TemperatureAs mentioned, the temperature influences the amount of extract produced (yield) and the fermentability of the wort during mashing. In general, the higher the temperature, the greater the yield but the lower the fermentability of the wort.TimeMash times are another factor influencing yield

Dry MillingIn breweries, dry milling is commonly performed by roller mills or hammer mills. If the wort separation involves using a mash tun or lauter tun, roller mills are employed. Hammer mills are largely used for the later generation of mash filters and continuous brewing systems.

Lauter TunThis is a tank with rake arms that rotate and cutting blades that stir through the grain and push the spent grains out of the tun. This can either be done manually or with an automated system, raising and lowering the rake into the grain depending on how cloudy the runoff is and how tight
