Description

Technical Field

[0001] This invention relates to the field of food biological equipment technology, specifically to a juice-residue separation device for fruit wine production. Background Technology

[0002] Fruit wine is a fermented beverage made primarily from fruit juice through complete or partial alcoholic fermentation, containing a certain level of alcohol. Fruit wine typically possesses the flavor of fruit and generally has a low alcohol content, usually between 5% and 10%. Common fruit wines include grape wine, plum wine, and cider.

[0003] Fruit winemaking requires juicing fruit and separating the solids and liquids to obtain juice for brewing. However, ordinary juicers produce a mixture of juice and pulp, while the main raw material for winemaking is juice. To address this issue, the existing GZ-500 spiral crusher juicer includes a base with a feed chamber, a juicing chamber, and a slag discharge chamber fixedly connected to the top. A motor is fixedly connected inside the base and electrically connected to a controller. The motor output shaft has a transmission assembly, which includes a gear rack and two gears. The gear rack meshes with both gears. The motor output shaft is coaxially fixedly connected to one of the gears, and the other gear… A rotating rod is coaxially fixedly connected to the moving gear. The two ends of the rotating rod are rotatably connected to the side walls of the feeding chamber and the slag discharge chamber, respectively. A cutting blade, a spiral rod, and a blocking block are fixedly connected to the rotating rod located in the feeding chamber, the juicing chamber, and the slag discharge chamber, respectively. A filter cylinder is slidably fitted on the spiral rod. The bottom of the juicing chamber is connected to a juice outlet, and the bottom of the slag discharge chamber is connected to a slag discharge outlet. The controller controls the motor to operate, which in turn controls the cutting blade to initially crush the fruit. Then, the fruit pieces enter the juicing chamber, are squeezed by the spiral rod to extract juice, and are filtered by the filter cylinder. The juice is collected through the juice outlet, while the fruit pulp is carried to the slag discharge chamber by the rotation of the spiral rod and discharged through the slag discharge outlet.

[0004] In practice, although the sliding cooperation between the screw and the filter cylinder can press the fruit to separate the juice from the pulp, different fruits have different fiber contents. When processing fruits with high fiber content, the fibers in the fruit may easily entangle and become stuck in the filter holes during the pressing process, forming a physical barrier and causing the filter holes to become blocked, thus affecting the efficiency of juice-pulp separation.

[0005] Therefore, the present invention proposes a juice-residue separation device for fruit wine production to solve the above-mentioned problems. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a juice-residue separation device for fruit wine production. Based on the pressure exerted on the arc plate by the screw rod when pressing the fruit, the arc plate expands, thereby adjusting the misaligned apertures of the first and second filter holes. This prevents blockage caused by pressing high-fiber fruits, which would otherwise affect the efficiency of juice-residue separation.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: A juice-residue separation device for fruit wine production includes a support frame. A feeding cylinder, a separation chamber, and a slag discharge chamber are fixedly connected to the top of the support frame. The bottom of the feeding cylinder communicates with the separation chamber, and the side of the separation chamber away from the feeding cylinder communicates with the slag discharge chamber. A cutting component for cutting materials is provided inside the feeding cylinder, and a transmission component for driving the cutting component is provided on the outer wall of the feeding cylinder. A filter cylinder is provided inside the separation chamber, and a pressing component for pressing materials is provided inside the filter cylinder. The filter cylinder is composed of several arc plates surrounding it. An elastic strip is fixedly connected to one side of each arc plate, and the other side of each elastic strip is fixedly connected to an adjacent arc plate. All arc plates are located within the separation chamber, and both ends of the arc plates are separated by sliding grooves and sliders. The feed cylinder and slag discharge chamber sidewalls are not slidably fitted. Each side of the arc plate has a groove, and several springs are fixedly connected in each groove. Each other end of the arc plate is fixedly connected to an arc-shaped block corresponding to the groove. The other end of each arc block is fixedly connected to a spring in the groove on the adjacent arc plate. Each side of the arc plate without grooves has several first filter holes, while the side of the arc plate with grooves and the arc-shaped blocks have several second filter holes. The diameter of the second filter holes is larger than that of the first filter holes. When the fiber content of the processed fruit is higher, the pressing component squeezes the fruit, which increases the pressure on the arc plate and causes the arc plate to expand outward. The arc plate and the arc-shaped block in its groove move in opposite directions, which increases the diameter of the misaligned filter holes formed by the second filter holes on the arc plate and the arc block.

