Description

Technical Field

[0001] This utility model relates to the field of wine production technology, and in particular to a wine cold maceration brewing apparatus. Background Technology

[0002] Fully ripe grapes undergo a series of processes including sorting, washing, drying, destemming, pressing, adding sugar, bottling (with the addition of sulfites, pectinase, etc.), primary fermentation, secondary fermentation, clarification, distillation, and blending to produce high-quality wines with a ruby ​​red color, pleasant aromas, and a full-bodied flavor. Current winemaking equipment requires crushing the grapes before fermentation, and most equipment lacks a skin-pressing function. This often results in grape skins floating on the surface after crushing. However, maceration is the most crucial step in the winemaking process; poor maceration negatively impacts the final wine's quality.

[0003] In existing technologies, grape skins and juice are mixed together, and it is difficult to remove and separate the grape skins after the juice is drained. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a wine cold maceration brewing device.

[0005] The technical solution of this utility model is a wine cold maceration brewing device, comprising:

[0006] The tank body has an opening at the top and a circular hole at the bottom. A support is provided at the bottom of the tank.

[0007] The filter tube is a circular tube structure, rotatably mounted on the bottom of the tank body, and has several filter holes. A first annular sealing plate is provided on the inner side of the filter tube, and an upper feed pipe is coaxially mounted on the first annular sealing plate. A bottom sealing plate is provided at the bottom end of the filter tube. A cylinder for driving the bottom sealing plate to rise and fall is mounted on the bracket. A spline shaft is rotatably mounted on the bottom sealing plate, and a servo motor for driving the spline shaft to rotate is mounted on the bottom sealing plate. A spline sleeve is slidably mounted on the spline shaft along its length. A first connecting rod is connected between the spline sleeve and the inner wall of the filter tube. Multiple blades are installed on the outer wall of the filter tube. A rotating shaft is rotatably mounted on the upper end of the spline shaft, and a second connecting rod is connected between the rotating shaft and the upper feed pipe.

[0008] Preferably, an annular float is provided between the tank body and the upper feed pipe, and a second annular sealing plate is provided at the upper end of the annular float. A circular float is provided inside the upper feed pipe, and a circular sealing plate is provided on the circular float. Both the annular float and the circular float are provided with exhaust pipes, and a one-way valve is installed on the exhaust pipes. A drive assembly for driving the annular float and the circular float to rise and fall synchronously is provided at the upper end of the bottom sealing plate.

[0009] Preferably, the drive assembly includes a mounting shaft, a rotating handle, multiple winding reels, and multiple lifting ropes. A mounting frame is provided at the upper end of the tank body. The mounting shaft is rotatably mounted on the mounting frame. Multiple winding reels are all mounted on the mounting shaft. One end of each of the multiple lifting ropes is fixedly wound around the multiple winding reels. Each of the multiple lifting ropes is connected to a corresponding second annular sealing plate or circular sealing plate below it. The rotating handle is connected to the end of the mounting shaft. A limiting component for limiting the position of the mounting shaft is installed on the bottom sealing plate.

[0010] Preferably, the limiting assembly includes a gear and a locking block, with the gear mounted on the end of the mounting shaft and the locking block vertically slidably mounted on the bottom sealing plate.

[0011] Preferably, the bottom end of the circular float is flush with the bottom end of the annular float.

[0012] Preferably, a partition net is provided on the inner side of the upper feed pipe, and the partition net is located below the circular float and connected to the circular float.

[0013] Preferably, the upper end of the bottom sealing plate has a conical structure.

[0014] Compared with the prior art, this utility model has the following beneficial technical effects: The filter tube in this technical solution can isolate the grape skin and juice, facilitating subsequent solid-liquid separation; the cylinder drives the bottom sealing plate and the first annular sealing plate to move downwards synchronously, scraping off the grape skins adhering to the inner wall of the filter tube. When the bottom sealing plate separates from the bottom of the tank, the grape skins are automatically discharged from the inside of the filter tube under gravity, making it easy to remove the grape skins from the inside of the tank; the rotation of the driving blades can agitate the juice, which helps to promote the dissolution of substances, ensure uniform temperature distribution, and prevent the substances from settling and separating. The blades are set on the outside of the filter tube and will not come into contact with the grape skins during rotation, thus preventing the substances in the grape skins from being broken, improving the taste of the product.

