Description

Technical Field

[0001] The invention relates to the technical field of sesame oil pressing equipment, and in particular to low-temperature sesame oil pressing equipment and a working method thereof. Background Art

[0002] Sesame oil pressing is a process for making high-quality sesame oil. By pressing sesame oil at a lower temperature, the nutrients and flavor of sesame are retained, making the oil taste richer and have a special aroma. This process can effectively retain the vitamins, minerals and antioxidants in sesame, which is beneficial to human health. It also improves the quality and value of sesame oil.

[0003] The main defects of the prior art are: the main reason why air needs to be avoided when low-temperature sesame seeds enter the pressing chamber is to prevent the occurrence of oxidation reactions. The oxygen in the air will cause the oil in the sesame seeds to oxidize, affecting the quality and taste of the oil. When sesame oil is pressed by a pressing device, when sesame seeds are poured into the pressing chamber inside the pressing device, there will be gaps between the sesame seeds, and there will be air in these gaps. During the pressing process, the sesame oil will come into contact with oxygen in the air, which will cause the sesame oil to oxidize. Oxidation is a chemical reaction that will reduce the quality and taste of the squeezed sesame oil, and even produce bad odors and harmful substances. The freshly squeezed oil will also be oxidized, so the oil pressing environment after the air is sucked out can be filled with nitrogen to form an inert environment for oil pressing.

[0004] Secondly, during the sesame oil pressing process, the position of the sesame seeds inside the oil pressing chamber relative to the pressing plate remains unchanged, causing the pressing force on the sesame seeds to gradually increase as the depth increases. The different pressure intensities lead to uneven pressing of the sesame seeds, which reduces the production capacity of sesame oil. Summary of the invention

[0017] A working method of a low-temperature sesame oil pressing device comprises the following steps:

[0018] S1: The first stage of pressing, by pouring sesame seeds between the pressing chamber and the rotating barrel, starting the hydraulic device, so that the lifting rod drives the support plate and the pressure plate to descend to one-third of the depth inside the pressing chamber, and the sesame seeds inside the pressing chamber are pressed. During the pressing process, the linkage teeth and the sliding frame are engaged, so that the sliding frame drives the lifting plate to rise in the rotating barrel. However, since the area of ​​the pressure plate is larger than the area of ​​the lifting plate, the air pressure entering the oil filter chamber is directly discharged to the outside through the first one-way valve. Before the sesame seeds inside the pressing chamber are flattened and the second stage of pressing is to be carried out, the sesame seeds in the pressing chamber are filled with nitrogen through the nitrogen interface installed on the top of the pressure plate, so that the air in each chamber is basically replaced by nitrogen, so that the nitrogen filled reduces the oxygen content in the air;

[0019] As the pressing plate continuously squeezes the sesame seeds, the sesame seeds are also made closer together, and the internal air is expelled, so that the internal sesame seeds are prevented from contacting with the air during oil extraction;

[0020] S2: The second stage of pressing. After the air inside the sesame is completely discharged, the hydraulic device is turned on to drive the pressing plate to continue to descend to two-thirds of the depth between the pressing chambers. Then the lifting cylinder is turned on to drive the rotating cylinder to descend through the L-shaped connecting rod. The plug connected to the lower end surface of the plug rod is inserted into the sesame that has been pressed in the second stage. The rotating cylinder is turned on to drive the first rotating tooth to rotate at its output end. When the first rotating tooth rotates, it meshes with the second rotating tooth, driving the second rotating tooth and the expansion frame to rotate. The expansion frame rotates inside the sesame to open the internal sesame. The hydraulic device is turned on to drive the pressing plate to rise. The expanded expansion frame rises together, driving the opened sesame to move and rise, thereby driving the opened sesame at the bottom to turn upward;

[0021] S3: Turn on the first motor to drive the first rotating column to rotate, so as to rotate the second rotating column and the missing gear through the belt transmission, and the missing gear and the tooth groove are meshed to drive the pressing chamber to rotate intermittently. After the sesame seeds are turned out upward, the turned out sesame seeds are driven to move to the bottom of the pressing plate to ensure that the turned out sesame seeds can be pressed, and the unturned sesame seeds are moved to the bottom of the L-shaped connecting rod and the rotating cylinder to be turned out again. Repeat the above actions to turn out and press the sesame seeds. After one rotation, start the lifting cylinder to drive the rotating cylinder back to the inside of the fixed sleeve, and the pressing plate will press the turned out sesame seeds more deeply during the downward pressing process. The descending depth will cause the lifting plate to continuously rise airtightly inside the rotating barrel, so that the nitrogen inside the oil filter chamber is continuously reduced on the basis of the original negative pressure, and the reduced nitrogen rises together through the lifting plate, and then is discharged outward through the first one-way valve. Therefore, during each pressing process, the gas inside the oil filter chamber will gradually decrease and finally be completely extracted. Repeat the above operations to repeatedly extract the nitrogen inside the pressing chamber;