[0008] The technical principle of the above solution is as follows: the fruit is put into the feed cylinder, and the cutting component is driven by the transmission component to cut the fruit into uniform pieces. Then, the fruit pieces are pressed to extract juice by the pressing component. The higher the fiber content of the fruit, the greater the pressure generated by the screw extruding the fruit on the arc plate, the greater the expansion distance of the arc plate, and the larger the diameter of the misaligned filter holes generated by the expansion of the arc plate driving the first filter hole and the second filter hole to move.

[0009] The above solution has the following advantages: Compared with the existing technology, this solution uses the different fiber content of the fruit to make the pressure on the arc plate different. The arc plate adjusts the expansion distance according to the pressure, thereby adjusting the misaligned filter hole diameter of the arc plate and the second filter hole on the arc plate. This prevents the fruit fiber from tangling and getting stuck in the filter hole during the extrusion process, thus preventing blockage. At the same time, the adaptive adjustment of the arc plate reduces the risk of blockage, allowing the screw to rotate and extrude continuously, thereby improving the efficiency of juice and pulp separation.

[0010] Furthermore, the cutting assembly includes a rotating shaft, with both ends of the rotating shaft rotatably connected to the side wall of the feed cylinder, and several cross blades fixedly connected to the rotating shaft.

[0011] Beneficial effects: The cross-blade design cuts the fruit into small pieces, making it easier to squeeze the fruit evenly and improving the efficiency of juicing.

[0012] Furthermore, the transmission assembly includes a first motor and a transmission box. The first motor is fixedly connected to the bottom wall of the feed cylinder, and the transmission box is fixedly connected to the outer wall of the feed cylinder. The first motor is signal-connected to a controller. The output shaft of the first motor is coaxially fixedly connected to a first gear. The first gear meshes with a transmission gear chain. The transmission gear chain meshes with a second gear on the side away from the first gear. One end of the rotating shaft extends to the outside of the feed cylinder and is coaxially fixedly connected to the second gear.

[0013] Beneficial effects: The controller controls the operation of the first motor, which in turn drives the first gear to rotate. At the same time, the second gear rotates through the meshing relationship between the first gear, the transmission chain, and the second gear, thereby providing driving force to the rotating rod and the cross blade.

[0014] Furthermore, the pressing assembly includes a second motor, which is fixedly connected to the outer wall of the feed cylinder away from the separation chamber. The second motor is signal-connected to the controller. A screw rod is coaxially fixedly connected to the output shaft of the second motor. The other end of the screw rod extends into the slag discharge chamber and is rotatably connected to the side of the screw rod away from the feed cylinder. The portion of the screw rod located in the separation chamber is provided with screw blades.

[0015] Beneficial effects: The controller controls the operation of the first motor, which in turn drives the spiral rod to operate. The sliding cooperation between the spiral blade and the arc plate squeezes the pulp, separating the juice from the pulp.

[0016] Furthermore, several drainage brushes are fixedly connected to the outer wall of the arc plate near the groove.

[0017] Beneficial effects: The design of the flow brush guides the squeezed juice, allowing it to flow out quickly along the brush, thus reducing the chance of pulp mixing into the juice.

[0018] Furthermore, the drainage brush is coated with an adhesive coating.

[0019] Beneficial effects: The adhesive coating design absorbs some of the fruit pulp that flows out with the juice, reducing the pulp content in the juice and improving its purity.

