Then the atomization system is switched off and fanulat drying starts. At the end of the whole fanulation cycle, fan 8 is automatically switched off and air supply to the calorifier unit is stopped. The product tank is lowered and the granulate enters the pelletizing process. To avoid entrainment, the air is supplied at a low speed. It is a wheeled apparatus, so it is very convenient for transportation. Technical characteristics of the apparatus type SG: single load: 30-100 kg; duration of granulation and drying: 25-120 min; drying temperature: 20-80 ° C; power consumption: 20 kW. The advantages of this apparatus are in the reduction of the production cycle and production area, reduction of the amount of equipment used and reduction of the labor intensity of the process. Modern devices SG-30 are equipped with a software control panel, granulating liquid is atomized by pneumatic nozzles. However, the specificity of each drug prepatars is such that according to the proven technology of granulation with the use of SG unit another substance in this mode will not be granulated. In such a situation, it is necessary to work out the modes again, to determine the quantity, quality, speed of granulating liquid supply, etc.

Glatt batch fluidized bed granulators. These machines combine the processes of granulation, agglomeration, drying and coating, using top and bottom atomization of granulating liquid.
For batch granulation, the dry feedstock is loaded into a receiving container. There it is agitated in a turbulent flow of heated gas while being kept in suspension and agglomerated (granulated) by spraying a suitable binder. The product is then dried to a certain residual moisture content in a process characterized by high heat and mass transfer coefficients. The batch size in various fluidized bed batch machines ranges from 20 g to 1500 kg.
An innovation in fluidized bed technology was Glatt’s development of the SpinFlow bottom, which gives the fluidized bed an additional rotational motion. The resulting tangential forces result in higher granulate density, good flowability, uniform particle size distribution and reduced fine dust formation. The design of this bottom is the basis for an optimal granulation production process in the fluidized bed plant and produces ideal granules for subsequent process steps.
