[0002] Fresh blueberries have a relatively short shelf life and are prone to rot and deterioration, which is not conducive to long-distance transportation and long-term storage. Through drying, the moisture in blueberries can be removed, extending their shelf life and facilitating storage and transportation. Dried blueberries can be sold as dried fruit foods with higher added value. Dried blueberries not only have a unique taste, but also retain the original nutritional value of blueberries, such as vitamins, minerals and antioxidants, and are deeply loved by consumers.

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0044] See also Figures 1 to 10 A blueberry dried fruit drying device and drying method, comprising a first shell 1, a second shell 11 is integrally formed on the upper surface of the first shell 1, a storage component 6 is fixedly installed at one end of the first shell 1, a placement component 2 is fixedly installed at one end of the upper surface of the second shell 11, a drying component 3 is fixedly installed in the middle of the upper surface of the second shell 11, a working component 4 is rotatably installed between the placement component 2 and the drying component 3, the working component 4 is rotatably installed on the second shell 11, a discharging component 5 is fixedly installed on the side of the drying component 3 away from the placement component 2, a plurality of drying trays 9 are arranged inside the drying component 3 and the placement component 2, a fan 8 is fixedly installed on the top of the drying component 3, an input end of the fan 8 is connected to the inside of the heat preservation shell 31 through a third pipe 39, and an output end of the fan 8 is connected to the inside of the placement shell 21 through a first pipe 25.

[0045] When actually used, the blueberries that have been dipped in sugar and cleaned are first neatly spread on the drying tray 9, and then the drying tray 9 is placed in the drying component 3 and the placement component 2 to fill the interior of the drying component 3 and the placement component 2, and then the fan 8 is started. The fan 8 draws air from the interior of the drying component 3, and then the gas is transported to the interior of the placement component 2 through the first pipe 25. The gas that can enter the drying component 3 is heated to achieve a drying effect. Because a large amount of water droplets remain on the surface of the blueberries after being dipped in sugar and cleaned, if they remain on the surface of the blueberries for a long time, it is easy to cause the blueberries to rot. Therefore, the air inside the drying component 3 is introduced into the interior of the placement component 2, which can quickly dry the water droplets on the surface of the first pipe 25. Because the gas is transported to the interior of the placement component 2 after passing through the interior of the drying component 3, the transported gas has absorbed water vapor in the interior of the drying component 3, so when flowing through the placement component 2, only the surface of the blueberries can be dried, and the blueberries will not be over-dried. The blueberries inside the placement component 2 can also be preheated to facilitate subsequent drying work.

[0046] When the blueberries in the drying component 3 are dried, the working component 4 is driven to work. At this time, the working component 4 can push the drying tray 9 that has completed the drying work from the inside of the drying component 3 into the inside of the unloading component 5. At the same time, the undried drying tray 9 in the placement component 2 can be transported into the inside of the drying component 3 for drying. At the same time, the unloading component 5 will be driven to send the dried drying tray 9 into the inside of the second shell 11. The drying tray 9 can be further unloaded in the second shell 11, and the blueberries adhering to the surface can be automatically unloaded and stored in the inside of the second shell 11.

[0047] The working component 4 includes a central shaft 41, a first rotating plate 42 is fixedly installed on the upper end of the central shaft 41, a plurality of evenly distributed spherical protrusions 421 are fixedly installed on the upper surface of the first rotating plate 42, a plurality of spherical grooves matching the spherical protrusions 421 are opened on the lower surface of the drying plate 9, a second rotating plate 43 and a third rotating plate 44 are fixedly installed on the lower end of the central shaft 41, the third rotating plate 44 is located below the second rotating plate 43, a spiral plate 45 is fixedly installed on the upper end of the central shaft 41, and a third motor 17 for driving the central shaft 41 to rotate is fixedly installed on one side of the outer side of the first shell 1.

[0048] A gear is fixedly installed at the bottom end of the central axis 41, and then a chain is used to connect the gear to the driving end of the third motor 17. The second rotating plate 43 and the third rotating plate 44 are both arc-shaped in shape, so that they can better achieve the pushing effect when rotating. The spherical protrusion 421 is used to increase the friction between the drying tray 9 and the first rotating plate 42, thereby improving the connection strength of the drying tray 9 placed on the surface of the first rotating plate 42, making it easier for the first rotating plate 42 to drive the drying tray 9 to move, preventing the drying tray 9 from falling during the movement, and improving the stability during movement.