[0018] Example 1

[0019] like Figures 1-3 As shown in the figure, the wine cold maceration brewing apparatus proposed in this embodiment includes a tank 1 and a filter tube 3.

[0020] The upper end of the tank body 1 is open, the bottom end of the tank body 1 has a circular hole, and the lower end of the tank body 1 is equipped with a support 2; furthermore, in order to facilitate material discharge, a drain pipe 27 is installed at the bottom end of the tank body 1, and a valve 28 is installed on the drain pipe 27.

[0021] The filter tube 3 is a circular tube structure. The filter tube 3 is rotatably installed at the bottom of the inner side of the tank body 1. The filter tube 3 has several filter holes. A first annular sealing plate 14 is provided on the inner side of the filter tube 3. An upper feed pipe 4 is coaxially provided on the first annular sealing plate 14. A bottom sealing plate 5 is provided at the bottom end of the filter tube 3. The upper end of the bottom sealing plate 5 has a conical structure. This design helps the grape skins at the upper end of the bottom sealing plate 5 to slide smoothly. A cylinder 29 for driving the bottom sealing plate 5 to rise and fall is installed on the bracket 2. A spline shaft 8 is rotatably installed on the bottom sealing plate 5. A servo motor 6 for driving the spline shaft 8 to rotate is also installed on the bottom sealing plate 5. A spline sleeve 10 is slidably installed on the spline shaft 8 along its length direction. A first connecting rod 9 is connected between the spline sleeve 10 and the inner wall of the filter tube 3. Multiple blades 7 are installed on the outer wall of the filter tube 3. A rotating shaft 12 is rotatably installed at the upper end of the spline shaft 8. A second connecting rod 13 is connected between the rotating shaft 12 and the upper feed pipe 4.

[0022] In this technical solution, a PLC controller is used to control the equipment.

[0023] In this embodiment, the material (grape skins and juice) is fed into the inside of the filter tube 3 through the upper feed pipe 4. Most of the juice flows into the cavity between the filter tube 3 and the tank 1 through the filter holes on the filter tube 3, while the grape skins remain inside the filter tube 3, thus achieving the effect of solid-liquid separation.

[0024] The servo motor 6 is started to drive the spline shaft 8 to rotate. The rotation of the spline shaft 8 drives the spline sleeve 10 to rotate, which in turn drives the filter tube 3 to rotate, which in turn drives multiple blades 7 to rotate. This enables the juice to be stirred and mixed, preventing substances in the juice from settling at the bottom. During the rotation of the blades 7, they do not come into contact with the grape skins, so they do not break the substances in the grape skins, thus improving the taste of the product.

[0025] After the cold soaking process is completed, valve 28 is opened to allow the juice inside tank 1 to be discharged through drain pipe 27. Once the juice is drained, cylinder 29 is activated to drive bottom sealing plate 5 to move downward. The movement of bottom sealing plate 5 causes spline shaft 8, first annular sealing plate 14, and upper feed pipe 4 to move downward. During the downward movement, first annular sealing plate 14 can scrape off the grape skins adhering to filter tube 3. When first annular sealing plate 14 moves to the bottom limit position, the grape skins inside filter tube 3 slide down, making it convenient for operators to remove the grape skins from inside tank 1. Furthermore, an annular groove can be provided at the bottom of tank 1 so that the grape skins fall into the annular groove.

[0026] It is worth noting that when performing cold impregnation, tank 1 needs to be placed in a constant temperature room to maintain the internal temperature of tank 1 within a suitable range.

