Description

Technical Field

[0001] The present invention relates to the technical field of camellia oilseed oil pressing production, and particularly relates to a camellia oilseed cleaning and drying production line. Background Art

[0002] Camellia oil is rich in various nutrients, such as unsaturated fatty acids, especially with a relatively high content of oleic acid. It has good antioxidant properties, helps prevent cardiovascular diseases, and is very beneficial to human health. It is quite popular among consumers in the market. Camellia oil is a woody oil obtained from the seeds of Camellia oleifera Abel in the Theaceae family and is a unique high-quality edible oil in China. The process of pressing camellia oilseeds mainly includes post-harvest pretreatment, oil pressing and other links. In the pretreatment stage, it is necessary to clean the camellia oilseeds to remove impurities, mildewed particles, etc. Subsequently, drying is carried out to reduce the moisture content. An appropriate moisture content can enable the camellia oilseeds to be better pressed during the oil pressing process, improve the oil yield and ensure the quality of the oil product.

[0003] However, in the cleaning link, generally it is necessary to manually select the mildewed or unripe particles. However, some of the mildewed particles only mildew inside and there are no mildew spots on the surface, so it is very difficult to select them. Also, for some unripe particles, although they are the same size as the ripe particles, since the internal cell structure of the unripe oilseeds has not been fully differentiated and matured, and the related physiological processes of oil synthesis have not been fully carried out, they only have a lower weight than the ripe oilseeds while having a similar appearance. At this time, it is very difficult to pick them out, resulting in some mildewed or unripe camellia oilseeds being mixed in. This not only affects the quality of the final camellia oil, but also the harmful substances produced by mildew may remain in the oil, posing a potential threat to the health of consumers. In addition, during the drying process, a large amount of heat energy is directly discharged into the environment without being effectively recycled, causing great waste of energy, increasing the production cost, and not conforming to the concept of modern green and energy-saving production.

[0015] The beneficial effects of the camellia oil seed cleaning and drying production line provided by the present invention are as follows:

[0016] 1. The hot air is continuously blown by the two wind wheels on both sides towards the inside of the second hot steam recovery cover to dry the camellia oil seeds. The dried hot steam will enter the steam spraying pipe in the first sealing cover through the first connecting pipe connected to the upper end of the second hot steam recovery cover. The hot steam containing will be sprayed from the steam spraying pipe onto the camellia oil seeds passing through the lower end of the first sealing cover at the upper end of the screening and conveying device, softening the stubborn stains on the surface of the camellia oil seeds. At the same time, most of the steam in the hot steam remains on the surface of the camellia oil seeds. Part of the hot steam is conveyed to the lower part of the first sealing cover after passing through the screening and conveying device. The first motor below the first sealing cover drives the first wind wheel to rotate, thereby collecting the hot steam passing through the screening and conveying device and conveying it to the wind chamber on the left through the second connecting pipe. The wind wheel drives the drive shaft to rotate, thereby causing the front and rear eccentric vibration wheels to rotate eccentrically to generate centrifugal force, and applying the centrifugal force to the screening and conveying device through the vibration frame. With the cooperation of the buffer support rods at the four corners of the lower end of the screening and conveying device, the screening and conveying device vibrates, thereby causing the camellia oil seeds at the upper end of the screening and conveying device to vibrate. When vibrating, the camellia oil seeds can be turned over, so that the entire surface of the camellia oil seeds will be softened by the hot steam. Furthermore, when the later spray pipe sprays tap water onto the camellia oil seeds, the stubborn stains can be more easily washed away from the surface of the camellia oil seeds, which is beneficial to the cleaning degree of the camellia oil seeds.

