Description

Technical Field

[0001] This utility model relates to the field of fruit wine fermentation and ripening technology, and specifically discloses a fruit wine fermentation and ripening device. Background Technology

[0002] Duoyi fruit is the fruit of *Tetracentron yunnanense*, a plant belonging to the genus *Tetracentron* in the family Rosaceae. Also known as Yiyi fruit, sour apple, sour papaya, and hawthorn, it is an economically valuable plant with both medicinal and edible uses. The plant is an evergreen tree with sparse branches; the twigs are stout and cylindrical, while older branches are purplish-brown. Duoyi fruit is rich in tannins and dietary fiber, with a sweet and sour taste that is appetizing, making it ideal as a raw material for the fermentation and ripening of fruit wines.

[0003] In existing fruit wine production technology, fruit wine fermentation is usually carried out in an independent fermentation tank. After fermentation is completed, the fermentation liquid and residue need to be separated into solid and liquid. The separated fruit wine is then discharged and transferred to a separately set ripening tank for ripening. This process involves multiple steps such as fruit wine discharge and transfer. Not only is the process cumbersome and time-consuming, but the open operation also makes it easy to introduce external bacteria, increasing the risk of fruit wine contamination and adversely affecting the quality of the final product.

[0004] To simplify operation, some technical solutions connect the fermentation tank and ripening tank into an integrated device via pipelines. After fermentation, the fruit wine can be directly discharged into the ripening tank through a valve. Such devices typically have a filter screen fixedly installed inside the fermentation tank to trap residue above the screen for solid-liquid separation. However, because the fermentation tank and ripening tank are an integrated structure, the ripening process continues after fermentation, making it impossible to quickly dump the residue inside the fermentation tank. This requires scooping out the residue. After scooping out the residue, the inner wall of the fermentation tank and the filter screen cannot be cleaned in time. The residual fruit residue can easily lead to spoilage and deterioration of the material, and may also pose hygiene risks to subsequent production.

[0005] Therefore, a fruit wine fermentation and ripening device is needed to solve the above problems. Utility Model Content

[0006] This invention proposes a fruit wine fermentation and ripening device. After fermentation, the fruit wine can be directly discharged into the ripening tank through a transfer pipe without additional transfer operations. While simplifying the production process, the sealed structure effectively prevents fruit wine contamination. The fermentation tank can be easily disassembled, facilitating quick emptying of internal residues. The inner wall of the fermentation tank and the filter screen can be cleaned separately, avoiding hygiene hazards to subsequent production.

[0007] This utility model is implemented as follows: a fruit wine fermentation and ripening device includes a fermentation box with openings on both the top and bottom sides, a ripening box below the fermentation box, a filter screen plate installed inside the fermentation box, a transfer pipe with a hand valve connected to the upper end of the ripening box, a support plate fixedly connected to the outer wall of the transfer pipe, a first sealing gasket abutting against the lower edge of the fermentation box installed at the upper end of the support plate, and multiple positioning plates that fit against the outer wall of the fermentation box fixedly connected to the upper end of the support plate.

[0008] The fermentation tank has an insertion groove on its upper edge. A second sealing gasket is installed inside the insertion groove. A top cover that is compatible with the top cover and abuts against the second sealing gasket is inserted into the insertion groove. A feeding pipe with a hand valve is fixedly connected to the upper end of the top cover.

[0009] A clamping mechanism is provided on the outer side of each of the positioning plates;

[0010] The outer wall of the ripening box is connected to a feeding port, and the outer wall of the feeding port is threadedly connected to a threaded cover. A sealing ring is installed at the top of the inner wall of the threaded cover, which abuts against the upper end of the feeding port.

[0011] As a preferred embodiment of the fruit wine fermentation and ripening device of this utility model, the pressing mechanism includes a support frame that is fixedly connected to the outer wall of multiple positioning plates. The upper end of the support frame is rotatably connected to two left-right distributed connecting columns. The upper ends of the two connecting columns are fixedly connected to a steering plate. The outer walls of the two steering plates are threaded with screws. The upper end of the top cover has two left-right distributed limiting grooves. The lower ends of the two screws are fixedly connected to pressing plates that extend into the two limiting grooves respectively. The upper ends of the two screws are fixedly connected to handwheels.

[0012] As a preferred embodiment of the fruit wine fermentation and ripening device of this utility model, the lower end of the top cover is rotatably connected to a stirring rack extending into the fermentation tank, and the upper end of the top cover is equipped with a drive motor whose output end is fixedly connected to the stirring rack.

