Description

Technical Field

[0001] The invention relates to the technical field of duck oil processing, in particular to a duck oil heating extraction device and a liquid duck oil extraction method. Background Art

[0002] Most of the fat tissue of meat ducks is accompanied by protein and water, so oil extraction is required. The content of monounsaturated fatty acids and polyunsaturated fatty acids in duck oil is high and the ratio is balanced, which is close to the ideal value for maintaining human health. It is a good oil to be developed. Duck oil is a mixed system of various triglycerides. The difference in triglyceride types makes the oil have different melting point ranges, resulting in a turbid solid-liquid mixed state of duck oil at room temperature. This state is not conducive to the processing and utilization of duck oil in the food industry. Oil fractionation technology can separate the solid fat and liquid oil in the oil. Common fractionation methods include surfactant fractionation, solvent fractionation, liquid extraction fractionation and dry fractionation.

[0003] The Chinese patent with publication number CN212440334U discloses a duck oil filtering and stirring device, which includes a box body, legs are fixedly installed at the four corners of the bottom of the box body, a motor is fixedly installed on the top of the box body, the top of the first rotating shaft is fixedly connected to the output shaft of the motor, the bottom of the first rotating shaft extends into the box body, a plurality of stirring plates are fixedly installed on the outside of the first rotating shaft, a second rotating shaft is rotatably installed on one side of the box body, and a first pulley is fixedly installed on the outside of the first rotating shaft and the top of the second rotating shaft. The utility model has a reasonable structural design, can effectively improve the stirring and filtering effect of duck oil, and is convenient for the disassembly and installation of the fine filter, so as to facilitate the cleaning of the fine filter.

[0004] The Chinese patent with publication number CN1298408C discloses an apparatus and method for extracting oil with a solvent in an extraction chamber, the method comprising forming a solvent mist by effective adiabatic cooling, the pressure difference between the inlet and outlet of the extraction chamber driving the mist through the oil-containing material, the solvent being supplied to the extraction chamber at a pressure exceeding atmospheric pressure, and the outlet of the extraction chamber being subjected to a partial vacuum. Also included is a solvent extraction apparatus, comprising an extraction chamber for receiving the oil-containing material, the extraction chamber comprising a solvent spray injection system connected to a high-pressure solvent supply circuit portion through an inlet, the extraction chamber also connected to a low-pressure circuit portion through an outlet, and the low-pressure circuit portion is connected to a gas recovery vacuum pump system.

[0005] When the duck oil heating extraction device is in use, hot air heating is mostly used for heating. However, since the material needs to be stirred during heating in order to fully heat the material, as the duck oil gradually increases, the resistance of the stirring plate will gradually increase. When it reaches a certain threshold, it will become stuck or overloaded. At the same time, since the material contains a certain amount of moisture, water vapor is formed during the continuous heating process. If it is not handled in time, it will gather in the duck oil, thereby affecting the accuracy of the duck oil. Summary of the invention

Under the action of the air pressure difference, the hot air above can be collected to avoid the hot air from turning into water droplets after the temperature is lowered, thereby affecting the accuracy of the duck oil and requiring subsequent purification, which affects the overall processing. In order to improve efficiency, a first stirring component 4 is slidably connected to the middle of the outer surface of the rotating cylinder 2.

[0039] An air storage bin 12 is provided at the upper portion of the inner wall of the rotating cylinder 2. The outer surface of the air storage bin 12 is connected to four circumferentially arranged air intake pipes 13, and each air intake pipe 13 passes through the outer surface of the air collecting component 3. The bottom surface of the air storage bin 12 is connected to an exhaust pipe 14, and the lower end of the exhaust pipe 14 passes through the bottom surface of the heating tank 1. When the air intake pipe 13 is completely opened, the hot air can be quickly discharged through the exhaust pipe 14.

[0040] The first stirring assembly 4 includes a moving ring 401, which is made of metal material so that it can move with the magnet ring 8 under the magnetic force of the magnet ring 8. The outer surface of the moving ring 401 is provided with four first stirring plates 402 arranged in a circle, and the first stirring plate 402 is provided with a first slide groove 403 inside. The first slide groove 403 is slidably connected to the first control plate 404 inside. The left side of the first control plate 404 is provided with a scraper 405. When the scraper 405 is extended, it can contact the inner wall of the heating tank 1. Under the action of continuous rotation, the duck fat adsorbed on the inner wall can be scraped off to avoid omission. The right side of the first control plate 404 is provided with an extrusion block 406, and the extrusion block 4 06 has an inclined surface on its upper and lower surfaces, two symmetrical springs are arranged between the extrusion block 406 and the first slide groove 403, a through groove 407 is provided on the upper surface of the first control plate 404, a second control plate 408 is inserted into the upper surface of the first stirring plate 402, and the second control plate 408 passes through the through groove 407, a first magnet 409 is provided on the upper and lower surfaces of the second control plate 408, an extrusion plate 410 is provided on the upper surface of the first magnet 409 located at the lower part, and the upper surface of the extrusion plate 410 is in an arc shape, under the interaction between the first magnet 409 and the third magnet 706, the extrusion plate 410 can be made to rise, and under the action of the inclined surface, the extrusion block 406 can be moved to shrink the scraper 405.

