    Description
    FLP multifunction granulating coating machine is composed of Fluidized drying - Fluidized granulating - Top spray granulating - bottom spray coating - drying function etc. It is suitable for the granulation of pharmaceutical, foodstuff, health products, and chemical industry.  Such as Tea polyphenols granulating, Omeprazole slow-release, Chinese traditional capsule’s granulating, Coating for cold relief capsule granule, radix isatidis  granulating, Chinese traditional medicine moisture proof coating, antibiotic granulating and coating etc.


    Principle
    Spray coating can be performed – usually in batch processing – in all fluidized bed systems. For some coating applications, a continuous process is also available. The film material is applied as a solution, suspension or melt. Caution should be taken here that no liquid bridges form during application in order to avoid undesirable agglomeration.
    When coating using a solution or a suspension, the liquid serves to transport the solids to the surface of the particles. When a melt is used for coating, in contrast, the coating material is one-hundred percent spreadable. This assures outstanding coating qualities.
    Coating can take place as top spray, t bottom spray or rotor process, depending from which direction the particles are being sprayed. These methods can all be performed in a single, modern fluidized bed system. 

    Function
    ▪ Tangent spray technique pelletizing, covering, coating
    ▪ Top spray techniquegranulating
    ▪ Bottom spray techniquecoating
    Tangent spray techniquethe material in the fluid bed is pushed upward by the hot air flow, it will do regular spin rolling movement in the specially designed container with the influences of centrifuge of the rotary plate, centripetal force of material container, the air flow back and the gravity. The liquid sprayed at a tangent direction make the material into core of pills, which are coated by powder from tangent spraying to get required tighten fine pellets.
    Top spray technique the material in the fluid bed forms upward. Flowing state pushed by the hot air flow, then combined into granules gradually by the liquid sprayed from upward, and irregular granules will be gotten after drying.
    Bottom spray technique the material is pushed upward from the bottom of the flow leading pipe by hot air flow and sprayed back, and coating liquid is sprayed from bottom of the flow leading pipe ,and coated onto the materials moving in the same direction to achieve the coating purpose.


    Application
    Mixing: For various kinds of fluidizing materials, such as powder, granules, micro-granule etc. Because of multi-dimensional movement (horizontal, tangent and radial direction), the mixing effect is very good.
    Granulating: Spray adhesive onto powder to produce granules with various diameters.
    Coating: Efficient for to coat powder, granules and micro-granules.
