Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a high-efficiency and energy-saving drying device for glutinous rice. Background Technology

[0002] Silky rice, a premium rice variety favored by consumers, holds an important position in the market due to its long, slender grains, translucent appearance, and soft, sweet taste. However, drying is a crucial step in the process from its initial state after harvesting to meeting storage, processing, and sales standards. Traditional silky rice drying methods have many drawbacks and cannot meet the current dual demands of efficient production and energy conservation.

[0003] In the past, most drying equipment used a single heating method or relied solely on hot air blowing. This method resulted in uneven heat distribution, with rice near the heat source being over-dried and losing nutrients, while rice further away was under-dried. This led to inconsistent quality of the dried rice, with a high rate of broken rice, severely impacting economic efficiency. Moreover, traditional equipment often lacked precise feeding control mechanisms. Large quantities of rice were poured into the drying area at once, piling up too thickly. The rice inside could not fully contact the heat, further exacerbating the uneven drying problem, significantly extending the drying cycle, and consuming a large amount of electricity and time. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency and energy-saving rice drying device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution, which includes a U-shaped mounting frame, with support legs symmetrically arranged at the bottom of both sides of the U-shaped mounting frame, a heating and drying channel arranged inside the U-shaped mounting frame, and rotating shafts symmetrically arranged on the outer walls of both sides of the heating and drying channel. The rotating shafts are movably mounted inside the U-shaped mounting frame through bearing seats, and drying components are symmetrically arranged at the top and bottom of the heating and drying channel, one of which contains a slow feeding component.

[0006] As a preferred embodiment of this utility model, a first flange is provided at both the top and bottom of the heating and drying channel, a heating wire is wound around the wall of the heating and drying channel, and an insulation cotton layer is provided on the outside of the heating wire, which is disposed in the wall of the heating and drying channel.

[0007] In a preferred embodiment of this invention, the drying assembly includes a feeding hopper. The top of the feeding hopper is movably fitted with an opening / closing cover via several hinges. A pair of mounting blocks are located at the front end of the opening / closing cover. A rotating component is movably mounted between the two mounting blocks, and a screw is located at the bottom of the rotating component. A pair of positioning blocks are located on the outer wall of the feeding hopper, with the two positioning blocks positioned below the mounting blocks. The screw is located between the two positioning blocks, and a nut is threaded onto the screw, abutting against the bottom of the positioning blocks. L-shaped tubes are symmetrically arranged on both outer walls of the feeding hopper. Heating wires are installed inside the L-shaped tubes, and a fan is installed at the end of each L-shaped tube furthest from the feeding hopper. Several heating strips are installed on the inner wall of the feeding hopper. A baffle is installed at the end of each L-shaped tube inside the feeding hopper. A power supply module is also installed on the outer wall of the feeding hopper, and the heating wires and heating strips are electrically connected to the power supply module.

[0008] As a preferred embodiment of this utility model, the bottom of the discharge hopper is provided with a second flange, and the second flange and the first flange are fixed together by a group of bolts.

[0009] As a preferred embodiment of this utility model, the slow feeding assembly includes a forward and reverse motor disposed at the top of the feeding hopper, a transmission rod disposed on the transmission end of the forward and reverse motor, the bottom end of the transmission rod passing through the heating and drying channel and located inside another feeding hopper, and a pushing spiral blade disposed on the transmission rod.

[0010] As a preferred embodiment of this utility model, the bottom of the U-shaped mounting bracket is provided with a pair of telescopic cylinders, and the top of the discharge hopper is provided with a fixing block. The fixing block is provided with a pair of positioning holes, and the two positioning holes correspond to the telescopic rods of the two telescopic cylinders respectively.

[0011] As a preferred embodiment of this invention, the heating wire is electrically connected to one of the power supply modules.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] 1. This utility model incorporates several heating strips inside the feeding hopper of the drying assembly, allowing for direct heating and drying of the rice from the inside. Simultaneously, heating wires are installed in the L-shaped pipes on both outer walls. The fan guides air through the heating wires, which process it into hot air before it is introduced into the feeding hopper for further heating and drying. In addition, heating wires wound around the wall of the heating and drying channel also provide heat for drying. This multi-source heating method heats the rice from different angles and levels, significantly improving drying efficiency and enabling the rice to be dried to the ideal state in a short time, thus greatly saving energy.

[0014] 2. This utility model uses a slow feeding component to quantitatively and slowly convey the jasmine rice into the heating and drying channel, allowing the jasmine rice to fully receive heat as it passes through the channel. This avoids the problem of rice accumulating in the middle and failing to dry, ensuring uniform drying and guaranteeing that each grain of jasmine rice receives proper drying treatment, thus improving the drying quality.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0026] like Figures 1-9 As shown, this utility model proposes a high-efficiency and energy-saving glutinous rice drying device. This utility model includes a U-shaped mounting frame 1, with support legs 10 welded symmetrically to the bottom of both sides of the U-shaped mounting frame 1. A heating and drying channel 3 is provided inside the U-shaped mounting frame 1. Rotating shafts 31 are symmetrically arranged on the outer walls of both sides of this channel. The rotating shafts 31 are mounted on the U-shaped mounting frame 1 through bearing seats 32. The heating and drying channel 3 can be flexibly rotated around the rotating shafts 31 as the axis.

