Description

Technical Field

[0001] This invention relates to the technical field of starch processing, and in particular to a syrup concentration device for starch sugar processing. Background Technology

[0002] Starch sugar, as an important food additive and industrial raw material, is widely used in beverages, confectionery, baked goods, pharmaceuticals, and chemicals. It is mainly produced by converting starch raw materials into syrup through a series of processes such as pretreatment, liquefaction, and saccharification, followed by further concentration. The concentration of syrup involves removing water from the syrup to increase the sugar concentration. In traditional syrup concentration processing, the syrup needs to be heated in a heater to evaporate the water and obtain hard sugar. After that, it is taken out and the syrup is poured back into the heater for repeated concentration. However, this concentration method cannot achieve continuous concentration processing of syrup, and its operation is cumbersome and inefficient. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a syrup concentration device for starch sugar processing, the specific technical solution of which is as follows: A syrup concentration device for starch sugar processing includes a heating cylinder and a material spreading structure, a collection trough, and a scraper located inside the heating cylinder. The axis of the heating cylinder is horizontal. The interior of the heating cylinder is used to store syrup and heat the syrup. The material spreading structure is located inside the heating cylinder and is used to spread the syrup on the inner wall of the heating cylinder. The scraper is used to scrape off the heated and concentrated sugar flakes from the inner wall of the heating cylinder and let them fall into the collection trough. The collection trough is inclined and is used to discharge the sugar flakes. The heating cylinder rotates continuously and continuously concentrates the syrup.

[0004] Furthermore, the material spreading structure consists of a material spreading box, a feeding pipe, and a cover plate. The material spreading box is vertical, and its length direction is parallel to the axis of the heating cylinder. The material spreading box is connected to a feeding pipe for supplying syrup into the material spreading box. A material spreading long opening is opened on the side wall of the material spreading box. The material spreading long opening is horizontal, and the cover plate is installed on the material spreading long opening. The cover plate can slide in the vertical direction.

[0005] Furthermore, a first motor is fixed on the material leveling box, and a rotating column is provided at the output end of the first motor. The rotating column is parallel to the axis of the heating cylinder, and multiple first push-pull arms roll on the rotating column. Each first push-pull arm is rotatably provided with a second push-pull arm. The first push-pull arms and the second push-pull arms form a V-shape, and the second push-pull arms are rotatably mounted on the cover plate.

[0006] Furthermore, a rotating shaft is provided inside the material leveling box, which is parallel to the axis of the heating cylinder. Spiral blades are provided on the outer wall of the rotating shaft, and a second motor is provided on the material leveling box to provide power to the rotating shaft.

[0007] Furthermore, the heating cylinder consists of inner and outer walls, with a high-pressure cavity between the two walls; The heating cylinder is provided with multiple sets of holes, which are arranged in a ring along the axis of the heating cylinder. Each set of holes consists of multiple insertion holes arranged along the axis of the heating cylinder. Each set of holes is equipped with a connecting post, which is provided with multiple insertion posts. The ends of the insertion posts are slidably inserted into the insertion holes, and the ends of the multiple insertion posts and the inner wall of the heating cylinder form a complete arc surface.

[0008] Furthermore, it also includes an outer cylinder located outside the heating cylinder, the outer cylinder being coaxial with the heating cylinder, and annular grooves being provided on the inner walls of both ends of the outer cylinder. The annular grooves are composed of arc-shaped grooves and V-shaped grooves. The end of the connecting post is slidably inserted into the annular groove. When the connecting post slides in the arc-shaped groove, the post blocks the insertion hole. When the connecting post slides in the V-shaped groove, the post is withdrawn from the insertion hole.

[0009] Furthermore, a ring is rotatably mounted on the inner wall of the outer cylinder, and the ring is connected to the heating cylinder by multiple connecting plates. The outer cylinder is equipped with a third motor and a transmission wheel for providing power to the ring.

