Benefits of Fluidized bed spray granulation

Fluidised bed spray granulation produces granules of the desired particle size and high chemical stability through targeted particle structure and temperature control.
Granulating creates free-flowing solids, directly from the suspension / solution.

Pesticides are often produced in the aqueous phase as a suspension. A dust-free product (application safety) must be created. Targeted grain structure results in granules in the desired grain size and optimal temperature control enables high chemical stability.

Fluidized bed spray granulation has become firmly established as a drying process in recent years, because it can convert a solid-containing liquid into a dry product in a single process step.

Advantages of spray granulation
(1) the possibility of influencing the resulting particle size and bulk density
(2) the extremely precise control of product temperature as well
(3) the generally low process temperature contribute to this success.

A characteristic of the process is that the liquid is sprayed onto its own particles, which are intensively mixed and dried in the fluidized bed. As a result of the spraying, the particles grow. If you have exceeded a defined, adjustable size, they will be discharged. This creates a continuous process in which only liquid is added and only dry product is withdrawn.

Spray granulation is a convective drying process, i.e. energy is supplied via heated air. This also takes care of the evaporation of the water. The special feature of the process is the combination of spraying the liquid with drying in the fluidized bed. When spraying, the liquid is dispersed into fine droplets. This creates a large surface area. One liter of water can produce 15 billion droplets with a surface area of ​​120 m². These droplets are sprayed onto a fluidized bed, which also provides a very large surface for drying.

Further applications for spray granulation are:

  • Production of dust-free granulates (for liquids with a high solid content)
  • Drying at low temperatures.

Advantages of fluidised bed spray granulation are:

  • Top spray
  • Continuous operation
  • Drying and shaping in one step

Fluidised bed Coating can be used when a solid must be coated with another substance to obtain different properties or a protective cover. Coating is always used when a solid must be coated with another substance to obtain different properties or a protective cover. Various micro-organisms (bacteria, yeast) have a positive, physiological influence. Often, they are very sensitive to environmental influences. Resistance to gastric acid can also be required. Coating with wax, shellac etc. protects the dried organism.

Successful fluidized bed spray agglomeration with Ammag
Agglomeration is the correct process when a powder is to be turned into an easily pourable and soluble product, for example in perborate production. Filter dust accumulating during perborate production cannot be reused and must be processed by dissolving. The fluidised bed agglomeration with a suitable binding agent creates a saleable product.

Possible processes with fluidised bed granulators
Due to their design, fluidised bed technology systems can be used very flexibly. Fluidised bed technology processes benefit from: * the intensive mixing of the original solids * the large available particle surface * the fine distribution of liquid droplets A fluidised bed consists of a bed of solid particles that are lifted by an upward flow of air and thereby converted into a liquid-like state, i.e. fluidised. By spraying a solid-bearing liquid with an average droplet size of 50 µm (1 liter of water = 15 billion droplets) onto the fluidised bed, granules or agglomerates can be produced. Further possible steps are coating or matrix encapsulation phases. After any subsequent drying or further thermal treatment, the finished product can easily be discharged from the system. Addition of liquid is carried out with a positive-displacement pump by spraying, using a two-substance nozzle. Compressed air is generally used for nebulization. The use of other gases (for example: steam, nitrogen) is possible. The filtered and heated supply air
