Description

Technical Field

[0001] This utility model relates to the field of almond circulating drying and dehulling technology, specifically to an almond circulating drying and dehulling device. Background Technology

[0002] Almond kernels are rich in nutrients and are beneficial to human health. In recent years, the sales of almonds have increased dramatically. However, the traditional shelling of almonds still requires manual intervention, such as manual sorting, which is inefficient. Furthermore, the fact that shelled almonds cannot be dried in time greatly affects their taste.

[0003] Existing methods for shelling almonds involve crushing them. However, the hard shells can cause splashing during crushing, damaging machinery or workers, and making rapid drying difficult. For example, CN116473244B discloses an almond rolling shelling and screening device and method, which includes an outer shell with a feed hopper at one end. The bottom of the feed hopper extends into a screening mechanism movably connected inside the shell. The screening mechanism contains a screening hopper driven by a vibrating motor for gravity screening of almonds. A crushing mechanism is connected to the rear end of the screening mechanism. The crushing mechanism includes... The conveyor belt and variable-diameter rolling rollers crush almonds in sections. A screen plate with a vibrating motor is installed under the conveyor belt, extending to the discharge port at the end of the outer casing. A waste outlet is located below the screen plate. The device uses vibration screening to separate almonds by size, and the variable-diameter rolling rollers crush them in sections, ensuring that almonds of all sizes receive the appropriate rolling depth, guaranteeing rolling accuracy, improving product quality, and showing good development prospects. However, in this design, the hard outer casing may splash during the crushing process, potentially damaging or jamming the machine and affecting its service life.

[0004] Therefore, it is necessary to invent a circulating drying and shelling device for almonds to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a circulating drying and shelling device for almonds, in order to solve the problems of low shelling efficiency and the inability to dry the wet almonds after shelling in a timely manner.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An almond circulating drying and dehulling device includes a feed inlet, a conveyor belt, a dehulling mechanism, and a drying chamber. The feed inlet is prismatic, and its bottom corresponds to the initial end of the conveyor belt. The conveyor belt passes sequentially through the dehulling mechanism and the drying chamber. V-shaped inclined grooves are evenly arranged above the conveyor belt and installed on the side frame of the conveyor belt. The dehulling mechanism achieves synchronous rotation of pressure roller one, pressing roller and pressure roller two through a motor and sprocket transmission mechanism. The bottom of the dehulling mechanism is connected to a spray bar through an external water pipe. The spray bar is located directly above the pressing roller. Multiple heating wires are installed at the top of the drying chamber, and a sealed soft curtain is installed on the side of the outlet of the drying chamber.

[0007] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model improves the crushing of almond shells by designing multiple pressure rollers in the shelling mechanism and adding blades to the pressure rollers. At the same time, the multiple pressure rollers and crushing rollers can spray water mist on the almonds during operation, which effectively prevents the shells from splashing during crushing. 2. This utility model uses the operation of the rolling roller to drive the rotation of the gear set, which causes the crank connecting rod and the connecting rod to move within the limiting guide sleeve, thereby driving the swing plate to swing back and forth, increasing the rapid heat flow rate in the drying oven, and accelerating the rapid drying of the shelled and wetted almonds.

[0010] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0011] This utility model provides, for example Figures 1 to 5 The almond circulating drying and shelling equipment shown includes an inlet 1, a conveyor belt 2, a shelling mechanism 4, and a drying chamber 7. The inlet 1 is prismatic, and its bottom corresponds to the initial end of the conveyor belt 2. The conveyor belt 2 passes sequentially through the shelling mechanism 4 and the drying chamber 7. V-shaped inclined troughs 3 are evenly arranged above the conveyor belt 2 and installed on its side frame. The inclined troughs 3 are actually formed by two non-contacting long strips of sidewalls. The bottom of the two long strips of sidewalls forms an opening, allowing the almonds to contact the conveyor belt 2 after falling, thus enabling the almonds to be conveyed along with the conveyor belt 2. The shelling mechanism 4 uses a motor 6 and a sprocket drive mechanism to achieve synchronous rotation of pressure roller 1 401, crushing roller 403, and pressure roller 2 404. A spray rod 5 is connected to the bottom of the shelling mechanism 4 via an external water pipe, and the spray rod 5 is positioned directly above the crushing roller 403. Multiple heating wires 701 are installed at the top of the drying chamber 7, and a sealing soft curtain 8 is installed on the outlet side of the drying chamber 7.

