[0002] EGCG refers to epigallocatechin gallate, which is the main component of tea polyphenols. It has antibacterial, anti-angiogenic, and anti-tumor effects. EGCG crystals refer to EGCG in crystalline form. EGCG crystals can be roughly divided into two categories of uses. In the food industry, it can be used as an antioxidant, antibacterial, preservative, deodorant, etc. In daily chemical products, it can be used as a special-function preservative and skin care agent. When processing EGCG crystals, the EGCG crystals need to be dried at low temperature to prevent the presence of moisture in the EGCG crystals.

[0003] The patent with the patent authorization announcement number CN220187246U discloses a drying crystallization device, including a drying box, a limit groove and a fixed ring. A sealing cover is movably installed on the top of the drying box, a support column is fixedly installed on the outside of the drying box, and a limit plate is fixedly installed on the front end of the sealing cover. Although the above patent can use the fixed ring, ventilation plate and electric heating wire to dry the material on the isolation plate with hot air, the device still has shortcomings in actual use.

[0025] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0026] Example 1: A low temperature drying device for EGCG crystals, see Figure 1-Figure 8 As shown, it includes a box body 1, a front cover plate 101, a rear cover plate 102, a lower hopper 2, a machine wheel 4, a conveyor belt 3, a hot air blower 6, a rotating fan 8, a ventilation plate 9, a control module 13, a visual window 14 and a discharge hopper 15. The interior of the box body 1 is divided into two cavities. The front part of the box body 1 is connected to the front cover plate 101 by bolts, and the rear part of the box body 1 is connected to the rear cover plate 102 by bolts. The upper part of the box body 1 is connected to the lower hopper 2 for lowering EGCG crystals by bolts. At least five machine wheels 4 are connected to the inside of the box body 1 by bolts. A conveyor belt 3 for conveying EGCG crystals is rotatably connected between two machine wheels 4 on the same horizontal line. A low-density air permeable net is provided on the conveyor belt 3. The lower part of the box body 1 is connected to the left and right by bolts. The hot air blower 6 is distributed, and the hot air blower 6 is provided with air outlets 7 evenly distributed at intervals. The lower part of the box body 1 is rotatably connected to a rotating fan 8. The upper part of the box body 1 is connected to ventilation plates 9 distributed on the left and right by bolts. The right part of the front cover 101 is connected to a control module 13 by bolts. The control module 13 is electrically connected to the motor 201, the hot air blower 6 and the machine wheel 4. The upper part of the front cover 101 is embedded with a visual window 14 for viewing the situation. The right part of the box body 1 is connected to a discharge hopper 15 by bolts. The discharge hopper 15 is located at the lower right side of the conveyor belt 3 on the lower side. By starting the machine wheel 4, the machine wheel 4 rotates to rotate the conveyor belt 3 to transport the EGCG crystals. Then the hot air blower 6 is started to inhale air, and the air is discharged through the air outlet 7 to dry the EGCG crystals on the conveyor belt 3.

[0027] See also Figure 3 As shown, it also includes a motor 201 and a stirring plate 202. The front part of the lower hopper 2 is connected to the motor 201 by bolts, and the stirring plate 202 for stirring the EGCG crystals is connected to the output shaft of the motor 201 by welding. The stirring plate 202 is driven by the output shaft of the motor 201 to rotate and stir the EGCG crystals.

[0028] See also Figure 1 , Figure 4 and Figure 5 As shown, it also includes an inclined plate 5 and a sponge block 501. The inside of the box body 1 is connected with an inclined plate 5 for guiding EGCG crystals by bolts. The conveyor belt 3 is in contact with the inclined plate 5. The EGCG crystals are guided to the conveyor belt 3 through the inclined plate 5. The lower part of the inclined plate 5 is connected with a sponge block 501 for cleaning, and the sponge block 501 is in contact with the conveyor belt 3.

[0029] First, the staff pours the EGCG crystals into the lower hopper 2, and then starts the motor 201 through the control module 13. The output shaft of the motor 201 rotates to drive the stirring plate 202 to rotate and stir the EGCG crystals, and the EGCG crystals in the lower hopper 2 are slowly lowered into the box body 1. The lowered EGCG crystals fall along the inclined plate 5 to the uppermost conveyor belt 3, and then the hot air blower 6 is started through the control module 13 to make it run to draw in the outside air, and the rotating fan 8 rotates to make the air flow quickly into the hot air blower 6. After the drawn air is heated, it is discharged into the box body 1 through the air outlet 7 and surges upward, thereby drying the EGCG crystals on the conveyor belt 3, and then the machine wheel 4 is started through the control module 13. The two machine wheels 4 on the same horizontal line The conveyor belt 3 is coordinated to rotate. The uppermost conveyor belt 3 rotates to convey the EGCG crystals to the right, causing the EGCG crystals to fall onto the middle conveyor belt 3. The middle conveyor belt 3 rotates to convey the EGCG crystals to the left, causing the EGCG crystals to fall onto the lower conveyor belt 3. The lower conveyor belt 3 rotates to convey the EGCG crystals to the right, causing the EGCG crystals to fall onto the discharging hopper 15 for discharging. The staff collects the EGCG crystals, thereby achieving the effect of conveying the EGCG crystals while drying, which is convenient for batch drying of EGCG crystals. When the conveyor belt 3 rotates, it continues to contact the sponge block 501. The sponge block 501 brushes off the EGCG crystals on the surface of the conveyor belt 3 to avoid excessive EGCG crystals remaining on the conveyor belt 3.

[0030] Example 2: Based on Example 1, refer to Figure 7 As shown, it also includes a condensation plate 10, a water storage frame 11 and a water outlet pipe 12. The condensation plate 10 is connected to the upper part of the box body 1 by means of bolts. The condensation plate 10 is obliquely arranged in the box body 1. The inside of the box body 1 is connected to a water storage frame 11 for collecting condensed water by means of bolts. The water storage frame 11 is located below the condensation plate 10. The water storage frame 11 is connected and communicated with a water outlet pipe 12, and the water outlet pipe 12 runs through the box body 1.

[0031] When the EGCG crystals are dried, the moisture in the EGCG crystals will evaporate to form water vapor, which will float up and contact the condensation plate 10 to form condensed water. The condensed water will flow along the condensation plate 10 into the water storage frame 11 and then be discharged through the water outlet pipe 12, thereby achieving the effect of removing water vapor and preventing the humidity inside the box 1 from being too high to affect the drying quality.