[0017] 2. When the drive shaft drives the eccentric vibration wheel to rotate, it synchronously drives the first pulley to rotate, and drives the kicking roller to rotate through the transmission belt. Since the screening and conveying device drives the camellia oil seeds to vibrate, and the immature or mildewed particles in the camellia oil seeds are lighter, these camellia oil seeds will be shaken higher and shaken out from the mature and normal camellia oil seeds. At this time, the kicking belts evenly distributed on the outer circumference of the kicking roller will kick out these immature or mildewed particles, which will fall from the arc-shaped baffle at the upper end of the arc-shaped conveying box into the inside of the arc-shaped conveying box. At the same time, the first small gear drives the first large gear to rotate, and then drives the conveying auger to rotate through the conveying roller, and finally outputs these immature or mildewed particles from the arc-shaped conveying box. By being able to kick out the immature or mildewed particles inside the camellia oil seeds before the hot steam softening, it is realized that there is no need to manually select the immature or mildewed particles in the camellia oil seeds before cleaning, saving labor costs and avoiding the situation that some particles with no mildew on the surface but mildew inside the shell are not selected during manual selection, improving the quality of subsequent oil extraction.

[0018] 3. When the kicking roller rotates to kick out the immature or mildewed particles in the camellia oil seeds, it synchronously drives the cam to rotate, and then through the cooperation of the spring, the limit plate and the limit frame, drives the rack to reciprocate and rub, and then drives the steam spraying pipe to rotate reciprocally through the third small gear, and then evenly sprays the hot steam onto the upper end of the camellia oil seeds conveyed to the lower end of the first sealing cover, realizing more evenly spraying the hot steam onto the surface of the camellia oil seeds, so that the stubborn stains on the surface of the camellia oil seeds can be softened more thoroughly.

[0019] 4. The hot steam inside the air bin is transported to the hot steam spraying pipe through the fourth connecting pipe. When the washed camellia oil seeds pass by the lower end of the second sealing cover, the washed camellia oil seeds can be preheated, enabling the camellia oil seeds to be quickly dried during subsequent drying, which is beneficial to the production efficiency of camellia oil seed pressing.

[0020] 5. After being cooled by the hot steam on the upper right side of the cleaning and conveying device, it is collected by the first hot steam recovery cover at the lower end. The first air blade inside rotates, and then it is sent into the air bin in the middle of the lower end of the drying and conveying device through the third connecting pipe. Similarly, it drives the drying and conveying device to vibrate slightly, making the drying more thorough during the drying process. And the remaining air volume is sent back to the third connecting pipes on both sides through the exhaust pipe and mixed with the air entering the third connecting pipe, enabling the air entering the third connecting pipe to be preheated. After the equipment operates for a period of time, the heat generation of the heating wire can be appropriately reduced, thereby achieving energy savings and extending the service life of the heating wire.

On the left side of the upper end of the screening and conveying device 102, a feeding port 107 is fixedly connected. On the front and rear parts of the left side of the upper end of the cleaning and conveying device 103, mounting plates 1038 are fixedly connected. On the upper left end of the cleaning and conveying device 103, water spray pipes 1039 are evenly distributed. The front and rear ends of the water spray pipes 1039 are fixedly connected in the openings of the mounting plates 1038. On both sides of the lower end of the drying and conveying device 104, drying covers 1044 are fixedly connected. In the middle of the lower end of each drying cover 1044, a second motor 1045 is fixedly connected. On the upper end of each second motor 1045, a second large gear 1046 is fixedly connected. On both sides of each second large gear 1046, a second small gear 1047 is meshed and connected. On the upper end of each second small gear 1047, a second wind blade 1048 is fixedly connected. In the middle of the drying cover 1044, electric heating wires 1049 are evenly distributed.

[0033] In this embodiment, buffer support rods 105 are fixedly connected to the four corners of the screening and conveying device 102 and the drying and conveying device 104. The lower ends of the buffer support rods 105 are fixedly connected to the upper end of the bracket 101. A waste liquid collection pool is fixedly connected directly below the water spray pipes 1039 at the lower end of the cleaning and conveying device 103. The lower ends of the second small gears 1047 are rotatably connected to both sides of the lower end of the drying cover 1044 through rotating rods. Mounting frames 106 are fixedly connected to the front and rear ends of the cleaning and conveying device 103. The lower ends of the mounting frames 106 are fixedly connected to both sides of the upper end of the bracket 101.

