Description

Technical Field

[0001] This application relates to the field of primary processing technology of edible fungi, and in particular to a drying device for processing edible fungi. Background Technology

[0002] In the processing of edible fungi, the drying process is a crucial step in improving the quality and extending the shelf life of the fungi. Currently, common edible fungi drying equipment on the market typically uses a multi-layer tray structure. After the fungi are placed on the trays, the trays are then placed into the drying chamber from top to bottom for drying. The original intention of this design was to make full use of the space in the drying chamber and improve drying efficiency.

[0003] However, in actual operation, because the trays are distributed in multiple layers inside the drying oven, when there are too many trays, the environment of the trays in different positions varies significantly. Trays closer to the heat source receive more direct and intense heating, while trays farther away from the heat source experience relatively weaker heat transfer. This results in different temperatures experienced by the edible fungi in trays of different heights, leading to deviations in the drying process. Furthermore, since edible fungi are often placed in large quantities on trays, stacking is inevitable. Stacked edible fungi have different levels of air contact between the inside and outside. The outer edible fungi are in direct contact with the hot air, resulting in faster moisture evaporation and easier drying to the required standard in a short time; while the inner edible fungi, blocked by the outer fungi, experience poor hot air circulation, resulting in slow moisture evaporation and delayed drying.

[0004] This results in some edible fungi losing nutrients, becoming less attractive and harder in texture due to excessive heat, and experiencing a significant drop in quality; while other edible fungi, due to insufficient drying, still retain a lot of moisture.

[0005] To address the above problems, a drying device for edible fungi processing has been designed. Utility Model Content

[0006] This application provides a drying device for edible fungi processing to solve the problem that edible fungi drying devices in related technologies typically adopt a multi-layer tray structure. Since the trays are distributed in multiple layers in the drying chamber, when there are too many trays, the trays located in different positions are heated unevenly, resulting in uneven drying of edible fungi and affecting quality.

[0007] In a first aspect, a drying device for processing edible fungi is provided, comprising:

[0008] A drying oven, which has a drying chamber inside for drying edible fungi;

[0009] The hot air unit includes a heater arranged on the back of the drying chamber for heating air. The heater is provided with an air supply pipe that is connected to the drying chamber for sending the heated air into the drying chamber.

[0010] An extraction unit, which is connected to the drying chamber, is used to extract moisture from inside the drying chamber.

[0011] The drying oven has multiple rotating frames arranged from top to bottom inside, and multiple clamping platforms arranged from top to bottom inside the rotating frames. A tray is inserted in the middle of the clamping platform. The tray is used to place edible fungi. The drying oven is equipped with a rotating component, which is used to drive the rotating frames to rotate.

[0012] The clamping platform includes a support net disposed inside the rotating frame, a drag net arranged above the support net, and four elastic support members disposed inside the rotating frame. The four elastic support members are disposed at the four corners of the top of the drag net and provide elastic support to the drag net.

[0013] The tray is inserted between the trawl net and the support net, both of which are metal mesh panels.

[0014] In some embodiments, the rotating frame includes four rotating seats disposed inside the drying chamber. The four rotating seats are arranged in a rectangular pattern, and a disc is rotatably disposed on the top of two rotating seats on the same side. Multiple fixing plates are disposed opposite each other on the disc from top to bottom.

[0015] The trawl net is positioned between four fixed plates at the same height, and the elastic support is positioned on the corresponding fixed plate.

[0016] In some embodiments, the rotating seat includes a fixed plate disposed inside the drying chamber, two bearing seats are disposed opposite each other on the fixed plate, a rotating shaft is rotatably disposed between two adjacent bearing seats, a drag ring is disposed on the rotating shaft, and the drag ring has a groove that slides with the disc.

[0017] In some embodiments, the elastic support includes a cylinder disposed on a fixed plate, the cylinder having an internal cavity and an open bottom;

[0018] A spring is installed inside the cylinder, and a telescopic column is installed at the bottom end of the spring. The bottom end of the telescopic column extends outward and is connected to the trawl net.

