Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a high-efficiency drying equipment for primary processing of agricultural products. Background Technology

[0002] High-efficiency drying equipment for primary processing of agricultural products is a device that rapidly removes moisture from agricultural products using advanced heat treatment technology. It is primarily used for the initial processing of fruits, vegetables, and grains to extend shelf life and preserve nutrients and flavor. This equipment typically employs technologies such as hot air circulation, microwave heating, or vacuum drying to improve drying efficiency and save energy. Its core advantage lies in its precise control of temperature, humidity, and airflow, ensuring uniform drying of agricultural products and preventing over-drying or loss of nutrients. The hot air circulation system effectively improves thermal efficiency, accelerates the drying process, shortens production time, and reduces energy consumption. This drying equipment is suitable for large-scale agricultural production, effectively preserving the color, taste, and nutrients of agricultural products, and is widely used in vegetable dehydration, fruit preserves production, and grain storage. Its energy-saving and environmentally friendly features make it suitable for the needs of the modern agricultural processing industry.

[0003] Patent CN219454500U discloses a drying device for agricultural product processing. Specifically, the patent discloses a technical solution comprising a main body, a dispersing mechanism, and a noise reduction mechanism. The main body includes a machine platform, a fan frame, and a dryer assembly. The fan frame is fixedly connected to the upper end of the machine platform; the dryer assembly is fixedly connected to the lower end of the fan frame; a dispersing mechanism is installed at the upper end of the main body; the dispersing mechanism includes a support, a motor, a rotating rod, a material cylinder, an air vent, a cylinder cover, an inner insert, a sliding column, a support rod, and a sliding ball; the support is fixedly connected to the upper end of the machine platform; the motor is fixedly connected to the upper end of the support; the rotating rod is inserted inside the motor; and the material cylinder is fixedly connected to one end of the rotating rod. This solution achieves the technical effect of "quickly dispersing and drying agricultural products simultaneously by installing a dispersing mechanism, saving work efficiency; and reducing vibration noise and improving the operational stability of the main body by installing a noise reduction mechanism."

[0004] Due to the poor sealing of the material cylinder in the existing equipment, hot air leakage will cause uneven temperature and air force distribution in different parts of the material cylinder, resulting in inconsistent drying of agricultural products and affecting product quality.

[0042] Example

[0043] like Figure 1-6 As shown, this utility model provides a technical solution: a high-efficiency drying equipment for primary processing of agricultural products, comprising:

[0044] The base 1 has a sealing cover 2 fixedly installed on its top. The base 1 has an internal discharge port. The base 1 supports the entire device, while the sealing cover 2 provides a sealed environment for drying. As the foundational support structure of the entire drying equipment, the base 1 provides stable mounting positions for other components, ensuring stability during operation. The sealing cover 2 isolates the drying area from the external environment, forming a relatively sealed space, reducing heat loss, improving drying efficiency, and preventing external impurities from affecting the quality of dried agricultural products.

[0045] A cleaning component is located inside the sealing cover 2 and is used to clean up debris that falls during the drying process.

[0046] The fixing component is located on one side of the base 1 and is used to fix and seal the drying structure.

[0047] The cleaning components include:

[0048] The first motor 3 is fixedly installed on the top of the base 1. The motor is used to drive the cleaning component. The first motor 3 serves as the power source for the cleaning component. When it is necessary to clean up the debris that falls off during the drying process, the first motor 3 is started. It converts electrical energy into mechanical energy to provide power for subsequent cleaning actions.

[0049] The first threaded rod 4 has one end coaxially fixedly connected to the output end of the first motor 3 via a coupling. After the first motor 3 starts, it drives the first threaded rod 4 to rotate around its own axis via the coupling. The coupling plays the role of transmitting torque and buffering and damping, ensuring that the power of the first motor 3 can be smoothly transmitted to the first threaded rod 4.

[0050] The first threaded block 5 is threadedly connected to the outer periphery of the first threaded rod 4, and the bottom of the first threaded block 5 is in close contact with the top of the base 1. Because the first threaded block 5 is threadedly connected to the first threaded rod 4 and the bottom of the first threaded block 5 is in close contact with the top of the base 1, when the first threaded rod 4 rotates, the first threaded block 5 will move linearly along the axis of the first threaded rod 4, thereby realizing the horizontal movement of the cleaning assembly. The cleaning assembly also includes:

[0051] The cleaning box 6 is fixedly installed on the top of the first threaded block 5. The cleaning box 6 is equipped with a vacuum pump. The cleaning box 6 is used to store the sucked-in agricultural product debris. The cleaning box 6 moves together with the first threaded block 5. When the vacuum pump inside works, it generates negative pressure to suck the surrounding agricultural product debris into the cleaning box 6, thereby achieving the purpose of cleaning the debris. The cleaning box 6 provides storage space for the sucked-in debris.

