Description

Technical Field

[0001] This utility model belongs to the field of vegetable drying technology, and in particular relates to an energy-saving and environmentally friendly hot air vegetable drying device. Background Technology

[0002] Dehydrated vegetables, also known as rehydrated vegetables, are made by processing fresh vegetables through chopping, washing, and drying to remove most of the water content. In the current vegetable drying process, drying boxes are usually set up during the conveying of vegetables by conveying equipment to carry out hot air drying, thereby achieving continuous drying of vegetables.

[0003] Patent application CN202420165893.4 discloses an energy-saving and environmentally friendly hot air vegetable drying device, including a conveying device for conveying vegetables. The conveying device is equipped with a drying chamber. It also includes: a turner, located inside the drying chamber, for turning the vegetables on the conveying device; a drive assembly, comprising several drive boxes, a blower, and piping components, wherein the drive boxes are mounted on the drying chamber, and the piping components connect the drive boxes to the drying chamber and to the air inlet of the blower; an impeller is located in the drive box; and a transmission structure connecting the impeller to the turner, enabling the turner to turn the vegetables when the impeller rotates. This energy-saving and environmentally friendly hot air vegetable drying device uses wind power to drive the turner to turn the vegetables on the conveying device, allowing both sides of the vegetables to be quickly heated, thereby shortening the layout length of the conveying device, reducing the number of hot air devices, and lowering energy consumption.

[0004] In the existing technology, multiple impellers driven by a blower are used to drive multiple return feeders to return vegetables, so that both sides of the vegetables can be dried, thereby improving the drying effect. However, there are still shortcomings: First, the existing vegetable drying device has a poor turning effect when turning the vegetables, which makes the vegetables dry slowly and is not conducive to the rapid production of dehydrated vegetables.

[0005] Furthermore, directly introducing ambient air from the outside to drive the turning device will affect the temperature inside the drying chamber, thereby further reducing the drying efficiency of dehydrated vegetables and affecting the rapid production of dehydrated vegetables. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, this invention provides an energy-saving and environmentally friendly hot air vegetable drying device. Through the arrangement of scrapers, a second conveyor belt, and blades, this invention not only transports vegetable particles from the conveying end face of the first conveyor belt to the end face of the horizontal plate via the scrapers and the second conveyor belt, and then drops them back onto the conveying end face of the first conveyor belt, thus turning the vegetable particles, but also allows the rotating shaft and blades to draw hot air blown by the hot air blower into the cavity formed by the scrapers, horizontal plate, second conveyor belt, and the conveying end face of the first conveyor belt through through holes. This allows for secondary air drying during the process of the vegetable particles falling from the end face of the horizontal plate to the conveying end face of the first conveyor belt.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving and environmentally friendly hot air vegetable drying device, comprising a drying chamber, wherein a first conveyor belt is provided inside the drying chamber, and multiple scrapers are arranged obliquely and sequentially above the first conveyor belt between the two side walls of the drying chamber, each scraper having a horizontal plate at one end, a second conveyor belt being rotatably arranged between each scraper and the horizontal plate, and a rotating shaft being rotatably arranged below each horizontal plate, the outer circumference of the rotating shaft having multiple blades, and a hot air fan being provided at the feed inlet of the drying chamber.

[0008] Optionally, each of the second conveyor belts has multiple through holes on its conveying end face, and the diameter of the multiple through holes on each of the second conveyor belts decreases sequentially along the conveying direction of the first conveyor belt.

[0009] Optionally, multiple rollers are rotatably provided on the end face of each of the cross plates.

[0010] Optionally, multiple anti-slip particles are provided on the conveying end face of the first conveyor belt.

[0011] Optionally, each of the scrapers is rotatably provided with a support shaft inside the first conveyor belt below it.

[0012] Optionally, one end of the first conveyor belt is provided with a first support platform inside the drying chamber, and the other end of the first conveyor belt is provided with a second support platform inside the drying chamber.

[0013] Optionally, a baffle plate is provided above the second support platform inside the drying chamber.

[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0015] (1) By setting up the scraper, the second conveyor belt and blades, this utility model not only allows the vegetable particles on the conveying end face of the first conveyor belt to be transported to the end face of the horizontal plate by the scraper and the second conveyor belt, and then fall to the conveying end face of the first conveyor belt, forming a turning of the vegetable particles, so that the turning of the vegetable particles is sufficiently uniform, but also the rotating shaft and blades can draw the hot air blown out by the hot air blower into the cavity formed by the scraper, the horizontal plate, the second conveyor belt and the conveying end face of the first conveyor belt through the through hole, and perform secondary blowing and drying during the process of the vegetable particles falling from the end face of the horizontal plate to the conveying end face of the first conveyor belt, so that the drying of the entire vegetable particles is more comprehensive and effectively improves the drying effect of the device.

