Description

Technical Field

[0001] The invention relates to the technical field of beer brewing, and in particular to an intelligent control method for controlling the sugar content consistency of three rings of a filter tank. Background Art

[0002] During the operation of the saccharification and filtration tank, the second wort filtration is the key stage for controlling the yield, residual sugar and filtration efficiency. Compared with the first wort filtration, there will be inconsistent sugar content in the three rings during the lees washing process. When the second filtration starts, the sugar content of the three rings is basically the same, but as the filtration process proceeds, differences appear in the sugar content of the three rings, among which the sugar content of the inner ring is significantly higher than that of the other two rings. The high sugar content of the inner ring is mainly due to the problem that the lees cannot be washed easily in the inner ring, resulting in higher residual sugar. High sugar content requires high flow rate for lees washing.

[0003] The existing technology has the following problems:

[0004] In the traditional process, the flow rate, cumulative volume and time point process parameters when filtering the slop water are all formulated by process engineers according to standard formulas and empirical values, and manually input into the Braumat production formula. The Braumat system executes the corresponding procedures and continues to track and adjust during the production process to achieve the process goals. The three-loop process control mainly relies on the Braumat formula to set fixed values, which cannot be adjusted according to the real-time working conditions of the production process. Summary of the invention

[0005] The present invention provides an intelligent control method for three-ring sugar content consistency control of a filter tank, so as to solve the problem that the traditional three-ring process control mainly relies on set fixed values ​​and cannot be adjusted according to the real-time working conditions of the production process.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A method for controlling the sugar content consistency of a three-ring filter tank is provided. The method comprises the following steps:

[0008] Step 1: First, during the filtration process, the total filtration flow rate is controlled to remain unchanged, and the total filtration flow rate is set to L 总 ;

[0009] Step 2: Real-time calculation of the sugar content ratio of the inner ring, middle ring and outer ring flow. The sugar content of the inner ring, middle ring and outer ring are T 内 , T 中 , T 外 , calculate the sugar content ratio a, b, c of the inner ring, middle ring and outer ring:

[0010] a=T 内 / (T 内 +T 中+T 外 );

[0011] b=T 中 / (T 内 +T 中 +T 外 );

[0012] c=T 外 / (T 内 +T 中 +T 外 );

[0013] Step 3: Dynamically allocate the inner ring, middle ring and outer ring traffic according to the real-time proportional relationship. The inner ring, middle ring and outer ring traffic are L 内 , L 中 , L 外 , then the three-ring flow distribution is:

[0014] L 内 =a*L 总 ;

[0015] L 中 =b*L 总 ;

[0016] L 外 =c*L 总 .

[0017] A further improvement of the technical solution of the present invention is that the step 1 further includes the following steps:

[0018] A1: Reasonable planning of pipe network structure;

[0019] A2: Flow control and regulation;

[0020] A3: Control and regulation of water pressure.

[0021] The further improvement of the technical solution of the present invention is that: for the reasonable planning of the pipe network structure, the main filtered water pipeline and the three branch filtered water pipelines are all copper pipes, and the main filtered water pipeline and the three branch filtered water pipelines are connected at a 45-degree angle to ensure that the branch filtered water pipelines should be coordinated with the main filtered water pipeline, and ensure that the design of the diversion pipeline can effectively distribute the water flow and avoid bagging and backflow. The cross-sectional area of ​​the total filtered water pipeline is D 总 , the cross-sectional area of ​​the filtered water pipeline is D 分 , that is, D 总 >D 分 *3.

[0022] A further improvement of the technical solution of the present invention is that for the control and regulation of flow, a total flow control valve will be installed at the inlet of the total filtered water pipeline, and a total flow sensor will be installed at the outlet of the inlet of the total filtered water pipeline. The total flow sensor can monitor the flow in the total filtered water pipeline in real time, thereby controlling the total flow control valve to regulate the flow in the total filtered water pipeline, thereby ensuring the stability of the total filtered flow delivery.

