Description

Technical Field

[0001] This utility model relates to the field of food processing equipment, specifically to a syrup conveying device for fruit juice processing. Background Technology

[0002] Syrup conveying equipment for fruit juice processing refers to a system used to receive and convey syrup during the production of fruit juice, fruit juice beverages, or concentrated fruit juice.

[0003] Existing syrup conveying equipment mostly uses a screw conveyor mechanism in conjunction with a straight discharge pipe to achieve material transfer. However, in actual use, it has been found that relying solely on the screw thrust is insufficient to effectively overcome the adhesion resistance of syrup at the end of the discharge pipe. Furthermore, the existing discharge port structure lacks an effective fluid guiding design, making it impossible to achieve uniform discharge around the entire circumference. This results in an uneven flow state of syrup during the conveying process, with a high flow velocity at the center and a slow flow velocity at the edges. Consequently, high-viscosity syrup accumulates to varying degrees at different locations around the pipe wall. This uneven discharge characteristic not only accelerates the formation of local blockages but also requires frequent equipment shutdowns for cleaning, severely restricting the efficiency of continuous production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing a syrup conveying device for fruit juice processing, thereby solving the aforementioned technical problems.

The device is characterized by further comprising: A conical pressure boosting discharge head is located at the other end of the conveying pipe. The conical pressure boosting discharge head is used to increase the pressure when the syrup is discharged. A conical distributor is installed inside a conical pressurized discharge head, with the conical end of the distributor facing in the opposite direction to the conical end of the pressurized discharge head. An annular channel for syrup to pass through is formed between the conical distributor and the pressurized discharge head.

[0018] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0019] Example 1: like Figures 1 to 3 As shown, this utility model provides a syrup conveying device for fruit juice processing, including a horizontally arranged conveying pipe 1, a conveying spiral roller 2 rotatably installed inside the conveying pipe 1, and a feed inlet 3 at the top of one end of the conveying pipe 1, and further including: Conical pressure boosting discharge head 4 is located at the other end of the conveying pipe 1. The conical pressure boosting discharge head 4 is used to enhance the pressure when the syrup is discharged. A conical diverter 5 is disposed inside a conical pressurized discharge head 4, and the conical end of the conical diverter 5 faces the opposite direction to the conical end of the conical pressurized discharge head 4. An annular channel 8 for syrup to pass through is formed between the conical diverter 5 and the conical pressurized discharge head 4.

[0020] In use, the syrup is injected into the horizontal conveying pipe 1 through the inlet 3. After the equipment is started, the conveying spiral roller 2 begins to rotate, smoothly pushing the syrup towards the conical pressurized discharge head 4. When the syrup reaches the vicinity of the discharge head, the syrup flow comes into contact with the conical surface of the conical distributor 5, forcing the syrup to stop moving forward in a concentrated manner. Instead, it is evenly distributed into the annular channel 8, which gradually narrows between the distributor and the inner wall of the discharge head. During this process, the syrup is compressed and pressurized, and is evenly and stably squeezed out from the outlet of the annular channel 8, avoiding accumulation and blockage at the center of the outlet.

[0021] Example 2: like Figures 1 to 3 As shown, in conjunction with the technical solution of Embodiment 1, in this technical solution, the discharge end of the conical pressurized discharge head 4 is connected to a quick-connect discharge nozzle 6, and the inner wall of the quick-connect discharge nozzle 6 is mirror-polished. The quick-connect discharge nozzle 6 is quickly connected to the conical pressurized discharge head 4 by rotation. When the syrup flows through the discharge nozzle after being pressurized, the mirror-polished surface of its inner wall can minimize frictional resistance, allowing the syrup to pass smoothly without producing any adhesive residue, ensuring smooth discharge and facilitating subsequent disassembly and cleaning.

[0022] Furthermore, the conical distributor 5 is fixedly installed inside the conical pressurized discharge head by several supporting ribs 7. The conical surface of the conical distributor 5 and the inner wall of the conical pressurized discharge head 4 form a gradually narrowing annular channel 8. When the syrup flows in, it is guided by the distributor to the annular channel formed between its conical surface and the inner wall of the discharge head. This channel gradually narrows from the inlet to the outlet, so that the syrup is continuously compressed and pressurized during the process, eventually forming a uniform annular flow that is stably extruded.

