Detailed Implementation

[0025] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0026] Example 1:

[0027] In this embodiment, as Figures 1-5 As shown, a tumbling drying device includes a housing 101 and a drum 102 rotatably disposed inside the housing 101. Suitable food types are placed inside the drum 102, allowing the food to fully contact the hot air and achieve a drying effect. A temperature and humidity sensor can also be installed inside the housing 101 for real-time monitoring of the internal temperature and humidity. Both ends of the drum 102 are rotatably connected to side plates 103. One side plate 103 has an inlet 104 for placing food ingredients, and the bottom of the drum 102 has an outlet 10. 5. For placing and discharging food raw materials, ensuring the overall practicality of the device, a door 106 is provided on the side of the box 101 near the feed inlet 104. A heating mechanism 200 for continuously conveying hot air is provided on the top and inner side of the box 101. A tumbling mechanism 300 for driving the drum 102 to rotate is provided inside the box 101. Before using the tumbling drying device, check whether the device can be used normally, then place a number of materials into the drum 102, and start the corresponding components through the controller 110 to put the device into the ready-to-use state.

[0028] Among them, such as Figures 1-4As shown, the heating mechanism 200 includes a heating box 201. Several heating wires 202 are evenly installed inside the heating box 201. A cover 203 is hinged to the top of the heating box 201. A sealing gasket is provided at the connection between the cover 203 and the heating box 201 to prevent heat loss. The heating wires 202 can be inspected by opening the cover 203. A fan 204 is fixedly installed on one side of the heating box 201. An air inlet pipe 205 is provided at the input end of the fan 204, and a dustproof screen is provided at the air inlet pipe 205. The output end of the fan 204 extends to the heating box 201. Inside the housing 101, a wind chamber 206 is provided on the side wall. Several air outlets are evenly distributed on the surface of the wind chamber 206 to facilitate the circulation of hot air. An air inlet pipe 207 extending into the wind chamber 206 is installed on the other side of the heating box 201. The heating wire 202 is connected to the controller 110 through a cable and can convert electrical energy into heat energy. The fan 204 delivers dust-free air into the heating box 201. The hot air that has absorbed heat energy enters the wind chamber 206 through the air inlet pipe 207 and then circulates and distributes to the inside of the roller 102 through several air outlets.

[0029] Among them, such as Figures 2-5 As shown, the tumbling mechanism 300 includes symmetrically arranged fixing frames 301 inside the housing 101. The fixing frames 301 are all fixedly installed on the top wall of the housing 101. The roller 102 is rotatably positioned between the two fixing frames 301 to increase overall stability and provide a fixing effect. A gear ring 302 is fixedly installed on the outer wall of the roller 102, driving the roller 102 to rotate as a whole. A gear 303 is meshed on one side of the gear ring 302. Both the gear 303 and the gear ring 302 are made of materials with high temperature resistance and low coefficient of thermal expansion, such as stainless steel or special alloys. To reduce deformation and wear at high temperatures, a heat dissipation structure, such as air cooling or heat sinks, can be added to one side of gear 303 depending on the actual environment. Gear 303 is connected to the inner wall of housing 101 via a bracket. One side of gear 303 is fixedly connected to the output end of first motor 304. First motor 304 is fixedly mounted on the bracket. When first motor 304 is started, it drives gear 303 to rotate, which in turn drives gear 303 to mesh and transmit power, so that drum 102 is in a tumbling state, increasing the contact area and range between food and hot air, and improving drying efficiency.

[0030] Among them, such as Figure 2 , Figure 3 and Figure 5 As shown, the circumferential cross-section of the roller 102 is set as a trapezoid, which allows food raw materials to be piled up inside the roller 102, increasing the tumbling space and facilitating subsequent feeding operations. The surface of the roller 102 is evenly distributed with a number of through holes 107 for hot air to pass through. The diameter of the through holes 107 is smaller than the diameter of the food raw materials and larger than the diameter of the air outlet on the surface of the air chamber 206, so that hot air can smoothly enter the inside of the roller 102 through the through holes 107 and facilitate the falling off of dust and other impurities.

[0031] Among them, such as Figures 2-5 As shown, the bottom of the roller 102 is also provided with a rotating mechanism 400 to avoid clogging the through hole 107. The rotating mechanism 400 includes a rotating rod 401 rotatably connected to the side plate 103. One end of the rotating rod 401 extends to the outside of the roller 102 and is fixedly connected to the output end of the second motor 402. The second motor 402 is fixedly connected to the housing 101. The other end of the rotating rod 401 also extends to the outside of the housing 101 and is connected to the fixing frame 301 through the limiting block 403. Several flipping blades 404 are fixedly installed on the outside of the rotating rod 401 to further disperse the food raw materials. The second motor is then started. 402, which in turn drives the rotating rod 401 and the rotating blade 404 to rotate, and can adjust the speed and direction of the first motor 304 and the second motor 402, so that the rotating blade 404 is also in a tumbling state relative to the drum 102, avoiding some food from accumulating at the bottom of the drum 102 for a long time, and improving drying efficiency. The shape of the rotating blade 404 is adapted to the shape of the drum 102. A brush 405 is provided on one side of the rotating blade 404. The brush 405 is in contact with the inner wall of the drum 102, so that the brush 405 can wipe the inner wall of the drum 102 and avoid clogging.

[0032] Among them, such as Figure 2 and Figure 3 As shown, an exhaust pipe 108 is provided on one side of the housing 101 to discharge the moisture generated during drying. The other end of the exhaust pipe 108 is connected to an exhaust device (not shown in the figure), which is existing technology.

[0033] Example 2:

[0034] The difference from Example 1 is that, as in Example 1, Figures 2-5 As shown, the side plates 103 are all connected to the fixing frame 301 by reinforcing rods, which restricts the position of the side plates 103 and increases the stability of the connection between the side plates 103 and the rotating rod 401.

[0035] Among them, such as Figures 2-4 As shown, a receiving hopper 109 is slidably provided at the bottom of the box 101. The receiving hopper 109 is connected to the box 101 by several bolts, which facilitates the subsequent centralized processing of food raw materials, moisture, impurities, etc.

[0036] Among them, such as Figure 1 As shown, a controller 110 is fixedly installed on one side of the housing 101. The controller 110 can be selected from Schneider Zelio or Mitsubishi FX3U series according to the actual production environment. The controller 110 is electrically connected to the first motor 304 and the second motor 402. The controller 110 is connected to the electrical components of the device to facilitate the transmission of commands and control of the device operation.

[0037] Among them, such as Figure 1 As shown, support members 111 are symmetrically arranged at the lower end of the box 101. The support members 111 can be set as support bases or casters, which serve to support the tumbling drying device and facilitate movement.

[0038] In use, a number of food ingredients are placed into the drum 102 through the feed inlet 104. The first motor 304 is started to drive the gear 303 to rotate. With the assistance of the two fixed frames 301, the gear ring 302 and the drum 102 rotate stably. The surface of the drum 102 is provided with a number of through holes 107 to facilitate the circulation of hot air and to keep the food in a tumbling state, increasing the contact area between the food and the hot air. At this time, the fan 204 and the heating wire 202 are also in the starting state, which can heat the dust-free air from the outside and deliver it into the chamber 101 to dry the food ingredients from the outside to the inside. Impurities in the drying process can be discharged through the through holes 107 and fall into the receiving hopper 109. After the drying operation is completed, the receiving hopper 109 is slid out to collect the impurities. The dried food ingredients are then collected through the cleaned receiving hopper 109.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
