Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving rapid drying of fruits and vegetables, and particularly to a drying device for energy-saving rapid drying of fruits and vegetables. Background Art

[0002] The core purpose of drying existing fruits and vegetables is to extend the shelf life, enhance the product value, and meet the market demand. At the same time, fruit and vegetable drying is a core link in agricultural deep processing. Through physical dehydration, the shelf life can be increased from several days to several years, the transportation cost can be reduced by more than 80%, and the product added value can be increased by 3 - 5 times.

[0003] Currently, during the drying process of fruits and vegetables, the fruits and vegetables are placed on the drying mesh trays on the drying racks, and the fruits and vegetables are prone to stacking with each other, such as blocky carrot dices, potato pieces, etc. And during the drying process, along with the evaporation of water in the fruits and vegetables, the precipitation of sugars or viscous substances will occur, which will lead to the phenomenon of mutual adhesion of fruits and vegetables during drying. The mutual adhesion of fruits and vegetables not only makes it difficult to ensure the appearance shape of the dried fruits and vegetables, resulting in appearance damage and affecting the marketability, but also the moisture distribution in the adhesion part is uneven, resulting in over-drying or over-wetting in some areas, with a hard or sticky taste. Further, when the temperature in the adhesion area is too high, heat-sensitive nutrients such as vitamins may be damaged. For this reason, we propose a drying device for energy-saving rapid drying of fruits and vegetables. Summary of the Invention

[0056] Specific implementation process: In this embodiment, when the drying tray 31 is placed on the two support bottom plates 41 of the drying rack body 3, or when the drying tray 31 is removed from the drying rack body 3, then manually squeeze the two clamping plates 571, so that the two clamping plates 571 drive the clamping rods 572 thereon to disengage from the clamping holes. Subsequently, hold the two clamping plates 571 by hand and simultaneously push the connecting shell 56 upward along the clamping groove 531 until the two clamping rods 572 are respectively clamped in the two clamping holes at the top of the clamping groove 531. That is, at this time, when the connecting shell 56 moves upward, the contact turning member 58 is further moved upward, and the contact turning member 58 is located above the drying tray 31. At this time, it does not affect the placement or removal of the drying tray 31. And when the drying tray 31 is placed, squeeze the two clamping plates 571 again, so that the clamping rods 572 are clamped in the two clamping holes at the bottom of the clamping groove 531, so that the bottom of the contact turning member 58 contacts the bottom end inside the drying tray 31.

[0057] The contact turning member 58 is installed at the bottom of the connection shell 56, and the contact turning member 58 is used to turn the fruits and vegetables in the drying tray 31.

[0059] The protective shell 543 is fixedly installed on one side of the drying rack body 3, and the protective shell 543 is sleeved on the outer side of the moving block 541. One end of the reciprocating lead screw 542 is rotatably connected to the protective shell 543, and the other end of the reciprocating lead screw 542 passes through the protective shell 543 and is connected to the synchronous drive mechanism 6.

[0060] The adjusting member 55 includes an adjusting plate 551 and a guide rod 552. Adjusting grooves 511 are provided on both of the two moving plates 51, and both ends of the adjusting plate 551 are slidably connected to the two adjusting grooves 511 respectively.

[0061] The contact turning member 58 includes an air inlet shell 581, an air inlet sleeve 582, a turning pipe 583, a connecting hose 584 and a connecting frame 585. The air inlet shell 581 is connected to the bottom of the connection shell 56. There are multiple air inlet sleeves 582, and one end of each of the multiple air inlet sleeves 582 is communicated with the air inlet shell 581. The other end of the air inlet sleeve 582 is communicated with the turning pipe 583. Multiple turning pipes 583 are all made of rubber material, and the turning pipe 583 is used to move and turn the fruits and vegetables during the drying process;

[0062] Specific implementation process: During the process of drying fruits and vegetables on the multiple drying trays 31 of the drying rack body 3, the multiple reciprocating lead screws 542 on the drying rack body 3 rotate synchronously under the drive of the synchronous drive mechanism 6. As the reciprocating lead screw 542 rotates, further driving force is provided to the moving block 541. Further, the moving block 541 drives the guide plate 53 to move along the drying tray 31 through the two moving plates 51 and the two connecting rods 52. When the guide plate 53 moves, it drives the multiple turning tubes 583 to move along the inside of the drying tray 31, realizing slow turning of the fruits and vegetables inside the drying tray 31. In this embodiment, the turning tube 583 is made of rubber material, preferably silicone rubber, which meets the safety standards, so as not to damage the fruits and vegetables. As the drying progresses, the material of the turning tube 583 becomes softer, playing a role in further protecting the dried fruits and vegetables during turning;