[0041] The second stirring assembly 7 includes a second stirring plate 701, and the outer surface of the second stirring plate 701 is provided with two first oil outlets 702 arranged at equal distances, and the bottom surface of each first oil outlet 702 is an inclined surface, under the action of the inclined surface, the material below can be transported to the upper side, so that the material is mixed more evenly and heated more thoroughly, the upper surface of the second stirring plate 701 is provided with a second slide groove 703, the interior of the second slide groove 703 is slidably connected with a baffle 704, the bottom surface of the baffle 704 and the second slide groove 703 are provided with two symmetrical springs, and the outer surface of the baffle 704 is provided with two second oil outlets arranged at equal distances. Opening 705, and each second oil outlet 705 is adapted to the first oil outlet 702. By staggering the first oil outlet 702 and the second oil outlet 705, corresponding adjustments can be made according to the value detected by the torque sensor. The greater the torque, the larger the opening is to avoid jamming due to excessive resistance. A third magnet 706 is provided on the upper surface of the baffle 704, and the third magnet 706 and the first magnet 409 located at the bottom are magnetically repelled. When the third magnet 706 and the second magnet 306 are close to each other, magnetic repulsion can be generated, so that the baffle 704 is inserted into the second slide groove 703, so that it can push all materials to move.

[0042] Four positioning cylinders 5 arranged in a circle are provided at the lower part of the outer surface of the rotating cylinder 2. A positioning shaft 6 is slidably connected to the interior of each positioning cylinder 5. The positioning shaft 6 can rotate with the second stirring component 7. The second stirring component 7 is provided at one end of the positioning shaft 6 away from the rotating cylinder 2. A torque sensor is provided at the other end of the positioning shaft 6. The torque sensor can detect the resistance encountered by the second stirring component 7. The greater the resistance, the more duck oil is produced at this time. Correspondingly, the temperature rises and the water vapor is more. Therefore, corresponding adjustments are made according to the resistance encountered at this time to avoid jamming and the like. A torsion spring is provided between the positioning shaft 6 and the positioning cylinder 5. When the resistance reaches the threshold of the torsion spring, the torsion spring can be deformed. When the resistance becomes smaller, the second stirring plate 701 can be restored to its original position under the action of the torsion spring.

[0043] A magnet ring 8 is slidably connected to the inside of the rotating cylinder 2. The magnet ring 8 has a strong magnetic force and can attract objects made of iron, thereby causing the objects to move. A fan 9 is provided at the lower end of the rotating cylinder 2. When the fan 9 is started, the heat generated by the heating ring 11 can be introduced into the inside of the rotating cylinder 2, thereby increasing the internal gas and increasing the air pressure to push the magnet ring 8 to move, thereby achieving the purpose of freely adjusting the position of the magnet ring 8. A cavity 10 is provided inside the heating tank 1, and the cavity 10 is connected to the lower end of the rotating cylinder 2. A heating ring 11 is provided inside the cavity 10. When the heating ring 11 is energized, it can generate heat energy, thereby heating the gas inside the cavity 10, and heating the internal material by the high-temperature gas to avoid local overheating.

[0044] Two symmetrical feed ports 15 are provided on the upper surface of the heating tank 1, and a cover plate 16 is provided inside each feed port 15. An oil outlet pipe 17 is provided on the bottom surface of the heating tank 1, and a stop valve is provided at the lower end of the oil outlet pipe 17. A mounting cylinder 18 is provided in the middle of the upper surface of the heating tank 1, and a rotating shaft 19 is rotatably connected inside the mounting cylinder 18. The lower end of the rotating shaft 19 is fixedly connected to the upper surface of the rotating cylinder 2, and a first bevel gear 22 is provided at the upper end of the rotating shaft 19. A motor 20 is provided on the left side of the mounting cylinder 18, and a second bevel gear 21 is fixedly connected to the output shaft of the motor 20, and the second bevel gear 21 is meshed with the first bevel gear 22.

[0045] In actual use, first close the stop valve of the oil outlet pipe 17, then open the two cover plates 16, put the block material into the heating tank 1, and close the cover plate 16 again. Secondly, start the heating ring 11 to increase the temperature inside the cavity 10, thereby heating the internal material to make it fat. Then start the motor 20 to drive the second bevel gear 21 to rotate under the action of the output shaft, and drive the first bevel gear 22 to rotate under the action of meshing, and then drive the rotating shaft 19 and the rotating cylinder 2 to rotate in turn. Under the action of the rotating cylinder 2, the air storage box 301, the first stirring plate 402 and the second stirring plate 701 are driven to rotate respectively.

