A cutting groove 725 is formed on the upper side of the receiving frame 704; a connecting plate 726 is slidably connected within the cutting groove 725. The bottom of the connecting plate 726 is connected to the upper side of the second closing plate 705 by bolts. A linear motor 727 is connected to the side of the box body 1 close to the receiving frame 704 by bolts. The output end of the linear motor 727 is connected to the side of the connecting plate 726 opposite thereto by bolts. Two symmetric convex blocks are connected to the upper side of the heat insulation plate 703 by bolts. Torsion springs 708 are provided on the convex blocks; the ends of the two torsion springs 708 away from the convex blocks are both connected to a limiting member 709 by bolts. The sides of the two limiting members 709 opposite to the first closing plate 706 are both in contact. An exhaust fan 5 is provided on the outer part of the moisture collecting pipe 4. The output end of the exhaust fan 5 is connected to the moisture collecting pipe 4 through an air duct; two symmetric fixing brackets one 710 and fixing brackets three 717 are connected to the bottom of one of the guide rails 702 by bolts. A winding roller one 711 and a winding roller two 718 are respectively rotatably connected to the fixing brackets one 710 and fixing brackets three 717 through bearings. A motor one 712 is connected to the outer part of the fixing bracket one 710 by bolts. The output end of the motor one 712 is connected to the bottom of the winding roller one 711 through a coupling. A gear one 716 and a gear two 719 are respectively connected to the upper sides of the winding roller one 711 and the winding roller two 718 by bolts; fixing brackets two 713 and fixing brackets four 720 are connected to the bottom of the guide rail 702 on the same side as the motor one 712 by bolts. The fixing brackets one 710 and fixing brackets three 717 are located between the fixing brackets two 713 and fixing brackets four 720. A guiding roller one 714 and a guiding roller two 721 are respectively rotatably connected to the fixing brackets two 713 and fixing brackets four 720 through bearings; the same wire rope two 722 is wound around the winding roller two 718 and the guiding roller two 721. The end of the wire rope two 722 away from the winding roller two 718 is connected to a second convex block 723 by bolts. The upper side of the second convex block 723 is connected to the bottom of the heat insulation plate 703 by bolts. The same wire rope one 715 is wound around the outer parts of the winding roller one 711 and the guiding roller one 714. The end of the wire rope one 715 away from the winding roller one 711 is connected to a first convex block 724 by bolts. The upper side of the first convex block 724 is connected to the bottom of the heat insulation plate 703 by bolts.

[0030] Specifically, after the undried fruits and vegetables fall onto the second conveyor belt 10, start the first motor 712. The first motor 712 drives the first wire winding roller 711 to rotate, so that the first wire winding roller 711 winds up the first steel wire rope 715, and the first bump 724 connected to the heat insulation plate 703 drives the heat insulation plate 703 to move along the guide rail 702 towards the discharge port 3. After the heat insulation plate 703 fits against the inner wall of the box body 1, the air holes 707 on the heat insulation plate 703 and the first closing plate 706 will reduce the passing rate of the hot air inside the whole box body 1. When there are high water content requirements for the fruits and vegetables, start the first motor 712 to reverse it, so that the second wire winding roller 718 winds up the second steel wire rope 722, and the second bump 723 connected to the second steel wire rope 722 pulls the heat insulation plate 703 back to its original position. Start the linear motor 727, and the linear motor 727 makes the connecting plate 726 push the second closing plate 705 to drive the first closing plate 706 to move towards the inner wall of the box body 1 on the side away from the discharge port 3. After the first closing plate 706 completely fits against the inner wall of the box body 1, the second closing plate 705 will coincide with the heat insulation plate 703 and cover the air holes 707 on the heat insulation plate 703 to prevent the hot air from flowing through. The hot air can only flow out through the heat insulation plate 703 on the forward-moving first closing plate 706, so as to conduct regional control over the drying temperature inside the box body 1.

[0031] In a specific application scenario, the zone temperature control module 7 is mainly applicable to the zone temperature control link in the zone temperature control process, that is, the zone temperature control module 7 can enable the device to quickly adjust the temperature according to the types and thicknesses of the dried fruits and vegetables during the drying process of the fruits and vegetables, so as to control the drying degree of the fruits and vegetables, effectively control the water content of the fruits and vegetables, improve the precise control of the drying degree of the fruits and vegetables by the device, and improve the taste of the dried fruits and vegetables while ensuring the drying effect of the fruits and vegetables.

