Description

Technical Field

[0001] This invention belongs to the technical field of areca nut roasting equipment, specifically an areca nut roasting production equipment. Background Technology

[0002] Areca nut is one of the four major southern Chinese medicinal herbs, belonging to the palm family and being an evergreen tree. The fruit of the areca nut is called areca nut, and it contains arecoline and tannic acid, among other things. The use of areca nut includes chewing and refining for medicinal extraction. Fresh areca nut has a short shelf life and is not suitable for long-distance transportation for sale. Further processing of areca nut into dried product, along with seasonings, makes it easier to store. The processing method mainly involves steaming followed by drying. Currently, the main method for drying areca nut is to transport the boiled areca nut to a drying room for roasting. During the roasting process, the areca nut needs to be turned over to ensure even roasting.

[0003] In existing areca nut roasting equipment, due to the irregular shape of areca nuts, roasting and conveying are separated into two devices. During roasting, they are either roasted together separately, which can easily lead to uneven roasting due to the accumulation of areca nuts, or they are roasted one by one, which is time-consuming and labor-intensive. This not only increases the equipment's footprint but also reduces roasting efficiency.

[0004] Therefore, the present invention provides a betel nut roasting production equipment. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is: the areca nut roasting production equipment of the present invention includes a roasting box, a turning mechanism and a conveying mechanism, wherein the conveying mechanism is located at the bottom of the roasting box and the turning mechanism is located inside the roasting box;

[0007] The bottom of the baking oven is equipped with a base, and dust-proof curtains are installed at both ends of the baking oven.

[0008] The transmission mechanism includes multiple first-order transmission components;

[0009] The roasting oven is used to roast areca nuts, removing their internal moisture. The turning mechanism rotates and flips the areca nuts during the roasting process, ensuring they are roasted from all sides. The conveying mechanism moves the areca nuts and removes any substandard nuts and impurities during the process. In operation, the areca nuts are first placed on the surface of each first-stage conveyor, and then conveyed into the roasting machine for roasting. Dust curtains are installed at both ends of the roasting machine to prevent dust from entering during the process. The roasting oven effectively removes the internal moisture of the areca nuts, increasing their shelf life.

[0010] Preferably, the flipping mechanism includes a sliding block fixedly connected to the bottom of the first-stage conveyor, a flipping element slidably connected to the outer wall of the sliding block, a sliding groove formed inside the flipping element, the outer wall of the sliding block slidably connected to the inside of the sliding groove, and flipping toothed rings symmetrically mounted on the outer wall of the flipping element, with the teeth of two adjacent flipping toothed rings meshing with each other. The flipping mechanism also includes a fixed block installed inside the base, a rotating column rotatably connected between the outer walls of the fixed block, a main control unit fixedly connected to the outer wall of the rotating column, the teeth of the main control unit meshing with the teeth of one of the flipping toothed rings, and the rotating column... One end of the device is fixedly connected to a lifting wheel, and a lifting belt is drivenly connected to the outer wall of the lifting wheel. A telescopic cylinder is installed in a slot in the base. A reversing column is fixedly installed on the outer wall of the base, and a lifting component is rotatably connected to the outer wall of the reversing column. Displacement columns are fixedly connected to the inner walls of both sides of the lifting component. An arc-shaped groove is formed on the outer wall of the base, and the outer wall of one end of the displacement column is slidably connected to the inner wall of the arc-shaped groove. The output shaft of the telescopic cylinder is fixedly connected to the outer wall of the lifting component. One end of the lifting belt is fixedly connected to the outer wall of one of the displacement columns, and the other end of the lifting belt is fixedly connected to the outer wall of the other displacement column. When one... When the conveyor moves the areca nuts into the roasting oven, the telescopic cylinder is activated first. The output shaft of the telescopic cylinder controls one end of the lifting and lowering component to repeatedly rise and fall. The lifting and lowering component will control the displacement column to slide back and forth inside the arc-shaped groove with the reversing column as the center. At the same time, the two ends of the lifting and lowering component control the lifting wheels to repeatedly rotate left and right via the lifting belt. The rotation angle of the lifting wheels is controlled to be less than 90 degrees. As the lifting wheels are controlled, the main control also rotates. Because the main control is engaged with the flipping tooth ring on the outer wall of the flipping component, the first flipping component is also controlled to rotate with the main control as the main control rotates left and right. The control rotates in opposite directions, and due to the meshing of the teeth between two adjacent flipping parts, all flipping parts will rotate in different directions. Since the first-stage conveyor and the flipping parts are connected by sliding blocks in the groove, when the flipping parts rotate, the first-stage flipping parts will slide inside the first-stage conveyor along the trajectory of the groove. At this time, the areca nuts on the first-stage conveyor will flip and roll on its surface. Therefore, each areca nut entering the baking oven is fully heated and baked. Through the cooperation between the flipping parts and the first-stage conveyor, each areca nut can be fully baked.