[0023] Furthermore, the outer wall of the conveying pipe 1 is covered with an insulation layer, and radially distributed heat-conducting oil pipes 9 are provided on the outer wall of the conveying pipe 1 along the axial direction, with the heat-conducting oil pipes 9 located within the insulation layer. The heat-conducting oil is continuously circulated through the heat-conducting oil pipes 9 coiled around the outer wall of the conveying pipe 1, and the heat is evenly transferred to the internally flowing syrup through the pipe wall. At the same time, the outer insulation layer can effectively reduce heat loss, maintain a suitable temperature for the syrup, and prevent it from clogging due to cooling and solidification during the conveying process.

[0024] Furthermore, the conical distributor 5 has an internal cavity, which is connected to the heat transfer oil pipe 9 through a flow channel located inside the support rib 7. The heated heat transfer oil flows out from the heat transfer oil pipe 9 on the outer wall of the conveying pipe 1 and enters the internal cavity of the conical distributor 5 through the hidden flow channel inside the support rib 7. In this way, the distributor itself can also be heated, ensuring that all key surfaces in contact with the syrup have a uniform temperature, preventing the syrup from sticking or solidifying on the surface of the distributor when it cools down, and ensuring that the annular discharge channel remains unobstructed.

[0025] Furthermore, a spiral blade 10 is fixedly installed on the outer side of the conveying spiral roller 2, and an elastic scraper 11 is fixedly installed on the outer edge of the spiral blade 10. The elastic scraper 11 abuts against the inner wall of the conveying pipe 1. When the equipment is started, the conveying spiral roller 2 is driven to rotate, and the elastic scraper 11 fixed on the outer edge of the spiral blade 10 rotates accordingly. Its edge always moves in close contact with the inner wall of the conveying pipe 1, effectively removing the syrup adhering to the pipe wall through continuous scraping, realizing self-cleaning during the conveying process and preventing material accumulation that could lead to blockage.

[0026] Furthermore, a cleaning port 12 is provided on the bottom surface of the conveying pipe 1, and a cleaning cover 13 is hinged to the cleaning port 12. A sealing strip is provided on the contact surface between the cleaning cover 13 and the conveying pipe 1. When it is necessary to clean or inspect the inside of the conveying pipe 1, the hinged cleaning cover 13 is opened. After cleaning or inspection is completed, the cleaning cover 13 is closed, and the sealing strip on the contact surface is used to achieve a seal, ensuring that no leakage occurs from the cleaning port 12 when the equipment is conveying syrup normally.

[0027] Furthermore, the surface of the conical distributor 5 is coated with a polytetrafluoroethylene (PTFE) non-stick coating. Because of this coating, syrup does not easily adhere to the surface, allowing it to be smoothly guided along the conical surface to the annular channel 8, effectively preventing syrup buildup or adhesion that could cause blockages.

[0028] Furthermore, an observation window 14 is provided on the side wall of the conical pressurized discharge head 4, and the observation window 14 is made of heat-resistant material. The operator can directly observe the flow status of the syrup inside the discharge head through the observation window 14 on the side wall without stopping the machine and disassembling the equipment, thereby realizing real-time monitoring of the operating status and rapid fault diagnosis.

[0029] The working principle of a syrup conveying device for fruit juice processing disclosed in this application is as follows: When in use, the equipment is started, and the syrup enters the horizontal conveying pipe 1 from the inlet 3. It is pushed forward by the internal conveying spiral roller 2. The elastic scraper 11 on the outside scrapes off the syrup adhering to the inner wall of the conveying pipe 1 during the rotation. The syrup in the conveying pipe 1 is gradually moved to the conical pressurized discharge head 4. When it encounters the conical diverter 5 in the discharge head, the syrup is forced to flow into the gradually narrowing annular channel 8 between the two to achieve pressurization and uniform extrusion. At the same time, the conveying pipe 1 and the internal cavity of the diverter are circulated and heated through the heat-conducting oil pipe 9. Combined with the heat insulation layer, the syrup is prevented from solidifying. Meanwhile, the mirror-polished quick-connect discharge nozzle 6 and the non-stick coating effectively reduce residue. The side wall observation window 14 facilitates monitoring of the status, and the bottom cleaning port 12 can periodically remove accumulated impurities.

[0030] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
