Technical Field

[0001] This invention belongs to the field of rapeseed oil extraction technology, and specifically relates to a rapeseed oil extraction process. Background Technology

[0002] Rapeseed oil, also known as rapeseed oil or mustard oil, is the world's third largest vegetable oil (after soybean oil and palm oil) and one of China's traditional edible oils. Due to the strong adaptability and high yield of its raw material (rapeseed), and the fact that the oil is rich in unsaturated fatty acids, it is widely used in daily cooking and the food industry.

[0003] In the rapeseed oil extraction process, a press is required. The most common press is the vertical press. Existing vertical presses use a pressing barrel composed of multiple hoops and plates arranged around the inside of the hoops. However, when using such a pressing barrel, rapeseed can get stuck in the gaps between adjacent plates, making it difficult to clean and causing considerable trouble for the entire extraction process.

[0004] Therefore, it is necessary to invent a rapeseed oil extraction process to solve the above problems. Summary of the Invention

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] This invention provides a rapeseed oil extraction process, comprising the following steps: S1. Roasting seeds: Roasting rapeseed at a low temperature (temperature ≤120℃). S2. Pressing: The roasted rapeseed is put into a pressing device for pressing to obtain rapeseed oil; S3. Filter the obtained rapeseed oil through a filter screen to obtain rapeseed oil; The pressing equipment includes: frame 1, hydraulic equipment 2, pressing plate 3, and easy-to-clean pressing barrel; The frame 1 is the frame of a vertical press in the prior art, the hydraulic equipment 2 is the hydraulic equipment of a vertical press in the prior art, and the pressure plate 3 is the pressure plate of a vertical press in the prior art. The hydraulic device 2 is fixedly installed on the top of the frame 1, and the pressure plate 3 is fixedly installed on the bottom of the hydraulic rod of the hydraulic device 2. The easy-to-clean pressing barrel can work with the pressure plate 3 to press rapeseed and is easy to clean itself.

[0018] When in use, put the rapeseed into the easy-to-clean pressing barrel, and use the hydraulic device 2 to drive the pressing plate 3 to descend and press the rapeseed.

[0019] like Figures 1 to 6 As shown, the easy-to-clean pressing barrel includes: hoop 4, short plate 5, long plate 6, and ejector assembly; Hoops 4 are equidistant from top to bottom. Short plates 5 are equidistantly arranged inside hoops 4. Short plates 5 are fixedly connected to multiple hoops 4. Long plates 6 are equidistantly arranged inside hoops 4. Long plates 6 and short plates 5 are staggered. The ejection assembly can eject the long plates 6 so that they are misaligned with the short plates 5.

[0020] When it is necessary to clean the residue on the sides of the short plate 5 and the long plate 6, the long plate 6 is pushed out by the ejector assembly to create a misalignment with the short plate 5. At this time, both sides of the long plate 6 and both sides of the short plate 5 are exposed, and there is no situation where the sides of the short plate 5 and the long plate 6 block each other. This makes it easier to clean the residue on the sides of the short plate 5 and the long plate 6. In addition, some rapeseed may get stuck in the gap between the short plate 5 and the long plate 6 and be difficult to clean. By misaligning the short plate 5 and the long plate 6, this part of the rapeseed can also be easily cleaned.

[0021] like Figures 3 to 6 As shown, the ejector assembly includes: a connecting rod 7, a rectangular plate 8, a housing 9, a first spring 10, an ejector rod 22, and a pushing assembly; The connecting rod 7 is fixedly installed on the outside of the long plate 6, the rectangular plate 8 is fixedly installed on the end of the connecting rod 7 away from the long plate 6, the number of housings 9 corresponds to the long plate 6, the housings 9 are fixedly installed on the top of the uppermost hoop 4, the rectangular plate 8 is slidably disposed inside the housing 9, the first spring 10 is fixedly installed on the side of the rectangular plate 8 near the long plate 6, the other end of the first spring 10 is fixedly connected to the inner wall of the housing 9, the push rod 22 is fixedly installed on the side of the long plate 6 near the housing 9, and the pushing assembly can push the push rod 22.

[0022] By pushing the pusher component, the push rod 22 is pushed to move the long plate 6, the connecting rod 7, and the rectangular plate 8 within the housing 9. This causes the long plate 6 to move towards the center of the hoop 4. When the rectangular plate 8 moves, it compresses the first spring 10, causing it to deform. This allows the long plate 6 to eventually be misaligned with the short plate 5, exposing the sides of both the long plate 6 and the short plate 5.

[0023] like Figure 3 and Figure 4 As shown, the pushing component includes: a ring plate 11, a push block 12, an arc surface 13, and a rotating component; The ring plate 11 is rotatably mounted on the top of the uppermost hoop 4, and the push block 12 is equidistantly fixed around the ring plate 11 on the side near the long plate 6. The arc surface 13 is set on one side of the push block 12, and the rotating assembly can drive the ring plate 11 to rotate.

[0024] The rotating assembly drives the ring plate 11 to rotate in the forward direction, causing the push block 12 to move accordingly. The push block 12, in conjunction with the arc surface 13, presses the top rod 22, causing it to move along with the long plate 6 towards the center of the hoop 4. Conversely, when the rotating assembly drives the ring plate 11 to rotate in the reverse direction and reset, the push block 12 releases the pressure on the top rod 22.