[0034] Specifically, start the screening and conveying device 102, the cleaning and conveying device 103, and the drying and conveying device 104, and start the second motor 1045, the heating wire 1049, and the first motor 1026. Connect the water spray pipe 1039 to tap water. The second motor 1045 drives the second wind blade 1048 to rotate through the second large gear 1046 and the second small gear 1047, preheating the inner area of the second hot steam recovery cover 1037 on both sides of the middle of the drying and conveying device 104. Camellia oil seeds are conveyed from the material conveyor belt to the inside of the feed inlet 107, evenly scattered to the upper left side of the screening and conveying device 102, conveyed to the right by the screening and conveying device 102, and dropped to the upper end of the cleaning and conveying device 103, where they are cleaned by the tap water sprayed by the water spray pipe 1039. After cleaning, they are continuously conveyed to the right by the cleaning and conveying device 103 and dropped to the upper end of the drying and conveying device 104, where they are dried when passing under the two second hot steam recovery covers 1037, completing the washing and drying of the camellia oil seeds. After being cooled by the hot steam on the upper right side of the cleaning and conveying device 103, they are collected through the first hot steam recovery cover 1025 at the lower end, and the first wind blade 1027 inside rotates, and then is sent into the air chamber 1029 in the middle of the lower end of the drying and conveying device 104 through the third connecting pipe 1043. Similarly, it drives the drying and conveying device 104 to vibrate slightly, making the drying more thorough during the drying process, and the remaining air volume is sent back to the two third connecting pipes 1043 through the exhaust pipe 1042, mixing with the air entering the inside of the third connecting pipe 1043, so that the air entering the third connecting pipe 1043 can be preheated. After the equipment operates for a period of time, the heat generation of the heating wire 1049 can be appropriately reduced, thereby saving electric energy and prolonging the service life of the heating wire 1049.

[0035] In this embodiment, a first sealing cover 1023 is fixedly connected to the upper right side of the screening and conveying device 102. Second hot steam recovery covers 1037 are fixedly connected to both sides of the upper end of the drying and conveying device 104. The upper ends of the second hot steam recovery covers 1037 are communicated with the right ends of the first connecting pipes 1024. The left ends of the first connecting pipes 1024 are communicated with a steam spraying pipe 1022. The front and rear ends of the steam spraying pipe 1022 are fixedly connected to the middle parts of the front and rear sides of the first sealing cover 1023.

[0036] In this embodiment, vibration frames 1032 are fixedly connected to the middle parts of the lower ends of the screening and conveying device 102 and the drying and conveying device 104.

Driving shafts 1031 are fixedly connected to the middle parts of the wind wheels 1030. Eccentric vibration wheels 1033 are fixedly connected to the front and rear ends of the driving shafts 1031.

[0037] Specifically, since the wind blades II 1048 on both sides continuously blow hot air into the interior of the hot steam recovery cover II 1037 to dry the camellia oil seeds, the dried hot steam will enter the steam spraying pipe 1022 in the sealing cover I 1023 through the connecting pipe I 1024 connected to the upper end of the hot steam recovery cover II 1037. The hot steam contained will be sprayed from the steam spraying pipe 1022 onto the camellia oil seeds passing through the lower end of the sealing cover I 1023 at the upper end of the screening and conveying device 102 to soften the stubborn stains on the surface of the camellia oil seeds. At the same time, most of the steam in the hot steam remains on the surface of the camellia oil seeds. Part of the hot steam is conveyed to the cleaning and conveying device 103 after passing through the screening and conveying device 102. The motor I 1026 below the sealing cover I 1023 drives the wind blade I 1027 to rotate, thereby collecting the hot steam passing through the screening and conveying device 102 and conveying it to the left wind bin 1029 through the connecting pipe II 1028. The wind wheel 1030 drives the drive shaft 1031 to rotate, thereby causing the eccentric vibration wheels 1033 on the front and rear sides to rotate eccentrically to generate centrifugal force, and applying the centrifugal force to the screening and conveying device 102 through the vibration frame 1032. With the cooperation of the buffer support rods 105 at the four corners of the lower end of the screening and conveying device 102, the screening and conveying device 102 vibrates, thereby causing the camellia oil seeds at the upper end of the screening and conveying device 102 to vibrate. When vibrating, the camellia oil seeds can be turned over, so that the entire surface of the camellia oil seeds will be softened by the hot steam. Furthermore, when the later water spraying pipe 1039 flushes tap water onto the camellia oil seeds, the stubborn stains can be more easily washed away from the surface of the camellia oil seeds, which is beneficial to the cleaning degree of the camellia oil seeds.