[0022] S4: The third stage of pressing, the hydraulic device is turned on to drive the pressing plate to continuously descend to press the sesame seeds, and the second motor is turned on to drive the first transmission rod and the fan to rotate. The fan will blow air into the heat dissipation channel through the air inlet end, and the heat dissipation copper plate installed on the inner wall of the heat dissipation copper plate will be closely attached to the outer wall of the pressing chamber. The heat generated by pressing is thermally transferred to the heat dissipation copper plate, and then discharged to the outside through the air outlet end. The fan blowing and the opening are used for air cooling and heat dissipation, which reduces the heat generated by pressing and maintains low temperature pressing;

[0023] S5: The sesame oil squeezed out continuously will flow down from the oil outlet hole to the inside of the lifting oil collecting barrel, and the second transmission rod will be driven to rotate by the first transmission rod, and the second transmission rod will drive the rotating rod to rotate. When the rotating rod rotates, it will drive the reciprocating screw rod to rotate, so that the connecting frame will reciprocate up and down on the outer wall of its reciprocating screw rod. During the movement, the connecting frame and the lifting oil collecting barrel are fixed to drive the lifting oil collecting barrel to reciprocate up and down inside the support seat. During the upward movement of the lifting oil collecting barrel, the filter cavity is squeezed to reduce the internal air pressure. The air pressure pushes the sesame oil inside the lifting oil collecting barrel, so that the sesame oil is squeezed from the second one-way valve to the inside of the filter screen, and then filtered out from the inside of the filter screen to the outside, and flows out to the inside of the oil outlet cavity. During the downward movement of the lifting oil collecting barrel, the bottom of the lifting oil collecting barrel will squeeze with the inner cavity of the support seat to reduce the internal air pressure of the oil outlet cavity, so that the internal air pressure of the oil outlet cavity pushes the sesame oil, so that the sesame oil is sprayed out from the oil outlet pipe and the third one-way valve, so as to achieve the function of rapid filtration and oil outlet.

[0024] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0025] First, by pouring sesame seeds between the pressing chamber and the rotating barrel, starting the hydraulic device, the lifting rod drives the supporting plate and the pressure plate to descend to a certain depth inside the pressing chamber, and the sesame seeds inside the pressing chamber are pressed. During the pressing process, the linkage teeth and the sliding frame are meshed, so that the sliding frame drives the lifting plate to rise in the rotating barrel. During this process and before pressing, the air between the sesame seeds in the pressing chamber will be squeezed by the pressure plate and pushed into the oil filter chamber from the oil outlet. When the pressure plate descends, the lifting plate rises in the rotating barrel. However, since the area of ​​the pressure plate is larger than the area of ​​the lifting plate, the air pressure entering the oil filter chamber is directly discharged to the outside through the first one-way valve. Before the sesame seeds in the pressing chamber are flattened and the second stage of pressing is to be carried out, nitrogen is filled into the sesame seeds in the pressing chamber through the nitrogen interface installed on the top of the pressure plate, so that the air in each chamber is basically replaced by nitrogen, so that the nitrogen filled reduces the oxygen content in the air, reduces the oxidation rate of the oil product, and extends the shelf life of the oil.

[0026] Second, when squeezing, start the hydraulic device to make the pressure plate continue to descend two-thirds to squeeze the sesame. During the squeezing process, open the lifting cylinder to make the L-shaped connecting rod drive the rotating cylinder to descend, and the plug and plug set at the bottom of the rotating cylinder will be inserted into the sesame. Start the rotating cylinder to drive the first rotating tooth to rotate, and the first rotating tooth and meshing will drive the expansion frame to rotate inside the sesame to open the sesame. Then rotate the hydraulic device to drive the pressure plate and the rotating cylinder to rise, and let the expansion frame drive the expanded sesame to rise and fall together, and turn the sesame upward, so that the sesame at the bottom can be turned upward, and the pressing chamber rotates intermittently. After the sesame is turned upward, the turned-out sesame is driven to move to the bottom of the pressure plate to ensure that the turned-out sesame can be squeezed, and the sesame that has not been turned out is moved to the bottom of the L-shaped connecting rod and the rotating cylinder, and turned out again for squeezing.

[0056] By rotating the missing gear 505, after the sesame seeds are turned out, the pressing chamber 401 is driven to rotate intermittently, and the turned out sesame seeds are moved to the bottom of the pressing plate 304 for pressing, while the unturned sesame seeds are moved to the bottom of the rotating cylinder 310 for turning out again.

