[0024] Please refer to Figures 1-4 , by setting buffer tank 4 on the outer side of drying machine main body 1, then setting annular cooling plate 5 and auxiliary assembly 2 in buffer tank 4, the heat in drying machine main body 1 is used to heat the air between drying machine main body 1 and annular cooling plate 5, the heated air enters hot air pipe 3 through communication pipe 14, so that the heat returns to drying machine main body 1, reduces heat loss, and auxiliary assembly 2 is located on the outer side of annular cooling plate 5, which can take away the excessive heat generated by the side wall of drying machine main body 1, avoiding the pasting of traditional Chinese medicine extract.

[0025] Among them, such as Figure 2As shown, the auxiliary assembly 2 includes a cold water pipe 9, one end of which is fixed to the outside of the bottom of the buffer tank 4, the other end is fixed to the outside of the top of the buffer tank 4, the middle of the cold water pipe 9 is spirally arranged in the buffer tank 4, the buffer tank 4 is uniformly provided with a partition plate 10, the middle of the cold water pipe 9 is fixed with the partition plate 10, which is used to improve the heat dissipation efficiency of the inside of the buffer tank 4, improve the heat dissipation effect of the annular cooling plate 5, and then quickly cool the side wall of the drying machine body, one end of the partition plate 10 is provided with an opening 11, the openings 11 of the adjacent two partition plates 10 are located at the top and bottom of the inside of the buffer tank 4 respectively, the cold air entering the buffer tank 4 through the air inlet moves up and down in the buffer tank 4 through the opening 11 and the partition plate 10, which improves the retention time of the cold air in the buffer tank 4.

[0026] In addition, as Figure 2 shown, the bottom of the annular cooling plate 5 is fixed with a ring-shaped filter plate 12, which can filter impurities in the cold air, avoid impurities entering between the annular cooling plate 5 and the drying machine body with the cold air, and then avoid impurities entering the hot air pipe 3 through the communication pipe 14, avoid polluting the products in the drying machine.