[0025] like Figure 3 As shown, the rotating assembly includes: teeth 14, motor 15, gear 16, and carrier plate; The carrier plate is fixedly installed on the outside of the uppermost hoop 4, the motor 15 is fixedly installed on the carrier plate, the gear 16 is fixedly installed on the top of the output shaft of the motor 15, and the teeth 14 are equidistantly arranged on the outside of the ring plate 11, and the teeth 14 mesh with the gear 16.

[0026] The motor 15 is started to make its output shaft rotate, which in turn drives the gear 16 to rotate, and then drives the ring plate 11 to rotate in conjunction with the teeth 14, thereby driving the ring plate 11.

[0027] If the staff makes a mistake while cleaning the rapeseed, some rapeseed may move to the contact surface between the long plate 6 and the hoop 4. When the misaligned long plate 6 is reset, it will come into contact with the rapeseed, which will prevent the long plate 6 from fully contacting and resetting with the hoop 4. As a result, the long plate 6 and the short plate 5 will not be flush on the inside, which will affect the subsequent pressing operation of the pressing plate 3. Therefore, as Figures 5 to 6 As shown, a striking arm 17 is provided on the outside of the hoop 4. The striking arm 17 abuts against the outer side of the multiple hoops 4. A striking assembly for driving the striking arm 17 to strike the hoop 4 is provided on the outside of the hoop 4.

[0028] After the long plate 6 and short plate 5 are cleaned, the beater arm 17 is driven by the beater assembly to beat the hoop 4, causing the hoop 4 to vibrate and shake off the rapeseed on the contact surface between the hoop 4 and the long plate 6, so that the long plate 6 can be completely reset and contacted with the hoop 4, thus avoiding the above-mentioned problems.

[0029] like Figure 5 and Figure 6 As shown, the striking assembly includes: a slide bar 18, a limiting block 19, a second spring 20, and an electromagnet 21; The slide rods 18 are fixedly installed on the outside of the uppermost and lowermost hoops 4 respectively. The limiting block 19 is fixedly installed on the end of the slide rod 18 away from the hoops 4. The racket rod 17 is slidably sleeved on the outside of the pair of slide rods 18. The second spring 20 is sleeved on the outside of the slide rod 18. The second spring 20 is located between the limiting block 19 and the racket rod 17. The electromagnet 21 is fixedly installed on the outside of the limiting block 19. The racket rod 17 is made of iron.

[0030] After the long plate 6 and short plate 5 are misaligned, and after cleaning the long plate 6 and short plate 5, the electromagnet 21 is energized to make it magnetic, causing the attracting lever 17 to move along the slide bar 18 towards the limiting block 19. The lever 17 compresses the second spring 20 to deform it. Then the electromagnet 21 is de-energized to make it lose its magnetism. Subsequently, the second spring 20 moves quickly with the lever 17 to reset, causing the lever 17 to strike the hoop 4, making the hoop 4 vibrate. Repeating the above operation can continuously strike the hoop 4 to make it vibrate.

[0031] The gap between the short board 5 and the long board 6 is sufficient for the long board 6 to move to a position offset from the short board 5.

[0032] Working principle: When in use, rapeseed is placed into the easy-to-clean pressing barrel, and the pressing plate 3 is driven down by the hydraulic device 2 to press the rapeseed. When it is necessary to clean the residue on the sides of the short plate 5 and the long plate 6, the motor 15 is started to rotate its output shaft, which in turn rotates the gear 16, which in turn drives the ring plate 11 to rotate in the forward direction in conjunction with the teeth 14, causing the push block 12 to move accordingly. The push block 12, in conjunction with the arc surface 13, presses the top rod 22, causing it to move the long plate 6, connecting rod 7, and rectangular plate 8 within the housing 9, so that the long plate 6 moves towards the center of the hoop 4. When the rectangular plate 8 moves, it compresses the first spring 10 to deform it, so that the long plate 6 can eventually be misaligned with the short plate 5, so that the sides of both the long plate 6 and the short plate 5 are exposed, and there is no situation where the sides of the short plate 5 and the long plate 6 block each other, making it easier to clean the residue on the sides of the short plate 5 and the long plate 6. In addition, some rapeseed may get stuck in the gap between the short plate 5 and the long plate 6 and be difficult to clean. By misaligning the short plate 5 and the long plate 6, this part of the rapeseed can also be easily cleaned. If the staff makes a mistake while cleaning the rapeseed, some rapeseed may move to the contact surface between the long plate 6 and the hoop 4. When the misaligned long plate 6 is reset, it will come into contact with the rapeseed, which will prevent the long plate 6 from fully contacting and resetting with the hoop 4. As a result, the long plate 6 and the short plate 5 will not be flush on the inside, which will affect the subsequent pressing operation of the pressing plate 3. Therefore, after the long plate 6 and short plate 5 are misaligned, and after cleaning the long plate 6 and short plate 5, the electromagnet 21 is energized to make it magnetic, causing the attracting lever 17 to move along the slide bar 18 towards the limiting block 19. The lever 17 compresses the second spring 20 to deform it. Then the electromagnet 21 is de-energized to make it lose its magnetism. Subsequently, the second spring 20 moves the lever 17 quickly back to its original position, causing the lever 17 to strike the hoop 4, causing the hoop 4 to vibrate. The above operation is repeated to continuously strike the hoop 4, causing it to vibrate and shake off the rapeseed on the contact surface between the hoop 4 and the long plate 6, so that the long plate 6 can be completely reset and contacted with the hoop 4, avoiding the above-mentioned problems.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
