Description
Technical Field
[0001] This utility model relates to the field of airflow drying technology, and in particular to a control device for stable airflow drying quality. Background Technology
[0002] Airflow drying technology, as a highly efficient and continuous material drying method, is widely used in food processing (such as grains and fruit and vegetable flakes), chemical production (such as plastic granules and catalysts), and pharmaceutical manufacturing (such as traditional Chinese medicine decoction pieces and raw materials). Its core principle is to ensure full contact between high-temperature airflow (50-300℃) and wet materials, utilizing convective heat transfer to achieve rapid evaporation of moisture (drying efficiency can reach 3-5 times that of traditional drying ovens). Finally, the dried materials are conveyed to subsequent processes (such as packaging and screening) through a feeding device.
[0003] The smoothness of the material feeding process directly affects the stability of the drying quality. If blockage occurs, it will cause the material to remain in the drying chamber for too long (leading to localized overheating and deterioration) or the flow rate to drop sharply (undried material will mix into the finished product). If the flow rate fluctuates due to blockage, it will result in uneven drying of the material.
[0004] Therefore, it is necessary to provide a new control device for airflow drying with stable quality to solve the above-mentioned technical problems. Utility Model Content

[0027] The working principle of this utility model is as follows: The induced draft fan 102, blower 103, heater 1, cyclone dust collector 107, cyclone dust collector 2 108, and feeder 105 are started simultaneously by an external power source. The induced draft fan 102 generates air and sends it into the cyclone dust collector 107 through the heating pipe 101. After the cyclone dust collector 107 performs primary dust removal, the air is sent into the cyclone dust collector 2 108 through the air duct for secondary dust removal. After secondary dust removal by the cyclone dust collector 2 108, the air is sent into the heater 1 through the three-way heating pipe 2 109 for heating.

The material is then fed into the feeder 2 and then sent into the three-way heating pipe 2 109 by the feeder 105 for drying.
[0028] Material enters the discharge box 7 through two feeding frame plates 201. When accumulation occurs, the stirring motor 3 is activated, driving the stirring motor shaft 303 to rotate the protective shell 301 in a circular motion. The protective shell 301 drives several stirring blade connecting rods 305 to rotate in a circular motion, which in turn drives several transmission gears 304 to rotate synchronously. Subsequently, the transmission gears 304 rotate around the fixed gear 601 in a circular motion. Then, the stirring blade connecting rods 305 drive several stirring blade rods 302 to stir the accumulated material and assist in the discharge. The discharge motor is then activated again. The machine 402 drives the feeding motor shaft 405 to drive the crank 406 to rotate in a circular motion. The crank 406 drives the slider 408 to rotate through the crank connecting rod 407. When the slider 408 moves, it slides up and down in the slide plate 404. Then the slider 408 pushes the slide plate 404 to move back and forth in a reciprocating lateral motion. The slide plate 404 pushes the feeding swaying plate 5 to move back and forth in the same way through the connecting plate 403. Then the feeding swaying plate 5 pushes the material accumulated at the bottom to make it flow and facilitate feeding. Through the above operation, the material can be prevented from blocking, the material can be heated evenly, and the material loss rate can be reduced.
