[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0027] The embodiment of the present application provides a fruit and vegetable waste dehydration and reduction device, which can solve the problem that in the related art, in the existing fruit and vegetable waste dehydration and reduction device during use, the heat distribution is uneven, and some waste may have excessive moisture remaining due to insufficient drying, affecting the dehydration and reduction effect.

[0028] Please refer to Figures 1 - 3, a fruit and vegetable waste dehydration and reduction device includes: a frame 1, a silo 2 for waste input is arranged on the frame 1, a crushing mechanism 3 is arranged at the bottom of the silo 2, the crushing mechanism 3 is used for crushing fruit and vegetable waste, a screw conveyor 4 is arranged at the bottom of the crushing mechanism 3, and the outlet of the screw conveyor 4 is communicated with a drying mechanism 5. The screw conveyor 4 is used to send the crushed fruit and vegetable waste into the drying mechanism 5;

[0029] The drying mechanism 5 includes a drying box 51, three groups of conveyors 52, three groups of hot air supply components 53 and several electric heating tubes 54. The three groups of conveyors 52 are sequentially arranged inside the drying box 51 and are used to convey the fruit and vegetable waste from top to bottom in sequence. The three groups of hot air supply components 53 are sequentially arranged above the corresponding conveyors 52 and are used to dry the fruit and vegetable waste on the conveyors 52. The several electric heating tubes 54 are arranged inside the drying box 51.

[0030] Input waste: Fruit and vegetable waste is first put into the silo 2 located on the frame 1.

[0031] Crush waste: The crushing mechanism 3 at the bottom of the silo 2 starts to work, crushing large pieces or whole fruit and vegetable waste into smaller pieces or particles for subsequent processing.

[0032] Convey waste: The crushed fruit and vegetable waste is conveyed to the drying mechanism 5 through the screw conveyor 4. The rotational movement of the screw conveyor 4 ensures the stable and continuous conveyance of the waste.

[0033] Dry waste: The three groups of conveyors 52 are sequentially arranged inside the drying box 51, conveying the crushed fruit and vegetable waste layer by layer from top to bottom. The three groups of hot air supply components 53 respectively correspond to the three groups of conveyors 52, drying the fruit and vegetable waste on the conveyors 52 by blowing hot air. The electric heating tubes 54 provide additional heat inside the drying box 51 to assist the hot air supply components 53 in improving the drying effect.

[0034] With the continuous movement of the conveyor 52, the fruit and vegetable waste passes through the drying box 51 layer by layer from top to bottom, undergoes multiple hot air dryings, and finally achieves the purpose of dehydration and reduction.

[0035] By means of crushing and multi-layer hot air drying, the evaporation rate of water in the fruit and vegetable waste is greatly accelerated, and the dehydration efficiency is improved. The setting of the multi-layer conveyors 52 and hot air supply components 53 enables the fruit and vegetable waste to be evenly heated inside the drying box 51, avoiding the problem of uneven drying.

[0036] At the same time, it can work continuously on the fruit and vegetable waste, continuously process the fruit and vegetable waste, and meet the large-scale and continuous processing requirements.

[0037] Such as Figure 5As shown, it should be noted that in this embodiment, the three groups of conveyors 52 convey in sequence from top to bottom, and the three groups of conveyors 52 are staggered left and right, a discharge port is opened on the drying box 51, and one end of the conveyor 52 at the bottom extends to the discharge port.

[0038] The three groups of conveyors 52 are sequentially conveyed from top to bottom, and they are staggered left and right inside the drying box 51. This design not only optimizes the drying process, but also improves the drying efficiency and uniformity.

[0039] Specifically, when the fruit and vegetable garbage enters the drying mechanism 5, it will first fall onto the top conveyor 52. As the conveyor 52 operates, the fruit and vegetable garbage will move to the lower right and fall onto the conveyor 52 of the next layer. Since the conveyors 52 are staggered left and right, the fruit and vegetable garbage will present a Z-shaped moving track on the conveyor of each layer, which helps to increase the contact area and time between the fruit and vegetable garbage and the hot air, thereby improving the drying effect.

[0040] After multiple layers of drying, the fruit and vegetable garbage will eventually reach the conveyor 52 at the bottom of the drying box 51. Since one end of the bottom conveyor 52 extends to the discharge port, the dried fruit and vegetable garbage can be directly discharged from the discharge port.

[0041] In this embodiment, an exhaust pipe is provided on the drying box 51 , and a drainage pipe is provided at the bottom of the drying box 51 .

[0042] The exhaust duct provided on the drying box 51 plays a role in dehumidification.

[0043] During the drying process, as the moisture in the fruit and vegetable waste evaporates, a large amount of hot and humid air will be generated inside the drying box 51, and the hot and humid air will be discharged to the outside of the drying box 51 through the exhaust pipe, thereby reducing the humidity inside the drying box 51, which is conducive to further accelerating the drying process of the fruit and vegetable waste.

[0044] The drain pipe at the bottom of the drying box 51 is used to discharge liquid waste generated during the drying process.

