Description

Technical Field

[0001] The invention relates to the technical field of cottonseed oil production, in particular to a deodorizing device and a method for cottonseed oil production. Background Art

[0002] There are two production processes for cottonseed oil: pressing and extraction. Pressing uses mechanical pressing to extract cottonseed oil from cottonseeds. Extraction, on the other hand, uses the principle of solvent and oil miscibility to extract cottonseed oil from processed cottonseed meal.

[0003] The cottonseed oil that has just been produced has a strong odor, so it needs to be deodorized. The traditional deodorization device heats the cottonseed oil and then injects high-temperature steam into the tank where the cottonseed oil is stored. The above method can greatly improve the taste of the cottonseed oil.

[0004] However, after high-temperature steam is injected into the tank body, the excess gas inside it needs to be pumped out. Therefore, a vacuum pump is needed. An air pipe is installed between the vacuum pump and the tank body, and then the air pipe is used to pump air into the tank body. However, during the pumping process, the position of the air inlet of the air pipe has a temperature difference with other positions of the tank body due to long-term gas exchange, which causes condensation water to appear on the wall of the air inlet pipe. When the condensation water drips down and enters the cottonseed oil, it will affect the quality of the cottonseed oil. At the same time, the existing high-temperature steam is generally injected into the tank body through an aeration pipe. The aeration pipe is generally installed at the bottom of the tank body, which is prone to local aeration, resulting in a general aeration effect. It requires long-term stirring to achieve an effective deodorization effect. Therefore, we propose a deodorization device and method for cottonseed oil production. Summary of the Invention

[0020] A method for a deodorizing device for cottonseed oil production comprises the following steps:

[0021] Step 1: First, use the feed pipe to inject cottonseed oil into the interior of the processing tank, and then use the liquid inlet pipe to inject the heated high-temperature medium into the interior of the first spiral heating tube, so that the first spiral heating tube quickly heats the cottonseed oil inside the processing tank;

[0022] Step 2: Use the air inlet pipe to pump high-temperature steam into the interior of the aeration pipe. The high-temperature steam is injected into the cottonseed oil through multiple microporous aeration heads on the outer wall of the aeration pipe. The spiral aeration pipe cooperates with the multiple microporous aeration heads to perform aeration of the high-temperature steam inside the processing tank.

[0023] Step 3: Turn on the drive motor, and the driving end of the drive motor drives the stirring rod to rotate, thereby causing the multiple stirring blades on the outside of the stirring rod to rotate, thereby stirring the high-temperature cottonseed oil inside, accelerating the aeration and deodorization of the cottonseed oil;

[0025] Step 5: When the stirring rod rotates, it drives the reciprocating screw at its top to rotate accordingly, and then drives the fixed sleeve and the lifting rod to perform vertical reciprocating motion through the nut seat, so that the collecting ring and the movable sleeve move vertically at the air inlet and the air extraction pipe respectively. When the movable sleeve moves, the condensed water generated on the inner wall of the air extraction pipe and the condensed water on the inner wall of the movable sleeve itself slide downward, so that the condensed water falls into the collecting ring for collection;

[0026] Step 6: After the cottonseed oil is deodorized, the cottonseed oil is discharged outwards through the discharge port, and then the air is blown into the air inlet through the exhaust pipe to blow out the condensed water in the collection ring and dry it.

[0027] The present invention discloses a deodorizing device and method for cottonseed oil production, which have the following beneficial effects:

[0028] 1. The deodorizing device for cottonseed oil production utilizes an air inlet pipe to pump high-temperature steam into the interior of the aeration pipe. Since the aeration pipe is spirally installed on the outer peripheral wall of the first spiral heating pipe, the spiral aeration pipe cooperates with multiple microporous aeration heads to perform range aeration on the high-temperature steam in the processing tank, thereby increasing the aeration effect of the high-temperature steam. The high-temperature medium inside the first spiral heating pipe enters the second spiral heating pipe through the connecting pipe, and the second spiral heating pipe is spirally installed on the outer side of the air inlet, so that the second spiral heating pipe can heat the pipe wall of the air inlet, so that the pipe wall of the air inlet is in a state of higher temperature, thereby preventing the gas from forming condensed water on the pipe wall of the air inlet. At the same time, the reciprocating screw is driven to rotate by the stirring rod, thereby causing the collecting ring and the movable sleeve to move vertically at the air inlet and the exhaust pipe respectively, pushing the condensed water generated on the inner wall of the exhaust pipe and the condensed water on the inner wall of the movable sleeve itself to slide downward, thereby causing the condensed water to fall into the collecting ring for collection.