[0046] When the first stirring plate 402 and the second stirring plate 701 rotate, they can drive the material below to rotate, so that the material can continuously move inside the heating tank 1, so that the material is heated more evenly and the material keeps moving to avoid overheating. When the air storage box 301 rotates, the hot air above the heating tank 1 can be introduced into the air storage box 301 through the air inlet cylinder 303, so that the gas inside the air storage box 301 increases, causing the two air storage bags 302 to expand to a certain extent.

[0047] When the value detected by the torque sensor reaches the first threshold and continues to rise, it indicates that the duck fat gradually increases, causing the resistance of the first stirring plate 402 to increase, and the following adjustments need to be made:

[0048] Start the fan 9. Under the action of wind force, the hot air in the cavity 10 is introduced into the rotating cylinder 2, so that the air pressure in the rotating cylinder 2 gradually increases. Under the action of air pressure, the magnet ring 8 is pushed up. Under the adsorption of magnetic force, the motion ring 401 drives the first stirring plate 402 to rise, so that the first magnet 409 gradually moves away from the third magnet 706, so that the magnetic repulsion between the two is reduced. Under the action of the spring, the baffle 704 gradually rises until the first oil outlet 702 and the second oil outlet 705 overlap to allow the duck oil to pass through, reducing the resistance of the second stirring plate 701 and avoiding jamming. At the same time, due to the reduction of magnetic repulsion, under the action of gravity, the second control plate 408 drives the extrusion plate 410 to gradually descend, releasing the constraint on the extrusion block 406. Under the action of elasticity, the extrusion block 406 pushes the first control plate 404 and the scraper 405 to extend outward in turn, so that the scraper 405 can heat the inner wall of the tank 1 and contact it. Under continuous rotation, the inner wall can be effectively cleaned.

[0049] When the value detected by the torque sensor rises again and reaches the second threshold, it indicates that the duck fat increases again, causing the resistance of the first stirring plate 402 to increase again. Correspondingly, the temperature inside the heating tank 1 reaches the highest, causing the hot air collected above the heating tank 1 to continue to increase, and the following adjustments are required:

[0050] The fan 9 is started again. Under the action of wind force, the hot air in the cavity 10 is introduced into the rotating cylinder 2 again, so that the air pressure in the rotating cylinder 2 increases again. Under the action of air pressure, the magnet ring 8 is pushed up again. Under the adsorption of magnetic force, the motion ring 401 drives the first stirring plate 402 to rise again, so that the first magnet 409 is completely away from the third magnet 706, so that the magnetic repulsion between the two is reduced again until it disappears, and a magnetic repulsion is generated between the second magnet 306 above. Under the action of magnetic repulsion, the air blocking strip 304 gradually rises, and the vent 305 and the air inlet pipe 13 gradually overlap, so that the exhaust volume gradually increases. At the same time, since the air inlet pipe 13 is opened , so that the hot air can circulate, the air pressure inside the air storage bin 12 is reduced, the air storage bag 302 is deformed and contracted, and the gas inside the air storage box 301 is compressed again, so that it can enter the air storage bin 12 more quickly, and then the hot air is completely discharged through the exhaust pipe 14 to avoid excessive hot air from being discharged in time, thereby causing water mist and affecting the accuracy of the duck oil. Subsequently, the baffle 704 is raised again under the action of the spring until the first oil outlet 702 and the second oil outlet 705 are completely overlapped, so that the amount of duck oil passing through is modulated to the maximum, and the resistance of the second stirring plate 701 is reduced again to avoid the duck oil from increasing again, causing the second stirring plate 701 to get stuck.

[0051] Second embodiment

[0052] The present invention also provides a method for extracting liquid duck oil using a duck oil heating extraction device, and the specific operation steps are as follows:

[0053] S1. First, close the stop valve of the oil outlet pipe 17, then open the two cover plates 16, put the block material into the heating tank 1, and close the cover plates 16 again.

[0054] S2. Secondly, the heating ring 11 is started to increase the temperature inside the cavity 10, thereby heating the internal material to produce duck oil, and then the motor 20 is started to rotate the first stirring component 4 and the second stirring component 7 to accelerate the oil extraction efficiency of the material.

[0055] S3. Then, the resistance of the second stirring component 7 is detected through the torque sensor. The greater the resistance, the more duck oil is produced at this time. Correspondingly, the temperature rises and the water vapor is more. The wind force generated by the fan 9 makes the first oil outlet 702 and the second oil outlet 705 gradually contact, so that the oil output rate gradually increases, avoiding the jamming of the duck oil when excessive stirring occurs.

[0056] S4. Finally, the wind force generated by the fan 9 again increases the air volume of the air collecting component 3 to avoid affecting the air collecting efficiency. At the same time, the air collecting component 3 is connected to the outside world, and the hot air is discharged in sequence in a circulating manner to avoid excessive hot air and the formation of water mist, which affects the accuracy of the duck oil.

[0057] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
