Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically an energy-saving edible fungus drying equipment. Background Technology

[0002] Common edible fungi include shiitake mushrooms, oyster mushrooms, enoki mushrooms, king oyster mushrooms, and wood ear mushrooms. They are nutritious foods rich in protein, amino acids, and various trace elements. Fresh edible fungi have a high moisture content of 80%-90%. After harvesting, they are prone to spoilage at room temperature due to enzyme activity and microbial growth. They are also crisp and tender, easily damaged during transportation, and have a short storage period. Drying can reduce the moisture content to below 10%, effectively inhibiting microbial growth and enzymatic reactions, extending the shelf life to more than one year. It also facilitates transportation and subsequent processing, concentrates flavor substances, and increases the added value of the product. Existing drying technologies mainly employ hot air drying equipment, where edible fungi are laid flat or stacked on wire mesh racks or trays, and hot air is generated by electric heating or coal combustion, using natural convection or forced circulation for drying. However, because the edible fungi are stacked and block each other, the hot air has difficulty penetrating the stacked layers. This results in the outer and upper layers of edible fungi being exposed to the hot air first and drying rapidly, even to the point of over-drying, while the inner and lower layers dry slowly due to insufficient heat and airflow. To ensure that the overall drying meets standards, continuous heating is required, leading to energy waste. Furthermore, over-dried areas can affect product quality. Therefore, it is necessary to redesign an energy-efficient edible fungi drying equipment to address these issues. Utility Model Content

Multiple support rods are installed between every two placement frames and between the corresponding placement frames and the bottom plate. A weight detection plate is commonly installed on the top surface of every two corresponding support rods, and each placement frame is installed on the top surface of the corresponding weight detection plate. Multiple [unclear - possibly related to a specific type of support frame] are rotatably connected within each placement frame. The drying chamber has rollers, and the spacing between the rollers in the multiple placement frames decreases sequentially from top to bottom. A vibration mechanism is installed on the side wall of the drying chamber, and the vibration mechanism drives the multiple placement frames and the bottom plate to vibrate reciprocally. A connecting seat is installed on both inner walls of the drying chamber. Multiple inclined air ducts are connected to the outside of each connecting seat, and the opening of each inclined air duct faces the bottom of the corresponding placement frame. An air direction adjustment component is installed in each connecting seat.

[0006] Preferably, each of the wind direction adjustment components includes a fixing plate, and each fixing plate is fixedly installed on the side wall of the corresponding connecting seat. Multiple electric telescopic rods are symmetrically installed on the upper and lower end faces of each fixing plate. The other end of the multiple electric telescopic rods located on the same side is jointly installed with a sealing plate, and the sealing plate is adapted to the opening size of the inclined air duct.

[0007] Preferably, each of the hot air conveying components includes an air supply seat, and each air supply seat is installed on the outside of the drying chamber, and each air supply seat is connected to a corresponding connecting seat. Each air supply seat is equipped with a fan and multiple heating tubes.

[0008] Preferably, the vibration mechanism includes a drive motor, which is mounted on the top surface of the drying chamber. The bottom output shaft of the drive motor passes through the drying chamber and is coaxially connected to a rotating shaft. Multiple cams are mounted on the outer side of the rotating shaft, and the multiple cams abut against the outer side of the corresponding placement frame and collection box.

[0011] Three beneficial effects Compared with the prior art, this utility model provides an energy-saving edible fungus drying equipment, which has the following beneficial effects: 1. This utility model achieves layered drying and dynamic conveying of edible fungi through devices such as a collection box, a placement frame, a base plate, a weight detection plate, a vibration mechanism, a hot air conveying component, a connecting seat, an inclined air duct, an air direction adjustment component, and idlers. The vibration mechanism drives the placement frame to vibrate, so that the edible fungi are evenly distributed and fall through the gaps of the idlers according to the degree of drying. The weight detection plate monitors the quantity and distribution of edible fungi. The air direction adjustment component precisely controls the hot air supply of the inclined air duct to avoid energy waste. At the same time, the collection box efficiently collects the finished product, solving the problems of uneven drying and excessive energy consumption caused by accumulation in traditional drying.

