The invention provides a
spray drying machine used for
solid dye production. The
spray drying machine used for
solid dye production comprises a supporting pedestal plate, a
drying tank, supporting columns, an atomizer, a dye liquid inlet
pipe, a
nozzle, a hot air conduit, a
discharge valve, a blower fan, a
cold air purifying filtering tank structure, an anti-blocking hand-operated material overturning
sheet structure, a discharging airborne-dust-prevention
cyclone separator structure, an
ultrasonic vibration particle shaking-off ring structure, an
air heating tank structure, a gas guiding connecting
pipe, a secondary separation conduit, a collecting tank, an induced draught fan, and an
exhaust gas discharge connecting
pipe. According to the
spray drying machine, a purifying tank, a sealingtank bovver, an air inlet pipe, a stainless steel pipe filter screen, a
nylon filter screen, and a
HEPA filter layer are adopted, so that it is beneficial for filtering
impurity removing of dried air, and filtering purifying of particles or harmful gas in the air is realized; a hand-operated rocking bar, a material overturning sheet, a
ball bearing, a hand-operated wheel, and a
handle are adopted, so that it is beneficial for dredging and blocking prevention in
discharge process of dried
solid dye particles.
