[0024] During operation, due to the poor heating effect of the existing roasting tower furnace, the material in the furnace body cannot be turned over, resulting in uneven heating and incomplete drying, which affects the quality of the finished product. In this solution, the sealing plug 9 is rotated and sealed in the bottom opening of the inner funnel 2, and the catalytic liquid is poured into the liquid storage tank 18. Then the raw material is put into the furnace body 1 from the feed pipe 28. After the raw material enters the furnace body 1, it will fall on the guide plate 11 and disperse in the inner funnel 2 under the guidance of the guide plate 11. Then, the heating controller 15 controls the No. 2 heating plate 14 and the No. 1 heating plate 12 to heat. When the No. 2 heating plate 14 is heated, it will heat the wall of the furnace body 1, and when the No. 1 heating plate 12 is heated, it will heat the guide plate 11. The motor 21 is controlled to operate, and the motor 2 1 will drive the rotating shaft 7 to rotate, and the rotating shaft 7 will drive the auger 8 to rotate in the hollow tube 6, and the auger 8 will roll the raw materials that fall on the lower part of the inner funnel 2 and are located on the sealing plug 9 into the hollow tube 6 when it rotates, and the auger 8 cooperates with the hollow tube 6 to transport the raw materials at the lower part of the inner funnel 2 to the upper end of the hollow tube 6. When the raw materials are transported to the upper end of the hollow tube 6, they will be discharged from the upper opening of the hollow tube 6 and fall on the guide plate 11. Then, under the heating of the guide plate 11 by the first heating plate 12, the raw materials that fall on the guide plate 11 are heated and dried, and under the guidance of the guide plate 11, the raw materials on the guide plate 11 will be dispersed and guided to contact the inner wall of the furnace body 1, and the raw materials will be dried again under the heating action of the second heating plate 14 on the furnace body 1.

After drying, the heating temperature of the No. 1 heating plate 12 and the No. 2 heating plate 14 will be increased to carry out the roasting process, and then the raw materials will be turned over during the drying and roasting process, and the No. 2 solenoid valve 24 will be opened during the drying and roasting process. The exhaust gas generated during the drying and roasting will enter the exhaust gas treatment component 23 through the smoke exhaust pipe 22, thereby avoiding exhaust gas leakage. After the drying and roasting is completed, the infusion pump 19 is controlled to operate. When the infusion pump 19 is running, the catalytic liquid in the liquid storage tank 18 will be transported to the spray head 20, and the catalytic liquid will be evenly discharged from the spray head 20. The catalytic liquid is sprayed into the furnace body 1. After being sprayed into the furnace body 1, it will flow downward and gather at the bottom of the inner funnel 2, and will penetrate into the liquid storage bin 10, thereby soaking the raw materials in the inner funnel 2. After soaking, the No. 1 solenoid valve 17 is opened. After the No. 1 solenoid valve 17 is opened, the catalytic liquid in the liquid storage bin 10 will flow back into the liquid storage tank 18. At this time, under the operation of the auger 8, the soaked raw materials will be transported to the upper end of the hollow tube 6 again. During the transportation process, the catalytic liquid in the raw materials will penetrate out of the hollow tube 6 through the through groove 25 and remain in the lower part of the inner funnel 2. The catalytic liquid in the inner funnel 2 will also penetrate into the liquid storage bin 10 through the No. 1 through hole 3, thereby draining the catalytic liquid in the inner funnel 2. After draining, close the No. 1 solenoid valve 17 to proceed to the next circulation process.After the processing is completed, the sealing plug 9 can be unscrewed from the lower end of the inner funnel 2 to discharge the materials in the inner funnel 2, which can achieve the effect of improving the drying and roasting effect. It can be turned over during the drying and roasting process to improve the uniformity of the drying and roasting of the raw materials and effectively ensure the product quality.

[0025] Working principle, by rotating the sealing plug 9 and sealing it in the opening at the bottom end of the inner funnel 2, the catalytic liquid is poured into the liquid storage tank 18, and then the raw materials are put into the furnace body 1 from the feeding pipe 28. After the raw materials enter the furnace body 1, they will fall on the guide plate 11, and under the guidance of the guide plate 11, they will be dispersed and fall into the inner funnel 2. Then, the heating controller 15 controls the No. 2 heating plate 14 and the No. 1 heating plate 12 to heat. When the No. 2 heating plate 14 is heated, it will heat the wall of the furnace body 1, and when the No. 1 heating plate 12 is heated, it will heat the guide plate 11. Cooperate with the control motor 21 to operate, the motor 21 will drive the rotating shaft 7 to rotate when it operates, and when the rotating shaft 7 rotates, it will drive the auger 8 to rotate in the hollow tube 6, and when the auger 8 rotates, it will fall on the lower part of the inner funnel 2 and be located in the sealing The raw materials on the sealing plug 9 are rolled into the hollow tube 6, and the auger 8 cooperates with the hollow tube 6 to transport the raw materials at the lower part of the inner funnel 2 to the upper end of the hollow tube 6. When the raw materials are transported to the upper end of the hollow tube 6, they will be discharged from the upper opening of the hollow tube 6 and fall on the guide plate 11. Then, under the heating of the guide plate 11 by the No. 1 heating plate 12, the raw materials falling on the guide plate 11 are heated and dried, and under the guidance of the guide plate 11, the raw materials on the guide plate 11 will be dispersed and guided to contact the inner wall of the furnace body 1. Under the heating action of the No. 2 heating plate 14 on the furnace body 1, the raw materials will be dried again. The dried raw materials will fall on the bottom of the inner funnel 2 again and be located above the sealing plug 9. Under the continuous transportation of the auger 8, the raw materials falling in the bottom end of the inner funnel 2 will be continuously transported upward, and During the transportation process, the raw materials are dispersed and dried, and after drying, the heating temperature of the No. 1 heating plate 12 and the No. 2 heating plate 14 is increased to carry out the roasting process, and then the raw materials are turned over during the drying and roasting process, and the No. 2 solenoid valve 24 is opened during the drying and roasting process. The exhaust gas generated during the drying and roasting will enter the exhaust gas treatment component 23 through the smoke exhaust pipe 22, thereby avoiding exhaust gas leakage. After the drying and roasting is completed, the infusion pump 19 is controlled to operate. When the infusion pump 19 is running, the catalytic liquid in the liquid storage tank 18 will be transported to the spray head 20, and evenly sprayed into the furnace body 1 from the spray head 20. After the catalytic liquid is sprayed into the furnace body 1, it will flow downward and gather at the bottom of the inner funnel 2, and will penetrate into the liquid storage tank 10, thereby soaking the raw materials in the inner funnel 2. After the soaking is completed, open the No. 1 solenoid valve 17. After the No. 1 solenoid valve 17 is opened, the catalytic liquid in the liquid storage bin 10 will flow back into the liquid storage tank 18. At this time, the soaked raw materials will be transported to the upper end of the hollow tube 6 again under the operation of the auger 8. During the transportation process, the catalytic liquid in the raw materials will penetrate out of the hollow tube 6 through the through groove 25 and remain in the lower part of the inner funnel 2, and the catalytic liquid in the inner funnel 2 will also penetrate into the liquid storage bin 10 through the No. 1 through hole 3, and then the catalytic liquid in the inner funnel 2 will be emptied. After emptying, close the No. 1 solenoid valve 17 to carry out the next circulation process.
