Description

A sesame drying system for producing antioxidant sesame oil Technical Field

[0001] The invention relates to the technical field of antioxidant sesame oil production, in particular to a sesame drying system for making antioxidant sesame oil. Background Art

[0002] Sesame is an important oil crop, cultivated worldwide. Sesame oil is rich in unsaturated fatty acids and has high nutritional value. Compared with other vegetable oils, sesame oil has greater oxidative stability. As the roasting temperature of sesame husks increases, the lignin structure in the husks produces more phenolic hydroxyl groups. Lignin degradation products inhibit the oxidation of sesame oil, and the antioxidant capacity of lignin degradation products increases with rising roasting temperature. Therefore, sesame oil made from roasted sesame seeds has higher oxidative stability than unroasted sesame seeds. Furthermore, the flavor and oxidative stability of sesame oil from roasted sesame seeds are superior to those from peeled sesame seeds.

[0046] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings. Example 1

[0047] As shown in Figures 1-2 and 7-12, a sesame drying system for producing antioxidant sesame oil includes:

[0048] A conveying mechanism 1, which is disposed on a frame 100 and is used to convey sesame seeds for processing;

[0049] Along the transmission direction of the transmission mechanism 1, there are arranged in sequence a pre-treatment station I, a first reaction station II, a water removal station III, a second reaction station IV, and a drying station V arranged before and after the second reaction station IV;

[0050] The pre-treatment station I is provided with a crushing mechanism 2 for making depressions on the surface of the sesame seeds to increase the contact surface; the first reaction station II is provided with a hydrothermal pretreatment mechanism 3 for causing a hydrolysis reaction on the surface of the sesame seeds; the dehydration station III is provided with a drying mechanism 4 for removing water from the surface of the sesame seeds; the second reaction station IV is provided with an extraction mechanism 5 for extracting lignin by reacting ethanol on the surface of the sesame seeds; and the drying station V is provided with a drying mechanism 6 for evaporating water from the surface of the sesame seeds;

[0051] The drying mechanism 4 includes a water absorption component 41 arranged above the transmission mechanism 1 and used to initially absorb excess water on the sesame seeds and the transmission mechanism 1, a drainage component 42 arranged above the water absorption component 41 and used to drain the water in the water absorption component 41 again, and a receiving component 43 arranged on one side of the drainage component 42 and used to collect the discharged water.

[0052] In the present embodiment, by providing a hydrothermal pretreatment mechanism 3 and an extraction mechanism 5, the hydrothermal pretreatment is performed to preliminarily cause the destruction of the lignin and carbohydrate cross-linking structure in the sesame epidermis, the change of the cell wall component structure, and the interruption of hydrogen bonds in the crystalline cellulose. Subsequently, the lignin in the cell wall is extracted by a 95% ethanol solution, and then the ethanol is removed by evaporation. Finally, the water is removed by drying, so that the lignin remains on the sesame. After extrusion and refining, the lignin enters the sesame oil, thereby improving the antioxidant capacity of the sesame oil. This solves the technical problem that the traditional sesame oil pressing process cannot fully extract the antioxidant lignin component in the sesame skin and the resources inside the sesame are not fully utilized.

[0053] In detail, the sesame seeds are first moved to the transmission mechanism 1 after being cleaned, selected and dried, and then arrive at the pre-treatment station I driven by the transmission mechanism 1, and the pressing and depression treatment of the sesame surface is completed under the action of the rolling mechanism 2. Then, the sesame seeds are fully contacted with hot water in the first reaction station II so that the internal components of the sesame skin are changed. Subsequently, most of the water on the sesame seeds is removed by the drying mechanism 4 at the dehydration station III, and the water on the surface of the sesame seeds is removed by the drying mechanism 6. Next, the lignin inside the sesame epidermis is extracted by the extraction mechanism 5 at the second reaction station IV. After sufficient extraction, the ethanol on the surface of the sesame seeds is evaporated with the assistance of the drying mechanism 6. Finally, the sesame seeds are transferred to a roaster for roasting.