[0045] Since the fruit and vegetable garbage releases some water and liquid during the crushing and drying process, these liquid wastes will affect the drying effect and the normal operation of the equipment if they are not discharged in time. The design of the drain pipe ensures that these liquid wastes can be discharged smoothly, keeping the drying box 51 dry and clean.

[0046] Preferably, Figure 4 and Figure 5As shown, in this embodiment, the hot air supply component 53 includes a main pipeline 531 disposed inside the drying box 51. A number of distribution pipes 532 are provided on the main pipeline 531. A number of nozzles 533 are provided at the bottom of the distribution pipes 532. A number of the nozzles 533 are located above the corresponding conveyor 52. One end of the main pipeline 531 is communicated with an external hot air supply pipeline.

[0047] The hot air supply component 53 in this embodiment realizes a fast and uniform drying effect by providing hot air to the fruit and vegetable waste.

[0048] Hot air supply: One end of the main pipeline 531 is communicated with an external hot air supply pipeline. The hot air generated by an external heat source such as a hot blast stove, a steam heater, etc. is sent into the main pipeline 531 through the external hot air supply pipeline.

[0049] Hot air distribution: A number of distribution pipes 532 are provided on the main pipeline 531. These distribution pipes 532 evenly distribute the hot air in the main pipeline 531 above the conveyor 52. A number of nozzles 533 are provided at the bottom of each distribution pipe 532. The function of these nozzles 533 is to spray the hot air onto the fruit and vegetable waste on the conveyor 52 in a more uniform and finer manner.

[0050] Contact between hot air and fruit and vegetable waste: As the conveyor 52 moves, the fruit and vegetable waste is conveyed layer by layer from top to bottom in the drying box 51. During the conveying process, the hot air is evenly sprayed onto the fruit and vegetable waste through the nozzles 533, and heat exchange is carried out with the moisture in the fruit and vegetable waste, so that the moisture evaporates quickly.

[0051] Hot air circulation and discharge: During the drying process, part of the humid hot air will be generated as the moisture in the fruit and vegetable waste evaporates. These humid hot air can be discharged through the exhaust pipe on the drying box 51, and at the same time, new hot air is continuously supplemented through the hot air supply pipeline, forming a cycle process.

[0052] The conveyor 52 in this embodiment includes driving wheels oppositely arranged inside the drying box 51. A transmission belt is arranged between the two driving wheels on the outside. A number of the electric heating tubes 54 are located in the middle of the corresponding transmission belt. A power source is provided on the drying box 51. The power source is connected to any one of the driving wheels and is used to drive the driving wheel to rotate. Among them, the power source includes a driving motor and a reducer.

[0053] The conveyor in this embodiment is used to convey the crushed fruit and vegetable waste layer by layer from top to bottom inside the drying box 51.

[0054] The conveyor 2 mainly consists of two driving wheels oppositely arranged inside the drying box 51. A transmission belt is arranged between the two driving wheels on the outside, forming a closed conveying path. The electric heating tubes 54 are located in the middle position of the corresponding transmission belt and are used to provide additional heat to the fruit and vegetable waste.

[0055] A power source is provided on the drying oven 51, and the power source includes a driving motor and a speed reducer. The driving motor is connected to any one of the driving wheels through the speed reducer and is used to drive the rotation of the driving wheel. When the driving motor is started, after the deceleration of the speed reducer, the driving wheel starts to rotate, thereby driving the conveyor belt to move.

[0056] It should be noted that the conveyor belt is a stainless steel mesh conveyor belt.

[0057] The design of the stainless steel mesh conveyor belt enables the hot air to easily penetrate the conveyor belt and directly act on the fruit and vegetable waste, thereby accelerating the drying speed and improving the drying efficiency.

[0058] Since the hot air can uniformly penetrate the stainless steel mesh conveyor belt, the fruit and vegetable waste can be subjected to a more uniform hot air action during the conveying process, thereby avoiding the problem of uneven drying caused by local overheating or overcooling.

[0059] Specifically, as Figure 3 shown, in this implementation scheme, the crushing mechanism 3 includes a crushing chamber 31, two crushing rollers 32 and a second driving member 33. The crushing chamber 31 is communicated with the bottom of the material bin 2. The two crushing rollers 32 are relatively rotatably arranged inside the crushing chamber 31. The second driving member 33 is connected to the crushing roller 32 and is used to drive the crushing roller 32 to rotate. Among them, the second driving member 33 includes a speed reducer arranged on the crushing chamber 31. A driving motor is arranged on the speed reducer. The output shaft of the driving motor is connected to the input shaft of the speed reducer. The output shaft of the speed reducer is connected to any one of the crushing rollers. The other ends of the two crushing rollers 32 extend to the outside of the crushing chamber 31, and gears are arranged at the other ends of the two crushing rollers 32, and the two gears are meshed with each other.

[0060] The main function of the crushing mechanism 3 is to crush the input fruit and vegetable waste to facilitate subsequent drying treatment.

