Our microbrewery and pub brewery systems with 2- or 3-vessel brewhouse have 2 principle brewing functions – mashing and wort-boiling, performed by Mash/Kettle combi-vessel.
Our mid-size and bigger microbrewery setups (microbrewery equipment designed with 3-, 4- or 5-vessel brewhouse), have separate Mash Tun and Wort Kettle (sometimes called also Brew -Kettle) to achieve multiple batches/brews daily.

Materials:
stainless steel AISI 304 (SUS 304)
Internal jacket: 3mm thickness
External-Jacket: 2mm thickness
Inner surface treatment: cold-rolled lates 2B finish, grinded to Ra 0,8 µm
External surface treatment: cold-rolled plates 2B finish, grinded to SB
Insulation: Polyurethane 100 mm
As most of brewing equipment Wort Kettle is Insulated jacketed (double-walled) cylindrical vertical stainless-steel vessel (AISI 304) with 4 adjustable legs. Internal vessel surface is polished to Ra 1,6 and its cover is polished as well. External surface is polished to grain 180. Wort-Kettle (brew-kettle) heating is performed by internal welded steam jackets or by internal boiler at maximum 4 bar pressure (0,4 MPa). Steam from the Kettle is vented to steam condenser or to outer space via Ø 250 or 300mm central vent-chimney equipped with wind & rain diffuser
Wort Kettle equipment:
| manway | Ø 450 – 500 mm (glass – 70% of surface) |
| sprayball 2pcs | rotational Alfa Laval sprayballs |
| light | 24 V / 50 W / IP 68 (light lead-in cable piping laid between 2 jackets) |
| socket for thermosensor | G ½“ / Pt 100 |
| steam-venting | Ø 250mm to 300mm |
| wort inlet and outlet | DN40 to DN65 |
| socket for foaming quality sensor | G 1“ |
| wort-pump | 200 to 350 HL/hour with frequency changer |
Wort Kettle heating system:
Internal welded steam jackets or Internal Boiler – max.pressure 4 bars
Vessel heating is provided by two independently controlled steam jackets at 1° C per minute and steam pressure of 4 bar at 150° C temperature. Inlet of steam into steam jackets is controlled from brewhouse control panel by electrically operated solenoid valves, depending on temperature and speed of heating, and also by use of manually operated regulating valves controlled from brewhouse platform.
