[0072] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0073] Refer to Figure 1 As shown, a method for efficient fermentation control of malt beer includes:

[0074] Allocate the fermentation rate according to the urgency of malt beer fermentation. The fermentation rate of malt beer is divided into a standard fermentation rate and an accelerated fermentation rate. The standard fermentation rate and the accelerated fermentation rate are obtained based on historical data, and the standard fermentation rate and the accelerated fermentation rate are the rates that have the least impact on the fermentation parameters of malt beer;

[0075] Monitor the fermentation rate of malt beer, give an early warning for the malt beer with abnormal fermentation rate, and suspend the fermentation of malt beer;

[0076] Establish a fermentation rate control model for malt beer;

[0077] Based on the fermentation rate control model of malt beer, obtain the fermentation rate adjustment plan for malt beer. After adjustment using the fermentation rate adjustment plan for malt beer, restart the fermentation of malt beer;

[0078] Analyze and obtain the drinking preferences of different drinking users, and form a fermentation parameter model of malt beer according to the drinking preferences of different drinking users;

[0079] Generate a recommended parameter package for malt beer according to the actual drinking preferences of drinking users;

[0080] Optimize and set the fermentation parameters of malt beer using the recommended parameter package for malt beer to obtain the adjusted fermentation parameters;

[0081] Ferment the malt beer according to the adjusted fermentation parameters.

[0082] Refer to Figure 2 As shown, monitoring the fermentation rate of malt beer includes the following steps:

[0083] According to the urgency of the malt beer fermentation, divide the fermentation time period of the malt beer into a high fermentation time period and a normal fermentation time period. During the high fermentation time period, ferment at an accelerated fermentation rate, and during the normal fermentation time period, ferment at a standard fermentation rate;

[0084] During the high fermentation time period, obtain the high fermentation time threshold value of the malt beer fermentation;

[0085] During the normal fermentation time period, obtain the normal fermentation time threshold value of the malt beer fermentation;

[0086] Monitor and obtain the fermentation rate of the malt beer in the previous hour, and determine whether the time period of the previous hour is a high fermentation time period or a normal fermentation time period;

[0087] If the time period of the previous hour is a high fermentation time period, compare the accelerated fermentation rate of the previous hour with the high fermentation time threshold value. If the proportion of the high fermentation time threshold value of the previous hour exceeding the accelerated fermentation rate is greater than the first preset value, it is determined that the malt beer fermentation in the previous hour is in an abnormal state, give an alarm, and suspend the malt beer fermentation. Otherwise, it is determined that the fermentation state is normal;

[0088] If the time period of the previous hour is a normal fermentation time period, compare the standard fermentation rate of the previous hour with the normal fermentation time threshold value. If the proportion of the normal fermentation time threshold value of the previous hour exceeding the standard fermentation rate is greater than the first preset value, it is determined that the malt beer fermentation in the previous hour is in an abnormal state, give an alarm, and suspend the malt beer fermentation. Otherwise, it is determined that the fermentation state is normal.

[0089] Since the fermentation rate of malt beer will affect the final product of beer fermentation, therefore, in order to avoid the influence, obtain the standard fermentation rate and the accelerated fermentation rate. The standard fermentation rate and the accelerated fermentation rate are respectively the speeds that have the least impact on the final product of beer fermentation under low-speed fermentation and high-speed fermentation conditions. Thus, the standard fermentation rate and the accelerated fermentation rate can be used in combination to control the overall fermentation time of malt beer, and then meet some urgent situations of malt beer fermentation, such as the situation where the demand suddenly expands, and increase the production volume while ensuring the quality;

[0090] Therefore, it is necessary to control the speed so that the difference between it and the standard fermentation rate and the accelerated fermentation rate is within the allowable range. Otherwise, it may cause a greater impact on the final product of beer fermentation.