[0061] The crushing chamber 31 is communicated with the bottom of the material bin 2 to ensure that the fruit and vegetable waste input from the material bin 2 can smoothly enter the crushing chamber 31. The two crushing rollers 32 are relatively rotatably arranged inside the crushing chamber 31 to form a certain gap for crushing the fruit and vegetable waste.

[0062] The output shaft of the driving motor is connected to the input shaft of the speed reducer. The speed is reduced and the torque is increased through the speed reducer, and then the power is transmitted to any one of the crushing rollers 32. Since the other ends of the two crushing rollers 32 both extend to the outside of the crushing chamber 31 and are provided with meshing gears, when one crushing roller 32 is driven to rotate, the other crushing roller 32 will also rotate through gear transmission, forming a relatively rotating state.

[0063] After the fruit and vegetable waste enters the crushing chamber 31 from the silo 2, two relatively rotating crushing rollers 32 will clamp the fruit and vegetable waste in the middle and crush it. Since the surface of the crushing rollers 32 is provided with crushing teeth or crushing knives, the fruit and vegetable waste can be more effectively crushed into smaller particles or fragments.

[0064] As Figure 4 shown, in this embodiment, the screw conveyor 4 includes a housing 41, a screw conveyor rod 42 and a first driving member 43. The screw conveyor rod 42 is rotatably arranged inside the housing 41. The first driving member 43 is connected to the screw conveyor rod 42 and is used to drive the screw conveyor rod 42 to rotate. A motor heating rod 44 is arranged inside the screw conveyor rod 42. The housing 41 is provided with a feed inlet communicating with the crushing chamber 31 and a discharge outlet communicating with the drying box 51. The first driving member 43 includes a driving motor and a reducer.

[0065] The main function of the screw conveyor 4 is to continuously and stably transport the fruit and vegetable waste crushed by the crushing mechanism 3 into the drying box 51 for subsequent processing.

[0066] The screw conveyor rod 42 is arranged inside the housing 41 to form a spiral conveying channel. The driving motor is connected to the screw conveyor rod 42 through a reducer to provide rotational power for the screw conveyor rod 42. The motor heating rod 44 is arranged inside the screw conveyor rod 42 to provide additional heat for the transported fruit and vegetable waste and preheat the fruit and vegetable waste.

[0067] In actual operation, the fruit and vegetable waste crushed by the crushing mechanism 3 enters the housing 41 of the screw conveyor 4 from the feed inlet. Driven by the first driving member 43, the screw conveyor rod 42 starts to rotate and pushes the fruit and vegetable waste forward along the spiral conveying channel. Due to the rotation of the screw conveyor rod 42 and the spiral shape of the conveying channel, the fruit and vegetable waste can move forward continuously and stably. At the same time, the motor heating rod 44 generates heat and transfers it to the transported fruit and vegetable waste through the wall of the screw conveyor rod 42, thus realizing the heating function. The fruit and vegetable waste transported by the screw conveyor 4 finally enters the drying box 51 from the discharge outlet for subsequent processing.

[0068] In this embodiment, a drain pipe is arranged at the bottom of the housing 41, and a filter screen is arranged inside the drain pipe

[0069] The screw conveyor 4 adds a drainage and filtration function on the original basis, which is used to drain the excess water in the fruit and vegetable waste during the transportation process and prevent solid residues from entering the drainage system.

[0070] Under the rotational drive of the screw conveyor rod 42, the fruit and vegetable waste enters the housing 41 of the screw conveyor 4 from the feed inlet and moves forward along the spiral conveying channel. During the conveying process, due to the rotation of the screw conveyor rod 42 and the gravity of the fruit and vegetable waste itself, the excess moisture will be squeezed out and flow to the bottom of the housing 41. When the moisture flows into the drain pipe, it will first pass through a filter screen. The filter screen can effectively intercept the solid residues in the fruit and vegetable waste and prevent them from entering the drainage system. After being filtered by the filter screen, only the clean moisture can be discharged through the drain pipe.

[0071] In the present embodiment, the silo 2 is provided with a discharge port 21 communicating with the crushing chamber 31. A plurality of drain holes 22 are opened inside the silo 2, and a drain pipe is provided at the bottom of the silo 2 at the bottom of the drain holes.

[0072] The silo 2, as the feeding part of the fruit and vegetable waste dehydration and reduction equipment, realizes the preliminary drainage and pretreatment of the fruit and vegetable waste before it enters the crushing mechanism.

[0073] The silo 2 is used to receive the input fruit and vegetable waste and guide it into the crushing chamber 31.

[0074] A plurality of drain holes 22 are opened inside the silo 2. The function of these drain holes 22 is to allow the excess moisture in the fruit and vegetable waste to flow out naturally under the action of gravity. The setting positions of the drain holes 22 are considered in view of the accumulation and flow of the fruit and vegetable waste in the silo 2 to ensure that the moisture can be discharged smoothly.

[0075] At the same time, the fruit and vegetable waste enters the crushing chamber 31 through the discharge port 21 under the guidance of the silo 2 for subsequent crushing and dehydration treatment.