[0027] The heating and drying channel 3 is provided with a first flange 30 at the top and bottom. A heating wire 33 is spirally wound inside the channel wall. The heating wire 33 is covered with a heat insulation cotton layer 34. The heating and drying channel 3 is provided with a drying component 4 at the top and bottom.

[0028] The drying assembly 4 includes a feeding hopper 40. The top of the feeding hopper 40 is connected to an opening and closing cover 43 by several hinges 42. A pair of mounting blocks 44 are welded to the front end of the opening and closing cover 43. A rotating part 45 is movably arranged in the middle. A screw 46 is provided at the bottom of the rotating part 45. A pair of positioning blocks 47 are provided on the outer wall of the feeding hopper 40, located below the mounting blocks 44. When the rotating part 45 rotates as needed, the screw 46 will fall between the two positioning blocks 47. The nut 48 is tightened and pressed tightly against the bottom of the positioning block 47. The opening and closing cover 43 is firmly locked by the friction of the threads and the mechanical pressure.

[0029] L-shaped pipes 49 are symmetrically installed on the outer walls of both sides of the feeding hopper 40. Heating wires 410 are installed inside the pipes. The end of each L-shaped pipe 49 away from the feeding hopper 40 is firmly connected to a fan 411. The fan 411 forcefully blows air into the L-shaped pipes 49, which is heated by the heating wires 410. The airflow is evenly distributed by the baffles 416 at the pipe ends and evenly sprayed onto the rice material, while preventing the rice material from falling into the L-shaped air pipes. Several heating strips 412 are distributed at intervals on the inner wall of the feeding hopper 40, conforming to the curvature of the hopper wall. The heating strips 412 and the heating wires 412 are reliably electrically connected to the power supply module 413 on the outer wall. The second flange 41 at the bottom of the feeding hopper 40 is fixed to the first flange 30 of the heating and drying channel 3 by several bolt groups 6.

[0030] The slow feeding component 5 includes a forward and reverse motor 50 set at the top of the feeding hopper 40. Its transmission end is closely connected to the transmission rod 51, passes through the heating and drying channel 3, and goes deep into the interior of another feeding hopper 40. The transmission rod 51 is equipped with a pushing spiral blade 52 to prevent the feeding from being too fast, causing uneven drying or blockage.

[0031] The bottom of the U-shaped mounting bracket 1 is equipped with a pair of telescopic rods, and the top of the material discharge bucket 40 is equipped with a fixing block 414, which has a pair of positioning holes 415 with the diameter of the holes matching the telescopic rod of the telescopic cylinder 2.

[0032] Before use, carefully check the equipment status. After confirming that everything is correct, turn on the heating bars 412, heating wire 33 and heating wire 410 distributed in key positions of the equipment simultaneously for preheating. During this preheating process, align the positioning block 47 on the bottom drying component 4 with the two telescopic cylinders 2, adjust the angle, and ensure that the positioning hole 415 is absolutely perpendicular to the telescopic cylinder 2. Then start the two telescopic cylinders 2 until the telescopic rod of the telescopic cylinder 2 is accurately inserted into the positioning hole 415. At this time, the drying component 4 is firmly locked.

[0033] After the drying component 4 is fixed, the staff takes the appropriate tool and firmly unscrews the nut 48 on the opening and closing cover 43 of the upper drying component 4. The opening and closing cover 43 can then be opened. At this time, the rice to be processed is slowly and evenly poured into the upper feeding hopper 40, taking care to prevent spillage. After the rice is completely poured in, the rotating part 45 is manually rotated until the screw 46 is placed between the two positioning blocks 47. Then the nut 48 is screwed onto the screw 46 and gradually tightened until the nut 48 is firmly pressed against the two positioning blocks 47. This ensures that the opening and closing cover 43 is tightly closed, forming a closed drying space and preventing material leakage.

[0034] After the material is filled, the heating strip 412 inside the feeding hopper 40 heats up and releases heat to directly heat and dry the rice inside. At the same time, the fan 411 is turned on and the air is introduced into the L-shaped air duct. When the cold air passes through the heating wire 410, it is heated into hot air and introduced into the feeding hopper 40. Together with the heating strip 412, it further enhances the drying efficiency. Meanwhile, the slow feeding component 5 is started and the forward and reverse motor 50 runs smoothly, driving the transmission rod 51 to rotate at a uniform speed. With the close cooperation of the pushing spiral blade 52, the rice in the upper feeding hopper 40 is slowly conveyed downward in the heating and drying channel 3 in a uniform amount. The rice moves slowly in the heating and drying channel 3 and continues to undergo high-temperature drying treatment before being further dried until it finally falls into the drying component 4 below.

[0035] After the rice in the upper feeding hopper 40 has completely fallen into the lower one, the slow feeding component 5 can be turned off. Then, the telescopic rods of the two telescopic cylinders 2 can be smoothly retracted to release the fixed state of the drying component 4. The operator holds the lower drying component 4 with both hands and rotates it around the rotating shaft 31 to make the positions of the upper and lower drying components 4 interchange. After the position is changed, the telescopic cylinders 2 are quickly started again to repeat the previous fixing steps and accurately position it. Then, the forward and reverse motor 50 is reversed to reverse the material conveying direction and transport the rice in the upper feeding hopper 40 to the lower feeding hopper 40. This process is repeated until the ideal drying effect is achieved.

[0036] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
