[0022] Referring to the attached Figures 1 - 3 , a drying device for processing shiitake mushrooms, including a tray frame 1. The tray frame 1 is generally rectangular. Ten mutually parallel butterfly nets 4 are rotatably installed in the inner frame of the tray frame 1. The ten butterfly nets 4 are arranged in a straight line at equal intervals, and the outer circles between adjacent two butterfly nets 4 always remain tangent to each other.

[0023] In this embodiment, the butterfly net 4 is specifically composed of two rectangular net plates 401, two arc-shaped net plates 403 and two cylinders 402. The width of the rectangular net plate 401 is 2.5 cm or 3 cm or 4 cm or 5 cm. The rectangular net plates 401 with widths of 2.5 cm or 3 cm or 4 cm or 5 cm are respectively used to place small, medium, large, and extra-large shiitake mushrooms. The diameter of small shiitake mushrooms is 2.5 - 3 cm, the diameter of medium shiitake mushrooms is 3 - 4 cm, the diameter of large shiitake mushrooms is 4 - 5 cm, and the diameter of extra-large shiitake mushrooms is 5 - 6.5 cm. The two cylinders 402 are respectively rotatably installed in the inner frames on both sides of the tray frame 1. The two rectangular net plates 401 are fixedly connected in a V shape, and the included angle between the upper surfaces of the two rectangular net plates 401 is less than 180° and greater than 90°. In this embodiment, 135° is specifically adopted, and the preset rotation angle of the butterfly net 4 is 45°;

[0024] The upper edges of the two arc-shaped net plates 403 are respectively fixedly installed below the outer edges of the two rectangular net plates 401. The two cylinders 402 are respectively fixedly installed at both ends of the V-shaped connected rectangular net plates 401. And the central axes of the two arc-shaped net plates 403 in the butterfly net 4 and the central axes of the two cylinders 402 are parallel to each other, and the arc-shaped net plates 403 between adjacent two butterfly nets 4 are always tangent to each other, that is, the distance between adjacent two butterfly nets 4 is the same as the diameter of the arc-shaped net plate 403, and the arc-shaped net plates 403 on the outer sides of the two outermost butterfly nets 4 respectively fit with the inner frame of the tray frame 1.

[0025] In this embodiment, a transmission mechanism is arranged between the ten butterfly nets 4. The transmission mechanism includes ten semi-gears 6 and a segmented rack 7. The ten butterfly nets 4 are driven by a power source and the reciprocating output of the transmission mechanism to synchronously drive the ten butterfly nets 4 to rotate reciprocally around the cylinder 402 by a preset angle. The power source is specifically composed of an electric push cylinder 5. Strip-shaped teeth 9 are fixedly installed at equal intervals on the segmented rack 7. The ten semi-gears 6 are respectively coaxially fixedly installed on the cylinders 402 at one end of the ten butterfly nets 4. The ten strip-shaped teeth 9 on the segmented rack 7 are respectively meshed with the ten semi-gears 6. The end of the push rod of the electric push cylinder 5 is coaxially fixedly connected to one end of the segmented rack 7. The housing of the electric push cylinder 5 is fixedly connected to the tray frame 1. The ten semi-gears 6 and the segmented rack 7 that are meshed with each other are used to synchronously connect the rotations of the ten butterfly nets 4.

[0026] In this embodiment, a gear box 2 is arranged outside the transmission mechanism. The gear box 2 is fixedly connected to the tray frame 1. One side of the gear box 2 is fixedly installed with a box cover 3 by screws. The lower surface and the back surface of the segmented rack 7 are in contact with the inner wall of the gear box 2. The upper end of the segmented rack 7 is meshed and pressed below the semi-gear 6 through the strip-shaped teeth 9. A limiting strip 8 in contact with each other is arranged on the front side of the segmented rack 7. The limiting strip 8 is fixedly connected to the inner wall of the gear box 2. The housing of the electric push cylinder 5 is fixedly installed in the gear box 2.

[0027] In the present utility model, when the dried mushrooms are laid flat by the drying equipment for mushroom processing and placed in a mushroom dryer for drying, after the mushrooms are laid flat on the ten butterfly nets 4 in the tray frame 1, referring to Figure 3 , the mushrooms on the butterfly net 4 will automatically roll from the inclined rectangular net plate 401 on the butterfly net 4 to the horizontal rectangular net plate 401. That is, the mushrooms above the tray frame 1 are arranged and laid flat in ten straight lines. In this application, the rectangular net plates 401 in the ten butterfly nets 4 are used as the supporting surfaces for placing mushrooms on the tray frame 1. Compared with the traditional trays for placing mushrooms, the air permeability is better and the mushrooms are heated more evenly;

[0028] During the drying process of the mushrooms above the tray frame 1 in the dryer, the push rod in the electric push cylinder 5 can be telescoped regularly. When the push rod in the electric push cylinder 5 extends or contracts, the push rod in the electric push cylinder 5 can drive the segmented rack 7 in the transmission mechanism to move along the inner wall of the gear box 2, and the ten semi-gears 6 and the ten strip-shaped teeth 9 in the transmission mechanism can drive the ten butterfly nets 4 to rotate clockwise or counterclockwise by 45° along the tray frame 1 at the same time. The rotating butterfly net 4 can turn over the mushrooms on the butterfly net 4, thus realizing the automatic turning of the mushrooms;

[0029] Turning the shiitake mushrooms over can ensure that all parts of the shiitake mushrooms are evenly heated, avoiding over-drying of some parts while other parts remain moist, thus maintaining the overall quality of the shiitake mushrooms. By turning the shiitake mushrooms, the speed of water evaporation can also be accelerated, because turning over can reduce the uneven drying caused by some parts being in contact with hot air for a long time, thereby improving the drying efficiency. At the same time, appropriate turning helps to prevent the deformation or color change of the shiitake mushrooms caused by long-term drying, and maintain their original flavor and nutrition. Therefore, during the drying process of shiitake mushrooms, it is very necessary to turn them over in a timely manner. It can not only accelerate the drying process, but also ensure the quality and taste of the shiitake mushrooms.

[0030] 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 substitutions or changes, and should be covered by the protection scope of the present invention.
