SUS304 PGL-B -3 Series Spray Drying Granulator (Lab type),heating source is electricity , capacity 1~3kg per batch
Product Description
Spray Drying granulator machine makes use of spray and fluid bed technology to realize mixing, granulation and drying in one container. The fluidized powder is wetted by the spaying the extract until agglomeration occurs. As soon as the size of the granule is reached . spraying is stopped and the wet granules are dried and cooled .
The powder granule in vessel (fluid bed) appears in the state of fluidization. It is preheated and mixed with clean and heated air. At the same time the solution of adhesive is sprayed into the container. It makes the particles become granulating that contains adhesive. Being of unceasing dry through hot air, the moisture in the granulating is evaporated. The process is carried out continuously. Finally it forms ideal, uniform and porous granules.
Spray agglomeration moves very small, powder particles in the fluidized bed where they are sprayed with a binder solution or suspension. Liquid bridges are created that form agglomerates from the particles. Spraying continues until the desired size of the agglomerates is reached.
After the residual moisture in the capillaries and on the surface has evaporated, hollow spaces are created in the granulate while the new structure is solidified throughout by the hardened binder. The lack of kinetic energy in the fluidized bed results in very porous structures with plenty of internal capillaries. The usual size range of the agglomerate is from 100 micrometers to 3 millimeters, while the starting material can be micro-fine.
Features
1. Integrate spraying, drying fluid granulating in one body to realize granulating from liquid in one step.
2. Using the process of spraying, it is particular suitable for micro auxiliary raw materials and heat sensitive raw materials. Its efficiency is 1-2 times than the one of fluidized granulator.
3. The final moisture of some products can reach 0.1%. It is equipped with powder returning device. The rate of granule forming is more than 85% with 0.2-2mm of diameter.
4. The improved inner roller multi-flow atomizer can treat the liquid extract with 1.3g/cm3 of gravity.

Sample on model choice : Suppose that are 120kg liquid extract (include 30% solid )and 60kg seed II in one vessel ,from I and II,we can get theoretical product amount M=mI+mII=120kgx30%+60kg=96kg ,working time T=120kg/30kg/h=4h ,from the parameter table we can find that the fluidization amount is inside the standard loading range .if we require two batches in one duty time ,PGL-30B is ok.