[0054] Further, as shown in Figures 1-3, the transmission mechanism 1 includes two transmission wheels 11 connected to the frame 100, a first motor 12 connected to the frame 100 and with its output end connected to the transmission wheels 11, and a conveyor belt 13 wound around the two transmission wheels 11.

[0055] In this embodiment, the transmission mechanism 1 is provided to drive the sesame seeds for transmission processing on the one hand, and to assist the work of the crushing mechanism 2 and the drying mechanism 4 on the other hand.

[0056] In detail, after the sesame seeds reach the transmission mechanism 1, they are driven by the first motor 12 and are driven by the transmission wheel 11 and the conveyor belt 13 to be transmitted forward for processing.

[0057] It should be noted that the sesame seeds arrive at the transmission mechanism 1 in a single-layer distribution manner, which facilitates improving the implementation effect of subsequent work.

[0058] Further, as shown in Figures 1-4, the crushing mechanism 2 includes a pressing component 21 arranged above the transmission mechanism 1 and used to crush the sesame seeds to form a depression, and a cleaning component 22 arranged on one side of the crushing component 21 and used to sweep away the sesame seeds adhering to the crushing component 21.

[0059] In this embodiment, by setting the extrusion component 21 and the cleaning component 22 in the crushing mechanism 2, the two groups of extrusion components 21 and the cleaning components 22 cooperate so that when the first group of extrusion components 21 is used, one side surface of the sesame seeds is squeezed to form a depression, and then swept down from the surface of the extrusion component 21 under the action of the first group of cleaning components 22. The sesame seeds rotate during the falling process, and part of the sesame seeds can be turned over. Then, under the action of the second group of extrusion components 21, the other side is also successfully squeezed out a depression, which facilitates the improvement of the reaction efficiency of the sesame seeds in subsequent reaction work.

[0060] In detail, during the transmission process of sesame on the transmission mechanism 1, the extrusion component 21 is first squeezed on its surface to form a depression, and then the sesame is swept off the extrusion component 21 under the action of the cleaning component 22, so that the sesame returns to the top of the transmission mechanism 1 again.

[0061] It should be noted that the extrusion assembly 21 and the cleaning assembly 22 can be provided in multiple groups so as to fully form depressions on the surfaces of both sides of the sesame seeds to improve the processing efficiency.

[0062] Furthermore, as shown in Figures 3-4, the extrusion assembly 21 includes two laminating rollers 211 connected to the frame 100, a plurality of spikes 212 provided on the laminating rollers 211, a rotating shaft 213 connected to the frame 100, two turning gears 214 respectively connected to the rotating shaft 213 and the output end of the first motor 12 and meshing with each other for transmission, a belt transmission member 215 connected to the rotating shaft 213 and the laminating rollers 211, and a first sprocket chain transmission member 216 connected to the two laminating rollers 211;

[0063] The cleaning assembly 22 includes two rotating rods 221 connected to the frame 100 and connected to the laminating roller 211 through a first sprocket chain transmission member 216, and multiple groups of bristles 222 connected to the rotating rods 221 and used to clean the surface of the laminating roller 211.

[0064] In this embodiment, the power of the first motor 12 is transmitted to the extrusion component 21 and the cleaning component 22 through the belt transmission component 215, thereby saving power resources. At the same time, under the action of the cleaning component 22, the sesame seeds can complete the flipping process, thereby facilitating the formation of depressions on both sides of the sesame seeds.

[0065] In detail, first, at the first group of rolling components, the rolling roller 211 is driven to rotate by the first motor 12, the steering gear 214 and the belt transmission 215, and then the rolling roller 211 squeezes the surface of the sesame seeds through the spikes 212 on the surface to form a depression. Since part of the sesame seeds are adhered to the spikes 212, the corresponding rotating rod 221 is driven to rotate under the action of the first sprocket chain transmission 216, and then the sesame seeds are swept down by the bristles 222, and the sesame seeds are turned over when falling, and then the depression is pressed on the other side at the second group of rolling components.