[0013] As a preferred embodiment of the fruit wine fermentation and ripening device of this utility model, an installation cavity is provided between the inner wall and the outer wall of both the fermentation box and the ripening box, and a heating jacket is installed inside both installation cavities.

[0014] As a preferred embodiment of the fruit wine fermentation and ripening device of this utility model, a spring-loaded pressure relief valve is fixedly connected to the upper end of the top cover.

[0015] As a preferred embodiment of the fruit wine fermentation and ripening device of this utility model, the lower side of the outer wall of the ripening box is connected to a discharge pipe with a hand valve.

[0016] In a preferred embodiment of the fruit wine fermentation and ripening device of this utility model, the outer walls of the four positioning plates are jointly fixedly connected to a horizontal plate, and the left and right sides of the lower end face of the horizontal plate are fixedly connected to vertical plates. The left and right ends of the ripening box are fixedly connected to fixing rods that are respectively fixedly connected to two vertical plates, and the opposite sides of the two vertical plates are fixedly connected to mounting plates.

[0017] The beneficial effects of this utility model are:

[0018] 1. During installation, the fermentation box is positioned using the positioning plate and brought into contact with the first sealing gasket. Then, the top cover is inserted into the insertion slot and brought into contact with the second sealing gasket. The pressing mechanism presses down on the top cover to seal the device. After the fermentation is completed, the transfer pipe valve is opened to allow the fruit wine to flow into the ripening box through the filter screen. After the transfer pipe is closed, oak chips are added to the ripening box and its heating jacket is activated to control the temperature and allow it to stand. Thus, the fruit wine after fermentation can be directly discharged into the ripening box through the transfer pipe without additional transfer operations. This simplifies the production process and effectively prevents fruit wine contamination by relying on the sealing structure.

[0019] 2. During the ripening stage, release the pressing mechanism, lift the fermentation box vertically to detach it from the positioning plate, and remove the stirring rack through the limiting groove of the top cover. After directly pouring out the residue in the box, clean the inner wall of the fermentation box and the filter screen separately. At the same time, the top cover and stirring rack can be cleaned, which facilitates the quick pouring out of the residue inside the fermentation box and allows for separate cleaning of the inner wall of the fermentation box and the filter screen, avoiding hygiene hazards to subsequent production.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0028] Please see Figure 1-5 A fruit wine fermentation and ripening device includes a fermentation box 1 with openings on both the top and bottom sides, a ripening box 2 located below the fermentation box 1, a filter screen 3 installed inside the fermentation box 1, a transfer pipe 5 with a hand valve connected to the upper end of the ripening box 2, a support plate 4 fixedly connected to the outer wall of the transfer pipe 5, a first sealing gasket 6 installed at the upper end of the support plate 4 that abuts against the lower edge of the fermentation box 1, and multiple positioning plates 7 fixedly connected to the upper end of the support plate 4 that fit against the outer wall of the fermentation box 1.

[0029] The fermentation tank 1 has an insertion groove 8 on its upper edge. A second sealing gasket 10 is installed inside the insertion groove 8. A top cover 9 that is compatible with the insertion groove 8 and abuts against the second sealing gasket 10 is inserted into the insertion groove 8. A feeding pipe 25 with a hand valve is fixedly connected through the top end of the top cover 9.

[0030] A clamping mechanism is provided on the outer side of multiple positioning plates 7;

[0031] The outer wall of the ripening box 2 is connected to a feeding port 18. The outer wall of the feeding port 18 is threadedly connected to a threaded cover 19. A sealing ring is installed at the top of the inner wall of the threaded cover 19, which abuts against the upper end of the feeding port 18.

[0032] In this embodiment: When in use, the fermentation box 1 is vertically inserted into the inner side of multiple positioning plates 7, so that the lower edge of the fermentation box 1 contacts the first sealing gasket 6. At this time, the multiple positioning plates 7 adhere to the outer wall of the fermentation box 1 to prevent the fermentation box 1 from moving in the horizontal direction.

[0033] Then move the top cover 9 into the insertion groove 8 so that the top cover 9 comes into contact with the second sealing gasket 10, and prevent the top cover 9 from moving horizontally through the insertion groove 8.

[0034] The top cover 9 is then pressed downward by the clamping mechanism, and the fermentation tank 1 is subjected to downward pressure through the top cover 9 until the top cover 9 and the second sealing gasket 10 are tightly abutted together, and the lower edge of the fermentation tank 1 is tightly abutted together with the first sealing gasket 6, thereby preventing gas and liquid leakage, and the installation is completed.

