[0002] Fruit processing and drying equipment is a mechanical device used to dehydrate fresh fruit and make it into dried fruit. This type of equipment removes moisture from the fruit by controlling factors such as temperature, humidity and airflow speed, thereby extending the shelf life and facilitating storage and transportation.

[0003] Currently, people use drying boxes to dry fruits. Drying boxes usually dry the fruit by heating the air inside the box and then blowing it out onto the fruit. However, this drying method can result in some fruits near the air outlet being dried while those further away from the air outlet are not completely dried, leading to uneven drying and affecting the quality of the dried fruit. Utility Model Content

[0004] The purpose of this invention is to provide a fruit processing and drying equipment that has the advantage of uniform drying, cleverly solving the problem of uneven drying that may occur in traditional drying equipment, and further improving the drying effect and product quality through a rotation mechanism.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fruit processing and drying device, comprising a drying outer barrel arranged parallel to the ground, with support frames fixedly fitted on both the left and right sides of the drying outer barrel, and a drying inner barrel rotatably connected inside the drying outer barrel.

[0006] The inner drying cylinder and the outer drying cylinder are located on the same axis. The inner drying cylinder has multiple openings equidistantly spaced on its circumferential surface. A rotating shaft is fixedly connected to the center of one side of the inner drying cylinder. An annular cover is fixedly connected to one side of the outer wall of the outer drying cylinder. The end of the rotating shaft away from the inner drying cylinder passes through the outer drying cylinder and extends into the interior of the annular cover. The rotating shaft is rotatably connected to the outer drying cylinder and the annular cover. At least four horizontal pipes are fixedly connected in a circumferential array on the inner wall of the outer drying cylinder. The horizontal pipes are parallel to the inner drying cylinder. Multiple air jets are fixedly connected to one side of the four horizontal pipes near the circumferential surface of the inner drying cylinder.

[0007] As a preferred embodiment of the fruit processing and drying equipment of this utility model, the rotating shaft is fixedly fitted with a driven gear on the inner surface of the annular cover, and a connecting pipe is fixedly connected to one side of each of the four horizontal tubes. The ends of the four connecting pipes away from the horizontal tubes extend to the outside of the drying outer barrel and are fixedly connected thereto.

[0008] As a preferred embodiment of the fruit processing and drying equipment of this utility model, an annular tube is fixedly sleeved on the circumferential surface of the annular cover, and the four connecting tubes are fixedly connected to one side of the annular tube at the ends away from the horizontal tube. The driven gear is meshed with a driving gear at the bottom.

[0009] As a preferred embodiment of the fruit processing and drying equipment of this utility model, a power motor is fixedly connected to the inner wall of the annular cover on the side away from the drying outer barrel, the output shaft of the power motor extends to the inner wall of the drive gear and is fixedly connected thereto, and an air supply pipe is fixedly connected to one side of the top of the annular tube.

[0010] In a preferred embodiment of the fruit processing and drying equipment of this utility model, the air supply pipe is fixedly connected to the air outlet of a hot air blower at the end away from the annular pipe, and the annular cover is fixedly connected to a positioning plate on the side away from the outer wall of the drying outer barrel, with the top of the positioning plate fixedly connected to the bottom of the hot air blower.

[0011] As a preferred embodiment of the fruit processing and drying equipment of this utility model, the inner drying cylinder is movably connected to a No. 1 sealing door on the side away from the rotating shaft, the outer drying cylinder is movably connected to a No. 2 sealing door on the side away from the annular cover, and a controller for controlling the entire equipment is fixedly connected to the center of the front surface of the outer drying cylinder.

[0012] As a preferred embodiment of the fruit processing and drying equipment of this utility model, a handle is fixedly connected to the side of the first sealing door away from the surface of the inner drying cylinder, and a handle is fixedly connected to the side of the second sealing door away from the surface of the outer drying cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a starting motor to drive the active gear to rotate, which in turn drives the driven gear meshing with it to rotate synchronously. As the driven gear rotates, it drives the rotating shaft to rotate. The rotating shaft is connected to the drying inner cylinder, allowing the drying inner cylinder to rotate during the drying process. As the drying inner cylinder rotates, the fruit inside tumbles continuously, ensuring that each fruit receives uniform heating treatment and avoiding problems such as local overheating or insufficient drying.

[0015] 2. According to the parameters set by the controller, the hot air blower starts to work and generates a high-temperature airflow. This hot air is first sent into the annular pipe through the air supply pipe. The annular pipe is responsible for receiving the hot air from the hot air blower and distributing it evenly to the four connecting pipes. Each connecting pipe then guides the hot air into the corresponding horizontal pipe. Multiple jet nozzles are installed on the horizontal pipes, which face the openings of the drying inner cylinder. As the hot air is ejected through the jet nozzles, it acts directly on the rotating drying inner cylinder, penetrates the openings, and allows the hot air to contact the fruit inside, accelerating the evaporation of moisture.

