[0038] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0039] like Figure 1 As shown, the present application provides a drying machine 1, comprising:

[0040] The box body 11 has a feed inlet 111 on its upper cover, through which the sheets to be dried enter the box body 11. The box body 11 has a first end 112 and a second end 113 along a first direction, and the feed inlet 111 is disposed near the first end 112 of the box body 11;

[0041] A mesh conveyor belt 12 is disposed in the box body 11. The mesh size of the mesh conveyor belt 12 is smaller than the size of the sheet to be dried. The mesh conveyor belt 12 is used to run along a first direction. There is a discharge gap between the end of the mesh conveyor belt 12 along the first direction and the side wall of the second end 113 of the box body 11.

[0042] The drying assembly 13 is disposed at a first end 112 of the housing 11 along a first direction. The drying assembly 13 is communicated with the housing 11 to supply hot air into the housing 11 .

[0043] In this embodiment, the box body 11 is a box body 11 with a rectangular cross section, and the box body 11 includes a box cover and a body, the box cover is arranged on the body, and a feed port 111 is arranged on the box cover near the first end 112 of the box body 11, and the mesh conveyor belt 12 is arranged below the upper cover, and there is a gap between the upper cover, so that the product to be dried entering from the feed port 111 will fall on the mesh conveyor belt 12, and the mesh conveyor belt 12 has mesh holes, and the size of the mesh holes is smaller than the size of the product to be dried, so that the product to be dried will not fall through the mesh holes on the mesh conveyor belt 12. The drying component 13 is a structure for blowing hot air, so that the product to be dried can be dried by hot air. The product to be dried can be food or other products that need to be dried.

[0044] The present application provides a drying machine 11, comprising a housing 11, a mesh conveyor belt 12 and a drying assembly 13. The mesh conveyor belt 12 is arranged in the housing 11 and is extended along the length direction of the housing 11, that is, extended along the first direction. The drying assembly 13 is arranged at the first end 112 of the housing 11 along the first direction. The housing 11 also includes an upper cover, on which a feed port 111 is arranged, so that the sheets to be dried can enter the housing 11 through the feed port 111, and then fall onto the mesh conveyor belt 12, and can move along the first direction driven by the mesh conveyor belt 12. When the products to be dried are transmitted along the conveyor belt, the drying assembly 13 arranged at the first end 112 of the housing 11 along the first direction supplies hot air into the housing 11. Since the mesh conveyor belt 12 has a mesh, the hot air of the drying assembly 13 can pass through the mesh conveyor belt 12 and be fully mixed with the products to be dried, so that the products to be dried can be dried during the transmission process. When the mesh conveyor belt 12 drives the products to be dried to the end of the mesh conveyor belt 12 along the first direction, there is a unloading gap between the end of the mesh conveyor belt 12 and the side wall of the second end 113 of the box body 11 along the first direction, so that the products to be dried that have been dried will enter the unloading gap under the action of the mesh conveyor belt 12 to facilitate subsequent unloading.

[0045] Therefore, the dryer 1 provided by the present application can drive the product to be dried to run along the first direction through the arrangement of the mesh conveyor belt 12, and during the operation, the hot air supplied by the drying component 13 can pass through the mesh conveyor belt 12 and be fully mixed with the product to be dried, so as to achieve drying of the product to be dried. The problem that the hot air cannot be fully mixed with the sheet to be dried is avoided, and the drying quality of the sheet to be dried is improved.

[0046] like Figure 1 As shown, in the embodiment of the present application, it also includes:

[0047] The discharge hopper 14 is disposed below the box body 11 and communicates with the area of ​​the box body 11 corresponding to the discharge interval. A discharge port 141 is disposed at the bottom of the discharge hopper 14 for discharging the sheets to be dried.

[0048] In this embodiment, the discharge hopper 14 is a funnel-type discharge hopper 14, the side of the funnel-type discharge hopper 14 with a larger cross section is connected to the box body 11, and the side with a smaller cross section is provided with the discharge hopper 14 below. The box body 11 has a bottom plate adapted to the upper cover, the area of ​​the bottom plate corresponding to the grid conveyor belt 12 has a plate body, and the area of ​​the bottom plate of the box body 11 corresponding to the discharge interval has a hollow area, so that the product to be dried can enter the discharge hopper 14 from the hollow area.