[0066] It should be noted that, under the action of the steering rack, the rotation direction of the two sets of laminating rollers 211 is opposite to the direction of the conveying wheel 11, and the traveling speed of the surface of the laminating rollers 211 is consistent with the traveling speed of the conveyor belt 13.

[0067] Further, as shown in FIG5 , the hydrothermal pretreatment mechanism 3 and the extraction mechanism 5 both include a guide assembly 31 provided on the transmission mechanism 1 and used to adjust the conveying direction of the transmission mechanism 1 , and a spray assembly 32 provided on the frame 100 and used to spray reactants on the sesame seeds.

[0068] In this embodiment, by setting up the hydrothermal pretreatment mechanism 3 and the guide component 31 and the spray component 32 in the extraction mechanism 5, the sesame seeds can be lifted up first under the action of the guide component 31 and then fall freely. During the process, the spray component 32 is used to fully soak the outer surface of the sesame seeds, which reduces the use of water resources and facilitates the implementation of subsequent preliminary drying work.

[0069] In detail, first, the conveyor belt 13 forms a certain slope under the action of the guide component 31, and then the sesame seeds can fall freely here. At the same time, with the help of the spray component 32, a small amount of water can be used to fully soak the surface of the sesame seeds. Subsequently, at the extraction mechanism 5, ethanol can also be fully contacted with the sesame skin.

[0070] Further, as shown in FIG6 , the guide assembly 31 includes a first guide wheel 311 , a second guide wheel 312 , a third guide wheel 313 and a fourth guide wheel 314 , which are sequentially arranged on the frame 100 close to the conveyor belt 13 ;

[0071] The spray assembly 32 includes a first spray plate 321 and a second spray plate 322 arranged on the frame 100, a storage box 324 connected to the frame 100 and connected to the first spray plate 321 and the second spray plate 322 through a transmission pipe 323, and a scraper 325 connected to the top of the first spray plate 321 and arranged in contact with the conveyor belt 13.

[0072] In this embodiment, a scraper 325 is provided that is in contact with the conveyor belt 13, so that some sesame seeds stuck to the conveyor belt 13 can be scraped off, and the first spray plate 321 is vertically arranged and the second spray plate 322 is inclined. The two cooperate with each other so that when the sesame seeds fall, they are tilted at a certain position under the action of the first spray plate 321, preventing them from bouncing upward after falling vertically and causing a certain accumulation, which affects the distribution of the sesame seeds on the conveyor belt 13. Subsequently, the second spray plate 322 prevents the sesame seeds from bouncing higher and separating from the conveyor belt 13.

[0073] In detail, first, under the action of the first guide wheel 311, the second guide wheel 312, the third guide wheel 313 and the fourth guide wheel 314, the transmission direction of the conveyor belt 13 changes, and the sesame seeds begin to move along the transmission direction of the conveyor belt 13, and then fall freely at the top. During this process, the storage box 324 transmits hot water to the first spray plate 321 and the second spray plate 322 through the transmission pipe 323 and sprays it out, fully soaking the surface of the sesame seeds. Finally, the sesame seeds fall on the conveyor belt 13 and continue to be transported forward.

[0074] It should be noted that the hydrothermal pretreatment mechanism 3 has the same structure as the extraction mechanism 5 , the difference being that the storage box 324 contains hot water and ethanol respectively, and a pumping device is provided inside the storage box 324 .

[0075] Further, as shown in Figures 7-8, the water absorption component 41 includes a mounting frame 411 with two groups of limiting holes 410, a second motor 413 connected to the mounting frame 411 and having a driving rod 412 connected to the output end, an adjustment plate 415 connected to the driving rod 412 and having waist-shaped grooves 414 at both ends, a cleaning plate 417 connected to the mounting frame 411, and a sponge wheel 416 respectively connected to the two limiting holes 410 and driven to move up and down in the limiting holes 410 through the waist-shaped grooves 414.

