is a constant number of times, and is,
is a weighted value of the pump speed value coefficient,
is the baseline pump speed value.
The main concept of the above formula is:
coefficient of pump speed

At this time, it is indicated that the precipitation amount of the hot coagulated product and the precipitation amount of the lees such as hop residue in the wort do not reach the preset values, and the wort pump may be operated at the reference pump speed value without adding the pump speed value of the barley pump.
Controlling the wort pump to carry out the whirling process in the whirling precipitation stage on the wort at the pump speed value.
After the pump speed value is calculated, the whirling process of the wort pump in the whirling precipitation stage can be controlled under the pump speed value.
The pump speed value calculated by the formula can be adjusted differently according to actual conditions, so that dregs such as hot coagulates and hop residues in the wort can be better separated, and the phenomenon that the separation effect of dregs such as the hot coagulates and the hop residues is poor due to the unreasonable pump speed value of the wort pump is prevented.
S4, obtaining a first precipitation time of the wort according to the pumping speed value of the wort pump, and controlling the rotary precipitation tank to carry out the precipitation process in the rotary precipitation stage on the wort according to the first precipitation time after the rotary precipitation tank finishes the rotary process.
It is understood that the main function of the rotary sedimentation tank is to separate dregs such as hot coagula and hop residue in the wort to obtain clear wort. Therefore, after the whirling process is completed, the wort is precipitated to separate dregs such as hot coagula and hop residue in the wort, and clear wort can be obtained. Wherein, the first precipitation time refers to the required precipitation time after the wort is subjected to the whirling process.
In some embodiments, the first settling time may be obtained through steps S401 to S403, and is as follows:
s401, generating a pump speed value deviation coefficient according to the pump speed value and the reference pump speed value of the wort pump, and obtaining first settling time of wort according to the pump speed value deviation coefficient and the reference settling time.
The reference settling time corresponds to the reference pump speed value, and is set according to the reference pump speed value.
S402, calculating the first precipitation time of the wort by using the following formula,
wherein the content of the first and second substances,
the first precipitation time of the wort is,
in order to shift the coefficient for the pump speed value,
the precipitation time is taken as a reference for precipitation time,
is the weighted value of the first settling time.
The main concept of the above formula is:
pump speed value offset factor
The larger the size, the more the wort is indicatedThe more the precipitate and the dregs such as hop residue are, the first precipitation time of wort is for better separation of the hot precipitate and the dregs such as hop residue in wort
The larger will be.
And S403, after the whirling process is finished in the whirling precipitation tank, controlling the whirling precipitation tank to carry out the precipitation process in the whirling precipitation stage on the wort according to the first precipitation time.
After the first precipitation time is calculated, the whirling precipitation tank can be controlled to carry out the precipitation process in the whirling precipitation stage on the wort within the first precipitation time after the whirling process is finished.
The first precipitation time obtained through the formula can be used for precipitating and separating dregs such as the precipitation amount of the hot coagulates and the hop residues in the wort according to different actual conditions, so that the problem of taste when subsequent fermentation and yeast recovery are influenced due to the poor separation effect of the dregs such as the precipitation amount of the hot coagulates and the hop residues in the wort caused by overlong or overlong precipitation time is prevented.
And S5, acquiring a second turbidity value of the wort when the precipitation process is finished, and finishing the precipitation process of the wort if the second turbidity value is less than or equal to the preset turbidity value.
Wherein the second turbidity value refers to the turbidity value of the wort after the precipitation process of the wort in the process of brewing the beer by the spartina anglica polysaccharide, and the preset turbidity value refers to the preset turbidity value of the wort after the precipitation process of the wort in the process of brewing the beer by the spartina anglica polysaccharide.
In practical application, if the second turbidity value is less than or equal to the preset turbidity value, the turbidity value of the wort is smaller than the turbidity value of the wort required to be achieved, or equal to the turbidity value of the wort required to be achieved, the precipitation amount of the hot coagula in the wort and dregs such as hop dregs are completely separated, and therefore the precipitation process of the wort can be finished.
S6, if the second turbidity value is larger than the preset turbidity value, continuing the precipitation process of the wort, wherein the total time length of the precipitation process does not exceed the preset maximum precipitation time.
