Description

Technical Field

[0001] This invention relates to the field of pressing and processing technology, and more specifically, to a pressing and processing apparatus for sesame oil production. Background Technology

[0002] Sesame oil, as a high-quality edible oil, requires extremely high standards in its pressing process. Traditional sesame oil production often uses vertical hydraulic oil presses. While this equipment can preserve the flavor of the oil to some extent, it is an intermittent, batch-based production method. Each pressing requires tedious manual loading and unloading operations, which cannot meet the large-scale, assembly-line production needs of modern oil companies. Therefore, to achieve continuous, high-efficiency, and automated production, large-scale sesame oil processing enterprises have generally switched to horizontal single-shaft screw oil presses. In a horizontal screw oil press, the material continuously falls into the feed inlet and is continuously pushed towards the cake outlet by the high-speed rotation of the screw and the spiral guide, undergoing extremely strong radial compression, thereby achieving continuous oil-crust separation.

[0003] To extract every last drop of oil from the material, the front and middle sections of the screw in a horizontal screw oil press are covered with spiral blades to provide forward axial propulsion. At the very end of the screw (i.e., the cake discharge extreme pressure zone), it is usually designed as a "smooth cylinder" without any threads. During operation, this smooth cylinder forms an extremely narrow annular smooth gap with the inner wall of the extrusion cylinder. The material is subjected to the most extreme pure radial compression here, thereby achieving the highest oil yield.

[0004] However, the existing technology still has shortcomings. Under normal production conditions with continuous feeding, the residue in the extreme pressure zone of the cylinder must rely entirely on the continuous supply of new material from the threaded section behind as a "physical pusher" to be forcibly pushed out of the extrusion cylinder. When a single batch of production ends, the equipment stops feeding and is about to be shut down, the continuous thrust of the material behind disappears instantly. At this time, the residual sesame cake residue between the cylinder and the inner wall of the extrusion cylinder cannot be discharged from the outside of the equipment. Under the high temperature and residual heat and the closed environment, it is very easy to undergo severe oxidation and rancidity in a short period of time, and even breed deadly carcinogens such as aflatoxin, forming a serious food hygiene hazard. Summary of the Invention

[0005] The present invention provides a pressing and processing device for sesame oil production, which aims to solve the following problem: In existing pressing and processing devices for sesame oil production, under normal production conditions with continuous feeding, the residue in the extreme pressure zone of the cylinder must rely entirely on the continuous supply of new material from the rear threaded section as a "physical pusher" to be forcibly pushed out of the pressing cylinder. When a single batch of production ends, the equipment stops feeding and is about to be shut down, the continuous pushing force of the material from the rear disappears instantly. At this time, the residual sesame cake residue between the cylinder and the inner wall of the pressing cylinder cannot be discharged from the outside of the equipment. Under the high temperature and residual heat and in a closed environment, it is very easy to undergo severe oxidation and rancidity in a short period of time, and even breed deadly carcinogens such as aflatoxin, forming a serious food hygiene hazard.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pressing and processing device for sesame oil production, including a processing table, an oil pressing mechanism fixedly arranged on the processing table, the oil pressing mechanism including a pressing cylinder, the pressing cylinder fixedly arranged on the processing table, and an oil outlet cover and a feeding hopper arranged on the pressing cylinder; The pressing cylinder is equipped with a screw press, and a rotating telescopic mechanism is also installed on the processing table. The drive end of the rotating telescopic mechanism is fixedly installed with the end of the screw press. The raw material to be pressed enters the pressing cylinder through the feed hopper. The drive end of the rotating telescopic mechanism drives the screw press to rotate and press the raw material. The sesame oil formed by pressing is discharged through the oil outlet hood. The screw press is equipped with a slag cleaning unit. The slag cleaning unit adheres to the inner wall of the pressing cylinder by fitting against the inner wall of the screw press, so that the residue adhering to the inner wall of the pressing cylinder is peeled off the inner wall of the pressing cylinder. The drive end of the rotating telescopic mechanism drives the screw press to move along the length of the pressing cylinder, so that the residue in the pressing cylinder is discharged through its end.