[0049] In this embodiment, the dryer 1 includes a box body 11, a mesh conveyor belt 12, a drying component 13 and a discharge hopper 14. The upper cover of the box body 11 is provided with a feed port 111. The product to be dried enters from the feed port 111 and falls onto the mesh conveyor belt 12 in the box body 11. The drying component 13 supplies hot air into the box body 11. The hot air is fully mixed with the product to be dried through the mesh of the mesh conveyor belt 12. During the drying process, the mesh conveyor belt 12 drives the product to be dried to run in the first direction. During the operation, the hot air always passes through the mesh. The conveyor belt 12 dries the products to be dried. When the mesh conveyor belt 12 transfers the products to be dried to the end, the dried products to be dried will fall from the unloading gap between the mesh conveyor belt 12 and the side wall of the second end 113 of the box body 11, and enter the unloading hopper 14. The unloading hopper 14 is provided with a unloading port 141 at the bottom away from the box body 11, so that the dried products to be dried will be directly discharged from the unloading port 141 of the unloading hopper 14, and the unloading efficiency is high, thereby solving the problem of inconvenient discharge of the products to be dried after drying.

[0050] like Figure 1 As shown, in the embodiment of the present application, it also includes:

[0051] The adjusting plate 15 is arranged in the box body 11, close to the feed port 111, and between the feed port 111 and the second end 113 of the box body 11.

[0052] In this embodiment, the adjustment plate 15 is a plate-like structure, and the adjustment plate 15 is connected to the upper cover by a lead screw extending in the vertical direction, so that the adjustment plate 15 can rise or fall in the vertical direction. The adjustment plate 15 is extended in a second direction perpendicular to the first direction and the vertical direction, and the length of the adjustment plate 15 in the second direction is the same as the length of the inside of the box body 11 in the second direction, so that the products to be dried falling from the feed port 111 to the grid conveyor belt 12 can be blocked. The feed port 111 provided on the upper cover is located between the first end 112 of the box body 11 and the adjustment plate 15.

[0053] In this embodiment, the adjustment plate 15 is located above the mesh conveyor belt 12, and there is a first gap between the adjustment plate 15 and the mesh conveyor belt 12. The product to be dried that enters the box body 11 from the feed port 111 will fall onto the mesh conveyor belt 12, and after being transferred to the adjustment plate 15 on the mesh conveyor belt 12, it will be blocked to a certain extent by the action of the adjustment plate 15. The product to be dried in the first gap between the adjustment plate 15 and the mesh conveyor belt 12 will continue to be transferred along with the mesh conveyor belt 12 through the first gap, while the product to be dried that is higher than the first gap will not continue to be transferred through the first gap, but will be transferred later, so that the thickness of the product to be dried can be adjusted by adjusting the gap between the adjustment plate 15 and the mesh conveyor belt 12, avoiding the problem of uneven drying caused by excessive thickness of the product to be dried, and also avoiding the problem of low drying efficiency caused by too small thickness.

[0054] like Figure 1 As shown, in the embodiment of the present application, it also includes:

[0055] The driving member 16 is disposed on the outer wall of the box body 11 . The driving member 16 is electrically connected to the grid conveyor belt 12 to drive the grid conveyor belt 12 to run along a first direction and to control the running speed of the grid conveyor belt 12 .

[0056] In this embodiment, the driving member 16 may be a reduction motor.

[0057] In this embodiment, the driving member 16 is electrically connected to the grid conveyor belt 12, so that after the driving member 16 is turned on, it can be used to drive the grid conveyor belt 12 to run in a first direction, and the driving member 16 can also control the running speed of the grid conveyor belt 12, so that the grid conveyor belt 12 can drive the products to be dried to move in the first direction at a suitable speed, thereby controlling the running speed of the products to be dried, so that the products to be dried can achieve the best drying effect at the best speed.

[0058] like Figure 1 As shown, in the embodiment of the present application, it also includes:

[0059] The moisture detection component 17 is arranged on the upper cover and near the end of the mesh conveyor belt 12, and is used to detect the moisture content of the sheets to be dried on the mesh conveyor belt 12 to obtain the moisture content.

[0060] In this embodiment, the moisture detection component 17 may include a probe, which is inserted into the product to be dried on the mesh conveyor belt 12, so that the moisture content of the product to be dried can be tested; the moisture detection component 17 may also be an infrared detection device, which sends an infrared signal to the product to be dried on the mesh conveyor belt 12, so that the moisture content of the product to be dried can be tested. The moisture detection component 17 has a display screen for displaying the moisture content obtained by the detection, so that the user can confirm the drying status of the product to be dried according to the moisture content displayed on the display screen.

