to the treatment plant. Efficient hydraulics means the pump exceeds ErP2015 specifications. Gravel filters rid the well water of particles and modern reverse osmosis technology aims to ensure consistent quality brewing water.

Lowara’s multi-stage e-SV centrifugal pump, which can be used as a single pressure pump or as a booster pump, sends water through the pressure pipes. Cleaned and softened without the use of harmful chemicals, the water from the pump enters a UV disinfection system with Wedeco technology, another Xylem brand. Some breweries are already using the latest model, the Spektron UV disinfection system. The flow guidance has been improved by the developers and since the UV output is always adjusted to the water quality and flow rate via a command, the operating costs are particularly low. Water quality is monitored during and at the end of the cleaning process by inline measurement technology from WTW, a company also owned by Xylem.

The retractable connectors for pH probes, which can be used pre-configured, facilitate the work here. And at the end of the fresh water treatment, the Multiline 1000 multi-parameter system offers simultaneous measurement of six parameters, as occurs in drinking water monitoring. WTW technology is also recommended for the brewery laboratory.

Step by step control
In so-called stage control, a sample must be taken and analyzed after each stage of the process, such as pumping from the fermenter to the storage cellar, and of course immediately before bottling. This guarantees the quality of each batch. The samples are then filtered and stripped of carbon dioxide by heating, before the pH, alcohol content, wort and many other values ​​are determined.

The pumping of purified water into the brewhouse in the hot section of the brewhouse is carried out by a Lowara centrifugal pump. Several hygienic beer pumps from Xylem brands, such as centrifugal pumps from Jabsco, are used here. EHEDG-certified units are indispensable in this production process. I

Also, the pumps must not introduce oxygen into the process. Pumps suitable for CIP and SIP cleaning are the first choice in this hygienically demanding process. All components that come into contact with the product are made of 1.4404 stainless steel. Even the high requirements of EC Regulation 1935/2014 can be met by Jabsco.

Boil wort
Various Jabsco stainless steel centrifugal pumps are used during wort boiling, for example to pump the mash into the lauter tun and into the wort kettle. A food grade Hy-Line+ type rotary lobe pump can handle hop dosing as well as wort pitching. The pump series are modular to help find the right connection variant.

The wort reaches the so-called whirlpool, in which hop residues, coagulated proteins and other suspended matter are separated, again via a centrifugal pump. Then it passes through the wort chiller before the yeasts are pitched at relatively low temperatures. Smooth transport is provided by the Hy-line+ rotary lobe pump, whose low shear stress is designed for use with yeast. One of the Jabsco peristaltic pumps would also work.

Breweries use Jabsco food grade rotary lobe pumps for delivery to the main fermentation tank. To pump the new beer, they use Jabsco mobile centrifugal pumps. After several weeks of storage, the beer is now filtered. If the brewer uses diatomaceous earth which is an extremely abrasive medium, Xylem recommends silicon carbide (SiC) slip ring seals in particularly mild centrifugal pumps.

canned beer
Short Time Heat Treatment (STHT) preserves the portion of beer to be canned. Lowara multistage high-pressure pumps generate the necessary pressures in the boiler circuit. Jabso hygienic frequency controlled pumps are used here to extract the beer as well as in the bottling plant. A Xylem rotary piston pump extracts high gas content products when used in conjunction with an upstream screw pre-stage. It can also be used for CIP return, saving a pump at the brewhouse.

The pumps of the Xylem range are used in cleaning systems for bottles and barrels. Jabsco air-operated diaphragm pumps deliver detergents. Standard pumps and high-pressure pumps as well as Lowara multistage centrifugal pumps are also used here. In CIP applications, Lowara’s energy-saving e-series centrifugal pumps with their IE3 motors are particularly practical.

Keg and bottle fillers are also equipped with Xylem technology. The tunnel pasteurizer with heat exchanger connected to the bottle filler is supplied with fresh water and circulating water at different temperatures via Lowara centrifugal pumps.

Sewage pumps
The wastewater treatment plant closes the loop. Flygt pumps are designed to pump sewage and storm water. A ventilation system with Sanitaire aerators ensures sufficient oxygen supply, while continuously variable Flygt submersible agitators support the biological process in the treatment by creating additional horizontal flow in the pond.

The deposit-free and specially shaped propellers offer very high thrust performance with low energy consumption, which means particularly high efficiency. A large number of WTW sensors for all wastewater parameters, as well as the WTW-IQ-Sensor-Net, guarantee a seamless monitoring process.

Please note that not all of these products are available in the UK and Ireland, but alternatives may be available.
