Description

TECHNICAL FIELD

[0001] The utility model relates to liquor picking equipment field, concretely is a kind of grading liquor picking equipment. BACKGROUND

[0002] The last procedure of Chinese liquor brewing is distillation liquor picking, and according to liquor flow order, it is divided into liquor head, main liquor and liquor tail, and the main liquor is usually divided into first-grade liquor, second-grade liquor and the like according to alcohol content.

[0003] Different ethanol concentrations have different surface tension bubbles, and in the traditional process, liquor picking is usually carried out according to the size of bubbles, that is, "liquor flower", and the alcohol content is usually judged according to the feeling of employees, resulting in large fluctuation of base liquor grading and poor quality stability. The temperature control in the distillation process also needs to be adjusted in real time by manual, and the liquor temperature fluctuates greatly, so the process stability is poor. At the same time, the whole liquor picking process needs to be checked by employees in real time, and the degree of automation is low, and the labor amount is large. UTILITY MODEL CONTENT

[0004] In view of the above problems, the utility model provides a kind of grading liquor picking equipment, can solve the problem that base liquor picking process needs to be checked by employees in real time and adjusted, resulting in low liquor picking quality and poor stability.

[0005] The grading liquor picking equipment provided by the utility model includes liquor inlet pipeline, condenser, liquor outlet pipeline, liquor head and tail tank, alcohol meter, multiple liquor tanks and switching valve group. The condenser is communicated with the liquor inlet pipeline, and the bottom of the condenser has a base liquor outlet, and the liquor vapor enters the condenser from the liquor inlet pipeline, is condensed into base liquor and then flows out through the base liquor outlet. One end of the liquor outlet pipeline is connected to the base liquor outlet, and the other end is branched to form a first branch and a second branch. The liquor head and tail tank is communicated with the first branch. The alcohol meter is arranged in the second branch. The second branch is further branched to form multiple third branches, and the multiple liquor tanks are respectively communicated with the multiple third branches. The switching valve group is configured to: switch the flow direction of base liquor to the first branch or the second branch, and according to the measurement result of the alcohol meter, switch the base liquor flowing to the second branch to the liquor tank with alcohol content range corresponding to the measurement result.

[0006] Through the above mode, the grading liquor picking equipment provided by the utility model can process liquor head and tail during liquor picking, and the alcohol meter is arranged in the second branch to avoid the interference of ester substances generated by the base liquor in the first branch on the measurement result of the alcohol meter, which is conducive to improving the measurement accuracy of the alcohol meter and improving the accuracy of grading liquor picking. At the same time, the grading liquor picking equipment provided by the utility model saves manual labor and improves the degree of automation of liquor picking.

[0007] Optionally, the switching valve assembly switches the raw liquor flowing into the first branch to the second branch based on a preset time, where the preset time is set based on the raw liquor. In this way, the grading and distillation equipment can initially allow the raw liquor to flow directly into the first branch as the "head" liquor, and then, at the preset time, end the inflow of the head liquor and switch the flow to the second branch. This prevents the head liquor from flowing into the second branch, thus preventing esters in the head liquor from interfering with the alcohol meter's measurement results, improving the accuracy of the alcohol meter, and ultimately enhancing the quality of the distillation process.

[0008] Optionally, when the alcohol meter reading is below the alcohol content range of each tank, the switching valve assembly will switch the raw liquor flowing to the second branch to flow to the first branch. In this way, the grading and distillation equipment can process the tails separately based on the alcohol content of the raw liquor, avoiding interference from the alcohol meter reading and further improving the accuracy of the distillation process.

[0009] Optionally, the switching valve assembly includes multiple control valves connected to the alcohol meter, each corresponding to one of the first, second, and third branches. In this way, the control valves can individually control the first, second, and each third branch, accurately controlling the flow direction of the raw liquor based on the alcohol meter's measurement results.

