Description

Technical Field

[0001] This utility model relates to the field of jujube juice technology, and in particular to a jujube juice production system. Background Technology

[0002] The fruit of the jujube is usually oval-shaped, turning red or yellow when ripe. It has a sweet taste and is rich in nutrients, containing abundant vitamins and minerals. It is often used to make dried fruit, candied fruit, or juice. Jujube contains a variety of vitamins, minerals, and bioactive components, giving it high health and economic value. In recent years, with the increasing health awareness of people, the demand for natural fruit juice products has been growing. Jujube juice, due to its unique flavor and nutritional components, has gradually gained favor among consumers, thus requiring a jujube juice production system.

[0003] In the traditional production process, the pulp of jujube fruit goes through multiple stages such as crushing, juicing, filtering, and sterilization. Material transfer is required between each stage. During the transfer process, contact between equipment and pipelines may introduce contaminants such as bacteria and impurities, increasing the risk of juice contamination. This contamination not only affects the taste and nutritional content of the juice but may also pose a threat to consumers' health. In addition, the material transfer between each stage takes a certain amount of time, reducing work efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a system for producing jujube juice.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A system for producing jujube juice includes a housing. A cylinder is fixed to the top of the housing, with an open bottom. The housing and cylinder are connected. A hopper is fixed to the inner wall of the cylinder. A crushing mechanism for crushing jujubes is installed inside the cylinder. A conveying mechanism for conveying jujubes is installed inside the hopper. A sleeve is inserted through the outer wall of the housing, with one end of the sleeve open. The discharge end of the hopper passes through the inner wall of the sleeve. Multiple circular holes are evenly spaced on the outer wall of the sleeve. A pressing mechanism for squeezing jujubes is installed inside the sleeve. A U-shaped plate is inclinedly installed on the inner wall of the housing, located below the sleeve. A filter screen is fixed to the inner wall of the U-shaped plate. The outer wall of the housing has... The system has a discharge port, with the lower edge of the discharge port flush with the lowest point of the filter screen. A vibration mechanism for vibrating the filter screen is installed on the inner side wall of the box. An electric heating coil is fixed to the bottom of the box, and a liquid storage tank is fixed to the bottom of the box. A connecting pipe runs through the bottom of the box, with one end of the connecting pipe extending to the top of the liquid storage tank. A solenoid valve is installed on the outer wall of the connecting pipe. A cooling mechanism for cooling the jujube juice is installed at the bottom of the liquid storage tank. This jujube juice production system integrates multiple processes such as crushing, juicing, filtering, and sterilization into one device, reducing the need for material transfer between different devices, lowering the risk of contamination, improving the taste and quality of the juice, saving considerable time, and increasing production efficiency.

[0007] Preferably, the crushing mechanism includes a rotating shaft, which is rotatably connected to the middle of the top of the cylinder, with one end of the rotating shaft located inside the discharge end of the hopper. Multiple crushing blades are fixed at equal intervals on the outer wall of the rotating shaft, and the length of the multiple crushing blades gradually decreases from top to bottom. A first motor is fixed to the top of the cylinder, and the output shaft of the first motor is fixed to the rotating shaft, driving the first motor to rotate the rotating shaft, thereby driving the multiple crushing blades to rotate, and crushing the jujubes.

[0008] Preferably, the conveying mechanism includes a spiral conveying blade, which is disposed inside the discharge end of the hopper and sleeved on the side wall of the rotating shaft. As the rotating shaft rotates, it drives the spiral conveying blade to rotate, thus conveying the crushed jujubes into the inner sleeve.

[0009] Preferably, the extrusion mechanism includes a screw, which is rotatably connected to the inner wall of the other end of the sleeve, and the diameter of the screw gradually increases from left to right. A second motor is fixed to the outer wall of the other end of the sleeve, and the output shaft of the second motor is fixed to the screw, driving the second motor to rotate the screw and convey the crushed jujubes from left to right. As the diameter of the screw gradually increases, the crushed jujubes are squeezed during the conveying process, which can squeeze out the juice contained in the jujubes, that is, perform juicing treatment.

[0010] Preferably, the vibration mechanism includes four support plates, which are respectively fixed at the four corners of the inner side wall of the housing, and all four support plates are located below the U-shaped plate. Slide rods are fixed at the four corners of the bottom of the U-shaped plate, and the four slide rods pass through the bottom of the four support plates. Springs are sleeved on the side walls of the four slide rods, with one end of each spring fixed to the U-shaped plate and the other end fixed to the four support plates. A connecting shaft is rotatably connected to the inner side wall of the housing, and a cam is sleeved on the side wall of the connecting shaft, with the cam located below the U-shaped plate. A third motor is fixed to the outer side wall of the housing. The output shaft and connecting shaft of the motor are fixed, driving the third motor to rotate the cam in conjunction with the connecting shaft. When the cam contacts the bottom of the spiral plate, the spiral plate moves upward along the inner side wall of the housing, that is, the four springs gradually stretch. As the cam continues to rotate, when the cam gradually separates from the bottom of the spiral plate, under the reaction of the four compressed springs, the spiral plate gradually moves downward. Because the cam rotates at a relatively fast speed, the cam and the spiral plate continuously make intermittent contact, while the four springs are in a state of continuous stretching and recovery. This keeps the filter screen in a state of vibration, preventing the filter screen from becoming clogged and affecting the filtration efficiency.

