[0003] When producing vegetable oil, if the raw materials contain too much water, the oil yield of the raw materials will be low and the oil will contain a lot of water, which will seriously affect the quality of the oil. Therefore, before producing vegetable oil, the raw materials need to be fried dry to reduce the water content of the raw materials and improve the oil yield and quality of the raw materials.

[0036] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0037] See also Figures 1 to 12. It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0038] like Figure 1-Figure 3 As shown, the present invention provides a raw material frying and drying device for vegetable oil production, comprising a supporting mechanism 1, a transmission mechanism 2, a stir-frying mechanism 3, a heating mechanism 4 and a sealing mechanism 5. The supporting mechanism 1 is used to support the entire device. The stir-frying mechanism 3 is arranged inside the supporting mechanism 1, and the inside of the stir-frying mechanism 3 can store raw materials for preparing vegetable oil. The transmission mechanism 2 is used to drive the stir-frying mechanism 3, which can rotate the stir-frying mechanism 3, so that the raw materials in the stir-frying mechanism 3 are turned with the rotation of the stir-frying mechanism 3, thereby realizing the stir-frying of the raw materials. At the same time, the hot air input from the outside can be transported to the inside of the stir-frying mechanism 3 through the transmission mechanism 2 to dry the raw materials in the stir-frying mechanism 3. The hot air blown at a high speed can blow the raw materials away to avoid the raw materials from piling up together, and cooperate with the rotating force of the stir-frying mechanism 3 to make the raw materials evenly stir-fried and dried, thereby improving the efficiency of frying the raw materials. The heating mechanism 4 is arranged outside the supporting mechanism 1. The heating mechanism 4 heats the air electrically and blows the hot air to generate a high-temperature, high-speed airflow. The high-speed airflow blows toward the raw materials inside the stir-frying mechanism 3 through the internal channel of the transmission mechanism 2, and takes away the moisture in the raw materials through the heat. The sealing mechanism 5 is arranged at the end of the supporting mechanism 1 in an openable and closable manner. The sealing mechanism 5 can block the mouth of the stir-frying mechanism 3 to prevent the leakage of the raw materials and allow moisture to be discharged.

[0039] like Figure 1-Figure 3 and Figure 5 As shown, in some embodiments, the support mechanism 1 of the present invention includes a support base 101, which is used to support and balance the entire device to ensure the stability of the device during operation. A limiting cylinder 102 is provided on the top of the support base 101, and the interior of the limiting cylinder 102 is used to limit the stir-fry mechanism 3. One end of the limiting cylinder 102 is open, which can facilitate the addition and removal of raw materials into the stir-fry mechanism 3. A motor bracket 103 is provided at one end of the support base 101 away from the opening of the limiting cylinder 102.

[0040] like Figure 2-Figure 6As shown, in some embodiments, the transmission mechanism 2 of the present invention includes a transmission motor 201, and the transmission motor 201 is installed on the top of the motor bracket 103. A hollow drive shaft 202 is provided at the output end of the transmission motor 201. When the transmission motor 201 is working, a torque is generated, and the torque can drive the drive shaft 202. The drive shaft 202 passes through the axis of the limiting cylinder 102 and extends to the inside of the limiting cylinder 102.

[0041] The outer surface of the driving shaft 202 is provided with a connection groove 203, and the connection groove 203 is provided with a ventilation groove 204, and the ventilation groove 204 is hollow and connected with the inside of the driving shaft 202. The high-temperature gas enters the inside of the driving shaft 202 through the ventilation groove 204, and enters the inside of the stir-frying mechanism 3 through the hollow channel inside the driving shaft 202, thereby drying the raw materials when the stir-frying mechanism 3 stirs the raw materials.

[0042] The outer surface of the connecting groove 203 is sleeved with a connecting sleeve 205, and the connecting sleeve 205 is used to seal the ventilation groove 204. The outer surface of the connecting sleeve 205 is provided with an intake pipe 206 that penetrates the interior of the connecting sleeve 205. When the high-temperature gas is transmitted through the intake pipe 206, it can enter the interior of the drive shaft 202 through the connecting sleeve 205 and the ventilation groove 204 respectively. And when the drive shaft 202 rotates, the intake pipe 206 can also stably supply gas to the interior of the drive shaft 202.