[0019] In some embodiments, the pallet is formed by a bottom mesh panel and four side mesh panels. A pull ring is provided on one side of the side mesh panel, and two positioning plates are arranged opposite each other on the other side of the side mesh panel. One side of the positioning plate is in contact with the corresponding support mesh and the trawl net.

[0020] In some embodiments, the rotating component includes a housing disposed on a drying oven, a plurality of rotating shafts rotatably disposed inside the housing, one end of each rotating shaft being connected to a corresponding disc, a drive motor and a reducer being disposed on the housing, the output shaft of the drive motor being connected to the input shaft of the reducer, and the output shaft of the reducer being connected to the other end of any rotating shaft;

[0021] The shaft is equipped with pulleys, and adjacent pulleys are driven by belts.

[0022] In some embodiments, the heater includes a housing, inside which a metal filter and a plurality of electric heating elements are arranged in sequence, and a fan is provided on one side of the housing, with the fan inlet communicating with the housing;

[0023] The air supply pipeline includes multiple air supply pipes connected to the housing. A transfer pipe is connected to each air supply pipe. The transfer pipe and the air supply pipe are arranged perpendicularly. Multiple branch pipes are provided on the transfer pipe. The other end of each branch pipe is connected to the drying chamber. The multiple branch pipes are distributed at equal distances along the length and height of the drying chamber.

[0024] In some embodiments, the extraction unit includes a plurality of fans embedded above the drying chamber, the fans being in communication with the drying chamber for extracting gas from inside the drying chamber.

[0025] This application provides a drying device for edible fungi processing. The rotating frame is controlled by a rotating component, which causes the edible fungi in the tray to continuously change position and angle during the drying process. This avoids the problem of uneven drying caused by the fixed position of the tray in traditional drying equipment. Furthermore, the edible fungi can be turned over inside the rotating tray, so that each edible fungi can fully contact the hot air, ensuring consistent drying effect, reducing the occurrence of over-drying or under-drying of some edible fungi, and improving the overall drying quality of edible fungi.

[0026] The support mesh and drag net in the clamping platform are both made of metal mesh, providing excellent ventilation. The tray is inserted between the two, allowing hot air to penetrate freely and act on the edible fungi from the bottom and sides, greatly improving the utilization rate of hot air and drying efficiency. At the same time, the high structural strength of the metal mesh can withstand the weight of the edible fungi and the tray, ensuring the stability of the equipment operation.

[0027] The heater and air supply pipes can evenly distribute the heated air to every corner of the drying chamber, avoiding localized excessively high or low temperatures. This uniform hot air distribution further ensures the uniformity of edible fungi drying and improves the drying quality. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] This application provides a drying device for edible fungi processing, which can solve the problem that edible fungi drying devices in related technologies usually adopt a multi-layer tray structure. Since the trays are distributed in multiple layers in the drying box, when there are too many trays, the trays located in different positions are heated unevenly, resulting in uneven drying of edible fungi and affecting quality.

[0039] Please see Figures 1-3 A drying device for edible fungi processing includes: a drying box 1, which has a drying chamber 2 for drying edible fungi inside; a hot air unit 3, which includes a heater 31 arranged on the back of the drying box 1, the heater 31 being used to heat air, the heater 31 being provided with an air supply pipe 32, the air supply pipe 32 being connected to the drying chamber 2, for sending the heated air into the drying chamber 2; an exhaust unit 4, which is connected to the drying chamber 2 for extracting moisture from inside the drying chamber 2; and multiple rotating racks 5 arranged from top to bottom inside the drying box 1, the rotating racks 5 having internal structures arranged from top to bottom... The drying chamber 1 is equipped with multiple clamping platforms 6, with a tray 7 inserted in the middle of each clamping platform 6. The tray 7 is used to place edible fungi. A rotating component 8 is provided on the drying chamber 1 to drive the rotating frame 5 to rotate. The clamping platform 6 includes a support net 61 disposed inside the rotating frame 5, a drag net 62 arranged above the support net 61, and four elastic support members 63 disposed inside the rotating frame 5. The four elastic support members 63 are located at the four corners of the top of the drag net 62 and provide elastic support to the drag net 62. The tray 7 is inserted between the drag net 62 and the support net 61. Both the support net 61 and the drag net 62 are metal mesh plates.