[0029] 2. The deodorizing device for cottonseed oil production utilizes a stirring mechanism to start a driving motor. The driving end of the driving motor drives the stirring rod to rotate, thereby causing multiple stirring blades on the outside of the stirring rod to rotate, thereby stirring the high-temperature cottonseed oil inside, accelerating the aeration and deodorization speed of the cottonseed oil. Because the end of the feed pipe is above the first spiral heating pipe, the cottonseed oil entering the processing tank from the feed pipe can cover the first spiral heating pipe. At the same time, the end of the feed pipe is below the exhaust pipe, thereby preventing the cottonseed oil from contacting the exhaust pipe. The flange installed at the ends of the feed pipe and the discharge port outside the discharge port facilitates the connection of the feed pipe and the pipeline outside the discharge port.

[0030] 3. The deodorizing device for cottonseed oil production uses a feed pipe to inject cottonseed oil into the interior of a processing tank, then uses a liquid inlet pipe to inject a heated high-temperature medium into the interior of a first spiral heating tube, and then uses the high-temperature medium to heat the tube wall of the first spiral heating tube. The spiral first spiral heating tube quickly heats the cottonseed oil inside the processing tank, and a thermal insulation jacket is installed on the outside of part of the liquid inlet pipe and part of the air inlet pipe. The thermal insulation jacket insulates the steam inside the air inlet pipe. During the flow of high-temperature steam in the aeration pipe, the special-shaped tube cavity is used to increase the contact area between the high-temperature steam and the tube wall of the first spiral heating tube, so that the high-temperature medium inside the first spiral heating tube insulates the high-temperature steam.

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0045] The embodiments of the present application provide a deodorizing device for cottonseed oil production and a method thereof, which solve the problem of condensate water on the pipe wall of the air inlet 102, which affects the quality of cottonseed oil when falling down. The aeration pipe 3 is generally installed at the bottom of the tank, which is prone to local aeration, resulting in general aeration effect. The spiral aeration pipe 3 cooperates with the plurality of micro-porous aeration heads 301 to perform range aeration of high-temperature steam in the processing tank 1, thereby increasing the aeration effect of the high-temperature steam. The second spiral heating pipe 202 can heat the pipe wall of the air inlet 102, so that the pipe wall of the air inlet 102 is in a high-temperature state, and thus the gas cannot form condensate water at the pipe wall of the air inlet 102.

[0046] In order to better understand the above technical scheme, the above technical scheme will be described in detail below in combination with the drawings of the specification and specific embodiments.

[0047] The embodiments of the present application disclose a deodorizing device for cottonseed oil production and a method thereof.

[0048] According to the drawings Figure 1-9 As shown in the drawings, a deodorizing device for cottonseed oil production includes a processing tank 1, the top of the processing tank 1 is provided with an air extraction pipe 101, the top end of the air extraction pipe 101 is connected with an external air pump, the bottom end of the air extraction pipe 101 enters the inside of the processing tank 1 and is provided with an air inlet 102, the inside of the processing tank 1 is provided with a deodorizing mechanism and a stirring mechanism;

[0049] The deodorizing mechanism includes:

[0050] A heating pipe 2 is provided inside the processing tank 1, with both ends of the heating pipe 2 extending outward. A heating medium is provided inside the heating pipe 2, and the heating pipe 2 is used to heat the cottonseed oil inside the processing tank 1;

[0051] An aeration pipe 3 is provided inside the processing tank 1, with the end of the aeration pipe 3 extending outward. High-temperature steam is provided inside the aeration pipe 3, and a plurality of microporous aeration heads 301 are installed on the outside of the aeration pipe 3;

[0052] The outer side of the microporous aeration head 301 is provided with a large number of holes. When opened, the holes open to form microbubbles, and when closed, the holes automatically close to prevent cottonseed oil from entering the microporous aeration head 301. The microporous aeration head 301 is a mature existing structure, so it will not be described in detail here.