[0011] Preferably, the conveying mechanism further includes multiple screening components installed inside the baking oven. Each screening component has several slag removal ports on its outer wall. A power gear ring is installed at one end of each screening component, and the power gear ring is rotatably connected to a second-stage conveyor. The upper surface of the second-stage conveyor is located below the lower surface of the first-stage conveyor. The teeth of one of the power gear rings mesh with the teeth of the main control unit, and the teeth of two adjacent power gear rings mesh with each other. A third-stage conveyor is installed inside the baking oven, and the upper surface of the third-stage conveyor is rotatably connected to the outer wall of the screening components. A slag removal plate is installed at the bottom of each screening component. The heights of the first-stage, second-stage, and third-stage conveyors decrease sequentially downwards. While the areca nuts are being roasted on the first-stage conveyor, the power gear ring rotates left and right due to its meshing with the main control unit. The power gear controls the rotation of the screening unit, and due to the meshing of two adjacent power gears, each screening unit performs the same movement as the first-stage conveyor. After the areca nuts are conveyed from the first-stage conveyor to the second-stage conveyor, they are then conveyed into the interior of the screening unit. At this point, some substandard areca nuts with non-compliant shapes and other impurities will fall down to the impurity removal plate through the slag removal port of the screening unit, while relatively high-quality areca nuts will slide down the screening unit to the third-stage conveyor. Through the above structure, the inferior areca nuts and impurities mixed in with the areca nuts are effectively screened out.

[0012] Preferably, a waste gas treatment box is placed at the bottom of the base, and a waste material treatment box is installed at the bottom of the base and adjacent to the waste gas treatment box. An exhaust vent is provided at the top of the baking oven. A ventilation component is installed at the top of the baking oven above the exhaust vent, and an exhaust pipe is installed at the top of the ventilation component. The other end of the exhaust pipe is fixedly connected to the outer wall of the waste gas treatment box. An exhaust fan and a dust removal plate are installed inside the ventilation component, with the dust removal plate located above the exhaust fan. The opening of the waste material treatment box is located directly above the other end of the dust removal plate. Below, a waste collection cylinder is installed inside the waste treatment box. A sliding chute is installed on the outer wall of the waste collection cylinder. Fallen impurities will be conveyed by the impurity removal plate and fall into the waste collection cylinder, and finally slide down along the sliding chute. The roasted areca nuts will be conveyed to the outside of the roasting box by a three-stage conveyor and finally collected and processed. Some waste gas is generated during the roasting process of areca nuts. If this waste gas is released into the air, it will pollute the air in the area. Therefore, these gases are recovered and processed by a ventilation device. Through the above structure, the high-quality areca nuts are effectively separated from the inferior ones.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. The areca nut roasting production equipment of the present invention, through the cooperation of the flipping component and the first-stage conveyor, achieves the effect of ensuring that each areca nut is fully roasted. The first flipping component is controlled to rotate in the opposite direction to the main control component. Due to the meshing of the teeth between two adjacent flipping components, all flipping components will rotate in different directions. Since the first-stage conveyor and the flipping component are connected by a sliding block in the slide groove, when the flipping component rotates, the first-stage flipping component will slide inside the first-stage conveyor according to the trajectory of the slide groove. At this time, the areca nuts on the first-stage conveyor will be flipped and rolled on its surface. Therefore, each areca nut entering the roasting box is fully heated and roasted.

