Griffin Technology is a professional spray dryers supplier. We can supply two types of spray drying equipment, one is the centrifugal spray dryer, and the other is the pressure spray dryer. Many customers are very confused about which one to choose. Today, we will give a general description and comparison of these two spray dryers to provide customers with a little help when making a choice.
First of all, these two dryers belong to spray drying. We distinguish them by the difference between one atomization form of these two spray dryers, and the other is to use the high-speed rotating atomizer For atomization, we call this a centrifugal spray dryer. The other is a booster pump such as a high-pressure diaphragm pump. The raw material passes through the pressure of the pump and then goes to the spray gun at the feeding place. Muzzle atomization, this we call pressure spray.
Features Of Centrifugal Spray Dryer
- Compared with the pressure spray dryer, the centrifugal spray dryer is the most intuitive.
- The product particle size produced by the centrifugal spray dryer is relatively fine and uniform.
- In terms of design and appearance, the centrifugal spray dryer is higher than that of evaporation.
- The amount of pressure spray drying is half as short, and the height of the workshop is not as high.
- Centrifugal spray is suitable for our conventional products with better fluidity and lowers solid content.
Features Of Pressure Spray Dryer
- Compared with the centrifugal spray dryer, the product produced by the pressure spray dryer can be granular, with better fluidity and better instant solubility, similar to milk powder.
- The design height is higher, which will lead to a corresponding increase in investment in industrial facilities such as workshops.
- The pressure spray dryer is also suitable for direct spray drying of some viscous products, such as coffee, non-dairy creamer, and other products.