[0063] And during the movement of the moving plate 51, due to the limiting effect of the limiting rod 553 at one end of the guide rod 552, when the limiting rod 553 moves to the bottom of the limiting groove 32, the limiting rod 553 causes the adjusting plate 551 to move downward relative to the adjusting grooves 511 of the two moving blocks 541. When the adjusting plate 551 moves downward, through the inclined groove 5511, the guide plate 53 moves horizontally relative to the drying tray 31. At this time, the multiple turning tubes 583 move to the position of alternating turning. As the reciprocating lead screw 542 continues to rotate, the moving block 541 drives the moving plate 51 and the guide plate 53 to move back along the drying tray 31, further realizing turning and drying of the fruits and vegetables to prevent the fruits and vegetables from sticking to each other;

[0064] One end of the connecting hose 584 is connected to the air inlet housing 581, and the other end of the connecting hose 584 is connected to the synchronous drive mechanism 6. One end of the connecting frame 585 is fixedly connected to the moving block 541, and the connecting frame 585 is fixedly sleeved outside the connecting hose 584. An opening is provided on the protective housing 543 corresponding to the position of the connecting frame 585;

[0065] Specific implementation process: As the moving block 541 moves, it drives the connecting hose 584 to move synchronously through the connecting block. Due to the setting of the connecting hose 584, when the air inlet housing 581 moves upward or downward relative to the guide plate 53, or the air inlet housing 581 moves up and down with the guide plate 53, the connecting hose 584 can still be stably connected to the air inlet housing 581;

[0066] At this time, a small amount of hot air is introduced through the hot air branch pipe 7. Meanwhile, under the connection action of the synchronous driving mechanism 6, the hot air enters the connecting hose 584, and finally discharges from the bottom of the turning pipe 583 through the air inlet housing 581 and the air inlet sleeve 582. While the turning pipe 583 is turned, the hot air is used to quickly dry the turned fruits and vegetables.

[0067] At the top inside the drying chamber 1, there is a hot air branch pipe 7, and a connecting transmission mechanism 8 is provided at the hot air branch pipe 7. The connecting transmission mechanism 8 is used to drive a plurality of synchronous driving mechanisms 6.

[0072] Specific implementation process: Push the drying rack body 3 into the drying chamber 1. At the same time, move the locking plate 672 on one side of the drying rack body 3 to the positioning opening 911. Subsequently, lift the locking plate 672 upward so that the bottoms of the two locking plates 672 are inserted into the positioning opening 911. At this time, the locking rods 673 of the two locking plates 672 are connected by the locking springs 674, and the locking rods 673 are clamped in the positioning holes 912. At this time, the relative fixation between the drying rack body 3 and the drying chamber 1 is realized, and at the same time, the self-braking universal wheels of the drying rack body 3 are locked;

[0073] At the same time, in this embodiment, while aligning the locking plate 672 with the positioning opening 911 and placing it, insert the synchronizing block 66 into the square groove, and the connection between the synchronizing block 66 and the connecting transmission mechanism 8 can be realized.

[0076] Specific implementation process: During the process of drying the fruits and vegetables on the drying rack body 3 inside the drying chamber 1, the heating and air supply mechanism 2 operates to form a circulating hot air inside the drying chamber 1. At the same time, a small part of the air flow enters the hot air branch pipe 7. Then, through the operation of the servo motor 86, the synchronizing rod 85 drives multiple fourth bevel gears 84 to rotate. When the fourth bevel gear 84 rotates, the third bevel gear 83 drives the rotating block 81 and the rotating block 81 to rotate. When the rotating block 81 rotates, it drives the synchronizing rod 85 to rotate through the square groove. At this time, the synchronizing rods 85 on multiple drying rack bodies 3 rotate synchronously. And as the synchronizing rod 85 rotates, it drives the air inlet pipe 65 at its bottom to rotate. The air inlet pipe 65 drives the second bevel gear 63 to rotate through the rotating sleeve 64. When the second bevel gear 63 rotates, the first bevel gear 62 drives the reciprocating lead screw 542 to rotate;

[0077] And since the rotary tube 82 is connected to the hot air branch pipe 7, hot air flow is introduced into the rotary tube 82, enters the intake pipe 65 through the square groove, then enters the connecting hose 584 through the transfer housing 61. Subsequently, the hot air flow guides the air flow to the tumbling fruits and vegetables through the tumbling tube 583, realizing rapid drying of the fruits and vegetables and preventing the fruits and vegetables from sticking.
