What Automation Features Can Beer Brewing Equipment Include?

Beer brewing equipment can automate temperature control, recipe steps, pumps, valves, water dosing, lautering, boiling, fermentation cooling, tank pressure, CIP, alarms, data logging, and remote monitoring. A PLC can coordinate sensors, VFDs, pneumatic valves, heating and glycol systems, while an HMI stores recipes and displays live process data. A typical mash program may use 63°C and 72°C rests before 78°C mash-out, while automated CIP can control flow, temperature, chemical dosing, and rinse time.

Automation in a brewhouse usually starts with temperature measurement because mash conversion and wort production depend on controlled thermal steps. RTD sensors can feed readings to a PLC, which adjusts steam valves, electric heaters, or circulation pumps according to programmed setpoints.

A brewing recipe can contain several temperature stages instead of one fixed target. A documented 2026 brewing study used 45°C for 30 minutes, 63°C for 20 minutes, 72°C for 10 minutes, and 78°C for 10 minutes before filtration. A PLC can reproduce this type of sequence without requiring the brewer to change each setting manually.

Once temperature control is automated, pump control can be added to manage how wort and brewing water move between vessels. VFDs allow pump speed to change according to process requirements rather than running one motor speed throughout the batch.

For example, mash recirculation may use a lower flow rate than wort transfer. Flowmeters can provide another control input, allowing the PLC to compare actual flow with a programmed range. A controlled pump speed also gives the brewer a repeatable setting that can be recorded with the batch.

Valve sequencing connects those pumping steps into a complete process. Pneumatic valves or motorized valves can open and close according to recipe logic, establishing the correct route before a pump starts.

A programmed transfer might confirm that the destination tank has available volume, open two or more valves, start the pump, monitor flow, and stop the sequence when the target quantity is reached. Interlocks can also prevent a pump from starting when the required flow path is not available.

Water dosing can use the same approach. A flowmeter measures the volume entering the mash tun or hot liquor tank, while the PLC stops the inlet valve after the programmed quantity is reached.

Commercial systems show how automation scales beyond basic brewing controls. GEA, for example, lists craft brewhouse equipment for 20–40 hL batches and larger systems for 40–115 hL cast-out quantities, illustrating that automation can be specified across different production capacities.

Lautering can combine level sensing, pump-speed control, sparge-water dosing, and rake operation. Maintaining a stable liquid level over the grain bed helps keep the process within the brewer's selected operating range.

Automation can also record runoff volume and timing. A brewery producing 8 batches per day, for example, can accumulate hundreds of individual process records in only a few months. Those records can show differences in flow rate, temperature, batch duration, and vessel performance without relying entirely on handwritten notes.

Boiling and whirlpool operations can follow programmed sequences as well. After the kettle reaches the selected condition, the system can start a timed boil, control steam or electric heating, and then switch the valve path for whirlpool transfer.

A published 2013 pilot brewing study used a 75-minute boil and reported approximately 8% evaporation during wort boiling. Such process parameters can be stored in a recipe and linked to timers, heating output, and transfer sequences rather than being entered manually for every batch.

Fermentation introduces another long-duration control task. A temperature sensor installed in each fermenter can continuously report the beer temperature, while glycol valves regulate cooling when the measured temperature exceeds the programmed setpoint.

Separate tanks can run separate profiles at the same time. One tank may remain at a fermentation temperature while another begins cooling for conditioning. The control system can record the temperature history for both vessels, making it possible to review the full fermentation profile instead of checking a few manual readings.

Pressure monitoring can also be automated on unitanks and bright beer tanks. A pressure transmitter provides a continuous reading, while configured alarms can notify operators when a value moves outside its permitted range.

Pressure control should remain coordinated with mechanical relief devices and the vessel's rated design. Software can monitor and control operating conditions, but it does not replace correctly sized pressure-relief equipment.

Cleaning is another major area for automation because CIP combines multiple repeated steps. An automated CIP system can select the tank, establish the valve route, start the circulation pump, control solution temperature, run each cleaning stage for a programmed period, and complete the rinse sequence.

Commercial CIP systems can contain separate tanks for caustic, acid, and disinfectant solutions, together with pumps, valves, measurement devices, and heating equipment. GEA reports that one of its brewery CIP configurations can reduce cleaning time by at least 3 hours and allow production and CIP processes to run simultaneously under the intended system design.

Conductivity, temperature, flow, and return-line measurements can give the CIP program more information than a simple timer. For small and medium breweries, GEA lists CIP systems with 10 hL or 15 hL buffer tanks, hot CIP flow up to 18 m³/h, and cold CIP flow up to 13 m³/h.

Resource control can also be part of the automation package. GEA reports that its Smart Filtration CIP software can reduce energy consumption by up to 46%, while its Smart Filtration Flush system is reported to reduce flush-water consumption by up to 52% compared with its respective predecessor or conventional reference approach. These figures are supplier-specific and should not be treated as universal brewery results.

For breweries evaluating hgmc craft beer equipment, automation can be specified at different levels instead of treating the brewhouse as one fixed package. Basic systems may automate temperature and pump control; higher-level systems can add valve sequencing, recipe storage, fermentation management, CIP, alarms, and production records.

An HMI gives operators one place to see vessel temperatures, tank levels, pump status, valve positions, recipe stages, timers, and alarms. User permissions can restrict access so routine operators can change approved production settings while engineering users can access deeper configuration.

Data logging adds another layer. A system can store batch numbers, temperatures, pressures, flow quantities, alarm events, recipe parameters, cleaning cycles, and operator changes. For a brewery running 5 batches per day, one year of operation could produce records for more than 1,800 batches, depending on the production schedule.

The automation system can also connect to brewery management software or an MES. Production orders, recipes, batch identifiers, material use, process records, and quality data can then move between production equipment and business systems.

For smaller breweries, automatic temperature control, VFD pumps, fermentation cooling, and basic CIP may be enough. Larger breweries may require automated valve manifolds, recipe-driven brewhouse sequences, tank management, historical data collection, remote alarms, and MES integration. The equipment specification should match the number of batches, vessel count, recipe range, staffing pattern, and required production records rather than simply adding every available function.
