The SED-50PG2-I is a centrifugal (rotary disc) atomizer spray dryer with 50 kg/hr water-evaporation capacity, configured with 316 stainless steel for all product-contact surfaces (SUS304 elsewhere) for higher corrosion r
مبدأ العمل
Open-cycle co-current spray drying. Ambient air is filtered(primary + medium efficiency), pressurized by a 1.5 kW forced-draught fan(4-72 No.4.5A), heated electrically(150 kW) to 150–160 °C, and enters the drying chamber via inlet volute and adjustable swirl-vane distributor. A 0.55 kW screw pump(DPMFXAA600/0.5, 600 L/h, 0.5 MPa) delivers feed liquid to the gear-driven centrifugal atomizer(1.5 kW drive,Φ135 mm disc, 12,600–20,000 rpm via VFD; oil pump 0.37 kW + cooling-water circulation pump 0.37 kW). Atomized droplets contact hot air co-currently and dry within seconds. Powder is collected by twin cyclones(with rotary discharge valves, 2 × 0.55 kW) plus a bag filter; humid exhaust is pulled by an 11 kW induced-draught fan(9-26 No.5.6A) and silenced before the stack. Ten pneumatic knockers(7 × SK60 on straight section + 3 × SK40 on cone) prevent powder build-up; an explosion vent(Φ159 mm) opens at 3000 Pa.
