Description

Technical Field

[0001] This application relates to the technical field of edible mushroom drying and screening equipment, and particularly to a drying and screening equipment for edible mushroom processing. Background Art

[0002] Edible mushrooms refer to fleshy, edible fungi (macrofungi) with large fruiting bodies, commonly known as mushrooms. Edible mushrooms are rich in nutrients such as protein, fungal polysaccharides, dietary fiber, vitamins, and trace elements. The fungal polysaccharides of many edible mushrooms have immunomodulatory effects, which can enhance the phagocytic function of the reticuloendothelial system. By acting on lymphocytes, macrophages, the reticuloendothelial system, etc., they can improve and regulate the body's immune function, and have high economic benefits. In the processing of edible mushrooms, drying and screening are important links in the edible mushroom industrial chain, directly affecting the product quality, storage time, and added value.

[0003] Existing edible mushrooms are generally dried by hot air and screened using a sieve mesh. To improve processing efficiency, drying and screening are carried out simultaneously. For example, the Chinese utility model patent with the publication number CN221729665U discloses an integrated device for grading, screening, and drying edible mushrooms, belonging to the technical field of edible mushroom processing. It includes a processing box, a screening frame, and a screening mesh. Opposite side walls of the processing box are respectively provided with a plurality of chutes located at both ends of the corresponding screening frame, and each screening frame is reciprocally slidably arranged in the corresponding chute. The top of the processing box is provided with a feeding port, and a air supply assembly is arranged on the top of the processing box. The screening frame can be driven to reciprocally move through a driving assembly, so as to grade and screen the edible mushrooms, and cooperate with the air supply assembly to dry and process the screened edible mushrooms.

[0004] However, screening is carried out through the upper and lower arranged screening meshes, which makes it easy for the edible mushrooms to get stuck in the mesh holes of the sieve mesh, affecting the subsequent screening efficiency.

[0005] The Chinese invention patent with the publication number CN118808122A discloses an anti-blocking drying and screening equipment for edible mushrooms, which relates to the technical field of edible mushroom processing. The equipment includes a screening belt and an annular conveyor belt. Both ends of a plurality of the screening belts are respectively arranged on a same driving roller and a first driving roller. A plurality of limiting wheels are tightly arranged on the inner side of the annular conveyor belt. Friction belts are fixedly arranged at both ends of the outer side of the annular conveyor belt, and driving wheels are tightly arranged on the friction belts. A drying assembly is arranged at the upper end of the first connecting side plate. A lifting mechanism is arranged on the inner side of the annular conveyor belt, and a screening mechanism is arranged on the inner side of the annular conveyor belt. In the present invention, by providing a screening plate and a third material guiding plate, it is convenient to screen and separately collect the waste materials. Through the combined use of a friction wheel, a friction plate, a stop frame, and a guide rod, it is convenient to automatically clean the lifting plate. By providing a cleaning pipe and a transmission pipe, it is convenient to clean the annular conveyor belt.

[0006] Although it uses the hot air flow of drying to clean the filter holes on the annular conveyor belt, the filter hole diameters of the annular conveyor belt are the same. It can only perform single screening, which affects the screening efficiency. Moreover, its cleaning pipe is always closely attached to the annular conveyor belt, which leads to the frictional resistance that needs to be overcome when the annular conveyor belt is driven, resulting in increased energy consumption. Summary of the Invention

[0007] The present application proposes a drying and screening device for edible mushroom processing, which has the advantages of simultaneously drying and screening edible mushrooms, and high processing efficiency and good effect, so as to solve the problems of low processing efficiency and poor effect when the existing devices simultaneously perform drying and screening processing on edible mushrooms.

[0008] To achieve the above object, the present application adopts the following technical solution: A drying and screening device for edible mushroom processing, including a box body, wherein an inclined rotary screening device is arranged inside the box body, and the rotary screening device includes a first screening component, a second screening component, and a third screening component arranged in sequence from the inside to the outside.