[0011] Preferably, the cooling mechanism includes a semiconductor cooling chip. The bottom of the liquid storage tank has an installation hole, and the semiconductor cooling chip is fixed to the inner wall of the installation hole. Multiple first fins are fixed at equal intervals on the cold end of the semiconductor cooling chip, and multiple second fins are fixed at equal intervals on the hot end of the semiconductor cooling chip. When the semiconductor cooling chip is energized, its cold end temperature drops rapidly, which in turn causes the surface temperature of the multiple first fins to drop rapidly. When the jujube juice comes into contact with the first fins, it can be quickly cooled. After cooling, it can be transferred to other production equipment for final juice processing.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This jujube juice production system integrates multiple processes such as crushing, juicing, filtering, and sterilization into one device, reducing the need for material transfer between different devices, lowering the risk of contamination, improving the taste and quality of the juice, and saving the time required for transfer between each process, thus improving work efficiency.

[0014] 2. By using a squeezing mechanism in conjunction with a sleeve and a vibration mechanism in conjunction with a filter screen, the jujube pulp after juicing is automatically collected and processed, eliminating the need for manual handling and improving the practicality of the system.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1 - Figure 5A system for producing jujube juice includes a housing 1, a cylinder 2 fixed to the top of the housing 1, the bottom of the cylinder 2 being open, and the housing 1 and the cylinder 2 being connected. A hopper 8 is fixed to the inner wall of the cylinder 2, and a crushing mechanism for crushing jujubes is installed inside the cylinder 2. A conveying mechanism for conveying jujubes is installed inside the hopper 8. A sleeve 9 is inserted through the outer wall of the housing 1, with one end of the sleeve 9 being open. The discharge end of the hopper 8 is inserted through the inner wall of the sleeve 9. Multiple circular holes 10 are evenly spaced on the outer wall of the sleeve 9. A squeezing mechanism for squeezing jujubes is installed inside the sleeve 9. A U-shaped plate 13 is inclinedly arranged on the inner wall of the housing 1, and the U-shaped plate 13 is located below the sleeve 9. A filter screen 14 is fixed to the inner wall of the U-shaped plate 13. An outlet is opened on the outer wall of the housing 1. The discharge port 4 is flush with the lowest point of the filter screen 14. The inner wall of the box 1 is equipped with a vibration mechanism for vibrating the filter screen 14. An electric heating coil 15 is fixed at the bottom of the box 1. A liquid storage tank 3 is fixed at the bottom of the box 1. A connecting pipe 23 passes through the bottom of the box 1, and one end of the connecting pipe 23 passes through the top of the liquid storage tank 3. A solenoid valve 24 is installed on the outer wall of the connecting pipe 23. A cooling mechanism for cooling the jujube juice is installed at the bottom of the liquid storage tank 3. This jujube juice production system integrates multiple processes such as crushing, juicing, filtering and sterilization into one device, reducing the need for material transfer between different devices, reducing the risk of contamination, improving the taste and quality of the juice, saving a lot of time and improving production efficiency.

[0023] Furthermore, the crushing mechanism includes a rotating shaft 11, which is rotatably connected to the middle of the top of the cylinder 2. One end of the rotating shaft 11 is located inside the discharge end of the hopper 8. Multiple crushing blades 12 are fixed at equal intervals on the outer wall of the rotating shaft 11, and the length of the multiple crushing blades 12 gradually decreases from top to bottom. A first motor 5 is fixed at the top of the cylinder 2, and the output shaft of the first motor 5 is fixed to the rotating shaft 11. The first motor 5 drives the rotating shaft 11 to rotate, thereby driving the multiple crushing blades 12 to rotate, and crushing the jujubes.

[0024] Furthermore, the conveying mechanism includes a spiral conveying blade 16, which is disposed inside the discharge end of the hopper 8 and sleeved on the side wall of the rotating shaft 11. As the rotating shaft 11 rotates, it drives the spiral conveying blade 16 to rotate, thus conveying the crushed jujubes into the inner sleeve 9.

[0025] Furthermore, the extrusion mechanism includes a screw 17, which is rotatably connected to the inner wall of the other end of the sleeve 9. The diameter of the screw 17 gradually increases from left to right. A second motor 6 is fixed to the outer wall of the other end of the sleeve 9, and the output shaft of the second motor 6 is fixed to the screw 17. The second motor 6 drives the screw 17 to rotate, conveying the crushed jujubes from left to right. As the diameter of the screw 17 gradually increases, the crushed jujubes are squeezed during the conveying process, which can squeeze out the juice contained in the jujubes, i.e., perform juicing.