[0027] In summary, the filter tube 3 in this technical solution can isolate the grape skins from the juice, facilitating subsequent solid-liquid separation. The cylinder 29 drives the bottom sealing plate 5 and the first annular sealing plate 14 to move downwards synchronously, scraping off the grape skins adhering to the inner wall of the filter tube 3. Once the bottom sealing plate 5 separates from the bottom of the tank 1, the grape skins are automatically discharged from the filter tube 3 under gravity, making it easy to remove the grape skins from the tank 1. The rotating blades 7 agitate the juice, promoting dissolution, ensuring uniform temperature distribution, and preventing sedimentation and stratification. Since the blades 7 are located on the outside of the filter tube 3, they do not come into contact with the grape skins during rotation, thus preventing damage to the grape skins. Crushing the grape skins enhances the product's flavor. (Grape skins contain a large amount of tannins. Moderate tannins can add structure and complexity to wine, making it more mellow. However, if the grape skins are excessively crushed, a large amount of tannins will be released into the grape juice quickly. Too much tannin will make the wine taste rough and bitter, reducing the drinking experience. This effect is more pronounced, especially for wines that aim for a fresh and smooth taste. Furthermore, crushed grape skins and other solid materials may release some unpleasant flavor compounds that were originally encased in the cells, such as certain aldehydes and terpenes. These substances may impart a raw, grassy, ​​or other disharmonious flavor to the wine, disrupting the overall flavor balance.)

[0028] Example 2

[0029] like Figure 1 and Figure 3 As shown, this embodiment of the wine cold maceration brewing apparatus, compared to Embodiment 1, includes an annular float 17 between the tank body 1 and the upper feed pipe 4. A second annular sealing plate 15 is provided at the upper end of the annular float 17. A circular float 18 is provided inside the upper feed pipe 4, with a circular sealing plate 16 on the circular float 18. The bottom end of the circular float 18 is flush with the bottom end of the annular float 17. Both the annular float 17 and the circular float 18 are provided with exhaust pipes 25, and a one-way valve 26 is installed on the exhaust pipes 25. A drive assembly for synchronously raising and lowering the annular float 17 and the circular float 18 is provided at the upper end of the bottom sealing plate 5. The drive assembly includes a mounting shaft 19, a rotating handle 23, multiple winding reels 20, and multiple lifting ropes 21. A mounting frame is provided at the upper end of the tank body 1. 30. The mounting shaft 19 is rotatably mounted on the mounting frame 30. Multiple winding reels 20 are mounted on the mounting shaft 19. One end of multiple lifting ropes 21 is fixedly wound around the multiple winding reels 20. The multiple lifting ropes 21 are respectively connected to the corresponding second annular sealing plate 15 or circular sealing plate 16 below them. The rotating handle 23 is connected to the end of the mounting shaft 19. A limiting component for limiting the mounting shaft 19 is installed on the bottom sealing plate 5. The limiting component includes a gear 22 and a locking block 24. The gear 22 is installed at the end of the mounting shaft 19, and the locking block 24 is vertically slidably mounted on the bottom sealing plate 5. Furthermore, a ring is provided directly below each of the multiple winding reels 20, and the multiple lifting ropes 21 pass through the multiple rings respectively. The rings are fixedly connected to the mounting frame 30 to limit the lifting ropes 21.

[0030] In this embodiment, rotating the handle 23 drives the mounting shaft 19 to rotate, achieving synchronous winding of multiple lifting ropes 21. This causes the annular float 17 and the circular float 18 to rise synchronously. When the circular float 18 moves from the upper feed pipe 4 to a position above the upper feed pipe 4, the locking block 24 is pushed downwards so that its end engages in the groove of the gear 22, thus limiting the angle of the mounting shaft 19. At this time, material can be fed into the upper feed pipe 4. After the feeding is completed, the locking block 24 is pushed upwards to release the limiting function of the mounting shaft 19, driving the annular float 17 and the circular float 18 to move slowly downwards. When the annular float 17 and the circular float 18 come into contact with the liquid surface, they float on the liquid surface and no longer move downwards. The one-way valve 26 only allows the gas inside the tank 1 to be discharged through the exhaust pipe 25. Through the above structure, the automatic venting function is achieved to reduce the oxygen content inside the tank 1.

[0031] It should be added that sealing rings are installed on the inner and outer sides of the bottom sealing plate 5, the circular float 18, and the annular float 17.

[0033] like Figure 3 As shown in the figure, the wine cold maceration brewing device proposed in this embodiment has an additional feature compared to Embodiment 2. In this embodiment, a partition net 31 is provided on the inner side of the upper feed pipe 4. The partition net 31 is located below and connected to the circular float 18. The partition net 31 can press the grape skins floating on the liquid surface down into the juice, thereby achieving full maceration of the skins.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