[0016] (2) The diameter of the through hole on the end face of the second conveyor belt of this utility model gradually decreases along the conveying direction of the first conveyor belt, so that the vegetable particles lose moisture and gradually become smaller during the conveying process of the first conveyor belt. The above setting can effectively prevent the vegetable particles from falling between the second conveyor belt and the first conveyor belt and causing jamming, and effectively increase the smoothness of the drying process of the device.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1:

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, an energy-saving and environmentally friendly hot air vegetable drying device includes a drying chamber 10. A first conveyor belt 11 is installed inside the drying chamber 10. A first motor 22 is installed on the side wall of the drying chamber 10, providing power for the rotation of the first conveyor belt 11. Multiple scrapers 14 are arranged obliquely between the two side walls of the drying chamber 10 above the first conveyor belt 11. A horizontal plate 15 is installed at one end of each scraper 14. A second conveyor belt 16 is rotatably installed between each scraper 14 and the horizontal plate 15. Multiple through holes 17 are provided on the conveying end face of each second conveyor belt 16. The diameter of the multiple through holes 17 on each second conveyor belt 16 decreases sequentially along the conveying direction of the first conveyor belt 11. A rotating shaft 19 is rotatably installed below each horizontal plate 15. Multiple blades 25 are installed on the outer circular surface of the rotating shaft 19. Multiple first motors 22 are installed on the outer wall of the drying chamber 10, providing power for the rotation of the rotating shaft 19. A hot air blower 13 is installed at the feed inlet of the drying chamber 10.

[0025] Specifically, both the first motor 22 and the second motor 23 are ordinary motors. The output end of the first motor 22 drives the first conveyor belt 11 to rotate, transporting the vegetable granules. The output end of the second motor 23 drives the rotating shaft 19 to rotate, so that the hot air blown by the hot air blower 13 can be used to perform secondary drying during the process of the vegetable granules falling from the end face of the horizontal plate 15 to the conveying end face of the first conveyor belt 11. This allows the hot air blown by the hot air blower 13 to further dry the vegetable granules, effectively improving the drying efficiency of the vegetable granules, thereby reducing energy consumption and achieving environmental protection.

[0026] The second conveyor belt 16 helps the vegetable particles that have moved from the conveying end face of the first conveyor belt 11 to the end face of the scraper 14 to move further to the end face of the horizontal plate 15, so that the vegetable particles can fall from the end face of the horizontal plate 15 to the conveying end face of the first conveyor belt 11, forming a "wheat winnowing" effect, which not only allows the vegetable particles to be turned more thoroughly, but also increases the drying efficiency.

[0027] The diameter of the through holes 17 on the multiple second conveyor belts 16 decreases as they approach the conveying direction of the first conveyor belt 11. This effectively prevents the vegetable particles from gradually decreasing in size during the drying process and leaking through the through holes 17 into the space between the second conveyor belt 16 and the first conveyor belt 11, causing them to accumulate.

[0028] Furthermore, such as Figure 4 As shown, each horizontal plate 15 has multiple rollers 18 rotatably mounted on its end face.

[0029] Specifically, after the vegetable granules are conveyed to the end face of the horizontal plate 15 by the second conveyor belt 16, the roller 18 can reduce the friction between the vegetable granules and the end face of the horizontal plate 15, thereby avoiding the accumulation of vegetable granules on the end face of the horizontal plate 15 and effectively increasing the drying efficiency of the device.

[0030] Furthermore, such as Figure 3 As shown, a first support platform 12 is provided at one end of the first conveyor belt 11 inside the drying chamber 10, and a second support platform 26 is provided at the other end of the first conveyor belt 11 inside the drying chamber 10. A baffle plate 21 is provided above the second support platform 26 inside the drying chamber 10.

[0031] Specifically, both the first support platform 12 and the second support platform 26 serve as a connecting structure between other transmission devices and this drying device. The first support platform 12 reduces the size of the input and output ports of the drying chamber 10. The second support platform 26 also serves as a heat loss prevention structure for the drying chamber 10, effectively preventing heat loss from the interior of the drying chamber 10 and thus ensuring the drying efficiency of the vegetable particles.

[0032] Furthermore, such as Figure 3 As shown, each scraper 14 has a supporting shaft 27 rotatably mounted below it inside the first conveyor belt 11.

[0033] Specifically, the support shaft 27 is located below the scraper 14, which can effectively support the conveying end face of the first conveyor belt 11 and prevent vegetable particles on the conveying end face of the first conveyor belt 11 from being squeezed into the space between the scraper 14 and the first conveyor belt 11 under the action of the belt's toughness, and then being broken by the rotation of multiple blades 25, causing damage to the vegetable particles.

[0034] Example 2:

[0035] Based on Example 1, further examples are made, such as... Figure 4 As shown, multiple anti-slip particles 20 are provided on the conveyor end face of the first conveyor belt 11.

[0036] Specifically, the anti-slip particles 20 increase the friction on the conveying end face of the first conveyor belt 11, allowing the vegetable particles on the conveying end face to move smoothly onto the scraper 14, effectively increasing the working efficiency of the device.