[0012] 2. This utility model achieves efficient discharge of water vapor from the drying chamber through devices such as inclined plates, through holes, and L-shaped guide tubes. The water vapor generated during the drying process flows along the inclined plates, is guided by the L-shaped guide tubes, and is discharged outside the chamber through the through holes. This effectively avoids water vapor accumulation inside the chamber, which would lead to increased humidity, and prevents water vapor condensation and backflow from affecting the drying quality of edible fungi. At the same time, it reduces energy consumption caused by prolonged drying time due to humidity issues and ensures the stability of the drying environment. Attached Figure Description

[0015] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or weight direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0016] This utility model provides a technical solution for an energy-saving edible fungus drying equipment: Please see Figures 1-6 An energy-saving edible fungus drying device includes a drying chamber 1. A bottom plate 8 is slidably connected to the bottom wall of the drying chamber 1. A collection box 10 is installed on the top surface of the bottom plate 8. Multiple placement frames 11 are sequentially installed on the top of the bottom plate 8. Multiple support rods 9 are installed between every two placement frames 11 and between the corresponding placement frame 11 and the bottom plate 8. A weight detection plate 19 is installed on the top surface of every two corresponding support rods 9. Each placement frame 11 is installed on the top surface of the corresponding weight detection plate 19. Multiple idler rollers 20 are rotatably connected inside each placement frame 11. The spacing between the multiple rollers 20 in the multiple placement frames 11 decreases sequentially. A vibration mechanism is installed on the side wall of the drying box 1, and the vibration mechanism drives the multiple placement frames 11 and the bottom plate 8 to vibrate back and forth. A connecting seat 5 is installed on both inner walls of the drying box 1. Multiple inclined air ducts 6 are connected to the outside of each connecting seat 5, and the opening of each inclined air duct 6 faces the bottom of the corresponding placement frame 11. An air direction adjustment component is installed in each connecting seat 5. Hot air conveying components are installed on both outer sides of the drying box 1, and each hot air conveying component is connected to the corresponding connecting seat 5. It should be noted that the initial edible fungi are placed in the top placement frame 11. With the help of the vibration mechanism, the edible fungi in the placement frame 11 can vibrate and change position to make them more uniform. After the edible fungi at the top have dried to a certain stage, their volume decreases. At this time, the edible fungi fall through the gap between the rollers 20 into the placement frame 11 below to continue drying until all the edible fungi have fallen into the collection box 10, thus completing the drying of all the edible fungi. Furthermore, during the drying process, the weight detection plate 19 can detect the weight of the edible fungi in each placement box 11 in real time. It should be noted that the moisture content of the edible fungi is basically the same. Therefore, by measuring the overall weight of the edible fungi in the initial state, a rough net weight of the edible fungi can be obtained. Thus, the weight detection plate 19 can roughly detect the distribution and quantity of edible fungi in the placement box 11. Then, the opening and closing of each inclined air duct 6 and the air volume can be adjusted by the air direction adjustment component to achieve on-demand distribution, which is more energy-efficient and avoids over-drying of the edible fungi.

[0017] Furthermore, each wind direction adjustment component includes a fixing plate 23, and each fixing plate 23 is fixedly installed on the side wall of the corresponding connecting seat 5. Multiple electric telescopic rods 24 are symmetrically installed on the upper and lower end faces of each fixing plate 23. The other end of the multiple electric telescopic rods 24 located on the same side is jointly installed with a sealing plate 25, and the sealing plate 25 is adapted to the opening size of the inclined air duct 6. It should be noted that the multiple electric telescopic rods 24 located on the same side are all controlled by the same PLC, thereby ensuring that they can extend and retract synchronously. In turn, by moving the sealing plate 25, the hot air in each inclined air duct 6 can be flexibly controlled, and the opening and closing of the hot air in the inclined air duct 6 and the adjustment of the air volume can be realized.