[0053] The heating pipe 2 includes a first spiral heating pipe 201, a second spiral heating pipe 202, and a connecting pipe 203. The bottom and top ends of the connecting pipe 203 are connected to the first spiral heating pipe 201 and the second spiral heating pipe 202, respectively. The first spiral heating pipe 201 is located outside the stirring mechanism, and the aeration pipe 3 is spirally installed on the outer peripheral wall of the first spiral heating pipe 201. The second spiral heating pipe 202 is spirally installed on the outside of the air inlet 102.

[0054] Cottonseed oil is injected into the interior of the processing tank 1 through the feed pipe 103, and then the heated high-temperature medium is injected into the interior of the first spiral heating tube 201 through the liquid inlet pipe 204. After the tube wall of the first spiral heating tube 201 is heated by the high-temperature medium, the spiral state of the first spiral heating tube 201 quickly heats the cottonseed oil inside the processing tank 1.

[0055] The spiral aeration pipe 3 cooperates with a plurality of microporous aeration heads 301 to perform range aeration of the interior of the processing tank 1 with high-temperature steam, and the second spiral heating pipe 202 is used to heat the air inlet 102 .

[0056] High-temperature steam is pumped into the interior of the aeration pipe 3 by using the air inlet pipe 302. Since the aeration pipe 3 is spirally installed on the outer wall of the first spiral heating pipe 201, the spiral aeration pipe 3 cooperates with multiple microporous aeration heads 301 to perform range aeration of the high-temperature steam inside the processing tank 1, thereby increasing the aeration effect of the high-temperature steam. The high-temperature medium inside the first spiral heating pipe 201 enters the second spiral heating pipe 202 through the connecting pipe 203, and the second spiral heating pipe 202 is spirally installed on the outside of the air inlet 102, so that the second spiral heating pipe 202 can heat the pipe wall of the air inlet 102, so that the pipe wall of the air inlet 102 is at a higher temperature, thereby preventing the gas from forming condensed water at the pipe wall of the air inlet 102.

[0057] Furthermore, the bottom end of the second spiral heating tube 202 extends outward and is fixedly installed with a liquid inlet pipe 204, the bottom end of the aeration tube 3 extends outward and is fixedly connected with an air inlet pipe 302, and the top end of the second spiral heating tube 202 extends outward and is fixedly installed with a liquid outlet pipe 205.

[0058] Furthermore, a thermal insulation jacket 304 is installed on the outer sides of a portion of the liquid inlet pipe 204 and a portion of the air inlet pipe 302 . The thermal insulation jacket 304 is used to insulate the steam inside the air inlet pipe 302 .

[0059] A heat-insulating jacket 304 is installed outside a portion of the liquid inlet pipe 204 and a portion of the air inlet pipe 302. The heat-insulating jacket 304 keeps the steam inside the air inlet pipe 302 warm.

[0060] Furthermore, a lumen 2011 is defined inside the first spiral heating tube 201 , a special-shaped lumen 303 is defined inside the aeration tube 3 , a through hole 3031 is defined outside the aeration tube 3 , and the special-shaped lumen 303 is connected to the microporous aeration head 301 through the through hole 3031 .

[0061] When the high-temperature steam flows in the aeration tube 3 , the special-shaped tube cavity 303 is used to increase the contact area between the high-temperature steam and the tube wall of the first spiral heating tube 201 , so that the high-temperature medium inside the first spiral heating tube 201 can keep the high-temperature steam warm.

[0062] Specifically disclosed, a feed pipe 103 is installed on the outer side of the top of the processing tank 1 , and a discharge port 104 is installed on the bottom of the processing tank 1 .

[0063] After the deodorization of the cottonseed oil is completed, the cottonseed oil is discharged outwards through the discharge port 104.

[0064] It is particularly disclosed that the end of the feed pipe 103 extends toward the interior of the processing tank 1, the end of the feed pipe 103 is above the first spiral heating tube 201 and below the exhaust pipe 101, and the ends of the feed pipe 103 and the discharge port 104 facing the outside are both equipped with flanges.

