In addition, the steam pipe assembly 7 and the toggle drying assembly 6 cooperate with each other to steam dry the edible fungi, and the edible fungi can be turned over during drying, thereby ensuring that the device can ensure that the edible fungi are heated evenly during drying even when drying a large number of edible fungi, thereby improving the drying efficiency.

[0055] Furthermore, the switch assembly 4 includes a fixed rod 43, both ends of which are fixedly mounted on the discharge door 3 through a second support seat 42, both ends of the fixed rod 43 are rotatably mounted with a first support seat 41, and the first support seat 41 is fixedly mounted on the side of the drying box 1, and a worm gear 45 is mounted on the fixed rod 43, the worm gear 45 is meshed with a worm 44 for transmission, the worm 44 is mounted on the drive shaft of the first motor 40, and the first motor 40 is mounted on the side of the drying box 1.

[0057] Furthermore, the U-shaped tube drying assembly 5 includes a U-shaped tube 50, the left end of the U-shaped tube 50 is an air inlet 51, the right end of the U-shaped tube 50 is an air outlet 52, a fan 54 and a heating wire 55 are installed in the left end of the U-shaped tube 50, an air outlet groove 53 is opened at the bottom of the middle tube body of the U-shaped tube 50, and the front and rear sides of the air outlet groove 53 are provided with air guide baffles fixed to the U-shaped tube 50, the left end of the U-shaped tube 51 extends to the top of the drying box 1 and is located on the left side of the feeding hopper 2, and the right end of the U-shaped tube 51 extends to the top of the drying box 1 and is located on the right side of the feeding hopper 2.

[0058] When the fan 54 in the U-tube drying assembly 5 is driven, external air is sent into the U-tube 50. The airflow is heated by the electric heating wire 55 to form a hot airflow, which then enters the drying box 1 from the air outlet slot 53, thereby performing wind-driven drying on the edible fungi inside.

[0059] Further, the steam pipe assembly 7 includes a steam pipe 70 connected to the steam equipment, and the output end of the steam pipe 70 is connected to the three-way sleeve 71;

[0060] The toggle drying assembly 6 includes a guide tube 61 which is rotatably mounted inside the drying box 1 and is arranged transversely. A second motor 60 is installed outside the drying box 1. The driving shaft of the second motor 60 is fixedly mounted on the left end of the guide tube 61. The left end of the guide tube 61 is rotatably mounted on a three-way sleeve 71. A plurality of air inlets 610 are opened at the left end of the guide tube 61. The three-way sleeve 71 is wrapped around the left end of the guide tube 61, and the air inlets 610 are all located on the inner side of the three-way sleeve 71.

[0061] A plurality of fixed air pipes 62 and movable air pipes 63 are installed at equal intervals on the guide pipe 61 inside the drying box 1, and the fixed air pipes 62 and the movable air pipes 63 are arranged at intervals, and the ends of the fixed air pipes 62 are open and air holes are opened through the pipe wall;

[0062] The movable air pipes 63 each include a movable pipe body 630, and air holes are formed on the wall of the movable pipe body 630. One section of each movable pipe body 630 is radially rotatably mounted with the guide pipe 61 through a rotating sleeve 632. A paddle plate 66 is fixed to the other end of the plurality of movable pipe bodies 630. The paddle plate 66 is in frictional contact with the inner wall of the bottom semicircular box of the drying box 1. A bevel gear 631 is fixed to the upper part of the movable pipe body 630.

[0063] A plurality of bevel gear rings 64 are fixedly mounted inside the drying box 1 through a fixing rod 65, and the bevel gear rings 64 are meshed with the bevel gears 631 on the movable tube body 630;

[0064] A plurality of elastic paddle components 633 are movably disposed on the movable tube body 630 .

[0065] The steam device, as a steam source, transports steam to the steam pipe 70, and the steam then enters the three-way sleeve 71 from the steam pipe 70. After entering the three-way sleeve 71, the steam enters the interior of the guide pipe 61 from the air inlet 610, flows in the guide pipe 61 and is transported to the fixed air pipe 62 and the movable air pipe 63, and then flows out from the air holes of the fixed air pipe 62 and the movable air pipe 63, and is used for steam drying of edible fungi; since the guide pipe 61 is also connected to the driving shaft of the second motor 60, the second motor 60 can drive the guide pipe 61, the fixed air pipe 62 and the movable air pipe 63 to rotate simultaneously, and the fixed air pipe 62 and the movable air pipe 63 are both used for turning and steam drying of edible fungi;

[0066] The bevel gear 631 disposed on the movable tube body 630 in the movable air pipe 63 meshes with the bevel gear ring 64 for transmission. Therefore, the movable tube body 630 can step and rotate along with the guide tube 61 and can also rotate by itself. During the rotation, the elastic paddle assembly 633 on its surface pokes the edible fungi.

[0067] Furthermore, the elastic paddle assemblies 633 each include a rotating shaft 6330 radially rotatably mounted with the movable tube body 630, a retaining ring 6332 is fixed to one end of the rotating shaft 6330 close to the movable tube body 630, a sleeve 6333 is fixedly sleeved on the other end of the rotating shaft 6330, a paddle 6331 is rotatably mounted on the rotating shaft 6330, and the paddle 6331 is located between the sleeve 6333 and the retaining ring 6332, a torsion spring 6334 is also sleeved on one end of the rotating shaft 6330 located in the sleeve 6333, one end of the torsion spring 6334 is fixed to the inner wall of the sleeve 6333 away from the paddle 6331, and the other end of the torsion spring 6334 is fixed to the end of the paddle 6331 close to the sleeve 6333.

