Abstract
Description
Technical Field
[0001] This utility model relates to the field of enzyme fermentation technology, specifically a fruit wine fermentation tank. Background Technology
[0002] Early fruit wine fermentation technology relied on open containers or static fermentation, which had a long fermentation cycle (20-30 days). With the growth of industrial demand, closed fermentation tanks have gradually become popular, shortening the cycle to 7-15 days through mechanical stirring, temperature control systems and gas supply.
[0003] Existing fermentation tanks have stirring blind spots, resulting in uneven contact between fruit pulp and additives, poor fermentation stability, and difficulties in cleaning up fruit pit residue. To address these issues, we propose a new fruit wine fermentation tank that improves upon existing equipment. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a fruit wine fermentation tank.
[0005] The technical solution of this utility model is:
[0006] A fruit wine fermentation tank includes support legs, a tank body fixedly mounted above the support legs, a sealing cover fixedly mounted on the top of the tank body by screws, a feed pipe fixedly mounted on one side of the sealing cover, a slag discharge pipe fixedly mounted on one side of the tank body, a rotating drum rotatably mounted inside the tank body, and a stirring rod rotatably mounted inside the rotating drum.
[0007] As a preferred technical solution of this utility model: a first motor is fixedly installed at the bottom of the rotating drum, and through holes are opened on the side and bottom of the rotating drum.
[0008] As a preferred technical solution of this utility model: a ball bearing is fixedly provided on the outer periphery of the rotating drum, and a sliding groove is provided on the inner wall of the tank body. The ball bearing is embedded in the sliding groove and forms a sliding connection with the sliding groove.
[0009] As a preferred technical solution of this utility model: the bottom of the tank is provided with a plurality of filter holes, the positions of the filter holes corresponding to the positions of the through holes.
[0010] As a preferred technical solution of this utility model: a flow guide chamber is fixedly provided at the bottom of the tank, and a discharge pipe is fixedly provided at the end of the flow guide chamber away from the tank, and a filter screen is fixedly provided inside the discharge pipe.
[0011] As a preferred technical solution of this utility model: a second motor is fixedly installed on the sealing cover, the output shaft of the second motor is fixedly connected to the stirring rod, and a spiral blade is fixedly installed on the stirring rod.
[0012] As a preferred technical solution of this utility model: a scraper is provided around the spiral blade, and a connecting plate is fixedly provided at both the upper and lower ends of the scraper. The end of the connecting plate away from the scraper is fixedly connected to the stirring rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, by setting a second motor, drives the stirring rod to rotate. The spiral blades on the stirring rod can stir the mixture. Since a scraper is also set on the stirring rod, the stirring range is expanded while avoiding the material from adhering to the rotating drum, which facilitates the cleaning of the rotating drum and solves the problem of uneven contact between the pulp and additives in the existing models.
[0015] 2. This utility model solves the existing problem of cleaning fruit pit residue by setting up a rotating drum inside the tank and using a first motor to drive the rotation of the drum. Since the rotation direction of the drum is opposite to that of the stirring rod, the material is mixed more evenly. Under the action of centrifugal force, the fruit pit will separate from the pulp under the high-speed rotation of the drum and enter the gap between the tank and the rotating drum through the through hole. Finally, it is discharged through the slag discharge pipe. Attached Figure Description

[0024] 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.
[0025] Please see Figure 1-4 The present invention will describe the above technical solution in detail through the following embodiments:
[0026] A fruit wine fermentation tank includes support legs 1, a tank body 11 fixedly mounted above the support legs 1, a sealing cover 12 fixedly mounted on the top of the tank body 11 by screws, a feed pipe 13 fixedly mounted on one side of the sealing cover 12, a slag discharge pipe 14 fixedly mounted on one side of the tank body 11, a rotating drum 2 rotatably mounted inside the tank body 11, and a stirring rod 3 rotatably mounted inside the rotating drum 2. A second motor 31 is provided to drive the stirring rod 3 to rotate. The spiral blades 32 on the stirring rod 3 can stir the mixture. Since a scraper 33 is also provided on the stirring rod 3, the stirring range is expanded while avoiding material adhering to the rotating drum 2, which facilitates the cleaning of the rotating drum 2 and solves the problem of uneven contact between fruit pulp and additives in existing products.
[0027] Furthermore, a first motor 21 is fixedly installed at the bottom of the rotating drum 2. Through holes 22 are opened on the side and bottom of the rotating drum 2. By installing the first motor 21, the rotating drum 2 can be driven to rotate. When the rotating drum 2 rotates, under the action of centrifugal force, the fruit pit can enter the gap between the tank 11 and the rotating drum 2 through the through holes 22 on the drum wall, and finally be discharged through the slag discharge pipe 14.
