300 L Electric Beer Brewing System

The 300 L electric beer brewing system is designed for craft beer production and is suitable for anyone looking to open a microbrewery or upgrade an existing one. The system features a 2-vessel brewhouse plus a hot water buffer tank and is designed primarily for single-batch operation, with semi-automatic control of mash steps via a touchscreen control panel with Siemens components.

The system can also be used for double-batch operation, with slightly longer production times than systems specifically designed for that workflow. The electric brewhouse is supplied as a pre-assembled monobloc and only requires connection to the electrical and water supply lines. This configuration is also suitable for entrepreneurs who want to power their microbrewery using photovoltaic systems.

The brewhouse includes a touchscreen command panel installed on a stainless-steel platform. From the panel, you can manage the pumps, including speed adjustment via inverter, control the geared motor for the mash tun, view mash and boil temperatures, monitor safety and emergency statuses and check the safety devices installed on the mash tun lid.

Wort/boil & whirlpool pump

The system includes a CSF 1.5 kW pump for hot and cold wort, built in polished AISI 316 stainless steel. It features internal mechanical seals with circulation and is suitable for liquids and solids at temperatures close to boiling.

Fittings and pipework

All connections in the 300 L electric brewhouse use sanitary mandrel fittings. The single supply manifold is connected to the boiler line to speed up pipe cleaning and includes a drain.

• Sanitary tubing, polished inside and out;
• DIN 11851 mandrel fittings;
• Suction DIN 40;
• Delivery DIN 32;
• Butterfly valves with high-temperature gaskets;
• AISI 304 stainless steel;
• TIG welds with internal inert gas (argon) shielding.

Heat exchanger

The system is equipped with an inspectable plate heat exchanger. The plate configuration creates separate channels for the hot and cold fluids, while the corrugated surface generates turbulence to improve heat transfer. Rubber gaskets provide hydraulic sealing, and the plate pack can be adapted or serviced by adding or replacing components.

Control panel

The main electrical panel is built in AISI 304 stainless steel with Siemens components and a touchscreen monitor. The touchscreen provides access to the system controls and semi-automatic functions.

The integrated PLC manages the mash and boil cycle according to time and temperature parameters.