[0091] Refer toFigure 3 As shown in Figure 3 , establishing a fermentation rate control model for malt beer includes the following steps:

[0092] Obtain the temperature range and stirring speed range for the fermentation of malt beer;

[0093] Divide the temperature range at equal intervals to obtain at least one temperature identification point;

[0094] Divide the stirring speed range at equal intervals to obtain at least one speed identification point;

[0095] Randomly pair at least one temperature identification point and at least one speed identification point to obtain at least one control group;

[0096] Obtain the fermentation rate of malt beer under the conditions of the control group;

[0097] Fit the control group and the fermentation rate of malt beer to obtain a fermentation rate fitting function, where the control group is the independent variable and the fermentation rate of malt beer is the dependent variable.

[0098] The function of establishing a fermentation rate control model for malt beer is to obtain the corresponding temperature and stirring speed according to the fermentation rate of malt beer, and then make corresponding adjustments according to the obtained results, thereby controlling the fermentation rate.

[0099] Refer to Figure 4 As shown in Figure 4 , based on the fermentation rate control model of malt beer, obtaining a fermentation rate adjustment plan for malt beer includes the following steps:

[0100] Substitute the standard fermentation rate into the fermentation rate fitting function to inversely solve the standard temperature and standard stirring speed for the fermentation of malt beer;

[0101] Substitute the accelerated fermentation rate into the fermentation rate fitting function to inversely solve the accelerated temperature and accelerated stirring speed for the fermentation of malt beer;

[0102] Take the standard temperature and standard stirring speed as the ordinary adjustment plan for the ordinary fermentation period;

[0103] Take the accelerated temperature and accelerated stirring speed as the accelerated adjustment plan for the high fermentation period;

[0104] Summarize the ordinary adjustment plan and the accelerated adjustment plan to obtain a fermentation rate adjustment plan for malt beer.

[0105] Since fermentation involves ordinary fermentation and accelerated fermentation, it is necessary to make separate adjustments during the two fermentation processes. Therefore, the formed fermentation rate adjustment plan includes an ordinary adjustment plan and an accelerated adjustment plan.

[0106] Analyzing and obtaining the drinking preferences of different drinking users includes the following steps:

[0107] Classify the alcohol content of beer for different drinking users, and summarize the alcohol content of beers with a difference less than the second preset value into beer alcohol content categories to obtain at least one beer alcohol content category.

[0108] Different drinking users have different requirements for the alcohol content in beer, and the alcohol content has a great impact on the taste of beer. Therefore, it is necessary to perform differential fermentation according to the requirements of different drinking users for the alcohol content in beer. To reduce the workload, classify the alcohol content of beer for different drinking users, and process the requirements in the beer alcohol content category in the same way, which will not have too much impact on the actual requirements.

[0109] Refer to Figure 5 As shown, according to the drinking preferences of different drinking users, forming a fermentation parameter model for malt beer includes the following steps:

[0110] Obtain the pH value range, dissolved oxygen concentration range, and substrate content range for beer fermentation;

[0111] Equally divide the pH value range at equal intervals to obtain at least one pH identification point;

[0112] Equally divide the dissolved oxygen concentration range at equal intervals to obtain at least one dissolved oxygen identification point;

[0113] Equally divide the substrate content range at equal intervals to obtain at least one substrate identification point;

[0114] Randomly pair at least one pH identification point, at least one dissolved oxygen identification point, and at least one substrate identification point to obtain at least one parameter group;

[0115] Under the conditions of the parameter group, obtain the alcohol content of beer;

[0116] Fit the parameter group and the alcohol content of beer to obtain a fermentation parameter fitting function, where the parameter group is the independent variable and the alcohol content of beer is the dependent variable.

[0117] The fermentation parameter model of malt beer is to reverse solve the pH value, dissolved oxygen concentration, and substrate content that ferment the alcohol content of this beer according to the alcohol content of the beer. Thus, the fermentation parameters can be adjusted accordingly, and then the alcohol content of the finally fermented malt beer can be the required value, thereby meeting the needs of different users.

[0118] Refer to Figure 6 As shown, according to the actual drinking preferences of drinking users, generating a recommended parameter package for malt beer includes the following steps:

[0119] Obtain the requirement for the alcohol content of malt beer in the actual drinking preferences of drinking users to obtain the actual beer alcohol content;

[0120] Substitute the actual beer alcohol content into the fermentation parameter fitting function, and solve for the recommended parameter set by inverse solution. Use the recommended parameter set as the recommended parameter package for malt beer. The recommended parameter set includes the recommended pH value, the recommended dissolved oxygen concentration, and the recommended substrate content.

