Common types of spray dryer on the market

　　Generally, there are three kinds of spray dryer: centrifugal, pressure and airflow drier. Next I will introduce their respective functional characteristics, hoping to help you.

　　Centrifugal spray dryer

　　This is one of the most widely used dryers in the market. Generally, its drying time is very short, only about 5 to 15 seconds. The atomizer it uses is centrifugal, and has the general characteristics of spray dryer, such as high efficiency, fast drying speed, and the process of grinding products. And the drying process is simplified a lot, so it is more suitable for continuous drying production mode, and because of the special air distribution device, it has a certain degree of help in reducing the resistance of the drying equipment.

　　Two. Pressure spray dryer

　　This is the biggest in the completion of drying products at the same time, can also complete the task of granulation. The slurry is transported by diaphragm pump under high pressure, and then atomized. It can be used in a wide range. According to the different properties of the materials to be dried, it can be dried with hot air or granulated with cold air. It is convenient for people to choose and has a strong material adaptability. After the pressure spray dryer, the product is often spherical particles, although its drying time is very short, but the product is also of high purity and good quality, even the product particles are often uniform in size, which can be said to be extremely efficient.

　　Three. Airflow spray dryer.

　　This type of spray dryer is more operational and controllable, and is more conducive to control its drying process. It is also very popular due to its remarkable flexibility in manipulation. When it is used to dry products, the operating conditions of the dryer can be adjusted appropriately according to the different properties of the slurry. In a certain range, it is convenient to manage and control the drying of products. Generally speaking, the airflow spray dryer is more suitable for materials with high viscosity, for example, paste material or paste material. For this kind of material, its drying effect is far more than that of other kinds.

　　According to the different nature of the material and the different production needs, we should choose the most suitable spray drying machine for drying production. It should be noted that different spray drying machines require different amounts of material, and their differences should be paid more attention when used.
