Advantages of pressure spray dryer
◎ The drying speed is fast, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95% -98% of the water can be evaporated in an instant. The time to complete the drying takes only ten seconds to tens of seconds, which is particularly suitable. Used for drying heat-sensitive materials.
◎ All products are spherical particles with uniform particle size, good fluidity, good solubility, high product purity and good quality.
◎ Wide range of application. According to the characteristics of the material, it can be dried with hot air or granulated with cold air, which has strong adaptability to the material.
◎ The operation is simple and stable, the control is convenient, and it is easy to realize automatic operation.
Pressure spray is the use of high pressure produced by a high-pressure pump to eject wet material from the nozzle. The inner surface of the nozzle is made into a spiral groove with a taper angle of about 700 at the outlet. The wet material will form a rotating spiral along the groove Moving in a circle and ejecting from the conical nozzle at a very high speed, the wet material droplets are elongated and thinned to form filaments and break into mist droplets. The higher the spray pressure and the smaller the diameter of the spray hole, the smaller the sprayed droplets; otherwise, the larger the droplets.
