It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0041] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0043] The plum wine production system proposed in the present invention is described by taking the preparation of green plum wine as an example. It is easy for those skilled in the art to understand that in order to apply the design of the plum wine production system to the design of preparing other types of extracted wines, various modifications, additions, substitutions, deletions or other changes are made to the specific embodiments described below, and these changes are still within the scope of the principle of the plum wine production system proposed in the present invention.

[0044] See also Figure 1As shown, the plum wine production system according to the embodiment of the present invention includes a feeding unit 10, a wine feeding unit 20, an extraction unit 30, a sugar dissolving unit 40, a freezing unit 50, a centrifugal unit 60 and a wine discharging unit 70.

[0045] like Figure 1 As shown, the feeding unit 10 includes a screening platform 11, a cleaning tank 12 and a feeding device 13. The screening platform 11 is used to screen the green plum raw materials. For example, the screening platform 11 may include a frame and a tray, and the tray is arranged on the top of the frame. The tray is used to hold the green plums for the convenience of workers. At the screening platform 11, workers can screen the fresh green plums and remove impurities and stems manually.

[0046] The cleaning tank 12 is used to clean the green plum raw material. For example, the cleaning tank 12 may include a base frame and a water tank, and the water tank is arranged on the top of the base frame. The side wall of the water tank may be provided with a water inlet, and the water inlet may be connected to an external water supply pipe. A drain may be provided at the bottom of the water tank, and the drain may be connected to the factory drainage system. At the cleaning tank 12, workers can clean manually. Alternatively, an ultrasonic generator or vibrator is configured in the water tank, so that the green plum fruit can be cleaned by ultrasonic or vibration. Alternatively, a drain basket can also be configured in the water tank to lift the green plum fruit to a position above the water surface after cleaning, so as to facilitate the control of the plum fruit.

[0047] In the washing tank 12, workers can wash the selected green plums. The washed green plums can be transported to the extraction unit 30 through the feeding device 13 after the water is drained.

[0048] The feeding device 13 is used to lift the cleaned green plums to the top of the extraction tank 31 so as to feed the green plums through the feeding port 311 at the top of the extraction tank 31. For example, the feeding device 13 may be a lifting feeding machine, which may lift the trolley containing the cleaned green plums from the ground to the height of the top of the extraction tank 31. Alternatively, the feeding device 13 may also be other types of vertical conveying structures.

[0049] See also Figure 1 As shown, in an embodiment of the present invention, the wine inlet unit 20 is used to input the extraction base wine into the extraction tank 31. For example, the wine inlet unit 20 may include a wine inlet pump 21. The inlet of the wine inlet pump 21 is used to communicate with an external wine supply device, for example, the external wine supply device may be a wine tank truck.

[0050] The outlet of the wine inlet pump 21 can be communicated with the liquid inlet of the extraction tank 31 through a pipeline. It can be understood that a number of necessary control valves can be set on the pipeline to enable the wine inlet unit 20 to input the extraction base wine into the extraction tank 31 as needed and in quantity.

[0051] See also Figure 1 and Figure 2As shown, the extraction unit 30 includes an extraction tank 31, which is used to extract the washed green plums. The top of the extraction tank 31 may be provided with a feed port 311 for feeding. The bottom of the extraction tank 31 may be provided with a liquid inlet for feeding wine and a liquid outlet for discharging wine.

[0052] Preferably, the liquid inlet and the liquid outlet of the leaching tank 31 may share a common opening, for example Figure 2 The inlet and outlet 312 of the extraction tank shown in the figure. The opening can be used as the inlet for inputting the extraction base wine into the extraction tank 31, and can also be used as the outlet for the extraction tank 31 to discharge the wine. Alternatively, in other embodiments, the inlet and outlet of the extraction tank 31 can also be two openings opened independently.

[0053] A discharge port for discharging green plums may also be provided on the lower side wall of the extraction tank 31. After the extraction process is completed, the wine liquid may be discharged through the liquid outlet 312, and then the worker may take out the remaining green plums in the extraction tank 31 through the discharge port.

[0054] See also Figure 2 In one embodiment, the extraction unit 30 further includes a screen 33, which is connected to the inner peripheral wall of the extraction tank 31 and is located above the liquid outlet 312 of the extraction tank 31. The screen 33 may be a grid structure, and its circumferential outer edge is fixedly connected to the inner peripheral wall of the extraction tank 31. The screen 33 is used to separate the wine and the plum fruit.

[0055] Preferably, the discharge port can be arranged on the side wall of the extraction tank 31 above the screen 33. After the extraction process is completed, the wine is discharged through the liquid outlet 312 below the screen 33, and the plum fruit can be taken out through the discharge port above the screen 33.