[0040] Heater 31 is located on the back of drying chamber 1. When the equipment is started, heater 31 starts to work and heats the incoming air. The heated air is then sent into drying chamber 2 through air supply pipe 32.

[0041] Edible fungi are placed in tray 7, and support net 61 is fixed inside the rotating frame 5 to provide bottom support for tray 7. Tray net 62 is arranged above support net 61, and four elastic support members 63 are set at the four corners of the top of tray net 62 to provide elastic support for tray net 62. When tray 7 is inserted between tray net 62 and support net 61, tray net 62 can fit tightly against tray 7 under the action of elastic support members 63, preventing tray 7 from shaking during rotation, while not affecting the circulation of hot air.

[0042] The rotating component 8 is activated, causing the entire rotating frame 5 to rotate. The multiple clamping platforms 6 inside the rotating frame 5 and the trays 7 inserted into the clamping platforms 6 rotate together, causing the edible fungi in the trays 7 to continuously change position and angle during the drying process, ensuring full contact with the hot air.

[0043] During the drying process, the moisture in the edible fungi evaporates due to heat, forming humid air. The exhaust unit 4 is connected to the drying chamber 2 and continuously extracts the humid air from the drying chamber 2, maintaining a low humidity environment inside the drying chamber 2 and accelerating the drying process of the edible fungi.

[0044] The rotating frame 5 is driven to rotate by the rotating component 8, so that the edible fungi in the tray 7 continuously change position and angle during the drying process. This avoids the problem of uneven drying caused by the fixed position of the tray in traditional drying equipment. In addition, the edible fungi can be turned over inside the rotating tray 7 to prevent them from piling up. This ensures that each edible fungi can fully contact the hot air, ensuring consistent drying effect and reducing the occurrence of over-drying or under-drying of some edible fungi, thereby improving the overall drying quality of the edible fungi.

[0045] The support mesh 61 and the drag mesh 62 in the clamping platform 6 are both metal mesh panels with good ventilation. The tray 7 is inserted between the two, allowing hot air to penetrate freely and act on the edible fungi from the bottom and sides, greatly improving the utilization rate of hot air and drying efficiency. At the same time, the high structural strength of the metal mesh panels can withstand the weight of the edible fungi and the tray 7, ensuring the stability of the equipment operation.

[0046] The heater 31 and the air supply pipe 32 can evenly distribute the heated air to every corner of the drying chamber 2, avoiding local temperatures that are too high or too low. This uniform hot air distribution further ensures the uniformity of the drying of edible fungi and improves the drying quality.

[0047] Understandably, the drying chamber 2 has an opening on one side, with a hinged double door at the opening for loading and unloading edible fungi.

[0048] like Figure 3 and Figure 4As shown, specifically, the rotating frame 5 in this embodiment includes four rotating seats 51 disposed inside the drying chamber 2. The four rotating seats 51 are arranged in a rectangular shape. A disc 52 is rotatably disposed on the top of two rotating seats 51 on the same side. Multiple fixing plates 53 are disposed opposite each other from top to bottom on the disc 52. The drag net 62 is disposed between the four fixing plates 53 at the same height. The elastic support member 63 is disposed on the corresponding fixing plate 53.

[0049] The four rotating seats 51 are arranged in a rectangular pattern inside the drying chamber 2. The distribution of the four vertices of the rectangle can maximize the distribution of the weight of the rotating frame 5 and the trays 7 and edible fungi it carries, providing a stable support foundation for the rotating frame 5. The rotating seats 51 are fixedly connected to the side wall of the drying chamber 2 to ensure that they will not shift or loosen during equipment operation.

[0050] Multiple fixing plates 53 arranged opposite each other from top to bottom on the disc 52 provide installation positions for the trawl net 62 and the elastic support 63. The two fixing plates 53 on the left and right discs 52 are fixed at the same height by bolts to ensure that the four fixing plates 53 at the same height are on the same horizontal plane, thereby ensuring that the trawl net 62 remains horizontal after installation, which is conducive to the stable placement of the tray 7.