[0057] Reference Fig.11 The outer peripheral surface of the heat dissipation channel 402 is fixedly connected with an external block 501, and the bottom of the external block 501 is fixedly installed with a first motor 502. The output end of the first motor 502 passes through the external block 501 and is fixedly connected with a first rotating column 503. The first rotating column 503 is rotatably connected to the external block 501, and the second rotating column 504 is connected to the first rotating column 503 with a transmission.

[0058] By turning on the first motor 502, the first rotating column 503 can be driven to rotate. The first rotating column 503 allows the second rotating column 504 to rotate through the belt transmission, thereby driving the missing gear 505 to rotate. The second rotating column 504 and the first rotating column 503 are connected with the belt transmission.

[0059] A working method of a low-temperature sesame oil pressing device comprises the following steps:

[0060] In the first stage of squeezing, sesame seeds are manually poured into the squeezing chamber to fill the squeezing chamber with sesame seeds, and the hydraulic cylinder is started to make the lifting rod 301 drive the support plate 302 to descend. When the support plate 302 descends, it drives the pressure plate 304 to descend together through the connecting column 303. During the descent, the reinforcing rod 306 is driven to descend together, meshing with the linkage gear 415, driving the linkage gear 415 to rotate, and the linkage gear 415 is meshed with the sliding frame 404, thereby driving the sliding frame 404 to rise inside the slide groove, thereby driving the lifting plate 405 to rise inside the rotating barrel 403;

[0061] During this process and before squeezing, the air between the sesame seeds in the squeezing chamber will be squeezed by the pressing plate 304 and pushed into the oil filter chamber from the oil outlet 409. The lifting plate 405 rises in the rotating barrel 403 while the pressing plate descends. However, since the area of ​​the pressing plate 304 is larger than that of the lifting plate 405, the air pressure entering the oil filter chamber is directly discharged outward through the first one-way valve 406. Before the sesame seeds in the squeezing chamber are flattened and are about to be squeezed in the second stage, nitrogen is charged into the sesame seeds in the squeezing chamber through the nitrogen interface installed on the top of the pressing plate 304, so that the air in each chamber is basically replaced by nitrogen, so that the nitrogen charged reduces the oxygen content in the air, reduces the oxidation rate of the oil product, and prolongs the shelf life of the oil.

[0062] As the pressing plate 304 continuously squeezes the sesame seeds, the sesame seeds are also made closer together, and a small amount of air and nitrogen inside are continuously discharged, so that the sesame seeds inside are prevented from contacting with the air during the oil pressing process, so that the pressing plate 304 can contact the sesame seeds to squeeze the sesame seeds, and the sesame seeds inside the pressing chamber gradually become closer;

[0063] In the above process, the flow direction of nitrogen is; pressing chamber → oil outlet 409 → oil filter chamber → rotating barrel 403 → first one-way valve 406, so that when sesame seeds are filled into the pressing chamber, the trace air (due to its small amount, its influence can be ignored) and nitrogen in the gap are discharged to the outside.

[0064] In the second stage of squeezing, the hydraulic device 2 is turned on to drive the pressure plate 304 to continuously squeeze the poured sesame seeds. When squeezing reaches a certain degree, the lifting cylinder 308 is turned on again, and the rotating cylinder 310 is driven to descend through the L-shaped connecting rod 309, and the plug 313 connected to the lower end surface is inserted into the sesame seeds that have been squeezed in the second stage (during the descent, the lifting plate 405 will continue to rise in the rotating barrel 403, allowing the internal nitrogen to be discharged outward from the first one-way valve 406 to discharge the nitrogen inside the squeezing chamber and the oil filter chamber), and the rotating cylinder 310 is turned on to drive the first rotating tooth 311 to rotate at its output end. When the first rotating tooth 311 rotates, it meshes with the second rotating tooth 314, driving the second rotating tooth 314 and the expansion frame 315 to rotate inside the sesame seeds, thereby propping up the internal sesame seeds, and the expansion frame 315 is turned on. 315 is composed of a connecting rod and a support rod. The connecting rod and the second rotating tooth 314 are fixed at the bottom. When rotating, the support rod is driven to rotate in the sesame. Relative to the vertical connection mode of the connecting rod and the second rotating tooth 314 at the bottom, the support rod and the connection mode of the connecting rod have a certain angle to ensure that the inclined surface of the support rod can drive the sesame to rise together when rising. The hydraulic device 2 is turned on to drive the pressure plate 304 to rise (when the pressure plate 304 rises, the external air will not enter the inside of the pressing chamber and the oil filter chamber through the first one-way valve 406). The expanded expansion frame 315 rises together. The expansion frame 315 will drive the expanded sesame to move and rise, thereby driving the expanded sesame at the bottom to turn upward. When the sesame that has not turned out is inserted into the sesame, the pressure plate 304 continues to squeeze.