[0010] Furthermore, a circular groove coaxial with the ring is formed on the outer circumference of the ring, and the groove and the inner wall of the outer cylinder form a closed space. The connecting plate is hollow inside, and the closed space is connected to the high-pressure cavity in the heating cylinder through the connecting plate. An air inlet pipe connected to the closed space is provided on the outer wall of the outer cylinder.

[0011] The advantages of this invention are: The equipment design allows for continuous syrup feeding, heating, concentration, and discharge, enabling continuous syrup processing. This avoids the cumbersome steps of repeated feeding and unloading required in traditional methods, significantly improving production efficiency and processing capacity. This concentration method allows for automated syrup processing, reducing manual intervention and minimizing product quality fluctuations caused by human factors. Furthermore, its simple operation and structure simplify the processing flow and reduce production costs.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0015] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0016] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0017] like Figures 1 to 7 As shown, a syrup concentration device for starch sugar processing according to the present invention includes a heating cylinder 1 and a material spreading structure 2, a collection tank 3, and a scraper 4 located inside the heating cylinder 1. The axis of the heating cylinder 1 is horizontal. The interior of the heating cylinder 1 is used to store syrup and heat the syrup. The material spreading structure 2 is located inside the heating cylinder 1 and is used to spread the syrup on the inner wall of the heating cylinder 1. The scraper 4 is used to scrape off the heated and concentrated sugar flakes on the inner wall of the heating cylinder 1 and let them fall into the collection tank 3. The collection tank 3 is inclined and is used to export the sugar flakes. The heating cylinder 1 rotates continuously and continuously concentrates the syrup.

[0018] In detail, the spreading structure 2 is located inside the lower side of the heating cylinder 1 and is used to spread syrup to the bottom of the inner wall of the heating cylinder 1. The collecting trough 3 and the scraper 4 are both located on the side of the inner wall of the heating cylinder 1, and the scraper 4 is inclined and slides in contact with the inner wall of the heating cylinder 1. The positions of the spreading structure 2 and the collecting trough 3 are fixed, and the scraper 4 is fixed on the collecting trough 3. In use, the heating cylinder 1 rotates continuously around its axis, and the spreading structure 2 spreads the syrup evenly on the bottom of the inner wall of the heating cylinder 1. As the heating cylinder 1 rotates, the spreading structure 2 continues to spread the syrup. The heating cylinder 1 moves the syrup on its inner wall and heats the syrup, causing the water in the syrup to evaporate. The syrup is concentrated and solidified on the inner wall of the heating cylinder 1 to form sugar flakes. When the sugar flakes move with the heating cylinder 1 to its highest point and move downwards, the scraper 4 contacts the sugar flakes and scrapes them off. The sugar flakes fall into the collection tank 3. Because the collection tank 3 is tilted, the sugar flakes slide down naturally in the collection tank 3. After cleaning, the local heating cylinder 1 moves back to the position of the material spreading structure 2 to receive syrup, thereby realizing the continuous concentration processing of syrup.

[0019] It should be noted that when the syrup moves to the position of scraper 4, it has already hardened into a sugar flake state due to prolonged heating. To prevent the syrup from flowing out at the end of the heating cylinder 1, a baffle can be added to the end of the heating cylinder 1. Also, due to the rotation of the heating cylinder 1, when the syrup concentration is low, its fluidity is strong. At this time, as the heating cylinder 1 rotates, the excess syrup on the inner wall of the heating cylinder 1 can flow downward naturally, thereby automatically spreading the syrup on the inner wall of the heating cylinder 1. During the scraping process, since scraper 4 is in direct contact with the inner wall of the heating cylinder 1 and the position of scraper 4 is generally higher than the axis of the heating cylinder 1, even if debris is generated during the scraping process, it will fall into the collection tank 3. In actual production, the amount of debris generated is small and does not affect the normal use of the equipment.

