Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sesame oil production and processing equipment, and in particular to a sesame screening device for sesame oil production. Background Technology
[0002] Sesame oil is extracted from sesame seeds and has a distinctive aroma, hence it is also known as fragrant oil. Based on the extraction method, it is generally divided into pressing, filtration, and water extraction. Small-batch sesame oil is made using the traditional water extraction method.
[0003] During sesame oil processing, the sesame seeds need to be screened. Sesame seeds contain impurities such as sesame husks and stones, which need to be removed. Currently used screening devices mostly employ multi-stage screens, resulting in poor screening efficiency. Furthermore, stones and other impurities accumulate on the screens, making cleaning difficult and impacting screening efficiency. Summary of the Invention
[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a sesame screening device for sesame oil production that can separate impurities, facilitates cleaning of the filter screen, and is easy to use.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A sesame screening device for sesame oil production includes a screening box, and a support leg is fixedly installed at the lower end of the screening box.
[0007] A feed inlet is fixedly installed at the upper end of the screening box. A guide cylinder is fixedly installed inside the screening box. The upper end of the guide cylinder is connected to the feed inlet, and the lower end of the guide cylinder is set downward. An air duct is fixedly installed on one side of the screening box. One end of the air duct passes through the screening box and has an air outlet. The other end of the air duct is located inside the screening box and has a fan fixedly installed thereon. A slag pan is fixedly installed on the other side of the screening box. The upper end of the slag pan is open. The slag pan is inclined. The lower end of the slag pan passes through the screening box and extends outward. The fan is spaced apart from the slag pan.
[0008] The screening box is equipped with a sieve plate with sieve holes. One end of the sieve plate is rotatably connected to the screening box. The screening box has an opening and closing port. The other end of the sieve plate passes through the opening and closing port and extends outward. A position locking structure is installed between the screening box and the sieve plate.
[0009] The screening box has a discharge port on one side of its lower end, and the discharge port has an opening facing downwards.
[0010] In this process, sesame raw materials are placed in the feed inlet, enter the guide cylinder through the inlet, and fall from the guide inlet. A blower agitates the sesame raw materials, causing the sesame husks to drift to one side and fall into the residue tray. The residue tray is tilted, with its lower end positioned outside the screening box, allowing the sesame husks to flow outwards to the outside of the screening box. Sesame seeds and gravel impurities fall onto the screen tray, pass through the screen holes into the screening box, and are discharged from the outlet. The gravel impurities remain on the screen tray. After a certain screening time, the position locking structure opens, the screen tray rotates downwards, causing the gravel impurities on the screen tray to flow downwards and out through the opening / closing port, thus cleaning the gravel impurities. After cleaning, the screen tray is rotated, and the position locking structure locks the position of the screen tray.
[0011] The position locking structure includes a locking block, which includes a locking rod and chucks fixedly installed at both ends of the locking rod. A connecting plate is fixedly installed on the screening box. The screening plate and the connecting plate have notches facing each other. The locking rod engages with the notches. The two chucks are located above the connecting plate and below the screening plate.
[0012] The lower end of the sieve disc is fixedly installed with an arc-shaped baffle, and the outer side of the screening box has an outer wall that fits against the arc-shaped baffle. The length of the arc-shaped baffle in the vertical direction is greater than the length of the opening and closing port in the vertical direction.
[0013] The bottom surface of the screening box is inclined towards the discharge port.
[0014] A filter screen is fixedly installed at the air outlet of the air duct.
[0015] A pneumatic vibrator is fixedly installed on the outside of the screening box.
[0016] The slag pan has an opening at its outer end.
[0017] In summary, this sesame screening device for sesame oil production has the advantages of separating impurities, facilitating filter cleaning, and being easy to use. Attached Figure Description

[0026] like Figure 1-7 As shown, a sesame screening device for sesame oil production includes a screening box 1, and a support leg 2 is fixedly installed at the lower end of the screening box.
[0027] A feed inlet 3 is fixedly installed at the upper end of the screening box. A guide cylinder 4 is fixedly installed inside the screening box. The upper end of the guide cylinder is connected to the feed inlet, and the lower end of the guide cylinder is set downward. An air duct 5 is fixedly installed on one side of the screening box. One end of the air duct passes through the screening box and has an air outlet. The other end of the air duct is located inside the screening box and has a blower 6 fixedly installed. A slag pan 7 is fixedly installed on the other side of the screening box. The upper end of the slag pan is open. The slag pan is inclined. The lower end of the slag pan passes through the screening box and extends outward. The blower and the slag pan are spaced apart.
[0028] The screening box is equipped with a sieve plate 8, which has sieve holes. One end of the sieve plate is rotatably connected to the screening box. The screening box has an opening and closing port. The other end of the sieve plate passes through the opening and closing port and extends outward. A position locking structure is installed between the screening box and the sieve plate.
[0029] The screening box has a discharge port 9 on one side of its lower end, and the discharge port has an opening facing downwards.
[0030] In this process, sesame raw materials are placed in the feed inlet, enter the guide cylinder through the inlet, and fall from the guide inlet. A blower agitates the sesame raw materials, causing the sesame husks to drift to one side and fall into the residue tray. The residue tray is tilted, with its lower end positioned outside the screening box, allowing the sesame husks to flow outwards to the outside of the screening box. Sesame seeds and gravel impurities fall onto the screen tray, pass through the screen holes into the screening box, and are discharged from the outlet. The gravel impurities remain on the screen tray. After a certain screening time, the position locking structure opens, the screen tray rotates downwards, causing the gravel impurities on the screen tray to flow downwards and out through the opening / closing port, thus cleaning the gravel impurities. After cleaning, the screen tray is rotated, and the position locking structure locks the position of the screen tray.
[0031] The fan separates sesame seeds from their husks, while the sieve disc separates them from gravel and other impurities. The sieve disc can also rotate for easy cleaning. The sides of the sieve disc slide against the inner wall of the screening box, preventing stone particles from falling between the disc and the box's side walls.
[0032] In implementation, the position locking structure includes a locking block 10, which includes a locking rod 11 and chucks 12 fixedly installed at both ends of the locking rod. A connecting plate 13 is fixedly installed on the screening box. The screening plate and the connecting plate have notches facing each other. The locking rod engages with the notches, and the two chucks are located above the connecting plate and below the screening plate. The locking block secures the position of the connecting plate and the screening plate, facilitating use. When cleaning the screening plate is required, the locking block is removed, allowing the screening plate to rotate.
[0033] In implementation, an arc-shaped baffle 14 is fixedly installed at the lower end of the sieve disc. The outer side of the screening box has an outer wall that fits against the arc-shaped baffle, and the vertical length of the arc-shaped baffle is greater than the vertical length of the opening and closing port. Through the setting of the arc-shaped baffle, during the sesame screening process, the arc-shaped baffle blocks the opening and closing port. When cleaning the sieve disc, the arc-shaped baffle can slide and fit against the outer side of the screening box, resulting in high stability.
[0034] In practice, the bottom surface of the screening box is tilted towards the discharge port. This facilitates the movement of sesame seeds towards the discharge port for rapid discharge.
[0035] During implementation, a filter screen 15 is fixedly installed at the air outlet of the air duct to facilitate the filtration of the air entering the screening box.
[0036] In practice, a pneumatic vibrator is fixedly installed on the outside of the screening box. This provides vibration, allowing the screening disc to better separate the sesame seeds.
[0037] In practice, the outer end of the slag tray is open to facilitate the falling of sesame seed shells.
[0038] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