[0007] In a preferred embodiment, the slag cleaning unit includes a slag cleaning mechanism, which includes an air-expanding ring. A groove is provided inside the screw press, and a through hole is provided on the inner wall of the groove. The air-expanding ring is located inside the through hole, and an air inlet pipe is fixedly connected to the air-expanding ring. A fixed seat is fixedly provided inside the groove, and the air-expanding ring is sleeved on the fixed seat.

[0008] In a preferred embodiment, the slag cleaning unit includes a second slag cleaning mechanism, which includes a second rotary driver. The second rotary driver is fixedly installed in the groove, and a threaded rod is fixedly installed on the output end of the second rotary driver. An adjusting seat is slidably installed in the groove, and the adjusting seat is threadedly connected to the threaded rod. A sliding groove is opened on the adjusting seat, and a scraper is slidably installed in the sliding groove. An elastic element is provided between the scraper and the inner wall of the sliding groove. The end of the screw press squeezes the scraper to make it slide in the sliding groove.

[0009] In a preferred embodiment, the end of the screw press is provided with a placement groove, a roller is rotatably arranged in the placement groove, and an inclined surface is provided on the scraper, with the roller rolling in relation to the inclined surface.

[0010] In a preferred embodiment, the adjusting seat is provided with a positioning mechanism, which includes a gear. An auxiliary groove is provided on the side of the adjusting seat near the second rotary driver. The gear is rotatably disposed in the auxiliary groove. A cam is fixedly disposed on the gear. A rack is fixedly disposed in the groove and meshes with the gear. A stabilizing seat is fixedly disposed on the scraper. The cam and the stabilizing seat are rolled together.

[0011] In a preferred embodiment, the rotary telescopic mechanism includes a support base, which is fixedly mounted on the processing table. A rotary driver is fixedly mounted on the support base, and a pulley is fixedly mounted on the output end of the rotary driver. A pulley is rotatably mounted on the support base. The pulley and the pulley are connected by the same belt drive. A circular hole is opened on the pulley, and a drive rod is slidably mounted in the circular hole. The drive rod is fixedly mounted to the screw press.

[0012] In a preferred embodiment, a linear driver is fixedly mounted on the support base, and a connecting seat is fixedly mounted on the output end of the linear driver. The end of the drive rod away from the screw press is rotatably mounted with the connecting seat.

[0013] In a preferred embodiment, a protruding rib is fixedly provided on the drive rod, and a slot is provided on the inner wall of the circular hole, with the protruding rib slidably disposed in the slot.

[0014] In a preferred embodiment, a collection hopper is fixedly installed on the processing table, and the collection hopper is located below the oil outlet hood.

[0015] In a preferred embodiment, a discharge hood is fixedly provided at the end of the pressing cylinder away from the drive rod, and the opening of the discharge hood is oriented towards the processing table.

[0016] The beneficial effects of this invention are as follows: This invention utilizes a rotating telescopic mechanism. After the pressing process is completed, the screw is first driven to move to the left inside the pressing cylinder. Then, the slag cleaning unit contacts the inner wall of the pressing cylinder. Finally, the screw is driven to move to the right, causing the slag cleaning unit to peel off the residue adhering to the inner wall of the pressing cylinder. This prevents the residue inside the pressing cylinder from growing mold and eliminates potential food hygiene hazards.

[0017] This invention uses a positioning mechanism to adjust the movement of the seat so that the gear and rack mesh. The rotation of the gear drives the cam to rotate synchronously. The cam is fixedly connected to the stabilizing seat, which means that the cam can rigidly lock the scraper, thus improving the stability of cleaning residues on the inner wall of the pressing cylinder.

[0028] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Refer to the instruction manual appendix Figures 1 to 3 A pressing and processing device for sesame oil production includes a processing table 1, an oil pressing mechanism 2 fixedly installed on the processing table 1, and an oil pressing mechanism 2 including a pressing cylinder 21 fixedly installed on the processing table 1. An oil outlet cover 22 and a feeding hopper 23 are provided on the pressing cylinder 21. A screw press 3 is installed inside the pressing cylinder 21, and a rotating telescopic mechanism 4 is also installed on the processing table 1. The driving end of the rotating telescopic mechanism 4 is fixedly installed with the end of the screw press 3. The raw material to be pressed enters the pressing cylinder 21 through the feed hopper 23. The driving end of the rotating telescopic mechanism 4 drives the screw press 3 to rotate and press the raw material. The sesame oil formed by pressing is discharged through the oil outlet hood 22. A slag cleaning unit 5 is installed inside the screw press 3. The slag cleaning unit 5 peels off the residue adhering to the inner wall of the pressing cylinder 21 by adhering to the inner wall of the screw press 3. The driving end of the rotating telescopic mechanism 4 drives the screw press 3 to move along the length of the pressing cylinder 21 so that the residue in the pressing cylinder 21 is discharged through its end.

