Beer is among the top ten alcoholic beverages which delights with its distinctive taste. It comes in numerous varieties and flavors – be it Pilsner, Export, Lager, or Helles. One of them is the delicious JUMO anniversary beer, which was created from a recipe by our market segment manager using magnum, ariana, and saphir hops to celebrate the company's 75th anniversary. And that is by no means everything. After all, an in-house brewing plant was designed specifically for the brewing process. This brewing plant ensures high product quality and a true taste experience through the perfect interaction of all components.
In the brewing process, all JUMO solutions that are relevant for the brewing industry were to be combined in a compact plant that could be used for demonstration purposes in addition to the manufacturing of the anniversary beer. Also, all processes were to be automated, monitored, and visualized as well as have a high level of process and food safety. After brewing, the possibility of CIP cleaning was to be available.

Implementation of the brewing plant
In our search for the necessary engineering expertise and a regional brewery that could build such a plant as well as brew the anniversary beer, we quickly came across 2 companies: (1) Burkard und Gärtner (B+G), which is a specialist in system design and plant engineering, and (2) HUNFELT BRAEU, which is a young brewery just outside of Fulda. As many as 13 innovative JUMO components were used in the brewing plant, as a result of which highly efficient processes and a golden yellow Pilsner with a pleasant bitter note were ensured.
In addition to the mash tun, lauter tun, and wort kettle, the plant was also equipped with a hot water tank. Except for the lauter tun, all containers are electrically heated via their inner walls − JUMO TYA 202 power controllers are used to control the heating elements.
The applied sensors were installed in the plant with the process connections G ½ (hygienic), JUMO PEKA (EHEDG certified), and clamp. They were then integrated via Single Pair Ethernet (SPE), IO-Link, or via a 4 to 20 mA signal.
When measuring the level of the hot water tank, mash tun, and wort kettle, the newly developed JUMO DELOS S02 pressure transmitter is used. The differential pressure measurement under the drop bottom of the lauter tun is performed by the JUMO TAROS S46 H differential pressure sensor.
JUMO flowTRANS US W02 is applied for quantity measurement of the main pour and the post pours. At the outlet of the wort cooler, the new JUMO flowTRANS MAG H20 measures both the totalized flow rate and the temperature. Temperature in the respective containers is determined with the JUMO dTRANS T1000.
In pumps for the water/CIP function and for mash/wort the JUMO ZELOS C01 LS level switch is used for dry-run protection.
The plant is controlled via the JUMO variTRON 500 touch (an automation system with touch panel) and the JUMO smartWARE SCADA (a software for process monitoring and control).
Recipes for individual beer types can be configured intuitively without programming skills using the browser-based software solution JUMO smartWARE Program. JUMO smartWARE Evaluation, another software solution, also enables the recording of all process parameters so that the brewing process can be evaluated and verified with an automated batch report.
During CIP cleaning, the JUMO digiLine CI HT10, a head transmitter with an inductive conductivity sensor, determines the concentration of the different cleaning media via the temperature-compensated conductance in the hot water tank. The respective CIP functions can be configured and verified via the above-mentioned JUMO smartWARE Program and JUMO smartWARE Evaluation.
The brewing plant: A cooperation between JUMO and B+G
The planning of the plant on the basis of an intelligent 3D CAD model and manufacturing methods such as orbital welding technology meant that the project − which was mainly handled by trainees from B+G − was completed in just a few months.
This has resulted in a fully automated brewing plant in compact skid design which is completely made of stainless steel, has an output of 100 liters of cold wort, and which features an automated CIP function (Cleaning in Place). The brewing plant is a classic 3-unit brewhouse with lauter tun. Potential brew size is approximately 100 liters. Depending on the type of beer, this corresponds to a malt pour of approximately 20 kg.