[0010] Optionally, multiple wine tanks can be arranged sequentially according to their alcohol content range. This orderly arrangement facilitates the switching of the flow of raw wine between adjacent tanks based on the alcohol meter readings.

[0011] Optionally, the condenser has a water inlet, which is equipped with a regulating valve to adjust the flow rate at the water inlet. By controlling the flow rate at the condenser's water inlet using the regulating valve, the condensation process of the raw spirit can be effectively controlled.

[0012] Optionally, the regulating valve is connected to an alcohol meter. In this way, the regulating valve can control the flow rate at the condenser inlet based on the alcohol meter's measurement of the raw liquor flowing through the second branch, further improving the quality and stability of the extracted liquor.

[0013] Optionally, the alcohol meter readings include the alcohol content and temperature of the raw spirit. Measuring the alcohol content and temperature of the raw spirit flowing through the second branch in this way facilitates control over the flow direction of the raw spirit.

[0014] Optionally, the alcohol meter includes an exhaust port. In this way, the alcohol meter expels the gases produced by the measured raw alcohol, reducing interference with the measurement process.

[0015] Optionally, the alcohol meter includes a sensor and a microprocessor. The sensor is connected to the microprocessor, and the microprocessor is connected to the switching valve assembly. In this way, the alcohol meter measures parameters such as the alcohol content and temperature of the raw liquor using the sensor, calculates the alcohol content of the raw liquor using the microprocessor, and sends the alcohol content to the switching valve assembly. This allows the switching valve assembly to control the flow direction of the raw liquor based on its alcohol content. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] <Equipment Composition>

[0021] Figure 1 This is a schematic diagram of the grading and distillation equipment 100 according to an embodiment of this utility model. (Reference) Figure 1 The graded distillation equipment 100 provided in this embodiment includes a condenser 1, an inlet pipe 7, an outlet pipe 2, a head-and-tail tank 3, an alcohol meter 4, multiple tanks 5, and a switching valve assembly 6. The condenser 1 condenses the vapor flowing in from the inlet pipe 7 into raw spirit, which then flows out from the raw spirit outlet 11 at the bottom. During the first distillation, the raw spirit distilled in the first stage flows along the outlet pipe 2 as the head into the head-and-tail tank 3. In the middle stage of distillation, based on the measurement results of the alcohol meter 4, the switching valve assembly 6 can switch the flow of raw spirit in the outlet pipe 2 to the tanks 5 corresponding to the alcohol content range. In the later stage of the first distillation, corresponding to the tail portion, the switching valve assembly 6 can switch the raw spirit flowing to the tanks 5 corresponding to the alcohol content range via the outlet pipe 2 back to the head-and-tail tanks 3.

[0022] The present invention, by setting up an alcohol meter 4 and a switching valve group 6 in cooperation, allows the condensed raw wine to flow through the wine outlet pipe 2 into the head and tail wine tank 3 or the wine tank 5 with the corresponding alcohol content range, thereby realizing the automatic grading and wine extraction of the raw wine, saving manual labor and improving the degree of automation of wine extraction.

[0023] Continue to refer to Figure 1 In this embodiment, the liquor outlet pipe 2 includes a first branch 21, a second branch 22, and a third branch 23. The first branch 21 is connected to the head and tail tanks 3. An alcohol meter 4 is installed on the second branch 22, one end of which is connected to the first branch 21, and the other end is connected to the third branch 23. Multiple third branches 23 are connected to liquor tanks 5 with different alcohol content ranges. When raw liquor begins to flow from the raw liquor outlet 11 of the condenser 1, the switching valve assembly 6 directs the raw liquor as the head into the head and tail tanks 3. After a period of time, the switching valve assembly 6 switches the flow of raw liquor to the second branch 22. After measurement by the alcohol meter 4, the switching valve assembly 6 switches the flow of raw liquor to one of the multiple third branches 23, so that the raw liquor flows into the liquor tank 5 with the corresponding alcohol content range. The switching valve assembly 6 can also switch the raw wine flowing through the third branch 23 to flow into the first branch 21 according to the measurement results of the alcohol meter 4, so that the raw wine flows into the head and tail tank 3 as the tail of the wine.