[0023] A further improvement of the technical solution of the present invention is that for the control and regulation of water pressure, a pressure transmitter is installed inside the total filtered water pipeline to adjust the pressure inside the total filtered water pipeline in real time. At the same time, a pressure relief valve is installed in the total filtered water pipeline. Under the joint control of the pressure relief valve and the total flow control valve, the stability of the water pressure inside the total filtered water pipeline can be guaranteed.

[0024] A further improvement of the technical solution of the present invention is that in step 2, corresponding infrared spectrometers are installed in the inner ring, the middle ring and the outer ring, and the sugar content in the inner ring, the middle ring and the outer ring can be monitored in real time by the infrared spectrometer to accurately obtain T 内 , T 中 , T 外 in order to reasonably distribute the filtration flow in the inner ring, middle ring and outer ring.

[0025] A further improvement of the technical solution of the present invention is that: in the step 3, a flow control valve is installed at the inlet of the water separation pipeline, and a flow sensor is installed at the outlet of the water separation pipeline. The flow control valve can be set according to the calculated L 内 , L 中 , L 外 The flow of the three branch filtered water pipes connected to the three rings can be reasonably adjusted according to the value. At the same time, the flow of the three branch filtered water pipes can be monitored in real time through the branch flow sensors.

[0026] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0027] 1. The present invention provides an intelligent control method for the consistency control of the sugar content of the three rings of the filter tank, which monitors the sugar content and flow of the three rings of the filter tank in real time, dynamically adjusts the three ring process based on the sugar content distribution, dynamically ensures the sugar content consistency, and improves the efficiency of washing the slag. Through the intelligent control model, the problem of high residual sugar in the inner ring is solved, and the quality of washing the slag is improved.

[0028] 2. The present invention provides an intelligent control method for controlling the sugar content consistency of the three-ring filter tank. Through reasonable planning of the pipe network structure, control and regulation of the flow rate, and control and regulation of the water pressure, by using copper pipes and small-angle connections, it is possible to ensure smooth pipeline circulation, and through the total flow sensor and the pressure transmitter, it is possible to monitor the flow rate and water pressure in the total filtered water pipeline in real time. Under the joint control of the pressure relief valve and the total flow control valve, it is possible to ensure the stability of the water pressure and flow rate inside the total filtered water pipeline, making the distribution of the three-ring flow of the filter tank more convenient.

[0031] The present invention is further described in detail below in conjunction with embodiments:

[0032] like Figure 1-2 As shown, the present invention provides an intelligent control method for controlling the sugar content consistency of a three-ring filter tank, and the intelligent control method for controlling the sugar content consistency of a three-ring filter tank comprises the following steps:

[0033] Step 1: First, during the filtration process, the total filtration flow rate is controlled to remain unchanged, and the total filtration flow rate is set to L 总 ;

[0034] Step 2: Real-time calculation of the sugar content ratio of the inner ring, middle ring and outer ring flow. The sugar content of the inner ring, middle ring and outer ring are T 内 , T 中 , T 外 , calculate the sugar content ratio a, b, c of the inner ring, middle ring and outer ring:

[0035] a=T 内 / (T 内 +T 中 +T 外 );

[0036] b=T 中 / (T 内 +T 中 +T 外 );

[0037] c=T 外 / (T 内 +T 中 +T 外 );

[0038] Step 3: Dynamically allocate the inner ring, middle ring and outer ring traffic according to the real-time proportional relationship. The inner ring, middle ring and outer ring traffic are L 内 , L 中 , L 外 , then the three-ring flow distribution is:

[0039] L 内 =a*L 总 ;

[0040] L 中 =b*L 总 ;

[0041] L 外 =c*L 总 .

[0042] In this embodiment, the flow is distributed in real time according to the sugar content of the three rings, the proportion of sugar content, and the total flow, while ensuring that the total flow does not change. According to the sugar content proportion, the ring with low sugar content occupies the proportion of faster flow rate, and the ring with high sugar content occupies the proportion of lower flow rate. Dynamic settings are made according to the flow rate and sugar content on site to ensure the consistency of sugar content of the three rings, and an intelligent control model is used to solve the problem of high residual sugar in the inner ring and improve the quality of lees washing.