[0039] In this embodiment, heat steam recovery covers 1025 are fixedly connected to the lower ends of the screening and conveying device 102 and the cleaning and conveying device 103 respectively, which are located directly below the first sealing cover 1023 and the second sealing cover 1040. Motors 1026 are fixedly connected to the lower ends of the heat steam recovery covers 1025. Wind wheels 1027 are fixedly connected to the upper driving ends of the motors 1026. A second connecting pipe 1028 is fixedly connected to the lower left opening of the left end of the wind wheel 1027. The left end of the second connecting pipe 1028 is fixedly connected to the right end of the left wind chamber 1029. A third connecting pipe 1043 is arranged on the side where the two right heat steam recovery covers 1025 are close to each other, and both are communicated with the left end of the third connecting pipe 1043. The right end of the third connecting pipe 1043 is fixedly connected to the left end of the right wind chamber 1029. The right end of the right wind chamber 1029 is communicated with an exhaust pipe 1042, and the lower end of the exhaust pipe 1042 is communicated with the inside of the drying cover 1044.

[0040] Specifically, the hot steam inside the wind chamber 1029 is transported to the hot steam spraying pipe 1041 through the fourth connecting pipe 1050. When the washed camellia oil seeds pass by the lower end of the second sealing cover 1040, the washed camellia oil seeds can be preheated, realizing that the camellia oil seeds can be quickly dried during subsequent drying, which is beneficial to the production efficiency of camellia oil seed oil extraction.

[0041] In this embodiment, connecting frames 1015 are fixedly connected to the left ends of the front and rear sides of the screening and conveying device 102.

A first large gear 1011 is fixedly connected to the front end of the conveying roller 109. A first small gear 1012 is meshed and connected to the right side of the first large gear 1011. A kicking and selecting roller 1013 is fixedly connected to the middle of the first small gear 1012. Kicking and selecting belts 1014 are evenly distributed on the outer circumference of the kicking and selecting roller 1013. The front and rear ends of the kicking and selecting roller 1013 are rotatably connected to the upper openings of the connecting frames 1015.

[0042] In this embodiment, a first pulley 1034 is fixedly connected to the front end of the driving shaft 1031. The first pulley 1034 is connected to a second pulley 1036 through a transmission belt 1035. The middle of the second pulley 1036 is fixedly connected to the front end of the kicking and selecting roller 1013.

[0043] Specifically, when the drive shaft 1031 drives the eccentric vibration wheel 1033 to rotate, it synchronously drives the first pulley 1034 to rotate. Through the transmission belt 1035, it drives the kicking and selecting roller 1013 to rotate. Since the screening and conveying device 102 drives the camellia oil seeds to vibrate, and the immature or mildewed particles in the camellia oil seeds are lighter, these camellia oil seeds will be shaken higher and shaken out from the mature and normal camellia oil seeds. At this time, the kicking and selecting belts 1014 evenly distributed on the outer circumference of the kicking and selecting roller 1013 will kick out these immature or mildewed particles, which will fall into the interior of the arc-shaped conveying box 108 from the arc-shaped baffle at the upper end of the arc-shaped conveying box 108. At the same time, the first small gear 1012 drives the first large gear 1011 to rotate, and then drives the conveying auger 1010 to rotate through the conveying roller 109, and finally outputs these immature or mildewed particles from the arc-shaped conveying box 108. By being able to kick out the immature or mildewed particles inside the camellia oil seeds before hot steam softening, it realizes that there is no need to manually select the immature or mildewed particles in the camellia oil seeds before cleaning, saves labor costs, and avoids that some particles with no mildew on the surface but mildewed inside the shell are not selected during manual selection, improving the quality of subsequent oil pressing.

