LPG-5 Mini Spray Dryer is a special equipment and is suitable for drying emulsion, suspending liquid, liquor and so on. Particularly it has unique advantage for drying polymers and resins; dyestuff and pigment; ceramics, glass; derust agent; pesticide; carbohydrate, dairy products; detergent and surfactant; fertilizer, organic compound, inorganic compound and so on
Working Principle :
Air is turned into hot air through air filter and heater into hot air distributor at the top of dry chamber and then enters into dry chamber spirally and evenly, At the sametime liquid of raw material is sent to centrifugally tomizer at the top of dry chamber pumped by pump through filter, In which liquid of raw material atomizes ting droplets. Air and liquid of raw material flows and contacts each other fully. The moisture vaporizes rapidly. Liquid of raw material is dried into finished product in a short time. Tile finished product is discharged through cyclone separator at the bottom of drier. The wasted air is exhausted through fan.
Features:
Its dry speed is very quick. In general, it needs 5~15 seconds. It has feature of momentary dry.
Because raw material can be dried momentarily. Especially, it is suitable for drying thermal sensitive raw materials. It can maintain color, smell and smell of raw material.
Its operation is stable and simple. Its regulation and control is very convenient. It is easy to realize continuous operation.
The distribution, fluidity and solubility of product are good.