[0056] It should be noted that in the present application, the extraction tank 31 is mainly used as a container for extraction treatment. The extraction treatment mainly refers to the process of soaking green plum fruit in a mixture of extraction base wine and sugar for a period of time to finally obtain green plum wine. It can be understood that the plum wine production system of the present invention is heavy, and multiple extraction tanks 31 can be configured according to actual production needs. Multiple extraction tanks 31 can be extracted simultaneously or independently.

[0057] In the embodiment of the present application, high-quality washed green plum fruit can be transported into the extraction tank 31 through the feeding unit 10. Extraction base wine can be input into the extraction tank 31 through the wine feeding unit 20. Moreover, syrup can be input into the extraction tank 31 through the sugar dissolving unit 40.

[0058] See also Figure 3 As shown, the sugar dissolving unit 40 includes a sugar dissolving tank 41 for forming syrup. A discharge port 411 may be provided at the bottom of the sugar dissolving tank 41, and the discharge port 411 may be communicated with the leaching tank 31.

[0059] A circulation port 412 may also be provided on the side wall of the sugar dissolving tank 41 , and the circulation port 412 is connected to the discharge port 411 through a pipeline.

[0060] In one embodiment, the sugar dissolving unit 40 further includes a sugar dissolving pump 42 and a homogenizing pump 43, which are connected to the sugar dissolving tank 41 through a circulation pipeline. Specifically, the sugar dissolving pump 42 and the homogenizing pump 43 can be arranged between the discharge port 411 and the circulation port 412 of the sugar dissolving tank 41.

[0061] The sugar dissolving pump 42 is used to circulate and drive the contents of the sugar dissolving tank 41 to flow through the homogenizing pump 43. The contents of the sugar dissolving tank 41 refer to sugar and water for dissolving sugar. For example, the water for dissolving sugar may be reverse osmosis RO (Reverse Osmosis) water.

[0062] like Figure 3 As shown, the homogenizing pump 43 is used to disperse and homogenize the content of the sugar dissolving pump 42. In this embodiment, by providing the sugar dissolving pump 42 and the homogenizing pump 43, the content of the sugar dissolving tank 41 can be continuously circulated, dispersed and homogenized, the quality of the sugar dissolving can be ensured, and thus the quality of the wine can be improved.

[0063] It is understood that in other embodiments, the homogenizing pump 43 may be omitted. At the same time, a stirring structure may be configured in the sugar dissolving tank 41 to accelerate and fully dissolve the sugar.

[0064] like Figure 3 As shown, a water inlet may be provided at the top of the sugar dissolving tank 41, and the water inlet may be connected to an external water supply device. For example, the external water supply device may be a reverse osmosis RO (Reverse Osmosis) water treatment device.

[0065] Further, see Figure 3 The sugar dissolving unit 40 further includes a water inlet heating device 44, which has a water inlet and a water outlet, wherein the water inlet is used to connect to an external RO water supply device, and the water outlet is connected to the sugar dissolving tank 41. The water inlet heating device 44 is used to heat the RO water to a set temperature and then transport it to the sugar dissolving tank 41 to ensure the sugar dissolving efficiency.

[0066] For example, the inlet water heating device 44 may be a plate heat exchanger, which can utilize a relatively high temperature heating medium to exchange heat with the RO water to increase the temperature of the RO water. The heating medium may be steam.

[0067] It can be understood that in other embodiments, the water inlet heating device 44 can also be a water supply tank equipped with a heating pipe.

[0068] like Figure 3As shown, the water outlet of the water inlet heating device 44 can also be connected to the circulation pipeline. That is, the RO water can also enter the sugar dissolving tank 41 through the circulation pipeline.

[0069] like Figure 3 As shown, the sugar dissolving unit 40 further includes a lower hopper 45, which can be connected to the circulation pipeline. The lower hopper 45 is used for workers to add sugar into the circulation pipeline. Alternatively, in other embodiments, the lower hopper 45 can also be connected to the sugar dissolving tank 41.

[0070] like Figure 3 As shown, in the embodiment of the present application, at the sugar dissolving unit 40, the RO water is heated to 25°C-30°C by the water inlet heating device 44 and enters the sugar dissolving tank 41. During the water inlet process, the water inlet can be stopped after the set amount is measured by the flow meter. The sugar dissolving pump 42 and the homogenizing pump 43 are started, and at the same time, the bagged white sugar is manually added to the lower hopper 45 to realize feeding while circulating. For example, the ratio of sugar to water can be 1:1. After the sugar addition is completed, the circulation pipeline continues to circulate for 3-4 hours, and the sugar dissolving is completed.

[0071] like Figure 3 As shown, the sugar dissolving pump 42 is also connected to the leaching tank 31, and is used to pump the syrup into the leaching tank 31 after the sugar dissolving is completed. Specifically, the outlet of the sugar dissolving pump 42 is connected to the liquid inlet at the bottom of the leaching tank 31 through the homogenizing pump 43.