[0076] In this embodiment, by providing the water absorption component 41, the water on the surface of the sesame and the conveyor belt 13 can be quickly removed, thereby accelerating the drying of the sesame, and the alternating operation of the two sets of sponge wheels 416 ensures the continuous implementation of the drying work.

[0077] In detail, when the sesame seeds soaked in hot water move to the position of the water absorption component 41, the sponge wheel 416 and the conveyor belt 13 first contact each other, and then the transmission belt drives the sponge wheel 416 to rotate synchronously when the sesame seeds are close to the sponge wheel 416, most of the water on the surface of the sesame seeds and the surface of the conveyor belt 13 is removed through the absorption of the sponge wheel 416, and then the cleaning plate 417 is used to scrape off the sesame seeds stuck to the surface of the sponge wheel 416. When the sponge wheel 416 absorbs water to a specified value, the second motor 413 works by driving the driving rod 412 and the adjusting plate 415 to rotate together, and then under the action of the adjusting plate 415, the waist-shaped groove 414 on one side drives the sponge wheel 416 to rise, and the other side drives the other sponge wheel 416 to fall, working alternately.

[0078] It should be noted that the two sponge wheels 416 can be connected when alternating to ensure that the water removal work of the sesame is carried out normally.

[0079] Further, as shown in Figures 7-11, the drainage assembly 42 includes two drainage plates 422 connected to the mounting frame 411 and respectively connected to the first racks 421, a first gear 424 connected to the column 423 and meshing with the two first racks 421 for transmission, a driving rack 425 connected to the column 423 and meshing with the first gear 424 for transmission, and a support arm 426 connected to the driving rack 425 and used to cooperate with the sponge wheel 416 to drive the driving rack 425 to move;

[0080] The receiving assembly 43 includes a second gear 431 connected to the end of the driving rod 412, a gear ring 433 connected to the mounting column 432 and meshing with the second gear 431 for transmission, two hollow guide rods 435 connected to the gear ring 433 and with receiving plates 434 connected to the ends, and a receiving tube 436 arranged on the mounting column 432.

[0081] It is worth mentioning here that the water absorption component 41 is driven by the power of the second motor 413, which drives the drainage component 42 and the receiving component 43 to work at the same time, greatly improving work efficiency, saving power resources, and improving the degree of automation.

[0082] In detail, when the sponge wheel 416 rises, one end contacts the support arm 426 on the driving rack 425, and then drives the driving rack 425 to move upward through the support arm 426, and then drives the rack 425 to drive the first gear 424 to rotate, and the first gear 424 drives the two groups of first racks 421 to move, and then drives the drainage plates 422 on both sides to approach each other to squeeze the sponge wheel 416 to drain water; when the sponge wheel 416 reaches the drainage plate 422 position, the driving rod 412 drives the second gear 431 to rotate, and the second gear 431 drives the gear ring 433 on the mounting column 432 to rotate, and the gear ring 433 then drives the hollow guide rods 435 on both sides connected to the receiving plate 434 to rotate, so that the receiving plate 434 moves to the bottom of the sponge wheel 416 that needs to be drained, and receives the discharged water and diverts it into the receiving bucket.

[0083] Furthermore, as shown in Figures 13-15, the drying mechanism 6 includes multiple groups of blowing components 61 arranged above the transmission mechanism 1 and used to increase the evaporation rate of water on the surface of sesame seeds, and multiple groups of vibration components 62 arranged below the transmission mechanism 1 and used to drive the sesame seeds to vibrate and accelerate evaporation.

[0084] In this embodiment, by setting the blowing component 61 and the vibration component 62 in the drying mechanism 6 to cooperate with each other, the moisture remaining on the surface of the sesame can be quickly removed, and under the action of the vibration component 62, the sesame jumps and turns continuously, thereby ensuring that insufficient drying will not occur.

[0085] In detail, after the sesame seeds pass through the drying mechanism 4, there is still a certain amount of moisture on the surface. Then, under the action of the wind force of the blowing component 61, the moisture on the surface of the sesame seeds begins to evaporate rapidly. At the same time, the vibration component 62 drives the sesame seeds to turn over to ensure the quality of drying.