[0028] It should be noted that the diameter of the through hole 22 on the cylinder wall is larger than the diameter of the bottom of the rotating cylinder 2. After the fruit pit is separated and the pulp is mixed evenly, it will enter the flow chamber 17 through the through hole 22 at the bottom of the cylinder.
[0029] It should be noted that a mounting plate is fixedly installed on the support leg, and the first motor 21 is fixedly installed on the mounting plate. The output shaft of the first motor 21 passes through the interior of the guide chamber 17 and is fixedly connected to the bottom of the rotating drum 2.
[0030] It should be noted that the first motor 21 and the second motor 31 rotate in opposite directions.
[0031] Furthermore, a ball bearing 23 is fixedly installed on the outer periphery of the rotating drum 2, and a groove 15 is provided on the inner wall of the tank body 11. The ball bearing 23 is fitted inside the groove 15 and forms a sliding connection with the groove 15. By setting the ball bearing 23, the rotating drum 2 can rotate more smoothly inside the tank body 11.
[0032] It is worth noting that the balls 23 are evenly distributed around the outer periphery of the rotating drum 2.
[0033] It is worth noting that there are two sets of ball bearings 23, and the ball bearings 23 are positioned above the through hole 22, so they will not affect the separation of the fruit pit.
[0034] Furthermore, the bottom of the can 11 is provided with several filter holes 16, the positions of which correspond to the positions of the through holes 22. By setting the filter holes 16 at the corresponding positions of the through holes 22, the pulp can enter the flow chamber 17 through the through holes 22 at the bottom of the can and the filter holes 16 of the can 11.
[0035] Specifically, the size of the filter hole 16 is the same as the size of the through hole 22.
[0036] Furthermore, a flow guide chamber 17 is fixedly provided at the bottom of the tank body 11, and a discharge pipe 18 is fixedly provided at the end of the flow guide chamber 17 away from the tank body 11. A filter screen 19 is fixedly provided inside the discharge pipe 18. By setting the flow guide chamber 17, the mixed fruit pulp can be discharged faster, and the filter screen 19 can further filter the fruit pulp.
[0037] It should be noted that the flow guide chamber 17 is conical in shape.
[0038] Furthermore, a second motor 31 is fixedly installed on the sealing cover 12. The output shaft of the second motor 31 is fixedly connected to the stirring rod 3. A spiral blade 32 is fixedly installed on the stirring rod 3. The second motor 31 drives the stirring rod 3 to rotate, and the spiral blade 32 on the stirring rod 3 can stir the mixture.
[0039] Furthermore, a scraper 33 is provided around the spiral blade 32, and a connecting plate 34 is fixedly provided at both the upper and lower ends of the scraper 33. The end of the connecting plate 34 away from the scraper 33 is fixedly connected to the stirring rod 3. Since the scraper 33 is also provided on the stirring rod 3, the stirring range is expanded while avoiding the material from adhering to the rotating drum 2, which facilitates the cleaning of the rotating drum 2.
[0040] It is worth noting that the surface of the scraper 33 is in contact with the inner wall of the rotating drum 2.
[0041] Working principle:
[0042] In use, the fruit wine fermentation tank of this utility model first feeds fruit pulp and additives into the feed pipe 13. Then, the second motor 31 is started, which drives the stirring rod 3 to rotate. The spiral blades 32 on the stirring rod 3 can stir the mixture, and the scraper 33 on the stirring rod 3 can scrape off the material adhering to the rotating drum 2 while stirring. Then, the first motor 21 is started, which drives the rotating drum 2 to rotate. Since the rotation direction of the rotating drum 2 is opposite to that of the stirring rod 3, the material is mixed more evenly, and under the action of centrifugal force... The fruit pits will separate from the pulp under the high-speed rotation of the rotating drum 2 and enter the gap between the tank 11 and the rotating drum 2 through the through hole 22. After the fruit pits are separated, the pulp will be mixed evenly and will enter the guide chamber 17 through the through hole 22 at the bottom of the drum and the filter hole 16 at the bottom of the tank 11. After being filtered again by the filter screen 19, it will be discharged through the discharge pipe 18. After the stirring is finished, the sealing cover 12 is opened, and the accumulated fruit pits are first manually discharged through the slag discharge pipe 14. Then the gap between the tank 11 and the rotating drum 2 is cleaned and rinsed. The filter screen 19 can be cleaned by backflushing with water from the discharge pipe 18.
[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