[0020] Furthermore, a trapezoidal column is provided inside the separation chamber, and the trapezoidal column is fixedly connected to the screw rod. A slag discharge cylinder is connected to the side of the slag discharge chamber near the separation chamber. The slag discharge cylinder is connected to the separation chamber. A gap is provided between the trapezoidal column and the slag discharge cylinder. A slag discharge port is opened at the bottom of the slag discharge chamber.

[0021] Beneficial effects: The combination of the trapezoidal column and the spiral rod further compresses the fruit pomace, thereby reducing the water content in the pomace.

[0022] Furthermore, the bottom of the separation chamber is designed with an inclined structure, with the side of the bottom of the separation chamber near the feed cylinder being lower than the side near the slag discharge chamber, and a drain outlet is opened on the bottom wall of the separation chamber near the feed cylinder.

[0023] Beneficial effects: The inclined design ensures that all squeezed juice is collected through the drain, improving juice utilization.

[0024] Furthermore, the spring constant is 5-8 N / mm, and the spring pre-compression is 30%-40% of the free length.

[0025] Beneficial effects: By controlling the spring constant and pre-compression, the arc plate can be triggered to expand when squeezing high-fiber fruits, thus reducing the risk of blockage.

[0026] Furthermore, a current sensor is installed on the screw rod, and the current sensor is connected to the controller signal.

[0027] Beneficial effects: By monitoring the current of the screw shaft in real time through a current sensor, when the current continuously exceeds the set value, it is determined to be a blockage, and the second motor is controlled to reverse to solve the problem of sudden blockage.

[0028] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0039] The following detailed description illustrates the specific implementation method:

[0040] Example 1:

[0041] As attached Figure 1As shown: A juice-residue separation device for fruit wine production includes a support frame 1. A feed cylinder 2, a separation chamber 3, and a residue discharge chamber 4 are welded to the top of the support frame 1. The bottom of the feed cylinder 2 is connected to the separation chamber 3, and the side of the separation chamber 3 away from the feed cylinder 2 is connected to the residue discharge chamber 4. Since different fruits have different sizes, the larger the fruit, the longer the pressing time. To shorten the pressing time and improve pressing efficiency, as shown in the attached diagram... Figure 2 and attached Figure 4 As shown, the feed cylinder 2 is equipped with a cutting assembly for cutting materials. The cutting assembly includes a rotating shaft 6, with both ends of the rotating shaft 6 rotatably connected to the side wall of the feed cylinder 2. Several cross blades 7 are welded onto the rotating shaft 6. The rotating shaft 6 is also equipped with a transmission assembly that provides driving force for it, as shown in the attached diagram. Figure 4 and attached Figure 5 As shown, the transmission assembly includes a first motor 8 and a transmission box 9. The first motor 8 is preferably a Panasonic Minas A6 series AC servo motor. The first motor 8 is welded to the outer bottom wall of the feed cylinder 2, and the transmission box 9 is welded to the outer side wall of the feed cylinder 2. The first motor 8 is connected to a controller, which is preferably a Siemens S7-1200 PLC. The output shaft of the first motor 8 is coaxially welded with a first gear 10. The first gear 10 meshes with a transmission gear chain 12. The transmission gear chain 12 meshes with a second gear 11 on the side away from the first gear 10. One end of the rotating shaft 6 extends to the outside of the feed cylinder 2 and is coaxially welded with the second gear 11.

