Description

Technical Field

[0001] This invention belongs to the field of edible oil processing technology, and specifically relates to a fine filtration device for low-temperature deodorization of edible oil. Background Technology

[0002] Edible oil extracted from oilseeds is called crude oil. Crude oil contains impurities such as phospholipids, waxes, free fatty acids, pigments, off-flavor substances, and a small amount of protein colloids. In order to obtain high-quality edible oil, it needs to go through refining processes such as degumming, deacidification, decolorization, and deodorization. Deodorization is an important step, the purpose of which is to remove off-flavor substances from the oil. Fine filtration after deodorization is to remove any impurities that may be generated, ensuring the purity and quality of the edible oil.

[0003] The heat treatment method used in the existing deodorization process has obvious drawbacks. The core problem is that impurities are prone to accumulate during the process. A large number of impurities adhere to the inner wall of the equipment and the surface of the filter components, which not only affects the heat transfer efficiency, but also significantly hinders the flow of materials. This accumulation effect directly leads to the forced slowdown of the processing flow and the disruption of the production rhythm. This not only reduces the processing volume per unit time, but also may cause a hidden decline in the quality of oils due to the extended heating time of the materials, making it difficult to meet the high-efficiency and high-quality requirements of modern edible oil processing. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fine filtration device for low-temperature deodorization of edible oils.

[0005] To achieve the above objectives, the present invention provides a fine filtration device for low-temperature deodorization of edible oil, comprising a deodorizing cylinder, a cover plate, an oil inlet pipe, and a high-pressure steam pipe. The oil inlet pipe is movably disposed inside the cover plate and the inside of the deodorizing cylinder is provided with two arc-shaped contact plates. The tops of the two arc-shaped contact plates are both arc-shaped. A rotating scraping mechanism is provided inside the deodorizing cylinder for scraping off the edible oil outside the arc-shaped contact plates. In the above technical solution, a horizontal pipe is further provided at the bottom end of the oil inlet pipe, and spray heads are provided at both ends of the horizontal pipe, with the two spray heads corresponding to the outer sides of the two arc-shaped contact plates respectively.

[0006] In the above technical solution, the rotary scraping mechanism further includes a connecting cylinder that connects the inner side of the deodorizing cylinder to a high-pressure steam pipe. A hollow plate is provided on the inner side of the deodorizing cylinder, and a connecting pipe is provided between the hollow plate and the connecting cylinder. Multiple exhaust grooves are provided on the side of the hollow plate. In the above technical solution, a rotating rod is movably arranged inside the connecting cylinder, and multiple fan blades are arranged on the outer side of the rotating rod.

[0007] In the above technical solution, a collar is further provided on the outer side of the rotating rod, and two connecting plates are provided on the outer side of the collar. Baffles are provided at the bottom of the two connecting plates, and the two baffles are movably disposed on the inner side of the connecting cylinder.

[0008] In the above technical solution, a rotating plate is movably provided at the end of the rotating rod, a scraper is provided at the top of the rotating plate and movably connected to the outer side of the arc-shaped contact plate, a horizontal plate is provided on the inner side of the arc-shaped contact plate, and a support rod connected to the connecting cylinder is provided at the bottom of the horizontal plate.

[0009] Compared with the prior art, the present invention has the following beneficial effects: by cooperating with the oil inlet pipe, the horizontal pipe and the spray head, edible oil can be evenly sprayed on the surface of the arc-shaped contact plate, increasing the heating area. The rotating scraping mechanism can scrape off the grease and impurities on the outside of the arc-shaped contact plate in real time, avoiding accumulation and obstructing the flow, ensuring processing efficiency, increasing the processing capacity per unit time, and meeting the dual requirements of high efficiency and high quality in modern edible oil processing.

[0012] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] like Figures 1-5The illustrated low-temperature deodorizing fine filtration equipment for edible oil includes a deodorizing cylinder 1, a cover plate 2, an oil inlet pipe 3, and a high-pressure steam pipe 4. The oil inlet pipe 3 passes through the cover plate 2 and is movably disposed inside the deodorizing cylinder 1. The deodorizing cylinder 1 is provided with two arc-shaped contact plates 5 inside, and the tops of the two arc-shaped contact plates 5 are both arc-shaped. The deodorizing cylinder 1 is provided with a rotating scraping mechanism 6 inside, which is used to scrape off the edible oil outside the arc-shaped contact plates 5. The deodorizing cylinder 1 serves as the core processing chamber, providing a closed space for grease deodorization. The cover plate 2 provides sealing and component installation support. The oil inlet pipe 3 penetrates the cover plate 2 and extends deep inside, allowing for precise delivery of the grease to be processed. Its movable design facilitates maintenance and adjustment. Two arc-shaped contact plates 5 form a symmetrical processing surface. The top arc design guides the flow of grease. The rotating scraping mechanism 6 operates in real time, reducing impurity retention at the source and ensuring continuous processing.