[0009] The first screening component includes a first screen, the first screen is driven to rotate by a rotary driving motor arranged inside the box body, and further includes a first envelope extending outside the second screening component, and a first material groove is opened on the first envelope. A feeding device is also arranged inside the box body, and one end of the feeding device extends into the first screen.

[0010] The second screening component includes a second screen, the second screen rotates synchronously with the positioning rotating pipe, and a second envelope extending outside the third screening component is arranged on one side of the second screen, and a second material groove is opened on the second envelope.

[0011] The third screening component includes a third side plate, the third screen rotates synchronously with the positioning rotating pipe, and a third sealing sleeve is further arranged on one side of the third screen, and a third material groove is opened on the third sealing sleeve.

[0012] An air flow drying device is also arranged inside the box body, a cylinder for driving the air flow drying device to move longitudinally is arranged on the top of the box body, the air flow drying device includes three air flow output pipes respectively arranged directly above the first screen, the second screen, and the third screen, and a gas guiding groove communicating with the air inlet cavity is opened at the bottom of the air flow output pipe.

[0013] By sequentially arranging a first sieve mesh, a second sieve mesh, and a third sieve mesh with different apertures from the inside out, and driving the first sieve mesh, the second sieve mesh, and the third sieve mesh to rotate synchronously by a rotary drum drive motor, the edible fungi can be sieved three times according to the diameter of the edible fungus caps, obtaining edible fungi with different cap diameters. At the same time, hot air is blown out through the air guide grooves opened at the bottom of the air output pipe to dry the edible fungi being sieved, improving the processing efficiency of the edible fungi. And through the design of the rotary drum type sieving device, the edible fungi are turned over as the first sieve mesh, the second sieve mesh, and the third sieve mesh rotate, which is beneficial to the hot air acting on the surface of the edible fungi, improving the drying effect of the edible fungi, avoiding the problem that the local part of the edible fungi is not fully dried due to accumulation. And since the air output pipe is driven by a cylinder and can move longitudinally to adjust the distance between the air output pipe and the surfaces of the first sieve mesh, the second sieve mesh, and the third sieve mesh. During the normal sieving stage, the air output pipe is kept separated from the first sieve mesh, the second sieve mesh, and the third sieve mesh, avoiding the problem of increased energy consumption caused by overcoming frictional resistance. And by actively controlling the cylinder to drive the air output pipe to move downwards, after the three air output pipes are respectively attached to the surfaces of the first sieve mesh, the second sieve mesh, and the third sieve mesh, the edible fungi stuck in the mesh holes of the first sieve mesh, the second sieve mesh, and the third sieve mesh can be blown off by the hot air flows blown out by the three air output pipes, ensuring the permeability of the mesh holes of the first sieve mesh, the second sieve mesh, and the third sieve mesh, and thus enabling the sieving and processing of the edible fungi to proceed continuously and efficiently.

[0014] Further, a support plate and a support sleeve are fixedly installed inside the box body. The first screening assembly further includes two positioning rotating pipes, which are respectively installed on the support plate and the support sleeve through bearings. A first belt pulley located outside the support plate is fixedly installed on one of the positioning rotating pipes. A second belt pulley is fixedly sleeved on the output rotating shaft of the rotating cylinder driving motor. The second belt pulley is connected to the first belt pulley through belt drive. The first screening assembly is supported at both ends by the support plate and the support sleeve. The output rotating shaft driven by the rotating cylinder driving motor drives the second belt pulley to rotate. The second belt pulley drives the first belt pulley and the positioning rotating pipe to rotate through the belt drive, thereby driving the entire first screening assembly to rotate. Cooperating with the inclined setting of the rotating cylinder type screening device, the edible fungi in the positioning rotating pipe are screened as the positioning rotating pipe rotates and move to the other end of the first screening assembly for collection. Three connecting sleeves are fixedly installed on the side of the support plate. The three connecting sleeves are respectively connected to a first side plate in the first screening assembly, a second side plate in the second screening assembly, and a third side plate in the third screening assembly through bearings. And guide covers are respectively fixedly installed on the sides of the three connecting sleeves on both sides of the air flow output pipe. The inner sides of the three guide covers are respectively close to the outside of the third screen, the second screen, and the first screen without contact. By using the diversion setting of the three guide covers on the sides of the support plate and the support sleeve, the hot air ejected from the air flow output pipe above the third screen, the second screen, and the first screen can respectively blow to the bottom of their respective inner cavities, so as to simultaneously dry the edible fungi being screened at the bottom of the inner cavities of the third screen, the second screen, and the first screen, improving the overall drying effect of the edible fungi. And by using the blocking of the guide cover, it is prevented that during the back blowing stage, the screened edible fungi fall back into the second screen or the first screen. Chutes for movably sleeving the air guide branch pipes are also opened on the support plate and the support sleeve. By opening the chutes, it does not affect the longitudinal movement of the air guide branch pipes along with the whole air flow drying device.

