Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of fruit and vegetable drying equipment, and specifically relates to a fruit and vegetable processing and drying equipment. Background Technology
[0002] Drying during fruit and vegetable processing primarily involves dehydration to extend shelf life, preserve nutrients, and meet processing and storage requirements. Existing technologies typically employ fruit and vegetable dryers. For example, utility model patent CN222322769U discloses a fruit and vegetable dryer comprising a hot air device, a drying device, a drive device, a control cabinet, and a noise reduction device. Fruits and vegetables are loaded into a drying drum, and an air-source heat pump provides hot air into a hot air chamber. The drying drum is positioned above the hot air chamber, and the rotating drum dries the fruits and vegetables. This high-intensity, low-temperature drying method preserves more of the fruits and vegetables' nutrients, resulting in high drying efficiency and environmentally friendly, low-noise operation.
[0003] However, in the aforementioned dryer, the fan outlet is aligned with the hot air box at the bottom of the drum. Hot air must pass through the hot air box before it can move upwards into the drying drum, preventing direct heat contact with the fruits and vegetables and resulting in heat loss. Furthermore, the complex structure of these fruits and vegetables necessitates insulated outer and inner walls and insulation materials to reduce heat loss during heat transfer. Therefore, a drum-type fruit and vegetable processing and drying equipment that allows direct contact between hot air and the fruits and vegetables is needed. Utility Model Content
[0004] This utility model provides a fruit and vegetable processing and drying equipment to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fruit and vegetable processing and drying device includes a support assembly and a drying assembly; the drying assembly is disposed on the support assembly; the drying assembly includes a cylindrical mesh, an external gear, a cover, and a hot air blower; both ends of the cylindrical mesh are movably connected to the cover; the cylindrical mesh is rotatably disposed on the support assembly; the external gear is disposed on the outer wall of the cylindrical mesh; the cover is fixedly disposed on the support assembly; openings are provided at both ends of the cover; the cylindrical mesh is inclined; and the hot air blower is disposed on the cover.
[0006] As a further improvement to the technical solution, the higher-positioned cover is a feeding cover, and the lower-positioned cover is a discharging cover; the feeding cover has a feeding port at the end away from the support component; and the discharging cover has a discharging port at the end closer to the support component.
[0007] As a further improvement to the technical solution, the hot air blower is provided at the end of the feed hood near the support assembly; the hot air blower is provided at the end of the discharge hood away from the support assembly.
[0008] As a further improvement to the technical solution, the support assembly includes a base, a transmission gear, and a motor; the cover is disposed at both ends of the base; the motor is disposed on the base corresponding to the external gear; the output end of the motor is mechanically connected to the transmission gear; the transmission gear meshes with the external gear for transmission; and the cylindrical mesh is rotatably disposed on the base.
[0009] As a further improvement to the technical solution, the drying assembly further includes a roller ring; the roller ring is disposed on the outer wall of the cylindrical mesh; the support assembly further includes a bracket and rollers; the bracket is disposed on the base; the rollers are rotatably disposed on the bracket corresponding to the roller ring; the cylindrical mesh is rotatably disposed on the base through the roller ring and the rollers; the roller ring and the rollers are movably connected.
[0010] As a further improvement to the technical solution, the rolling rings are distributed at both ends of the cylindrical mesh.
[0011] As a further improvement to the technical solution, the support assembly also includes a speed reducer; the speed reducer is mounted on the base; the motor is connected to the transmission gear through the speed reducer; the output end of the motor is connected to one end of the speed reducer; and the end of the speed reducer away from the motor is connected to the transmission gear.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, fruits and vegetables are placed into the cylindrical mesh through the feeding hood. Then, the motor and hot air blower are started. The motor drives the transmission gears via a reducer, which in turn drives the external gears, causing the cylindrical mesh to rotate. The rotating mesh tumbles the fruits and vegetables, changing their position so that the hot air blown by the hot air blower can better contact them. The hot air directly contacts the fruits and vegetables, drying their moisture. As the cylindrical mesh rotates, the rolling rings and rollers rotate, ensuring smooth rotation. This application, by directly mounting the hot air blower on the hood, allows the hot air to directly contact the fruits and vegetables, preventing heat loss during transmission and reducing the overall manufacturing cost of the equipment.