[0024] This invention, by placing the alcohol meter 4 in the second branch 22 and the head and tail tank 3 in the first branch 21, avoids interference from esters in the raw liquor on the measurement results of the alcohol meter 4. Compared to the prior art where the alcohol meter 4 and the head and tail tank 3 are placed on the same flow path of the outlet pipe 2, this embodiment achieves the processing of the head and tail of the liquor, which is beneficial to improving the measurement accuracy of the alcohol meter 4 and facilitating the improvement of the quality of graded liquor collection.

[0025] The structure of each component of the grading and distillation equipment 100 in this embodiment will be described below.

[0026] <Switching Valve Group 6>

[0027] Continue to refer to Figure 1The switching valve assembly 6 is a device that regulates the flow direction and flow rate of fluid by changing the opening or position of the valves. In this embodiment, the switching valve assembly 6 includes multiple control valves and a control system (not shown). The multiple control valves are communicatively connected to the control system. The multiple control valves include a first control valve 61, a second control valve 62, a third control valve 63, and a fourth control valve 64. The first control valve 61 is located on the first branch 21 so that the control system controls the flow of raw liquor into or out of the head and tail tanks 3. The second control valve 62 is located on the second branch 22 so that the control system receives the measurement results of the raw liquor from the alcohol meter 4. The third control valve 63 is located on the third branch 23 so that the control system controls the flow of raw liquor into or out of the primary tank 51. The fourth control valve 64 is located on the third branch 23 so that the control system controls the flow of raw liquor into or out of the secondary tank 52.

[0028] During a single distillation process, the first distilled spirit flows out from the outlet pipe 2. The control system controls the first control valve 61 to open and the second control valve 62, the third control valve 63 and the fourth control valve 64 to close. The spirit flows as the head into the first branch pipe 21 to the head and tail tank 3.

[0029] In the middle of distillation, the control system closes the first control valve 61 and opens the second control valve 62, while the alcohol meter 4 measures the raw spirit flowing into the second branch 22. The control system receives the measurement results from the alcohol meter 4, including the alcohol content of the raw spirit. When the alcohol content of the raw spirit is within the range of the primary tank 51, the control system opens the third control valve 63 and closes the fourth control valve 64, allowing the raw spirit to flow into the third branch into the primary tank 51. When the alcohol content of the raw spirit is within the range of the secondary tank 52, the control system opens the fourth control valve 64 and closes the third control valve 63, allowing the raw spirit to flow into the third branch into the secondary tank 52.

[0030] In the latter part of the distillation process, when the alcohol content of the raw liquor measured by the alcohol meter 4 is not within the alcohol content range of the first-stage distillation tank 51, nor within the alcohol content range of the second-stage distillation tank 52, the control system controls the second control valve 62, the third control valve 63 and the fourth control valve 64 to close, and the first control valve 61 to open. The raw liquor flows as the tail into the first branch 21 to the head and tail distillation tank 3.

[0031] In the above manner, the control system, based on the measurement results received from the alcohol meter 4, uses the first control valve 61, the second control valve 62, the third control valve 63, and the fourth control valve 64 to individually control the first branch 21, the second branch 22, and each of the third branches 23, thereby accurately controlling the flow direction of the raw liquor.

[0032] Preferably, the switching valve assembly 6 switches the raw wine flowing to the first branch 21 to the second branch 22 based on a preset time, wherein the preset time can be the end time of the head of the wine obtained based on experience or measurement analysis.

[0033] The preset time is not limited here. For example, in some embodiments, the preset time may be an average calculated based on the time when the heads of the spirit were finished during past distillation.