[0035] At this time, the crushed pulp and auxiliary materials of Duoyiguo are added into the fermentation tank 1 through the feeding pipe 25. After the addition is completed, the feeding pipe 25 is sealed by the hand valve, and fermentation begins.

[0036] After fermentation, open the hand valve of transfer pipe 5. The fruit wine passes through the mesh of filter plate 3 and collects at the bottom of fermentation tank 1. Pulp residue, peel residue and other solids are retained above filter plate 3, achieving solid-liquid separation. Then close the hand valve of transfer pipe 5 and add ripening agents such as oak chips and spices through the feeding port 18 of ripening tank 2. The threaded cap 19 and sealing ring seal the feeding port 18 to ensure an anaerobic environment. Then close the heating jacket 21 of fermentation tank 1 and start the heating jacket 21 of ripening tank 2. Control the temperature within the required range and let it stand in the dark to carry out ripening. In this way, the fermented fruit wine can be directly discharged into ripening tank 2 through transfer pipe 5 without additional transfer operation. While simplifying the production process, the sealed structure effectively prevents fruit wine contamination.

[0037] During the ripening process, the top cover 9 is released by the clamping mechanism, and the fermentation box 1 is lifted vertically upwards, detaching it from the multiple positioning plates 7. Since the top cover 9 is inserted into the insertion slot 8, the top cover 9 along with the stirring rack 17 can be removed. This allows the residue inside the fermentation box 1 to be poured out directly. The fermentation box 1 is then moved to the cleaning area, where the inner wall and filter screen 3 of the fermentation box 1 can be cleaned directly. At the same time, the top cover 9 and the stirring rack 17 can also be cleaned. This method facilitates the quick pouring out of the residue inside the fermentation box 1 and allows for separate cleaning of the inner wall and filter screen 3, avoiding potential hygiene hazards in subsequent production.

[0038] As a technical optimization of this utility model, the clamping mechanism includes a support frame 11 that is fixedly connected to the outer wall of multiple positioning plates 7. The upper end of the support frame 11 is rotatably connected to two left and right distributed connecting columns 12. The upper ends of the two connecting columns 12 are fixedly connected to a steering plate 13. The outer walls of the two steering plates 13 are threaded through and connected to screws 15. The upper end of the top cover 9 is provided with two left and right distributed limiting grooves 14. The lower ends of the two screws 15 are fixedly connected to clamping plates 16 that extend into the two limiting grooves 14 respectively. The upper ends of the two screws 15 are fixedly connected to handwheels.

[0039] In this embodiment: when pressure is applied to the top cover 9, the steering plate 13, screw 15 and pressing plate 16 are rotated with the connecting column 12 until the connecting column 12 corresponds to the position of the limiting groove 14. Then the handwheel is turned, the screw 15 drives the pressing plate 16 to move down and enter the interior of the limiting groove 14, and the two pressing plates 16 simultaneously apply downward pressure to the top cover 9.

[0040] When the restriction on the top cover 9 is to be lifted, the handwheel is turned in the opposite direction. The screw 15 drives the clamping plate 16 to move upward and out of the interior of the limiting groove 14. Subsequently, the clamping plate 16 rotates with the connecting column 12 to a position away from the limiting groove 14, thus releasing the restriction on the top cover 9.

[0041] As a technical optimization of this utility model, the lower end of the top cover 9 is rotatably connected to a stirring rack 17 extending into the fermentation tank 1, and the upper end of the top cover 9 is equipped with a drive motor whose output end is fixedly connected to the stirring rack 17.

[0042] In this embodiment: the drive motor is installed on the top of the top cover 9, and the output shaft is fixedly connected to the stirring rack 17. In the early stage of fermentation, the drive motor drives the stirring rack 17 to rotate at low speed, so as to provide a mixing effect for the slurry and auxiliary materials.

[0043] As a technical optimization of this utility model, an installation cavity 20 is provided between the inner wall and the outer wall of both the fermentation box 1 and the ripening box 2, and a heating sleeve 21 is installed inside both installation cavities 20.

[0044] In this embodiment, an installation cavity 20 is provided between the double-layered walls of the fermentation box 1 and the ripening box 2, and a heating sleeve 21 is built in to heat the interior of the fermentation box 1 and the ripening box 2.

[0045] As a technical optimization of this utility model, a spring-loaded pressure relief valve 22 is fixedly connected through the upper end of the top cover 9.

[0046] In this embodiment: the carbon dioxide produced by fermentation increases the pressure inside the tank. When the pressure reaches the threshold, the spring-loaded pressure relief valve 22 automatically opens to release the gas.

[0047] As a technical optimization of this utility model, the lower side of the outer wall of the ripening box 2 is connected to a discharge pipe with a hand valve.