[0065] Because the end of the feed pipe 103 is above the first spiral heating pipe 201, the cottonseed oil entering the processing tank 1 from the feed pipe 103 can cover the first spiral heating pipe 201. At the same time, the end of the feed pipe 103 is below the exhaust pipe 101, which prevents the cottonseed oil from contacting the exhaust pipe 101. Flanges are installed at the ends of the feed pipe 103 and the discharge port 104 that are exposed to the outside world, making it convenient to connect the pipelines outside the feed pipe 103 and the discharge port 104.

[0066] Specifically disclosed, the stirring mechanism includes a drive motor 4, which is fixedly installed at the bottom of the processing tank 1, and a stirring rod 401 is installed at the driving end of the drive motor 4, the top of the stirring rod 401 extends toward the interior of the processing tank 1, and a plurality of stirring blades are installed on the outside of the stirring rod 401.

[0067] By using the stirring mechanism, the drive motor 4 is turned on, and the driving end of the drive motor 4 drives the stirring rod 401 to rotate, thereby causing the multiple stirring blades on the outside of the stirring rod 401 to rotate, thereby stirring the high-temperature cottonseed oil inside, accelerating the aeration and deodorization speed of the cottonseed oil.

[0068] It is particularly disclosed that a reciprocating screw 5 is installed on the top of the stirring rod 401, and the outer side of the reciprocating screw 5 is threadedly connected to a nut seat 501, and the outer side of the nut seat 501 is fixedly sleeved with a fixed sleeve 502, and the top of the fixed sleeve 502 is provided with a lifting rod 503, and the top of the lifting rod 503 extends toward the inside of the air inlet 102 and is fixedly connected to a collecting ring 504, and a collecting groove is provided above the collecting ring 504, and a movable sleeve 505 is fixedly installed above the collecting ring 504, and the top of the movable sleeve 505 extends toward the inside of the exhaust pipe 101, and the movable sleeve 505 fits against the inner walls of the exhaust pipe 101 and the air inlet 102.

[0069] When the stirring rod 401 rotates, it drives the reciprocating screw 5 at its top to rotate accordingly, and then drives the fixed sleeve 502 and the lifting rod 503 to perform vertical reciprocating motion through the nut seat 501, so that the collecting ring 504 and the movable sleeve 505 are respectively moved vertically at the air inlet 102 and the exhaust pipe 101. When the movable sleeve 505 moves, the condensed water generated on the inner wall of the exhaust pipe 101 and the condensed water on the inner wall of the movable sleeve 505 itself are pushed down, so that the condensed water falls into the collecting ring 504 for collection.

[0070] Furthermore, a guide rail 506 is fixedly installed on the inner wall of the air inlet 102, and a guide rod 507 is fixedly installed on the outer side of the lifting rod 503. The end of the guide rod 507 is slidably connected to the inner wall of the guide rail 506, and a plurality of connecting strips 508 are fixedly connected between the top of the lifting rod 503 and the inner ring surface of the collecting ring 504.

[0071] The guide rail 506 and the guide rod 507 are provided to guide the lifting rod 503 so that the lifting rod 503 can only move vertically and cannot rotate. The top of the lifting rod 503 is connected to the collection ring 504 through the multiple connecting strips 508 provided thereon, and the air inlet 102 will not be blocked.

[0072] A method for a deodorizing device for cottonseed oil production comprises the following steps:

[0073] Step 1: First, cottonseed oil is injected into the interior of the processing tank 1 through the feed pipe 103, and then heated high-temperature medium is injected into the interior of the first spiral heating tube 201 through the liquid inlet pipe 204. After the high-temperature medium heats the tube wall of the first spiral heating tube 201, the spiral state of the first spiral heating tube 201 quickly heats the cottonseed oil inside the processing tank 1;

