Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to a microwave drying device for vegetable products. Background Technology

[0002] Microwave drying equipment for vegetable products is a modern device that uses microwave energy for rapid, uniform, and efficient drying. The microwave dryer generates high-frequency electromagnetic waves through a microwave generator. These microwaves are transmitted into the drying chamber and penetrate the material, causing the internal temperature of the material to rise. As the temperature rises, the moisture in the material begins to vaporize, forming water vapor that escapes from the surface of the material. At the same time, the microwave dryer is usually equipped with a dehumidification system to remove the generated water vapor in a timely manner.

[0003] The existing technology has the following problems:

[0004] The existing equipment cannot perform up-and-down reciprocating vibration during use. The lack of up-and-down reciprocating vibration may lead to uneven heating of vegetable products during the drying process, with some areas being over-dried while others are under-dried. This uneven drying will affect the overall quality and taste of the product. Vibration helps improve the flowability and mixability of materials, thereby promoting the uniform distribution of heat and moisture. Without vibration, the drying process may take longer to achieve the desired drying effect, reducing production efficiency. Furthermore, the existing equipment cannot disassemble and replace the dehumidification plates during use. As the performance of the dehumidification plates deteriorates, higher microwave power and longer operating time may be required to achieve the same drying effect, thus increasing energy consumption. If the dehumidification plates are not replaced or cleaned regularly, their dehumidification effect will gradually decrease, leading to a reduction in drying efficiency. Utility Model Content

[0024] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0025] like Figure 1-2 As shown, this utility model provides a microwave drying device for vegetable products, including a body 1. A door 2 is rotatably connected to the front of the body 1. A dehumidifying chamber 3 is fixedly connected to the right side of the body 1. A fan 4 is also fixedly connected to the right side of the body 1. The input pipe of the fan 4 is fixedly connected through the dehumidifying chamber 3, and the output pipe of the fan 4 is fixedly connected through the body 1. A microwave generator 5 is fixedly connected to the upper inner wall of the body 1. The microwave generator 5 is existing technology and will not be described in detail here. A sliding groove 6 is formed on the inner wall of the body 1. Multiple limiting rods 7 are fixedly connected to the upper inner wall of the sliding groove 6. The outer wall of the machine is slidably connected to a ventilation plate 8, and the outer wall of the ventilation plate 8 is slidably connected to the slide groove 6. A vibration mechanism 9 is provided on the lower inner wall of the machine body 1. During the use of the device, the machine door 2 can be opened first, and vegetable products can be placed on the upper side of the ventilation plate 8. Then the machine door 2 can be closed. After that, the microwave generator 5 and the vibration mechanism 9 can be turned on. The microwave generator 5 raises the temperature of the vegetable products and evaporates the internal moisture. The vibration mechanism 9 can make the vegetable products vibrate up and down. Then the fan 4 can be turned on. The fan 4 can draw the humid air inside the machine body 1 into the dehumidification box 3 for dehumidification.

[0026] like Figure 3As shown, this utility model provides a technical solution: Preferably, the vibration mechanism 9 includes a support plate 91, a motor 92 fixedly connected to the rear side of the support plate 91, a first gear 93 fixedly connected to the output shaft of the motor 92, two second gears 94 meshing with the outer wall of the first gear 93, a rotating shaft 95 fixedly connected through the front side of the second gears 94, the rear end of the rotating shaft 95 rotatably connected to the support plate 91, a half gear 98 fixedly connected to the front end of the rotating shaft 95, a support plate 99 fixedly connected to the front side of the support plate 91, a lifting column 96 slidably connected through the upper side of the support plate 99, racks 97 fixedly connected to both sides of the lifting column 96, the outer wall of the half gear 98 meshing with the rack 97, and the upper side of the lifting column 96 fixedly connected to the ventilation plate 8. When vibrating vegetable products, it can... The motor 92 is started, which drives the first gear 93 to rotate. When the first gear 93 rotates, it simultaneously drives the two second gears 94 to rotate. The rotation of the second gears 94 drives the half gear 98 to rotate through the rotating shaft 95. The rotation of the left half gear 98 drives the lifting column 96 to descend through the rack 97. Since the half gear 98 only has half a turn of teeth, when the half gear 98 rotates half a turn and disengages from the rack 97, the right half gear 98 just meshes with the right rack 97, thereby realizing the up and down movement of the lifting column 96. The movement of the lifting column 96 drives the ventilation plate 8 to move up and down, thus vibrating the vegetable products on the upper side of the ventilation plate 8, avoiding local overheating or uneven drying, thereby improving the uniformity of drying and the overall quality of the product.

