DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-3 A dryer for freeze-dried fruit production includes a drying box 1, a lifting device is fixedly connected to the bottom wall of the drying box 1, and a storage bucket 13 is connected to the output end of the lifting device. A cover plate 2 is fixedly installed on the upper end surface of the drying box 1, and a motor 4 is fixedly connected to the upper end surface of the cover plate 2 through two fixing rods 3. The output shaft of the motor 4 passes through the upper end surface of the cover plate 2 and extends into the drying box 1 to be installed with a transmission device. Two stirring devices are symmetrically connected to the output end of the transmission device, and the output ends of the two stirring devices are both in contact with the inner wall of the storage bucket 13. Two ventilation devices are symmetrically connected to the lower end surface of the cover plate 2, and the output ends of the two ventilation devices are both connected to the output end of the transmission device.

[0022] The lifting device includes a hydraulic telescopic cylinder 14 , which is fixedly mounted on the inner bottom wall of the drying box 1 . A clamping block 15 is fixedly mounted on the output shaft of the hydraulic telescopic cylinder 14 , and the clamping block 15 is connected to the bottom end of the storage barrel 13 .

[0023] The transmission device includes a connecting shaft 5, and the upper end surface of the connecting shaft 5 is fixedly connected to the output shaft of the motor 4. A mounting sleeve 6 is fixedly provided on the outer wall of the connecting shaft 5, and the output end of the stirring device is fixedly connected to the outer wall of the mounting sleeve 6. A driving gear 8 is fixedly installed at one end of the connecting shaft 5, and the output ends of the two ventilation devices are both connected to the driving gear 8.

[0024] Each stirring device includes a fixed plate 7, and the fixed plate 7 is fixedly mounted on the outer wall of the mounting sleeve 6. A plurality of connecting blocks 11 are equidistantly provided at one end of the fixed plate 7. A scraper 12 is fixedly connected to one end of the plurality of connecting blocks 11 away from the fixed plate 7, and the outer wall of the scraper 12 contacts the inner wall of the storage barrel 13. The freeze-dried food located at the center of the storage barrel 13 can be stirred out of the center point by rotating the fixed plate 7.

[0025] Each ventilation device includes a fixed shaft 9, and the fixed shaft 9 is rotatably connected to the lower end surface of the cover plate 2. A driven gear 17 is fixedly mounted on the outer wall of the fixed shaft 9, and the driven gear 17 is engaged with the driving gear 8. It should be noted that the diameter of the driving gear 8 is larger than the diameter of the driven gear 17, and when the driving gear 8 rotates one circle, the driven gear 17 should rotate more circles. A plurality of fan blades 10 are also provided on the outer wall of the fixed shaft 9. When the plurality of fan blades 10 rotate, the air flow rate in the drying box 1 can be accelerated.

[0026] A slot 16 is formed on the lower end surface of the storage tub 13, and the block 15 is slidably engaged in the slot 16.

[0028] At the same time, the rotation of the mounting sleeve 6 will drive the two fixed plates 7 to rotate synchronously, and the fixed plates 7 will evenly stir the frozen-dried fruits in the storage barrel 13, so that the frozen-dried fruits located in the center of the storage barrel 13 are heated unevenly. At the same time, the fixed plates 7 will drive the multiple connecting blocks 11 and the scraper 12 to rotate. The rotation of the scraper 12 can prevent the frozen-dried fruits from adhering to the inner wall of the storage barrel 13.

[0029] When drying is completed, the storage barrel 13 is lifted into the drying box 1 using the hydraulic telescopic cylinder 14 .

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