[0042] After cutting the fruit into even pieces, the juice is extracted by squeezing, as shown in the attached image. Figure 2As shown, the separation chamber 3 is equipped with a filter cylinder 5, and the filter cylinder 5 is equipped with a pressing assembly for pressing materials. The pressing assembly includes a second motor 13, which is preferably a SEW motor. The Eurodrive geared motor, the second motor 13, is welded to the outer wall of the feed cylinder 2 away from the separation chamber 3. The second motor 13 is connected to the controller signal. The output shaft of the second motor 13 is coaxially welded with a screw rod 14. The other end of the screw rod 14 extends into the slag discharge chamber 4 and is rotatably connected to the side away from the feed cylinder 2. The part of the screw rod 14 located in the separation chamber 3 is equipped with a screw blade. A current sensor is provided on the screw rod 14, preferably a Honeywell CSLA1CD. The current sensor is connected to the controller signal. The filter cylinder 5 is composed of several arc plates 501. One side of each arc plate 501 is glued and fixed with an elastic strip 507. The other side of each elastic strip 507 is glued and fixed to the adjacent arc plate 501. The arc plates 501 are all located in the separation chamber 3. Both ends of the arc plates 501 slide against the side walls of the feed cylinder 2 and the slag discharge chamber 4 respectively through grooves and sliders. One side of each arc plate 501 has a groove 502, and several elastic strips are welded into the groove 502. Spring 503, to ensure that the expansion of arc plate 501 is triggered when fruit with a fiber content higher than 3% is squeezed, has an elastic modulus of 5-8 N / mm and a pre-compression of 30%-40% of its free length. Arc blocks 504 corresponding to grooves are welded to the other end of each arc plate 501. The other end of each arc block 504 is welded to a spring 503 in a groove 502 on an adjacent arc plate 501. Several first filter holes 505 are provided on the side of the arc plate 501 without grooves 502. The arc plate 501 has a groove 502 on one side, and the arc block 504 has several second filter holes 506. The diameter of each second filter hole 506 is larger than the diameter of the first filter hole 505. In the initial state, all arc blocks 504 are located in the grooves 502 on adjacent arc plates 501. At this time, the second filter holes 506 on the arc plate 501 and the second filter holes 506 on the arc block 504 are misaligned, and the diameter of the misaligned filter holes is the same as the diameter of the first filter hole 505. When the fruit fiber content is less than 3%, as shown in the attached... Figure 3 As shown, the arc plate 501 is in its initial state; when the fruit fiber content is higher than 3%, as shown in the attached diagram... Figure 6 As shown, the spiral rod 14 squeezes the pulp, and the pulp under pressure exerts pressure on the arc plate 501, causing the arc plate 501 to expand. At this time, the arc block 504 moves away from the spring 503 fixed to it, reducing the overlap of the second filter holes 506 on the arc plate 501 and the arc block 504, thereby increasing the diameter of the misaligned filter holes formed by the misalignment of the second filter holes 506 on the arc plate 501 and the arc block 504. Several drainage brushes 15 are glued and fixed to the outer wall of the arc plate 501 near the groove 502. The drainage brushes 15 are provided with an adhesive coating, and the material of the adhesive coating is preferably food-grade silicone.

[0043] The specific implementation process is as follows: Fruit wine brewing requires juicing the fruit and separating the solid and liquid components, using the juice for brewing. Since the fruit varies in size, the fruit is put into the feed cylinder 2. The controller controls the first motor 8 to operate. The output shaft of the first motor 8 drives the first gear 10 to rotate synchronously. The first gear 10 drives the second gear 11 to rotate synchronously through the transmission rack, which in turn drives the rotating shaft 6, which is coaxially welded with the second gear 11, and the cross blade 7 on the rotating shaft 6 to rotate, cutting the fruit into uniform fruit pieces.

