Description

Technical Field

[0001] The invention relates to the field of wine picking equipment, in particular to a classification wine picking equipment. Background Art

[0002] The last step in the Chinese liquor brewing process is distillation. The order of liquor flow is head liquor, main liquor and tail liquor. The main liquor is usually divided into first-grade liquor, second-grade liquor, etc. according to the alcohol content.

[0003] Different ethanol concentrations produce different bubbles due to surface tension. In traditional processes, wine is usually picked based on the size of the bubbles, or "hops". The alcohol content is usually judged based on the employees' feelings, resulting in large fluctuations in the classification of the original wine and poor quality stability. The temperature control during the distillation process also requires manual real-time adjustment, resulting in large fluctuations in the flow temperature and poor process stability. At the same time, the entire wine picking process requires real-time monitoring by employees, with a low degree of automation and a large workload. Summary of the invention

[0004] In view of the above problems, the present invention provides a grading wine picking device, which can solve the problem that the raw wine picking process needs to be checked and adjusted by employees in real time, resulting in low wine picking quality and poor stability.

[0005] The grading wine picking equipment provided by the present invention includes a condenser, a wine outlet pipeline, a head and tail wine tank, an alcohol meter, a plurality of wine tanks and a switching valve group. The condenser has a raw wine outlet, and the wine vapor enters the condenser and condenses into raw wine and then flows out through the raw wine outlet. One end of the wine outlet pipeline is connected to the raw wine outlet, and the other end branches to form a first branch and a second branch. The head and tail wine tanks are connected to the first branch. The alcohol meter is arranged in the second branch.

[0006] Through the above methods, the grading wine picking equipment provided by the present invention can process the head and tail of the wine when picking the wine. The alcohol meter is set to cooperate with the switching valve group, so that the head of the wine can be processed at the beginning of the wine picking, and the tail of the wine can be processed according to the measurement result of the alcohol meter, thereby improving the quality and stability of the wine picking. At the same time, the grading wine picking equipment provided by the present invention saves manpower and improves the degree of automation of wine picking. And the alcohol meter is set in the second branch to avoid the ester substances produced by the original wine in the first branch from interfering with 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 wine picking.

[0007] Optionally, the switching valve group switches the raw wine flowing to the first branch to flowing to the second branch based on a preset time, wherein the preset time is set based on the raw wine. In the above manner, the grading wine picking device can directly flow the raw wine as the head of wine into the first branch at the beginning of wine picking, and end the flow of the head of wine at the preset time, and switch the raw wine to flow to the second branch, thereby avoiding the head of wine from flowing into the second branch, preventing the ester substances in the head of wine from interfering with the measurement results of the alcohol meter, which is beneficial to the measurement accuracy of the alcohol meter, thereby improving the quality of wine picking.

[0008] Optionally, when the measurement result of the alcohol meter is lower than the alcohol content range of each wine tank, the switching valve group switches the raw wine flowing to the second branch to flow to the first branch. In the above manner, the graded wine picking device can process the tail wine separately based on the alcohol content of the raw wine, avoid the tail wine from interfering with the measurement of the alcohol meter, and further improve the accuracy of wine picking.

[0009] Optionally, the switching valve group includes a plurality of control valves connected to the alcohol meter, and each control valve corresponds to the first branch, the second branch, and the third branch. In the above manner, the control valve can realize separate control of the first branch, the second branch, and each third branch, and accurately control the flow direction of the original wine according to the measurement result of the alcohol meter.

[0010] Optionally, the plurality of wine tanks are arranged in sequence according to the alcohol content range. In the above manner, the plurality of wine tanks are arranged in an orderly manner, so that the flow direction of the original wine can be switched between two adjacent wine tanks according to the measurement result of the alcohol meter.

[0011] Optionally, the condenser has a water inlet, and the water inlet is provided with a regulating valve, and the regulating valve is used to adjust the flow of the water inlet. In the above manner, the flow of the water inlet of the condenser is controlled by the regulating valve, which is convenient for controlling the condensation process of the original wine.

[0012] Optionally, the regulating valve is connected to an alcohol meter. In the above manner, the regulating valve can control the flow rate of the water inlet of the condenser according to the measurement result of the alcohol meter on the raw wine flowing through the second branch, thereby further improving the quality and stability of wine picking.

