Brewing machines for the production of hopped wort. The most important technical step lies in the boiling of the beer, when the wort (malt extract mixed with water) is boiled with the hops to produce the final product, namely wort. The hopped wort brewing machine (we call this machine also Brewhouse) is the main part of each brewery. It is a compact system whose primary function is the production of hopped wort, using a boiling process and a wort cooling process. Hopped wort is an intermediate in beer production – it is a sugary fluid from water, malt and hop or from their extracts.
The next phase of the beer production cycle is the fermentation and the maturation of the wort. At the end of the fermentation process we get the resulting product – beer.
The brewing machine usually consists of several parts:
Malt-mashing-boiling-tank – mixing the malt scrap in water, boiling of malt mash
Wort-boiling-tank – boiling of wort with hops
Lauter tun – filtration of malt mash (separation of liquid wort from solid malt rest)
Whirlpool – separation of solid parts from hopped wort (it may be used as external part)
– Basic frame with work platform (excluding the smallest brewing machines)
– Pipe system with pumps
– Engines – motors for mixing and cutting of malt mash by stirrers
– Wort cooler (may be used as external part)
– Wort aeration candle (may be used as external part)
– Electric system for measuring and control of the brewing process
The hot water tank and a tank for cold water are usually an external accessories of the brewing machine.
For some of the simpler types of brewing machines, some containers are omitted or function of some vessel is ensured by another container.