[0034] In this embodiment, the grading and distillation equipment 100 can directly flow the raw liquor as the head into the first branch 21 at the beginning of distillation, and end the flow of the head at a preset time, switching the raw liquor to flow into the second branch 22. This method avoids the head from flowing into the second branch 22, preventing esters in the head from affecting the measurement of the alcohol meter 4, thereby improving the measurement accuracy of the alcohol meter 4.

[0035] Preferably, when the alcohol content of the raw liquor flowing through the third branch 23 is lower than the alcohol content range of all the liquor tanks 5, the switching valve group 6 switches the flow of the raw liquor to the first branch 21, realizing the processing of the tail liquor by the grading and distillation equipment 100. In this way, the esters in the raw liquor, which is the tail liquor, can be avoided from affecting the measurement of the alcohol meter 4, further improving the measurement accuracy of the alcohol meter 4.

[0036] <Alcohol meter 4>

[0037] Continue to refer to Figure 1 The alcohol meter 4 is a digital display alcohol meter 4, a device for real-time detection of parameters such as alcohol content in raw spirits. Alcohol content can be calculated using either the mass percentage method or the volume percentage method. The alcohol meter 4 can calculate alcohol content based on the mass percentage method. The alcohol meter 4 calculates alcohol content by measuring the alcohol concentration of the raw spirit, which is the proportion of the mass of alcohol in the raw spirit to the total mass of the raw spirit. The working principle of the alcohol meter 4 is based on the relationship between alcohol concentration and conductivity. The higher the alcohol concentration of the raw spirit, the higher its conductivity.

[0038] In this embodiment, the alcohol meter 4 includes a built-in sensor (not shown) and a microprocessor (not shown). The sensor can detect the conductivity of the raw wine and transmit the detected conductivity as a signal to the microprocessor. The microprocessor processes the received signal, calculates the alcohol concentration of the raw wine, and thus obtains the alcohol content of the raw wine.

[0039] Preferably, the microprocessor of the alcohol meter 4 is connected to the control system of the switching valve group 6. After calculating the alcohol content of the raw liquor, the microprocessor directly sends the alcohol content and other parameters of the raw liquor to the control system of the switching valve group 6. In this way, the control system can control the opening and closing of the first control valve 61, the second control valve 62, the third control valve 63, and the fourth control valve 64, thereby controlling the flow direction of the raw liquor.

[0040] Preferably, the measurement results of the alcohol meter 4 include the alcohol content and temperature of the raw liquor. In this way, the alcohol meter 4 measures the alcohol content and temperature of the raw liquor flowing through the second branch 22, which facilitates the switching valve group 6 to control the flow direction of the raw liquor.

[0041] Preferably, the alcohol meter 4 includes an exhaust port 41, which is located on the outside of the alcohol meter 4. In this way, the alcohol meter 4 discharges the gas generated by the measured raw alcohol, reducing interference with the measurement process of the alcohol meter 4 and improving the measurement accuracy of the alcohol meter 4.

[0042] <Wine Jar 5>

[0043] Continue to refer to Figure 1 The wine tank 5 is a container for holding the raw wine. In this embodiment, the wine tank 5 includes a primary wine tank 51 and a secondary wine tank 52. The primary wine tank 51 and the secondary wine tank 52 correspond to different alcohol content ranges.

[0044] Preferably, the multiple wine tanks 5 are arranged sequentially according to their alcohol content range. In this embodiment, the primary wine tank 51 is arranged close to the head and tail wine tanks 3, and the secondary wine tank 52 is adjacent to the primary wine tank 51. After the raw wine flows out of the raw wine outlet 11, the head of the raw wine flows into the head and tail wine tanks 3. After the head of the raw wine finishes flowing in, the raw wine flows through the second branch 22 and is measured by the alcohol meter 4. Based on the measurement result of the alcohol meter 4, the switching valve assembly 6 switches the raw wine to flow into either the primary wine tank 51 or the secondary wine tank 52. In this way, the multiple wine tanks 5 are arranged in an orderly manner, which facilitates the switching of the raw wine flow direction between adjacent wine tanks 5 according to the measurement result of the alcohol meter 4.

