Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable processing technology, and in particular to a fruit and vegetable dryer that is easy to disassemble and assemble. Background Technology

[0002] In the fruit and vegetable processing industry, drying is a crucial step in extending the shelf life of fruits and vegetables and increasing their added value. Traditional fruit and vegetable drying methods are diverse, such as natural air drying and hot air furnace drying. While natural air drying is less expensive, it is heavily dependent on weather conditions, takes a long time, and is easily contaminated by dust, insects, and other pollutants, leading to a decline in quality. Hot air furnace drying, on the other hand, solves some of the problems associated with natural air drying, providing a relatively stable heat source and drying environment, thus improving drying efficiency.

[0003] However, existing hot air drying equipment still has many shortcomings in practical applications. On the one hand, the overall structure of the equipment is complex, and the connections between various components are mostly fixed. For example, the connection between the heat source and the drying chamber is extremely cumbersome if a component malfunctions or needs to be upgraded or replaced. This not only requires professional technicians but also consumes a lot of time and labor costs, seriously affecting production progress. On the other hand, the delivery and dispersion of hot air during the drying process are not ideal. Hot air often enters the drying chamber from a certain area, resulting in uneven temperature distribution within the drying chamber. Some areas of fruits and vegetables are over-dried, while others are under-dried, seriously affecting the drying quality and consistency of the fruits and vegetables.

[0004] Therefore, this technical solution proposes a fruit and vegetable dryer that is easy to disassemble and assemble, in order to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of complex structure, difficult disassembly and assembly, and uneven heat distribution of existing hot air furnace drying equipment, and to propose a vegetable and fruit dryer that is easy to disassemble and assemble.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A conveniently disassembled and assembled fruit and vegetable dryer includes:

[0008] The hot air drying oven has a door panel hinged to one side of its opening, and an exhaust throttle valve is fixed through the inner wall of the top.

[0009] An air source heat pump is detachably installed on one side of a hot air drying box via a positioning mechanism. Its air outlet is fixed with a flexible connecting pipe that extends into the hot air drying box.

[0010] The supporting mechanism, located inside the hot air drying oven, is used to support fruits and vegetables;

[0011] The dispersing mechanism, installed inside the hot air drying chamber and connected to the flexible connecting pipe, is used to disperse and transport the hot air output from the air source heat pump into the hot air drying chamber to dry the fruits and vegetables on the supporting mechanism.

[0012] In one possible design, the positioning mechanism includes:

[0013] U-shaped positioning support frame, fixed to one side of hot air drying oven;

[0014] U-shaped retaining strips are fixed to the air source heat pump, and are snapped into the U-shaped positioning support frame and fit against the inner wall;

[0015] Two fastening components are respectively connected to the top of both sides of the U-shaped locking strip, extending to the outside of the U-shaped positioning support and connecting to its top, to fix the relative position of the U-shaped locking strip and the U-shaped positioning support.

[0016] In one possible design, the fastening assembly includes:

[0017] The support and fixing ring is rotatably connected to the top of one side of the U-shaped locking strip and is located on the outside of the U-shaped positioning support frame;

[0018] Fastening bolt I is fixed to the support fixing ring and passes through the top of one side of the connecting support frame of the U-shaped positioning support frame;

[0019] Fastening nut I and fastening nut II are threaded onto fastening bolt I, respectively, and are tightly fitted to the top and bottom of the connecting support frame, achieving fastening through bidirectional clamping.

[0020] In one possible design, the supporting mechanism includes multiple mesh frames arranged longitudinally at equal intervals in a hot air drying box. The mesh frames are fixedly installed inside the hot air drying box to support fruits and vegetables.

[0021] In one possible design, multiple steel pipes are fixedly installed at equal intervals on the space frame to improve the stability and load-bearing capacity of the space frame during support.

[0022] In one possible design, the distributed mechanism includes:

[0023] The diversion conduit is fixed inside the hot air drying oven, and a material conveying pipe is fixed through one side of its inner wall. The material conveying pipe is sealed and inserted into the flexible butt joint pipe.

[0024] Multiple injection pipes are fixed at equal intervals through the bottom inner wall of the diversion conduit, with one end extending to the bottom of the material conveying mesh belt. Multiple injection holes corresponding to the material conveying mesh belt and used to spray hot gas are opened on the top inner wall.

[0025] The mounting plate is fixedly connected to one end of multiple spray pipes and is bolted to the inner wall of the hot air drying chamber.

[0026] In this application, during use, the air source heat pump is first secured in the U-shaped positioning support frame on one side of the hot air drying box using a U-shaped clamping strip. Then, the fastening bolt I on the support fixing ring in the fastening assembly is rotated to a vertical position, allowing it to pass through the connecting support frame. Next, the fastening nut II is twisted to move upwards along the fastening bolt I until the fastening nut II presses against the connecting support frame, completing the installation and positioning of the air source heat pump. The box door is opened, and the fruits and vegetables to be dried are placed on the wire mesh rack. Multiple layers of wire mesh racks are installed inside the hot air drying box, increasing the amount of fruits and vegetables dried at one time and improving work efficiency. After the fruits and vegetables are placed, the box door is closed, causing the two L-shaped support frames on the top side of the box door to extend to both sides of the hot air drying box. The tension springs below the support plates on both sides of the hot air drying chamber pull the insert-type connecting rod through the positioning holes on the L-shaped support frame to position the chamber door. Then, the air source heat pump is started, and the output hot air is delivered to the distribution duct through the flexible connecting pipe. The distribution duct then disperses the hot air to multiple spray pipes. The hot air entering the spray pipes is dispersed and sprayed upward through multiple nozzles. The fruits and vegetables placed on the material conveying mesh belt are dried by hot air. The moisture generated during the drying process is discharged through the exhaust throttle valve on the inner wall of the top of the hot air drying chamber. After drying, the chamber door is opened and the dried fruits and vegetables are taken out. If the equipment needs to be disassembled, the fastening components can be reversed to remove the air source heat pump from the U-shaped positioning support frame.

