Description

Technical Field

[0001] This utility model belongs to the field of deodorization technology in oil production, and particularly relates to a deodorization tower for oil production. Background Technology

[0002] In the food industry, especially in edible oil production, deodorization is a crucial step that directly impacts the quality and taste of the final product. Traditional deodorization technologies mainly include vacuum distillation and chemical deodorization. While these methods can remove odors from oils to some extent, they may also remove beneficial components, affecting the overall quality of the oil. With the increasing consumer demand for natural and healthy foods, the market is increasingly seeking new technologies that can effectively deodorize while retaining more nutrients. Currently, the most common deodorization method in oil production is high-temperature, short-time vacuum distillation, which uses heating to volatilize low-boiling-point compounds, thereby removing odors. Other methods include activated carbon adsorption or the use of chemical reagents. However, vacuum distillation typically requires high temperatures (around 250°C), which not only consumes a large amount of energy but also may lead to the loss of some beneficial substances due to prolonged high-temperature treatment. Activated carbon adsorption faces challenges such as high adsorbent regeneration costs and unstable efficiency. Chemical reagent deodorization methods are prone to introducing new harmful residues, failing to meet modern food safety standards. Existing deodorization technologies for oil production generally suffer from high energy consumption, loss of beneficial components, low processing efficiency, and potential safety hazards, failing to meet the current market demand for efficient, environmentally friendly, and safe deodorization technologies. Furthermore, existing technologies do not recover the steam after use, resulting in direct emissions and environmental pollution. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned technical problems by providing an oil production deodorization tower that condenses and recovers steam, achieving an environmentally friendly effect.

[0004] In view of this, the present invention provides an oil production deodorization tower including a support frame, a deodorization tank disposed on the support frame; an oil inlet pipe disposed at the top of the deodorization tank; a vacuum device connected to the top of the deodorization tank; an electric heating tube disposed inside the deodorization tank; a steam injector disposed inside the deodorization tank; a steam recovery box connected to the top of the deodorization tank; a condenser connected to the deodorization tank and the steam recovery box; and an oil outlet valve disposed at the bottom of the deodorization tank.

[0005] In this technical solution, a vacuum device performs vacuum treatment on the inside of the deodorizing tank. After the treatment, the edible oil to be deodorized flows into the deodorizing tank through the oil inlet pipe. The electric heating tube heats the edible oil in the deodorizing tank to a suitable temperature. Hot steam is added into the deodorizing tank through a steam injector. The steam carries out the odor factors in the edible oil. The steam then enters the recovery steam box for condensation and recovery.

[0006] In the above technical solution, furthermore, a cooling partition is provided on the inner wall of the deodorizing tank. The cooling partition is connected to a first inlet pipe. One end of the first inlet pipe passes through the outer wall of the deodorizing pipe and is connected to the cooling partition. The other end of the first inlet pipe is connected to a first valve. The valve is connected to a first tee pipe. One end of the first tee pipe is connected to a condenser, and the other end is connected to a second valve. The second valve is connected to a second inlet pipe. The other end of the second inlet pipe is connected to a steam recovery box. The cooling partition is connected to a first outlet pipe. The first outlet pipe is connected to a second tee pipe. One end of the tee pipe is connected to the condenser, and the other end is connected to the second outlet pipe. The second outlet pipe is connected to the steam recovery box.

[0007] In this technical solution, when steam is added to the edible oil, the first valve is closed and the second valve is opened, allowing the cooling medium to flow into the steam recovery tank for temperature exchange, enabling the steam recovery tank to condense and recover the steam. After deodorization, when the electric heating element stops heating and steam is no longer added to the deodorization tank, the first valve is opened and the second valve is closed, allowing the cooling medium to flow into the cooling and insulation layer for temperature exchange with the edible oil. Once the edible oil reaches a certain temperature, the oil outlet valve is opened, and the edible oil proceeds to the next process. The steam carries odor-causing agents and is condensed and recovered, preventing environmental pollution. The steam recovery tank and the cooling of the edible oil share a single cooler, which not only staggers the cooling times but also avoids resource waste.

[0008] In the above technical solution, the vacuum device is further connected to a vacuum tube, the vacuum tube is connected to a pressure valve, and the pressure valve is connected to the top of the deodorizing tank.

