Can We Overcome Bottlenecks In Our Brewery And Engineer Our Controls For The Future At The Same Time?
What Our Client Said
We’ve reached production capacity with our current fermentation cellar, and we need a plan to expand our operations.
What We Heard
We don’t just want to increase our production capabilities, we need to be ready for future improvements and expansion as well.
What We Did
First, LSI listened carefully to the customer and performed an in-depth analysis of the current production infrastructure and controls. Not only was the existing fermentation cellar control system very rudimentary, a good portion of the control relied upon manual input. In addition, batch reporting and quality control was labor intensive and time consuming. LSI developed a new system to control the tanks, automatically adjust setpoints and record pertinent data so operators spend less time fiddling with controls and more time making beer.
- Project management
- Electrical design
- VBA / SQL programming
- PLC and HMI programming
- Mechanical design
- 3D modeling
- Panel fabrication
The control system consisted of:
- CompactLogix controller
- Hope industrial touch screen
- Intel NUC computer running Factorytalk SE
- Remote I/O consists of WAGO Modular I/O (existing fermentation cellar) and 1794 Flex I/O (new fermentation cellar) communicating via ethernet
The Results Speak For Themselves
- The new control system is easily scalable to include more tanks
- Adding a new tank is as easy as “copy and paste”
- Standardized graphics mean no new screens need to be made for new tanks
- The system allows brewers to input multi-stage fermentation recipes that will hold the temperature of different parts of the tank at their setpoint until the stage timer advances, or until an operator acknowledges that a stage is done
- Each recipe can have up to 10 stages, with top, middle and cone temperature setpoints for each stage
- An array of 100 recipes, with the ability to add additional recipes, allows for many different brew types
- Additional recipes are easy to add
- Tank temperatures, setpoints, glycol jacket solenoid states and other data points are logged in FactoryTalk
- Brewhouse data is logged on each batch of beer (up to six batches can go into a fermentation vessel)
- Reports are automatically generated at the end of each batch
Alarms / Notifications
- Email alerts are sent if high-priority alarms occur along with a timestamp and short description
- Brewers will be able to remotely access the HMI using VNC on their computers, phones and tablets, as well as troubleshoot the HMI or PLC with VPN access
- This free software allows screen sharing and does not log out the physical user when a remote user connects
- This system allows a brewer (or potentially an LSI employee) to directly query the SQL database on the HMI if custom reports or more advanced data analysis are required
LSI listened, then developed a custom solution by utilizing products and knowledge from the global vendors best suited for the project. Because LSI is independent and not owned by a manufacturer, we were able to put the customer’s needs first – selecting the best technology for the job. The scalability and automated reporting provided by these systems has allowed the customer to expand their operation with confidence.
