[0033] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0034] As Figure 1 shown, a specific implementation manner of the beverage quality detection device based on double conductivity provided in this embodiment includes: a to-be-filled can 1, a filling machine 2, and a conductivity detection component 4. The inside of the to-be-filled can 1 is adapted to accommodate the liquid material. The feed inlet of the filling machine 2 is connected to the to-be-filled can 1 through a conveying pipeline 3. The conductivity detection component 4 is installed on the to-be-filled can 1 and / or the conveying pipeline 3. The conductivity detection component 4 has a probe for detecting the conductivity of the liquid material. In this embodiment, the liquid material can be walnut milk. In order to make the production process more complete, a seaming machine 21 can also be added in the next process of the filling machine 2.
[0035] The beverage quality detection device based on dual conductivity provided by this embodiment detects the conductivity of the liquid material through the conductivity detection component 4. When the liquid material enters the water, the water content increases, which will cause the conductivity of the liquid material to decrease. The detected value has a direct relationship with the water content and is not affected by the properties of the liquid material itself. By the change of conductivity, it can be judged whether the quality of the liquid material meets the standard, and the detection result is more obvious.
[0036] As Figure 1 shown, in the beverage quality detection device based on dual conductivity provided by this embodiment, the conductivity detection component 4 includes: a first conductivity meter 5 and a second conductivity meter 6. The first conductivity meter 5 is installed on the can to be filled 1, and the second conductivity meter 6 is installed on the conveying pipeline 3. The first conductivity meter 5 and the second conductivity meter 6 can detect the liquid material at different positions, and measure the change of the conductivity of the liquid material in each link in real time, with a wider detection range, which is convenient for timely discovering the liquid material with unqualified quality. Of course, the above description is not restrictive. In some alternative embodiments, only one conductivity detection component 4 can be provided. For example, only the first conductivity meter 5 can be provided, or only the second conductivity meter 6 can be provided, etc.
[0037] As Figure 1 、 Figure 2 shown, in the beverage quality detection device based on dual conductivity provided by this embodiment, the first conductivity meter 5 is an inductive conductivity meter, which is arranged on the side of the can to be filled 1. The inductive conductivity meter is suitable for detecting the static liquid material. Specifically, the working principle of the inductive conductivity meter is based on the inverse relationship between the conductivity of the liquid and the inductance of the impedance element in the liquid. The conductivity is measured by using the principle of alternating current electromagnetic induction. When the liquid flow rate is too low or in a static state, the current change in the induction coil is more stable, so that a more accurate induced electromotive force can be generated. According to Ohm's law, a more accurate conductivity value can be measured. The volume of the can to be filled 1 is large, and the flow rate of the liquid material inside is slow. Therefore, the probe of the inductive conductivity meter is fully in contact with the liquid material, and the detection effect is better.
[0038] As Figure 1 、 Figure 3As shown in the figure, in the beverage quality detection device based on dual conductivity provided in this embodiment, the second conductivity meter 6 is an electrode-type conductivity meter, which is arranged at the corner of the conveying pipeline 3. The water inlet of the electrode-type conductivity meter faces the upstream pipeline, and the water outlet of the electrode-type conductivity meter faces the downstream pipeline. The liquid can directly wash the probe without accumulation. The electrode-type conductivity meter is suitable for detecting dynamic liquid. Specifically, the working principle of the electrode-type conductivity meter is to determine the conductivity by measuring the conductivity of the solution between the electrodes. In dynamic liquid, the contact between the electrode and the solution is more frequent and dynamic, which helps the electrode to more accurately sense the change of ion concentration in the solution. The diameter of the conveying pipeline 3 is small, and the flow rate of the liquid inside is fast. Therefore, the probe of the electrode-type conductivity meter is fully in contact with the liquid, ensuring the detection effect, and can also eliminate the influence of bubbles and avoid the aggregation of solid particles.
[0039] As Figure 1 shown in the figure, in the beverage quality detection device based on dual conductivity provided in this embodiment, it further includes: a display instrument 7, electrically connected to the conductivity detection component 4. The display instrument 7 can display the value detected by the conductivity detection component 4, which is convenient for the staff to observe and control.
[0040] As Figure 1 shown in the figure, in the beverage quality detection device based on dual conductivity provided in this embodiment, an air control valve 8 is provided on the conveying pipeline 3. The air control valve 8 is electrically connected to the controller 9, and the controller 9 is electrically connected to the conductivity detection component 4. The controller 9 controls the opening or closing of the air control valve 8 according to the signal of the conductivity detection component 4, realizing automatic processing. There is no need for manual closing of the valve, the processing speed is faster, and the degree of automation is higher. Specifically, the controller 9 can be a PLC control cabinet.