[0020] The equipment design allows for continuous syrup feeding, heating, concentration, and discharge, enabling continuous syrup processing. This avoids the cumbersome steps of repeated feeding and unloading required in traditional methods, significantly improving production efficiency and processing capacity. This concentration method allows for automated syrup processing, reducing manual intervention and minimizing product quality fluctuations caused by human factors. Furthermore, its simple operation and structure simplify the processing flow and reduce production costs. Because sugar flakes can be promptly scraped off and discharged, syrup residue within the equipment is reduced, facilitating cleaning and maintenance, thereby lowering maintenance costs and downtime. In summary, this new type of continuous concentration equipment offers significant advantages in improving production efficiency, ensuring product quality, reducing energy consumption, and simplifying operation, representing a significant technological innovation in the starch sugar processing industry.

[0021] Furthermore, the material spreading structure 2 consists of a material leveling box 5, a feeding pipe 6, and a cover plate 8. The material leveling box 5 is vertical, and the length direction of the material leveling box 5 is parallel to the axis of the heating cylinder 1. The material leveling box 5 is connected to the feeding pipe 6 for supplying syrup into the material leveling box 5. A material leveling elongated opening 7 is opened on the side wall of the material leveling box 5. The material leveling elongated opening 7 is horizontal, and the cover plate 8 is installed on the material leveling elongated opening 7. The cover plate 8 can slide in the vertical direction.

[0022] In detail, the length of the uniform feeding port 7 is slightly less than the horizontal length of the heating cylinder 1, so that when the syrup is discharged through the uniform feeding port 7, the syrup can cover the inner wall of the heating cylinder 1. The feed pipe 6 is used to continuously supply syrup into the uniform feeding box 5, and the syrup flows naturally to the inner wall of the heating cylinder 1 through the uniform feeding port 7.

[0023] When it is necessary to concentrate syrups of different concentrations, or to change the thickness of the syrup spread on the inner wall of the heating cylinder 1, the coverage area of ​​the cover plate 8 on the uniform material outlet 7 can be adjusted by adjusting the position of the cover plate 8 on the uniform material outlet 5, thereby adjusting the outflow speed of the syrup through the uniform material outlet 7. The cover plate 8 is slidably installed on the uniform material outlet 5.

[0024] Furthermore, a first motor 9 is fixed on the material leveling box 5, and a rotating column 10 is provided at the output end of the first motor 9. The rotating column 10 is parallel to the axis of the heating cylinder 1. Multiple first push-pull arms 11 roll on the rotating column 10, and a second push-pull arm 12 is rotatably provided on each first push-pull arm 11. The first push-pull arm 11 and the second push-pull arm 12 form a V-shape, and the second push-pull arm 12 is rotatably mounted on the cover plate 8.

[0025] In detail, the first motor 9 drives the rotating column 10 to rotate, and the rotating column 10 pushes the cover plate 8 to slide on the equalization box 5 through the first push-pull arm 11 and the second push-pull arm 12, thereby providing power for the adjustment of the cover plate 8.

[0026] Furthermore, a rotating shaft 13 is provided inside the material leveling box 5. The rotating shaft 13 is parallel to the axis of the heating cylinder 1. Spiral blades 14 are provided on the outer wall of the rotating shaft 13. A second motor 15 is provided on the material leveling box 5 to provide power to the rotating shaft 13.

[0027] In detail, the second motor 15 can drive the rotating shaft 13 and the spiral blade 14 to rotate, thereby using the spiral blade 14 to push the syrup in the uniform material box 5 to flow away from the feed pipe 6, so that the syrup can be evenly distributed in the uniform material box 5, and avoid the syrup discharged into the uniform material box 5 by the feed pipe 6 from accumulating near the feed pipe 6 and causing the spreading structure 2 to be unable to spread the syrup evenly on the inner wall of the heating cylinder 1.

[0028] Furthermore, the heating cylinder 1 is composed of inner and outer walls, with a high-pressure cavity between the two walls; The heating cylinder 1 is provided with multiple sets of holes, which are arranged in a ring along the axis of the heating cylinder 1. Each set of holes consists of multiple insertion holes arranged along the axis of the heating cylinder 1. Each set of holes is equipped with a connecting post 16, and multiple insertion posts 17 are provided on the connecting post 16. The ends of the insertion posts 17 are slidably inserted into the insertion holes, and the ends of the multiple insertion posts 17 and the inner wall of the heating cylinder 1 form a complete arc surface.