[0048] In this embodiment: after ripening is completed, the manual valve is opened, and the fruit wine is discharged through the discharge pipe under the action of gravity.

[0049] As a technical optimization of this utility model, the outer walls of the four positioning plates 7 are fixedly connected to a horizontal plate 23, and the left and right sides of the lower end face of the horizontal plate 23 are fixedly connected to vertical plates 24. The left and right ends of the ripening box 2 are fixedly connected to fixing rods that are respectively fixedly connected to two vertical plates 24, and the opposite sides of the two vertical plates 24 are fixedly connected to mounting plates.

[0050] In this embodiment, the device is securely connected by setting a horizontal plate 23, two vertical plates 24, two fixing rods, and two mounting plates.

[0051] The working principle and usage process of this utility model are as follows: When in use, the fermentation box 1 is vertically inserted into the inner side of multiple positioning plates 7 so that the lower edge of the fermentation box 1 contacts the first sealing gasket 6. At this time, the multiple positioning plates 7 adhere to the outer wall of the fermentation box 1 to prevent the fermentation box 1 from moving in the horizontal direction.

[0052] Then move the top cover 9 into the insertion groove 8 so that the top cover 9 comes into contact with the second sealing gasket 10, and prevent the top cover 9 from moving horizontally through the insertion groove 8.

[0053] The steering plate 13, screw 15, and clamping plate 16 then rotate with the connecting column 12 until the connecting column 12 corresponds to the position of the limiting groove 14. Then, the handwheel is turned, and the screw 15 drives the clamping plate 16 to move down and enter the interior of the limiting groove 14. The two clamping plates 16 simultaneously apply downward pressure to the top cover 9, and the top cover 9 applies downward pressure to the fermentation box 1 until the top cover 9 and the second sealing gasket 10 are tightly abutted, and the lower edge of the fermentation box 1 is tightly abutted with the first sealing gasket 6, thereby preventing gas and liquid leakage. The installation is then complete.

[0054] At this time, the crushed pulp and auxiliary materials of Duoyiguo are added into the fermentation tank 1 through the feeding pipe 25. After the addition is completed, the feeding pipe 25 is closed by the hand valve. Then the drive motor is started, which drives the stirring rack 17 to rotate at low speed, so that the pulp and auxiliary materials are evenly mixed. Then the heating jacket 21 of the fermentation tank 1 is heated to maintain the required temperature. The carbon dioxide produced by fermentation increases the pressure inside the fermentation tank 1. When the pressure reaches the threshold of the spring-type pressure relief valve 22, the spring-type pressure relief valve 22 automatically opens to release the air, maintaining a slightly positive pressure environment inside the fermentation tank 1.

[0055] After fermentation, open the hand valve of transfer pipe 5. The fruit wine passes through the mesh of filter plate 3 and collects at the bottom of fermentation tank 1. Pulp residue, peel residue and other solids are retained above filter plate 3, achieving solid-liquid separation. Then close the hand valve of transfer pipe 5 and add ripening agents such as oak chips and spices through the feeding port 18 of ripening tank 2. The threaded cap 19 and sealing ring seal the feeding port 18 to ensure an anaerobic environment. Then close the heating jacket 21 of fermentation tank 1 and start the heating jacket 21 of ripening tank 2. Control the temperature within the required range and let it stand in the dark to carry out ripening. In this way, the fermented fruit wine can be directly discharged into ripening tank 2 through transfer pipe 5 without additional transfer operation. While simplifying the production process, the sealed structure effectively prevents fruit wine contamination.

[0056] During the ripening process, the handwheel is turned in the opposite direction, and the screw 15 drives the pressing plate 16 to move upward and disengage from the inside of the limiting groove 14. Subsequently, the pressing plate 16 rotates with the connecting column 12 to a position away from the limiting groove 14, releasing the restriction on the top cover 9. The fermentation box 1 is then lifted vertically upward, disengaging it from the multiple positioning plates 7. Since the top cover 9 is inserted into the insertion groove 8, the top cover 9 along with the stirring rack 17 can be removed. The residue inside the fermentation box 1 can then be directly poured out. The fermentation box 1 can then be moved to the cleaning area, where the inner wall and filter screen 3 of the fermentation box 1 can be cleaned directly. At the same time, the top cover 9 and stirring rack 17 can also be cleaned. This method facilitates the quick and easy pouring out of the residue inside the fermentation box 1 and allows for separate cleaning of the inner wall and filter screen 3 of the fermentation box 1, avoiding potential hygiene hazards in subsequent production.