[0043] The end of the driving shaft 202 is sleeved with a gas delivery component 207 and fixed by bolts. When maintaining, the gas delivery component 207 can be removed by removing the bolts, which improves the convenience of maintenance. The gas delivery component 207 is surrounded by equidistant air outlets. The gas passing through the inside of the driving shaft 202 is finally blown out from the air outlets on the gas delivery component 207 to the inside of the stir-frying mechanism 3. And the gas is blown to the raw materials in a large direction through the air outlets surrounding the gas delivery component 207. The raw materials float inside the stir-frying mechanism 3 under the pressure of the air flow, and the high-speed air flow can blow away the accumulated raw materials, improving the uniformity of the heating of the raw materials. At the same time, the high-temperature air flow heating method is not easy to burn the raw materials compared to the direct heating method.

[0044] like Figure 7As shown, in some embodiments, the gas delivery component 207 of the present invention includes a gas delivery pipe 2071, and a horizontally movable air pressure valve core 2072 is disposed inside the gas delivery pipe 2071. A cavity is disposed inside the air pressure valve core 2072, and an end of the air pressure valve core 2072 facing the drive shaft 202 is an open port. After the hot air flow enters the gas delivery pipe 2071 from the mouth of the gas delivery pipe 2071, the air pressure valve core 2072 will be displaced horizontally inside the gas delivery pipe 2071 under the pressure of the air flow. A limit ring 2073 is provided on the inner wall of the gas pipe 2071 to limit the open end of the air pressure valve core 2072. The limit ring 2073 is used to prevent the air pressure valve core 2072 from being separated from the inside of the gas pipe 2071. In order to further improve the stability of the movement of the air pressure valve core 2072, a sliding bar can be provided on the outer surface of the air pressure valve core 2072, and a sliding groove can be provided on the inner wall of the gas pipe 2071. The sliding bar and the sliding groove cooperate to prevent the air pressure valve core 2072 from rotating. A spring member 2074 is also provided inside the gas pipe 2071 to support the closed end of the air pressure valve core 2072. When the air pressure valve core 2072 is not subjected to air flow pressure, the spring member 2074 will exert a reaction force on the air pressure valve core 2072, thereby pushing the air pressure valve core 2072 back to the initial state. The air pressure valve core 2072 is provided with an air hole that matches the air outlet hole on the air supply pipe 2071. When the spring member 2074 is naturally flexed, the air hole on the air pressure valve core 2072 is offset and sealed from the air outlet hole on the air supply pipe 2071. The air pressure valve core 2072 can compress the spring member 2074 after being subjected to gas pressure to connect the air outlet hole and the air hole. When the raw materials are fried, the high hot air flow will push the air pressure valve core 2072 to move horizontally, so that the air hole and the air outlet hole are connected, and high-temperature gas is supplied to the inside of the stir-frying mechanism 3. When the gas is not supplied, the spring member 2074 will drive the spring member 2074 back to the initial position to displace the air outlet hole and the air hole, so that the air outlet hole is closed to prevent the raw materials or debris from blocking the air outlet.

[0045] like Figure 1-Figure 3 and Figure 5As shown, in some embodiments, the stir-fry mechanism 3 of the present invention includes a stir-fry drum 301. When the raw materials are stir-fried, the raw materials are placed in batches inside the stir-fry drum 301. The stir-fry drum 301 is coaxially arranged on the outer surface of the gas delivery component 207 with the gas delivery component 207. When the transmission motor 201 drives the gas delivery component 207 to rotate, the rotating gas delivery component 207 will drive the stir-fry drum 301 to rotate, so that the raw materials inside the stir-fry drum 301 are turned over to achieve the effect of stir-frying. The inner wall of the stir-fry drum 301 is provided with stirring blades 302. When the stir-fry drum 301 rotates, the stirring blades 302 arranged inside the stir-fry drum 301 will increase the turning amplitude of the raw materials, thereby improving the effect of stir-frying the raw materials. And the stirring blades 302 can make the raw materials better thrown under the action of centrifugal force, and cooperate with the impact of high-speed airflow, which can improve the efficiency and uniformity of stir-frying.

[0046] like Figure 6 As shown, in some embodiments, a connection flange 208 is provided at the connection between the gas delivery component 207 and the drive shaft 202 of the present invention. The sealing end of the stir-fry drum 301 overlaps the connection flange 208, and the stir-fry drum 301 is fixed to the connection flange 208 by bolts. The stir-fry drum 301 is fixed by using bolts and the connection flange 208, so that the stir-fry drum 301 can be freely disassembled from the gas delivery component 207. It is convenient to maintain and clean the stir-fry drum 301 later.

