Information pertaining to the piping layout and the position of the valves
By default, the Braumeister uses 3 feed-through and drain valves on the
bottom as well as one valve on the vessel itself. Valves at the bottom must
be positioned differently depending on the application and the section of
the brewing process. The valve on top of the vessel is used to remove the
wort; at the same time it serves as inlet for the whirlpool application. The
following description of the brewing process describes the relevant valve
positions again and in more detail.
Information about the cooling jacket and water quality
In order to optimise the cooling effect, relatively cold water must be used
as cooling medium. The greater the temperature difference between the
cooling water and the temperature of the wort, the faster the cooling
process is ensured. The so-called “whirlpool effect” causes the wort to flow
in a circular current. This also accelerates the cooling effect (see chapter
“Cooling”). From Braumeister 500 l we recommend the pre cooling from
100°C down to approx. 60°C bei the cooling jacket in the Braumeister and
the cooling down to fermentation temperature by an adequate plate chiller.
In order to prevent corrosive damage, clogging or contamination inside
the double- walled shell, only clean water/cooling medium must be used
that does not contain iron particles. Therefore, do not use pipes/fittings or
similar equipment made of steel as supply lines to the double-walled shell.
Prior to starting the operation, a water analysis may be required. You may
install screens and filters in order to prevent dirt and iron particles to enter
the system.