[0051] The elastic support 63 is set on the corresponding fixing piece 53, and its bottom is connected to the four top corners of the trawl net 62.

[0052] like Figure 4 As shown, further, the rotating seat 51 in this embodiment includes a fixed plate disposed inside the drying chamber 2. Two bearing seats are disposed opposite to each other on the fixed plate. A rotating shaft is rotatably disposed between two adjacent bearing seats. A drag ring is disposed on the rotating shaft. The drag ring has a groove that slides with the disc 52.

[0053] The fixed plate in the rotating seat 51 supports the entire rotating seat 51 and the disk 52.

[0054] Two bearing seats positioned opposite each other on the fixed plate provide stable support and rotational guidance for the rotating shaft. The bearings inside the bearing seats reduce friction during shaft rotation, making the shaft rotate more smoothly. The groove on the drag ring slides into the disc 52, providing rotational support for the disc 52 and maintaining the stability of its rotation.

[0055] like Figure 4 and Figure 5 As shown, in one embodiment, the elastic support 63 includes a cylinder 531 disposed on the fixing plate 53, the cylinder 531 having a cavity inside and an open bottom;

[0056] A spring 532 is provided inside the cylinder 531, and a telescopic column 533 is provided at the bottom end of the spring 532. The bottom end of the telescopic column 533 extends outward and is connected to the trawl net 62.

[0057] When the tray 7 is not in place, the elastic support 63 is in its naturally extended state. At this time, under the elastic force of the spring 532, the telescopic column 533 partially extends out of the internal cavity of the cylinder 531. Supported by the telescopic column 533, the net 62 maintains a certain distance from the support net 61 below, leaving enough space for the insertion of the tray 7. The spring 532 is in a relatively relaxed but elastic state, ready to withstand external forces at any time.

[0058] When the operator inserts the tray 7 containing edible fungi between the trawl net 62 and the support net 61, the tray 7 applies upward pressure to the trawl net 62. The trawl net 62 transmits this pressure to the telescopic column 533. After receiving the upward force, the telescopic column 533 begins to compress the spring 532 and retracts into the cavity inside the cylinder 531.

[0059] During compression, the elastic potential energy of spring 532 gradually increases, generating an upward reaction force on telescopic column 533. This reaction force creates a buffering effect, preventing the trawl net 62 and pallet 7 from colliding violently or being damaged due to sudden force. At the same time, it allows the trawl net 62 to smoothly adhere to the upper surface of pallet 7, providing a stable clamping effect on pallet 7.

[0060] When the rotating component 8 drives the rotating frame 5 to start rotating, the tray 7 and the edible fungi inside will be subjected to centrifugal force, resulting in an outward tendency. At this time, the spring 532 in the elastic support component 63 can automatically adjust the position of the telescopic column 533 according to the change of centrifugal force. If the centrifugal force causes the tray 7 to tend to detach upward from the net 62, the elastic force of the spring 532 will cause the telescopic column 533 to extend further, increasing the support force on the net 62 and ensuring that the net 62 always fits tightly against the tray 7, preventing the tray 7 from shaking or shifting. Conversely, if other factors cause the pressure of the tray 7 on the net 62 to suddenly increase, the spring 532 will be further compressed to absorb the excess force, maintain the dynamic balance of the system, and keep the tray 7 stable during rotation.

[0061] like Figure 6 As shown, it should be noted that the pallet 7 is formed by a bottom mesh plate 71 and four side mesh plates 72. A pull ring 73 is provided on one side mesh plate 72, and two positioning plates 74 are provided opposite to each other on the other side mesh plate 72. One side of the positioning plate 74 is in contact with the corresponding support mesh 61 and the drag mesh 62.

[0062] The tray 7 is formed by a bottom mesh plate 71 and four side mesh plates 72, which provide a good flow channel for hot air. During the drying process, the hot air in the drying chamber 2 can penetrate upward from the bottom mesh plate 71 and enter the tray 7 laterally from the mesh openings of each side mesh plate 72, making full contact with the edible fungi and achieving all-round, multi-angle drying, which effectively improves drying efficiency and uniformity.