[0018] Furthermore, each hot air conveying assembly includes an air supply seat 4, and each air supply seat 4 is installed on the outside of the drying chamber 1, and each air supply seat 4 is connected to a corresponding connecting seat 5. Each air supply seat 4 is equipped with a fan 22 and multiple heating tubes 21.

[0019] Furthermore, the vibration mechanism includes a drive motor 12, which is mounted on the top surface of the drying chamber 1. The bottom output shaft of the drive motor 12 passes through the drying chamber 1 and is coaxially connected to a rotating shaft 16. Multiple cams 17 are mounted on the outer side of the rotating shaft 16, and the multiple cams 17 abut against the outer side of the corresponding placement frame 11 and collection box 10 respectively. Multiple spring telescopic rods 18 are installed between the outer side of each placement frame 11 and collection box 10 and the side wall of the drying chamber 1. The drive motor 12 provides stable power, and the cam 17 and the spring telescopic rod 18 work together to generate stable vibration, ensuring that the edible fungi can be fully turned and fall, thus improving the vibration effect and equipment stability.

[0020] Furthermore, an inclined plate 13 is installed between the inner walls of both sides of the drying oven 1, and multiple L-shaped guide tubes 14 are installed on the inclined plate 13. Several through holes 15 are opened on the outer side of the drying oven 1, and each through hole 15 corresponds to the bottom end of the inclined plate 13. It can promptly remove the moisture generated during drying, preventing excessive humidity inside the chamber from affecting drying efficiency, while also preventing moisture condensation and backflow from affecting edible fungi, thus ensuring drying quality.

[0021] Furthermore, a sealed rotating door 3 is installed on the outside of the drying oven 1, a controller 2 is installed on the outside of the drying oven 1, and two guide rails 7 are symmetrically installed on the bottom wall of the drying oven 1, and the bottom plate 8 is slidably connected to each guide rail 7.

[0022] In practical use, the working principle of this utility model is as follows: First, the operator opens the sealed rotating door 3, puts the edible fungi to be dried into the placement frame 11 on top, closes the sealed rotating door 3 and starts the equipment. The drive motor 12 drives the rotating shaft 16 to rotate, so that the cam 17 pushes the placement frame 11 and the collection box 10. With the help of the spring telescopic rod 18, reciprocating vibration is generated, so that the edible fungi are evenly distributed on the roller 20. At the same time, the heating tube 21 in the air supply seat 4 is powered on and heats up. The fan 22 sends hot air into the connecting seat 5, and then blows it down to the placement frame 11 through the inclined air duct 6. The weight detection plate 19 monitors the weight of edible fungi in each placement frame 11 in real time, and judges the distribution and quantity based on the initial weight. The controller 2 controls the electric telescopic rod 24 through the PLC, which drives the sealing plate 25 to adjust the opening and closing of the inclined air duct 6 and the air volume. For example, if the weight of edible fungi in the top placement frame 11 is large, it means that there are many edible fungi in this layer. The controller 2 will control the electric telescopic rod 24 of the corresponding inclined air duct 6 to retract, so that the sealing plate 25 opens more wide and increases the hot air volume in this area. When the weight of edible fungi in a certain layer of placement frame 11 in the middle decreases sharply, it means that most of them have fallen to the lower layer. The controller 2 will control the electric telescopic rod 24 of the corresponding inclined air duct 6 to extend, so that the sealing plate 25 reduces the opening or even closes, reducing unnecessary hot air delivery. When the top edible fungi dry to a certain extent, their volume shrinks and they fall into the lower placement frame 11 through the gap of the roller 20 with vibration. The gap of the lower roller 20 is smaller, and drying continues. The moisture generated during drying flows along the inclined plate 13, exits the chamber through the L-shaped conduit 14 and the through hole 15, and finally, the dried edible fungi fall into the collection box 10. The operator can open the sealed rotating door 3 to take out the edible fungi in the collection box 10.

[0023] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