[0086] It should be noted that the two sets of air blowing components 61 are respectively arranged before and after the extraction mechanism 5, and are used for removing water and ethanol respectively. Example 2

[0087] As shown in Figures 13-15, the same or corresponding components as those in the first embodiment are marked with the same reference numerals as those in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The differences between the second embodiment and the first embodiment are:

[0088] Further, as shown in Figures 13-15, the air blowing assembly 61 includes a plurality of fans 611 connected to the rack 100 and a heating wire 612 connected to the rack 100 and arranged below the fans 611;

[0089] The vibration assembly 62 includes a slide 621 arranged on the frame 100 and located below the heating wire 612, a slide plate 622 connected to the slide 621, a plurality of vibration rods 623 connected to the slide plate 622 and passing through the slide 621, a plurality of springs 624 connected between the slide 621 and the slide plate 622, a third motor 625 connected to the frame 100, a cam 627 connected to the output end of the third motor 625 through a round rod 626, and a second sprocket chain transmission member 628 connecting multiple round rods 626.

[0090] It is worth mentioning that the cam 627 in the vibration component 62 rotates rapidly, thereby driving the vibration rod 623 to vibrate up and down, causing the conveyor belt 13 in the contact part to be driven to vibrate, and the sesame seeds in the contact part are bounced up and turned over at the same time. At this time, the downward wind force of the blowing component 61 can speed up the drying efficiency while preventing the sesame seeds from spreading outward.

[0091] In detail, when the sesame seeds reach the drying mechanism 6, the multiple fans 611 and the heating wire 612 above start working to transmit hot air to the sesame seeds. At the same time, the third motor 625 drives the round rod 626 and the cam 627 to rotate. The cam 627 drives the slide 622 to move upward, and then moves downward under the action of the spring 624, thereby driving the vibration rod 623 to move up and down to cause vibration.

[0092] It should be noted that the round rods 626 of the two sets of vibration components 62 are connected through the second sprocket chain transmission member 628 to work.

[0093] Working process: First, after washing, selecting and drying, the sesame seeds are moved to the transmission mechanism 1, and driven by the transmission mechanism 1 to reach the pre-treatment station I, and the pressing and concave treatment of the sesame surface is completed under the action of the rolling mechanism 2. Then, the sesame seeds are fully contacted with hot water in the first reaction station II to change the internal components of the sesame skin. Subsequently, most of the water on the sesame seeds is removed by the drying mechanism 4 at the dehydration station III, and the water on the surface of the sesame seeds is removed by the drying mechanism 6. Next, the lignin inside the sesame skin is extracted by the extraction mechanism 5 at the second reaction station IV. After sufficient extraction, the ethanol on the surface of the sesame seeds is evaporated with the assistance of the drying mechanism 6. Finally, the sesame seeds are transferred to the roaster for roasting. The roasting process includes a heating stage I: flattening the black sesame seeds on the baking tray to a thickness of about 0.9 cm, The oven temperature is adjusted to 90-98°C, the temperature is increased at a uniform rate, and then the drying is continued until the amount of water introduced into the black sesame seeds is reduced to 42%-51% of the total weight introduced; a dehydration and evaporation stage: when the air humidity in the oven reaches 71%-79%, heating is stopped, and the oven door is opened for natural ventilation for 12-21 minutes each time until the air humidity drops to 55%-61%; a heating stage II: when the humidity in the oven reaches 55%-61%, the temperature is adjusted to 91-93°C, and drying is continued until the water loss rate reaches 98%-98.5%, and heating is stopped; an equilibrium stage: heating is stopped, and after 25 minutes, the black sesame seeds are removed. At this time, lignin in the sesame hulls remains on the surface. When the oil is subsequently squeezed out, the lignin is collected along with the sesame oil, and the resulting sesame oil has a more significant antioxidant effect.
