Saccharifying and heating device and method for brewing

[0023] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0024] Please refer to figure 1 , the present invention provides a beer brewing saccharification heating device, comprising: a saccharification container 1 for placing malt, a water pump 3 and a heating module 4, the saccharification container 1 is provided with a liquid outlet 101 and a liquid inlet 102; The liquid outlet 101 is sequentially connected to the water pump 3 and the heating module 4 through the pipeline 5 and is connected to the liquid inlet 102. The electric heating element of the heating module 4 is arranged outside the pipe body 5, and the electric heating element generates Heat is exchanged with the liquid flowing through the pipe to achieve the effect of heating the liquid. The liquid outlet 101 is located at the bottom of the malto-mashing container 1 , and the liquid inlet 102 is located at the top of the malto-mashing container 1 . The beer brewing and saccharification heating device further includes a temperature sensor 2 connected in series between the liquid outlet 101 and the water pump 3 .

[0025] Due to the adoption of the above technical solutions, the present invention heats rapidly, and the liquid temperature difference in the entire saccharification container is small, and the present invention is simple to implement, small in space, power saving, accurate in temperature control, and high in maltosaccharification efficiency.

[0026] In the beer brewing process, wort preparation is an essential step. The saccharification process is to decompose the macromolecular storage substances in the malt under the action of hydrolase, water and heat. Fermented wort.

[0027] Saccharification is divided into three stages. First, the liquid is heated from room temperature to the set saccharification temperature. When the water temperature reaches the set temperature, the malt is put into the saccharification container so that the malt is soaked in hot water for a period of time. The saccharification process When finished, remove the spent grains and heat the wort to a boil at 100°C for one hour.

[0028] In the prior art, when boiling water (such as a kettle), heating is performed at the bottom, which is inefficient, resulting in a relatively low malt degree. The technical solution of the present invention makes the water flow during the heating process, so that the water flowing through the heating pipe is heated in the pipeline, thus greatly improving the efficiency, so the biggest effect is that the wort and malt obtained in the same time will be much higher.

[0029] The present invention also provides a beer brewing saccharification heating method, particularly a method for brewing ale beer, which adopts the above-mentioned beer brewing saccharification heating device, comprising the following steps:

[0030] Step 1, pour 6L of room temperature pure water into the saccharification container 1, turn on the water pump 3 to extract the water in the saccharification container 1 from the bottom and send it to the heating module 4;

[0031] Step 2, turn on the power supply of the heating module 4 so that the heating module 4 generates heat, thereby heating the liquid flowing through the heating module 4, and the liquid passing through the heating module 4 flows back to the saccharification container 1;

[0032] Step 3, after the temperature of the liquid in the saccharification vessel 1 reaches 45°C, put 1KG of malt into the saccharification vessel 1;

[0033] Step 4, continue to keep the heating module 4 in a working state, so that the temperature of the liquid reaches 65°C;

[0034] Step 5, when the liquid in the saccharification vessel 1 reaches 65°C, soak the wort in the saccharification vessel 1 for one hour at this temperature for saccharification; The liquid in the saccharification container 1 is in a state of flowing from top to bottom, and at the same time, the liquid in the saccharification container 1 is kept at 65°C by controlling the on and off time of the heating module 4;

[0035] Step 6, after the saccharification process is over, take out the spent grains;

[0036] Step 7, boiling stage: continue to heat the wort in the mashing container 1 until 100 ° C, still adopt the above-mentioned water circulation heating mode and continue for one and a half hours, so that the wort in the entire mashing container 1 is heated evenly;

[0037] Step 8, enter the fermentation stage of beer brewing after the wort is cooled.

[0038] During the whole process, the water pump keeps working, pumping out the liquid at the bottom of the saccharification container and sending it to the heating module. Since the heating module is connected to the 220V power supply, it will generate heat, and the generated heat will be taken away by the liquid flowing through the heating module, thereby Achieving the effect of water temperature heating.