[0009] In this technical solution, a vacuum device evacuates the deodorizing tank to a vacuum state through a vacuum tube. When the air pressure reaches a predetermined value, the air pressure valve closes. When the air pressure inside the deodorizing tank changes, the air pressure valve opens, which is controlled by the vacuum device. The vacuum device is existing and well-known technology and will not be described in detail.

[0010] In the above technical solution, the steam injector further includes an air inlet pipe, which passes through the side wall of the deodorizing tank and is connected to an air outlet cylinder. The air outlet cylinder is fixedly installed inside the deodorizing tank, and air nozzles are arranged in a circumferential array on the outer wall of the air outlet cylinder.

[0011] In this technical solution, hot steam enters the outlet pipe from the inlet pipe and is released into the deodorizing tank through the jet nozzle. This not only introduces hot steam into the deodorizing tank but also ensures that the edible oil in the deodorizing tank is evenly affected by the steam, causing the edible oil to boil.

[0012] In the above technical solution, the recovered steam box further includes a recovery pipe, one end of which is connected to the top of the deodorization tank and the other end is connected to a trapezoidal cover. The trapezoidal cover is fixedly installed on the box body, and the box body is fitted with a temperature exchange pipe.

[0013] In this technical solution, the hot steam carrying the odor factor enters the chamber through the air inlet pipe. The chamber is cooled by the cooling medium in the temperature exchange pipe, so that the steam is cooled to form water. The chamber collects the water, which not only saves space but also protects the environment.

[0014] In the above technical solution, the outer wall of the box is further abutted against the temperature exchange tube, and the temperature exchange tube is set in a spiral shape.

[0015] In this technical solution, the temperature exchange tube is in contact with the outer wall of the box at its maximum area, which improves the thermal conductivity and the efficiency of steam condensation into water for recycling.

[0016] In the above technical solution, the condenser further includes a heat-conducting pipe, which is fixedly installed in a mounting frame. A heat-conducting plate is linearly arrayed in the mounting frame, and the heat-conducting plate intersects with the outer wall of the heat-conducting pipe. A cooling fan is fixedly installed on one side of the mounting frame.

[0017] In this technical solution, the cooling medium after temperature exchange flows into the heat pipe. A heat-conducting plate is embedded in the outer wall of the heat pipe, and heat diffuses onto the heat-conducting plate. A cooling fan cools the heat-conducting plate, and the temperature of the cooling medium also decreases. This provides a circulating cooling medium for the recovery steam box and the cooling partition.

[0018] The beneficial effects of this utility model are:

[0019] 1. By setting up a steam recovery box, the steam recovery box and the cooling of cooking oil share a single cooler, which not only staggers the cooling time but also avoids the waste of resources.

[0020] 2. By setting up a cooling insulation layer, the cooling medium flows into the cooling insulation layer and exchanges temperature with the edible oil. When the edible oil cools down to a certain temperature, the oil outlet valve is opened, and the edible oil enters the next process.

[0021] 3. By installing a condenser, a circulating cooling medium is provided for the recovery steam box and the cooling partition. Attached Figure Description

[0034] Example 1:

[0035] This embodiment provides a deodorization tower for oil production, such as... Figure 1As shown, the device includes a support frame 1, a deodorizing tank 2 mounted on the support frame 1, an oil inlet pipe 3 located at the top of the deodorizing tank 2, a vacuum device 4 connected to the top of the deodorizing tank 2, an electric heating element 6 located inside the deodorizing tank 2, a steam injector located inside the deodorizing tank 2, a steam recovery box 8 connected to the top of the deodorizing tank 2, a condenser connected to both the deodorizing tank 2 and the steam recovery box 8, and an oil outlet valve 5 located at the bottom of the deodorizing tank 2. Vacuum device 4 performs vacuum treatment on the inside of deodorizing tank 2. After treatment, the edible oil to be deodorized flows into deodorizing tank 2 through oil inlet pipe 3. Electric heating tube 6 heats the edible oil in deodorizing tank 2 to a suitable temperature. Hot steam is added into deodorizing tank 2 through steam injector. The steam carries out the odor factors in the edible oil. The steam then enters the recovery steam box 8 for condensation and recovery.