[0049] The drying component 3 includes a heat-insulating shell 31, and a first slot body 311 and a second slot body 312 are respectively provided on both sides of the upper end of the heat-insulating shell 31, and a third slot body 313 and a fourth slot body 314 are respectively provided on both sides of the lower end of the heat-insulating shell 31. The first rotating plate 42, the second slot body 312 and the first slot body 311 are located at the same horizontal plane, and the second rotating plate 43, the third slot body 313 and the fourth slot body 314 are located at the same horizontal plane. A sealing ring 33 for sealing the second slot body 312 is slidingly sleeved on the outer surface of the upper end of the heat-insulating shell 31, and a baffle 331 is integrally formed on the side of the sealing ring 33 close to the first slot body 311, and the baffle 331 is used to seal the first slot body 311. The unloading component 5 is installed on one side of the fourth slot body 314, and a heating wire 37 is fixedly installed on the inner bottom end of the heat-insulating shell 31. A second pipe 38 for entering air is fixedly installed at the bottom end of the outer surface, and the second pipe 38 is connected to the output end of the external dehumidifier. A plurality of evenly distributed first spring telescopic rods 32 are fixedly installed on the upper surface of the sealing ring 33, and the first spring telescopic rods 32 are fixedly installed on the outer surface of the heat-insulating shell 31. A support plate 34 is fixedly installed on the side of the heat-insulating shell 31 close to the unloading component 5, and a plurality of second spring telescopic rods 35 are fixedly installed on the lower surface of the support plate 34. A sealing plate 36 is fixedly installed on the end of the second spring telescopic rod 35 away from the support plate 34. The inner circle of the sealing ring 33 is designed as an inclined surface, and a sealing shell 30 is fixedly installed on the side of the heat-insulating shell 31 close to the placement component 2. The third groove body 313 is located inside the sealing shell 30, and the second rotating plate 43 is also located inside the sealing shell 30.

[0050] During drying, the gas enters the interior of the heat preservation shell 31 through the second pipe 38, and then passes through multiple drying plates 9 and enters the input end of the fan 8 through the third pipe 39. The heating wire 37 can heat the gas flowing through, thereby drying the blueberries on the drying plates 9. When all the blueberries in the drying component 3 are dried, the central shaft 41 is controlled to rotate, and the first rotating plate 42 is driven to rotate. Because the inner ring of the sealing ring 33 is inclined, the first rotating plate 42 can push the sealing ring 33 upward and pass through the second groove. The first rotating plate 42 is moved out of the heat-insulating shell 31, so that the first rotating plate 42 can be driven to move out of the heat-insulating shell 31 with the rotation of the central shaft 41, and the sealing ring 33 automatically blocks the opening when the first rotating plate 42 enters the heat-insulating shell 31 to prevent the loss of heat, and when the first rotating plate 42 is moved out of the heat-insulating shell 31, the sealing ring 33 can automatically open to facilitate the removal of the first rotating plate 42, and after the first rotating plate 42 is moved out, the sealing ring 33 automatically closes to maintain the sealing of the heat-insulating shell 31, further preventing the loss of heat;

[0051] As the central shaft 41 rotates, the second rotating plate 43 enters the interior of the heat-insulating shell 31 through the third slot 313, and can produce a pushing effect on the lowest drying tray 9. At this time, the lowest drying tray 9 is pushed to slide a distance from the position of the fourth slot 314. At this time, the unloading component 5 clamps the sliding drying tray 9. As the working component 4 continues to rotate, the third rotating plate 44 can drive the unloading component 5 to work and completely move the lowest drying tray 9 out of the interior of the heat-insulating shell 31 and transport it to the interior of the second shell 11. As the central shaft 41 continues to rotate, the first rotating plate 42 enters the interior of the placement component 2 and moves from the placement component 2, the undried drying tray 9 is taken out of the heat preservation shell 31. As the central shaft 41 rotates, the spiral plate 45 first contacts the sealing ring 33, and then pushes the sealing ring 33 upward. At this time, as the central shaft 41 rotates, the first rotating plate 42 can send the undried drying tray 9 into the inner top of the heat preservation shell 31 through the baffle 331. As the working part 4 continues to rotate, when the first rotating plate 42 moves out of the second groove body 312, the drying tray 9 carried thereon will be blocked by the second groove body 312 in the heat preservation shell 31. Under the action of gravity, the drying tray 9 will fall and be stacked on the other drying trays 9. Multiple drying trays 9 stacked together can increase the drying amount that can be dried at the same time.

[0052] When the first rotating plate 42 enters the interior of the heat-insulating shell 31, the first spring telescopic rod 32 can push the sealing ring 33 down. The sealing ring 33 and the baffle 331 can descend to block the second slot body 312 and the first slot body 311 to prevent heat loss. When the first rotating plate 42 moves out of the heat-insulating shell 31, the sealing ring 33 and the baffle 331 can also block the first slot body 311 and the second slot body 312 under the action of the first spring telescopic rod 32, further increasing the sealing performance to prevent heat loss.

