Air Flow Dryer

  • High drying strength: the ability to evaporate water from 50kg/h-1500kg/h.
  • High degree of automation and good product quality: the drying time is extremely short (only 0.5-2 seconds), so automation can be realized, the product is not in contact with the outside world, the pollution is small, and the quality is good.
  • The heating method has greater adaptability: the user can choose steam, electricity, or hot blast stove heating according to the conditions of the region. At the same time, it can be selected according to the heat-resistant temperature (or hot air temperature) of the material: when the temperature is less than or equal to 150 °C, steam heating can be selected; When ≤200℃, electric heating (or steam heating, electric compensation or heat transfer oil heating) ≤300℃. Coal-fired hot blast stove; when ≤600℃, oil-fired hot blast stove.

Optimization

Griffin Technology has been continuously optimizing the airflow dryer.

The airflow dryer is mainly used in the drying of starch and the drying of some inorganic salt products, such as drying of sodium sulfate and sodium metabisulfite, which has always had its unique advantages.

In the feeding mechanism of the air dryer, We have designed a unique anti-arch device, which can ensure the smooth and smooth entry of the raw materials into the air stream dryer without the phenomenon of bridging.

In the main engine of the airflow dryer, a unique pulse link is designed. Some products have relatively high requirements for final moisture. In order to prolong the drying time in the airflow dryer, we have made a pulse expansion section, which will buffer the drying of the product. The speed makes more full contact with the hot air.

In the dust removal and collection process of the airflow dryer, considering a large amount of dust, we have made explosion venting devices in the bag filter and the host to achieve the purpose of safe production.
