Spray drying equipment is classified according to the method of atomization
Pressure spray drying method:
①Principle: Using a high-pressure pump, at a pressure of 70 to 200 atmospheres, the material is polymerized into a mist of 10 to 200 particles in direct contact with hot air through an atomizer (spray gun) for heat exchange, and drying is completed in a short time.
② Pressure spray atomization device: M-type and S-type, with guide grooves that make the liquid flow rotate, the axis of the M-type guide groove is perpendicular to the nozzle axis, and does not intersect with it; the axis of the S-type guide groove is at a certain angle to the horizontal. The purpose is to try to increase the turbulence of the solution during spraying.