[0074] Step 2: After the cottonseed oil inside the processing tank 1 is heated, high-temperature steam is pumped into the interior of the aeration pipe 3 through the air inlet pipe 302. At the same time, a thermal insulation jacket 304 is installed on the outer side of a portion of the liquid inlet pipe 204 and a portion of the air inlet pipe 302. The thermal insulation jacket 304 insulates the steam inside the air inlet pipe 302. The high-temperature steam is injected into the cottonseed oil through a plurality of microporous aeration heads 301 on the outer peripheral wall of the aeration pipe 3. At the same time, because the aeration pipe 3 is spirally installed on the outer peripheral wall of the first spiral heating pipe 201, the spiral aeration pipe 3 cooperates with the plurality of microporous aeration heads 301 to perform aeration of the high-temperature steam in a wide range inside the processing tank 1, thereby increasing the aeration effect of the high-temperature steam. At the same time, in the process of the high-temperature steam flowing in the aeration pipe 3, the special-shaped tube cavity 303 is used to increase the contact area between the high-temperature steam and the tube wall of the first spiral heating pipe 201, so that the high-temperature medium inside the first spiral heating pipe 201 insulates the high-temperature steam.

[0075] Step 3: Turn on the drive motor 4. The drive end of the drive motor 4 drives the stirring rod 401 to rotate, thereby causing the multiple stirring blades on the outer side of the stirring rod 401 to rotate, thereby stirring the high-temperature cottonseed oil inside, accelerating the aeration and deodorization of the cottonseed oil;

[0076] Step 4: Turn on the external air pump connected to the exhaust pipe 101, so that the excess gas inside the processing tank 1 enters the exhaust pipe 101 through the air inlet 102 and is moved out to the outside. At this time, the high-temperature medium inside the first spiral heating tube 201 enters the second spiral heating tube 202 through the connecting tube 203, and the second spiral heating tube 202 is spirally installed on the outside of the air inlet 102, so that the second spiral heating tube 202 can heat the tube wall of the air inlet 102, so that the tube wall of the air inlet 102 is at a relatively high temperature, thereby preventing the gas from forming condensed water on the tube wall of the air inlet 102;

[0077] Step 5. When the gas inside the air inlet 102 enters the interior of the exhaust pipe 101, there is a certain possibility that condensed water will form on the inner wall of the exhaust pipe 101. When the stirring rod 401 rotates, it drives the reciprocating screw 5 at its top to rotate accordingly, and then drives the fixed sleeve 502 and the lifting rod 503 to perform vertical reciprocating motion through the nut seat 501, so that the collecting ring 504 and the movable sleeve 505 are respectively moved vertically in the air inlet 102 and the exhaust pipe 101. When the movable sleeve 505 moves, it pushes the condensed water generated on the inner wall of the exhaust pipe 101 and the condensed water on the inner wall of the movable sleeve 505 itself to slide downward, so that the condensed water falls into the collecting ring 504 for collection;

[0078] Step 6: After the cottonseed oil is deodorized, the cottonseed oil is discharged outwards through the discharge port 104, and then the air extraction pipe 101 blows air into the air inlet 102 to blow out the condensed water in the collection ring 504 and dry it.

[0079] The high-temperature steam is pumped into the aeration pipe 3 by using the air inlet pipe 302. Since the aeration pipe 3 is spirally installed on the outer peripheral wall of the first spiral heating pipe 201, the spiral aeration pipe 3 cooperates with multiple microporous aeration heads 301 to perform range aeration on the high-temperature steam inside the processing tank 1, thereby increasing the aeration effect of the high-temperature steam. The high-temperature medium inside the first spiral heating pipe 201 enters the second spiral heating pipe 202 through the connecting pipe 203, and the second spiral heating pipe 202 is spirally installed on the outer side of the air inlet 102, so that the second spiral heating pipe 202 The tube wall of the air inlet 102 can be heated so that the tube wall of the air inlet 102 is in a state of higher temperature, thereby preventing condensed water from forming at the tube wall of the air inlet 102. At the same time, the stirring rod 401 is used to drive the reciprocating screw 5 to rotate, thereby causing the collecting ring 504 and the movable sleeve 505 to move vertically in the air inlet 102 and the exhaust pipe 101 respectively, pushing the condensed water generated on the inner wall of the exhaust pipe 101 and the condensed water on the inner wall of the movable sleeve 505 itself to slide downward, thereby causing the condensed water to fall into the collecting ring 504 for collection.