[0030] A collection hopper 11 is fixedly installed on the processing table 1, and the collection hopper 11 is located below the oil outlet cover 22.

[0031] A discharge hood is fixedly installed at the end of the pressing cylinder 21 away from the drive rod 45, and the opening of the discharge hood faces the processing table 1.

[0032] It should be noted that, referring to Figure 3 The screw press 3 located inside the pressing cylinder 21 includes a conveying section and a pressing section. The conveying section of the screw press 3 is threaded, and its operating principle is similar to that of the screw conveyor in the "auger conveyor". The screw press 3 conveys raw materials by rotating. The discharge end of the feed hopper 23 is located in the conveying section of the screw press 3. The pressing section of the screw press 3 is a smooth cylinder. The gap between the smooth cylinder and the inner wall of the pressing cylinder 21 is the pressing zone. When the raw material passes through the pressing zone, the oil inside is squeezed out to achieve the pressing effect.

[0033] It should also be noted that the oil outlet cover is composed of multiple rings tightly fitted together, with the same oil outlet hole between two adjacent rings. The pressing cylinder 21 has multiple oil discharge holes, which are connected to the corresponding oil outlet holes. The pressed oil is discharged through the oil discharge holes.

[0034] Furthermore, the right end of the pressing cylinder 21 is open, so that after the oil in the raw material is pressed out, the residue will be discharged directly through the open end.

[0035] The specific implementation scenario is as follows: The screw press 3 is driven to rotate, and the raw material to be pressed is fed into the pressing cylinder 21 through the feed hopper 23. The conveying section of the screw press 3 directs the raw material towards the pressing section. As more and more raw material enters the pressing area, it is squeezed, and the oil within is squeezed out. The oil is discharged through the oil outlet. As raw material continuously enters the pressing area, the residue moves from left to right within the pressing cylinder 21 and is eventually automatically discharged from the pressing cylinder 21. This process repeats continuously, achieving uninterrupted pressing. When the pressing process is completed, the feeding into the feed hopper 23 stops, and the press... No new raw materials enter the pressing area. At this time, the residue at the pressing area is tightly attached to the inner wall of the pressing cylinder 21, forming a compact annular cake-shaped residue on the inner wall of the pressing cylinder 21. By rotating the telescopic mechanism 4, the screw 3 is driven to move to the left inside the pressing cylinder 21. Then, the slag cleaning unit 5 contacts the inner wall of the pressing cylinder 21, and the screw 3 is driven to move to the right inside the pressing cylinder 21. The slag cleaning unit 5 contacts the inner wall of the pressing cylinder 21, causing the residue attached to the inner wall of the pressing cylinder 21 at the pressing area to fall off. As the screw 3 continues to move to the right, the residue inside the pressing cylinder 21 will be completely discharged.

[0036] Compared with existing technologies, after the pressing process is completed, the screw 3 is first driven to move to the left inside the pressing cylinder 21, and then contacts the inner wall of the pressing cylinder 21 through the slag cleaning unit 5. Then the screw 3 is driven to move to the right, so that the slag cleaning unit 5 can peel off the residue stuck to the inner wall of the pressing cylinder 21, thus preventing the residue inside the pressing cylinder 21 from growing mold and eliminating potential food hygiene hazards.

[0037] Refer to Appendix 3 of the instruction manual. Figure 4 To facilitate the rotation and movement of the screw press 3 within the pressing cylinder 21, the rotary telescopic mechanism 4 specifically includes a support base 41, which is fixedly mounted on the processing table 1. A rotary driver 42 is fixedly mounted on the support base 41, and a pulley 1 is fixedly mounted on the output end of the rotary driver 42. A pulley 2 is rotatably mounted on the support base 41, and the pulleys 1 and 2 are connected by the same belt drive. A circular hole is provided on the pulley 2, and a drive rod 45 is slidably mounted within the circular hole. The drive rod 45 is fixedly mounted to the screw press 3. A linear driver 43 is fixedly mounted on the support base 41, and a connecting seat 44 is fixedly mounted on the output end of the linear driver 43. The end of the drive rod 45 away from the screw press 3 is rotatably mounted to the connecting seat 44. A protruding rib is fixedly mounted on the drive rod 45, and a groove is provided on the inner wall of the circular hole, with the protruding rib slidably mounted within the groove.