[0013] Optionally, the measurement result of the alcohol meter includes the alcohol content and temperature of the original wine.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] <Equipment Composition>

[0021] Figure 1 Schematic diagram of the structure of the wine grading and picking device 100 in the embodiment of the present invention. Figure 1 The grading wine picking equipment 100 provided in this embodiment includes a condenser 1, a wine outlet pipeline 2, a head and tail wine tank 3, an alcohol meter 4, a plurality of wine tanks 5 and a switching valve group 6. Among them, after the condenser 1 condenses the incoming wine vapor into raw wine, the raw wine flows out from the raw wine outlet 11. During a single distillation process, the raw wine distilled in the first section flows along the wine outlet pipeline 2 and first flows into the head and tail wine tank 3 as the head wine. In the middle stage of the distillation, according to the measurement result of the alcohol meter 4, the switching valve group 6 can switch the raw wine in the wine outlet pipeline 2 to flow into the wine tank 5 of the corresponding alcohol content range. In the latter stage of the single distillation process, corresponding to the tail part of the wine, the switching valve group 6 can switch the raw wine flowing to the wine tank 5 of the corresponding alcohol content range to the head and tail wine tank 3 via the wine outlet pipeline 2.

[0022] The embodiment of the present invention cooperates with the alcohol meter 4 and the switching valve group 6 to allow the condensed raw wine to flow through the wine outlet pipeline 2 into the head and tail tanks 3 or the wine tanks 5 corresponding to the alcohol content range, thereby realizing automatic grading and picking of the raw wine, saving human labor, and thus improving the degree of automation of wine picking.

[0023] Continue to refer Figure 1 In this embodiment, the wine outlet pipeline 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 arranged on the second branch 22, one end of the second branch 22 is connected to the first branch 21, and the other end is connected to the third branch 23. The plurality of third branches 23 are respectively connected to wine tanks 5 with different alcohol content ranges. When the raw wine outlet 11 of the condenser 1 starts to flow out the raw wine, the switching valve group 6 flows the raw wine as the head into the head and tail tanks 3. After a period of time, the switching valve group 6 switches the raw wine to flow to the second branch 22. After being measured by the alcohol meter 4, the switching valve group 6 switches the raw wine to flow to one of the plurality of third branches 23, so that the raw wine flows to the wine tank 5 with the corresponding alcohol content range. The switching valve group 6 can also switch the original 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 original wine flows into the head and tail tanks 3 as the tail.

[0024] The embodiment of the present invention prevents the ester substances in the original wine from interfering with the measurement result of the alcohol meter 4 by setting the alcohol meter 4 in the second branch 22 and the head and tail tank 3 in the first branch 21. Compared with the prior art in which the alcohol meter 4 and the head and tail tank 3 are set on the wine outlet pipeline 2 with the same flow direction, this embodiment realizes the processing of the head and tail of the wine, which is conducive to improving the measurement accuracy of the alcohol meter 4 and facilitating the improvement of the quality of graded wine picking.

[0025] The structures of the various components of the wine grading and picking equipment 100 in this embodiment are introduced below.

[0026] <Switch valve group 6>

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

[0028] During a distillation process, the raw wine distilled in the first stage flows out from the wine outlet pipeline 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, and the raw wine flows into the first branch 21 as the head wine to the head and tail wine tank 3.

[0029] In the middle of the distillation, the control system controls the first control valve 61 to close, the second control valve 62 to open, and the alcohol meter 4 measures the raw wine flowing into the second branch 22. The control system receives the measurement results from the alcohol meter 4, which include the alcohol content of the raw wine. When the alcohol content of the raw wine is within the alcohol content range of the primary wine tank 51, the control system controls the third control valve 63 to open, the fourth control valve 64 to close, and the raw wine flows into the third branch to the primary wine tank 51. When the alcohol content of the raw wine is within the alcohol content range of the secondary wine tank 52, the control system controls the fourth control valve 64 to open, the third control valve 63 to close, and the raw wine flows into the third branch to the secondary wine tank 52.

[0030] In the latter part of a distillation process, when the alcohol content of the original wine measured by the alcohol meter 4 is neither within the alcohol content range of the first wine tank 51 nor within the alcohol content range of the secondary wine 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, and the original wine flows into the first branch 21 as tail wine into the head and tail wine tank 3.

[0031] In the above manner, the control system realizes individual control of the first branch 21, the second branch 22 and each third branch 23 through the first control valve 61, the second control valve 62, the third control valve 63 and the fourth control valve 64 respectively according to the measurement results of the received alcohol meter 4, thereby accurately controlling the flow direction of the raw wine.

[0032] Preferably, the switching valve group 6 switches the original wine flowing to the first branch 21 to flowing to the second branch 22 based on a preset time, wherein the preset time may be the time when the head of the wine ends obtained based on experience or measurement analysis.

[0033] The preset time is not limited here. For example, in some embodiments, the preset time can be an average calculated based on the time when the head of the wine ends during the past distillation of the original wine.

[0034] In this embodiment, the grading wine picking device 100 can directly flow the original wine as the head wine into the first branch 21 at the beginning of wine picking, and end the flow of the head wine at a preset time, and switch the original wine to flow to the second branch 22. In the above manner, it is possible to prevent the head wine from flowing into the second branch 22, prevent the ester substances in the head wine from affecting the measurement of the alcohol meter 4, and thus improve the measurement accuracy of the alcohol meter 4.