[0027] like Figure 4-6As shown, this utility model provides a technical solution: Preferably, a dehumidifying plate 11 is movably connected to the inner wall of the dehumidifying box 3. A locking mechanism 10 is provided on both the front and rear sides of the dehumidifying box 3. The locking mechanism 10 includes a knob 101. A threaded rod 102 is fixedly connected to the side of the knob 101 near the dehumidifying plate 11. A movable block 103 is threadedly connected to the outer wall of the threaded rod 102. Two inclined grooves 104 are provided on the upper side of the movable block 103. A limiting post 105 is slidably connected to the inner surface of the inclined groove 104. A moving block 106 is fixedly connected to the upper end of the limiting post 105. A fixing plate 107 is fixedly connected inside the dehumidifying box 3. The outer wall of the fixing plate 107 is slidably connected to the moving block 106. A connecting plate 108 is rotatably connected to the upper side of the moving block 106. An insert block 109 is rotatably connected to the other end of the connecting plate 108. A T-shaped plate 111 is fixedly connected to the upper side of the fixing plate 107. Two connecting plates are fixedly connected to the upper side of the T-shaped plate 111. The outer wall of the connecting rod 110 is slidably connected to the insert block 109, and the outer wall of the insert block 109 is movably connected to the dehumidification plate 11. When the dehumidification plate 11 needs to be replaced after a long period of dehumidification, the knobs 101 on both sides can be turned first. The knobs 101 drive the threaded rod 102 to rotate. The rotation of the threaded rod 102 can drive the movable block 103 to move. The movement of the movable block 103 can drive the two inclined grooves 104 to move. The cooperation between the inclined grooves 104 and the limiting post 105 can drive the two moving blocks 106 to move simultaneously to the middle or in opposite directions. When the two moving blocks 106 move in opposite directions, they will drive the connecting plate 108 to rotate, thereby driving the insert block 109 to descend on the connecting rod 110. When the insert block 109 is separated from the dehumidification plate 11, the dehumidification plate 11 can be removed, which can ensure that the dehumidification plate 11 always maintains a good working condition, thereby improving the overall drying efficiency.

[0028] The working principle of this microwave drying device for vegetable products will be explained in detail below.

[0029] like Figure 1-6As shown, during the use of the device, the machine door 2 can be opened first, and vegetable products can be placed on the upper side of the ventilation plate 8. Then, the machine door 2 can be closed, and then the microwave generator 5 and vibration mechanism 9 can be turned on. The microwave generator 5 raises the temperature of the vegetable products, evaporating the internal moisture. The vibration mechanism 9 can make the vegetable products vibrate up and down. When vibrating the vegetable products, the motor 92 can be started. The motor 92 can drive the first gear 93 to rotate. When the first gear 93 rotates, it will simultaneously drive the two second gears 94 to rotate. The rotation of the second gears 94 will drive the half gear 98 to rotate through the rotating shaft 95. The rotation of the left half gear 98 can drive the lifting column 96 to descend through the rack 97. Since the half gear 98 only has half a turn of teeth, when the half gear 98 rotates half a turn and disengages from the rack 97, the right half gear 98 just meshes with the right rack 97, thereby realizing the up and down movement of the lifting column 96. The movement of the lifting column 96 will drive the ventilation plate 8 to move up and down, thus allowing the vegetable products on the upper side of the ventilation plate 8 to be vibrated. Vibration prevents localized overheating or uneven drying, thus improving drying uniformity and overall product quality. Then, the fan 4 can be turned on, drawing humid air from inside the unit 1 into the dehumidification chamber 3 for dehumidification. When replacing the dehumidification plate 11 after prolonged dehumidification, the knobs 101 on both sides can be rotated. The knobs 101 rotate the threaded rod 102, which in turn moves the movable block 103. The movable block 103 then moves the two inclined grooves 104. The interaction between the inclined grooves 104 and the limiting post 105 causes the two moving blocks 106 to move simultaneously towards the center or in opposite directions. When the two moving blocks 106 move in opposite directions, they rotate the connecting plate 108, causing the insert block 109 to descend on the connecting rod 110. Once the insert block 109 detaches from the dehumidification plate 11, the dehumidification plate 11 can be removed, ensuring that the dehumidification plate 11 always maintains good working condition and thus improving overall drying efficiency.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
