TECHNICAL FIELD
[0001] The application relates to the technical field of food processing equipment, in particular to a melon, fruit and vegetable uniform temperature drying treatment equipment. BACKGROUND
[0002] With the improvement of food preservation technology, more and more surplus fresh vegetables, melons and fruits can be preserved by food preservation technology. Among many food preservation technologies, the uniform temperature drying technology is a low-cost technical solution. However, the uniform temperature drying technology has relatively large difficulty in temperature regulation and heat distribution. This results in a low yield in the process of uniform temperature drying of fresh vegetables, melons and fruits, which greatly reduces the economic benefits of uniform temperature drying of fresh vegetables, melons and fruits. Therefore, it is necessary to propose a melon, fruit and vegetable uniform temperature drying treatment equipment to solve the problem of large difficulty in temperature regulation and heat distribution of the traditional uniform temperature drying treatment equipment. CONTENT OF THE INVENTION

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0024] This application provides a uniform temperature drying equipment for fruits and vegetables.
[0025] like Figure 1 As shown in one embodiment of this application, a fruit and vegetable uniform temperature drying equipment includes a conveyor belt 100, a protective cover 200, an electric heating device 300, a first blower 400, and a second blower 500.
[0026] The conveyor belt 100 includes a mesh ring belt 110 and a drive shaft 120. The mesh ring belt 110 is sleeved on the outer peripheral surface of the drive shaft 120, and the inner peripheral surface of the mesh ring belt 110 abuts against the outer peripheral surface of the drive shaft 120.
[0027] The protective cover 200 includes a first flow channel 210, a second flow channel 220, and a third flow channel 230. The first flow channel 210 and the third flow channel 230 are interconnected, and the second flow channel 220 and the third flow channel 230 are interconnected. The conveyor belt 100 is disposed between the first flow channel 210 and the third flow channel 230, and the second flow channel 220 is disposed at the top end of the conveyor belt 100.
[0028] The electric heating device 300 is disposed in the inner cavity of the second flow channel 220.
[0029] The first blower 400 is disposed between the first flow channel 210 and the second flow channel 220. The air inlet of the first blower 400 is disposed close to the electric heating device 300, and the air outlet of the first blower 400 is disposed close to the first flow channel 210.
[0030] The second blower 500 is disposed between the second flow channel 220 and the third flow channel 230. The air inlet of the second blower 500 is disposed near the electric heating device 300, and the air outlet of the second blower 500 is disposed near the third flow channel 230.
[0031] This application relates to a uniform temperature drying device for fruits and vegetables, which uses a mesh belt 110 to carry fruits and vegetables through a uniform temperature drying process. Since the conveyor belt 100 is located inside the protective cover 200, the mesh belt 110 can receive uniformly heated airflow from the first flow channel 210 and the third flow channel 230. Using this uniformly heated airflow for drying fruits and vegetables improves the yield rate. The main reason for this improved yield rate is the relatively uniform temperature of the high-temperature airflow. The mesh belt 110 increases the heating area of the fruits and vegetables, thereby reducing drying time, preventing uneven heating, and preventing prolonged roasting. Specifically, the electric heating device 300 located inside the second flow channel 220 heats the air. The first blower 400 directs the hot air from the second flow channel 220 to the first flow channel 210, and the second blower 500 directs the hot air from the second flow channel 220 to the third flow channel 230.
[0032] like Figure 2 As shown, in one embodiment of this application, the mesh ring 110 includes a plurality of transverse strips 111 and a plurality of longitudinal strips 112. Each of the transverse strips 111 is parallel to each other. The distance between any two adjacent transverse strips 111 is the same. The ends of the same longitudinal strip 112 are connected. Each of the longitudinal strips 112 is parallel to each other. The distance between any two adjacent longitudinal strips 112 is the same. The transverse strips 111 are fixedly connected to each of the longitudinal strips 112.