[0038] It should be noted that the rotary actuator 42 is a motor, and the linear actuator 43 is a hydraulic cylinder.

[0039] It should also be noted that when the rotary driver 42 is started, the output of the rotary driver 42 drives the pulley 1 to rotate, and the pulley 1 drives the belt to make the pulley 2 rotate synchronously, thereby achieving the effect of the output of the rotary driver 42 driving the drive rod 45 to rotate. When it is necessary to drive the screw 3 to move along the length of the pressing cylinder 21, the linear driver 43 is started. The output of the linear driver 43 drives the connecting seat 44 to move, and the connecting seat 44 drives the drive rod 45 to move, thereby achieving the effect of the output of the linear driver 43 driving the screw 3 to move along the length of the pressing cylinder 21. Simultaneously starting the rotary driver 42 and the linear driver 43 can achieve the effect of the screw 3 rotating and moving simultaneously inside the pressing cylinder 21.

[0040] Refer to the instruction manual appendix Figures 3 to 5 In order to efficiently remove the residue adhering to the inner wall of the pressing cylinder 21 in the pressing area, the slag cleaning unit 5 specifically includes a slag cleaning mechanism 51. The slag cleaning mechanism 51 includes an air-inflating expansion ring 511. A groove is opened in the screw 3, and a through hole is opened on the inner wall of the groove. The air-inflating expansion ring 511 is located in the through hole. An air inlet pipe 512 is fixedly connected to the air-inflating expansion ring 511. A fixing seat 513 is fixedly installed in the groove, and the air-inflating expansion ring 511 is sleeved on the fixing seat 513.

[0041] It should be noted that the end of the air inlet pipe 512 away from the inflation ring 511 is connected to an air pump. The output end of the air pump is rotatably set with the end of the air inlet pipe 512. After the air pump is started, it can increase the pressure inside the inflation ring 511, causing the inflation ring 511 to expand.

[0042] It should also be noted that after the pressing process is completed, the screw 3 is driven to move to the left, and then the air pump pressurizes the air expansion ring 511 to expand it. After the air expansion ring 511 expands, it contacts the inner wall of the pressing cylinder 21. Then, the air expansion ring 511 is kept in an expanded position, and the screw 3 is driven to move to the right inside the pressing cylinder 21. The side of the expanded air expansion ring 511 contacts the residue stuck to the inner wall of the pressing cylinder 21. As the screw 3 continues to move to the right, the air expansion ring 511 can scrape off the residue stuck to the inner wall of the pressing cylinder 21.

[0043] Unlike the above-mentioned technical solution that uses an inflatable expansion ring 511 to expand and contact the inner wall of the pressing cylinder 21 to scrape off the residue on the inner wall of the pressing cylinder 21, this embodiment also provides another solution for the slag removal unit 5, which uses a telescopic scraper 524 to clean off the residue adhering to the inner wall of the pressing cylinder 21. Specifically, refer to the appendix of the instruction manual. Figure 6 and Figure 7The slag cleaning unit 5 includes a second slag cleaning mechanism 52, which includes a second rotary driver 521. The second rotary driver 521 is fixedly installed in a groove, and a threaded rod 522 is fixedly installed on the output end of the second rotary driver 521. An adjusting seat 523 is slidably installed in the groove and is threadedly connected to the threaded rod 522. A sliding groove is provided on the adjusting seat 523, and a scraper 524 is slidably installed in the sliding groove. An elastic element 525 is provided between the scraper 524 and the inner wall of the sliding groove. The end of the screw press 3 causes the scraper 524 to slide in the sliding groove by squeezing it. A placement groove is provided at the end of the screw press 3, and a roller 31 is rotatably installed in the placement groove. An inclined surface 5241 is provided on the scraper 524, and the roller 31 rolls with the inclined surface 5241.

[0044] It should be noted that the rotary drive 521 is a motor, and the threaded rod 522 is fixedly mounted on the output end of the motor. The power supply method of the motor is a mature existing technology and will not be elaborated on here.