[0015] 2. The areca nut roasting production equipment of the present invention, through the cooperation of the screening element and the power gear ring, achieves the effect of screening out inferior areca nuts and impurities mixed in with the areca nuts. When the areca nuts are roasted on the first-stage conveyor, the power gear ring also rotates left and right due to the meshing with the main control unit. The power gear controls the rotation of the screening element. Due to the meshing of two adjacent power gears, each screening element performs the same movement as the first-stage conveyor. When the areca nuts are conveyed to the second-stage conveyor through the first-stage conveyor, they are then conveyed to the inside of the screening element. At this time, some substandard areca nuts with non-compliant shapes and some other impurities will fall down to the impurity removal plate through the slag removal port of the screening element, while the relatively high-quality areca nuts will slide down the screening element to the third-stage conveyor.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figures 1 to 2 As shown, an embodiment of the present invention provides a betel nut roasting production equipment, which includes a roasting box 1, a turning mechanism 100, and a conveying mechanism 200. The conveying mechanism 200 is located at the bottom of the roasting box 1, and the turning mechanism 100 is located inside the roasting box 1.

[0030] A base 11 is installed at the bottom of the baking oven 1, and dust curtains 12 are installed at both ends of the baking oven 1.

[0031] The transmission mechanism 200 includes multiple first-order transmission components 201;

[0032] During operation, the roasting oven 1 is used to roast the areca nuts, removing their internal moisture. The turning mechanism 100 rotates and turns the areca nuts during the roasting process, ensuring they are roasted from all sides. The conveying mechanism 200 moves the areca nuts and removes some of the inferior areca nuts and impurities during the movement. In operation, the areca nuts are first placed on the surface of each first-stage conveyor 201, and then conveyed into the roasting machine for roasting. Dust curtains 12 are installed at both ends of the roasting machine to prevent dust from entering during the production process. The roasting of the areca nuts by the roasting oven 1 effectively removes the internal moisture of the areca nuts, increasing their shelf life.

[0033] like Figures 2 to 6 As shown, the flipping mechanism 100 includes a sliding block 101 fixedly connected to the bottom of the first-stage conveyor 201. A flipping member 102 is slidably connected to the outer wall of the sliding block 101. A groove 103 is provided inside the flipping member 102. The outer wall of the sliding block 101 is slidably connected to the inside of the groove 103. Flipping toothed rings 104 are symmetrically installed on the outer wall of the flipping member 102. The teeth of two adjacent flipping toothed rings 104 mesh with each other. The flipping mechanism 100 also includes a fixing block 105 installed inside the base 11. A rotating column 106 is rotatably connected between the outer walls of the fixing block 105. A main control unit 107 is fixedly connected to the outer wall of the rotating column 106. The teeth mesh with the teeth of one of the rotating toothed rings 104. One end of the rotating column 106 is fixedly connected to the lifting wheel 108. The outer wall of the lifting wheel 108 is connected to the lifting belt 109. The slot of the base 11 is equipped with a telescopic cylinder 110. The outer wall of the base 11 is fixedly installed with a reversing column 111. The outer wall of the reversing column 111 is rotatably connected to the lifting component 112. The inner walls of both sides of the lifting component 112 are fixedly connected with displacement columns 113. The outer wall of the base 11 is provided with an arc-shaped groove 114. One end of the outer wall of the displacement column 113 is slidably connected to the inner wall of the arc-shaped groove 114. The output shaft of the telescopic cylinder 110 is fixedly connected to the outer wall of the lifting component 112.

[0034] One end of the lifting belt 109 is fixedly connected to the outer wall of one of the displacement columns 113, and the other end of the lifting belt 109 is fixedly connected to the outer wall of the other displacement column 113.

