Description

Technical Field

[0001] This invention relates to the field of corn oil processing equipment technology, specifically a deodorization device for corn oil production. Background Technology

[0002] Deodorization is a crucial step in edible oil production. This is especially true for oils like corn oil, where deodorization not only removes unpleasant odors and improves sensory quality but also ensures the oil's hygiene, safety, and stability. However, traditional deodorization methods often suffer from low efficiency, high energy consumption, and uneven deodorization, failing to meet the high-efficiency, energy-saving, and environmentally friendly requirements of modern edible oil production.

[0003] Chinese patent application CN220724073U discloses a deodorizing device for corn oil, including a support frame, an oil storage tank fixedly connected to the top of the support frame, an oil guide tank fixedly connected to the top of the oil storage tank, a hollow shaft fixedly connected to the middle of the oil guide tank, a spiral oil guide plate fixedly connected to one end of the hollow shaft inside the oil guide tank, and multiple steam nozzles fixedly connected to the outer side and bottom of the hollow shaft. An oil-carrying mechanism is installed inside the oil storage tank to perform quantitative deodorization of the corn oil. The oil-carrying mechanism includes the support shaft. This invention relates to the field of corn oil processing technology. This invention utilizes the structural characteristics of the spiral oil guide plate to ensure sufficient contact between steam and corn oil, thereby initially forming a deodorizing operation for corn oil. It also allows the corn oil entering the oil storage tank to come into contact with steam in batches for deodorization, preventing the bottom layer of corn oil from failing to deodorize, thus improving the overall deodorization effect.

[0004] However, this corn oil production unit has the following drawbacks in actual use:

[0005] Existing corn oil deodorization equipment mainly utilizes the structural characteristics of spiral oil guide plates, which can greatly extend the path of corn oil inside the oil guide tank, thereby allowing steam to come into contact with the corn oil. However, since the corn oil flows along the spiral oil guide plates, its surface has the most contact with steam during the flow process. Due to the isolation effect of the outer layer of corn oil, the inner layer of corn oil in contact with the spiral oil guide plates has difficulty coming into contact with the corn oil, resulting in a long deodorization time and poor deodorization effect. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a deodorization device for corn oil production, achieved through the following technical solution:

[0007] A deodorization device for corn oil production includes a deodorization tower, an exhaust pipe, a deodorization component, and a stirring component. The exhaust pipe is integrally fixedly installed on the top of the deodorization tower. An oil inlet pipe and an oil outlet pipe are fixedly installed on the upper and lower parts of one side of the deodorization tower, respectively. The upper part of the inner wall of the deodorization tower is provided with the deodorization component, and the lower part of the inner wall of the deodorization tower is provided with the stirring component.

[0008] The deodorizing component includes:

[0009] A steam channel is fixedly installed in the middle of one side of the deodorization tower;

[0010] A booster pump is fixedly installed at the bottom of the other side of the deodorization tower;

[0011] The inlet pipe is fixedly installed at the inlet of the booster pump, and the inlet pipe passes horizontally through the deodorization tower and is fixedly connected to it;

[0012] The outlet pipe is fixedly installed at the outlet of the booster pump;

[0013] A connecting pipe is fixedly installed at the upper end of the liquid outlet pipe. The connecting pipe extends into the deodorization tower and is fixedly connected thereto. The end of the connecting pipe inside the deodorization tower is in a closed state. The connecting pipe is located above the steam channel.

[0014] The spray head is connected to a horizontally arranged pipe, and several evenly distributed spray heads are fixedly installed at the bottom of the connecting pipe.

[0015] Furthermore, the stirring assembly includes a short pipe, and one end of the liquid inlet pipe is integrally fixedly installed with the short pipe inside the deodorization tower, and a spiral blade is fixedly installed inside the short pipe.

[0016] Furthermore, a partition is fixedly installed inside the deodorization tower, and a through groove is opened in the center of the partition.

[0017] Furthermore, pressure relief pipes are fixedly installed on both sides of the partition, and the pressure relief pipes penetrate the partition vertically and are fixedly connected to it.

[0018] Furthermore, the center of the partition is recessed downwards in a funnel shape.

[0019] Furthermore, both the inlet pipe and the outlet pipe are equipped with valves.

[0020] Furthermore, the bottom of the deodorization tower is provided with a slag discharge port, and a sealing cap is provided on the slag discharge port. The sealing cap is threadedly connected to the slag discharge port, which facilitates the periodic cleaning of sediment and impurities inside the deodorization tower.