[0015] Further, first side plates are respectively fixedly installed on the opposite sides of the two positioning rotating pipes. A plurality of first cross plates arranged in a circumferential array are respectively fixedly installed on the opposite sides of the two first side plates, and the first cross plates are arranged in a circumferential array on the side of the first side plate. The first cross plates on one side of the two positioning rotating pipes are fixedly connected through an intermediate linkage device. A plurality of equally spaced first ring plates are fixedly sleeved on the outside of the first cross plates. The first screen is sleeved on the outside of the first ring plates. The rotating cylinder frame is formed by the first side plate, the first cross plate, and the first ring plate, which is convenient for the first screen to be formed into a cylindrical shape, so as to screen the edible fungi by the rotation of the first screen. And by connecting the first screens on both sides through the intermediate linkage device in the middle, the stability of the rotation of the first screen is improved. At the same time, by using the connection of the intermediate linkage device, the first screening assembly can also drive the second screening assembly and the third screening assembly to rotate together.

[0016] Further, the intermediate linkage device includes a first sleeve, a second sleeve, and a third sleeve arranged in sequence from inside to outside, and the first sleeve, the second sleeve, and the third sleeve are fixedly connected by linkage rods. Both sides of the first sleeve are fixedly connected to one ends of first cross plates on one side of two positioning rotating pipes respectively.

[0017] Further, the second screening assembly further includes two second side plates, which are respectively installed on the support plate and the support sleeve through bearings. A number of second cross plates distributed in a circumferential array are fixedly installed on the opposite sides of the two second side plates respectively. One ends of the second cross plates on one side of the two second side plates are fixedly connected to both sides of the second sleeve respectively. A number of second ring plates arranged at equal intervals are fixedly installed on the outer sides of the second cross plates. The second screen is fixedly sleeved on the outer sides of the second ring plates. The second side plates, the second cross plates, and the second ring plates form a rotating cylinder frame, which is convenient for the second screen to be formed into a cylindrical shape, so as to use the rotation of the second screen to screen the edible fungi again. And because both sides of the second sleeve are fixedly connected to the second cross plates, the whole second screening assembly can rotate synchronously with the intermediate linkage device and the first screening assembly.

[0018] Further, the third screening assembly further includes two third side plates, which are respectively installed on the support plate and the support sleeve through bearings. A number of third cross plates distributed in a circumferential array are fixedly installed on the opposite sides of the two third side plates respectively. One ends of the third cross plates on one side of the two third side plates are fixedly connected to both sides of the third sleeve respectively. The third side plates, the third cross plates, and the third ring plates form a rotating cylinder frame, which is convenient for the third screen to be formed into a cylindrical shape, so as to use the rotation of the third screen to screen the edible fungi again. And because both sides of the third sleeve are fixedly connected to the third cross plates, the whole third screening assembly can rotate synchronously with the intermediate linkage device and the first screening assembly.