[0047] like Figure 1-Figure 3 and Fig.11 As shown, in some embodiments, a processing groove 104 is provided in the middle of the limit cylinder 102 of the present invention, so that a part of the stir-frying drum 301 can be exposed. The outer surface of the stir-frying drum 301 located at the processing groove 104 is provided with circumferentially distributed mounting threaded holes 303, and a threshing rod 304 is installed in the mounting threaded hole 303 in a threaded manner. Many raw materials of vegetable oil need to be separated from the plant or sliced, such as peanuts, sesame, etc. When separating from the raw materials, a thresher-like device is generally used for separation. When the vegetable oil raw materials are fried dry, the stir-frying drum 301 will generate a rotating force. If it is combined with the threshing rod 304, a relatively simple thresher can be formed, so that the raw materials of the vegetable oil can be threshed. It can be realized that the vegetable oil raw materials can be processed while waiting for frying to dry, improve work efficiency, and reduce energy consumption.

[0048] The side of the support base 101 is provided with a discharge port 105 which is connected to the bottom of the processing tank 104. After the vegetable oil raw material is separated from the threshing rod 304, it will fall between the processing tank 104 and the stir-frying drum 301. At this time, the vegetable oil raw material will fall out through the discharge port 105 under the action of gravity, so as to facilitate collection.

[0049] like Fig.12As shown, in some embodiments, the outer surface of the stir-fry drum 301 of the present invention can be installed with a chipping blade 305 by installing a threaded hole 303 and a bolt. For the vegetable oil production raw materials that need to be sliced, the threshing rod 304 is disassembled and replaced with a chipping blade 305 with a blade. When slicing, the raw material is placed at the bottom of the opening of the processing groove 104 for support, and then a thrust is applied in the direction of the chipping blade 305, and the chipping blade 305 will slice the raw material under the power of the rotation of the stir-fry drum 301. The sliced ​​raw material will fall into the gap between the processing groove 104 and the stir-fry drum 301, and finally discharged from the discharge port 105 and collected.

[0050] like Figure 1 , Figure 8-Figure 9 As shown, in some embodiments, the heating mechanism 4 of the present invention includes a protection box 401, which is used to provide a relatively closed space to isolate the heat and reduce the possibility of external burns. Therefore, the protection box 401 is preferably made of heat-insulating and high-temperature resistant materials. An isolation plate 402 is provided inside the protection box 401 to divide the interior of the protection box 401 into two spaces. One of the spaces is used as an equipment installation cabin, and the other space is used as a heat source generation and airflow channel. Isolation by the isolation plate 402 can avoid mutual interference between the two spaces.

[0051] Specifically, a power controller 403 and an air supply device 404 are provided in a part of the space of the protection box 401, and both the power controller 403 and the air supply device 404 are connected to an external power source through wires. A heating unit 405 is provided in another part of the space. The power controller 403 is used to control the heating temperature of the heating unit 405 to heat the air. The air supply end of the air supply device 404 extends to the bottom of the heating unit 405, and is used to blow a high-speed airflow to the heating unit 405. The high-speed airflow is connected to the air inlet pipe 206 from the wall of the protection box 401 just above the heating unit 405. Thereby, the heated air can be transmitted to the inside of the stir-fry drum 301 through the air inlet pipe 206 to dry the raw materials.

[0052] It should be noted that the heating unit 405 includes: a support frame 4051. A plurality of horizontal heating tubes 4052 are arranged inside the support frame 4051. A beam frame 4053 is arranged between two adjacent horizontal heating tubes 4052, and a plurality of vertical heating tubes 4054 are evenly arranged on all beam frames 4053, and the lines of the vertical heating tubes 4054 are led out through the inside of the hollow beam frame 4053. The arrangement of the horizontal heating tubes 4052 and the vertical heating tubes 4054 can improve the efficiency of heating the air. At the same time, the high-speed airflow needs to pass between the horizontal heating tubes 4052 and the vertical heating tubes 4054. The vertically arranged vertical heating tubes 4054 can increase the time for the airflow to pass through the heating zone, and can transmit high-temperature air more stably.

[0053] All horizontal heating tubes 4052 and vertical heating tubes 4054 are individually controlled by the power controller 403. According to different vegetable oil raw materials and different frying and drying stages, the working quantity and working temperature of the horizontal heating tubes 4052 and vertical heating tubes 4054 are controlled respectively to improve the adaptability of the equipment and avoid the coking of the raw materials.