[0065] At the same time, the first motor 502 is turned on to drive the first rotating column 503 to rotate, so that the second rotating column 504 and the missing gear 505 are rotated through the belt transmission, and the missing gear 505 is meshed with the tooth groove to drive the pressing chamber 401 to rotate intermittently. After the sesame seeds are turned out upward, the turned-out sesame seeds are driven to move to the bottom of the pressure plate 304, and then the hydraulic device 2 is started to descend, driving the pressure plate 304 to press down so as to squeeze the turned-out sesame seeds, while the sesame seeds that have not been turned out are moved to the bottom of the L-shaped connecting rod 309 and the rotating cylinder 310 through the intermittent rotation of the pressing chamber 401, and turned out again. In this way, when the pressure plate 304 presses the turned-out sesame seeds, the insertion rod 312 and the plug 313, and the expansion frame 315 are moved through the L-shaped connecting rod 309 and the rotating cylinder 310, inserted into the inside of the sesame seeds that have not been turned out, and turned them out. The above actions are repeated to turn out and squeeze the sesame seeds. After the pressing chamber 401 rotates one circle, the lifting cylinder 308 is started to bring The rotating cylinder 310 is moved back to the inside of the fixed sleeve 307, and the diameter of the plug 313 is equal to the diameter of the fixed sleeve 307, so that when the rotating cylinder 310, the plug rod 312, the plug 313 and the expansion frame 315 are moved back to the inside of the fixed sleeve 307, the sesame seeds are prevented from entering the inside of the fixed sleeve 307 from the bottom thereof. In the process that the pressing plate 304 is continuously lifted and lowered to press the turned-out sesame seeds, the pressing plate 304 presses the turned-out sesame seeds in the downward pressing process, so as to press the turned-out sesame seeds at a deeper level, and the descending depth will make the lifting plate 405 continuously rise in an airtight manner inside the rotating barrel 403, so that the nitrogen inside the oil filter chamber is continuously reduced on the basis of the original negative pressure, and the reduced nitrogen is raised together through the lifting plate 405, and then discharged outwardly through the first one-way valve 406, so that in each pressing process, the gas inside the oil filter chamber will gradually decrease, and finally be completely extracted, and the above operation is repeated to repeatedly extract the nitrogen inside the squeezing chamber;

[0066] In the third stage of squeezing, the hydraulic device 2 is turned on to drive the pressing plate 304 to continuously descend to squeeze the sesame seeds. The second motor 702 is turned on to drive the first transmission rod 704 and the fan 705 to rotate. The fan 705 blows air into the heat dissipation channel 402 through the air inlet end. The heat dissipation copper plate 414 installed on the inner wall of the heat dissipation copper plate 414 will be closely attached to the outer wall of the pressing chamber 401. The heat generated by squeezing is thermally conducted to the heat dissipation copper plate 414, and then blown out from the air outlet end. The air is blown by the fan 705 and the opening for air cooling and heat dissipation, thereby reducing the heat brought by squeezing and maintaining low-temperature squeezing.

[0067] After the sesame oil squeezed out in the above stages will flow down from the oil outlet 409 to the inside of the lifting oil collecting barrel 408. During the air cooling and heat dissipation process, the second transmission rod 707 is driven to rotate by the first transmission rod 704. The second transmission rod 707 drives the rotating rod 706 to rotate through the bevel gear pair. The rotating rod 706 drives the reciprocating screw rod 712 to rotate when rotating, so that the connecting frame 711 can reciprocate up and down on the outer wall of its reciprocating screw rod 712. During the movement, the inside of both sides of the connecting frame 711 will slide up and down on the outer wall of the support column 709 to rise and fall, and at the same time, the compression spring 710 is fixed through the connecting frame 711 and the lifting oil collecting barrel 408. When the connecting frame 711 is lifted, it drives the lifting The oil collecting barrel 408 reciprocates up and down inside the support seat 407. During the upward movement of the oil collecting barrel 408, the filter chamber is squeezed. During the process of reducing the air pressure in the filter chamber, the sesame oil inside is continuously pushed out through the second one-way valve 410 and enters the filter screen 411, and then filtered out from the inside of the filter screen 411 to the inside of the oil outlet chamber. During the downward movement of the oil collecting barrel 408, the air pressure inside the oil outlet chamber will gradually decrease, pushing the sesame oil out from the oil outlet pipe 412 and the third one-way valve 413, so as to achieve the function of rapid filtration and oil output. After the sesame seeds are squeezed, the oil pressing chamber assembly 4 can be pulled out through the slide 416 to clean up the sesame seeds that have been squeezed inside.