[0063] When the tray 7 is inserted between the drag net 62 and the support net 61, the two positioning plates 74 on the side mesh plate 72 will contact the support net 61 and the drag net 62 respectively, restricting the movement of the tray 7 in the horizontal direction. This ensures that the tray 7 can be stably maintained between the support net 61 and the drag net 62 during rotation, and will not shift or shake due to centrifugal force or other external forces, thus ensuring the positional stability of the edible fungi during the drying process.

[0064] When placing the tray 7 into the drying chamber 2, the operator can hold the pull ring 73 to smoothly insert the tray 7 into the appropriate position between the drag net 62 and the support net 61. After drying, the tray 7 can also be easily removed from the drying chamber 2 by pulling the pull ring 73, which greatly improves the convenience and efficiency of operation and reduces the time and labor intensity of manual operation.

[0065] like Figure 3 and Figure 4 As shown, in one embodiment, the rotating component 8 includes a housing 81 disposed on the drying chamber 1. A plurality of rotating shafts 82 are rotatably disposed inside the housing 81. One end of each rotating shaft 82 is connected to a corresponding disc 52. A drive motor and a reducer are disposed on the housing 81. The output shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the other end of any rotating shaft 82. A pulley 83 is disposed on each rotating shaft 82, and adjacent pulleys 83 are driven by a belt.

[0066] In actual operation, the drive motor runs, and its output shaft rotates according to the set speed and direction. The power generated by the drive motor is transmitted to the reducer. The reducer converts the high-speed, low-torque power output by the drive motor into low-speed, high-torque power through the internal gear transmission mechanism to meet the requirement of driving the rotating frame 5 and the tray 7 to rotate stably.

[0067] Since the output shaft of the reducer is connected to the other end of one of the rotating shafts 82, the power output by the reducer directly acts on the rotating shaft 82, causing it to start rotating. The pulley 83 on it also rotates. Since the belt is tightly wound around two adjacent pulleys 83, it drives another adjacent pulley 83 to rotate. Through this method of sequential transmission between the pulleys 83 and the belt, the power is gradually transmitted from the starting rotating shaft 82 to the other rotating shafts 82, so that the multiple rotating shafts 82 inside the housing 81 can rotate synchronously. The rotation of the rotating shaft 82 drives the disc 52 to rotate synchronously, thereby enabling all the trays 7 on the entire rotating frame 5 to rotate simultaneously and evenly.

[0068] like Figure 7 As shown, in a preferred embodiment, the heater 31 includes a housing 311, inside which a metal filter 312 and a plurality of electric heating elements 313 are arranged in sequence. A fan 314 is arranged on one side of the housing 311, and the air inlet of the fan 314 is connected to the housing 311. The air supply pipe 32 includes a plurality of air supply pipes 321 connected to the housing 311. A transfer pipe 322 is connected to the air supply pipe 321. The transfer pipe 322 and the air supply pipe 321 are arranged perpendicularly. A plurality of diversion pipes 323 are arranged on the transfer pipe 322. The other end of the diversion pipe 323 is connected to the drying chamber 2. The plurality of diversion pipes 323 are distributed at equal intervals along the length and height of the drying chamber 2.

[0069] After the fan 314 is started, it will create a negative pressure in the housing 311, causing outside air to enter through the air inlet of the housing 311. The air is first filtered by the metal filter screen 312, which performs preliminary purification of the air entering the heating area to prevent these impurities from entering the subsequent equipment or the drying chamber 2, and to avoid damaging the electric heating element 313 or contaminating the dried products.

[0070] The filtered air continues to flow, and the electric heating element 313 generates heat when energized, transferring the heat to the surrounding air through thermal conduction. As air continues to flow through the electric heating element 313, the air temperature gradually rises, thus forming hot air. The arrangement of multiple electric heating elements 313 increases the contact area between the air and the heat source, improves heating efficiency, and ensures that the generated hot air temperature meets the requirements for drying edible fungi.