[0053] The unloading component 5 includes a support block 51, which is fixedly mounted on the bottom end of the heat-insulating shell 31. A center plate 53 is provided on the side of the support block 51 away from the heat-insulating shell 31. The upper and lower ends of the center plate 53 are fixedly mounted with unloading shells 54. The ends of the two unloading shells 54 close to each other have a lower support plate 541. A support frame 542 is fixedly mounted on the end of the unloading shell 54 away from the lower support plate 541. A conical block 543 is slidingly mounted inside the support frame 542. A rotating shaft 52 is fixedly mounted in the middle of the side of the support block 51 away from the heat-insulating shell 31. The center plate 53 is slidably sleeved on the outside of the rotating shaft 52. A rotating member 5 is rotatably mounted on the end of the rotating shaft 52 away from the support block 51. 5. A return spring 57 is rotatably connected between the rotating member 55 and the center plate 53. A push rod 56 is slidably clamped at the lower end of the support block 51. The push rod 56 and the third rotating plate 44 are located in the same horizontal plane. A connecting rod 551 is fixedly installed on the side of the rotating member 55 close to the center plate 53. A plurality of evenly distributed second ratchet teeth 552 are integrally formed on the side of the connecting rod 551 close to the center plate 53. A first ratchet tooth 531 cooperating with the second ratchet tooth 552 is fixedly installed on the side of the center plate 53 close to the connecting rod 551. The rotating member 55 is rotatably installed on the second housing 11. A first motor 7 is fixedly installed above the material storage component 6. The driving end of the first motor 7 is fixedly installed on the rotating member 55.

[0054] When the second rotating plate 43 pushes the lowermost drying plate 9 inside the heat-insulating shell 31, the drying plate 9 will slide into the upper unloading shell 54 through the fourth slot 314, and in this process the conical block 543 will be pushed up until the drying plate 9 is completely pushed and fits with the unloading shell 54. At this time, the conical block 543 will fall down under the action of gravity, and the lower support plate 541 will cooperate with the conical block 543 and the support frame 542 to firmly clamp the drying plate 9. When the central shaft 41 rotates to drive the third rotating plate 44 to rotate, the third rotating plate 44 will push the pushing rod 56 to slide, and the pushing rod 56 will have a pushing effect on the central plate 53. At this time, the pushing rod 56 will push the central plate 53 and the two unloading shells 54 to move, and the upper unloading shell 54 will drive the drying plate 9 to move and make it completely move out of the interior of the heat-insulating shell 31. At this time, the rotating shaft 52 is compressed until the first The ratchet 531 is in contact with the second ratchet 552. At this time, the first motor 7 can drive the center plate 53 to rotate. The rotation of the center plate 53 can drive the two unloading shells 54 to rotate. The upper unloading shell 54 drives the drying plate 9 to rotate downward, and the lower empty unloading shell 54 is rotated upward. At this time, the third rotating plate 44 loses its effect on the center plate 53, and the center plate 53 is pushed back to its original position under the action of the reset spring 57. At the same time, a conical block 543 at the bottom will slide out of the interior of the support frame 542 under the action of gravity, and lose its clamping effect on the drying plate 9. The drying plate 9 will fall into the interior of the second shell 11 under the action of gravity, realizing the circulation of the unloading component 5, not only can the dried drying plate 9 be removed from the interior of the heat preservation shell 31, but the drying plate 9 can also be turned upside down and sent into the interior of the second shell 11, so as to facilitate the subsequent removal of the dried blueberries from the drying plate 9.

[0055] The placement component 2 includes a placement shell 21, a placement groove 22 is provided at the upper end of the placement shell 21, a loading groove 23 is provided at the lower end of the placement shell 21, the loading groove 23 separates the placement shell 21 into a bottom plate 24, a plurality of evenly distributed T-slots 241 are provided on the upper surface of the bottom plate 24, a T-rod 242 is rotatably installed inside the T-slot 241, a torsion spring is fixedly connected between the T-rod 242 and the T-slot 241, and a sealing door 221 is hinged inside the placement groove 22.

[0056] In the initial state, under the action of the torsion spring, all T-shaped rods 242 are in a vertical state. At this time, the drying tray 9 placed inside the shell 21 is supported by multiple T-shaped rods 242. When the first rotating plate 42 gradually moves into the interior of the loading trough 23, a part of the T-shaped rods 242 are pushed down until the first rotating plate 42 completely enters the interior of the loading trough 23. At this time, all T-shaped rods 242 are pushed down and lose their supporting force on the drying tray 9. The drying tray 9 will fall on the surface of the first rotating plate 42 under the action of gravity. As the first rotating plate 42 rotates, due to the spherical protrusions 421. Therefore, the drying tray 9 at the bottom will be driven for transmission, and when the first rotating plate 42 gradually leaves the loading chute 23, a part of the T-shaped rods 242 will pop up to support the remaining drying trays 9. When the first rotating plate 42 is completely moved out of the loading chute 23, all the T-shaped rods 242 will pop up under the action of the torsion springs to support the remaining drying trays 9, thereby achieving that as the first rotating plate 42 continues to rotate, the undried drying tray 9 can be automatically taken out from the inside of the placement shell 21 and transported to the inside of the heat preservation shell 31 for drying, thereby achieving continuous processing and automatic loading without stopping.