[0021] Please see Figures 1-4 A fruit processing and drying device includes a drying outer barrel 1 arranged parallel to the ground, with support frames 2 fixedly fitted on both the left and right sides of the drying outer barrel 1, and a drying inner barrel 3 rotatably connected inside the drying outer barrel 1.

[0022] The outer drying drum 1 is used to house the entire drying assembly. The support frame 2 is fixed on both sides of the outer drying drum 1 to provide stability and support. The inner drying drum 3 is located inside the outer drying drum 1 and is rotated by a rotating connection. It is coaxial with the outer drying drum 1. Multiple openings 4 are equidistantly opened on the surface of the inner drying drum 3 to facilitate air circulation for drying the fruit.

[0023] Furthermore, the inner drying cylinder 3 and the outer drying cylinder 1 are located on the same axis. Multiple openings 4 are equidistantly opened on the circumferential surface of the inner drying cylinder 3. A rotating shaft 5 is fixedly connected to the center of one side of the inner drying cylinder 3. An annular cover 6 is fixedly connected to one side of the outer wall of the outer drying cylinder 1. The end of the rotating shaft 5 away from the inner drying cylinder 3 passes through the outer drying cylinder 1 and extends into the interior of the annular cover 6. The rotating shaft 5 is rotatably connected to the outer drying cylinder 1 and the annular cover 6. At least four horizontal pipes 10 are fixedly connected in a circumferential array on the inner wall of the outer drying cylinder 1. The horizontal pipes 10 are arranged parallel to the inner drying cylinder 3. Multiple air jets 11 are fixedly connected at equal intervals on the side of the four horizontal pipes 10 near the circumferential surface of the inner drying cylinder 3.

[0024] One end of the rotating shaft 5 is fixed at the center of one side of the inner drying cylinder 3, and the other end extends through the outer drying cylinder 1 into the interior of the annular cover 6, so that the inner drying cylinder 3 can rotate freely inside the outer drying cylinder 1. The annular cover 6 is fixed to the outside of the outer drying cylinder 1, providing additional support and protection for the rotating shaft 5 and allowing it to rotate freely. At least four horizontal pipes 10 are provided, evenly distributed on the inner wall of the outer drying cylinder 1, parallel to the inner drying cylinder 3. Each horizontal pipe 10 has multiple air jets 11 installed on the side facing the inner drying cylinder 3.

[0025] During drying, heated air is injected into the outer drying drum 1 through the jet nozzle 11 on the horizontal tube 10, directly acting on the rotating inner drying drum 3. Since the inner drying drum 3 has multiple openings 4, hot air can penetrate the inner drying drum 3 and directly contact the fruit placed inside, accelerating moisture evaporation. The rotation of the inner drying drum 3 helps ensure that all fruits are evenly exposed to the hot air, reducing uneven drying caused by different positions. This design not only improves drying efficiency but also better preserves the color, flavor, and nutrients of the fruit.

[0026] Furthermore, the driven gear 7 is fixedly sleeved on the inner surface of the rotating shaft 5 inside the annular cover 6, and a connecting pipe 12 is fixedly connected to one side of each of the four horizontal tubes 10. The end of each of the four connecting pipes 12 away from the horizontal tubes 10 extends to the outside of the drying outer barrel 1 and is fixedly connected to it.

[0027] Driven gear 7 is used to transmit power, driving shaft 5 and drying inner cylinder 3 connected to it to rotate. One end of each horizontal tube 10 is connected to the external hot air delivery system through connecting pipe 12 to ensure that hot air can be delivered stably and efficiently to each horizontal tube 10.

[0028] Furthermore, an annular tube 13 is fixedly sleeved on the circumferential surface of the annular cover 6, and the ends of the four connecting tubes 12 away from the horizontal tube 10 are fixedly connected to one side of the annular tube 13. The driven gear 7 is meshed with the driving gear 8 at the bottom.

[0029] The function of the annular pipe 13 is to act as a central distributor, distributing hot air evenly to each connecting pipe 12, and then delivering it to the horizontal pipe 10.

[0030] Furthermore, a power motor 9 is fixedly connected to the inner wall of the annular cover 6 on the side away from the drying outer barrel 1. The output shaft of the power motor 9 extends to the inner wall of the drive gear 8 and is fixedly connected thereto. An air supply pipe 14 is fixedly connected to one side of the top of the annular tube 13.