[0019] Further, an air inlet cavity is provided inside the air flow output pipe, and the air inlet cavity is communicated with the air guide groove. The width value of the air guide groove decreases uniformly from top to bottom. When the hot air enters the air inlet cavity and flows through the air guide groove, the flow rate of the hot air can be increased, which is beneficial to the flow of the hot air in the inner cavities of the first screen, the second screen, and the third screen, thereby improving the drying effect of the edible fungi.

[0020] Further, one ends of three air flow output pipes are respectively fixedly connected with air guide branch pipes, and the ends of the three air guide branch pipes far away from the air flow output pipes are fixedly connected with an air guide main pipe. The inner cavities of the air inlet pipe, the air guide main pipe, the air guide branch pipes, and the air flow output pipes are communicated.

[0021] Furthermore, the air guide branch pipe is a rigid pipe, and the air inlet pipe is a flexible pipe. The two air flow output pipes above the third sieve are fixedly connected through a positioning coupling shaft. Through the design connection of the rigid air guide branch pipe, while providing hot air diversion, when the cylinder drives the piston shaft to drive the air flow output pipe above the third sieve to move longitudinally, it can also stably drive the air flow output pipes above the second sieve and the first sieve to move longitudinally.

[0022] Furthermore, the bottoms of the three air flow output pipes are respectively set as arc surfaces adapted to the outer sides of the third sieve, the second sieve, and the first sieve, so that the three air flow output pipes can respectively fit with the third sieve, the second sieve, and the first sieve, in order to blow off the edible fungi stuck in the mesh holes of the third sieve, the second sieve, and the first sieve by using the hot air for drying the edible fungi.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. A drying and screening device for edible fungi processing provided by the present application can screen edible fungi three times according to the diameter of the caps of edible fungi through the first screening component, the second screening component, and the third screening component arranged in sequence from the inside to the outside, and obtain edible fungi with different cap diameters. Moreover, compared with the existing method of the transverse change of the mesh holes of a single cylindrical sieve, the screening path of the present invention is longer, improving the screening effect of edible fungi.

[0025] 2. By blowing hot air through the air guide grooves opened at the bottoms of the air flow output pipes, the edible fungi being screened are dried, improving the processing efficiency of edible fungi. And through the design of the rotary screening device, the edible fungi are flipped as the first sieve, the second sieve, and the third sieve rotate during the screening of edible fungi, which is beneficial for the hot air to act on the surface of the edible fungi, improving the drying effect of edible fungi and avoiding the problem that the edible fungi are not fully dried locally due to accumulation.

[0026] 3. The three air flow output pipes in the first sieve, the second sieve, and the third sieve can be driven to move longitudinally by a cylinder, adjusting the distance between the air flow output pipes and the surfaces of the first sieve, the second sieve, and the third sieve. During the normal screening stage, the air flow output pipes are kept separated from the first sieve, the second sieve, and the third sieve, avoiding the problem of increased energy consumption caused by overcoming frictional resistance. And by actively controlling the cylinder to drive the air flow output pipes to move downward, after the three air flow output pipes respectively fit onto the surfaces of the first sieve, the second sieve, and the third sieve, the hot air flows blown out by the three air flow output pipes can be used to blow off the edible fungi stuck in the mesh holes of the first sieve, the second sieve, and the third sieve, ensuring the permeability of the mesh holes of the first sieve, the second sieve, and the third sieve, and thus enabling the screening and processing of edible fungi to proceed continuously and efficiently.

[0051] Please refer to Figure 3 、 Figures 8 - 10 On the opposite sides of the support plate 2 and the support sleeve 3, air flow drying devices 11 are respectively installed. The air flow drying device 11 includes three air flow output pipes 111. The three air flow output pipes 111 are respectively located directly above the first screen 406, the second screen 504 and the third screen 604. An air inlet cavity is provided inside the air flow output pipe 111, and an air guide groove communicating with the air inlet cavity is opened at the bottom of the air flow output pipe 111. The width value of the air guide groove decreases uniformly from top to bottom. One ends of the three air flow output pipes 111 are respectively fixedly connected with air guide branch pipes 112. One ends of the three air guide branch pipes 112 far away from the air flow output pipes 111 are fixedly connected with an air guide main pipe 113.

