Description

Technical Field

[0001] This utility model belongs to the field of flaxseed oil processing technology, and in particular relates to a flaxseed oil deodorization system. Background Technology

[0002] Flaxseed oil needs to be deacidified and deodorized after cold pressing. The principle is based on the fact that the boiling points of fatty acids and off-odor substances in the oil are lower than those of the oil itself. By introducing direct steam into the oil under high temperature and high vacuum conditions, these undesirable components are removed using the principle of steam distillation.

[0003] Chinese patent CN222821506 U discloses a cold-pressing deacidification and deodorization device for flaxseed oil. The patent describes a device that "includes a processing chamber, within which a thin oil pan is fixedly installed…the processing chamber is connected to a cooling pipe via a sealed bearing, a worm gear is welded to the surface of the cooling pipe, and the worm gear is meshed with a worm, the bottom end of which is connected to a drive motor." This design uses multiple thin oil pans to form an oil film and employs a rotatable cooling pipe to agitate and heat the oil, offering advantages such as structural integration.

[0004] However, in the above scheme, firstly, the deodorization section relies on a static thin oil pan, and the oil flows naturally by gravity. The thickness and uniformity of the oil film formed are limited, resulting in a longer path for the volatilization of substances such as fatty acids and limited mass transfer efficiency. There is still room for improvement in deodorization effect and efficiency.

[0005] Secondly, its cooling section adopts a rotating cooling pipe structure that runs through the processing box. This structure relies on complex dynamic seals (such as sealed bearings) to maintain a high vacuum environment inside the box. Under long-term operation, the dynamic seal components are prone to wear and leakage. Maintaining the vacuum level is costly and difficult. In addition, the manufacturing and maintenance of the rotating structure are complex, and there is a potential risk of leakage.

[0006] Furthermore, the device highly integrates deodorization and cooling functions into a single treatment box. When internal scaling or components such as cooling pipes need maintenance, the entire equipment must be disassembled on a large scale, making the maintenance process cumbersome, resulting in long downtime and affecting the continuity of production.

[0007] Therefore, it is necessary to design a high-efficiency, reliable and easy-to-maintain flaxseed oil deodorization system to address the shortcomings of existing flaxseed oil deodorization devices in terms of deodorization efficiency, operational reliability and ease of maintenance.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] Example 1 A preferred embodiment of the flaxseed oil deodorization system provided by this utility model is, for example... Figures 1 to 5 The system shown includes a flaxseed oil deodorization system, comprising a main frame 1; an atomizing deodorization tower 2 and a cooling tower 3 installed on the main frame 1, with the cooling tower 3 located below the atomizing deodorization tower 2, and the oil outlet of the atomizing deodorization tower 2 and the oil inlet of the cooling tower 3 connected by a large-diameter main connecting pipe 4; a centrifugal atomizing distributor 6 installed inside the atomizing deodorization tower 2 for atomizing the flaxseed oil; and a liquid collection hood 7 installed below the centrifugal atomizing distributor 6 for collecting unatomized oil. Oil droplets; a partition 5 disposed inside the cooling tower 3, which divides the interior of the cooling tower 3 into an upper cooling chamber and a lower liquid collection chamber; several layers of heat dissipation guide plates 501 fixedly installed on the upper surface of the partition 5, which form a flow channel in the cooling chamber for the oil to spiral downward; and a baffle plate 504 rotatably disposed in the flow channel; an atomizer 8 and a cooling water circulation tank 301 disposed on one side of the main frame 1, and a heating tank 602 disposed on the other side.

[0025] It should be noted that some existing flaxseed oil deodorization systems still have certain shortcomings in actual use. In the comparison document, the deodorization and cooling functions are highly integrated into a single tower, which leads to maintenance difficulties; the deodorization section uses a static thin oil pan with a thick oil film, resulting in limited mass transfer efficiency; and the cooling section uses a rotating cooling pipe with dynamic sealing, which poses a risk of leakage under long-term operation.

[0026] In this embodiment, by modularizing the system into an atomizing deodorization tower 2 and a cooling tower 3, and connecting them through a large-diameter main connecting pipe 4, the two core functional units can work collaboratively or be inspected and maintained independently, greatly improving the maintainability of the equipment. The centrifugal atomizing distributor 6 can disperse grease into micron-level oil mist, which greatly increases the contact area between oil and steam compared to traditional thin oil pans, thereby significantly improving deodorization efficiency and speed. At the same time, the cooling tower 3 adopts a cooling method that combines a static spiral flow channel composed of heat dissipation guide plates 501 with a rotating baffle plate 504. Without the need for complex dynamic sealing, the forced stirring of the baffle plate 504 breaks down the thermal boundary layer of the grease, achieving efficient and reliable heat exchange cooling.

[0027] In a further preferred embodiment of the present invention, a plurality of atomizing nozzles 801 are arranged in a ring below the liquid collection hood 7, and each atomizing nozzle 801 is connected to the atomizer 8 through an atomizing connecting pipe 802.

[0028] In this embodiment, the atomizer 8 generates clean steam, which is delivered to the annularly distributed atomizing nozzles 801 via the atomizing connecting pipe 802. These nozzles spray steam upwards or at an angle upwards, making full and efficient countercurrent contact with the oil mist falling from the centrifugal atomizing distributor 6. The steam stripping effect carries away free fatty acids and odor substances in the oil mist, thereby completing deep deodorization. The annular arrangement ensures the uniformity of steam distribution.

[0029] In a further preferred embodiment of the present invention, the cooling water circulation tank 301 forms a circulating cooling circuit with the cooling pipe 505 disposed below the partition plate 5 through the first circulation pipe 302 and the second circulation pipe 303.

