pharmaceutical spray drying nozzle jet spray dryer Spray dryer granular machine
Spray dryer is one of the most popular industrial drying method, it could dried the powder directly from liquid o paste shape material.
The working principle is: cold air is filtered through the filter, then enters the heater, is heated to a certain temperature, and then enters the air distributor at the top of the spray tower, and the hot air spirally flows to the bottom of the tower. The liquid is pumped to the centrifugal atomizer at the top of the tower body, and the liquid is torn into extremely small mist droplets. The liquid droplets and the hot air are in parallel contact, and the heat exchange is fully performed. The water content is rapidly vaporized and evaporated, and dried in a very short time as a finished product. The finished product is separated by a cyclone and discharged, and the exhaust steam is discharged by an induced draft fan.
Main Features
(1) Fast drying: liquid or wet raw material after atomization, significantly increased surface area, in the hot air flow, instantaneous evaporation can be 95% ~98% moisture, to complete the drying time only a few seconds, and especially suitable for drying of thermal sensitive material.
(2) Excellent drying effect: Finished products with good uniformity, fluidity and solubility, the product high purity, good quality.
(3) Production process is simple, convenient operation and control. For material which moisture content 40-60% (special material even moisture contents 90%) of the liquid to a dry powder products, dried without crushing and screening, and product purity. Product size, density and moisture can be adjusted( within a certain range) by changing the operating conditions.