[0044] The controller controls the operation of the second motor 13. The output shaft of the second motor 13 drives the screw rod 14 to rotate synchronously, squeezing the fruit pieces. When squeezing fruits with low fiber content, such as apples (1.5% fiber content), the arc plate 501 does not expand. The fruit pieces are squeezed out of juice through the sliding cooperation of the arc plate 501 and the screw rod 14. The juice then enters the separation chamber 3 through the first filter hole 505 on the arc plate 501 and the misaligned filter hole formed by the misalignment of the second filter hole 506 on the arc plate 501 and the arc block 504. The fruit pulp enters the slag discharge chamber 4 with the rotation of the screw rod 14. When squeezing fruits with high fiber content, such as pineapples (3.5% fiber content), the pulp clumps together due to the high fiber content. At this time, when the screw rod 14 rotates and squeezes the pulp, the pulp blocks the first filter hole 505, and the pulp exerts pressure on the arc plate 501 that is higher than the elastic force of the spring 503. The arc plate 501 begins to expand, causing the arc block 504 and the groove 502 on the adjacent arc plate 501 to move in opposite directions. During the movement, the second filter hole 506 on the arc block 504 approaches the second filter hole 506 on the adjacent arc plate 501, thereby increasing the diameter of the misaligned filter hole formed by the misalignment of the second filter hole 506 on the arc plate 501 and the arc block 504 to avoid filter hole blockage. When the arc plate 501 expands, the guide brush 15 follows the movement, causing the guide brush 15 to approach the inner wall of the separation chamber 3. As the guide brush 15 gradually approaches the separation chamber 3 during the movement, the pressure on the inner wall of the separation chamber 3 increases. During the movement, the guide brush 15 can carry away the fruit residue attached to the inner wall of the separation chamber 3. At this time, the juice flows out through the misaligned filter hole and enters the separation chamber 3 through the guide brush 15. At the same time, the sticky coating on the guide brush 15 adsorbs the fruit residue through sticky physical adsorption to improve the purity of the juice.

[0045] Filtering juice through fixed filter holes can cause the fibers in high-fiber fruits to become entangled and clog the filter holes during the squeezing process, preventing the screw rod 14 from operating and reducing the efficiency of juice-particle separation. The expandable design of the arc plate 501 allows for adjustment of the misaligned filter hole diameter created by the arc plate 501 and the second filter hole 506 on the arc block 504. The higher the fruit fiber content, the greater the expansion of the arc plate 501 and the larger the misaligned filter hole diameter, thus preventing filter hole clogging and not interfering with the operation of the screw rod 14. At the same time, the design of the flow brush 15 and the adhesive coating effectively prevents fruit pulp from being discharged from the enlarged filter holes, thereby ensuring the purity of the juice.

[0046] The juice-residue separation device for fruit wine production described in Example 1 was compared with the traditional GZ-500 screw crusher and juicer. The specific experiments are as follows:

The current sensor + motor reverse function effectively solves sudden clogging (operation resumes after 2 reverse cycles). Separation efficiency: High-fiber fruit processing time is shortened by 32% (Pineapple: 18.4 min → 12.6 min). Juice yield is increased by 7-12% (Pineapple: 62.7% → 70.1%; Apple: 73.5% → 75.3%). Juice quality: The new device's guide brush + adhesive coating reduces fruit pulp contamination, and juice turbidity is reduced by 35-48% (Pineapple: 48.9 NTU → 25.3 NTU). The new equipment reduces downtime for cleaning and increases production efficiency by 40% (especially for high-fiber raw materials such as coconut).

[0078] Example 2:

[0079] As attached Figure 2 As shown, the difference from Embodiment 1 is that, in order to facilitate the separate collection of juice and pulp after juice and pulp separation, a trapezoidal column 16 is provided in the separation chamber 3. The trapezoidal column 16 is welded to the screw rod 14. The slag discharge chamber 4 is connected to the slag discharge cylinder 17 on the side near the separation chamber 3. The slag discharge cylinder 17 is connected to the separation chamber 3. A gap is provided between the trapezoidal column 16 and the slag discharge cylinder 17. A slag discharge port is opened at the bottom of the slag discharge chamber 4. The bottom of the separation chamber 3 is set as an inclined structure. The side of the bottom of the separation chamber 3 near the feed cylinder 2 is lower than the side near the slag discharge chamber 4. A drain outlet 18 is opened on the bottom wall of the separation chamber 3 on the side near the feed cylinder 2.

[0080] The specific implementation process is as follows: After the juice is squeezed out by the rotating screw 14, the pulp follows the screw 14 to rotate to the pulp discharge cylinder 17. The pulp is squeezed into a cake and discharged by the blocking effect of the trapezoidal column 16 on the pulp discharge cylinder 17. The inclined design of the bottom of the separation chamber 3 allows the juice to flow to the drain outlet 18 for discharge by gravity.

[0081] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