[0030] In this embodiment, the cooling medium in the cooling water circulation tank 301 is pumped into the cooling pipe 505 through the first circulation pipe 302. After absorbing the heat carried by the grease coming down from the upper spiral channel, the heated water flows back to the cooling water circulation tank 301 through the second circulation pipe 303 to dissipate heat, forming a closed-loop cooling system that is energy-saving and efficient.

[0031] In a further preferred embodiment of this utility model, the two ends of the main connecting pipe 4 are connected to the oil outlet of the atomizing deodorizing tower 2 and the oil inlet of the cooling tower 3 respectively through flanges.

[0032] In this embodiment, a flange connection is used, making the main connecting pipe 4 a component that can be quickly disassembled. When it is necessary to clean the spiral flow channel inside the cooling tower 3 or to inspect the bottom of the atomizing deodorizing tower 2, the two towers can be separated simply by removing the flange bolts. This realizes modular maintenance of the equipment and solves the pain point of the extremely inconvenient internal maintenance of traditional integrated equipment.

[0033] In a further preferred embodiment of the present invention, the heat dissipation guide plate 501 is a multi-layered concentric annular structure, and a guide hole 502 is provided at its bottom.

[0034] In this embodiment, the multi-layered concentric annular heat dissipation guide plates 501 form a spiral cooling path from top to bottom. The high-temperature grease flows downwards in the flow channel, prolonging the heat exchange time; the guide holes 502 at the bottom ensure that the grease can flow smoothly from the upper layer to the lower layer, and finally collect in the central area of ​​the partition 5 to enter the next stage, with a smooth and unobstructed flow process.

[0035] In a further preferred embodiment of the present invention, the spoiler 504 is driven by a motor 503, which is installed at the top center of the partition 5 and located inside a sealed housing.

[0036] In this embodiment, the motor 503 serves as a power source, driving the baffle 504 to rotate continuously within the static flow channel formed by the heat dissipation guide plate 501. The rotating baffle 504 exerts a strong shearing and stirring effect on the flowing grease, effectively disrupting the thermal boundary layer adhering to the surface of the heat dissipation guide plate 501, allowing internal heat to be transferred to the cooling surface more quickly, greatly enhancing the heat transfer process. The sealed outer casing of the motor 503 ensures its safe operation in humid environments.

[0037] In a further preferred embodiment of the present invention, the cooling pipe 505 has an "S" shaped structure, with its top end communicating with the top space of the partition 5, and its bottom end having a liquid outlet 506 extending to the bottom of the cooling tower 3.

[0038] In this embodiment, the grease that has completed heat exchange enters the "S"-shaped cooling pipe 505 through the opening at the top of the baffle 5. The "S"-shaped structure further increases the flow path of the grease and the contact area with the cooling medium, achieving final deep cooling. Finally, the finished oil cooled to the predetermined temperature is stably discharged from the liquid outlet 506 located at the bottom of the cooling tower 3.

[0039] In a further preferred embodiment of the present invention, a heat-conducting sheet 507 is fixed on the bottom surface of the partition 5 at the position corresponding to the heat dissipation guide plate 501.

[0040] In this embodiment, the temperature-conducting plate 507 is made of a metal material with a high thermal conductivity. One end of it is tightly connected to the bottom surface of the partition plate 5, and the other end extends into the lower liquid collection chamber. This structure can quickly conduct the residual heat that was not completely carried away by the cooling water in the area of ​​the upper heat dissipation guide plate 501 to the lower-temperature grease in the liquid collection chamber, realizing the secondary balance and effective utilization of heat inside the system, and further improving the overall energy utilization efficiency.

[0041] In a further preferred embodiment of the present invention, the oil inlet of the centrifugal atomizing distributor 6 is connected to the heating tank 602 through a heat-insulated transport pipe 601, and a first circulation pump 604 is provided on the heat-insulated transport pipe 601; the heating tank 602 is provided with a feeding port 603.

[0042] In this embodiment, the crude oil to be treated is added to the heating tank 602 through the feed port 603 and preheated to the optimal temperature required for deodorization. Subsequently, the hot oil is pumped through the insulated transport pipe 601 into the centrifugal atomizing distributor 6 located at the top of the atomizing deodorization tower 2, powered by the first circulation pump 604. The insulated transport pipe 601 ensures minimal heat loss of the oil during transport.

[0043] In a further preferred embodiment of the present invention, the liquid collection hood 7 is a funnel-shaped structure, with multiple inclined liquid collection plates 702 rotatably fixed at its top by a certain ring 703, and a circulation conduit 701 connected to its bottom. The other end of the circulation conduit 701 extends to the outside of the atomizing deodorizing tower 2 and is connected to the heating tank 602.

[0044] In this embodiment, the inclined collection plate 702 effectively intercepts large droplets that are not fully atomized and guides them downwards along the wall of the funnel-shaped collection hood 7. The collected substandard oil is returned to the heating tank 602 via the circulation conduit 701 to participate in the preheating and atomization process again. This design forms an internal quality monitoring and circulation loop, ensuring that all oils must reach optimal atomization before participating in subsequent deodorization, thereby guaranteeing the uniformity and high standards of the final product quality. The top shaping ring 703 ensures that all collection plates 702 maintain optimal tilt angles and structural stability.

[0045] In summary, this utility model, through a series of innovative structures such as modular design, centrifugal atomization, cooling technology combining static spiral flow channels and dynamic turbulence, and internal heat recovery and mass circulation, successfully overcomes the three core defects of existing technologies: low deodorization efficiency, poor system reliability, and inconvenient maintenance. It provides a highly efficient, reliable, and easy-to-maintain flaxseed oil deodorization system.