[0036] like Figure 2-4 As shown, a cooling partition 26 is provided on the inner wall of the deodorizing tank 2. The cooling partition 26 is connected to a first inlet pipe 17. One end of the first inlet pipe 17 passes through the outer wall of the deodorizing pipe and connects to the cooling partition 26. The other end of the first inlet pipe 17 is connected to a first valve 18. The valve is connected to a first tee pipe 21. One end of the first tee pipe 21 is connected to the condenser, and the other end is connected to a second valve 19. The second valve 19 is connected to a second inlet pipe 20. The other end of the second inlet pipe 20 is connected to a steam recovery box. The cooling partition 26 is connected to a first outlet pipe 22. The first outlet pipe 22 is connected to a second tee pipe 23. One end of the tee pipe is connected to the condenser, and the other end is connected to a second outlet pipe 24. The second outlet pipe 24 is connected to the steam recovery box. When steam is added to the edible oil, the first valve 18 is closed and the second valve 19 is opened. The cooling medium flows into the steam recovery box, exchanging temperature with the steam recovery box, allowing the steam recovery box to condense and recover the steam. After deodorization is complete, when the electric heating element 6 stops heating and steam is no longer added to the deodorization tank 2, the first valve 18 is opened and the second valve 19 is closed. The cooling medium flows into the cooling and insulation layer to exchange temperature with the edible oil. When the edible oil cools to a certain temperature, the oil outlet valve 5 is opened, and the edible oil enters the next process. The steam carries odor factors and is condensed and recovered, avoiding environmental pollution. The steam recovery tank and the cooling of the edible oil share a single cooler, which not only staggers the cooling time but also avoids resource waste.

[0037] like Figure 2As shown, the vacuum device 4 is connected to a vacuum tube 401, which in turn is connected to a pressure valve 402. The pressure valve 402 is connected to the top of the deodorizing tank 2. The vacuum device 4 evacuates the deodorizing tank 2 into a vacuum state through the vacuum tube 401. When the pressure reaches a predetermined value, the pressure valve 402 closes. When the pressure inside the deodorizing tank 2 changes, the pressure valve 402 opens, controlled by the vacuum device 4. The vacuum device 4 is existing known technology and will not be described in detail.

[0038] like Figure 2 As shown, the steam injector includes an air inlet pipe 7, which passes through the side wall of the deodorizing tank 2 and is connected to an air outlet pipe 12. The air outlet pipe 12 is fixedly installed inside the deodorizing tank 2, and air nozzles 13 are arranged in a circumferential array on the outer wall of the air outlet pipe 12. Hot steam enters the air outlet pipe 7 from the air inlet pipe 7 and is released into the deodorizing tank 2 through the air nozzles 13. This not only introduces hot steam into the deodorizing tank 2, but also ensures that the cooking oil in the deodorizing tank 2 is evenly affected by the steam, causing the cooking oil to boil.

[0039] like Figure 3 As shown, the steam recovery box 8 includes a recovery pipe 14, one end of which is connected to the top of the deodorizing tank 2, and the other end is connected to a trapezoidal cover 15. The trapezoidal cover 15 is fixedly installed on the box body, and the box body is fitted with a temperature exchange pipe 16. The hot steam carrying the odor factors enters the box body through the air inlet pipe 7. The box body is cooled by the cooling medium in the temperature exchange pipe 16, causing the steam to cool and form water. The box body collects the water, which not only saves space but also protects the environment.

[0040] like Figure 3 As shown, the outer wall of the chamber abuts against the temperature exchange tube 16, which is spirally shaped. The maximum area of ​​the temperature exchange tube 16 abuts against the outer wall of the chamber, improving thermal conductivity and increasing the efficiency of steam condensation into water for recycling.

[0041] like Figure 5 As shown, the condenser includes a heat pipe 10, which is fixedly mounted within a mounting bracket 11. A heat-conducting plate 9 is linearly arrayed within the mounting bracket 11, intersecting with the outer wall of the heat pipe 10. A cooling fan 25 is fixedly mounted on one side of the mounting bracket 11. After temperature exchange, the cooling medium flows into the heat pipe 10. The outer wall of the heat pipe 10 is embedded with the heat-conducting plate 9, and heat diffuses onto the heat-conducting plate 9. The cooling fan 25 cools the heat-conducting plate 9, thus reducing the temperature of the cooling medium. This provides a circulating cooling medium for the recovery steam box 8 and the cooling partition 26.

[0042] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
