Working principle and core characteristics of multifunctional fluidized bed granulation and coating machine
Date: 2025-05-20Read: 5
1、 Working principle
1. Fluidization process
Heating air is introduced from the bottom of the equipment through a blower, causing the material to suspend and form a fluidized bed under the action of the airflow. At this point, the materials are uniformly mixed, and the heat exchange efficiency is significantly improved.
2. Spray system
Granulation: The atomized adhesive is sprayed onto the surface of the fluidized powder, and the particles gradually increase through repeated wetting and bonding.
Coating: The coating solution is evenly applied to the surface of particles, tablets, or microspheres through a bottom spray or side spray system, and then combined with hot air drying to form a film layer by layer.
3. Heat exchange and drying
Suspended materials come into direct contact with hot air, causing rapid evaporation of moisture and high drying efficiency. Fine powder is recovered through a filtration device and re enters the granulation cycle.
2、 Core Features
1. Multi functional integration
Support multiple processes such as mixing, granulation, coating, drying, cooling, etc., reducing the need for equipment switching.
2. Efficient drying and energy saving
Fluidized design ensures uniform heating of materials, with a drying speed 30% -50% faster than traditional equipment, and supports hot air circulation.
3. Precise control and flexibility
The temperature, humidity, spray rate and other parameters are adjusted through the PLC control system to meet the requirements of different materials and particle sizes (such as 20-100 mesh particles).
Stepless adjustment of air intake, compatible with various forms of processing such as powder, pellets, capsules, etc.
4. Structural optimization and compliance
Sealed circular structure, compliant with GMP cleanliness standards, supports rapid cleaning.
Equipped with a swirl air distributor and anti-static filter material to reduce dust residue and cross contamination.
5. Wide applicability
Suitable for pharmaceutical (sustained-release tablet coating, traditional Chinese medicine extract granulation), food (instant granules), chemical (pigment granulation) and other fields.