In practical applications, if the second turbidity value is greater than the preset turbidity value, it is indicated that the wort turbidity value is greater than the required wort turbidity value, and the precipitation amount of the hot coagulated product in the wort and the dregs such as hop residue are not completely separated, so that the wort is required to be continuously precipitated.
It should also be noted that the precipitation time is not too long, otherwise off-flavours tend to occur, and therefore the total length of the precipitation process may not exceed the preset maximum precipitation time. Wherein, the preset maximum precipitation time refers to the longest length of the precipitation process which is preset.
In some embodiments, in order to make the calculated first settling time more suitable for the actual application scenario, the present solution further provides steps S601 to S604 to adjust the calculated first settling time.
S601, acquiring a preset weight interval of the sediment corresponding to the first volume value of the wort, and taking the minimum value of the preset weight interval as the first sediment weight of the sediment.
In practical applications, the thermal coagulum is a coagulum that solidifies out at a higher temperature. Above 60 ℃, the thermal concretion can be separated out continuously, and the thermal concretion can not be separated out below 60 ℃. The precipitation amount is about 0.3% to 0.7% of the wort amount.
Therefore, the weight of the dregs (i.e. the precipitate) separated from the wort after the whirling precipitation is in a certain corresponding relationship with the volume of the wort.
Wherein, the preset weight interval refers to the precipitate weight interval corresponding to the first volume value; the first sediment weight refers to the smallest weight value in the sediment weight interval.
S602, obtaining a second precipitation weight of the precipitate in the wort after the whirling precipitation stage, and if the second precipitation weight is less than the first precipitation weight, taking a first volume value of the wort corresponding to the second precipitation weight as a target volume value.
Wherein the second precipitation weight refers to the weight of the precipitate separated from the wort after the rotary precipitation stage; the target volume value refers to the volume value corresponding to the first settling time that needs to be adjusted.
It can be understood that if the second deposition weight is smaller than the first deposition weight, it indicates that the second deposition weight does not reach the deposition weight interval corresponding to the first volume value, and it is likely that the deposition is not completely deposited, so the first deposition time can be adjusted to make the wort deposition more sufficient.
S603, when the next target volume value under the same condition appears, acquiring a weight value of first settling time corresponding to the target volume value, and taking the weight value of the first settling time as a first time weight value.
Specifically, when the next target volume value appears under the same conditions of the manufacturing process, the manufacturing raw materials and the like, the weight value of the first settling time corresponding to the target volume value is used as the first time weight value. Wherein the first time weight value refers to a weight value of the first settling time.
For example, when the target volume value is 20m 2 Under the same conditions, the volume of wort at the next time is 20m 2 Then, the weight value of the first sedimentation time corresponding to the target volume value may be used as the first time weight value.
In addition, since the environmental factors are relatively fixed and the changes are slight, the scheme does not take the environmental factors into consideration.
S604, correcting the first time weight value according to the first deposition weight and the second deposition weight to obtain a second time weight value, and adjusting the first deposition time according to the second time weight value to obtain a second deposition time.
In practical application, in order to make the calculated first settling time more consistent with a practical application scenario, the first settling time may be adjusted by correcting the first time weight value.
Wherein, the second time weighted value refers to the corrected first time weighted value; the second settling time refers to the settling time required by the wort calculated according to the second time weight value.
Calculating the difference between the first sediment weight and the second sediment weight, weighting the difference to obtain a second time weight value, calculating the second time weight value by using the following formula,
wherein the content of the first and second substances,
is the weight value of the second time, and,
is a first time weight value and is,
in order to be the first weight of the precipitate,
in order to obtain the second weight of precipitate,
to increase the correction weight value.
As can be seen from the above formula, when
The larger the weight of the precipitate is, the smaller the weight of the precipitate separated from the wort after the whirling precipitation stage is, and the smaller the separated precipitate is, and the corrected second time weight value can be increased by weighting treatment, so that the precipitation time of the wort is increased to make the precipitation more sufficient,
the larger the value of the second temporal weight value after the weighting process is, the larger the value is.
After the second time weight value is calculated, the first settling time can be adjusted through the second time weight value to obtain a second settling time.
Adjust first settling time through above-mentioned mode, can prevent that the wort from deposiing insufficient problem in first settling time, make the second settling time after the adjustment accord with the applicable scene of this scheme more.
