[0002] Fruit is an indispensable part of daily life. Different regions produce different types of fruit, and making dried fruit extends the shelf life of fruit and allows people to taste the flavors of various fruits from different places. Currently, the most common method for making dried fruit is the drying method, which involves heating and dehydrating the fruit to make dried fruit.
[0003] For example, Chinese patent CN106839723A discloses a continuous dryer that completes continuous drying in the drying chamber by continuous feeding through a conveyor belt; after feeding is completed, the feed inlet can be closed to reduce heat loss and achieve energy saving.
[0004] However, with only one conveyor line transporting materials, fruits of different sizes are dried for the same amount of time during the drying process, which can easily lead to under-drying of large fruits or over-drying of small fruits.
[0005] Based on this, the present invention designs a continuous drying device to solve the above problems. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-2 A continuous drying device includes a drying chamber 1, a material distribution mechanism 2, and a conveying mechanism 3;
[0030] The drying box 1 is symmetrically equipped with air supply modules on its front and rear sides; the drying box 1 is equipped with a material distribution mechanism 2 for conveying fruits according to their size; the drying box 1 is symmetrically equipped with two sets of conveying mechanisms 3 for moving fruits inside the drying box 1.
[0031] like Figure 2 As shown, the material distribution mechanism 2 includes a material distribution module 21 and an adjustable material blocking module 22. The material distribution module 21 is installed on the drying box 1, and the adjustable material blocking module 22 is symmetrically installed on the drying box 1.
[0032] The air supply module includes a fan 11, a manifold box 12, and a conveying pipe 13; the conveying pipe 13 is fixedly installed in a rectangular array on the drying box 1; the outer side of the conveying pipe 13 is fixedly installed on the manifold box 12, and the fan 11 is fixedly installed on the manifold box 12; the drying box 1 and the manifold box 12 are connected through the conveying pipe 13.
[0033] The two sets of conveying mechanisms 3 have different conveying speeds.
[0034] In this embodiment, when the continuous drying equipment is working normally, the adjustable baffle module 22 is adjusted according to the characteristics of the fruit and the required feeding speed, thereby adjusting the speed at which the fruit falls from the distribution module 21 onto the conveying mechanism 3. Regularly shaped fruits, such as longan, are fed into the distribution module 21, which separates the fruit according to size, allowing smaller and larger fruits to move to the conveying mechanisms 3 on both sides. The conveying mechanism 3 moves the fruit within the drying chamber 1, where it is heated. Then, the fan 11, the manifold 12, and the conveying pipe 13 work together... Accelerating the airflow within the drying chamber 1 removes moisture from the fruit on the conveying mechanism 3. The fruit is continuously conveyed through the coordination of the material distribution module 21, the adjustable baffle module 22, and the conveying mechanism 3. Continuous drying of the fruit is achieved through the coordination of the drying chamber 1, the fan 11, the manifold box 12, and the conveying pipe 13. During this process, the conveying speed of the conveying mechanisms 3 on both sides is adjusted according to the size of the fruit, resulting in different residence times for fruits of different sizes within the drying chamber 1. This ensures the drying effect for fruits of different sizes and avoids incomplete drying of large fruits or over-drying of small fruits.
[0035] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figure 4 and Figure 5As shown, the material distribution module 21 includes a material distribution rack 212. A feeding port 211 is provided on the top of the drying box 1, and an inclined material distribution rack 212 is fixedly installed at the feeding port 211. Material distribution grooves 213 are evenly distributed at equal intervals on the material distribution rack 212. The width of the material distribution groove 213 at the higher part of the material distribution rack 212 is smaller than the width of the material distribution groove 213 at the lower part of the material distribution rack 212.
[0036] The material distribution module 21 also includes a material feeding plate 214, which is symmetrically fixedly installed on the drying oven 1; the material feeding plate 214 is aligned with the material distribution rack 212.