[0045] In some embodiments, the number of wine jars 5 can be three, four, etc., and the present invention does not limit the number of wine jars 5.

[0046] <Condenser 1>

[0047] Continue to refer to Figure 1 The condenser 1 is a device that converts gas or vapor into liquid. In this embodiment, the condenser 1 converts high-temperature alcohol vapor into liquid liquor by condensing it through a cooling medium. The cooling medium is water.

[0048] Specifically, the condenser 1 has a water inlet 12. When high-temperature alcohol vapor enters the condenser 1, it encounters the water flowing in from the water inlet 12, causing the alcohol vapor to cool rapidly and condense into liquid liquor. The water inlet 12 is equipped with a regulating valve 121. The regulating valve 121 can adjust the flow rate of the water inlet 12, thereby controlling the flow rate of the cooling water and facilitating the control of the liquor condensation process.

[0049] Preferably, the regulating valve 121 is connected to the alcohol meter 4. The microprocessor of the alcohol meter 4 sends the measured temperature of the raw liquor to the regulating valve 121, which adjusts the flow rate of the water inlet 12 based on the temperature of the raw liquor. In this way, the grading and distillation equipment 100 can control the flow rate of the water used for condensation through the regulating valve 121, thereby controlling the condensation process of the raw liquor and further improving the quality and stability of the distillation.

[0050] The following is combined Figure 1 This describes the working process of the grading and distillation equipment 100 in this embodiment.

[0051] Alcohol vapor flows into condenser 1 from inlet pipe 7 and condenses into raw liquor, which then flows out from raw liquor outlet 11. Switching valve assembly 6 controls the flow of raw liquor along outlet pipe 2 to the first branch 21, where it flows as the head and tail of liquor into the head and tail tank 3. After a period of time, switching valve assembly 6 switches the flow of raw liquor to the second branch 22, allowing alcohol meter 4 to measure the alcohol content and temperature of the raw liquor.

[0052] When the alcohol content of the raw liquor is within the range of the primary tank 51, the switching valve assembly 6 switches the flow of the raw liquor to the third branch 23 connected to the primary tank 51, so that the raw liquor flows into the primary tank 51. When the alcohol content of the raw liquor is within the range of the secondary tank 52, the switching valve assembly 6 switches the flow of the raw liquor to the third branch 23 connected to the secondary tank 52, so that the raw liquor flows into the secondary tank 52. When the alcohol content of the raw liquor is neither within the range of the primary tank 51 nor within the range of the secondary tank 52, the switching valve assembly 6 switches the raw liquor flowing through the third branch 23 to flow through the second branch 22 to the first branch 21, so that the raw liquor flows as the tail end into the head and tail tank 3.

[0053] This utility model also provides a method for graded wine extraction, including the following steps S1-S4.

[0054] Step S1: The alcohol vapor enters the condenser from the inlet pipe, condenses into raw liquor, and then flows out from the raw liquor outlet.

[0055] Step S2: Switch the valve group to control the flow of raw liquor through the raw liquor outlet to the first branch on the liquor outlet pipeline, so that the head of the raw liquor enters the head and tail tank.

[0056] Step S3: At a preset time, the switching valve group controls the flow of raw wine to the second branch on the wine outlet pipeline so that the raw wine is measured by the alcohol meter. The alcohol meter sends the measurement result to the switching valve group, and the switching valve group switches the flow of raw wine to the wine tank in the corresponding alcohol meter range on the third branch based on the measurement result.

[0057] Step S4: When the alcohol meter reading exceeds the alcohol content range of each tank, the switching valve group switches the flow direction of the raw liquor so that the tail of the raw liquor flows through the second branch to the head and tail tanks on the first branch.

[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
