FL- 5 Labotary Fluid Bed Equipment For Doing Pilot / Experiment High Efficient
Lab fluid bed dryer granulator overview:
The material in the Clean Hot gas flow (negative pressure) under the action of the suspension of the fluidization state, the surface of the hot air in full contact with heat evenly reached the heat exchange state, which has a very high efficiency.
With the appropriate spray system, and further improvement of the functional structure of the fluidized bed, the appropriate surface of the fluidized bed spray drying granulation, coating characteristics, which is a combination of drying, granulation, coating of multi-purpose process equipment.
Lab fluid bed dryer granulator Process Introduction
The granulation powder or coating with granular materials into the fluidized bed, cold air from the main engine behind the heating chamber into the first effect of the filter, heating to enter the air inlet temperature into the fluidized bed, the powder in the bed is fluidization, granulation with a binder from the infusion pump into a double-fluid atomizer, after atomization spray to the fluidization material.
The powder is bridged with each other and gathers into grains and grows or forms a film on the material to be coated, and the water evaporates out of the machine after being discharged from the air.
※ There is a blowdown device at the bottom of the main engine, which can quickly drain the water when cleaning machine
※ in the same container to complete the mixing-granulation-drying, reducing the process;
※ in closed-dense container operation, no dust flying, improve the operating environment;
※ The filter bag adopts anti-static filter material, the equipment operation is safe;
※ Binder atomizer Using multi-fluid spray gun, uniform atomization, high pass rate of finished products;
※ The use of round containers, easy to rinse, contact with the material part of stainless steel production;
※ Cylinder jacking type sealing, reliable sealing, simple operation;
※ The whole machine has good sealing and negative pressure operation.
Equipment structure Bottom spraying coating bed: Bottom spraying coating bed is a new type of particulate coating equipment which combines fluidization granulation technology with spray technology, which is widely used in Capsule granule and particle coating. The spray coating is placed on the bottom of the fluidized bed, and the material Guide tube is arranged to form a strict material running trajectory to obtain uniform and continuous coating. As the spray gun is placed in the bottom guide cylinder of the fluidized bed, and buried in the material layer, so the fog particles run short distance, no coating material loss, low production costs.
Structure Top Jet Boiling Bed: The spray gun is installed above the boiling fluidized bed, and the binder is sprayed on the powder in the boiling state to obtain the required particles. It is characterized by mixing-granulating-drying in the same machine once completed, with a double-trap filter bag system, clear ash thoroughly.
The heat exchange quantity is big, is advantageous to the drying, completes the granulation time short.