[0027] Beneficial effects: In this utility model, the vegetable and fruit dryer that is easy to disassemble and assemble can use a positioning mechanism to lock the U-shaped locking strip with the U-shaped positioning support frame, thereby supporting the installation of the air source heat pump and making it easy to disassemble the air source heat pump. After the U-shaped locking strip is locked with the U-shaped positioning support frame, the fastening components on both sides can be used to position and brake the U-shaped locking strip, thereby enabling stable installation of the air source heat pump.

[0028] In this utility model, the vegetable and fruit dryer that is easy to disassemble and assemble can be equipped with a multi-layer mesh frame in the hot air drying box through a support mechanism, which can increase the amount of fruits and vegetables dried at one time and improve work efficiency.

[0029] In this utility model, the vegetable and fruit dryer that is easy to disassemble and assemble can, through a dispersion mechanism, disperse hot air into multiple spray pipes after being transported to the diversion conduit through the flexible connecting pipe and the material conveying pipe. The hot air entering the spray pipes can be dispersed and sprayed upward through multiple spray holes. Then, the hot air can be used to dry the fruits and vegetables placed on the material conveying mesh belt with hot air through the material conveying mesh belt.

[0030] In this invention, the air source heat pump is easy to disassemble and assemble, reducing maintenance costs and difficulty; the material conveying mesh belt provides stable transmission and avoids slippage; hot air is evenly dispersed and sprayed out through the diversion duct and spray pipe, improving drying quality and consistency; the door panel is easy to position, the overall structure is optimized, improving production efficiency and ensuring drying effect.

Specifically, the positioning mechanism consists of a U-shaped positioning support frame 8 fixedly installed on one side of the hot air drying oven 1, and a U-shaped locking strip 10 fixedly installed on the air source heat pump 9. The U-shaped locking strip 10 is placed inside the U-shaped positioning support frame 8, achieving a locking fit between the two. Fastening components are connected to the top of both sides of the U-shaped locking strip 10. These components include a support fixing ring 11 rotatably connected to the top of one side of the U-shaped locking strip 10, located outside the U-shaped positioning support frame 8.

The fastening nut II 14 is tightly fitted to the bottom of the connecting support frame 12. During installation, after securing the U-shaped locking strip 10 inside the U-shaped positioning support frame 8, rotate the fastening bolt I 13 to the vertical position so that it passes through the connecting support frame 12. Then, twist the fastening nut II 14 to move it upward along the fastening bolt I 13 until it presses against the connecting support frame 12, thus completing the installation and positioning of the air source heat pump 9. For disassembly, reverse the above steps to remove the air source heat pump 9 from the U-shaped positioning support frame 8.

[0043] A flexible connecting pipe 15 is fixedly installed at the air outlet of the air source heat pump 9, and one side of the flexible connecting pipe 15 extends into the hot air drying box 1.

[0044] The hot air drying box 1 is equipped with a support mechanism, which includes multiple mesh frames 25.

[0045] A dispersion mechanism is installed inside the hot air drying chamber 1, including a diversion duct 16 fixedly installed inside the hot air drying chamber 1. A material conveying pipe 17 is fixedly installed through one side of the inner wall of the diversion duct 16, and the material conveying pipe 17 is tightly inserted and snapped into the flexible connecting pipe 15. Multiple spray pipes 18 are fixedly installed through the bottom inner wall of the diversion duct 16 at equal intervals. One end of the spray pipe 18 extends below the material conveying mesh belt 22. Multiple spray holes corresponding to the positions of the material conveying mesh belt 22 are opened at equal intervals on the top inner wall of the spray pipe 18. The same mounting plate is fixedly installed at one end of the multiple spray pipes 18, and the mounting plate is fixedly installed inside the hot air drying chamber 1. The hot air output by the air source heat pump 9 is transported to the diversion duct 16 through the flexible connecting pipe 15 and the material conveying pipe 17, and then dispersed to the multiple spray pipes 18. The hot air entering the spray pipes 18 is dispersed and sprayed upward through the multiple spray holes, and the fruits and vegetables placed on the material conveying mesh belt 22 are dried by hot air. The moisture generated during drying is discharged through the exhaust throttle valve 3.

[0046] Two L-shaped support frames 4 are symmetrically fixedly installed on the top of one side of the door panel 2. The two L-shaped support frames 4 extend to both sides of the hot air drying oven 1.

[0049] The air source heat pump 9 consists of an evaporator, a compressor, a condenser, and a throttling device.

[0050] Operating principle: By continuously completing the thermodynamic cycle of refrigerant evaporation (absorbing heat, low-temperature, low-pressure liquid becoming low-temperature, low-pressure gas) → compression (low-temperature, low-pressure gas becoming high-temperature, high-pressure gas) → condensation (releasing heat, high-temperature, high-pressure gas becoming high-temperature, high-pressure liquid) → throttling (high-temperature, high-pressure liquid becoming low-temperature, low-pressure liquid → re-evaporation), unusable low-grade heat in the environment is transferred into usable high-grade heat.

[0051] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 19 are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