[0045] It should also be noted that the inclination angle of the inclined surface 5241 is set to 45°, the elastic element 525 is set as a spring, the spring is fixedly set on the scraper 524, and the end of the spring away from the scraper 524 is attached to the inner wall of the groove.

[0046] In this embodiment, multiple scrapers 524 are arranged along the circumferential direction of the screw press 3, and the initial state of the scrapers 524 is as follows: Figure 6 As shown, the end of the scraper 524 is lower than the side of the screw 3, that is, the length of the line segment connecting the ends of two corresponding scrapers 524 is less than or equal to the length of the screw 3 diameter. When it is necessary to scrape off the residue on the inner wall of the pressing cylinder 21, the screw 3 is first driven to move to the left, and then the second rotary driver 521 is driven. The rotary driver adjustment seat 523 at the output end of the second rotary driver 521 moves to the right inside the screw 3. When the adjustment seat 523 moves to the right, under the action of the elastic force of the elastic element 525, the scraper 524 further slides out of the groove. At this time, the length of the line segment connecting the ends of two corresponding scrapers 524 is greater than the length of the screw 3 diameter. The end of the scraper 524 contacts the inner wall of the pressing cylinder 21, and then the screw 3 is driven to move to the right. The end of the scraper 524 can peel off the residue adhering to the inner wall of the pressing cylinder 21.

[0047] Unlike the aforementioned technical solutions that use an inflatable expansion ring 511 to expand and contact the inner wall of the pressing cylinder 21 to scrape off residue, or a telescopic scraper 524 to clean residue adhering to the inner wall of the pressing cylinder 21, this embodiment provides another solution: combining the first cleaning mechanism 51 and the second cleaning mechanism 52. When it is necessary to clean residue adhering to the inner wall of the pressing cylinder 21 in the pressing area, the screw 3 is first driven to move to the left, and then the scraper 524 is driven to extend and contact the inner wall of the pressing cylinder 21. 1. The inner wall is contacted, and then the inflation expansion ring 511 expands to contact the inner wall of the pressing cylinder 21. After the screw 3 is driven to move to the right, the scraper 524 scrapes off the residue on the inner wall of the pressing cylinder 21. After expansion, the side of the inflation expansion ring 511 further assists in pushing the residue still adhering to the pressing cylinder 21. Combined with the rotation of the screw 3, centrifugal force is generated. When the screw 3 extends out of the pressing cylinder 21, the residue inside the pressing cylinder 21 is completely removed. At this time, the discharge hood can be optimized so that it slides in the pressing cylinder 21 or is removed.

[0048] Refer to the instruction manual appendix Figure 8 and Figure 9 Since the scraper 524 is flexibly supported by the elastic element 525, and the residue adhering to the inner wall of the pressing cylinder 21 is relatively compact, if the scraper 524 peels off the residue, the harder and more compact residue will cause the scraper 524 to slide into the groove and squeeze the elastic element 525, which will affect the cleaning effect. That is, the flexible limit has a certain uncertain negative impact. In order to solve this problem, a positioning mechanism 6 is provided in the adjusting seat 523. The positioning mechanism 6 includes a gear 62. An auxiliary groove is opened on the side of the adjusting seat 523 near the rotating drive 521. The gear 62 is rotatably set in the auxiliary groove. A cam 63 is fixedly set on the gear 62. A rack 61 is fixedly set in the groove. The rack 61 meshes with the gear 62. A stabilizing seat is fixedly set on the scraper 524. The cam 63 and the stabilizing seat are rolled.

[0049] It should be noted that, referring to Figure 9 When the adjusting seat 523 moves to the right inside the screw press 3, the scraper 524 slides out of the groove under the action of the elastic force of the elastic element 525. The end of the scraper 524 contacts the inner wall of the pressing cylinder 21. The movement of the adjusting seat 523 causes the gear 62 and the rack 61 to mesh. The rotation of the gear 62 can drive the cam 63 to rotate synchronously. The cam 63 is fixedly connected to the stabilizing seat, that is, the cam 63 can rigidly lock the scraper 524. Compared with the elastic locking of the single elastic element 525, it can improve the stability of cleaning the residue on the inner wall of the pressing cylinder 21.

[0050] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