[0052] Cleaning pipe 7, one end of which is fixedly connected to the top of cleaning box 6, and the other end of cleaning pipe 7 away from cleaning box 6 is close to the top of base 1. Cleaning pipe 7 is used to suck up debris. Cleaning pipe 7 serves as a dust suction channel. One end of cleaning pipe 7 is connected to cleaning box 6, and the other end is close to the top of base 1. Under the action of the dust suction pump, agricultural product debris on the top of base 1 and around it is sucked into cleaning box 6 through cleaning pipe 7, thereby achieving the cleaning and collection of debris.

[0053] The fixed components include:

[0054] The second threaded rod 8 is rotatably connected to the top of the base 1. The second threaded rod 8 can rotate around its own axis on the top of the base 1, providing a basis for the subsequent movement of the second threaded block 9. By rotating the second threaded rod 8, the action of the fixing component can be realized, and the fixing and sealing operation of the drying structure can be completed.

[0055] The second threaded block 9 is threaded to the outer periphery of the second threaded rod 8. The bottom of the second threaded block 9 is in close contact with the top of the base 1. When the second threaded rod 8 rotates, the second threaded block 9 will move in a straight line along the axial direction of the second threaded rod 8 because the second threaded block 9 is threaded to the second threaded rod 8 and its bottom is in close contact with the top of the base 1.

[0056] The connecting rod 10 is fixedly installed on the top of the second threaded block 9. The connecting rod 10 moves together with the second threaded block 9. It serves to connect the second threaded block 9 and the sealing cover 11, and transmits the linear motion of the second threaded block 9 to the sealing cover 11, thereby driving the sealing cover 11 to move.

[0057] The sealing cover 11 is rotatably connected to the end of the connecting rod 10 away from the second threaded block 9 via a bearing. The sealing cover 11 moves under the drive of the connecting rod 10 and is rotatably connected to the connecting rod 10 via a bearing, so that the sealing cover 11 can better cooperate with the drying structure when it rotates with the drying drum 13.

[0058] The sealing strip 25 is fixedly installed on the side of the sealing cover 11 away from the connecting rod 10. The sealing strip 25 is installed on the sealing cover 11. When the sealing cover 11 is in contact with the drying structure, the sealing strip 25 can fill the gap between the sealing cover 11 and the drying structure, enhance the sealing effect, and prevent heat loss and external impurities from entering.

[0059] A feed pipe 12 is rotatably connected to the side of the sealing cover 2 away from the sealing cap 11. One end of the feed pipe 12 is coaxially and fixedly connected to the drying drum 13. A filter screen 14 is provided on the outer periphery of the drying drum 13. Multiple fixing rods 15 are fixedly installed inside the drying drum 13. A fixing frame 16 is fixedly installed on the top of the base 1. A telescopic rod 17 is fixedly installed on the bottom of the fixing frame 16. A dryer 18 is fixedly installed on the bottom of the telescopic rod 17. The telescopic rod 17 passes through the top of the sealing cover 2. The dryer 18 is located inside the sealing cover 2. Agricultural products enter the drying drum 13 through the feed pipe 12. The filter screen 14 on the outer periphery of the drying drum 13 can prevent agricultural products from falling out of the drying drum 13 during the drying process, while allowing hot air to pass through to ensure the drying effect. The fixing rods 15 are located inside the drying drum 13 to prevent agricultural products from piling up and affecting the uniformity of drying. The fixed frame 16 provides installation support for the telescopic rod 17. The telescopic rod 17 can adjust the height of the dryer 18 to maintain a suitable distance from the drying drum 13. When the dryer 18 is working, it generates hot air to dry the agricultural products in the drying drum 13.