[0014] A horizontal pipe 7 is installed at the bottom of the oil inlet pipe 3. Spray heads 8 are installed at both ends of the horizontal pipe 7. The two spray heads 8 correspond to the outer sides of the two arc-shaped contact plates 5 respectively. The horizontal pipe 7 at the bottom of the oil inlet pipe 3 and the spray heads 8 at both ends constitute a precise oil distribution system. The spray heads 8 correspond to the outer sides of the arc-shaped contact plates 5, atomizing the grease into fine droplets and evenly covering the surface of the plates 2. This design greatly increases the contact area between the grease and the heat source, improves the heat exchange efficiency, and avoids local oil accumulation, creating favorable conditions for subsequent scraping operations and ensuring that the deodorization reaction is sufficient and stable.

[0015] The rotary scraping mechanism 6 includes a connecting cylinder 63 that connects the inner side of the deodorizing cylinder 1 to the high-pressure steam pipe 4. A hollow plate 61 is provided on the inner side of the deodorizing cylinder 1. A connecting pipe 62 is provided between the hollow plate 61 and the connecting cylinder 63. Multiple exhaust slots 66 are provided on the side of the hollow plate 61. A rotating rod 610 is movably installed inside the connecting cylinder 63, and multiple fan blades 612 are installed on the outside of the rotating rod 610. The rotating rod 610 and the fan blades 612 inside the connecting cylinder 63 constitute a power conversion component. When high-pressure steam impacts the fan blades 612, it converts thermal energy into mechanical energy to drive the rotating rod 610 to rotate. This design does not require an additional power source and uses the steam required for the process to achieve energy recovery, which simplifies the structure and reduces energy consumption. The stable rotation of the rotating rod 610 provides continuous power output for the subsequent scraping and baffle 69 operation.

[0016] A collar 613 is sleeved on the outer side of the rotating rod 610. Two connecting plates 611 are provided on the outer side of the collar 613. Baffles 69 are provided at the bottom of the two connecting plates 611 respectively. Both baffles 69 are movably disposed on the inner side of the connecting cylinder 63.

[0017] A rotating plate 67 is movably provided at the end of the rotating rod 610. A scraper 68 is provided at the top of the rotating plate 67 and is movably connected to the outer side of the arc-shaped contact plate 5. A horizontal plate 64 is provided on the inner side of the arc-shaped contact plate 5. A support rod 65 connected to the connecting cylinder 63 is provided at the bottom of the horizontal plate 64. The rotating plate 67 at the end of the rotating rod 610 rotates synchronously with the rod, and the top scraper 68 slides close to the outside of the arc-shaped contact plate 5 to scrape off the attached grease and impurities in real time, preventing accumulation and crusting. The horizontal plate 64 on the inner side of the arc-shaped contact plate 5 and the support rod 65 form a stable support structure to ensure the flatness of the plate surface and the fit of the scraper 68, which maintains the processing efficiency, extends the service life of the equipment, and reduces the frequency of downtime for cleaning.

[0018] Working principle: When using this device, the edible oil to be deodorized first comes out from the oil inlet pipe 3, and is sprayed onto the outer surface of the arc-shaped contact plate 5 through the horizontal pipe 7 and the spray head 8. Hot air enters the interior of the connecting cylinder 63 through the high-pressure steam pipe 4. The connecting cylinder 63 is equipped with multiple fan blades 612, which are pushed to rotate, causing the rotating rod 610 to rotate. The hot air enters the interior of the connecting pipe 62 through the connecting cylinder 63, and is then sprayed out through the exhaust groove 66 opened on the hollow plate 61. At this time, the outer surface of the arc-shaped contact plate 5 is sprayed with edible oil, thus deodorizing it. After completion, the rotating rod 610 will rotate, which drives the rotating plate 67 at the end to rotate. The rotating plate 67 drives the scraper 68 to rotate on the outer surface of the arc-shaped contact plate 5, scraping off the edible oil that has been deodorized from the outer surface of the arc-shaped contact plate 5, thereby performing efficient edible oil deodorization.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