[0033] Specifically, the horizontal stripes 111 and the vertical stripes 112 intersect to form a grid pattern. The area of each grid square is determined by the area of the fruit or vegetable slice. The area of each grid square can actually be the distance between two adjacent horizontal stripes 111 or the distance between two adjacent vertical stripes 112.
[0034] The connection of the two ends of the same vertical strip 112 enables the transfer of fruits and vegetables, allowing them to move inside the protective cover 200.
[0035] Because the mesh ring 110 has gaps, the bottom surface of the fruits and vegetables can also receive high-temperature airflow.
[0036] like Figure 3 As shown, in one embodiment of this application, the protective cover 200 is provided with a first connecting hole 211 and a second connecting hole 231. The central axis of the first connecting hole 211 and the central axis of the second connecting hole 231 coincide with each other. The first connecting hole 211 is sleeved on the outer peripheral surface of the first end of the power shaft 120. The second connecting hole 231 is sleeved on the outer peripheral surface of the second end of the power shaft 120.
[0037] Specifically, the drive shaft 120, by closely adhering to the inner surface of the mesh ring belt 110, can achieve the rotation of the mesh ring belt 110 through friction, thereby driving the fruits and vegetables to move within the protective cover 200.
[0038] The central axis of the first connecting hole 211 and the central axis of the second connecting hole 231 coincide with each other. The power shaft 120 can be accommodated in the first connecting hole 211 and the second connecting hole 231 to realize the installation of the power shaft 120. The power shaft 120 can rotate around the central axis of the first connecting hole 211, thereby driving the mesh ring belt 110 to rotate.
[0039] like Figure 3 As shown, in one embodiment of this application, the power shaft 120 includes a first roller 121 and a second roller 122. The central axis of the first roller 121 is parallel to the central axis of the second roller 122. The central axis of the first roller 121 is perpendicular to the sidewall of the first flow channel 210. The central axis of the second roller 122 is perpendicular to the sidewall of the first flow channel 210. The first roller 121 is disposed in the inner cavity of the first connecting hole 211. The first roller 121 is disposed in the inner cavity of the second connecting hole 231. The second roller 122 is connected to a bracket 123. The bracket 123 is fixedly connected to the bottom end of the second flow channel 220.
[0040] Specifically, since the drying process needs to be maintained for a period of time, the mesh belt 110 needs to be of sufficient length, and the first roller 121 and the second roller 122 can support both ends of the mesh belt 110.
[0041] The second roller 122 is fixedly connected to the bottom end of the second flow channel 220 through the bracket 123, realizing the air support of the mesh ring belt 110 and ensuring that the mesh ring belt 110 can be fully exposed to the high temperature airflow.
[0042] like Figure 3 As shown, in one embodiment of this application, the conveyor belt 100 further includes a driver 124. The first roller 121 extends out of the protective cover 200 through a first connecting hole 211. The driver 124 is fixedly connected to the outer wall of the protective cover 200. The extended portion of the first roller 121 is connected to the driver 124.
[0043] Specifically, the first roller 121, as the active power transmission mechanism, needs to extend out of the protective cover 200, and the first roller 121 is connected to the driver 124 via a belt.
[0044] The first roller 121 extends out of the protective cover 200, which can reduce the chance of fruits and vegetables being contaminated.
[0045] like Figure 3As shown, in an embodiment of the present application, the first flow channel 210 includes a plurality of first air vents 212 and a plurality of second air vents 213. The center of each first air vent 212 is on a same straight line; define the straight line as a first standard line 214. The center of each second air vent 213 is on a same straight line; define the straight line as a second standard line 215. The first standard line 214 is parallel to the second standard line 215. The plane of the conveying material of the mesh belt 110 is disposed between the first standard line 214 and the second standard line 215. The first standard line 214 is parallel to the plane of the conveying material of the mesh belt 110. The second standard line 215 is parallel to the plane of the conveying material of the mesh belt 110.