[0057] An inclined plate 14 is fixedly installed at the inner bottom end of the first shell 1, a third shell 12 is fixedly installed at one end of the first shell 1 away from the material storage part 6, a material taking trough 121 is provided at the bottom end of the third shell 12, two symmetrical support rods 16 are provided above the inclined plate 14, the support rods 16 are fixedly installed inside the first shell 1, a plurality of evenly distributed cams 15 are rotatably installed on both sides of the first shell 1 corresponding to the two support rods 16, the cams 15 on the same side are driven by a conveyor belt, and a plurality of second motors 13 for driving the cams 15 to rotate are fixedly installed outside the first shell 1.

[0058] When the drying tray 9 falls into the second shell 11, the drying tray 9 will fall on the two support rods 16. At this time, the second motor 13 can drive all the cams 15 to work. Because of the special shape of the cam 15, the drying tray 9 will continue to vibrate and be continuously transported toward the third shell 12. Because the sugar on the surface of the blueberries after being soaked in sugar will cause them to adhere to the surface of the drying tray 9 after drying, the vibration generated by the cam 15 can shake the dried blueberries off the drying tray 9, thereby automatically separating the drying tray 9 from the dried blueberries. As the cam 15 is continuously driven, the empty drying tray 9 will be transported to the inside of the third shell 12 for stacking, which is convenient for workers to take.

[0059] The shaken blueberry dried fruits will fall onto the inclined plate 14. When the cam 15 vibrates, the inclined plate 14 will also vibrate. Because the inclined plate 14 is inclined, the vibration generated by the cam 15 will cause the blueberry dried fruits to slide into the interior of the storage part 6 and be stored.

[0060] The material storage component 6 includes a material storage shell 61, which is connected to the interior of the first shell 1. A discharge trough 62 is provided at the inner bottom of the material storage shell 61. A sliding plate 63 is provided on the side of the material storage shell 61 away from the first shell 1 for sliding. The sliding plate 63 is used to close and open the discharge trough 62.

[0061] When it is necessary to take out the dried blueberries, one only needs to pull out the sliding plate 63, and the dried blueberries will fall out from the discharge chute 62, making it convenient for workers to take them out at one time.

[0062] A method for drying dried blueberries comprises the following steps:

[0063] S1: When in use, first fill the interior of the placement component 2 and the drying component 3 with the drying tray 9, the interior of the drying tray 9 is filled with blueberries, and the heating wire 37 is controlled to work to preheat the interior of the heat preservation shell 31;

[0064] S2: After the preheating is completed, the fan 8 is driven to work, and the fan 8 drives the gas from the outside of the device into the inside of the heat preservation shell 31, and finally transports it to the inside of the placement shell 21;

[0065] S3: When unloading is required, the working component 4 is driven to work, the second rotating plate 43 can deliver the drying plate 9 inside the heat-insulating shell 31 to the unloading component 5, and the third rotating plate 44 can drive the unloading component 5 to unload the output drying plate 9, and the device remains sealed during this process;

[0066] S4: During the unloading process, the first rotating plate 42 can load the unprocessed drying tray 9 from the inside of the placement component 2 and transport it to the inside of the drying component 3 for drying;

[0067] S5: When in use, the unloading component 5 can turn the dried drying tray 9 upside down, so that the dried blueberries are separated from the drying tray 9.

[0068] Working principle: During actual use, first turn on the fan 8 to dry the blueberries inside the drying component 3. Then, when it is necessary to unload the drying tray 9 inside the drying component 3, you only need to control the third motor 17 to drive the working component 4 to rotate. The rotation of the working component 4 can automatically unload the drying tray 9 inside the drying component 3 through the second rotating plate 43. As the working component 4 continues to rotate, the third rotating plate 44 can drive the unloading component 5 to turn the drying tray 9 after drying upside down into the interior of the second shell 11. As the working component 4 continues to rotate, the first rotating plate 42 can automatically take out the unprocessed drying tray 9 from the interior of the placement component 2, and transport it into the interior of the heat preservation shell 31 through the first trough body 311. Automatic loading and unloading can be achieved without stopping the machine, thereby achieving continuous drying and increasing the drying effect and drying rate.

[0069] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