[0041] As Figure 1 shown in the figure, in the beverage quality detection device based on dual conductivity provided in this embodiment, the air control valve 8 includes: a first valve 10, a second valve 11 and a seventh valve 22. The first valve 10 is located at the discharge port of the tank to be filled 1, the second valve 11 is located at the feed port of the filling machine 2, and the seventh valve 22 is located at the discharge port of the transfer pump 23 on the conveying pipeline 3. The first valve 10 is used to prevent the liquid in the tank to be filled 1 from flowing into the conveying pipeline 3 continuously, the second valve 11 is used to prevent the liquid in the conveying pipeline 3 from flowing into the filling machine 2 continuously, and the seventh valve 22 is used to prevent the liquid in the conveying pipeline 3 from flowing downward continuously. Under the combined action of the first valve 10, the second valve 11 and the seventh valve 22, multiple barriers are formed for the liquid, and the barrier effect on the liquid is better. Of course, the above description is not restrictive. In some alternative embodiments, only one air control valve 8 may be provided. For example, only the first valve 10 may be provided, or only the second valve 11 may be provided, or only the seventh valve 22 may be provided, etc.
[0042] like Figure 1 As shown, in the beverage quality detection device based on dual conductivity provided in this embodiment, the can to be filled 1 has a feeding pipe 12, and a third valve 13 is arranged on the feeding pipe 12. The discharge port of the feeding pipe 12 faces the side wall of the can to be filled 1. The liquid feed enters the can to be filled 1 through the feeding pipe 12, flows from the discharge port of the feeding pipe 12 to the side wall of the can to be filled 1, and continues to flow downward along the side wall of the can to be filled 1. The side wall of the can to be filled 1 guides and buffers the liquid feed, thereby avoiding splashing of the liquid feed in the can to be filled 1 and improving the stability and quietness of the equipment during operation. The third valve 13 controls the flow of the liquid feed. When the liquid feed is not needed, the third valve 13 can be closed.
[0043] like Figure 1 As shown, the beverage quality detection device based on dual conductivity provided in this embodiment also includes: a first cleaning pipe 14, which is connected to the inside of the can 1 to be loaded, and a fourth valve 15 is arranged on the first cleaning pipe 14. The first cleaning pipe 14 has a plurality of water outlets arranged at intervals along the height direction, and the plurality of water outlets are all directed toward the agitator 16 in the can 1 to be loaded. The first cleaning pipe 14 is suitable for the flow of cleaning liquid, so as to clean the inner wall of the can 1 to be loaded. The plurality of water outlets make the spraying range of the cleaning liquid larger, and the cleaning liquid will pass through the agitator 16 and then fly to the inner wall of the can 1 to be loaded. The flow effect of the cleaning liquid is better, and the corresponding cleaning effect is also better. The fourth valve 15 controls the flow of the cleaning liquid. When the cleaning liquid is not needed, the fourth valve 15 can be closed.
[0044] like Figure 1 As shown, the beverage quality detection device based on dual conductivity provided in this embodiment also includes: a second cleaning pipe 17, which is connected to the corner of the conveying pipe 3 near the can 1 to be loaded, and a fifth valve 18 is provided on the second cleaning pipe 17. The water outlet of the second cleaning pipe 17 faces the pipe located downstream, and the second cleaning pipe 17 is suitable for the cleaning liquid to flow into, so as to clean the conveying pipe 3 located downstream, and the pipe located upstream is cleaned by the cleaning liquid in the can 1 to be loaded. The second cleaning pipe 17 can input the cleaning liquid from one end of the conveying pipe 3, which has a better cleaning effect on the conveying pipe 3, and the space at the corner is larger, and the installation is more convenient. The fifth valve 18 controls the flow of the cleaning liquid. When the cleaning liquid is not needed, the fifth valve 18 can be closed. The corner of the conveying pipe 3 near the can 1 to be loaded is connected to a drainage pipe 19, and the drainage pipe 19 is provided with a sixth valve 20. When drainage is required, the sixth valve 20 and the first valve 10 are opened, and the cleaning liquid is directly discharged to the ditch through the drainage pipe 19. When the cleaning liquid does not need to be discharged, the sixth valve 20 can be closed.
[0045] Usage method of the beverage quality detection device based on dual conductivity provided by this embodiment:
[0046] First, input the liquid material into the can to be filled 1. The liquid material flows along the conveying pipeline 3 to the filling machine 2. During the flow of the liquid material, the electrode conductivity meter and the inductive conductivity meter simultaneously detect the conductivity of the liquid material. The normal value of the conductivity of the liquid material is 800 - 1000 / μs / cm. According to the liquid material conductivity = V1 ÷ (V1 + V2) * 1000, where V1 is the volume of the liquid material, V2 is the volume of water, and 1000 is the normal value of the conductivity of the liquid material. When water enters the liquid material, at this time V2 increases and other factors remain unchanged, resulting in a decrease in the value of the conductivity of the liquid material. Thus, it can be concluded that water has entered the liquid material. When the measured conductivity is lower than the set lower limit of 800 / μs / cm, the controller 9 sends a signal to close the first valve 10, the second valve 11, and the seventh valve 22, timely block the flow of the liquid material, and turn off the transfer pump 23, the filling machine 2, and the seaming machine 21 for shutdown inspection and maintenance.
[0047] Obviously, the above embodiments are merely examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
