The composition of the mash system

The composition of the mash system

The upper part has two kinds of dish-shaped heads and conical heads, dish-shaped heads for small equipment and conical head for large and medium-sized equipment.
Heating method: electric heating, steam heating, direct fire heating.
Insulation material: rock wool, aluminum silicate board
a. Two mash devices:  mash pot + Lauter tank
b. Three devices for  mash:  mash pot + Lauter tank + boiling and rotary  mash tank/mash boiling pot + Lauter tank + rotary  mash tank
c. Four devices for  mash:  mash pot + Lauter tank + boiling pot + spin sink
d. Five devices for  mash: gelatinization pot+ mash pot+Lauter tank+boiling pot+spinning tank
e. Mash auxiliary equipment (auxiliary equipment): boiler (electric boiler, oil-fired boiler, gas boiler), hop Lauter tank, wort balance tank (control the pumping capacity of the pump, stabilize the filter layer structure, and improve the filtration quality), wort Testing table,  mash operation platform,  mash connecting plate, plate heat exchanger, Venturi cross (oxygenation), wort pump (with frequency conversion), hot water tank + hot water pump

Configuration of brewhouse equipment

Usually, the mash workshop is equipped with: three pots and two tanks: gelatinization pot, mash pot, filter tank, boiling pot, and Whirlpool grains. Of course, according to the different process requirements and production capacity, the configuration is also different. For example, the hotel type is generally equipped with two vessels, the small brewery and the test equipment are also equipped with three-vessel and four vessels.

Rice cooking pot、mash pot

Rice cooking pot: It is used to heat and boil auxiliary materials such as rice and part of the malt mash to gelatinize and liquefy starch
The function of mash pot: It is used for the decomposition of malt starch and protein to saccharify starch.
Structure: Inner tank, outsourcing, heating jacket, stirring system, cleaning device, etc.

Lauter tank

Function: separate wort and spent grains to get clear wort.

Structure: Inner tank, outsourcing, outriggers, sieve plate, tiller system, wort collection, dregs washing system and cleaning system, etc.

Discharge method: Discharge is divided into manual discharge and automatic discharge (dry discharge), manual discharge is used for small equipment, and automatic discharge is used for large and medium-sized equipment;

Sieve plate: The sieve plate is divided into a welded sieve plate and a milled sieve plate; the wedge-shaped gap of the milled sieve plate is 0.7mm, and the international project generally uses the milled sieve plate.

boiling pot

Purpose: Evaporate excess water; destroy enzyme activity, stop biochemical changes, and fix wort composition; wort sterilization; leaching of active ingredients in hops;
Method: jacket heating, internal heating (internal heater), external heating (heat exchanger), pressure boiling.
Structure: composed of inner tank, heater (or jacket), cleaning device, etc.

Whirlpool tank

Function: Separation of thermal coagulation and hop lees.
Structure: composed of the inner tank, outsourcing, cleaning device, etc.
Form: small equipment is cone bottom, large and medium equipment is flat bottom, inclined bottom.

Wort cooling and oxygenation

Cooling is to make the wort temperature meet the requirements of yeast inoculation; oxygenation is for the needs of yeast reproduction.
Cooling equipment: thin plate heat exchanger - the advantages are high heat transfer coefficient, compact structure, and small footprint.
Cooling method: There are single-stage and double-stage points.
Oxygenation equipment: Venturi tube (or cross)