[0121] Refer to Figure 7 As shown, use the recommended parameter package for malt beer to optimize the fermentation parameters of malt beer. The steps to obtain the adjusted fermentation parameters are as follows:

[0122] Obtain the actual pH value, the actual dissolved oxygen concentration, and the actual substrate content in the fermentation parameters of the current malt beer;

[0123] Subtract the actual pH value from the recommended pH value to obtain the pH adjustment value;

[0124] Subtract the actual dissolved oxygen concentration from the recommended dissolved oxygen concentration to obtain the dissolved oxygen concentration adjustment value;

[0125] Subtract the actual substrate content from the recommended substrate content to obtain the substrate content adjustment value;

[0126] Use the pH adjustment value, the dissolved oxygen concentration adjustment value, and the substrate content adjustment value as the adjusted fermentation parameters.

[0127] The adjustment is carried out on the basis of the existing fermentation parameters. Therefore, it is necessary to calculate the pH adjustment value, the dissolved oxygen concentration adjustment value, and the substrate content adjustment value. When the adjustment amplitudes are the pH adjustment value, the dissolved oxygen concentration adjustment value, and the substrate content adjustment value, the current fermentation parameters can be adjusted to the recommended pH value, the recommended dissolved oxygen concentration, and the recommended substrate content, so that the alcohol content of the fermented beer is the actual beer alcohol content.

[0128] A high-efficiency fermentation control system for malt beer, which is used to implement the above-mentioned high-efficiency fermentation control method for malt beer, includes:

[0129] A speed distribution module, which distributes the fermentation speed according to the urgency of malt beer fermentation. The fermentation speed of malt beer is divided into a standard fermentation speed and an accelerated fermentation speed. The standard fermentation speed and the accelerated fermentation speed are obtained based on historical data, and the standard fermentation speed and the accelerated fermentation speed are the speeds that have the least impact on the fermentation parameters of malt beer;

[0130] A fermentation monitoring module, which monitors the fermentation speed of malt beer, gives an early warning for malt beer with abnormal fermentation speed, and suspends the fermentation of malt beer;

[0131] A model establishment module, which establishes a fermentation speed control model for malt beer;

[0132] A speed adjustment module, which obtains a fermentation speed adjustment plan for malt beer based on a fermentation speed control model of malt beer. After adjustment using the fermentation speed adjustment plan for malt beer, the fermentation of malt beer is restarted;

[0133] A fermentation analysis module, which analyzes and obtains the drinking preferences of different drinking users, and forms a fermentation parameter model for malt beer according to the drinking preferences of different drinking users;

[0134] A parameter recommendation module, which generates a recommended parameter package for malt beer according to the actual drinking preferences of drinking users;

[0135] A parameter optimization module, which uses the recommended parameter package for malt beer to optimize the fermentation parameters of malt beer to obtain adjusted fermentation parameters;

[0136] A fermentation control module, which ferments malt beer according to the adjusted fermentation parameters.

[0137] Furthermore, this solution also proposes a storage medium, on which a computer-readable program is stored. When the computer-readable program is called, it executes the above-mentioned method for efficient fermentation control of malt beer.

[0138] It can be understood that the storage medium can be a magnetic medium, such as a floppy disk, a hard disk, a magnetic tape; an optical medium, such as a DVD; or a semiconductor medium, such as a solid-state drive (SSD).

[0139] In summary, the advantages of the present invention are as follows: By setting up a fermentation monitoring module, a model establishment module, a speed adjustment module, a fermentation analysis module, a parameter recommendation module, and a parameter optimization module, the speed of malt beer fermentation can be controlled, ensuring that the impact of the malt beer fermentation speed on fermentation parameters is as small as possible, thereby ensuring the fermentation accuracy. At the same time, the overall fermentation speed can also be ensured. In addition, according to the alcohol content requirements of different groups of people, the fermentation parameters are adjusted, so as to ensure that the fermented beer can meet the needs of different groups of people specifically, making the fermentation more flexible.
