Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0042] Existing interlayer drying devices usually use a multi-layer stacking method for internal drying. The hot air of the drying is circulated internally to evaporate the water. However, there are limitations in the evaporation process. Usually, only the upper and lower layers have a faster drying speed. The middle part is easily blocked, resulting in a slow evaporation efficiency. In order to solve the above problems, this case proposes the following technical solutions:

[0043] See also Figures 1 to 8 The present invention provides a food production equipment and production process technical solution: its structure includes: a drying chamber 2 and a hot air box 3, the hot air box 3 is installed on both sides of the drying chamber 2, and a movable door panel 4 is provided at the front end of the drying chamber 2, the door panel 4 and the drying chamber 2 form a closed cavity, a controller 5 is installed on the surface of the drying chamber 2, and a drying layer 1 is installed inside the drying chamber 2, the drying layer 1 is located in the middle of the hot air box 3, the drying layer 1 includes a positioner 11, a turning frame 12, and a containing tank 13, the containing tank 13 is nested inside the turning frame 12, and the positioner 11 controls the turning frame 12 to move up and down;

[0044] The flip frame 12 includes a driver 121 and a frame 122. The driver 121 is movably connected to the frame 122. The driver 121 includes a first motor 211. A base frame 212 is installed on the main shaft of the first motor 211. A rotatable gear box 214 is provided on one side surface of the base frame 212. The gear box 214 is connected to the first motor 211. A driving pulley 215 and an auxiliary roller 216 are provided on the outside of the gear box 214. The motor inside the gear box 214 drives the driving pulley 215 to rotate and drives the frame 122 to move horizontally. The auxiliary rollers 216 are distributed on both sides of the frame 122 and slide with the frame 122.

[0045] When in use, the structure of this device includes a drying layer 1, which is installed inside a drying chamber 2 and is dried by hot air boxes 3 on both sides of the drying chamber 2. A controller 5 is provided on the top of the drying chamber 2, which is used to control the internal temperature of the hot air boxes 3. During the drying process, the door panel 4 is closed to form a closed space inside the drying chamber 2, thereby accelerating the circulation of hot air.

[0046] The positioner 11 of the drying layer 1 is installed on the surface of the drying chamber 2. A movable and rotatable turning frame 12 and a receiving groove 13 are set at the front end of the positioner 11. The receiving groove 13 is engaged with the surface of the turning frame 12. Food can be placed on the surface of the receiving groove 13 and then placed inside the turning frame 12 for drying.

[0047] The specific structure of the flip frame 12 includes a driver 121, which is used to flip the frame 122. The driver 121 includes a first motor 211 for driving. The first motor 211 is fixed in the middle of the base frame 212. The main shaft penetrates the middle of the base frame 212 and is connected to the outer shell of the gear box 214. The gear box 214 is equipped with a gear inside, which is connected to the driving pulley 215. In order to synchronously drive the upper and lower frames 122 to move, two driving pulleys 215 are provided, which are respectively connected to the gears inside the gear box 214. In order to make the upper and lower driving pulleys 215 rotate in opposite directions, a connecting gear is added between one of the gears to change the rotation direction of the driving pulley 215.

[0048] In order to ensure that the frame 122 runs smoothly between the driving pulleys 215, auxiliary rollers 216 and supporting beams 217 are provided adjacent to the driving pulleys 215. The auxiliary rollers 216 are arranged in groups of two, nested in the upper and lower surfaces of the frame 122 and nested with the slide rails 224 of the frame 122. In order to further improve the supporting strength, the auxiliary slide rails 225 of the frame 122 also cooperate with the groove body of the supporting beam 217 to avoid collapse, and can also provide stable support during rotation.

[0049] The structure of the containing tank 13 includes a top net 131 and a clamping part 133. The top net 131 and the clamping part 133 can be folded to form a net frame to fix the food up and down to prevent it from falling when turning over. The top net 131 and the bottom net 132 are provided with a clamping part 133. Specifically, when the containing tank 13 is placed in the turning rack 12, the clamping part 133 will follow the movement of the turning rack 12 and roll and clamp with the auxiliary roller 216, and then lock it. In order to facilitate removal after drying, a release groove 134 is provided on one side of the clamping part 133, and the food is released through the release groove 134. The release method is that when the release groove 134 moves to the auxiliary roller 216, it is staggered with the release groove 134, and the clamping is released.