[0037] The adjustable baffle module 22 includes a limiting mounting bracket 221, a baffle plate 223 and an adjustment module. The limiting mounting bracket 221 is symmetrically fixedly installed inside the drying chamber 1. A limiting groove 222 is opened on the inner side of the limiting mounting bracket 221, and the baffle plate 223 slides within the limiting groove 222. The adjustment module is installed on the drying chamber 1 and the baffle plate 223.
[0038] The adjustment module includes an adjustment screw 224 and an adjustment block 225. The lower end of the adjustment screw 224 is rotatably mounted on the baffle plate 223, and the upper end of the adjustment screw 224 passes through the drying box 1 and is fixedly connected to the adjustment block 225. The adjustment screw 224 is threadedly connected to the drying box 1 through a threaded sleeve.
[0039] like Figures 3-5 As shown, the conveying mechanism 3 includes multiple sets of conveying modules and collecting modules, which are installed on the drying box 1 and the junction box 12; the multiple sets of conveying modules are vertically staggered.
[0040] The conveying module includes conveying rollers 31, a transmission module 32, a conveying motor 33, and a conveying belt 34. Two conveying rollers 31 are rotatably mounted inside the drying chamber 1. The two conveying rollers 31 are fixedly connected to the power input end and the power output end of the transmission module 32, respectively. The conveying motor 33 is fixedly mounted on the manifold box 12, and the output end of the conveying motor 33 passes through the manifold box 12 and the drying chamber 1 and is fixedly connected to one of the conveying rollers 31. The conveying belt 34 is sleeved on the outside of the two conveying rollers 31 and the material collection module, and the conveying rollers 31 and the conveying belt 34 are driven by friction. The conveying belt 34 has evenly spaced and uniformly spaced material drop holes 35.
[0041] The transmission module 32 is configured as a synchronous belt conveyor, and both the power input end and the power output end of the transmission module 32 are synchronous pulleys;
[0042] The material collection module includes a guide roller 36 and a material collection plate 37. The conveyor belt 34 is sleeved on the outside of the guide roller 36 and the material collection plate 37. The guide roller 36 is in rolling connection with the lower side of the conveyor belt 34, and the material collection plate 37 does not contact the conveyor belt 34.
[0043] In this embodiment, when the dispensing mechanism 2 and the conveying mechanism 3 are working normally, rotating the adjusting block 225 drives the adjusting screw 224 to rotate, thereby changing the length of the adjusting screw 224 inside the drying box 1 through the thread between the adjusting screw 224 and the drying box 1, thereby changing the height of the baffle plate 223 inside the drying box 1. The baffle plate 223 moves vertically under the limiting action of the limiting groove 222, changing the distance between the baffle plate 223 and the discharge plate 214; thereby adjusting the size of the opening for the fruit to fall from the discharge plate 214 and the baffle plate 223, and changing the speed at which the fruit falls.
[0044] Fruits are placed onto the inclined sorting rack 212. Under the influence of gravity, the fruits roll down the sorting rack 212. During this process, the fruits move from the narrower part of the sorting trough 213 to the wider part of the sorting trough 213. Smaller fruits first fall through the sorting trough 213 onto the feed plate 214 on one side. Larger fruits move to the wider part of the sorting trough 213 and then fall onto the feed plate 214 on the other side. Then, under the influence of gravity, the fruits fall along the feed plate 214 onto the upper conveyor belt 34.
[0045] The conveyor motor 33 drives two conveyor rollers 31 to rotate through the transmission module 32. The conveyor rollers 31 drive the conveyor belt 34 to circulate outside the conveyor rollers 31 and guide rollers 36, so that the fruit on the conveyor belt 34 moves. The flowability is ensured by the discharge hole 35, so that the bottom of the fruit can be ventilated as it moves with the conveyor belt 34, thereby improving the drying speed. At the same time, the fruit on the upper conveyor belt 34 falls onto the adjacent lower conveyor belt 34 after it reaches the end and continues to move. During this process, the dust and debris on the surface fall onto the collecting plate 37 through the discharge hole 35. The collecting plate 37 collects the debris and dust, preventing the debris and dust from falling into the inside of the conveyor belt 34.
[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
