Description
Technical Field
[0001] This invention relates to the field of dehydration and drying equipment technology, specifically to a dehydration and drying equipment for treating kitchen waste. Background Technology
[0002] Food waste refers to waste generated in daily life, food processing, and catering services. It includes discarded vegetable leaves, leftover food, fruit peels, eggshells, tea dregs, bones, etc. Its main sources are household kitchens, restaurants, hotels, canteens, markets, and other food-related industries. Food waste contains extremely high levels of moisture and organic matter, making it easily perishable and producing a foul odor. Furthermore, its high moisture content makes it bulky and heavy, hindering transportation. Therefore, most food waste is now treated with drying equipment to evaporate the moisture, making it less prone to decay and easier to transport.
[0003] For example, Chinese patent publication number "CN216814900U" discloses "a food waste drying device". Its main structure includes a reaction chamber with an open top, a feed cover and a discharge cover that can be opened and closed on the reaction chamber, a heating element and a stirring mechanism inside the reaction chamber, a condensing plate enclosed at the open part of the reaction chamber, a cooling element inside the condensing plate, the condensing plate being inclined, and a drain pipe located at the lower end of the condensing plate, the drain pipe passing through the reaction chamber and extending outside the reaction chamber. This food waste drying device, by using a condensing plate, a cooling element and a drain pipe, allows the water vapor formed by the evaporation of water vapor in the food waste to condense into water droplets on the condensing plate and be discharged from the reaction chamber through the drain pipe, thereby reducing the air humidity in the reaction chamber and improving the efficiency of the food waste drying device in heating and evaporating food waste.
[0004] However, the aforementioned kitchen waste drying equipment uses an internal stirring mechanism to stir the kitchen waste inside the reaction chamber to ensure the flowability of the drying gas. However, the stirring mechanism can easily cause some fruits and vegetables to be crushed, resulting in the waste being in a tiny accumulation state that is difficult to clean. At the same time, since the drying gas and condensation area are both located in the reaction chamber, it is difficult for high-temperature steam to be discharged in a timely manner, thus affecting the drying efficiency.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] Please see Figure 1 and Figure 2 A dehydration and drying device for treating kitchen waste includes a bottom support base plate 1 that provides bottom support. The driven pulley 29 is linked to a drive motor with a drive pulley mounted on the end of a rotor via a synchronous belt. The bottom docking plate 35 is connected to the exhaust port of a blower. The two terminals 38 are connected to the power output terminal of a current controller that can control the current through wires. By simultaneously turning on the drive motor, the current controller, and the blower, the functions of flipping, heating, and gas flow can be realized.
[0029] To enable the flipping drive function for kitchen waste, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4A driven tilting mechanism 2 needs to be set up. Its structure includes a horizontal drum 21 with a hollowed-out circumference that can store kitchen waste, a side guard plate 25 that can be detachably installed at the port of the horizontal drum 21 and can drive the horizontal drum 21 to rotate, a horizontal rotating shaft 27 set at one end of the side guard plate 25 and can drive the side guard plate 25 to rotate, and a bushing 28 installed on the shaft of the horizontal rotating shaft 27 through a bearing. One of the side guard plates 25 is removed with a wrench, and then the kitchen waste to be dried is put into the drying cavity 23. Then the side guard plate 25 is closed. The start of the drive motor will drive the horizontal drum 21 to rotate in a direction through the driven pulley 29. The kitchen waste inside the horizontal drum 21 will be in a state of continuous tilting. Tilting can make all the kitchen waste move to the outermost area, so that all the kitchen waste can be dried by gas. At the same time, the high temperature steam formed by gas dehydration will be discharged in time through the vent 22 above, thereby realizing the tilting drive function of kitchen waste.
[0030] For details regarding the specific structure of the driven flipping mechanism 2, please refer to [link / reference]. Figure 3 and Figure 4 It also includes a drying cavity 23 located inside the horizontal drum 21 and open at both ends. The horizontal drum 21 has multiple ventilation holes 22 on its circumference connecting to the external space and the drying cavity 23. The horizontal drum 21 has a recessed limiting groove 24 at each of the two open ends of the drying cavity 23. One end face of the side guard plate 25 has a limiting chuck 26 integrally formed with it and capable of engaging with the limiting groove 24.

A horizontal rotating shaft 27 with an integral structure is provided. A bushing 28 capable of relative rotation is installed on the shaft body of the horizontal rotating shaft 27 via a bearing. A driven pulley 29 is fitted at the end of one of the horizontal rotating shafts 27. The cross-sectional shape of the limiting groove 24 is consistent with the cross-sectional shape of the limiting chuck 26, both being polygonal structures. The cross-sectional dimensions of the limiting groove 24 are adapted to the cross-sectional dimensions of the limiting chuck 26. During installation, the driven pulley 29 is linked to a drive motor with a drive pulley installed at the end of a rotor via a synchronous belt.
[0031] To achieve the function of heating the gas and thus producing a high-temperature drying effect, please refer to [link / reference needed]. Figure 1 , Figure 2 , Figure 5 and Figure 6A heating gas guiding mechanism 3 needs to be set up. Its structure can seamlessly contact the bottom of the horizontal drum 21 and the hollow cover 31 with a hollow internal structure, the heating hollow shell 34 set at the bottom of the hollow cover 31 and with a hollow internal structure, and the resistance rod 39 installed at the axis of the heating hollow shell 34 and capable of heating the flowing gas. The injection of current will cause the resistance rod 39 to generate a high temperature phenomenon. At this time, the gas generated by the blower will move upward around the resistance rod 39. At this time, the flowing gas will be heated and the heated gas will form a high temperature gas. The high temperature gas will first enter the gas reserved cavity 32 and accumulate. Then, the high temperature gas will enter the drying cavity 23 through the vent 22 located below, thereby drying and dehydrating the turned kitchen waste.
