Universal mini brewing system

The invention belongs to the brewing technology systems for beer production.

In recent years, more and more new small brewing systems have come onto the market. Most of them are professional systems with capacities of 20, 50, 100 and more liters. These are oversized, over-secured, computer-controlled and therefore too expensive; unaffordable for mass sales. There are currently no solutions in the group of home hobby brewing systems.

This invention solves the following problems:

- professional plant minimization (several liters capacity);

- all processes and phases must exist as in professional brewing plants;

- the plant must have all units (production, fermentation, storage);

- standard elements should be used;

- Simplification for use as a home or hobby appliance.

The plant (see drawing) is constructed like a large industrial two-device brewery. The mash and wort pans are constructed like one pan, the lauter tun has an integrated whirlpool, the fermentation and storage units are integrated and all elements for cooling, water management, pumps, valves, etc. are located in one housing. The production process takes place in the following phases:

- The water in the container (16) is heated by heater (17) and thermostat (18);

- The water is pumped into the mash tun (1) through the suction pipe (15), pump P2 (14), valve (V7) and water pipe (48);

- Lid (4) is opened and malt is added (1 kg);

- The agitator (7) is driven by the electric motor (9);

- The mash is heated in the mash pan (1), from below, gradually (heater (8) and thermostat (12)) infusion process;

- During mashing, water is heated in the container (16);

The water is pumped in through the valve (V8) and pipe (22) so that the bottom (6) is covered;

- After mashing, the mash is pumped through the valve (Vl), pump (Pl), valve (V5) into the spent grain container (5);

- A few minutes of rest (clarification rest);

- Through the pipe (23), valve (V2), pump (Pl), valve (V5), and the pipe (20) the trub wort is briefly pumped back;

- The knives (24) with wings (27) are driven by an electric motor (10) and an axle (25) - clarification;

- During the lautering process, the mash tun can be washed through the pipe (48) and "waste water" can be pumped into the lauter tun through the pipe (20) (as a first step);

- During lautering, the first wort is pumped through the pipe (23), valve (V2), pump (Pl), valve (V4) and the pipe (19) into the wort kettle (the distance between the lauter tun (2) and the spent grain container (5) prevents negative pressure);

The water is pumped several times through the pipe (22) into the lauter tun (tailing);

- Hops are added to the wort kettle from above (lid (4)) and the wort is boiled with stirring (7);

- During wort boiling, the lid (3) of the lauter tun is opened and the spent grain container (5) is removed together with the spent grain (waste);

- The lauter tun is washed and a whirlpool base (47) is inserted in place of the spent grain container;

After wort boiling, the cast wort is pumped tangentially into the whirlpool through pipe (21) and, after a rest period, is let into the lauter tun (2);

- Rash wort particles settle on the whirlpool floor (waste);

- Wort is pumped into the fermentation pot through the pipe (28), the lid (45) is hermetically closed;

- The wort is cooled by the cooling system [compressor (46), condenser (29), valve (V9), pipe (30), evaporator (36), pipe (33)] (thermostat (39));

- Yeast is added, two days of fermentation;

- After fermentation, the young beer without yeast particles is poured into a storage vessel (43) and stored for 14 days (storage room (35)). The resulting CO2 saturates the beer and is released through the reducing valve (41) at a certain pressure;

- After storage, the beer can be enjoyed with or without filtration.

The invention is explained with the help of the drawings:
