Description

Technical Field

[0001] The utility model relates to the technical field of beer brewing, and in particular to a precise adding system for beer additives. Background Art

[0002] The saccharification stage of beer brewing mainly includes gelatinization, saccharification, boiling and other stages. Five kinds of material additives need to be added to each batch of wort, and the amount of each additive added varies greatly, ranging from tens of grams to 40 kilograms. All additives are weighed manually using a measuring scale and a measuring cup.

[0003] Disadvantages of current technology:

[0004] Manual weighing has the risk of human error and measurement deviation control, which is not conducive to maintaining the stability of the quality and flavor consistency of each batch of wort. In the wort production process, if there are inaccurate manual weighing, omissions, wrong additions, or additives dumped, there will be a lot of residue on the inner wall of the container, resulting in a reduction in the amount of addition, which in turn affects the accuracy of addition and ultimately affects the stability of the wort quality. In severe cases, the wort cannot be gelatinized or the substances in the saccharification process are decomposed normally, causing major quality accidents.

[0005] During the wort preparation process, the amount of additives added is recorded manually using the corresponding key information of the additives. However, this method is difficult to avoid "recording errors" and other situations. Although there is synchronous traceability of the ERP system, the operation of human factors is not conducive to the search and analysis of the real cause of abnormal batches.

[0006] During the adding process, additives are weighed manually, and the materials are transferred to open barrels through weighing instruments and then transported to the production site in batches. There is a time difference in adding, which greatly increases the risk of contamination and increases the difficulty of maintaining hygiene of instruments, transfer vehicles and the ground during transportation.

[0007] Therefore, in view of the deficiencies in the prior art, a precise adding system for beer additives is provided. Utility Model Content

In addition, the descriptions of up, down, left, right, etc. used in the present invention are only relative to the relative positional relationship of the components of the present invention in the accompanying drawings.

[0039] Reference Figure 1 , a precise adding system for beer additives, comprising a liquid storage tank 1, a dilution tank 5, a metering group, a conveying pipeline and a detection mechanism, wherein the metering group is connected to the detection mechanism;

[0040] In one embodiment, the metering group includes a first metering scale 2, a metering pump 3 and a second metering scale 4; the delivery pipeline includes a first pipeline 6; the first pipeline 6 connects the liquid storage tank 1 and the dilution tank 5; the first metering scale 2 is located below the liquid storage tank 1 to weigh the weight of the liquid storage tank 1; the metering pump 3 and the second metering scale 4 are both located at the first pipeline 6, and the second metering scale 4 is located at the rear end of the metering pump 3. The second metering scale 4 controls the rotation speed of the metering pump 3 through a detection mechanism and accurately controls the flow rate of the metering pump 3. The first metering scale 2 and the second metering scale 4 are automatically read and calibrated through the detection mechanism.

[0041] Among them, a systematic online precise addition system for beer additives is established, which includes a first metering scale 2, a metering pump 3, a second metering scale 4 and a corresponding detection mechanism. The first metering scale 2 is located below the liquid storage tank 1 to weigh the weight of the liquid storage tank 1, and the second metering scale 4 is located at the rear end of the metering pump 3. The second metering scale 4 controls the speed of the metering pump 3 through the detection mechanism and accurately controls the flow of the metering pump 3. The first metering scale 2 and the second metering scale 4 are automatically read and aligned through the detection mechanism. The metering pump speed is controlled according to the viscosity and other characteristics of the added material to achieve precise weighing, and the second pH meter is used for auxiliary monitoring of the addition to comprehensively improve the accuracy of the amount of additives added, avoid human operational errors, and thus ensure that the variety and quantity of additives are precisely controlled, eliminate the phenomenon of missing addition, wrong addition, and large error deviation of the amount of addition between batches of wort, and improve the quality stability and flavor consistency of each batch of wort. This precise addition system for beer additives has the characteristics of precise addition of additives.

[0042] In one embodiment, the precision addition system further includes a working pot group, which includes a gelatinization pot 11, a saccharification pot 12 and a boiling pot, and the gelatinization pot 11, the saccharification pot 12 and the boiling pot are independent of each other. The material configuration specialist regularly allocates the reserve of additives according to the planned amount every day. Before adding additives and leaving the warehouse, the system will identify the materials and record the material warehouse location (for materials with multiple exits). If the original purpose of the addition unit is changed, manual confirmation is required.

[0043] In one embodiment, the delivery pipeline further includes a second pipeline 7, and the second pipeline 7 connects the dilution tank 5 and the working pot group. Preferably, a stirrer 51 is provided inside the dilution tank 5. Preferably, after the second weighing scale 4 weighs the target required amount of material mother liquor, it is placed in the dilution tank 5 for temporary storage and dilution of the quantitative material addition mother liquor, and is stirred evenly by the stirrer 51 provided inside the dilution tank 5. After the material mother liquor is diluted, its viscosity is reduced, which can effectively reduce the loss caused by the wall attachment in the addition pipeline system, and further accurately control the addition amount.