[0012] When almonds are conveyed from the feed inlet 1 to the conveyor belt 2 and transported from left to right, they pass through the shelling mechanism 4 and are cut and crushed by the first pressure roller 401, the crushing roller 403, and the second pressure roller 404. At the same time, the shells are wetted while being crushed, which effectively prevents the shells from splashing when they are crushed. Finally, they enter the drying box 7 to dry.

[0013] Blades 402 are evenly mounted on the first pressure roller 401, and the positions of the blades 402 correspond to the positions of multiple V-shaped inclined grooves 3, which are made of silicone. The first pressure roller 401 and the second pressure roller 404 are identical in size and structure, and the second pressure roller 404 also has evenly mounted blades 402. The first pressure roller 401 and the second pressure roller 404 are respectively positioned on both sides of the crushing roller 403. A gear set 405 is mounted on the drive shaft of the crushing roller 403. One gear on the gear set 405 is eccentrically connected to a crank connecting rod 406, and a push rod 407 is rotatably connected to the end of the crank connecting rod 406. When the first pressure roller 401 is activated, the evenly distributed blades 402 on its surface cut open the almond shells. The shells are then crushed by the crushing roller 403, and finally, the second pressure roller 404 cuts open any remaining unshelled almonds, ensuring efficient shelling.

[0014] The inner side of the drying box 7 is equipped with a limiting guide sleeve 702. The push rod 407 passes through the outer end of the limiting guide sleeve 702 and is connected to a connecting rod 408. The top inner wall of the drying box 7 is connected to a swing plate 409 through a rotating shaft. The connecting rod 408 rotates and slides in a groove (not shown in the figure) opened on the side of the swing plate 409.

[0015] The swing plate 409 is positioned below the heating wire 701 and in the middle of the drying chamber 7.

[0016] The length of the limiting guide sleeve 702 is one-third of the length of the push rod 407, and the height of the limiting guide sleeve 702 is also at the middle position of the swing plate 409.

[0017] When the rolling roller 403 is started, it drives the gear set 405 to run, causing the push rod 407 to move back and forth laterally, which drives the swing plate 409 to swing continuously, so that the hot air in the drying box 7 can be circulated quickly, and water vapor can be discharged from the side of the drying box 7 inlet, thus accelerating the drying process.

[0018] During operation, the shelled almonds are first poured into the feed inlet 1 and continuously conveyed onto the conveyor belt 2. The almonds fall into each inclined chute 3. When they pass through the pressure roller 401, the hard shells are cut open. When they pass through the crushing roller 403, the shells are crushed. As the spray bar 5 continuously sprays water mist onto the crushing roller 403, it reduces the frictional heat during the crushing of the shells and also prevents the wet shells from splashing when crushed again. Finally, the unshelled almonds are cut again by the pressure roller 404. The opening mechanism effectively prevents almonds from remaining unshelled. After passing through the shelling mechanism 4, the almonds are conveyed into the drying chamber 7. The drying chamber 7 is heated to a high temperature due to the heating wire 701. The rotation of the rolling roller 403 drives the rotation of the gear set 405, which in turn drives the crank connecting rod 406 and the push rod 407 to move back and forth within the limit guide sleeve 702. This causes the swing plate 409 to swing, so that the drying chamber 7 contains not only heat but also hot air, which accelerates the drying of the almonds after watering and shelling.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
