Mash tun
Mash tun is a vessel used in the mashing process to convert the starches in crushed grains
into sugars for fermentation. TBE mash tuns are insulated to maintain a constant
temperature. The mash tun can be single-functional or can also have a false bottom
and spigot so that the sparging process can be done in the same vessel. Steam jacket design
will allow the TBE systems to do both decoction mashing and infusion mashing.
Lauter tun
The lauter tun is used for filtering and clarifying the sugar liquid (called wort) out of the heated
water-malt mixture (called mash) that comes from the mashing tun.
The lauter tun typically has the same capacity as the cooking tun and can also be made out of
stainless steel or copper cladding. It has a design with a false bottom in stainless steel v-wire
and a raking gear that has the function of an agitator, a rake and a spent gain remover. This is
a very unique and helpful tool because after filtering the spent grains will be removed from the
lauter tun, saving a lot of time and energy of the brewmaster. Furthermore the lauter tun can be
equipped with additional accessories such as collect rings, backwashing rings, sight glasses,
CIP jets for simplifying the lautering.
Boiling Kettle/Whirlpool Tun
After lautering, the beer wort is boiled with hops (and other flavourings if used) in a large tank
known as brew kettle. The boiling process is where chemical and technical reactions take place,
including sterilization of the wort to remove unwanted bacteria, releasing of hop flavours, bitterness
and aroma compounds through isomerization, stopping of enzymatic processes, precipitation of
proteins, and concentration of the wort.
At the end of the boil, the hopped wort settles to clarify in a vessel called a "whirlpool tun" which
has is a tangential inlet of wort. Thus, a vortex is formed when the wort is infused along the arc
inside surface, so that the more solid particles in the wort are separated out. Whirlpool can happen
in the kettle because there is no obstacle inside the kettle.
Hot Water Tank
Hot water tank, called hot liquor tank in a brewery, is the buffer tank that contains hot water that
will be used to sparge the grain bed during lautering to extract a maximum of sugars out of the malt.
This hot water storage tank is almost always insulated and can be heated through steam or an
electric coil.
Brewhouse is various in combination of vessels with four steps mashing,
lautering, boiling, whirlpool as follow:
