Description

Technical Field

[0001] The invention relates to the technical field of dehydration and drying, in particular to a potato dehydration and drying device with a grid self-cleaning function. Background Art

[0002] The scientific name for the sweet potato is Ipomoea batatas, also known as sweet potato, yam, and yam. Sweet potatoes boast high yields, a wide range of uses, and strong adaptability. They contain a variety of nutrients, including starch, sugars, protein, vitamins, cellulose, and various amino acids, making them a highly nutritious food. They are a key food crop in my country, with the world's largest cultivated area. The various vitamins and amino acids in sweet potatoes have preventative and therapeutic effects on certain human diseases, and some can even prevent cancer. In recent years, with the growing awareness of health preservation, the role of the sweet potato in the food chain has evolved.

[0003] In the prior art, sweet potato strips or slices are typically placed on drying trays to dry in the sun. After removing a certain amount of moisture, the sweet potato strips or slices are then placed in a drying room for baking. However, due to high production volumes, the sweet potato strips or slices are often stacked together for drying, which takes a long time. This stacking of sweet potato strips or slices frequently requires removing the drying trays from the drying room and manually shaking and turning the sweet potato strips or slices. This current drying method requires a long drying time, which is not conducive to improving production efficiency. Summary of the Invention

[0004] The object of the present invention is to provide a potato dehydration and drying device with a self-cleaning function of the grid, so as to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a potato dehydration and drying device with a self-cleaning function of a grid, the dehydration and drying device comprising a bracket, a drain box and a drying box, the drain box and the drying box are both mounted on the bracket, and the drying box is located below the drain box;

[0006] A grid and a gallows are installed in the drain box, the gallows is installed in the grid, a driving motor is installed below the drain box, the driving motor is meshed with the grid for transmission, a lower ratchet is installed on the outer side of the lower end of the gallows, the outer ring of the lower ratchet is meshed with the grid for transmission, an upper ratchet is installed in the middle of the upper end of the gallows, and the upper ratchet is connected to the drain box;

[0007] A discharge belt is installed at the lower end of the drainage tank. One end of the discharge belt is located below the wire rack, and the other end of the discharge belt is located above the drying box. The upper ratchet wheel and the lower ratchet wheel rotate in opposite directions. When the lower ratchet wheel drives, the upper ratchet wheel idles. When the lower ratchet wheel idles, the upper ratchet wheel drives. The wire rack is cylindrical, and a number of water drainage holes are provided on the cylinder body. The raw materials in slices / strips enter the wire rack through the hopper above the drainage tank and fall above the cross frame. When the driving motor works under the control of the control system and drives the wire rack to rotate forward through the gear, the wire rack drives the cross frame to rotate together through the lower ratchet wheel. At this time, the upper ratchet wheel is in an idling state. When the driving motor drives the wire rack to rotate reversely, the wire rack rotates independently in the drainage tank. At this time, the lower ratchet wheel is in an idling state, and the upper ratchet wheel drives normally and prevents the cross frame from following the wire rack to rotate. A scraper is installed at the upper end inside the drainage tank through a bracket, and the lower end of the scraper is in sliding contact with the upper end of the cross frame. When the wire rack and the cross frame rotate together, the raw materials above the cross frame fit against the inner wall of the wire rack under the action of centrifugal force. During the rotation of the wire rack and the cross frame, the scraper pushes the raw materials into the spiral part of the cross frame, and the cross frame transports the raw materials to the bottom of the drainage tank through the spiral part. During the process of the raw materials falling to the bottom of the wire rack, the raw materials are centrifugally dehydrated. The dehydrated raw materials are pushed by the cross frame onto the discharge belt. The discharge belt is a conveyor belt, and the discharge belt sends the dehydrated raw materials into the drying box, and the drying box dries the raw materials.

[0008] A backing plate and a cushion block are installed inside the box body of the drainage tank. A support cylinder is installed outside the backing plate. The cushion block is located at the center of the backing plate, and a bearing plate is installed on the cushion block. A sector-shaped notch is provided on the cushion block and the bearing plate. The driving motor is located on one side of the cushion block. One end of the discharge belt is located in the sector-shaped notch. The discharge belt penetrates through the support cylinder and the box body. The cross frame is rotatably installed on the bearing plate;

[0009] A guide ring is installed on the outer side of the lower end of the wire rack. The upper end surface of the guide ring is a slope, and a dehydration groove is provided at the lowest point of the upper end surface of the guide ring. A water outlet pipe is installed below the box body. A gear ring is installed at the lower end of the wire rack. The lower end of the gear ring is rotatably connected to the support cylinder. The output end of the driving motor is installed with a main gear, and the main gear is meshed with the gear ring for driving. The sector-shaped notch on the bearing plate is used for feeding, and the sector-shaped notch on the cushion block is used for installing the discharge belt. The support cylinder supports the wire rack and intercepts the water drained from the raw materials at the same time to prevent the water from contacting the driving motor and the discharge belt. The drained water slides down through the guide ring between the box body and the support cylinder and flows out of the box body through the water outlet pipe.

[0010] The cross frame includes an upper end plate, a spiral plate and a central shaft. The central shaft is fixed in the middle of the spiral plate. The central shaft penetrates through the middle of the upper end plate. A sector-shaped material opening is provided on the upper end plate. The upper end of the spiral plate is connected to the position of the sector-shaped material opening. The upper ratchet wheel is installed at the upper end of the central shaft, and the outer ring of the upper ratchet wheel is connected to the box body;

[0011] Four stirring shafts are annularly installed on the spiral plate. The cross-section of the stirring shaft is a right triangle. The surface where the hypotenuse of the stirring shaft is located fits against the inner wall of the grid. The surface where the long right-angled side of the stirring shaft is located is provided with corrugated grooves. The lower ends of the four stirring shafts are jointly installed with a driven ring. The driven ring is located outside the bearing plate, and the lower ratchet is installed outside the driven ring. When the driving motor drives the gear ring to rotate, the grid rotates together. When dehydrating the raw materials, the driving motor drives the grid to rotate forward. The lower ratchet drives the spiral plate and the upper end plate to rotate together through the driven ring and the stirring shaft. The raw materials continuously approach the edge of the upper end plate and the inner wall of the grid under the centrifugal force, and the raw materials are dehydrated under the centrifugal force. When the raw materials are at the edge of the upper end plate and the inner wall of the grid, the scraper intercepts the raw materials on the upper end plate and pushes the raw materials from the fan-shaped material outlet onto the spiral plate. The continuous rotation of the spiral plate makes the raw materials move downward while being subjected to the centrifugal force. During the rotation of the spiral plate, the stirring shaft uses the corrugated grooves to stir the raw materials, causing the raw materials to tumble in the grid. After the raw materials fall on the bearing plate, during the rotation of the spiral plate, the lower end of the spiral plate pushes the raw materials to the fan-shaped notch, so that the raw materials fall from the fan-shaped notch onto the discharge belt, thus realizing the automatic discharge of the raw materials after dehydration. After the raw materials are dehydrated in the grid, in order to clean the raw materials attached to the inner wall of the grid, the grid needs to be cleaned. When cleaning the grid, the driving motor drives the grid to rotate in reverse. When the grid rotates in reverse, the upper ratchet at the upper end of the central shaft limits the position of the entire winch. The lower ratchet idles with the gear ring. The grid rotates in reverse and has a relative movement with the winch. At this time, the stirring shaft cleans the inner wall of the grid when the grid rotates, scraping off the residual raw materials on the inner wall, realizing the cleaning of the inner wall of the grid. After that, the driving motor drives the grid to rotate forward again, and the residual raw materials on the spiral plate are sent out of the drainage tank by the spiral plate.

[0012] A number of connecting plates are arranged on the surface where the short right-angled side of each stirring shaft is located. One end of the connecting plate is installed with a hemispherical cleaning hammer. The position where the cleaning hammer is located corresponds to the position of the drainage holes on the grid. The hemispherical cleaning hammer is located in the drainage holes, and the diameter of the cleaning hammer is smaller than the aperture of the drainage holes. When relative movement occurs between the stirring shaft and the grid, the hemispherical cleaning hammer is forced to slide out of the drainage holes, and the connecting plate also bends accordingly. When the cleaning hammer encounters the next drainage hole, the cleaning hammer is quickly pressed into the drainage hole under the support of the connecting plate, realizing the impact on the residual raw materials in the drainage holes and flushing the raw materials in the drainage holes out of the drainage holes. After that, under the support of the rotation of the grid, the cleaning hammer slides out of the drainage holes again and moves in the direction of the next drainage hole. During the rotation of the grid, the cleaning hammer is pressed into the drainage holes again and again and slides out of the drainage holes again and again, thereby realizing the cleaning of the drainage holes of the grid and improving the cleaning effect of the grid.

[0013] The drying oven includes a main body, and two main shafts are fixedly installed at the middle position of the main body. One end of the two main shafts facing each other is provided with a support plate, and two drying shafts are installed between the two support plates. The drying shafts are connected to a control system;

[0014] A sleeve plate is sleeved on the main shaft, and four drying mesh cylinders are rotatably installed between the two sleeve plates. The drying mesh cylinders are provided with feed ports. A feed hopper is installed above the main body. One end of the discharge belt is located above the feed hopper. A cylinder cover is rotatably installed on one side of the main body. The outer side of the cylinder cover is connected to a driving cylinder, and the other end of the driving cylinder is rotatably installed on a bracket;

[0015] A drying motor is installed on one side of the main body. The output shaft of the drying motor penetrates the main body and is installed with a driving gear. The driving gear meshes and drives with a driven gear ring on the sleeve plate. Outer gear rings are installed inside the main body at positions corresponding to both ends of the drying mesh cylinders. Gear grooves are formed at both ends of the drying mesh cylinders. The outer gear rings are meshed and driven with the drying mesh cylinders through the gear grooves. A coil is wound inside the drying shaft, and the coil is connected to the control system. The air in the main body is heated by resistance heat to realize the drying of the raw materials in the drying mesh cylinders. The sleeve plate is sleeved on the main shaft. A flange is installed on one side of the sleeve plate, and a gear groove is formed on the outer side of the flange for meshing and driving with the driving gear. The drying motor drives the driving gear to rotate. When the driving gear rotates, the sleeve plate rotates on the main shaft, and then the sleeve plate drives the four drying mesh cylinders to rotate. While the drying mesh cylinders rotate around the main shaft, they are also meshed and driven with the outer gear rings to realize self-rotation. The drying mesh cylinders continuously revolve around the main shaft and also rotate around their own central axes. Through the revolution and self-rotation of the drying mesh cylinders, the raw materials in the drying mesh cylinders are continuously turned over, so that the raw materials can be evenly heated. When discharging is required, the driving cylinder works under the control of the control system. The piston rod of the driving cylinder contracts, causing the cylinder cover to rotate on the main body, opening the discharge through groove on the main body. The dried raw materials flow out of the drying mesh cylinders and flow into the next process through the discharge through groove.

[0016] The drying mesh cylinder includes two driving plates and a number of flow stirring vanes. Gear grooves are provided on the annular side surfaces of the driving plates. Driving discs are installed on the outer end faces of the driving plates. The output ends of the driving discs are fixed to the sleeve plates. In the middle of the inner end faces of the driving plates, rotating discs are installed. The output ends of the rotating discs are equipped with driven plates. A number of arc-shaped grooves are formed in the driving plates. Two pin shafts are installed at both ends of each flow stirring vane. One pin shaft is rotatably installed on the driven plate, and the other pin shaft is slidably installed in the arc-shaped groove. Both the driving disc and the rotating disc are electric rotating discs and are connected to the control system. The driving disc is used to drive the drying mesh cylinder to rotate on the sleeve plate. When the raw materials are not dried and there is no need for discharging, the driving disc is not powered on and will not be self-locked, so that the drying mesh cylinder can rotate self in the main body. When the drying mesh cylinder rotates self, it rotates forward. The raw materials flow between a number of flow stirring vanes and will not flow out of the drying mesh cylinder. When discharging is required, after the cylinder cover is opened, the external gear ring with an arc degree of 1 / 2π rotates together with the cylinder cover, making the drying mesh cylinder that needs to discharge unable to drive with the external gear ring. At this time, the driving disc drives the drying mesh cylinder to rotate in reverse, so that the raw materials in the drying mesh cylinder flow out between a number of flow stirring vanes and flow out of the main body through the discharge through groove. The rotating disc makes the driven plate rotate on the driving plate, and then changes the state of the flow stirring vanes, making the gap between adjacent two flow stirring vanes smaller or making the gap between adjacent two flow stirring vanes larger. When the dehydrated raw materials enter the feed hopper, the rotating disc makes the gap between adjacent two flow stirring vanes larger. When the drying mesh cylinder passes through the feed hopper, the raw materials enter the interior of the drying mesh cylinder through the gaps between the flow stirring vanes. Moreover, because the drying mesh cylinder rotates self, the raw materials will only move from one flow stirring vane to the next flow stirring vane and will not directly flow out of the drying mesh cylinder. After the loading of the raw materials is completed, the rotating disc makes the driven plate rotate on the driving plate again, making the gap between the two flow stirring vanes smaller. During the rotation of the drying mesh cylinder, the flow stirring vanes press the hot air in the main body into the interior of the drying mesh cylinder, making the hot air flow in the drying mesh cylinder, thereby accelerating the drying efficiency of the raw materials. When the drying mesh cylinder discharges materials, the driving disc makes the drying mesh cylinder rotate in reverse, and at the same time the rotating disc makes the gap between adjacent two flow stirring vanes larger, so that the raw materials flow out of the drying mesh cylinder. After the raw materials are discharged, the driving disc is powered off and the cylinder cover is closed again, and the gap between adjacent two flow stirring vanes remains until the next addition of raw materials is completed.

[0017] The external gear ring is composed of two sections of gear rings. The arc degree of one section of the gear ring is 3 / 2π, and the arc degree of the other section of the gear ring is 1 / 2π. The gear ring with an arc degree of 3 / 2π is installed on the main body, and the gear ring with an arc degree of 1 / 2π is installed on the cylinder cover.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0019] 1. The driving motor drives the grid frame to reverse. When the grid frame reverses, the upper ratchet wheel at the upper end of the central shaft restricts the position of the entire winch, and the lower ratchet wheel idles with the gear ring. The grid frame reverses and has relative movement with the winch. At this time, the stirring shaft cleans the inner wall of the grid frame when the grid frame rotates, scraping off the residual raw materials on the inner wall to achieve cleaning of the inner wall of the grid frame. After that, the driving motor drives the grid frame to rotate forward again, and the residual raw materials falling on the spiral plate are sent out of the water drainage tank by the spiral plate.

[0020] When relative movement occurs between the stirring shaft and the grid frame, the hemispherical cleaning hammer is forced to slide out of the water drainage hole, and the connecting plate also bends accordingly. When the cleaning hammer encounters the next water drainage hole, the cleaning hammer is quickly pressed into the water drainage hole under the support of the connecting plate, realizing the impact on the residual raw materials in the water drainage hole and flushing the raw materials in the water drainage hole out of the water drainage hole. After that, under the rotation support of the grid frame, the cleaning hammer slides out of the water drainage hole again and moves towards the next water drainage hole. During the rotation of the grid frame, the cleaning hammer is pressed into the water drainage hole again and again and slides out of the water drainage hole again and again, thereby realizing the cleaning of the water drainage holes of the grid frame and improving the cleaning effect of the grid frame.

[0021] 2. While the drying drum rotates around the main shaft, it also meshes with the external gear ring to achieve self-rotation. The drying drum continuously makes a revolution around the main shaft and also rotates around its own central axis. Through the revolution and self-rotation of the drying drum, the raw materials in the drying drum are continuously flipped, enabling the raw materials to be evenly heated.

[0022] The raw materials enter the interior of the drying drum through the gaps between the stirring vanes. Moreover, because the drying drum rotates self, the raw materials will only move from one stirring vane to the next stirring vane and will not directly flow out of the drying drum. After the raw materials are loaded, the rotating disk rotates the driven plate on the driving plate again, making the gap between the two stirring vanes smaller. During the rotation of the drying drum, the stirring vanes press the hot air in the main body into the interior of the drying drum, causing the hot air to flow inside the drying drum, thereby accelerating the drying efficiency of the raw materials.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figures 1-11The present invention provides a technical solution: a potato dehydration and drying device with a self-cleaning function of a grid, the dehydration and drying device comprising a bracket 1, a drain box 2 and a drying box 3, the drain box 2 and the drying box 3 are both mounted on the bracket 1, and the drying box 3 is located below the drain box 2;

[0041] Drain box 2 is equipped with a grid 202 and a gallows 203. Grid 202 is cylindrical and has several drain holes. Gallows 203 is mounted within grid 202. A drive motor 206 is mounted below drain box 2, meshing with grid 202. A lower ratchet is mounted on the outside of the lower end of gallows 203, the outer ring of which meshes with grid 202. An upper ratchet is mounted in the middle of the upper end of gallows 203, connected to drain box 2.

[0042] A discharge belt 205 is mounted at the lower end of the drain box 2. One end of the belt is positioned below the grid 202, while the other end is positioned above the drying box 3. Sliced / stripped material enters the grid 202 through a hopper above the drain box 2 and lands above the gallows 203. Drive motor 206, controlled by a control system, drives the grid 202 forward via gears. This drives the gallows 203 along with the lower ratchet, while the upper ratchet idles. Drive motor 206 drives the grid 202 in reverse, rotating it independently within the drain box 2. The lower ratchet idles, while the upper ratchet drives the gallows 203 normally and prevents it from rotating with it. A scraper is mounted on the upper end of the drain box 2 via a bracket. The scraper's lower end slides in contact with the upper end of the gallows 203. As the grid 202 and gallows 203 rotate together, the raw materials above gallows 203 adhere to the inner wall of the grid 202 due to the centrifugal force. As the grid 202 and gallows 203 rotate, the scraper pushes the raw materials into the spiral portion of gallows 203. Gallows 203 uses the spiral portion to convey the raw materials to the bottom of the drain tank 2. As the raw materials fall to the bottom of the grid 202, they are centrifugally dehydrated. The dehydrated raw materials are pushed by gallows 203 onto the discharge belt 205, which is a conveyor belt. The discharge belt 205 delivers the dehydrated raw materials to the drying box 3, where they are dried.

[0043] A pad and a pad block 208 are installed inside the box body 201 of the drain box 2, a support cylinder is installed on the outside of the pad, the pad block 208 is located at the center of the pad, a bearing plate 209 is installed on the pad block 208, and a fan-shaped notch is opened on the pad block 208 and the bearing plate 209. The drive motor 206 is located on one side of the pad block 208, and one end of the discharge belt 205 is located in the fan-shaped notch. The discharge belt 205 passes through the support cylinder and the box body 201, and the gallows 203 is rotatably mounted on the bearing plate 209;

[0044] A diversion ring 204 is installed on the outer side of the lower end of the grid frame 202. The upper end surface of the diversion ring 204 is a slope surface, and a water drainage groove is opened at the lowest point of the upper end surface of the diversion ring 204. A water outlet pipe is installed below the box body 201. A gear ring 207 is installed at the lower end of the grid frame 202. The lower end of the gear ring 207 is rotatably connected to the support cylinder. The output end of the drive motor 206 is installed with a main gear, and the main gear is meshed with the gear ring 207 for transmission. The drained water slides down through the diversion ring 204 between the box body 201 and the support cylinder and flows out of the box body 201 through the water outlet pipe.

[0045] The gallows 203 includes an upper end plate, a spiral plate 2031 and a central shaft 2033. The central shaft 2033 is fixed in the middle of the spiral plate 2031. The central shaft 2033 penetrates through the middle of the upper end plate. A fan-shaped material opening is opened on the upper end plate. The upper end of the spiral plate 2031 is connected to the position of the fan-shaped material opening. The upper ratchet is installed at the upper end of the central shaft 2033, and the outer ring of the upper ratchet is connected to the box body 201;

[0046] Four stirring shafts 2032 are annularly installed on the spiral plate 2031. The cross section of the stirring shaft 2032 is a right triangle. The surface where the hypotenuse of the stirring shaft 2032 is located is attached to the inner wall of the grid frame 202. The surface where the long right-angled side of the stirring shaft 2032 is located is provided with corrugated grooves. The lower ends of the four stirring shafts 2032 are jointly installed with a driven ring 2034. The driven ring 2034 is located outside the bearing plate 209. The lower ratchet is installed outside the driven ring 2034.

[0047] When the driving motor 206 drives the gear ring 207 to rotate, the grid frame 202 rotates together. When dehydrating the raw materials, the driving motor 206 drives the grid frame 202 to rotate forward. The lower ratchet drives the spiral plate 2031 and the upper end plate to rotate together through the driven ring 2034 and the stirring shaft 2032. Under the centrifugal force, the raw materials continuously approach the edge of the upper end plate and the inner wall of the grid frame 202, and the raw materials are dehydrated under the centrifugal force. When the raw materials are at the edge of the upper end plate and the inner wall of the grid frame 202, the scraper intercepts the raw materials on the upper end plate and pushes the raw materials from the fan-shaped material outlet onto the spiral plate 2031. The continuous rotation of the spiral plate 2031 enables the raw materials to move downward while being under the centrifugal force. During the rotation of the spiral plate 2031, the stirring shaft 2032 uses the corrugated grooves to stir the raw materials, causing the raw materials to tumble in the grid frame 202. After the raw materials fall on the bearing plate, during the rotation of the spiral plate 2031, the lower end of the spiral plate 2031 pushes the raw materials to the fan-shaped notch, causing the raw materials to fall from the fan-shaped notch onto the discharge belt 205, thereby realizing the automatic discharge of the raw materials after dehydration. After the dehydration of the raw materials in the grid frame 202 is completed, in order to clean the raw materials adhering to the inner wall of the grid frame 202, it is necessary to clean the grid frame 202; when cleaning the grid frame 202, the driving motor 206 drives the grid frame 202 to rotate in reverse. When the grid frame 202 rotates in reverse, the upper ratchet at the upper end of the central shaft 2033 restricts the position of the entire gallows 203, and the lower ratchet idles with the gear ring 207. The grid frame 202 rotates in reverse and has a relative movement with the gallows 203. At this time, the stirring shaft 2032 cleans the inner wall of the grid frame 202 when the grid frame 202 rotates, scraping off the residual raw materials on the inner wall, realizing the cleaning of the inner wall of the grid frame 202. After that, the driving motor 206 drives the grid frame 202 to rotate forward again, and the residual raw materials on the spiral plate 2031 are sent out of the drainage tank 2 by the spiral plate 2031.

[0048] A number of connecting plates are arranged on each surface where the short right-angled side of the stirring shaft 2032 is located. One end of the connecting plate is equipped with a hemispherical cleaning hammer 2035. The position of the cleaning hammer 2035 corresponds to the position of the drainage holes on the grid frame 202. The hemispherical cleaning hammer 2035 is located in the drainage holes, and the diameter of the cleaning hammer 2035 is smaller than the diameter of the drainage holes. When relative movement occurs between the stirring shaft 2032 and the grid frame 202, the hemispherical cleaning hammer 2035 is forced to slide out of the drainage holes, and the connecting plate also bends accordingly. When the cleaning hammer 2035 encounters the next drainage hole, the cleaning hammer 2035 is quickly pressed into the drainage hole under the support of the connecting plate, realizing the impact on the residual raw materials in the drainage holes, flushing the raw materials in the drainage holes out of the drainage holes. After that, under the rotation support of the grid frame 202, the cleaning hammer 2035 slides out of the drainage holes again and moves in the direction of the next drainage hole. During the rotation of the grid frame 202, the cleaning hammer 2035 is pressed into the drainage holes again and again and slides out of the drainage holes again and again, thereby realizing the cleaning of the grid frame 202.

[0049] The drying oven 3 includes a main body 301. In the middle position of the main body 301, two main shafts 302 are fixedly installed. At one end of the two main shafts 302 facing each other, a support plate is installed. Between the two support plates, two drying shafts 309 are installed. The drying shaft 309 is connected to the control system;

[0050] A sleeve plate 303 is sleeved on the main shaft 302. Four drying mesh cylinders are rotatably installed between the two sleeve plates 303. A feed inlet is provided on the drying mesh cylinder. Above the main body 301, a feed hopper is installed. One end of the discharge belt 205 is located above the feed hopper. On one side of the main body 301, a cylinder cover 311 is rotatably installed. The outside of the cylinder cover 311 is connected to a driving cylinder (not shown in the figure). The other end of the driving cylinder is rotatably installed on the bracket 1;

[0051] On one side of the main body 301, a drying motor is installed. The output shaft of the drying motor penetrates the main body 301 and a driving gear 310 is installed. The driving gear 310 meshes and drives with the driven gear ring on the sleeve plate 303. Inside the main body 301, external gear rings 304 are installed at positions corresponding to both ends of the drying mesh cylinder. Gear grooves are opened at both ends of the drying mesh cylinder. The external gear ring 304 meshes and drives with the drying mesh cylinder through the gear grooves.

[0052] The external gear ring 304 is composed of two sections of gear rings. The radian of one section of the gear ring is 3 / 2π, and the radian of the other section of the gear ring is 1 / 2π. The gear ring with a radian of 3 / 2π is installed on the main body 301, and the gear ring with a radian of 1 / 2π is installed on the cylinder cover 311.

[0053] A coil is wound inside the drying shaft 309. The coil is connected to the control system. The air in the main body 301 is heated by resistance heat to realize the drying of the raw materials in the drying mesh cylinder. The sleeve plate 303 is sleeved on the main shaft 302. A flange is installed on one side of the sleeve plate 303. Gear grooves are opened on the outside of the flange for meshing and driving with the driving gear 310. The drying motor drives the driving gear 310 to rotate. When the driving gear 310 rotates, the sleeve plate 303 rotates on the main shaft 302, and then the sleeve plate 303 drives the four drying mesh cylinders to rotate. The drying mesh cylinder rotates around its own central axis while rotating around the main shaft 302 and also meshes and drives with the external gear ring 304 to realize self-rotation. The drying mesh cylinder continuously makes a revolution around the main shaft 302 and also rotates around its own central axis. Through the revolution and self-rotation of the drying mesh cylinder, the raw materials in the drying mesh cylinder are continuously turned over, so that the raw materials can be evenly heated. When discharging is required, the driving cylinder works under the control of the control system. The piston rod of the driving cylinder contracts, so that the cylinder cover 311 rotates on the main body 301, opening the discharge through groove on the main body 301. The dried raw materials flow out of the drying mesh cylinder and flow into the next process through the discharge through groove.

[0054] The drying net drum includes two driving plates 305 and several stirring blades 307. A gear groove is provided on the annular side of the driving plate 305. A driving disk is installed on the outer end face of the driving plate 305. The output end of the driving disk is fixed to the sleeve plate 303. A rotating disk 308 is installed in the middle of the inner end face of the driving plate 305. A driven plate 306 is installed on the output end of the rotating disk 308. Several arc grooves are opened on the driving plate 305. Two pins are installed at both ends of each stirring blade 307. One pin is rotatably installed on the driven plate 306, and the other pin is slidably installed in the arc groove.

[0055] The driving disc and the rotating disc 308 are both electric rotating discs, both of which are connected to the control system. The driving disc is used to drive the drying net drum to rotate on the sleeve plate 303. When the raw materials are not dried and do not need to be discharged, the driving disc is not powered and will not self-lock, so that the drying net drum can rotate in the main body 301. When the drying net drum rotates, it is in the forward direction, and the raw materials flow between the several stirring blades 307 and will not flow out of the drying net drum.

[0056] The rotating disk 308 causes the driven plate 306 to rotate on the driving plate 305 , thereby changing the state of the agitating blades 307 , thereby reducing the gap between two adjacent agitating blades 307 or increasing the gap between two adjacent agitating blades 307 .

[0057] After the dehydrated raw materials enter the feed hopper, the rotating disk 308 widens the gap between two adjacent agitating blades 307. As the drying mesh passes through the feed hopper, the raw materials enter the drying mesh through the gaps between the agitating blades 307. Since the drying mesh rotates, the raw materials only move from one agitating blade 307 to the next agitating blade 307 and do not directly flow out of the drying mesh. After the raw materials are loaded, the rotating disk 308 again rotates the driven plate 306 on the driving plate 305, narrowing the gap between the two agitating blades 307. As the drying mesh rotates, the agitating blades 307 press the hot air in the main body 301 into the drying mesh, causing the hot air to flow within the drying mesh, thereby accelerating the drying efficiency of the raw materials.

[0058] When material is to be discharged, the drum cover 311 is opened, and the outer gear ring 304, which has an arc angle of 1 / 2π, rotates along with the drum cover 311, preventing the drying mesh drum from transmitting material to the outer gear ring 304. At this time, the drive disk drives the drying mesh drum to reverse, and the rotating disk 308 increases the gap between two adjacent agitator blades 307, causing the material in the drying mesh drum to flow out from between the agitator blades 307 and out of the main body 301 through the discharge channel. After the material is discharged, the drive disk is powered off, the drum cover 311 is closed again, and the gap between two adjacent agitator blades 307 remains until the next addition of material is completed.

[0059] Working principle of the present invention:

[0060] The sliced / strip raw materials enter the grid 202 through the hopper above the drain box 2 and fall on the top of the gallows 203. The drive motor 206 works under the control of the control system and drives the grid 202 to rotate forward through the gear. The grid 202 drives the gallows 203 to rotate together through the lower ratchet. At this time, the upper ratchet is in an idling state.