[0035] During operation, when the first-stage conveyor 201 moves the areca nuts into the roasting oven 1, the telescopic cylinder 110 is activated first. The output shaft of the telescopic cylinder 110 controls one end of the lifting and lowering component 112 to repeatedly rise and fall. The lifting and lowering component 112 will control the displacement column 113 to slide back and forth inside the arc-shaped groove 114 with the reversing column 111 as the center. At the same time, the two ends of the lifting and lowering component 112 control the lifting wheel 108 to repeatedly rotate left and right through the lifting belt 109. The rotation angle of the lifting wheel 108 is controlled to be less than 90 degrees. As the lifting wheel 108 is controlled, the main control unit 107 also rotates. Because the main control unit 107 meshes with the reversing toothed ring 104 on the outer wall of the flipping component 102, the first flipping component 102 rotates left and right simultaneously. 02 is also controlled to rotate in the opposite direction to the main control 107. Due to the meshing of the teeth between two adjacent flipping parts 102, all flipping parts 102 will rotate in different directions. Since the first-stage conveyor 201 and the flipping parts 102 are connected by the sliding block 101 in the slide groove 103, when the flipping parts 102 rotate, the first-stage flipping parts 102 will slide inside the first-stage conveyor 201 along the trajectory of the slide groove 103. At this time, the areca nuts on the first-stage conveyor 201 will flip and roll on their surface. Therefore, each areca nut entering the baking oven 1 is fully heated and baked. Through the cooperation between the flipping parts 102 and the first-stage conveyor 201, each areca nut can be fully baked.

[0036] like Figures 5 to 8 As shown, the conveying mechanism 200 also includes multiple screening components 202 installed inside the baking oven 1. The outer wall of the screening component 202 has several slag removal ports 203. A power gear ring 204 is installed at one end of the screening component 202. The power gear ring 204 is rotatably connected to a second-stage conveyor 205. The upper surface of the second-stage conveyor 205 is located below the lower surface of the first-stage conveyor 201. The teeth of one of the power gear rings 204 mesh with the teeth of the main control 107. The teeth of two adjacent power gear rings 204 mesh with each other. A third-stage conveyor 206 is installed inside the baking oven 1. The upper surface of the third-stage conveyor 206 is rotatably connected to the outer wall of the screening component 202. A slag removal plate 207 is installed at the bottom of the screening component 202. The heights of the first-stage conveyor 201, the second-stage conveyor 205, and the third-stage conveyor 206 decrease sequentially.

[0037] During operation, while the areca nuts are being roasted on the first-stage conveyor 201, the power gear ring 204 rotates left and right due to its meshing with the main control unit 107. The power gear controls the rotation of the screening piece 202. Due to the meshing of two adjacent power gears, each screening piece 202 performs the same movement as the first-stage conveyor 201. After the areca nuts are conveyed from the first-stage conveyor 201 to the second-stage conveyor 205, they are then conveyed by the second-stage conveyor 205 into the interior of the screening piece 202. At this time, some substandard areca nuts with non-compliant shapes and other impurities will fall down through the slag removal port 203 of the screening piece 202 onto the impurity removal plate 207, while relatively high-quality areca nuts will slide along the screening piece 202 onto the third-stage conveyor 206. Through the above structure, the effect of screening out substandard areca nuts and impurities mixed in with the areca nuts is achieved.

[0038] like Figure 1 and Figure 10 As shown, a waste gas treatment box 13 is placed at the bottom of the base 11, and a waste material treatment box 14 is installed at the bottom of the base 11 and adjacent to the waste gas treatment box 13. An exhaust port 15 is opened at the top of the baking oven 1. An air exchange component 16 is installed at the top of the baking oven 1 and above the exhaust port 15. An exhaust pipe 17 is installed at the top of the air exchange component 16. The other end of the exhaust pipe 17 is fixedly connected to the outer wall of the waste gas treatment box 13. An air exchange fan 18 and a dust removal plate 19 are installed inside the air exchange component 16. The dust removal plate 19 is located above the air exchange fan 18. The opening of the waste material treatment box 14 is located directly below the other end of the dust removal plate 207.