[0068] When the paddle 6331 in the elastic paddle assembly 633 rotates with the movable tube body 630, it encounters resistance from the edible fungi, so that the paddle 6331 can rotate relative to the rotating shaft 6330. However, since the paddle 6331 is connected to the torsion spring 6334, it does not continuously rotate in the same direction, but rather rotates back and forth intermittently. The purpose is to better flip the edible fungi and maintain a sufficient but not excessive force on the edible fungi, thereby avoiding damage to the edible fungi and reducing the breakage rate of the edible fungi.

[0069] After the above-mentioned steam drying and the toggling turning, the drying efficiency of the edible fungi is improved, and the toggling plates 66 installed together at the ends of the multiple movable tube bodies 630 can also be used to clean the inner wall of the bottom of the drying box 1 by friction, which can not only better discharge the materials during discharge, but also turn over and clean up impurities such as debris and soil, so that the impurities can fall from the sieve holes 12 into the collecting box 8.

[0070] Furthermore, a partition 80 is fixed inside the aggregate box 8, and a fungus collecting chamber and a waste collecting chamber are separated by the partition 80. A fungus collecting port 9 is opened on the outside of the aggregate box 8 at a position corresponding to the fungus collecting chamber, and a waste collecting port 10 is opened on the outside of the aggregate box 8 at a position corresponding to the waste collecting chamber.

[0071] The dried edible fungi can fall into the fungi collection chamber of the collection box 8, while the impurities fall from the sieve holes 12 to the waste collection chamber of the collection box 8. The above operation can achieve the separation of the edible fungi and the impurities.

[0072] Furthermore, the dual-purpose discharge assembly 11 includes a first screw conveyor 111 and a second screw conveyor 112. A third motor 110 is installed on the outside of the aggregate box 8. The drive shaft of the third motor 110 is fixedly installed on the left end of the first screw conveyor 111. The right ends of the first screw conveyor 111 and the second screw conveyor 112 both extend to the outside of the aggregate box 8 and are connected through a pulley assembly 113.

[0073] Further, the first screw conveyor 111 and the second screw conveyor 112 each include a rotating shaft and a spiral blade mounted on the rotating shaft;

[0074] The pulley assembly 113 includes a driving wheel, a driven wheel and a belt. The driving wheel is installed at the right end of the first screw conveyor 111, and the driven wheel is installed at the right end of the second screw conveyor 112. The belt is mounted on both the driving wheel and the driven wheel.

[0075] When discharging edible fungi and impurities, the third motor 110 is used to drive the first screw conveyor 111 to rotate. The first screw conveyor 111 and the second screw conveyor 112 are connected by a pulley assembly 113, so that the second screw conveyor 112 can be driven at the same time. The first screw conveyor 111 is used for discharging edible fungi and discharging them from the fungus collection port 9, and the second screw conveyor 112 is used for discharging impurities and discharging them from the waste collection port 10. At this point, the drying of edible fungi, as well as the screening and discharging operations of impurities can be completed.

[0076] A method for drying edible fungi, the method comprising the following steps:

[0077] Step 1: placing the edible fungi; placing the edible fungi to be dried from the feeding hopper 2 into the drying box 1 by manual feeding or mechanical feeding, and the edible fungi falling into the drying box 1 wait for drying treatment;

[0078] Step 2: Drying of edible fungi; using the U-tube drying assembly 5, the steam pipe assembly 7 and the toggle drying assembly 6 alone or simultaneously to dry the edible fungi put into the drying oven 1, wherein:

[0079] The U-shaped tube drying assembly 5 adopts a wind drying method. The fan 54 and the electric heating wire 55 provided inside the air inlet 51 of the U-shaped tube 50 cooperate with each other to draw the external air into the U-shaped tube 50 and heat the electric heating wire 55 to form a hot air flow. The hot air flow enters the drying box 1 from the air outlet slot 53 to perform wind drying on the edible fungi inside.

[0080] The steam pipe assembly 7 is a steam drying method, in which steam is fed into the steam pipe 70 through an external steam device, and the steam flows from the steam pipe 70 into the inside of the three-way sleeve 71, and then the steam enters the drying box 1 to steam dry the edible fungi;

[0081] Step 3: Tumbling drying and screening of edible fungi; when the steam equipment delivers steam to the steam pipe assembly 7, the steam cooperates with the toggle drying assembly 6 to steam dry the edible fungi in the drying box 1, and the toggle drying assembly 6 tumbles the edible fungi while drying, thereby increasing the drying efficiency of the edible fungi;

[0082] When turning over, the sieve hole 12 at the bottom of the drying box 1 can remove debris, dirt and other impurities therein, thereby achieving the purpose of screening and removing impurities;

[0083] Step 4: Discharging of edible fungi and collection and discharging of waste; after drying is completed, the switch component 4 drives the discharge door 3 to open, stops the output of steam, and keeps the toggle drying component 6 running. After the discharge door 3 is opened, the edible fungi fall into the fungus collection chamber of the collection box 8 from the door opening, and impurities such as debris and soil fall into the waste collection chamber of the collection box 8 through the sieve hole 12; the collected edible fungi and waste are discharged simultaneously through the dual-purpose discharge component 11, the edible fungi are collected from the fungus collection port 9, and the waste is collected from the waste collection port 10.
