Description

Technical Field

[0001] The utility model relates to the technical field of edible oil processing, in particular to a multi-stage deodorizing tower. Background Art

[0002] In the production process of edible oil, the raw oil often contains some unwanted impurities and odorous substances, which may include low molecular aldehydes, ketones, free fatty acids, unsaturated hydrocarbons, etc. These substances will not only affect the flavor of the edible oil, but may also have a negative impact on its quality; therefore, in order to produce high-quality edible oil, it needs to be purified through a refining process, and deodorization is a very critical step in the refining process. The deodorization tower utilizes the fact that small molecular odorous organic matter in oils and fats is more volatile than triglycerides under high temperature and negative pressure. When water vapor passes through the odorous oils and fats, the water vapor is saturated with the volatile odorous components and escapes in proportion to their partial pressure, thereby achieving the purpose of removing the odor.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 A multi-stage deodorization tower in this embodiment includes a processing chamber 1, a processing chamber 2 and a fixed box 3. A steam connecting pipe 4 is arranged on the right side of the fixed box 3, an auxiliary mechanism 5 is arranged inside the fixed box 3, and an oil inlet pipe 6 is arranged on the left side of the processing chamber 1.

[0023] A steam outlet pipe 101 is fixedly installed on the inner top of the processing chamber 1, two diverter plates 102 are fixedly installed inside the processing chamber 1, and a rotating drum 201 is rotatably installed inside the processing chamber 22, and the outer surface of the rotating drum 201 is evenly provided with air outlet holes 202.

[0024] A group of steam nozzles are installed at equal distances at the bottom of the steam outlet pipe 101. The two diverter plates 102 are both inclined and have flow holes. The diverter plates 102 allow the oil to flow downward while dripping through the flow holes, increasing the chance of contact between the oil and the steam, which helps to improve the mass transfer efficiency. The steam inside the drum 201 is ejected through the air outlet 202.

[0025] A steam inlet pipe is fixedly installed on the right side of the steam connecting pipe 4 , one end of the steam connecting pipe 4 is connected to the steam outlet pipe 101 , and the other end of the steam connecting pipe 4 is connected to the drum 201 .

[0026] The steam enters the steam connecting pipe 4 through the steam inlet pipe, and is then transported to the steam outlet pipe 101 and the drum 201 through the steam connecting pipe 4 .

[0027] A connecting port is provided between processing chamber 1 and processing chamber 2, a discharge pipe is provided on the left side of processing chamber 2, and a valve is provided on the discharge pipe. The oil liquid that has undergone initial treatment in processing chamber 1 enters processing chamber 2 2 through the connecting port for further treatment, and is discharged through the discharge pipe after the treatment is completed.

[0028] The auxiliary mechanism 5 includes a motor 501, the motor 501 is fixedly installed on the top of the fixed box 3, a worm 502 extending to the inside of the processing chamber 1 is fixedly installed at the output shaft of the motor 501, a fan blade 503 is fixedly installed at the bottom of the worm 502, a worm wheel 504 is meshed with the outer surface of the worm 502, a cross bar 505 is fixedly installed on the right end of the worm wheel 504, and a transmission assembly 506 is arranged between the cross bar 505 and the rotating drum 201.

[0029] The transmission assembly 506 includes a driving pulley 601, the outer surface of the cross bar 505 is fixedly mounted with the driving pulley 601, the outer surface of the rotating drum 201 is fixedly mounted with a driven pulley 602, and a transmission belt 603 is installed between the outer surfaces of the driving pulley 601 and the driven pulley 602.

[0030] A fixing block is fixedly mounted on the inner top wall of the fixing box 3, and the fixing block improves the stability of the cross bar 505 when it rotates.

[0031] Under the action of the auxiliary mechanism 5, by starting the motor 501, the fan blades 503 and the drum 201 can be driven to rotate at the same time. The rotation of the fan blades 503 can evenly diffuse the steam in the steam outlet pipe 101 to the interior of the processing chamber 1, and the rotation of the drum 201 can evenly diffuse the steam to the interior of the processing chamber 2 2, so that the steam and oil in the processing chamber 1 1 and the processing chamber 2 2 can be in contact with a large area, so as to improve the deodorization efficiency.

[0032] When implementing, follow these steps:

[0033] 1) When the oil enters the processing chamber 1 from the oil inlet pipe 6, it will first flow along the top diverter plate 102 to the bottom diverter plate 102, and at the same time, the oil will drip down through the flow hole and enter the interior of the processing chamber 2 through the connection port;

[0034] 2) When the oil enters the processing chamber 1, the steam is introduced into the steam connecting pipe 4 through the steam inlet pipe, and then introduced into the steam outlet pipe 101 and the rotating drum 201 through the steam connecting pipe 4. The steam in the steam outlet pipe 101 is sprayed out through the steam nozzle, and the steam in the rotating drum 201 is sprayed out through the air outlet 202;

[0035] 3) At the same time, when the motor 501 is started, the motor 501 drives the worm 502 to rotate, and the worm 502 drives the fan blade 503 to rotate, so that the steam sprayed from the steam outlet pipe 101 is widely diffused to the inside of the processing chamber 1, and the oil is deodorized for the first time;

[0036] 4) The worm 502 rotates and drives the drum 201 to rotate through the transmission assembly 506. The drum 201 drives the air outlet 202 to rotate and spray steam, thereby performing a second deodorization treatment on the oil.

[0037] 5) After the treatment is completed, open the valve and the treated oil will be discharged through the discharge pipe.

[0038] In summary, the multi-stage deodorization tower, by arranging two diverter plates 102 and opening flow holes on the two diverter plates 102, allows the oil to drip downward through the flow holes while flowing, thereby slowing down the oil, allowing the steam sprayed from the steam outlet pipe 101 to be in contact with the oil for a longer time, and under the rotation of the fan blades 503, the steam sprayed from the steam outlet pipe 101 is evenly diffused, thereby increasing the contact area between the steam and the oil, thereby improving the deodorization effect.

[0039] Furthermore, by setting up the drum 201 and opening the air outlet 202 on the drum 201, the uniform distribution of steam is promoted during the rotation of the drum 201, and the steam is ensured to be in full contact with the oil. In addition, combined with the design of the processing chamber 1 and the processing chamber 2 2, the oil will undergo multiple deoxygenation treatments, thereby significantly improving the deodorization effect.
