Intelligent boiling drying equipment

Intelligent boiling drying equipment (also known as fluidized bed dryer), with "hot air penetration+particle suspension+precise temperature control" as the core technology, achieves high-quality drying effects of rapid dehydration, complete particle shape, non stick wall, and low dust. It is widely used for industrial drying needs of various materials such as tablet particles, traditional Chinese medicine extract particles, instant powder, probiotic preparations, catalyst carriers, etc.

Introduction to Boiling Drying Equipment Products

In industries such as pharmaceuticals, food, chemicals, feed, and fine chemicals, efficient, uniform, and gentle drying of wet granules or powders is a key step in ensuring product quality stability and production continuity. In view of the low drying efficiency of traditional ovens, uneven drying of fluidized beds, and large investment in spray drying, we launched a new generationIntelligent boiling drying equipment(also known as fluidized bed dryer), with "hot air penetration+particle suspension+precise temperature control" as the core technology, achieves high-quality drying effects of rapid dehydration, complete particle shape, no sticky walls, and low dust. It is widely used for industrial drying needs of various materials such as tablet particles, traditional Chinese medicine extract particles, instant powder, probiotic preparations, catalyst carriers, etc.

1、 Working principle and structural composition

Boiling drying equipment based onFluidization technologyAfter being filtered through three stages of primary, medium, and high efficiency, clean hot air is sent by a fan to the heater for heating, and then evenly enters the drying room from the bottom porous distribution plate (or gap type air cap). When the airflow velocity reaches the critical fluidization velocity, wet particles are in a "boiling" state under the action of hot air - suspended, rolling, and fully exposed to hot air. Moisture quickly vaporizes and is discharged with exhaust gas, thereby achieving efficient heat and mass transfer.

The whole machine is mainly composed of the following modules:

1. Air intake systemIncluding a fan, primary/medium/high-efficiency filters, electric heater or steam heat exchanger, to ensure clean inlet air and controllable temperature;
2. Drying machineCylindrical or square stainless steel chamber, with optional capacity;
3. Fluidized distribution boardLaser cutting micro porous plates or detachable hood structures to ensure uniform airflow distribution and avoid channeling or dead zones;
4. Separation systemThe top is equipped with a cyclone separator and a bag filter to recover fine powder and meet the emission standards for exhaust gas;
5. Discharge deviceQuick opening butterfly valve or automatic discharge valve, supporting closed docking with the next process;
6. intelligent control systemPLC+touch screen, real-time monitoring and adjustment of inlet air temperature, air volume, drying time, pressure difference and other parameters, supporting process curve storage and electronic batch recording.

2、 Core advantages and technological innovation

1. High drying efficiency and low energy consumption
   Particles in boiling state are in full contact with hot air, and the heat transfer coefficient is higher than that of static drying. The drying time for typical materials (such as wet granulation particles) is only 15-40 minutes, which is shorter than that of an oven. Hot air can be partially recycled.

2. Excellent particle quality

   • Complete grain shapeNo mechanical stirring to avoid particle breakage;
   • Uniform moisture contentThe moisture deviation of the entire batch of materials is small;
   • Non stick wall lumpsContinuous boiling motion prevents material accumulation, especially suitable for high sugar and high viscosity materials such as traditional Chinese medicine extracts;
   • Consistent colorLow temperature drying effectively prevents degradation or browning of heat sensitive components.

3. High cleanliness and compliant design

   • Fully enclosed structure, negative pressure operation, to prevent dust overflow;
   • Quick installation clamp connection for easy CIP cleaning;
   • The filtering system meets the requirements;

4. Multi functional expansion capability
   This device is not only used for drying, but can also be upgraded toMulti functional fluidized bedTo achieve:

   • Top spray granulationSpray adhesive while drying to complete one-step granulation;
   • Bottom spray coatingUsed for pellet coating and sustained-release layer coating;
   • Side spraySuitable for the preparation of high drug loading particles.
     Simply install a spray system and peristaltic pump to achieve the integration of "drying granulation coating".

5. Intelligence and Data Traceability
   The system pre sets multiple material drying templates and can be started with just one click; Automatically record key parameters such as temperature curve, pressure difference changes, and operating time, and generate electronic batch records in PDF format to meet requirements.