[0050] The structure of the frame 122 includes a limiting groove 221 nested with the receiving groove 13. The limiting groove 221 is installed on one side of the mesh plate 222 and a side frame 223 is set on the other side. A slide rail 224 that cooperates with the auxiliary roller 216 is installed adjacent to the side frame 223. The mesh plate 222 is provided with an auxiliary slide rail 225 at the bottom where the side frame 223 is installed to cooperate with the supporting beam 217. The mesh plate 222 has a double width and can be easily disassembled and installed.

[0051] The structure of the positioner 11 includes a vertical slide rail 111 fixed to the surface of the drying bin 2, and the vertical slide rail 111 cooperates with the slide groove 213 on the side of the base frame 212. A second motor 112 is fixed on the top of the vertical slide rail 111, and the flip frame 12 is lifted by the second motor 112. Specifically, the main shaft gear of the second motor 112 is engaged with the bar-shaped external teeth of the gear handle 113, and the bottom end of the gear handle 113 is connected to the first motor 211 of the top flip frame 12. A synchronous ring 114 is installed on the surface of the first motor 211 of the flip frame 12. The synchronous ring 114 has an annular structure, and the top ring body is fixedly connected to the shaft rod surface of the opposite first motor 211, such as by welding or bolting. The inner wall of the ring body at the bottom of the synchronous ring 114 is slidably connected to the shaft rod of the adjacent first motor 211. When the top first motor 211 is pulled upward, the synchronous ring 114 lifts the bottom first motor 211.

[0052] When the gap needs to be reduced, the gear handle 113 moves downward, the first motor 211 moves downward, and the limiting beam 115 supports the falling first motor 211. When the bottom first motor 211 contacts the limiting beam 115, the upper first motor 211 is stacked one after another, thereby reducing the gap between the turning frames 12 and facilitating operation during loading. When the second motor 112 is lifted, the gap between the turning frames 12 is increased to avoid collision during turning and improve the circulation effect of hot air.

[0053] The working process of this device:

[0054] s1: The temperature of the hot air box 3 is set by the controller 5, the top net 131 is opened, the food to be processed is placed on the surface of the bottom net 132, and the top net 131 is locked inside the frame 122;

[0055] s2: The gear box 214 drives the receiving groove 13 to move, so that the auxiliary roller 216 contacts the clamping portion 133 and reduces the overlapping range of the upper and lower receiving grooves 13;

[0056] s3: Close the door panel 4 and start the heating pipe and fan inside the hot air box 3 to circulate hot air;

[0057] s4: After drying for a while, the second motor 112 starts, pulling up the gear handle 113. After pulling up, the synchronizer ring 114 increases the gap between the drivers 121. The gear box 214 drives the drive pulley 215 to move the flip frame 12 and the container 13 toward the middle until the upper and lower containers 13 overlap.

[0058] s5: The first motor 211 is started to drive the gear box 214 to rotate, so that the turning frame 12 and the receiving tank 13 are turned over. After the turning over, the gear box 214 drives the driving pulley 215 again to unfold the turning frame 12 and the receiving tank 13.

[0059] s6: After drying is completed, the driver 121 of the flipping frame 12 drives the frame body 122 and the receiving tank 13 to flip. During the flipping process, the internal motor of the gear box 214 drives the frame body 122 to move horizontally toward the middle. When the door panel 4 is opened, the driving pulley 215 is located at the release groove 134, releasing the limit on the clamping part 133. At this time, the receiving tank 13 can be disassembled, and then the next round of drying can be started.

[0060] The improved device uses the positioner 11 to adjust the gap between the turning frame 12, which facilitates the efficiency of loading and can increase the drying gap. The heat flow covers a larger area. The positioner 11 and the turning frame 12 cooperate with the driving pulley 215 and the slide rail 224 to enable the frame 122 to move left and right, reducing the range of turning. When the left and right movements are staggered, the overlapping areas can be replaced, and the drying effect is better.

[0061] By utilizing the cooperation between the clamping portion 133, the release groove 134 and the auxiliary roller 216, the reversible top net 131 is pressed when the clamping portion 133 is pressed to prevent it from falling off. When the drying is completed, the auxiliary roller 216 is located at the top of the release groove 134, releasing the limit on the containing tank 13, so that it can be quickly replaced without the operation being too complicated.

[0062] The above only describes the basic principles and preferred embodiments of the present invention. Those skilled in the art may make many changes and improvements based on the above description, and these changes and improvements should fall within the scope of protection of the present invention.

[0063] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
