Centrifugal atomizer; Characteristics
Centrifugal atomizerThe characteristics of the centrifugal dryer are basically determined by the characteristics of the atomizer.
(1) Centrifugal spray drying does not require strict filtration equipment. If there is no fibrous liquid in the feed liquid, the liquid channel is basically not blocked;
(2) It can adapt to higher viscosity liquids (compared to pressure spray drying);
(3) Since the atomizer speed is easy to adjust, it is easier to clear the product particle size. Narrow particle size distribution;
(4) When adjusting the processing capacity, there is no need to change the working state of the atomizer. When the feed speed changes within 25%. The same product is available.
The fog caused by (5)/ kloc-0/ is basically the same level. The droplets move in a combined radial and tangential direction with almost no initial axial velocity, so the diameter of the dryer is relatively large. The space in the drying room can be used;
Centrifugal atomizer Advantages of the equipment:
The drying speed is fast and the surface area of the atomized liquid is greatly increased. in thermals. 95%-98% of water can evaporate instantly. The drying time is only 10 to 10 seconds, which is especially suitable for drying heat-sensitive materials. All products are spherical particles. Uniform particle size, good fluidity, good solubility, high purity, good quality; wide range of applications; according to material characteristics. Hot air drying or cold air granulation can be used, which has strong adaptability to materials; the operation is simple and stable. Easy to control. Easy to automate.
The high-pressure pump generates pressure spray, causing the wet material to be sprayed out from the nozzle. The inner surface of the nozzle is made into a spiral groove. The outlet has a cone angle of approximately 700°. The wet material will rotate along the small grooves, forming a spiral circular motion. It is ejected at high speed from the cone-shaped nozzle. Wet droplets of material are elongated and thinned, forming filaments that break into droplets. The higher the spray pressure, the smaller the nozzle diameter, the smaller the mist droplets, and the larger the mist droplets, the worse the situation will be. In this case, it is necessary to set the nozzle. And monitor its working status at all times to ensure that there are no droplets during the spraying process.