[0029] In detail, the insert 17 seals the insertion hole and forms a complete arc surface inside the heating cylinder 1. This allows the syrup to be carried by the arc surface. After the syrup is concentrated into sugar flakes, the connecting column 16 is moved and the insert 17 is pulled out. At this time, the high-pressure cavity is connected to the inside of the heating cylinder 1 through the insertion hole on the inner wall of the heating cylinder 1. The high-pressure gas in the high-pressure cavity can be blown through the insertion hole to the space between the inner wall of the heating cylinder 1 and the sugar flakes, thereby using the airflow to demold the sugar flakes and make it easy for the sugar flakes to fall off. After the sugar flakes fall off, the insert 17 is reinserted into the insertion hole.

[0030] Since the heating cylinder 1 is composed of inner and outer walls, insertion holes need to be opened on both the inner and outer walls. The insertion post 17 passes through the two insertion holes. When demolding is required, the insertion post 17 can be pulled out of the insertion hole on the inner wall of the heating cylinder 1. At this time, the insertion post 17 needs to block the insertion hole on the outer wall of the heating cylinder 1.

[0031] Furthermore, it also includes an outer cylinder 18 located outside the heating cylinder 1. The outer cylinder 18 is coaxial with the heating cylinder 1. Annular grooves are formed on the inner walls of both ends of the outer cylinder 18. The annular grooves are composed of arc-shaped grooves 19 and V-shaped grooves 20. The end of the connecting post 16 is slidably inserted into the annular groove. When the connecting post 16 slides in the arc-shaped groove 19, the insert post 17 blocks the insertion hole. When the connecting post 16 slides in the V-shaped groove 20, the insert post 17 is withdrawn from the insertion hole.

[0032] In detail, as the heating cylinder 1 rotates, it drives multiple connecting posts 16 and multiple insert posts 17 to rotate. The connecting posts 16 slide in the guide groove, which guides and limits the positions of the connecting posts 16 and insert posts 17. When the connecting posts 16 move into the V-shaped groove 20, the insert posts 17 are in the unloading position. At this time, the scraper 4 scrapes off the sugar sheet, and the high-pressure air in the high-pressure cavity blows the sugar sheet through the insertion hole to demold it. When the connecting posts 16 move into the arc groove 19, the end of the insert post 17 forms a complete arc surface with the inner wall of the heating cylinder 1. Thus, the rotation of the heating cylinder 1 provides power for the movement of the insert posts 17.

[0033] Furthermore, a ring 21 is rotatably disposed on the inner wall of the outer cylinder 18. The ring 21 is connected to the heating cylinder 1 by multiple connecting plates 22. The outer cylinder 18 is provided with a third motor 23 and a transmission wheel 24 for providing power to the ring 21.

[0034] In detail, the ring 21 is rotatably mounted on the inner wall of the outer cylinder 18, one end of the connecting plate 22 is fixed on the ring 21, and the other end of the connecting plate 22 is fixed on the outer wall of the heating cylinder 1. The third motor 23 is fixed on the outer wall of the outer cylinder 18, and the transmission wheel 24 is connected to the ring 21 for transmission. The third motor 23 provides power to the transmission wheel 24, thereby achieving the purpose of supporting the heating cylinder 1 and supplying power.

[0035] Furthermore, a circular groove coaxial with the ring 21 is formed on the outer circumference of the ring 21. The circular groove and the inner wall of the outer cylinder 18 form a closed space. The connecting plate 22 is hollow inside. The closed space is connected to the high-pressure cavity in the heating cylinder 1 through the connecting plate 22. An air inlet pipe 25 connected to the closed space is provided on the outer wall of the outer cylinder 18.

[0036] In detail, external air can be pumped into the enclosed space through the air inlet pipe 25, and the high-pressure gas in the enclosed space can be discharged into the high-pressure cavity in the heating cylinder 1 through the hollow connecting plate 22, thereby realizing the pneumatic demolding operation.

[0037] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
