Flash dryer

Introduction:

Flash drying is a drying method to completely fluidize solids. The drying host of flash dryer has the mechanical, airflow dispersion, and columnar adjustment functions for drying materials. The paste and cake like materials with high moisture content are added to the drying host and mixed with the heated hot medium. Under the action of hot air and mechanical dispersion, the materials form a double swirl granular fluidization state, which instantly completes the heat and mass exchange, The dried materials enter the collector to obtain powdery products.

characteristic:

1. The whole system is closed without cross contamination, and the recovery rate is above 99%.

2. Instantaneous drying, drying time 1~3 seconds, material retention time less than 10 seconds, particle size distribution is uniform, product is not overheated, and liquidity is good.

3. Hot air stove, steam and electricity are used as heat sources. Coal, gas and liquid are used as fuel, and the combustion mode is direct or indirect. The temperature of hot air is 80~1000 ℃.

4. High heat utilization rate, strong evaporation capacity, heat consumption of 900~1500Kcal/kgH2O, and evaporation capacity of series products of 40~4000kgH2O/h (single set).

5. It is suitable for drying filter cake and paste materials with high moisture content. The moisture content of the materials can reach more than 90, and the final moisture content is below 0.5%.

6. Small floor area, simple and convenient operation, automatic control can be realized according to different requirements of users, and the comprehensive operation cost of equipment is low.
