Niro Type SD-200-R Sray dryer

622 Kgs/hr Niro Spray Drying Plant, Type SD-200-R, commissioned 1996/1997, by Niro A/s. Plant Characteristics: Atomization is through a rotary atomizer F-35, means of heating chamber direct gas-fired heater, Vibro Fluidizer steam-heated air heater, product recovery - cyclones and bag filter, product discharge - rotary valves. Operational data: amount of feed 608kg/h, product 601kg/h, water evaporative capacity 622kg/h, volatiles 7kg/h, capacity 1230kg/h, total 608kg/h, air inlet temperature chamber 145degC, Vibro Fluidizer section 1 55degC, section 11 35degC, exhaust air temperature chamber 65degC. Description of Spray Drying Unit: The atomization is done via rotary atomizer. The drying gas is introduced through the gas disperser and the atomized feed is mixed with hot air. The exhaust gas enters the cyclone where the particles are separated from the air. The product enters the Vibro Fluidizer where the second stage drying and cooling takes place. The exhaust air from the Vibro Fluidizer enters the bag filter where the particles are separated from the air. All the exhaust gas is cleaned in a wet scrubber before entering an incinerator. Main Components: feed system - feed pump for rotary atomizer, rotary atomizer. Main hot air system - Air intake filter, supply fan, gas fired air heater, gas disperser. Air system for vibro fluidizer - air intake filters, supply fan, dehumidifier, steam heated air heater. Drying system - drying chamber, Vibro fluidizer. Fines system - fan for conveying system, vortex valve, conveying cyclone. Ex chemicals use.