[0054] like Fig.10 As shown, in some embodiments, the sealing mechanism 5 of the present invention includes a sealing cover 501 for preventing the raw materials from falling from the mouth of the stir-frying drum 301 and the limiting cylinder 102 when the raw materials are stir-fried. The sealing cover 501 is hinged to the mouth of the limiting cylinder 102, so that the sealing cover 501 can be easily opened and closed, in order to ensure the stability of the opening and closing of the sealing cover 501. The hinge of the sealing cover 501 and the limiting cylinder 102 is connected by a damping shaft, and a buckle is provided to fix the sealing cover 501 after closing. A filter screen 502 is provided at the center of the sealing cover 501, and the filter screen 502 is used for ventilation and blocking the raw materials. In the process of frying the raw materials, the moisture with water is discharged, the drying speed of the raw materials is accelerated, and the excessive accumulation of heat is avoided to cause the raw materials to coke. A detachable flange ring 503 is provided on the side of the sealing cover 501 away from the limiting cylinder 102, and a recovery net 504 is provided inside the flange ring 503. The raw materials for vegetable oil production often contain debris such as shell fragments and fruit skins, which can affect the oil product when the vegetable oil is refined or pressed. At this time, the high-speed airflow drives these debris through the filter 502 and enters the inside of the recovery net 504 to be collected.

[0055] The specific use process of the present invention is as follows: Open the sealing cover 501 to expose the opening of the stir-fry drum 301, and fill the vegetable oil raw material into the stir-fry drum 301 through the opening of the stir-fry drum 301; Close the sealing cover 501, and start the transmission motor 201, the power controller 403 and the air supply device 404 respectively; The transmission motor 201 drives the stir-fry drum 301 to rotate and stir-fry the raw materials, and the power controller 403 energizes the heating part 405 so that the heating part 405 heats the air, and the high-speed airflow generated by the air supply device 404 drives the hot air to be transmitted from the air inlet pipe 206 to the inside of the stir-fry drum 301 to heat the raw materials; The high-speed hot air blows the raw materials in the stir-fry drum 301, so that the raw materials in the stir-fry drum 301 float under the action of the high-speed airflow, and the impurities pass through the filter net 502 and enter the interior of the recovery net 504 for separation and collection; After the raw materials for vegetable oil production are fried and dried, the transmission motor 201, the power controller 403 and the air supply device 404 are turned off respectively, and the sealing cover 501 is opened to take out the raw materials from the inside of the stir-frying drum 301 for use.

[0056] In summary, the device for frying and drying raw materials for vegetable oil production of the present invention places the raw materials for vegetable oil production inside the frying mechanism 3, and drives the frying mechanism 3 through the transmission mechanism 2, so that the frying mechanism 3 rotates to stir the raw materials. At the same time, the heating mechanism 4 inputs high-speed, high-temperature gas into the inside of the frying mechanism 3 through the transmission mechanism 2, and the raw materials in the frying mechanism 3 are heated by the high-temperature gas. The high-speed airflow causes the raw materials to float, further improving the uniformity of frying. The moisture generated during the frying process is discharged to the outside through the sealing mechanism 5, thereby achieving the effect of even frying and avoiding burning.

[0057] The present invention provides a plurality of air holes on the air pipe 2071, and sets an air pressure valve core 2072 inside the air pipe 2071. Meanwhile, an air outlet matched with the air holes is set on the air pressure valve core 2072, and the air pressure valve core 2072 is driven by a spring member 2074. In a natural state, the air holes are sealed by the air pressure valve core 2072 to prevent raw materials from entering the air pipe 2071 and causing blockage. In a ventilated state, the air pressure pushes the air pressure valve core 2072 to compress the spring member 2074, so that the air holes and the air outlet are interconnected to supply hot air to the inside of the stir-frying drum 301 to dry the raw materials. The air pipe 2071 rotates with the stir-frying drum 301, and the blown air flow also rotates accordingly, so that the tumbling raw materials are suspended, thereby achieving the effect of avoiding blockage of the air holes and further improving the frying efficiency.

[0058] The present invention hinges a sealing cover 501 at the end of a limiting cylinder 102, and sets a filter net 502 in the middle of the sealing cover 501 to block the raw materials. At the same time, a detachable flange ring 503 is installed inside the sealing cover 501 to support a recovery net 504. When frying the vegetable oil raw materials, high-speed airflow can be discharged through the recovery net 504, and the raw materials will be blocked by the filter net 502, while fine impurities or skins will pass through the filter net 502 and be collected inside the recovery net 504, thereby achieving the effect of separating impurities.

[0059] The present invention opens a processing groove 104 on the limiting cylinder 102, and correspondingly sets a mounting threaded hole 303 on the outer surface of the stir-frying drum 301, and installs a threshing rod 304 or a chipping blade 305 on the mounting threaded hole 303. While the vegetable oil raw material is being stir-fried, the vegetable oil raw material can be processed, such as threshing and slicing, thereby achieving the effect of saving energy and improving processing efficiency.

[0060] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0061] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