The inner cavities of the air inlet pipe 114, the air guide main pipe 113, the air guide branch pipes 112 and the air flow output pipes 111 are communicated. Hot air is introduced through the air inlet pipe 114. The hot air flows through the air guide main pipe 113 and the air guide branch pipes 112 in sequence and enters the air flow output pipes 111, and flows out from the air guide grooves inside the air flow output pipes 111, and acts on the edible fungi in the third screen 604, the second screen 504 and the first screen 406 respectively, so as to dry the edible fungi.

[0052] A cylinder 12 is fixedly installed on the top of the box body 1. The piston shaft of the cylinder 12 is fixedly connected with the top of the air flow output pipe 111. The air guide branch pipe 112 is a rigid pipe, and the air inlet pipe 114 is a flexible pipe. The bottoms of the three air flow output pipes 111 are respectively set as arc surfaces adapted to the outsides of the third screen 604, the second screen 504 and the first screen 406. By driving the piston shaft to move through the cylinder 12, the air flow output pipes 111 are driven to move longitudinally. In the normal drying stage, the piston shaft is driven by the cylinder 12 to drive the three air flow output pipes 111 to move upward, so that the three air flow output pipes 111 are respectively separated from the outsides of the third screen 604, the second screen 504 and the first cross plate 404, without affecting the rotation of the overall third screening assembly 6, the second screening assembly 5 and the first screening assembly 4 during the screening stage. When it is necessary to clean the edible fungi stuck in the filter holes of the third screen 604, the second screen 504 and the first screen 406, the piston shaft is driven by the cylinder 12 to drive the three air flow output pipes 111 to move downward, so that the three air flow output pipes 111 are respectively attached to the outsides of the third screen 604, the second screen 504 and the first screen 406, and the edible fungi stuck in the filter holes of the third screen 604, the second screen 504 and the first screen 406 are blown off by the drying air flow, so as to solve the problem of edible fungi getting stuck in the screen.

[0053] The two air flow output pipes 111 located above the third screen 604 are fixedly connected through a positioning connecting shaft 14. By connecting the two air flow output pipes 111 through the positioning connecting shaft 14, on the premise of not affecting the rotation of the intermediate linkage device 10, it is convenient for the air flow drying devices 11 on both sides of the intermediate linkage device 10 to move longitudinally stably.

[0054] Please refer to Figures 3 - 12 Figures 3 - 12 , three connecting sleeves 201 are fixedly installed on the side of the support plate 2.

Continuously add the edible fungi that need to be dried and screened to the conveyor belt of the feeding device 8, and start the feeding motor 9 to drive the conveyor belt to transport the edible fungi into the first screening assembly 4. The edible fungi are first screened for the first time by the first screen 406 in the first screening assembly 4. The edible fungi retained in the first screen 406 are discharged and collected through the first trough 408. Then use the second screen 504 in the second screening assembly 5 to conduct the second screening. The edible fungi retained in the second screen 504 are discharged and collected through the second trough 506. Finally, use the third screen 604 in the third screening assembly 6 to conduct the third screening. The edible fungi retained in the third screen 604 are discharged and collected through the third trough 606. When a certain amount of edible fungi are stuck in the mesh holes of the first screen 406, the second screen 504 and the third screen 604, drive the piston shaft of the air cylinder 12 to control the air flow drying device 11 to move downward, so that the three air flow output pipes 111 in the air flow drying device 11 are respectively attached to the surfaces of the third screen 604, the second screen 504 and the first screen 406, and use the hot air flow to blow off the edible fungi stuck in the mesh holes. One side of the bottom of the box body 1 is connected to a hot air return channel (not shown in the figure), which is convenient for the hot air used for drying to flow in the box body 1 and ensures the drying effect.