[0043] like Figure 1-2 As shown, the present invention provides an intelligent control method for controlling the sugar content consistency of a three-ring filter tank, wherein the step one also includes the following steps:

[0044] A1: Reasonable planning of pipe network structure;

[0045] A2: Flow control and regulation;

[0046] A3: Control and regulation of water pressure.

[0047] For the reasonable planning of the pipe network structure, the main filtered water pipeline and the three branch filtered water pipelines are all made of copper pipes. The main filtered water pipeline and the three branch filtered water pipelines are connected at a 45-degree angle to ensure that the branch filtered water pipelines should be coordinated with the main filtered water pipeline and ensure that the design of the diversion pipeline can effectively distribute the water flow and avoid bagging and backflow. The cross-sectional area of ​​the total filtered water pipeline is D 总 , the cross-sectional area of ​​the filtered water pipeline is D 分 , that is, D 总 >D 分 *3.

[0048] For flow control and regulation, a total flow control valve will be installed at the inlet of the total filtered water pipeline, and a total flow sensor will be installed at the inlet and outlet of the total filtered water pipeline. The total flow sensor can monitor the flow in the total filtered water pipeline in real time, thereby controlling the total flow control valve to adjust the flow in the total filtered water pipeline and ensure the stability of the total filtered flow delivery.

[0049] For the control and regulation of water pressure, a pressure transmitter is installed inside the total filtered water pipeline to adjust the pressure inside the total filtered water pipeline in real time. At the same time, a pressure relief valve is installed in the total filtered water pipeline. Under the joint control of the pressure relief valve and the total flow control valve, the stability of the water pressure inside the total filtered water pipeline can be guaranteed.

[0050] In step 2, corresponding infrared spectrometers are installed in the inner ring, the middle ring and the outer ring. The infrared spectrometers can monitor the sugar content in the inner ring, the middle ring and the outer ring in real time to accurately obtain T 内 , T 中 , T 外 in order to reasonably distribute the filtration flow in the inner ring, middle ring and outer ring.

[0051] In step 3, a flow control valve is installed at the inlet of the water separation pipeline, and a flow sensor is installed at the outlet of the water separation pipeline. The flow control valve can be set according to the calculated L 内 , L 中 , L 外 The flow of the three branch filtered water pipes connected to the three rings can be reasonably adjusted according to the value. At the same time, the flow of the three branch filtered water pipes can be monitored in real time through the branch flow sensors.

[0052] In this embodiment, by using copper pipes and small-angle connections, smooth pipeline circulation can be ensured, and the flow and water pressure in the total filtered water pipeline can be monitored in real time through the total flow sensor and pressure transmitter. Under the joint control of the pressure relief valve and the total flow control valve, the stability of the water pressure and flow rate inside the total filtered water pipeline can be guaranteed, making the distribution of the three-ring flow of the filter tank more convenient.

[0053] It is understandable that the present invention provides an intelligent control method for the consistency control of the sugar content of the three rings of the filter tank. On the one hand, by real-time monitoring of the sugar content and flow of the three rings of the filter tank, combined with the sugar content distribution, the three-ring process is dynamically adjusted to dynamically ensure the sugar content consistency and improve the efficiency of washing the dregs. Through the intelligent control model, the problem of high residual sugar in the inner ring is solved and the quality of washing the dregs is improved. On the other hand, through the reasonable planning of the pipe network structure, the control and regulation of the flow, the control and regulation of the water pressure, and the use of copper pipes and small-angle connections, the smooth circulation of the pipeline can be guaranteed, and the total flow sensor and pressure transmitter can be used to monitor the flow and water pressure in the total filtered water pipeline in real time. Under the joint control of the pressure relief valve and the total flow control valve, the stability of the water pressure and flow rate inside the total filtered water pipeline can be guaranteed, making the distribution of the three-ring flow of the filter tank more convenient.

[0054] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