[0032] For details regarding the specific structure of the heating gas guiding mechanism 3, please refer to [link / reference]. Figure 5 and Figure 6 It also includes a gas-reserving cavity 32 disposed inside the contact hollow cover 31 and having an open top. The bottom of the contact hollow cover 31 is fixedly installed above the bottom support base plate 1 by a support rod. The top of the contact hollow cover 31 is provided with an arc-shaped placement surface 33 for placing the horizontal roller 21. A heating hollow shell 34 integrally formed with the bottom center of the contact hollow cover 31 is provided. The bottom of the heating hollow shell 34 is provided with a bottom docking plate 35 integrally formed with the bottom. The interior of the heating hollow shell 34 is provided with a top-connected gas-reserving cavity 32 and a bottom... The heating cavity 36 has an open end structure. The bottom and top ends of the resistance rod 39 are fixedly installed on the inner circumference of the heating hollow shell 34 by a conductive bracket 37. A terminal 38 is installed on one side of each of the two conductive brackets 37. The arc-shaped placement surface 33 can fit seamlessly on the bottom circumference of the horizontal roller 21, and the gas reserved cavity 32 is in a closed state. During installation, the bottom docking plate 35 is docked with the exhaust port of a blower, and the two terminal 38 are connected to the power output terminal of a current controller that can control the current magnitude through wires.
[0033] To reduce the frictional resistance of the horizontal drum 21 during rotation, please refer to... Figure 1 , Figure 2 , Figure 7 and Figure 8Two buffer-type pressure-reducing mechanisms 4 need to be set up. Their structure includes a longitudinal hollow rod 41 fixedly installed on the upper surface of the bottom support base plate 1 and having a hollow internal structure; a piston plate 47 placed inside the longitudinal hollow rod 41 and capable of longitudinal movement under liquid pressure; an arc-shaped support tile 411 capable of supporting the bushing 28; and a helical spring 49 placed between the piston plate 47 and the bushing 28 and providing elastic support. When the horizontal roller 21 rotates, it needs to overcome the frictional force between its bottom and the contact surface of the hollow cover 31. This frictional force and the horizontal roller... The downward weight of the cylinder 21 is proportional to the overall weight. A certain amount of liquid is injected into the liquid compensation channel 45 through the liquid injection device. At this time, the liquid causes the piston plate 47 to move upward, thereby changing the distance between the piston plate 47 and the built-in movable plate 48. Finally, the upward elastic force of the helical spring 49 on the arc-shaped support tile 411 increases. The arc-shaped support tile 411 can reduce the downward weight of the horizontal roller 21, thereby reducing the frictional resistance of the horizontal roller 21 during rotation. The user can control the magnitude of the frictional force by injecting the amount of liquid according to the actual situation.
[0034] For details regarding the specific structure of the buffer-type pressure-reducing mechanism 4, please refer to [link / reference]. Figure 7 and Figure 8 It also includes a bottom fixing plate 42 integrally disposed at the bottom of the longitudinal hollow rod 41 and fixedly installed on the upper surface of the bottom support base plate 1. The longitudinal hollow rod 41 has a longitudinal movable cavity 43 inside. The interior of the longitudinal hollow rod 41 is connected to a liquid flow hole 44 at the bottom end of the longitudinal movable cavity 43. A liquid compensation channel 45 connected to the outside space and equipped with a valve is provided on one side of the liquid flow hole 44. A piston plate 47 capable of moving along the longitudinal movable cavity 43 is placed inside the longitudinal movable cavity 43. An internal movable plate 48 capable of moving along the longitudinal movable cavity 43 is placed directly above the piston plate 47 in the longitudinal movable cavity 43. A compressed helical spring 49 is placed between the stopper plate 47 and the built-in movable plate 48. The top end of the longitudinal hollow rod 41 is provided with a rod body through hole 46 that connects the external space and the top end of the longitudinal movable cavity 43. A longitudinal movable rod 410 that passes through the rod body through hole 46 is fixedly installed on the upper surface of the built-in movable plate 48. An arc-shaped support tile 411 that is adapted to the bushing 28 is installed at the bottom end of the longitudinal movable rod 410. The cross-sectional shape of the rod body through hole 46 is consistent with the cross-sectional shape of the longitudinal movable rod 410, both being polygonal structures. Furthermore, the cross-sectional dimensions of the rod body through hole 46 are adapted to the cross-sectional dimensions of the longitudinal movable rod 410.
[0035] In use, the driven pulley 29 is connected to a drive motor with a drive pulley mounted on the rotor end via a synchronous belt. The bottom connecting plate 35 is then connected to the exhaust port of a blower. The two terminals 38 are connected to the power output terminal of a current controller that can control the current magnitude via wires. Simultaneously, the drive motor, current controller, and blower are turned on. One side panel 25 is removed using a wrench, and the kitchen waste to be dried is placed into the drying cavity 23. The side panel 25 is then closed. The start of the drive motor causes the horizontal drum 21 to rotate directionally via the driven pulley 29. The injection of current causes the resistance rod 39 to generate high current. During the warming process, the gas generated by the blower moves upward around the resistance rod 39. The flowing gas is heated, forming high-temperature gas. This high-temperature gas first enters the gas pre-reserved cavity 32 and accumulates. Then, it enters the drying cavity 23 through the lower vent 22, thereby drying and dehydrating the tumbling kitchen waste. The kitchen waste inside the horizontal drum 21 is constantly tumbling, which allows all the kitchen waste to move to the outermost area, ensuring that all the kitchen waste is dried by the gas. At the same time, the high-temperature steam generated by the gas dehydration is discharged in time through the upper vent 22.
