Spray dryer is a widely applied processing equipment used in liquid process shaping and drying industry. Particularly it is suitable for producing powder, granulate or block solid product from solution, emulsion, suspending liquid and pumped paste liquid. Therefore, when the distribution of granulate size, final moisture, bulk density, granulate shape of finished product must be conformed to accurate standard, the spray drying is an ideal process. The product made by spray dryer features of good uniformity, fluidity, solubility, high purity and high quality.

After filtering and heating, the air enters air distributor at the top of the dryer. The hot air enters the drying chamber in the spiral from uniformly. By passing through the high-speed centrifugal atomizer at the top of the tower, the material liquid will be rotated and spray into extremely fine mist liquid beads, through the very short time of contacting with hot air, the materials can be dried into the finished products. The finished products are discharged continuously from the bottom of the drying tower and from the cyclone separator. The waste gas is discharged by blower.

The key point of the spray dryer is to pay attention to the material sticking to the tower, material moisture absorption, material collection, material protection and so on. For the wall sticking problem of materials, the wet materials should be paid attention to because the viscosity of the extraction solution is large. The particle size is large during atomization, and the centrifugal force obtained is also large. According to the general atomization diameter, the wall will definitely stick. Therefore, when designing the tower body, the diameter of the tower body should be large to ensure that it does not stick to the wall. Of course, the tower diameter cannot be expanded infinitely. Because the material contains a lot of glue, its hygroscopicity is very strong, so in the whole discharging process, the environment should keep low humidity. The average particle size of the centrifugal spray dryer is 120-140 mesh. Through a cyclone separator, 85% of the dry material can be recovered. The recovery rate can reach 93%-96% through the two-stage cyclone separator. The tower has better use the two-stage cyclone separator to make the dry powder yield reach 93%. At the same time, the wet dust collector is added to make the yield of the material reach the highest. Material protection is actually the most important. Generally, the temperature of the general extract is low. It will deteriorate when it is in high temperature. Therefore, it is very important to use the appropriate temperature to dry in the spray drying process. To achieve the same conditions, the output is high, the quality of finished products is good, and the protection of dry products is also important. The tower made by UPMACH is determined by combining the practical situation and the special situation of the extraction liquid. The diameter of the tower is relatively large to avoid wet material sticking to the wall, and the pneumatic vibrator is installed in the cone part to protect the dry powder from deterioration when it is accumulated in the cone, so that the dry powder can reach the outlet as soon as possible. In addition, a cold air jacket is added on the tower body to avoid the damage of a small amount of dry powder accumulated in the cone part.
