1 Features:
1.1 spray drying tower drying speed. After centrifugal spray, the surface area is greatly increased. In the high temperature air stream, 95% -98% moisture can be evaporated instantaneously, and the drying time is only a few seconds.
1.2 The use of co-current spray-dry form can make the droplets and hot air flow in the same direction, although the hot air temperature is high, but the hot air into the drying room immediately with the spray droplets contact, the indoor temperature drop, and the material wet bulb temperature basic It is also suitable for heat-sensitive materials to dry.
1.3 spray drying tower use a wide range. According to the characteristics of materials, can be used for hot air drying, centrifugal granulation and cold granulation, most of the characteristics of large differences in the product can use this machine production.
1.4 As the drying process is completed in an instant, the finished product particles are essentially able to keep the droplets in a similar spherical shape, and the product has good dispersibility, fluidity and solubility.
1.5 production process is simplified, easy to operate and control. Spray drying is usually used for solutions with a solids content of less than 60%. After drying, no further crushing and screening is required to reduce the production process and simplify the production process. For the product size, bulk density, moisture, within a certain range, can change the operating conditions to adjust, control, management is very convenient.
1.6 in order to make the material from pollution and extend the life of equipment, where the material with the contact part, are made of stainless steel. The material is sprayed and atomized into particles, and the surface area is greatly increased. After drying with hot air, the drying process can be completed in a very short time. Under normal circumstances in the 100 ~ 150 ℃, 1 ~ 3 s can be evaporated 95% to 98% of the water. Since the drying process is completed in an instant, the finished product particles are substantially spherical in shape similar to the droplets, resulting in good dispersibility, excellent flushing and high solubility.