[0032] Refer to Figure 7 and Figure 8, in a preferred embodiment, the bottom of the discharge port 3 is bolted to the upper side of the drainage frame 801. A sloping panel 804 is provided below the drainage frame 801, and a roller conveyor belt 802 is provided below the sloping panel 804. A packing box 803 is placed on the roller conveyor belt 802. Two symmetrical slotted plates 805 are slidably connected to the outside of the sloping panel 804. One side of each of the two slotted plates 805 facing the box body 1 is bolted. Two symmetrical moving pieces 809 are provided outside one of the slotted plates 805. One of the moving pieces 809 is bolted to the side of the slotted plate 805 on the same side facing it, and the other moving piece 809 is bolted to the outside of the sloping panel 804. A same spring 810 is bolted to the opposite sides of the two moving pieces 809. Two symmetrical bases are bolted to the outside of the slotted plate 805 away from the moving piece 809 among the two slotted plates 805. A same threaded rod 807 is rotatably connected to the two bases through bearings. A driving motor 806 is bolted to the outside of one of the bases. The output end of the driving motor 806 is connected to one side of the threaded rod 807 through a coupling. An active part 808 is provided on the outside of the threaded rod 807. The side of the active part 808 facing the sloping panel 804 is bolted.

[0033] Specifically, the dried fruits and vegetables fall from the discharge port 3 onto the drainage frame 801 through the conveyance of the conveyor belt three 9, gather in the drainage frame 801 and then fall onto the sloping panel 804, and finally enter the packing box 803. Start the driving motor 806. The driving motor 806 drives the threaded rod 807 to rotate, so that the active part 808 drives the sloping panel 804 to reciprocate on the slotted plate 805, so that the dried fruits and vegetables falling on the sloping panel 804 can move with the movement of the sloping panel 804 and be laid flat layer by layer in the packing box 803.

[0034] In a specific application scenario, the uniform packing module 8 is mainly applicable to the uniform packing link in the uniform packing process. That is, the uniform packing module 8 uses the slotted plate 805 and the sloping panel 804 to enable the device to make the dried fruits and vegetables falling from the drainage frame 801 be evenly and layer-by-layer spread on the packing box 803 through reciprocating motion, so that the dried fruits and vegetables in the packing box 803 can be evenly distributed, avoiding excessive accumulation of the dried fruits and vegetables in a single part, so that the packing box 803 will not have the situation of fruit and vegetable extrusion and breakage after packing, improving the product quality and ensuring the product competitiveness.

[0035] Working principle: After the undried fruits and vegetables fall onto conveyor belt two 10, start motor one 712. Motor one 712 drives winding roller one 711 to rotate, so that winding roller one 711 winds up steel wire rope one 715, causing bump one 724 connected to heat insulation plate 703 to drive heat insulation plate 703 to move along guide rail 702 in the direction of discharge port 3. After heat insulation plate 703 fits against the inner wall of box body 1, the air holes 707 on heat insulation plate 703 and closing plate one 706 will reduce the passing rate of hot air inside the whole box body 1. When there are relatively high water content requirements for the fruits and vegetables, start motor one 712 to reverse it, so that winding roller two 718 winds up steel wire rope two 722, and then pulls heat insulation plate 703 back to its original position through bump two 723 connected to steel wire rope two 722. Start linear motor 727. Linear motor 727 makes connecting plate 726 push closing plate two 705 to drive closing plate one 706 to move towards the inner wall of box body 1 on the side away from discharge port 3. After closing plate one 706 completely fits against the inner wall of box body 1, closing plate two 705 will coincide with heat insulation plate 703 and cover the air holes 707 on heat insulation plate 703 to prevent hot air from flowing through. The hot air can only flow out through heat insulation plate 703 on the forward moving closing plate one 706, so as to conduct regional control over the drying temperature inside box body 1. The dried fruits and vegetables fall from discharge port 3 onto diversion frame 801 through the conveyance of conveyor belt three 9, gather in diversion frame 801 and then fall onto inclined panel 804, and finally enter packing box 803. Start drive motor 806. Drive motor 806 drives threaded rod 807 to rotate, so that movable part 808 drives inclined panel 804 to reciprocate on grooved plate 805, so that the dried fruits and vegetables falling on inclined panel 804 can be laid flat layer by layer in packing box 803 as inclined panel 804 moves.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