[0071] Under the continuous action of the fan 314, the generated hot air enters multiple air supply pipes 321 from the air outlet of the housing 311. The air supply pipes 321 are vertically connected to the transfer pipes 322. After the hot air reaches the end of the air supply pipes 321, multiple diversion pipes 323 further divert the hot air. Since the multiple diversion pipes 323 are distributed at equal distances along the length and height of the drying chamber 2, the hot air can enter the drying chamber 2 evenly from different positions and heights, ensuring that each area in the drying chamber 2 can obtain sufficient hot air supply and avoiding local temperature problems such as excessively high or low temperatures.

[0072] Multiple diversion pipes 323 are distributed at equal intervals along the length and height of the drying chamber 2, so that the hot air can be evenly distributed in the drying chamber 2. The uniform hot air distribution allows the edible fungi in all positions in the drying chamber 2 to be heated simultaneously and evenly, thereby ensuring that each batch of edible fungi can achieve similar drying effects during the drying process, and improving the stability and consistency of the quality of the dried products.

[0073] like Figure 1 and Figure 3 As shown, specifically, the air extraction unit 4 includes multiple fans 41 embedded above the drying chamber 1. The fans 41 are connected to the drying chamber 2 and are used to extract the gas inside the drying chamber 2.

[0074] When the drying equipment starts running for a period of time, a large amount of hot air is generated in the drying chamber 2 due to the operation of the heater 31. The moisture of the edible fungi evaporates due to the heat, and the indoor humidity and the concentration of some volatile substances increase.

[0075] At this time, multiple fans 41 in the extraction unit 4 start operating. Driven by the motor, the fan blades of the fans 41 rotate at high speed, creating a negative pressure environment inside the drying chamber 2. The rotation of the fans 41 increases the airflow velocity near the fan blades and reduces the pressure, thus creating a pressure difference with the relatively high pressure inside the drying chamber 2. Under the influence of this pressure difference, the gas inside the drying chamber 2 begins to flow towards the location of the fans 41. Since the fans 41 are embedded above the drying box 1 and communicate with the drying chamber 2, the gas is extracted from the drying chamber 2 through the fans 41.

[0076] In the overall operation of the drying equipment, the extraction unit 4, along with the heater 31, air supply pipe 32, and other components, constitute a hot air circulation system. The extraction unit 4 continuously extracts waste gas and moisture from the drying chamber 2, while the heater 31 continuously generates hot air and delivers it to the drying chamber 2 through the air supply pipe 32, forming a dynamic balance. This circulation mechanism ensures that the hot air in the drying chamber 2 maintains suitable temperature, humidity, and cleanliness, allowing edible fungi to be dried in a stable environment, thus improving drying efficiency and quality.

[0077] In one embodiment, the device is used to dry bamboo fungus, and the specific temperature and time operation are as follows:

[0078] First stage (low temperature setting): Temperature control: 40℃~45℃, drying time: 2~3 hours. The low temperature environment promotes the slow evaporation of moisture on the surface of bamboo fungus, avoids the hardening of the surface of the fungus and the retention of internal moisture due to high temperature, and at the same time reduces the risk of darkening of color.

[0079] The second stage (high-temperature dehydration): Temperature control: 50℃~60℃, drying time: 1.5~4 hours. The internal moisture is evaporated by moderately increasing the temperature. A strong dehumidification system is required to prevent condensation from accumulating. This stage is the critical period for dehydration efficiency.

[0080] The third stage (low temperature slow drying): control the temperature at 40℃~50℃ and the drying time at 2~3 hours. By lowering the temperature, the bacteria are prevented from becoming brittle, while the residual moisture is dried slowly to ensure that the moisture content meets the standard and the bacteria remain intact.

[0081] Fourth stage (re-drying stage): Temperature control: 45℃~50℃, drying time: 1~2 hours (adjusted according to moisture content).

[0082] In practice, after the main drying is completed, the machine needs to be left to stand overnight to rehydrate, and then dried again the next day to ensure that the moisture content is stable in the range of 10% to 13%.
