Core working principle and cross industry application analysis of FG series boiling dryer
1、 Fluidized drying mechanism
Negative pressure boiling principle: Clean air is heated to the set temperature by a heater, and then introduced into a hopper filled with perforated plates from the bottom by a fan. Wet materials form a three-dimensional boiling state under negative pressure, achieving dynamic contact heat transfer between materials and hot air.
Anti adhesive design: Equipped with a low-speed mixing device to forcefully disperse high humidity materials, avoiding the formation of clumps or channeling, ensuring uniform fluidization of viscous particles with a moisture content of over 15%.
Closed loop control system: Closed negative pressure operation combined with anti-static filter material, dust overflow concentration is controlled below 50mg/m ³, meeting the strict requirements of GMP for cross pollution.
2、 Multi domain application practice, including but not limited to
1. Pharmaceutical industry
Combined with the wet granulation machine for drying, the qualified rate of particle disintegration time limit is over 98%, and the circular fluidized bed structure achieves no dead corners for cleaning.
The closed negative pressure operation effectively prevents the loss of active ingredients in drugs, and the material yield exceeds 99%.
2. Food processing
For high expansion materials such as konjac, a tipping design is used to accommodate batch processing capacities of 100-1100kg.
Hot air dynamic adjustment technology reduces drying time by 50% and energy consumption by 30%.
3. Chemical industry field
When processing polyacrylamide, stirring and fluidization should be coordinated to prevent clumping, and the final moisture content should be stable within 0.2%.
Suitable for particle materials with a diameter of 0.1-6mm, efficient gas-solid contact enables rapid evaporation of water.