[0061] like Figure 1 As shown, in the embodiment of the present application, it also includes:

[0062] The central controller 18 is connected to the moisture detection component 17 and the driving component 16 respectively, so as to receive the moisture content and control the driving component 16 to drive the running speed of the grid conveyor belt 12 according to the moisture content.

[0063] In this embodiment, the dryer 1 includes a box body 11, a mesh conveyor belt 12, a drying component 13, a discharge hopper 14, an adjustment plate 15, a driving member 16, a moisture detection component 17 and a central controller 18. A mesh conveyor belt is arranged in the box body 11. A drying component 13 is arranged at a first end 112 of the box body 11 along a first direction, which is used to transmit hot air into the box body 11 to achieve drying of the products to be dried on the mesh conveyor belt 12 in the box body 11. The arrangement of the mesh conveyor belt 12 allows the hot air to pass through the mesh conveyor belt 12 and be fully mixed with the products to be dried to achieve drying of the products to be dried. A moisture detection component 17 is arranged outside the box body 11. The moisture detection component 17 is used to detect the moisture content of the product to be dried transported by the grid conveyor belt 12 to the end. The moisture detection component 17 is connected to the central controller 18 to transmit the moisture content to the central controller 18. The central controller 18 compares and analyzes the moisture content. The central controller 18 is also connected to the driving member 16, so as to control the driving member 16 to adjust the transmission speed of the grid conveyor belt 12 according to the moisture content after the comparison and analysis, so as to change the running time of the product to be dried on the grid conveyor belt 12 to extend or shorten the drying time, so that the moisture content of the product to be dried detected again meets the preset moisture content to achieve the best drying efficiency.

[0064] like Figure 1 As shown, in the embodiment of the present application, it also includes:

[0065] The stacking detection component 19 is arranged on the side wall of the discharge hopper 14, and is used to detect the stacking height of the sheets to be dried in the discharge hopper 14. The stacking detection component 19 is connected to the central controller 18 to transmit the detected stacking height to the central controller 18. When the stacking height is higher than the preset height, the central controller 18 will alarm.

[0066] In this embodiment, the accumulation detection component 19 can be a probe extending into the inner wall of the discharge hopper 14 to detect the height of the products to be dried in the discharge hopper 14, or it can be an infrared detection device to detect the height of the products to be dried by infrared rays.

[0067] In this embodiment, a stacking detection component 19 is provided on the side wall of the discharge hopper 14, which is used to detect the height of the products to be dried accumulated in the discharge hopper 14. After the stacking detection component 19 detects the height of the products to be dried in the discharge hopper 14, the height information will be transmitted to the central controller 18. After the height of the products to be dried in the discharge hopper 14 is higher than the preset height, the central controller 18 will alarm so that the operator can promptly know that the products to be dried in the discharge hopper 14 are too high. When the stacking height reaches the preset upper limit, the central controller 18 can control the dryer 1 to stop and wait for manual inspection to avoid the problem of stacking caused by too much products to be dried in the discharge hopper 14.

[0068] In the embodiment of the present application, the central controller 18 is also connected to the adjustment plate 15 to control the rise or fall of the adjustment plate 15 according to the stacking height.

[0069] In this embodiment, after the central controller 18 receives the information that the stacking detection component 19 detects the height of the products to be dried in the discharge hopper 14, it will adjust the height of the adjustment plate 15 according to the height information. When the height is too high, the adjustment plate 15 can be controlled to descend to slow down the drying speed of the products to be dried. When the height is low, the adjustment plate 15 can be controlled to rise to speed up the drying speed of the products to be dried.

[0070] In the embodiment of the present application, a valve is provided at the discharge port 141 of the discharge hopper 14 to control the discharge speed.

[0071] In this embodiment, the valve may be a manual valve or an electrically controlled valve, and the valve may adjust the degree of opening of the discharge port 141, thereby controlling the discharge speed to meet user needs.

[0072] In the embodiment of the present application, the valve is an electrically controlled valve, and the central controller 18 is also connected to the valve to control the opening degree of the valve according to the stacking height.

[0073] In this embodiment, the central controller 18 is connected to both the valve and the adjusting plate 15, so that after receiving the stacking height information, the speed of the products to be dried entering the discharge hopper 14 can be controlled by controlling the height of the adjusting plate 15, and the speed of the products to be dried discharged from the discharge hopper 14 can be controlled by controlling the opening degree of the valve, thereby controlling the height of the products stacked in the discharge hopper 14 from both the entry and discharge directions, thereby improving the adjustment speed.