[0061] When the drive motor 206 drives the gear ring 207 to rotate, the grid 202 rotates along with it. When dehydrating the raw materials, the drive motor 206 drives the grid 202 to rotate forward. The lower ratchet, through the driven ring 2034 and the stirring shaft 2032, drives the spiral plate 2031 and the upper end plate to rotate together. Under the centrifugal force, the raw materials continue to approach the edge of the upper end plate and the inner wall of the grid 202, and the raw materials are dehydrated under the centrifugal force. When the raw materials are at the edge of the upper end plate and the inner wall of the grid 202, the scraper intercepts the raw materials on the upper end plate and pushes them from the fan-shaped feed opening onto the spiral plate 2031. The continuous rotation of the spiral plate 2031 causes the raw materials to move downward while being centrifuged. During the rotation of the spiral plate 2031, the stirring shaft 2032 uses the corrugated grooves to stir the raw materials, causing them to tumble in the grid 202. After the raw materials fall on the carrying plate, the spiral plate 2031 rotates, and the lower end of the spiral plate 2031 pushes the raw materials to the fan-shaped gap, so that the raw materials fall from the fan-shaped gap to the discharge belt 205, thereby realizing automatic discharge of the raw materials after dehydration.

[0062] When the dehydrated raw materials are fed into the feed hopper by the discharge belt 205, the rotating disk 308 widens the gap between two adjacent agitating blades 307. As the drying mesh passes through the feed hopper, the raw materials enter the drying mesh through the gaps between the agitating blades 307. Since the drying mesh rotates, the raw materials only move from one agitating blade 307 to the next agitating blade 307 and do not flow directly out of the drying mesh. After the raw materials are loaded, the rotating disk 308 again rotates the driven plate 306 on the driving plate 305, narrowing the gap between the two agitating blades 307. As the drying mesh rotates, the agitating blades 307 press the hot air in the main body 301 into the interior of the drying mesh, causing the hot air to flow within the drying mesh, thereby accelerating the drying efficiency of the raw materials.

[0063] When material is to be discharged, the drum cover 311 is opened, and the outer gear ring 304, which has an arc angle of 1 / 2π, rotates along with the drum cover 311, preventing the drying mesh drum from transmitting material to the outer gear ring 304. At this time, the drive disk drives the drying mesh drum to reverse, and the rotating disk 308 increases the gap between two adjacent agitator blades 307, causing the material in the drying mesh drum to flow out from between the agitator blades 307 and out of the main body 301 through the discharge channel. After the material is discharged, the drive disk is powered off, the drum cover 311 is closed again, and the gap between two adjacent agitator blades 307 remains until the next addition of material is completed.

[0064] After the raw materials are dehydrated in the wire mesh rack 202, in order to clean the raw materials adhering to the inner wall of the wire mesh rack 202, the wire mesh rack 202 needs to be cleaned; when cleaning the wire mesh rack 202, the drive motor 206 drives the wire mesh rack 202 to rotate in reverse. When the wire mesh rack 202 rotates in reverse, the upper ratchet wheel at the upper end of the central shaft 2033 restricts the position of the entire winch 203, and the lower ratchet wheel idles with the gear ring 207. The wire mesh rack 202 rotates in reverse and has a relative movement with the winch 203. At this time, when the wire mesh rack 202 rotates, the stirring shaft 2032 cleans the inner wall of the wire mesh rack 202, scraping off the residual raw materials on the inner wall, so as to clean the inner wall of the wire mesh rack 202. After that, the drive motor 206 drives the wire mesh rack 202 to rotate forward again, and the residual raw materials falling on the spiral plate 2031 are sent out of the drainage tank 2 by the spiral plate 2031.

[0065] When a relative movement occurs between the stirring shaft 2032 and the wire mesh rack 202, the hemispherical cleaning hammer 2035 is forced to slide out of the drainage hole, and the connecting plate also bends accordingly. When the cleaning hammer 2035 encounters the next drainage hole, the cleaning hammer 2035 is quickly pressed into the drainage hole under the support of the connecting plate, so as to impact the residual raw materials in the drainage hole and flush the raw materials in the drainage hole out of the drainage hole. After that, under the rotation support of the wire mesh rack 202, the cleaning hammer 2035 slides out of the drainage hole again and moves towards the next drainage hole. During the rotation of the wire mesh rack 202, the cleaning hammer 2035 is pressed into the drainage hole again and again and slides out of the drainage hole again and again, thereby realizing the cleaning of the wire mesh rack 202.
