一、工作原理及应用范围介绍Introduction of Working Principle and Scope of Application
The boiling pelletizing method incorporates spray technology and fluidization technology. Powdery material is put into the hopper and enclosed. Under the action of negative pressure hot air, the powdery material inside the bed suspends and circularly flows in the fluidizing state. It is uniformly mixing when fluidizing, and at the same time mist-like binder is injected in to moisten the powder in the container so that the powder congeals into small loose granules. During the pelletizing, the hot air dries the material efficiently; water evaporates unceasingly; the powder congeals consistently, so ideal and uniform porous spherical powder granules are produced finally. The boiling fluidized pelletizing drier is to complete the mixing, pelletizing and drying processes at a time inside a same equipment, therefore it is also known as “one-step pelletizing drier". This unit adopts batch drying production.
This equipment is widely applied to pelletizing and coating the tablets, dissolved medicines, juice granules and condiment etc in the pharmaceuticals and food industries, and also applicable to pesticides, chemical engineering pesticides, fodder, chemical fertilizer and dyes etc.
1. Pelletizing the powder improves the mobility, decreases flying dust and maintain the uniformity and constancy of material quality.
2. Pelletizing the powder improves the dissolving property of powder.
3. The mixing, pelletizing and drying processes are completed in a same equipment, which improves the overall efficiency.
4. Antistatic filter cloth is adopted and pressure relief hole is provided. The equipment operates safely.
5. The equipment is free of dead angles, easy and quick to load and unload the material and easy to be cleaned. It complies with “GMP" specifications.
6. It is possible to achieve full inligence, digitization and CIP etc as required.
7. The binder atomizer adopts multi-fluid spray gun which produces uniform fog droplets. The pass rate of finished products is improved greatly.
