4 bbl copper Mash/Lauter tun is a vessel used in the mashing process to convert the starches in crushed grains into sugars for fermentation. TBE mash/lauter tuns are insulated to maintain a constant temperature. The mash/lauter tun 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 are designed to do both decoction mashing and infusion mashing. The mashing tun/kettle is made out of stainless steel or copper.
It 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 sight glasses, CIP jets for simplifying the lautering.

4 bbl copper Boiling Kettle/Whirlpool tun

After lautering, the beer wort is boiled with hops (and other flavourings if used) in a tank known as a kettle/whirlpool tun. 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.