[0072] In the embodiment of the present application, the green plum fruit, the base wine and the syrup can all be put into the extraction tank 31 for extraction as needed. Figure 2 In one embodiment, the extraction unit 30 further includes a first stirring device 32, which is disposed at the bottom of the extraction tank 31 and is used to stir the contents of the extraction tank 31. The contents of the extraction tank 31 refer to the green plum fruit, extraction base wine and syrup for extraction. By providing the first stirring device 32, the green plum fruit, extraction base wine and syrup in the extraction tank 31 can be stirred and fully mixed, which can help improve the effect of the extraction process and enhance the quality of the wine.

[0073] Preferably, the first stirring device 32 is a pneumatic stirring device. For example, the first stirring device 32 may include an air pump and an aeration pipe, the aeration pipe is arranged at the bottom of the extraction tank 31, and the air pump is connected to the aeration pipe. Air is introduced into the extraction tank 31 through the air pump and the aeration pipe, and the airflow can impact, break up, and mix the substances in the tank, so that the structure of the first stirring device 32 is simple and will not affect the quality of the wine.

[0074] The plum wine production system of the embodiment of the present application performs extraction in the extraction tank 31. Specifically, the green plum fruit, syrup, and extraction base wine can be mixed in a ratio of 1:1:1. Alternatively, it can be adjusted according to the specific process. After the green plum fruit, syrup, and extraction base wine are extracted in the extraction tank 31 for a set process time, for example, 3-6 months, the wine in the extraction tank 31 can be output to the next process.

[0075] See also Figure 1 As shown, in the embodiment of the present application, the refrigeration unit 50 is used to receive the wine output from the extraction tank 31 and cool and settle the wine. Figure 4 As shown, the freezing unit 50 includes a cooler 51 and a cold sink tank 52 , the liquid outlet of the leaching tank 31 is connected to the inlet of the cooler 51 , and the outlet of the cooler 51 is connected to the cold sink tank 52 .

[0076] For example, the cooler 51 may be a plate cooler. The cooler 51 is provided with an inlet and an outlet for inputting and outputting the material to be cooled. The inlet is connected to the liquid outlet of the extraction tank 31, and the outlet is connected to the cold sink tank 52. The cooler 51 is also provided with a coolant inlet and a coolant outlet for inputting a coolant. Therefore, the wine can enter the cooler 51 and be cooled by the coolant, and the cooled wine enters the cold sink tank 52 through the outlet of the cooler 51 for sedimentation.

[0077] It should be noted that, in the present application, the cold sinking tank 52 is mainly a container for sedimentation of the wine at low temperature. In order to accelerate the sedimentation of the wine, bentonite or starch and other sedimentation-aiding materials can be added into the cold sinking tank 52.

[0078] In the cold settling tank 52, the wine can be kept at a low temperature and allowed to settle. After a certain process time, the precipitated substances in the wine can be removed, or the substances in the wine that may potentially cause precipitation can be removed to avoid precipitation. In the cold settling tank 52, the wine will eventually be separated into layers, with the bottom layer being the sediment layer and the top being the clear liquid. In the cold settling tank 52, the settling temperature can be -2°C and the settling time can be 48 hours. Alternatively, it can also be adjusted according to the specific process.

[0079] like Figure 4 As shown, the bottom of the cooling tank 52 may be provided with a liquid inlet 521 for entering the wine and a liquid outlet 522 for exiting the wine. The liquid inlet 521 of the cooling tank 52 is communicated with the outlet of the cooler 51.

[0080] The liquid outlet 522 of the cold sink tank 52 is used to output the wine after sedimentation. It can be understood that the liquid outlet 522 of the cold sink tank 52 is preferably set at a higher position at the bottom of the cold sink tank 52. For example, the liquid outlet 522 of the cold sink tank 52 should be at least higher than the sediment layer.

[0081] See also Figure 4In one embodiment, the freezing unit 50 further includes a second stirring device 54, which is disposed at the bottom of the cold sink tank 52 and is used to stir the contents of the cold sink tank 52. The contents of the cold sink tank 52 refer to the cooled wine and the sedimentation-aiding substance used to accelerate sedimentation.

[0082] For example, the second stirring device 54 can be a pneumatic stirring device. The pneumatic stirring device has a simple structure and does not affect the quality of the wine. By setting the second stirring device 54, the wine and the sedimentation-aiding substance can be stirred to be fully mixed, which can be beneficial to improve the sedimentation effect of the wine and improve the quality of the wine. It can be understood that after the contents of the cold sedimentation tank 52 are stirred to be fully mixed, there is no need to start the second stirring device 54, so that the wine can be low-temperature precipitated in the cold sedimentation tank 52.

