TRADITIONAL BREWEY SCHLEICHER
Itzgrund, Germany

Retrofit of an existing brewing system and optimisation of process flows at the traditional Schleicher brewery

Schleicher Brewery

The traditional Schleicher Brewery combines the traditional manner of brewing with the latest technology, is now run by the seventh generation of brewers, and features an extensive, diverse and simultaneously unique range. In addition to numerous classic beer varieties, the owner-operated brewery also produces organic Demeter beers in the varieties of shandy, Pilsner and wheat beer.

 

After intensive research, the team also succeeded in developing the first and only gluten-free malt drink and two gluten-free beer varieties (shandy and Pilsener), which are offered together under the brand "Storch im Glück" (engl. stork in luck).

 

Energy optimisation is also a high priority at Schleicher Brewery. Therefore, the evaporation heat generated during wort boiling is recovered and stored in an energy storage unit. The recovered energy is used to preheat the next brew on its way from the pre-run tank to the wort kettle.

Commissioning of minglecontrol at the Schleicher brewery by Christian Roth (seen from behind), an employee of DriveCon GmbH

Project description

The process control failed during the peak season. With minglecontrol, we brought the 4-device brewhouse including malt transport, CIP plants, and fermentation cellar from 2006 up to the latest state of the art in a very short time. Thanks to minglecontrol, production could resume after just two weeks.

 

All necessary brewing, cleaning and fermentation tank recipes were prepared according to customer requirements and pre-tested and verified by us through a simulation at the factory. In addition, the existing hardware components were implemented into the new Siemens S7 1500 control system to ensure long-term spare parts security.

 

The operation of minglecontrol was implemented at Schleicher Brewery in the control room with a stationary PC. Thanks to operation via smartphone and tablet, a touch display on the control cabinet was no longer necessary. The new control system led to process optimisation and allows employees to work in quieter areas.

Special features of the project

Flexibility and customisation

Thanks to its flexibility and very easy adaptability of recipes, minglecontrol is the perfect partner for implementing the very diverse and innovative product portfolio of Schleicher Brewery. The ability to customise minglecontrol to the needs of Schleicher Brewery has also convinced the customers. For example, the software offers the possibility of cleaning the pipelines and vessels according to the strict requirements of the Demeter certification

Fast implementation

Due to its high technical sophistication, minglecontrol is quickly and extensively adaptable. This was also a significant advantage in the implementation into the traditional Schleicher Brewery: production could resume within 14 days after the incident. minglecontrol is thus the optimal solution for the brewery. It serves not only as a replacement for the defective control but also as a simultaneous advancement of the company's technology to the latest standard.

Optimisation of plant use / process optimisation

Schleicher Brewery is a highly automated facility, consisting of a brewhouse, CIP plant, malt storage and fermentation tanks. The high flexibility in managing recipes allows minglecontrol to create an extensive brewing schedule and run it automatically. The brewing process can be monitored and controlled remotely via smartphone and tablet. The brewmaster receives status messages and potential user interactions via push notification on their mobile device.

Optimisation of lautering

In addition to the general plant utilisation, the regulation of lautering was optimised: Depending on the permeability of the spent grain cake (differential pressure), the cutting with the raking machine is only so deep that the wort flow runs as quickly and optimally as possible without stopping the entire lautering and promoting turbidity. To improve the quality of the clear wort, the lautering time was further reduced. Lautering times between 75 and 90 minutes are possible. Additionally, minglecontrol meets another speciality of Schleicher Brewery by allowing a brew to be divided into several fermentation tanks in desired partial quantities.

Use of the "first brew", "last brew" function

On brewing days at Schleicher Brewery, a sequence of 6 to 7 brews runs automatically in parallel and consecutively. To optimise this process, the brewery uses the minglecontrol functions first and last brew. When the "first brew" selection field is activated, the recipe sequence is automatically adjusted so that certain pipelines are flushed and emptied again before contact with a new product. Similarly, the "last brew" function is used for flushing vessels and emptying the spent grain pipelines to the spent grain silo after production ends. New batches are not started at specific times but directly through the states of the preceding brew.

Customised logging of processes

A logging function was also integrated into the new software. The processes, steps and parameters to be recorded were defined by Schleicher Brewery to match the facility. The logs generated are always available as PDFs, significantly improving the traceability of the production processes.