[0026] Furthermore, the vibration mechanism includes four support plates 18, which are fixed to the four corners of the inner wall of the housing 1, and all four support plates 18 are located below the U-shaped plate 13. Slide rods 19 are fixed to the four corners of the bottom of the U-shaped plate 13, and the four slide rods 19 pass through the bottom of the four support plates 18. Springs 20 are sleeved on the side walls of the four slide rods 19, with one end of each spring 20 fixed to the U-shaped plate 13 and the other end fixed to each of the four support plates 18. A connecting shaft 21 is rotatably connected to the inner wall of the housing 1, and a cam 22 is sleeved on the side wall of the connecting shaft 21, with the cam 22 located below the U-shaped plate 13. A third motor 7 is fixed to the outer wall of the housing 1, and the output shaft of the third motor 7 is connected to... The connecting shaft 21 is fixed, and the third motor 7 drives the cam 22 to rotate in conjunction with the connecting shaft 21. When the cam 22 contacts the bottom of the retaining plate 13, the retaining plate 13 moves upward along the inner wall of the housing 1, that is, the four springs 20 gradually become stretched. As the cam 22 continues to rotate, when the cam 22 gradually disengages from the bottom of the retaining plate 13, under the reaction action of the four compressed springs 20, the retaining plate 13 gradually moves downward. Because the rotation speed of the cam 22 is relatively fast, the cam 22 and the retaining plate 13 continuously make intermittent contact, while the four springs 20 are in a state of continuous stretching and recovery. This allows the filter screen 14 to be in a state of vibration, avoiding clogging of the filter screen 14 and affecting the filtration efficiency.

[0027] Furthermore, the cooling mechanism includes a semiconductor cooling chip 25. The bottom of the liquid storage tank 3 has an installation hole, and the semiconductor cooling chip 25 is fixed to the inner wall of the installation hole. Multiple first fins 26 are fixed at equal distances on the cold end of the semiconductor cooling chip 25, and multiple second fins 27 are fixed at equal distances on the hot end of the semiconductor cooling chip 25. When the semiconductor cooling chip 25 is energized, its cold end temperature drops rapidly, which in turn causes the surface temperature of the multiple first fins 26 to drop rapidly. When the jujube juice comes into contact with the first fins 26, it can be quickly cooled. After cooling, it can be transferred to other production equipment for final juice processing.

[0028] Working Principle: During operation, the cleaned and pitted jujubes are placed inside the equipment, and the power switch is turned on. This drives the first motor 5 to rotate the shaft 11, which in turn rotates multiple crushing blades 12 to crush the jujubes. The rotation of the shaft 11 also drives the spiral conveyor blades 16 to rotate, conveying the crushed jujubes into the sleeve 9. At this time, the power switch for the second motor 6 is turned on, driving the screw 17 to rotate and conveying the crushed jujubes from left to right. As the diameter of the screw 17 gradually increases, the crushed jujubes are compressed during conveying, squeezing out the juice contained within them, which then falls through multiple round holes 10 into the filter screen below. The juice is discharged from the top of the filter screen 14 through one end of the sleeve 9. The juice falling into the top of the filter screen 14 is filtered by the filter screen 14 and then falls into the bottom of the box 1. Some pulp and pulp will remain on the surface of the filter screen 14. In order to avoid the filter screen 14 from becoming clogged and affecting the filtration efficiency, the power switch of the third motor 7 is turned on. The third motor 7 drives the cam 22 to rotate in conjunction with the connecting shaft 21. When the cam 22 contacts the bottom of the retaining plate 13, the retaining plate 13 moves upward along the inner side wall of the box 1, that is, the four springs 20 are gradually stretched. As the cam 22 continues to rotate, when the cam 22 gradually disengages from the bottom of the retaining plate 13, the four springs 20 are compressed. Under the reaction force, the U-shaped plate 13 gradually moves downward. Due to the high rotation speed of the cam 22, the cam 22 and the U-shaped plate 13 continuously come into intermittent contact, while the four springs 20 are in a state of continuous stretching and recovery. This causes the filter screen 14 to vibrate, allowing the fruit pulp residue to roll off the filter screen 14 and be collected at the discharge port 4. At the same time as filtering, the power switch of the electric heating coil 15 is turned on. When the electric heating coil 15 is energized, its surface temperature rises rapidly to the set value, heating the jujube juice to achieve sterilization. After a period of time, the power switch of the solenoid valve 24 is turned on, making the solenoid valve 24 connected. At this time, the jujube juice flows through the connecting pipe 2 3. The liquid flows into the storage tank 3. At this time, the power switch of the semiconductor cooling chip 25 is turned on. When the semiconductor cooling chip 25 is powered on, its cold end temperature drops rapidly, which in turn causes the surface temperature of the multiple first fins 26 to drop rapidly. When the jujube juice comes into contact with the first fins 26, it can be cooled down quickly. After cooling, it can be transferred to other production equipment for final juice processing. The whole process integrates multiple links such as crushing, juicing, filtering and sterilization, avoiding the need for material transfer between each operation link. This prevents the introduction of bacteria, impurities and other contaminants due to contact between equipment and pipelines during the transfer process, reduces the risk of juice contamination and improves product quality.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