[0021] Furthermore, the outer wall of the deodorization tower is provided with a heat insulation layer.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This device achieves highly efficient deodorization by utilizing high-temperature steam in full contact with corn oil through a deodorization component. The steam temperature is controlled between 220℃ and 260℃, which effectively volatilizes odor molecules while avoiding adverse effects on the quality of the corn oil. Simultaneously, the dynamic stirring action of the stirring component enhances mass transfer efficiency, resulting in more uniform and thorough deodorization and improving overall deodorization efficiency.

[0024] 2. This device cleverly divides the interior of the deodorization tower into two independent zones by installing a partition. The upper zone is used to process corn oil that has already undergone preliminary deodorization, while the lower zone holds the corn oil to be processed. This design makes the deodorization process more orderly, avoids interference between corn oils at different processing stages, thereby optimizing the deodorization process and improving overall processing efficiency.

[0025] 3. The channel in the center of the baffle allows the treated corn oil to flow smoothly into the lower area and continue to participate in the deodorization reaction. This design not only promotes the circulation of the oil but also allows the corn oil to come into more complete contact with the high-temperature steam, thereby enhancing the deodorization effect. At the same time, the pressure relief pipes on both sides of the baffle also promote oil flow, contributing to the continuity of the overall deodorization process. Attached Figure Description

[0032] Example: A deodorization device for corn oil production

[0033] like Figure 1-4 As shown, a deodorization device for corn oil production has the following specific structure:

[0034] The deodorization tower 10 includes an exhaust pipe 20, a deodorization component 30, and a stirring component 40. The exhaust pipe 20 is integrally fixedly installed on the top of the deodorization tower 10. An oil inlet pipe 101 and an oil outlet pipe 102 are fixedly installed on the upper and lower parts of one side of the deodorization tower 10, respectively. The upper part of the inner wall of the deodorization tower 10 is provided with the deodorization component 30, and the lower part of the inner wall of the deodorization tower 10 is provided with the stirring component 40.

[0035] The deodorization component 30 includes: a steam channel 301, which is fixedly installed in the middle of one side of the deodorization tower 10; a booster pump 302, which is fixedly installed at the bottom of the other side of the deodorization tower 10 and is electrically connected to a power source; an inlet pipe 303, which is fixedly installed at the inlet of the booster pump 302, and extends laterally through and is fixedly connected to the deodorization tower 10, with the opening of the inlet pipe 303 extending into the deodorization tower 10; an outlet pipe 304, which is fixedly installed at the outlet of the booster pump 302; and a connecting pipe 305, which is connected to the outlet pipe 304. A connecting pipe 305 is fixedly installed at the upper end of 04. The connecting pipe 305 extends into the deodorization tower 10 and is fixedly connected thereto. The end of the connecting pipe 305 inside the deodorization tower 10 is in a closed state. The connecting pipe 305 is located above the steam channel 301. Spray heads 306 are fixedly installed at the bottom of the connecting pipe 305, with several evenly distributed spray heads 306. A grid plate 80 is fixedly installed in the upper part of the deodorization tower 10. By setting the grid plate 80, the flow rate of steam can be slowed down, so that the steam can fully contact the oil, promote the volatilization of odor molecules, and improve the deodorization effect.

[0036] The working principle described above is as follows:

[0037] When this device is in use, high-temperature steam enters the deodorization tower 10 through the steam channel 301. The steam temperature is set to 220℃-260℃. Then, through the cooperation of the booster pump 302, the inlet pipe 303, and the outlet pipe 304, the corn oil is sprayed out through the spray head 306, realizing the circulation of corn oil in the deodorization tower 10. By continuously spraying the corn oil, the corn oil can fully contact the high-temperature steam, promoting the volatilization of odor molecules and improving the deodorization effect of this device.

[0038] During operation, this device efficiently utilizes the full contact between high-temperature steam and corn oil to maximize the deodorization effect. Specifically, high-temperature steam is slowly injected into the deodorization tower 10 through steam channel 301. Taking advantage of the difference in volatilization points between corn oil and odor molecules, the steam temperature is controlled between 220℃ and 260℃. This temperature range ensures that the steam has sufficient heat energy to volatilize the odor molecules while avoiding excessively high temperatures that could adversely affect the quality of the corn oil.