[0031] When the power motor 9 starts, the output shaft drives the drive gear 8 to rotate. Through meshing with the driven gear 7, the power is transmitted to the rotating shaft 5, thereby driving the inner drying cylinder 3 to rotate stably inside the outer drying cylinder 1. By adjusting the speed of the power motor 9, the rotation speed of the inner drying cylinder 3 can be precisely controlled to adapt to the drying needs of different kinds of fruits. The uniform rotation of the inner drying cylinder 3 can make the fruits tumble continuously and be heated evenly, avoiding local overheating or undried phenomena, and significantly improving product quality.

[0032] Furthermore, the air supply pipe 14 is fixedly connected to the air outlet of the hot air blower 15 at the end away from the annular pipe 13, and the annular cover 6 is fixedly connected to the positioning plate 16 on the side away from the outer wall of the drying outer barrel 1, with the top of the positioning plate 16 fixedly connected to the bottom of the hot air blower 15.

[0033] After the hot air blower 15 is started, the generated hot air enters the annular pipe 13 through the air supply pipe 14. Since the annular pipe 13 surrounds the annular cover 6, it can evenly distribute the hot air in four directions. The hot air coming out of the annular pipe 13 flows into the four horizontal pipes 10 through the four connecting pipes 12. Each horizontal pipe 10 is equipped with multiple jet nozzles 11 arranged at equal intervals. The jet nozzles 11 directly face the rotating drying inner cylinder 3, so that the hot air can effectively penetrate the openings 4 on the surface of the inner cylinder to achieve the best heat exchange effect. The positioning plate 16 not only provides the necessary support for the hot air blower 15, but also enhances the structural stability of the entire device, helps to reduce vibration and noise during operation, and ensures long-term stable operation of the equipment.

[0034] Furthermore, a first sealing door 17 is movably connected to the side of the inner drying drum 3 away from the rotating shaft 5, and a second sealing door 19 is movably connected to the side of the outer drying drum 1 away from the annular cover 6. A controller 21 for controlling the entire equipment is fixedly connected to the center of the front surface of the outer drying drum 1.

[0035] The No. 1 sealing door 17 is used to open or close the feed inlet of the inner drying cylinder 3, making it convenient to put in or take out fruit materials, and maintaining good sealing during the drying process to prevent heat loss. The No. 2 sealing door 19 is used to open or close the outer drying cylinder 1, and can also be used for inspection, maintenance and cleaning of the internal structure. The controller 21 is the operation control center of the whole equipment. Through the controller 21, parameters such as temperature, air volume, inner cylinder rotation speed, and drying time can be adjusted to realize intelligent control and real-time monitoring of the entire drying process.

[0036] Furthermore, a handle 18 is fixedly connected to the side of the first sealing door 17 away from the surface of the inner drying drum 3, and a handle 20 is fixedly connected to the side of the second sealing door 19 away from the surface of the outer drying drum 1.

[0037] Handle 18 is used to manually open or close the No. 1 sealing door 17, making it easy for operators to quickly and effortlessly open the feed inlet for loading or unloading fruit. Handle 20 is used to maintain the internal structure of the drying outer barrel 1. This handle enhances the user-friendliness of the equipment and makes maintenance more convenient and efficient.

[0038] First, the operator opens the second sealing door 19 using the second handle 20, and then opens the first sealing door 17 using the first handle 18. The fresh fruit to be dried is then loaded into the drying inner drum 3. After completion, the first sealing door 17 and the second sealing door 19 are closed and sealed tightly to prevent heat loss during the drying process.

[0039] The drive motor 9 is started to drive the drive gear 8 to rotate. The drive gear 8 drives the driven gear 7, which meshes with it, to rotate synchronously. As the driven gear 7 rotates, it drives the rotating shaft 5 to rotate. The rotating shaft 5 is connected to the drying inner cylinder 3, so that the drying inner cylinder 3 can rotate during the drying process. As the drying inner cylinder 3 rotates, the fruits inside tumble continuously, ensuring that each fruit can be heated evenly and avoiding problems such as local overheating or insufficient drying.

[0040] According to the parameters set by the controller 21, the hot air blower 15 starts to work and generates a high-temperature airflow. This hot air is first sent into the annular pipe 13 through the air supply pipe 14. The annular pipe 13 is responsible for receiving the hot air from the hot air blower 15 and distributing it evenly to the four connecting pipes 12. Each connecting pipe 12 then guides the hot air into the corresponding horizontal pipe 10. Multiple jet nozzles 11 are installed on the horizontal pipe 10, which face the openings 4 of the drying inner cylinder 3. As the hot air is sprayed out through the jet nozzles 11, it acts directly on the rotating drying inner cylinder 3, penetrates the openings 4, and allows the hot air to contact the fruit inside, accelerating the evaporation of moisture.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
