Description

Technical Field

[0001] The invention relates to the technical field of beer brewing, in particular to a boiling pot for beer brewing and a control method thereof. Background Art

[0002] Beer is a kind of beer made from hops and as the main raw materials, after liquid gelatinization and saccharification, and then liquid fermentation. The content of beer is relatively low, containing various types of saccharides, low-molecular sugars, inorganic salts and various enzymes. The beer fermentation process is a normal life activity that uses the fermentable substances in the wort under certain conditions, and its metabolic product is the desired product - beer.

[0003] The boiling pot is mainly used for boiling wort in beer production. Its structure consists of a pot body, an outer coating layer of an insulation layer, an upper head, a liquid inlet, a liquid outlet, etc. The boiling pot is a device used to boil and concentrate wort in beer production to make the wort reach a certain concentration and add hops to give the wort hop aroma. It is one of the main equipment in the saccharification process.

[0004] After massive search, the prior art is found: Publication No. CN113528258A discloses a boiling pot pressure control system, which relates to the technical field of beer production and solves the technical problem of inconvenient pressure control of the boiling pot. The system includes a boiling pot, a controller, and a secondary steam heater. The pressure discharge port of the boiling pot is connected to the input port of the secondary steam heater through a secondary steam pipe. The boiling pot is provided with a first temperature sensor, and the pressure discharge port of the boiling pot is provided with a first pressure transmitter. The output port of the secondary steam heater is provided with a regulating valve and a pressure relief valve connected in parallel. The controller is electrically connected to the first temperature sensor, the first pressure transmitter, the regulating valve, and the pressure relief valve. The present invention adjusts the opening of the regulating valve and the pressure relief valve in real time through the controller, so that the pressure in the boiling pot is stabilized at the first set value, so that the boiling temperature in the boiling pot is always at the optimal boiling temperature, which can not only ensure the quality of beer, but also improve the recovery rate of secondary steam, thereby achieving energy-saving production.

[0005] To sum up, in the existing beer production process, the wort treated by the boiling pot needs to reach a certain temperature before the subsequent process can be carried out, and the traditional boiling pot heating method mostly adopts direct heating, which cannot guarantee the comprehensive contact of the wort in the boiling pot. Although the wort will churn in the boiling pot after reaching a certain temperature, the temperature rise of the wort mostly depends on the mutual heat transfer between the worts, which leads to the heating efficiency of the wort being limited. After the heating reaches the critical temperature, stopping the heating will still make the temperature in the boiling pot continue to rise, which is easy to cause the boiling temperature of the wort to be too high and cause the wort to deteriorate, and lose the original flavor characteristics of the wort, thereby affecting the subsequent beer production quality. Summary of the invention

[0006] The object of the present invention is to provide a boiling pot for beer brewing and a control method thereof to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a boiling pot for beer brewing and a control method thereof, comprising a boiling pot body, a flow guide pipe, a positioning rod, a liquid inlet pipe, an electromagnetic three-way valve, a heating unit, a control terminal, an exhaust pipe and a circulation pipe, wherein a control terminal is arranged on one side of the boiling pot body, an electromagnetic three-way valve is arranged at the bottom end of the boiling pot body, a connecting pipe penetrating the inner wall of the bottom end of the boiling pot body is connected to the upper end of the electromagnetic three-way valve, a flow guide pipe is connected to the upper end of the connecting pipe, a positioning rod is inserted into the inside of the flow guide pipe, and heating units distributed equidistantly are arranged on the surface of the positioning rod;

[0016] Preferably, an electromagnetic exhaust window is installed inside the exhaust pipe, and the control terminal is connected to the electromagnetic exhaust window.

[0017] Preferably, the upper end of the circulation pipe is connected to the inner wall of the bottom end of the boiling pot body, and the circulation pump and the electromagnetic three-way valve are both connected to the control terminal.

[0018] Preferably, the control method is as follows:

[0019] S1: The liquid inlet pipe injects the wort into the guide pipe, and the control terminal sets the heating temperature of the heating unit in sequence, and the wort is heated step by step as the wort passes through the heating unit from bottom to top;

[0020] S2: The temperature detection module detects the heating temperature of the wort at each stage. When the wort overflowing the diversion pipe does not reach the boiling temperature, the wort is injected into the electromagnetic three-way valve again through the circulation pump, mixed with the unheated wort, and enters the diversion pipe again for stage-by-stage heating again;

[0021] S3: The first temperature sensor measures the internal temperature of the boiling pot body in real time.

After the temperature is measured by the first temperature sensor, when it is close to the set temperature, the set temperature of the heating unit can be adjusted to stably maintain the temperature of the wort, avoiding the deterioration of the wort caused by the temperature inside the boiling pot body exceeding the set temperature of the wort heating after the heating is stopped, thereby ensuring the boiling effect of the wort;

[0025] When the temperature inside the boiling pot exceeds the set temperature, the control terminal can open the electromagnetic exhaust window to dissipate heat inside the boiling pot to prevent the wort from overheating and deteriorating due to the high temperature inside the boiling pot, thereby ensuring the quality of the wort boiling and the quality of subsequent beer brewing.