[0039] The waste disposal box 14 is equipped with a waste collection cylinder 20, and the outer wall of the waste collection cylinder 20 is equipped with a material sliding groove 21.

[0040] During operation, falling impurities are conveyed by the impurity removal plate 207 into the waste collection cylinder 20, and finally slide down the material chute 21. The roasted areca nuts are then conveyed by the three-stage conveyor 206 to the outside of the roasting chamber 1 and finally collected and processed. During the roasting process of areca nuts, some waste gas is generated. If this waste gas is released into the air, it will pollute the air in the area. Therefore, the gas is recycled and processed by the ventilation device 16. Through the above structure, the high-quality areca nuts are separated from the inferior ones.

[0041] Working principle: The roasting oven 1 is used to roast the areca nuts, removing their internal moisture. The turning mechanism 100 rotates and turns the areca nuts during the roasting process, ensuring they are roasted from all sides. The conveying mechanism 200 moves the areca nuts and removes some of the inferior areca nuts and impurities during the movement. In operation, the areca nuts are first placed on the surface of each first-stage conveyor 201, and then conveyed into the roasting machine for roasting. Dust curtains 12 are installed at both ends of the roasting machine to prevent dust from entering during the process. When the first-stage conveyor 201 moves the areca nuts into the roasting oven 1, the telescopic cylinder 110 is activated. The output shaft of the telescopic cylinder 110 controls the lifting mechanism 112. The lifting and lowering component 112 repeatedly raises and lowers, controlling the displacement column 113 to slide back and forth inside the arc-shaped groove 114 with the reversing column 111 as the center. Simultaneously, the lifting wheels 108 at both ends of the lifting component 112 are controlled by the lifting belt 109 to repeatedly rotate left and right. The rotation angle of the lifting wheels 108 is controlled to be less than 90 degrees. As the lifting wheels 108 are controlled, the main control unit 107 also rotates. Because the main control unit 107 meshes with the reversing toothed ring 104 on the outer wall of the reversing component 102, while the main control unit 107 rotates left and right, the first reversing component 102 is also controlled to rotate in the opposite direction to the main control unit 107. Furthermore, due to the meshing of the teeth between adjacent reversing components 102, all reversing components 102... Both will rotate in different directions. Because the first-stage conveyor 201 and the flipping component 102 are connected by the sliding block 101 sliding in the groove 103, when the flipping component 102 rotates, the first-stage flipping component 102 will slide inside the first-stage conveyor 201 along the trajectory of the groove 103. At this time, the areca nuts on the first-stage conveyor 201 will flip and roll on their surface. Therefore, each areca nut entering the baking oven 1 is fully heated and baked. While the areca nuts are baked on the first-stage conveyor 201, the power gear ring 204 also rotates left and right due to its meshing with the main control 107. The power gear controls the screening component 202 to rotate. Due to the meshing of two adjacent power gears, each screening component 202... All components undergo the same motion as the first-stage conveyor 201. After the areca nuts are conveyed from the first-stage conveyor 201 to the second-stage conveyor 205, they are then conveyed by the second-stage conveyor 205 into the screening section 202. At this point, some substandard areca nuts with non-compliant shapes and other impurities will fall down through the slag removal port 203 of the screening section 202 onto the impurity removal plate 207. Relatively high-quality areca nuts will slide down the screening section 202 onto the third-stage conveyor 206. The fallen impurities will be conveyed by the impurity removal plate 207 into the waste collection cylinder 20, and finally slide down along the material chute 21. The roasted areca nuts will then be conveyed by the third-stage conveyor 206 to the outside of the roasting chamber 1 for collection and processing. Some waste gas will be generated during the areca nut roasting process.If these exhaust gases were to circulate into the air, they would pollute the air in the area. Therefore, the ventilation unit 16 is used to recover and treat these gases.
