LPG spray dryer for instant coffee
Product Introduction
Equipped with centrifugal atomizer, centrifugal spray drying tower
is one of the most widely used dryer in industrial production. By adding material liquid to the high speed rotating spray tray , liquid is flung into droplets
after drying in the drying chamber subjected to centrifugal force.
Working Principle
Feed pump sends pump water reducing agent solution to the high speed centrifugal
atomizer in the middle of the drying tower by using high speed rotating centrifugal force, the
material liquid to spray
fine droplets. Approved by the heat source of hot air, heating points after reasonable
ventilation, win into the drying tower. Droplets are fully mixed with hot air drying tower, for heat and mass transfer in
quickly,in a very short time be dry powder products,grain size larger products from dry bottom,
smaller particle size productwith hot air into the cyclone dust collector,separation of products by the
discharge valve discharge, via water containing a small amount of
dust exhaust dust after emptying.
Performance characteristics
1. The one-time continuous drying can be realized.
2. The spray drying of fog moment and droplets particle diameter
can be adjusted slightly.
3. Reasonable air distribution.
4. The product particles are more fine than that by pressure type spray.
5. The production process is simple and operates conveniently.