[0044] In this embodiment, a cam 1016 is fixedly connected to the rear end of the kicking and selecting roller 1013. A rack 1017 is attached to the right side of the cam 1016. A limiting frame 1018 is slidably connected to the outer circumference of the middle part of the rack 1017. A third small gear 1021 is meshed with the right end of the rack 1017. The inner circumference of the third small gear 1021 is fixedly connected to the outer circumference of the rear end of the steam spraying pipe 1022. A spring 1019 is sleeved on the left side of the middle part of the rack 1017. The left end of the spring 1019 is fixedly connected to a limiting plate 1020.

[0045] In this embodiment, the front side of the limiting frame 1018 is fixedly connected to the middle part of the rear end of the screening and conveying device 102. The inner circumference of the middle part of the limiting plate 1020 is fixedly connected to the outer circumference of the left side of the middle part of the rack 1017.

[0046] Specifically, when the kicking and selecting roller 1013 rotates to kick out the immature or mildewed particles in the camellia oil seeds, it synchronously drives the cam 1016 to rotate. Then, through the cooperation of the spring 1019, the limiting plate 1020 and the limiting frame 1018, it drives the rack 1017 to reciprocate and rub, and then drives the steam spraying pipe 1022 to rotate reciprocally through the third small gear 1021, and then evenly sprays the hot steam onto the upper end of the camellia oil seeds conveyed to the lower end of the first sealing cover 1023, realizing more evenly spraying the hot steam onto the surface of the camellia oil seeds, so that the stubborn stains on the surface of the camellia oil seeds can be softened more thoroughly.