[0060] The bottom of the base 1 is rotatably connected to a first support rod 19 and a second support rod 20. The first support rod 19 and the second support rod 20 are rotatably connected, and a slider 21 is rotatably connected to the bottom of the first support rod 19 and the second support rod 20. The first support rod 19 and the second support rod 20 form a movable support structure through this rotatable connection. When the equipment is subjected to external force or changes in its own weight distribution, the first support rod 19 and the second support rod 20 can rotate relative to each other, simultaneously moving the slider 21 at the bottom, thereby adjusting the support state of the equipment and playing a role in buffering and stabilizing the equipment. A support plate 22 is provided at the bottom of the slider 21, and a sliding rod 23 is fixedly installed on the top of the support plate 22. Damping springs 24 are sleeved at both ends of the sliding rod 23. One end of the damping spring 24 is fixedly connected to the slider 21, and the slider 21 is slidably connected to the outer periphery of the sliding rod 23. When the slider 21 moves under the action of the first support rod 19 and the second support rod 20, the slider 21 slides along the sliding rod 23, and the damping spring 24... The slider 21 acts as a buffer and shock absorber during its sliding process, absorbing the vibration energy received by the equipment and reducing the impact of vibration on the equipment. At the same time, the support plate 22 provides a stable bottom support for the entire support structure, ensuring the stability of the equipment during operation. A second motor 26 is fixedly installed at one end of the sealing cover 2 near the feed pipe 12. The output end of the second motor 26 is coaxially fixedly connected to the first gear 27 through a coupling. The outer circumference of the feed pipe 12 is coaxially fixedly connected to the second gear 28. The outer tooth surfaces of the first gear 27 and the second gear 28 mesh. After the second motor 26 starts, it drives the first gear 27 to rotate through the coupling. Since the outer tooth surfaces of the first gear 27 and the second gear 28 mesh, the rotation of the first gear 27 will drive the second gear 28 to rotate, which in turn drives the feed pipe 12, which is coaxially fixedly connected to the second gear 28, to rotate. Finally, the drying drum 13 rotates, realizing the turning of agricultural products during the drying process and improving the drying uniformity.

[0061] The working process of this utility model:

[0062] Step 1: The pre-treated agricultural products are fed into the drying drum 13 through the feed pipe 12. Multiple fixing rods 15 are fixedly installed inside the drying drum 13 to prevent the agricultural products from piling up and ensure even distribution. After feeding, the second threaded rod 8 is rotated, causing the second threaded block 9 to move linearly along the axis of the second threaded rod 8. This moves the sealing cover 11 via the connecting rod 10 until the sealing cover 11 tightly fits the drying structure, and the sealing strip 25 fills the gaps, achieving a seal at the end of the drying drum 13. At this point, the sealing cover 2 encloses the entire drying area, providing a sealed environment for the drying process. The dryer 18 is then started and extended / retracted. The height of the dryer 18 is adjusted by lever 17 to maintain a suitable distance from the drying drum 13. When the dryer 18 is working, it generates hot air, which enters the drying drum 13 through the filter screen 14 to dry the agricultural products. At the same time, the second motor 26 is started. The second motor 26 drives the first gear 27 to rotate through the coupling. Since the outer peripheral teeth of the first gear 27 and the second gear 28 mesh, the rotation of the first gear 27 drives the second gear 28 to rotate, which in turn drives the feed pipe 12, which is coaxially fixedly connected to the second gear 28, to rotate. Finally, the drying drum 13 is rotated, so that the agricultural products are turned over during the drying process, which improves the uniformity of drying.

[0063] Step 2: During the drying process, some agricultural products may fall off. At this time, the first motor 3 is started. The first motor 3 drives the first threaded rod 4 to rotate around its own axis through the coupling. Since the first threaded block 5 is threadedly connected to the first threaded rod 4 and its bottom is close to the top of the base 1, the first threaded block 5 will move in a straight line along the axis of the first threaded rod 4, which will drive the cleaning box 6 to move. When the dust pump inside the cleaning box 6 works, it generates negative pressure, which sucks the agricultural product debris from the top of the base 1 and the surrounding area into the cleaning box 6 through the cleaning pipe 7, thereby cleaning and collecting the debris, keeping the inside of the equipment clean, and preventing the debris from affecting the drying effect and normal operation of the equipment.

[0064] Step 3: Once the agricultural products have reached the required drying level, turn off the dryer 18 and the second motor 26 to stop the drying and turning operations. Then, rotate the second threaded rod 8 in the opposite direction to move the sealing cover 11 away from the drying structure, open the seal, and allow the dried agricultural products to fall out of the drying drum 13 through the discharge port inside the base 1, and then collect them from the discharge port.

[0065] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
