[0002] In D-ribose production, the crystalline wet product needs further drying. During the drying process, the crystals tend to clump together, affecting moisture evaporation and reducing drying quality. To overcome this technical problem, existing technologies, such as the patent with publication number CN216308501U, "A Drying Device for D-ribose Processing with Anti-Clumping," have the following drawbacks: First, the heating temperature of normal D-ribose crystals should be controlled between 40℃ and 70℃, and the heating temperature should not be too high. This patent uses hot air and electric heating wires, which are difficult to control and can easily cause localized high temperatures, leading to product deterioration and affecting product quality. Second, the reciprocating spinning method to break up crystal clumps is ineffective, and large clumps still remain. The moisture in these clumps is difficult to release, affecting drying quality. Third, the method of opening doors to access materials involves a lot of manual operation, which is time-consuming and labor-intensive, resulting in intermittent production and low efficiency.

Detailed Implementation

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of this utility model, and are not intended to limit the protection scope of this utility model.

[0020] Example: Please refer to Figure 1-5 This utility model provides the following technical solution: a D-ribose wet product drying device, comprising a tank 1 with an inlet 11 and an outlet 12 at its upper and lower ends respectively; a first valve 13 and a second valve 14 are respectively provided on the inlet 11 and the outlet 12; an air outlet 15 is also provided at the top of the tank 1, and a third valve 16 is provided on the air outlet 15, the end of which is connected to a vacuum pump 2; the tank 1 is provided with multiple sieving units spaced vertically; each sieving unit includes a hollow sieve plate 3 and a rolling roller 4 lying horizontally on the upper surface of the hollow sieve plate 3; the hollow sieve plate 3 includes a top plate 31 and a bottom plate 32 that are sealed and fixed to the side wall of the tank 1, for forming a cavity 33 inside the hollow sieve plate 3; the tank 1 A water inlet pipe 35 and a water outlet pipe 36, connecting the cavity 33, are fixedly installed on the side wall for supplying flowing hot water into the cavity 33. A densely distributed screen tube 34 is provided on the hollow screen plate 3. The upper and lower ends of the screen tube 34 penetrate the top plate 31 and the bottom plate 32 and are sealed and fixedly connected to the top plate 31 and the bottom plate 32. A shaft hole 37 is provided in the center of the hollow screen plate 3. The main shaft 5 passes through the shaft holes 37 of all the screening units, and its upper end is connected to a motor 51 fixed to the top of the tank body 1. The crushing roller 4 includes a roller sleeve 42 fitted outside the first horizontal shaft 41. One end of the first horizontal shaft 41 is fixedly connected to the main shaft 5, and when the main shaft 5 rotates, it drives the roller sleeve 42 to crush the upper surface of the hollow screen plate 3. The first valve 13, the second valve 14, and the third valve 16 are all electrically controlled valves, which are convenient to operate and save manpower.

[0021] In operation, wet material enters tank 1 through inlet 11. First valve 13 and second valve 14 are then closed, while third valve 16 is opened. Air pump 2 depressurizes the air inside tank 1. Simultaneously, hot water is introduced into the hollow screen plate 3 to heat the wet material on it. This simultaneous heating and depressurization fully releases moisture from the material, achieving a drying effect. Then, motor 51 is started, and main shaft 5 drives roller sleeve 42 to crush the wet material, breaking up clumps into small particles. These particles fall through screen tube 34 and enter the next screening unit for further crushing. Finally, the crushed and dried material enters the bottom of tank 1, concentrating in the conical area at the bottom. Then, third valve 16 and air pump 2 are closed, and second valve 14 is opened to discharge the dried material. Simultaneously, first valve 13 can be opened to input the next batch of wet material. After feeding is complete, first valve 13 is closed, and then third valve 16 and air pump 2 are opened again. Therefore, the opening of the first valve 13 does not depend on whether the second valve 14 is closed, making the drying process a continuous and uninterrupted production method. The inlet 11 and outlet 12 can be connected to a continuous production pipeline system, serving as a drying module within that system, resulting in high efficiency. Preferably, the diameter of the screen tubes 34 of the multiple screening units decreases sequentially from top to bottom, allowing for gradual crushing and refinement of the material.

[0022] As can be seen, this device has the advantages of warm water heating, suitable temperature and easy control, and step-by-step drying and crushing to prevent agglomeration. It has a good crushing effect, high material drying quality, uninterrupted feeding and discharging, less manual operation and high production efficiency.

[0023] Preferably, the inlet pipes 35 and outlet pipes 36 of two adjacent screening units are connected by a connecting pipe 38 to connect multiple hollow screen plates 3 in series. This allows for sufficient heat exchange of the hot water before discharge, reducing waste and energy consumption. The inlet pipe 35 at the bottom is used for water intake, and the outlet pipe 36 at the top is used for water outlet. This bottom-up water supply ensures that each hollow screen plate 3 is fully filled, avoiding air blockage and resulting in more uniform heating.

[0024] When the roller 4 rotates, it is subjected to the reaction force of the material and tends to lift upward. In order to increase the rolling pressure, the end of the first horizontal shaft 41 is inserted into the groove 17 preset on the side wall of the tank body 1 to prevent the roller 4 from rising, increase the downward pressure, and improve the rolling effect.

[0025] To reduce the risk of clogging of the screen tube 34, each screening unit has a second horizontal shaft 6 below the hollow screen plate 3. One end of the second horizontal shaft 6 is rotatably inserted into a sleeve 52 fixed to the side wall of the main shaft 5, and the other end is fixed to a gear 61. The gear 61 meshes with a gear ring 62 fixed to the side wall of the tank 1, and is used to drive the second horizontal shaft 6 to rotate when the main shaft 5 rotates. Multiple swing ropes 63 are fixed to the second horizontal shaft 6, and the ends of the swing ropes 63 are connected to swing balls 64 for impacting the hollow screen plate 3 above. Therefore, when the main shaft 5 rotates, the continuously swinging swing balls 64 will impact the bottom of the hollow screen plate 3, and the vibration will cause the material in the screen tube 34 to fall, reducing the risk of clogging.

[0026] To prevent lateral movement of gear 61 and the second horizontal shaft 6, and to ensure that gear 61 is always positioned above gear ring 62, a rotatable ball 65 is provided on the outer end face of gear 61, the ball 65 abutting against the inner wall of the tank body 1. The ball 65 and the sleeve 52 form a pair of limiting components to ensure that the positions of gear 61 and gear ring 62 correspond.

[0027] To improve the mixing effect and promote the upward movement of material from the bottom to the top, thereby increasing drying efficiency, each screening unit has a third horizontal shaft 7 above the rolling roller 4. One end of the third horizontal shaft 7 is fixedly connected to the main shaft 5, and the other end is fixedly connected to the stirring blade 71. The stirring by the stirring blade 71 can improve drying efficiency and prevent agglomeration.

[0028] The advantages of this embodiment are that it uses warm water heating, which provides a suitable and easily controllable temperature; multiple screening units are spaced apart, which dry and crush the material step by step to prevent clumping, resulting in good crushing effect, high material drying quality, uninterrupted feeding and discharging, less manual operation, and high production efficiency.

[0029] The parts of this utility model not described in detail are prior art; for those skilled in the art, the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. The scope of this utility model is defined by the appended claims and their equivalents.