[0039] The booster pump 302 works in close conjunction with the inlet pipe 303 and the outlet pipe 304 to form a closed-loop circulation system. After the booster pump 302 starts, it draws corn oil from the bottom of the deodorization tower 10 and delivers it to the outlet pipe 304 through the inlet pipe 303. During this process, the corn oil is pushed to the connecting pipe 305 under pressure.

[0040] The connecting pipe 305 is located above the steam channel 301. This arrangement ensures that the corn oil is fully preheated before being sprayed out and forms the optimal contact angle with the rising high-temperature steam.

[0041] Finally, the corn oil is sprayed out in a fine mist through the evenly distributed spray nozzles 306 at the bottom of the connecting pipe 305. This fine mist of corn oil forms a thin oil curtain inside the deodorization tower 10, thoroughly mixing and contacting with the high-temperature steam. During the continuous spraying process, the odor molecules in the corn oil rapidly evaporate under the action of the high-temperature steam, thus being effectively removed. Simultaneously, this circulating spraying method ensures that the corn oil is heated evenly, improving deodorization efficiency and ensuring the excellent deodorization effect of this device.

[0042] The stirring assembly 40 includes a short pipe 401. The short pipe 401 is integrally fixedly installed at one end of the liquid inlet pipe 303 within the deodorization tower 10. A spiral blade 402 is fixedly installed inside the short pipe 401. When the booster pump 302 pumps liquid through the liquid inlet pipe 303, the liquid flows through the short pipe 401. Due to the fixed installation of the spiral blade 402 inside the short pipe 401, the liquid rotates as it flows past the spiral blade 402, thus stirring the corn oil at the bottom of the deodorization tower 10. This ensures thorough mixing of the corn oil and the deodorizing agent, improving the deodorization effect. The design of the stirring assembly 40 achieves dynamic stirring of the corn oil, enhancing the mass transfer efficiency during the deodorization process, resulting in more uniform and thorough deodorization, and improving the working efficiency and deodorization effect of the deodorization device.

[0043] A partition 50 is fixedly installed inside the deodorization tower 10, and a through groove 501 is opened in the center of the partition 50. The partition 50 divides the interior of the deodorization tower 10 into upper and lower areas. The corn oil in the upper area has undergone steam deodorization treatment, and the corn oil in the lower area is the corn oil to be treated. The corn oil to be treated circulates in the deodorization tower 10 through the cooperation of the stirring assembly 40, the liquid inlet pipe 303, the booster pump 302, and the liquid outlet pipe 304. Then, the corn oil in the upper area can pass through the through groove 501 in the center of the partition 50 and enter the lower area to continue to participate in the deodorization reaction.

[0044] Pressure relief pipes 502 are fixedly installed on both sides of the partition 50. The pressure relief pipes 502 vertically penetrate the partition 50 and are fixedly connected to it. During the deodorization process, the pressure relief pipes 502 can promote the flow of corn oil between the upper and lower areas, facilitate the downward flow of corn oil in the upper part, help the uniformity of the overall deodorization effect, and ensure the smooth progress of the deodorization process.

[0045] The baffle 50 is recessed downwards in a funnel shape. The funnel-shaped baffle 50 design facilitates the smooth flow of the corn oil processed in the upper part into the lower part through the channel 501, reducing the resistance to oil flow and improving circulation efficiency.

[0046] Both the inlet pipe 303 and the outlet pipe 304 are equipped with valves 60. The valves 60 allow for convenient control of the flow in the inlet and outlet pipes 303 and 304, facilitating the shut-off of oil flow during equipment maintenance, cleaning, or adjustment of process parameters. This design improves the operability and flexibility of the equipment, enabling rapid adjustments and maintenance based on actual production needs.

[0047] The deodorization tower 10 has a slag discharge port 70 at its bottom, and a sealing cap 701 is provided on the slag discharge port 70. The sealing cap 701 is threadedly connected to the slag discharge port 70, facilitating the periodic cleaning of sediment and impurities inside the deodorization tower 10. During the deodorization process, impurities and sediments in the corn oil will accumulate at the bottom of the deodorization tower 10. By periodically opening the sealing cap 701, these sediments can be easily discharged. This design ensures the cleanliness of the deodorization tower, extends the service life of the equipment, and improves the quality of the corn oil.

[0048] The outer wall of the deodorization tower 10 is equipped with an insulation layer. The insulation layer is made of rock wool or aluminum silicate fiber material, which effectively reduces heat loss, improves deodorization efficiency, and ensures a safe and comfortable operating environment.
