Custom Lab Fluid Bed Dryer Granulator FL Model Low Noise Stable Performance

Lab fluid bed dryer granulator overview:

The material is suspended in a fluidized state under the action of a clean hot gas flow (negative pressure), and its surface is completely in contact with the hot air, and the heat is uniformly heated to a state of heat exchange, thereby having an extremely high efficiency. With a suitable spray system and further functional structure improvement of the fluidized bed, the fluidized bed spray drying granulation and coating characteristics are closely displayed, which means that it is a combination of drying, granulation and coating. Use process equipment.

Lab fluid bed dryer granulator Process Introduction

The granulated powder or the granular material for coating is put into the fluidized bed, and the cold air enters from the heating chamber at the rear of the main machine, and is filtered by the primary effect, and the heater is heated to the temperature required for the inlet air, and then enters the fluidized bed, the powder Fluidized in the bed, the granulation binder is fed into the two-fluid atomizer by the infusion pump, and is atomized and sprayed to the fluidized material. The powders are bridged to each other and grow up to form a film on the material to be coated, and the water is volatilized and then taken out of the machine by the exhaust air.

※ There is a sewage device at the bottom of the main unit, which can quickly drain the water when cleaning the machine.

※ Mixing-granulation-drying in the same container reduces the process;

※ Operate in a closed container, no dust flying, improve the operating environment;

※ The filter bag is made of anti-static filter material, and the equipment is safe to operate;

※ The binder atomizer adopts multi-fluid spray gun, which is evenly atomized and has high qualified rate of finished products;

※ It adopts a round container for easy washing; the part in contact with the material is made of stainless steel;

※ It adopts cylinder top lift seal, reliable sealing and simple operation;

※ The whole machine has good sealing performance and negative pressure operation.

◆ Equipment structure

Bottom spray coating bed: The bottom spray coating bed is a new type of microparticle coating equipment that combines fluidized granulation technology and spray technology. It is widely used in capsule granules and microparticle coating. The bottom spray coating puts the spray gun on the bottom of the fluidized bed and is equipped with a material guiding cylinder to form a strict material running track to obtain a uniform and continuous film. Since the spray gun is placed in the guiding cylinder at the bottom of the fluidized bed and buried in the material layer, the mist has a short running distance, no coating material loss, and low production cost. structure

Top spray boiling bed: The spray gun is placed on a boiling fluidized bed, and the binder is sprayed on the powder in a boiling state to obtain the desired particles. It is characterized by a combination of mixing-granulation-drying in one machine at a time, with a dual-collection filter bag system and thorough cleaning. The heat exchange amount is large, which is good for drying, and the granulation time is short.