[0047] Working principle: First, start the screening and conveying device 102, the cleaning and conveying device 103, and the drying and conveying device 104, and start the second motor 1045, the heating wire 1049, and the first motor 1026. Connect the water spray pipe 1039 to tap water. The second motor 1045 drives the second wind blade 1048 to rotate through the second large gear 1046 and the second small gear 1047 to preheat the internal area of the second hot steam recovery cover 1037 on both sides of the middle of the drying and conveying device 104. The camellia oil seeds are conveyed from the material conveyor belt to the inside of the feeding port 107 and evenly scattered to the upper left side of the screening and conveying device 102. They are conveyed to the right by the screening and conveying device 102 and fall to the upper end of the cleaning and conveying device 103, where they are cleaned by the tap water sprayed by the water spray pipe 1039. After cleaning, they are continuously conveyed to the right by the cleaning and conveying device 103 and fall to the upper end of the drying and conveying device 104, where they are dried when passing under the two second hot steam recovery covers 1037, completing the washing and drying of the camellia oil seeds. Since the second wind blades 1048 on both sides continuously blow hot air into the second hot steam recovery cover 1037 to dry the camellia oil seeds, the dried hot steam will enter the steam spray pipe 1022 in the first sealing cover 1023 through the first connecting pipe 1024 connected to the upper end of the second hot steam recovery cover 1037. The hot steam containing will be sprayed by the steam spray pipe 1022 onto the camellia oil seeds passing under the lower end of the first sealing cover 1023 on the upper end of the screening and conveying device 102 to soften the stubborn stains on the surface of the camellia oil seeds. At the same time, most of the steam in the hot steam is retained on the surface of the camellia oil seeds. Part of the hot steam is conveyed to the cleaning and conveying device 103 after passing through the screening and conveying device 102. The first motor 1026 under the first sealing cover 1023 drives the first wind blade 1027 to rotate, and then collects the hot steam passing through the screening and conveying device 102 and conveys it to the left air bin 1029 through the second connecting pipe 1028. The air wheel 1030 drives the drive shaft 1031 to rotate, and then the front and rear eccentric vibration wheels 1033 rotate eccentrically to generate centrifugal force, and the centrifugal force acts on the screening and conveying device 102 through the vibration frame 1032. With the cooperation of the buffer support rods 105 at the four corners of the lower end of the screening and conveying device 102, the screening and conveying device 102 vibrates, and then the camellia oil seeds on the upper end of the screening and conveying device 102 vibrate. When vibrating, the camellia oil seeds can be turned over, so that the entire surface of the camellia oil seeds will be softened by the hot steam, and then when the water spray pipe 1039 flushes the camellia oil seeds with tap water later, the stubborn stains can be more easily washed away from the surface of the camellia oil seeds, which is beneficial to the cleaning degree of the camellia oil seeds. When the drive shaft 1031 drives the eccentric vibration wheel 1033 to rotate, it synchronously drives the first pulley 1034 to rotate, and drives the kicking and selecting roller 1013 to rotate through the transmission belt 1035. Since the screening and conveying device 102 drives the camellia oil seeds to vibrate, and the immature or mildewed particles in the camellia oil seeds are lighter, so these camellia oil seeds will be shaken higher and shaken out from the mature and normal camellia oil seeds. At this time,The screening belt 1014 evenly distributed on the outer periphery of the screening roller 1013 will kick out these immature or mildewed particles, which will fall from the arc-shaped baffle at the upper end of the arc-shaped conveying box 108 into the interior of the arc-shaped conveying box 108. At the same time, the first small gear 1012 drives the first large gear 1011 to rotate, and then drives the conveying auger 1010 to rotate through the conveying roller 109, and finally outputs these immature or mildewed particles from the arc-shaped conveying box 108. By kicking out the immature or mildewed particles inside the camellia oil seeds before the hot steam softening, it realizes that there is no need to manually select the immature or mildewed particles in the camellia oil seeds before cleaning, saves labor costs, and avoids the situation that some particles with no visible mildew on the surface but mildewed inside the shell are not selected during manual selection, improving the quality of subsequent oil extraction. When the screening roller 1013 rotates to screen the immature or mildewed particles in the camellia oil seeds, it synchronously drives the cam 1016 to rotate. Then, through the cooperation of the spring 1019, the limit plate 1020 and the limit frame 1018, it drives the rack 1017 to reciprocate and rub, and then drives the steam spraying pipe 1022 to rotate reciprocally through the third small gear 1021, and then evenly sprays the hot steam onto the upper end of the camellia oil seeds conveyed to the lower end of the first sealing cover 1023, realizing more uniform spraying of the hot steam onto the surface of the camellia oil seeds, so that the stubborn stains on the surface of the camellia oil seeds can be softened more thoroughly. The hot steam in the air chamber 1029 is conveyed into the hot steam spraying pipe 1041 through the fourth connecting pipe 1050. When the washed camellia oil seeds pass by the lower end of the second sealing cover 1040, it can preheat the washed camellia oil seeds, realizing that during subsequent drying, the camellia oil seeds can be quickly dried, which is beneficial to the production efficiency of camellia oil seed oil extraction. After being cooled by the hot steam on the upper right side of the cleaning and conveying device 103, it is collected by the first hot steam recovery cover 1025 at the lower end, and through the rotation of the first air blade 1027 inside, it is sent into the air chamber 1029 in the middle of the lower end of the drying and conveying device 104 through the third connecting pipe 1043. Similarly, it drives the drying and conveying device 104 to vibrate slightly, making the drying more thorough during the drying process, and the remaining air volume is sent back into the two third connecting pipes 1043 through the exhaust pipe 1042, mixing with the air entering the interior of the third connecting pipe 1043, so that the air entering the third connecting pipe 1043 can be preheated. After the equipment runs for a period of time, the heat generation of the heating wire 1049 can be appropriately reduced, thereby realizing energy saving and prolonging the service life of the heating wire 1049.