[0035] Preferably, when the alcohol content of the original wine flowing through the third branch 23 is lower than the alcohol content range of all wine tanks 5, the switching valve group 6 switches the original wine to flow to the first branch 21, so that the wine grading and picking device 100 can process the wine tail. In the above manner, it is possible to avoid the ester substances in the original wine as the wine tail affecting the measurement of the alcohol meter 4, and further improve the measurement accuracy of the alcohol meter 4.

[0036] <Alcohol Meter 4>

[0037] Continue to refer Figure 1 The alcohol meter 4 is a digital alcohol meter 4, which is a device for real-time detection of parameters such as the alcohol content of the original wine. The calculation of the alcohol content can be performed by the mass percentage method or the volume percentage method. The alcohol meter 4 can calculate the alcohol content based on the mass percentage method. The alcohol meter 4 calculates the alcohol content by measuring the alcohol concentration of the original wine, and the alcohol concentration is the ratio of the mass of alcohol in the original wine to the total mass of the original wine. The working principle of the alcohol meter 4 is based on the relationship between alcohol concentration and conductivity. When the alcohol concentration of the original wine is higher, the conductivity of the original wine is higher.

[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 original wine and transmit the detected conductivity as a signal to the microprocessor. The microprocessor processes the received signal, calculates the alcohol concentration of the original wine, and then obtains the alcohol content of the original 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 original wine, the microprocessor directly sends the parameters such as the alcohol content of the original wine to the control system of the switching valve group 6. In the above manner, 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 original wine.

[0040] Preferably, the measurement result of the alcohol meter 4 includes the alcohol content and temperature of the original wine. In the above manner, the alcohol meter 4 measures the alcohol content and temperature of the original wine flowing through the second branch 22, so that the switching valve group 6 can control the flow direction of the original wine.

[0041] Preferably, the alcohol meter 4 includes an exhaust port 41, which is disposed outside the alcohol meter 4. In the above manner, the alcohol meter 4 exhausts the gas generated by the measured original wine, reduces interference with the measurement process of the alcohol meter 4, and improves the measurement accuracy of the alcohol meter 4.

[0042] <Wine Tank 5>

[0043] Continue to refer Figure 1 The wine tank 5 is a container for holding 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, multiple wine tanks 5 are arranged in sequence according to the alcohol content range. In this embodiment, the first-level wine tank 51 is arranged close to the head and tail tanks 3, and the second-level wine tank 52 is adjacent to the first-level wine tank 51. When the raw wine flows out from the raw wine outlet 11, the head of the raw wine flows into the head and tail 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. The switching valve group 6 switches the raw wine to flow into the first-level wine tank 51 or the second-level wine tank 52 based on the measurement results of the alcohol meter 4. In the above manner, multiple wine tanks 5 are arranged in an orderly manner, which facilitates the switching of the raw wine flow direction between two adjacent wine tanks 5 according to the measurement results of the alcohol meter 4.

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

[0046] <Condenser 1>

[0047] Continue to refer Figure 1 The condenser 1 is a device for converting gas or vapor into liquid. In this embodiment, the condenser 1 condenses the high-temperature wine vapor through a cooling medium to convert the wine vapor into liquid original wine. The cooling medium is water.

[0048] Specifically, the condenser 1 has a water inlet 12. After the high-temperature wine vapor enters the condenser 1, it encounters the water flow flowing in from the water inlet 12, and the wine vapor is quickly cooled and condensed into liquid raw wine. The water inlet 12 is provided with a regulating valve 121. The regulating valve 121 can adjust the flow of the water inlet 12, thereby controlling the flow of the water flow used for cooling, which is convenient for controlling the condensation process of the raw wine.

[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 wine to the regulating valve 121, and the regulating valve 121 adjusts the flow rate of the water inlet 12 based on the temperature of the raw wine. In the above manner, the grading wine picking device 100 can control the flow rate of the water flow used for condensation through the regulating valve 121, thereby controlling the condensation process of the raw wine, and further improving the quality and stability of wine picking.

[0050] Combine the following Figure 1 , to describe the working process of the grading and picking wine equipment 100 in this embodiment.

[0051] The wine vapor flows into the condenser 1 and condenses into raw wine, which flows out from the raw wine outlet 11. The switching valve group 6 controls the raw wine to flow along the wine outlet pipeline 2 to the first branch 21, and the raw wine flows into the head and tail tanks 3 as the head of the wine. After a period of time, the switching valve group 6 switches the raw wine to flow to the second branch 22, so that the alcohol meter 4 can measure the alcohol content and temperature of the raw wine.

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

[0053] The present invention also provides a method for grading wine, comprising the following steps S1-S4.

[0054] Step S1: After the wine vapor enters the condenser and condenses into raw wine, it flows out from the raw wine outlet.

[0055] Step S2: The switching valve group controls the raw wine to flow to the first branch of the wine outlet pipeline, so that the head of the raw wine enters the head and tail tanks.

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

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

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