Positive and negative pressure airflow drying system
Positive and negative pressure airflow drying system
Product details

Advanced technology, reasonable layout, excellent manufacturing, and good usage effect. By adopting unique tail gas waste heat recovery technology, the annual steam consumption is reduced by more than 20% compared to domestic peers.


  Product Introduction:
The airflow drying system uses high-speed hot air flow to suspend the dried material, and uses pulse tubes to change the diameter of the sub tube section and the airflow velocity to continuously roll the material to achieve the purpose of drying. Therefore, it has a high heat transfer coefficient and can continuously dry a large amount of material. The drying time is only about 3-5 seconds, and the temperature of the dried material does not exceed 60 ℃.

  Main features:
A By using the variable diameter of the pulse tube's branch section, the airflow velocity is constantly changed, resulting in a high heat transfer coefficient and the ability to continuously dry large amounts of materials.
B The drying time of the material is only about 3-5 seconds, and the temperature of the dried material does not exceed 60 ℃, so the drying speed is fast and the material quality is good.
C The entire device operates under negative pressure, with a clean and pollution-free working environment.
D The overall capacity and steam consumption are lower than other drying equipment, making it an energy-saving product.
E Simple structure, convenient operation, small footprint, and low investment.