[0083] See also Figure 4 In one embodiment, the freezing unit 50 further includes a cooling jacket 53, which is wrapped around the outer periphery of the cold sink tank 52, and a sandwich space is formed between the cooling jacket 53 and the cold sink tank 52. The sandwich space is used to set a cooling pipeline. By setting the cooling jacket 53 and configuring the cooling pipeline in the sandwich space, the low temperature state of the cold sink tank 52 can be ensured, which can be beneficial to improving the sedimentation effect of the wine and improving the quality of the wine.

[0084] See also Figure 1 As shown, in the embodiment of the present application, the centrifugal unit 60 includes a centrifuge 61, and the inlet of the centrifuge 61 is connected to the liquid outlet of the cold sink tank 52. The centrifuge 61 is used to receive the wine output from the cold sink tank 52 and centrifuge it. By centrifuging the wine, suspended matter and impurities in the wine can be further removed, the quality and stability of the wine can be improved, and the purity and taste of the wine can be ensured.

[0085] like Figure 1 As shown, the centrifuge 61 is provided with a liquid outlet, and the liquid outlet of the centrifuge 61 is connected to the extraction tank 31. In this embodiment, the wine liquid centrifuged by the centrifuge 61 can be transported to the extraction tank 31 for buffering. Therefore, the extraction tank 31 and the finished wine buffer tank after centrifugation can share a tank body, thereby reducing the number of configured finished wine buffer tanks, reducing equipment space and investment, and reducing enterprise costs.

[0086] It can be understood that in other embodiments, the liquid outlet of the centrifuge 61 can also be connected to other external wine storage tanks.

[0087] See also Figure 1As shown, in the embodiment of the present application, the wine outlet unit 70 includes a wine outlet pump 71 and a pump pipe 72, the inlet of the wine outlet pump 71 is connected to the liquid outlet of the leaching tank 31, the outlet of the wine outlet pump 71 is connected to the medium inlet of the pump pipe 72, and the medium outlet of the pump pipe 72 is used to connect to an external wine storage device.

[0088] For example, the external wine storage device may be a wine tanker or tank truck, which can transport the wine to the packaging workshop for canning, thereby facilitating the process from production to packaging to achieve high efficiency.

[0089] In this embodiment, the finished wine can be output to an external wine storage device as needed through the wine output pump 71 and the lifting pipe 72, so that the use of the wine output unit 70 is more convenient and safe.

[0090] See also Figure 1 As shown, in one embodiment of the present application, the plum wine production system further includes a cleaning unit 80. The cleaning unit 80 is used to clean each tank and pipeline. For example, the cleaning unit 80 includes a cleaning pipeline 81 and a circulation pump 82, and the cleaning pipeline 81 is used to connect to the leaching tank 31, the sugar dissolving tank 41 and the cold precipitation tank 52. The circulation pump 82 is used to drive the cleaning liquid in the cleaning pipeline 81 to flow. Among them, the cleaning unit 80 can adopt a positioning cleaning CIP (cleaning in place) system.

[0091] In this embodiment, by providing a cleaning unit 80, the cleanliness of the plum wine production system can be improved, the cleanliness and hygiene of each unit can be ensured, and the quality of the wine can be ensured. When each process is completed, the cleaning unit 80 can clean the relevant units. For example, after the extraction unit 30 completes the extraction process, the cleaning unit 80 can clean the extraction tank 31 and its pipelines. For another example, after the sugar dissolving unit 40 completes the syrup supply, the cleaning unit 80 can clean the sugar dissolving tank 41 and its pipelines. For another example, after the freezing unit 50 completes the cooling and sedimentation of the wine, the cleaning unit 80 can clean the cooler 51, the cold sedimentation tank 52 and their pipelines.

[0092] It is worth noting that in the plum wine production system of the embodiment of the present application, some necessary control valves and detection instruments can be set on each tank body, at the inlet and outlet of each tank body, and on the pipelines between each unit to ensure the reliable and safe operation of the entire plum wine production system. These valves and detection instruments exist by default, and this application does not make specific restrictions on this.

[0093] The wine making process of the plum wine production system of the embodiment of the present application is roughly as follows:

[0094] Fresh green plums are manually screened, impurities removed, and stems removed at the screening platform 11, and then enter the cleaning tank 12 for cleaning and standby use. The cleaned green plums are lifted to the top of the leaching tank 31 by the feeding device 13, and are fed into the leaching tank 31 through the feeding port 311.

[0095] The tank truck loaded with the extraction base wine pumps the extraction base wine into the extraction tank 31 through the wine inlet pump 21.

[0096] RO water is heated to a set temperature by the water inlet heating device 44 and then enters the sugar dissolving tank 41. After reaching the water addition amount, the sugar dissolving pump 42 and the homogenizing pump 43 are started.