[0044] In one embodiment, the metering group further comprises an output pump 8, a flow meter 9 and a first pH meter 10, which are sequentially arranged on the second pipeline 7 along the material flow direction. Preferably, the output pump 8 is a stainless steel centrifugal pump.

[0045] In one embodiment, the metering group also includes a reversing valve 13 and a second pH meter 14. The gelatinization pot 11, the saccharification pot 12 and the boiling pot are all provided with a reversing valve 13 and a second pH meter 14; the reversing valve 13 is connected to the second pipeline 7, and the second pH meter 14 is located at the rear end of the reversing valve 13. The properties of the substance are detected by the second pH meter to prevent valve leakage from causing the wrong addition of varieties.

[0046] In one embodiment, the first metering scale 2, the second metering scale 4 and the metering pump 3 are all connected to the detection mechanism, and the second metering scale 4 is located at the front end of the dilution tank 5; the first metering scale 2 is a platform scale; the second metering scale 4 is a high-precision metering scale; and the metering pump 3 is a silicone hose pump. Preferably, the metering data of the first metering scale 2 is transmitted to the detection mechanism in real time during the configuration and addition process, and the detection mechanism automatically reads and records the metering data, and sets the feeding control parameters in the program to realize online short-interval monitoring and automatic alarm control. Preferably, the metering pump 3 and the second metering scale 4 match the metering parameters of the dilution tube to ensure the second step of accurate addition of the system. Because the addition amount of the additive ranges from tens of grams to tens of kilograms, each dilution tank 5 in the system is equipped with a corresponding metering pump 3. Different additives are controlled by setting the speed and advance amount of the metering pump 3 according to their addition amount and the viscosity of the material itself, and different materials, different flows, and different speed curves are controlled, while taking into account the addition speed and metering accuracy, further consolidating the accurate control of the addition amount of the system. The second metering scale 4 is located at the inlet end of the dilution tank 5 , which is a key step to achieve precise control of the system. The material is extracted from the liquid storage tank 1 through the metering pump 3 , and is accurately weighed by the second metering scale 4 and then sent to the dilution tank 5 .

[0047] Similarly, in order to meet the need for liquid replenishment and weigh a large amount, the first weighing scale 2 has a larger range, and its accuracy is not as good as the second weighing scale 4. However, both can realize automatic reading and calibration of single and cumulative weighing data. When the cumulative reduction of the material on the first weighing scale 2 after each addition is compared with the cumulative amount of the data on the second weighing scale 4, when there is a large deviation between the cumulative quantities of the two, the system will promptly alarm, which is convenient for process technicians to calibrate and repair the weighing system.

[0048] Preferably, the second metering scale 4 controls the speed of the metering pump 3; when the metering weighing is in the initial stage, the second metering scale 4 controls the metering pump 3 to adopt a high speed and large flow rate through the detection mechanism; when the metering weighing is close to the target value, the second metering scale 4 controls the metering pump 3 to adopt a low speed and small flow rate through the detection mechanism. The metering pump 3 can set the control parameters matching it according to the characteristics such as the addition amount and viscosity of the material to control the speed of the liquid entering the metering scale. The metering pump 3 starts the initial stage with a high speed and a large flow rate to achieve a large amount of rapid addition and reduce the addition time. The final stage adopts a low speed and a small flow rate to achieve a micro-precise control of the deviation between the actual addition value and the target value. The speed time change is controlled by the second metering scale 4 through the detection mechanism feedback. The system also monitors the single addition time of the metering pump 3, and an alarm prompts when there is a significant deviation. The second metering scale 4 dynamically sets the target weighing value according to the process formula, and the increment in the weighing process reversely controls the speed of the metering pump 3. When it is close to the target amount, the speed of the metering pump 3 is reduced to reduce the deviation and improve the measurement accuracy.

[0049] In one embodiment, the second pipe 7 is communicated with the lower end of the dilution tank 5 .

[0050] In one embodiment, the first pH meter 10 further consolidates the accuracy of material addition to avoid mis-addition, wrong addition and leakage. Different additives are equipped with a "pH meter" on the pipe at the entrance of the addition point, and the automatic monitoring data in the computer during online addition is used to make a preliminary judgment on whether the material is mis-added at a non-target addition point or whether there is leakage in the "reversing valve 13"; at the same time, the second pH meter 14 is used as a top water control signal in the system.

[0051] In the system, the automatic weighing process will automatically generate a record report, including date, time, wort batch, additive production batch and date, added amount, etc. It can be archived according to variety, date, batch and other information for traceability analysis.