[0046] Specifically, the hot air flow delivered by the first air vent 212 can dry the upper surface of the fruits and vegetables.
[0047] The hot air flow delivered by the second air vent 213 can dry the lower surface of the fruits and vegetables.
[0048] The center of each first air vent 212 is on the first standard line 214, which can achieve uniform and stable distribution of the hot air flow to the upper surface of the fruits and vegetables.
[0049] The center of each second air vent 213 is on the second standard line 215, which can achieve uniform and stable distribution of the hot air flow to the lower surface of the fruits and vegetables.
[0050] In an embodiment of the present application, the third flow channel 230 includes a plurality of third air vents 232 and a plurality of fourth air vents 233. The center of each third air vent 232 is on a same straight line; define the straight line as a third standard line 234. The center of each fourth air vent 233 is on a same straight line; define the straight line as a fourth standard line 235. The third standard line 234 is parallel to the fourth standard line 235. The plane of the conveying material of the mesh belt 110 is disposed between the third standard line 234 and the fourth standard line 235. The third standard line 234 is parallel to the plane of the conveying material of the mesh belt 110. The fourth standard line 235 is parallel to the plane of the conveying material of the mesh belt 110.
[0051] Specifically, the hot air delivered by the third air vent 232 can dry the upper surface of the fruits and vegetables.
[0052] The hot air delivered by the fourth air vent 233 can dry the lower surface of the fruits and vegetables.
[0053] The center of each third air vent 232 is on the third standard line 234, which can achieve uniform and stable distribution of the hot air flow to the upper surface of the fruits and vegetables.
[0054] The center of each fourth ventilation hole 233 is located at the fourth standard line 235, which can achieve uniform and stable distribution of hot airflow to the lower surface of fruits and vegetables.
[0055] High-yield fruit and vegetable drying can be achieved through the hot airflow through the first ventilation hole 212, the second ventilation hole 213, the third ventilation hole 232 and the fourth ventilation hole 233.
[0056] like Figure 3 As shown, in one embodiment of this application, the electric heating device 300 includes a power converter 310, an electronic speed controller 320, and a heating wire 330. The power converter 310 is electrically connected to alternating current. The power converter 310 is electrically connected to the electronic speed controller 320. The electronic speed controller 320 is electrically connected to the heating wire 330.
[0057] Specifically, the power converter 310 can be equipped with a switching power supply, such as the UHP-750 switching power supply.
[0058] The ESC 320 is an electronic speed controller that can adjust the output power of the power converter 310, thereby enabling the heating wire 330 to generate heat.
[0059] The heating wire 330 generates electric heat, which can heat the air in the second flow channel 220.
[0060] like Figure 3 As shown, in one embodiment of this application, the heating wire 330 is laid in the inner cavity of the second flow channel 220. The heating wire 330 is disposed at the bottom of the second flow channel 220. The heating wire 330 is disposed between the first blower 400 and the second blower 500.
[0061] Specifically, the heating wire 330 is disposed between the first blower 400 and the second blower 500, which facilitates the first blower 400 and the second blower 500 to guide the hot airflow in the second flow channel 220 into the first flow channel 210 and the third flow channel 230.
[0062] like Figure 1 As shown, in one embodiment of this application, the second flow channel 220 is provided with a ventilation hole 221. The ventilation hole 221 is located near the heating wire 330. The ventilation hole 221 is provided with an air filter device 222.
[0063] Specifically, the ventilation hole 221 is positioned close to the heating wire 330 to improve airflow and thus achieve high-flow-rate air heating. After the air is heated, pollutants and impurities are effectively reduced. At the same time, the air filter device 222 can also reduce the amount of pollutants and impurities.
[0064] Any combination of the technical features in the above-described embodiments can be made, and the method steps are not limited in execution order. For the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combination of the technical features does not exist in contradiction, it should be considered as within the scope of the present disclosure.
[0065] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
