The FLP Series Fluidized Bed Granulation Dryer is a highly efficient equipment that integrates mixing, granulation, and drying functions. It is widely used in the pharmaceutical, food, and chemical industries. The core technology is to use the fluidization and heating of air to complete the granulation and drying of materials. The FLP Series Fluidized Bed Granulation Dryer produced by Jiangsu Bohong Drying Equipment Co., Ltd. has unique working principles and advanced technical advantages, and has been widely used in many industries. It not only improves the fluidity, solubility, and production efficiency of materials, but also has high safety and compliance with GMP standards. As industrial technology continues to advance, the FLP Series equipment will continue to provide strong support for the development of the pharmaceutical, food, and chemical industries.

1. The Working Principle of FLP Series Fluidized Bed Granulation and Drying Machine

The working principle of the FLP series fluidized bed granulation dryer can be simply described as fluidizing the material with airflow, spraying adhesive to make powder particles agglomerate and take shape, and then drying the formed particles continuously with hot air.

First, the powder particles of the material are placed in a feed container, commonly known as a fluidized bed. The material in the fluidized bed is brought into a fluidized state by introducing heated air. At this point, the material in the container forms a ring-shaped fluidized state, with the particles dispersed from one another, creating a motion similar to suspension. This state allows the material particles to be fully exposed to the air, and the air can quickly pass through the gaps between the particles, achieving uniform heating of the material.

Then, during the fluidization process, the equipment sprays the adhesive solution through nozzles, uniformly spraying it into the material particles in the fluidized bed. At this point, the material particles begin to adhere to each other, and several particles aggregate into clumps, forming granules containing adhesive. Due to the continuous action of hot air, the water in these granules evaporates quickly, and the adhesive gradually solidifies. As this process is repeated, eventually, spherical particles with an ideal multi-porous structure are formed.

The process of granulation and drying is continuous. The material starts in a fluidized state and is then bonded by the binder, eventually being dried and shaped by air to form granules. The entire process is highly efficient and precise, ensuring uniformity and quality of the granules.

2. Product Features of FLP Series Fluidized Bed Boiling Granulation Dryer

The FLP series fluidized bed boiling granulation dryer has many advantages in structure design and operational performance, which make it widely used in industrial production:

2.1. **Improving material flow and reducing dust**

By granulation, the material flow is significantly improved. This granulation technology reduces the adhesion between powder particles, making the particles more uniform and improving fluidity. At the same time, due to the shaping process, the phenomenon of dust flying is greatly reduced, improving the production environment and reducing the harm to operators.

2.2. **Improved dissolution performance**

By granulation, the solubility of the material is also optimized. The particle shape is uniform, the particle size is smaller, and the internal structure is porous, which increases the specific surface area of the material and significantly improves the dissolution rate. This is of great significance for pharmaceutical and food products that require rapid dissolution.

2.3. **Multi-function in One Machine**

The FLP series fluidized bed granulation dryer integrates mixing, granulation, and drying functions in one machine, simplifying the production process. Traditional granulation equipment often requires separate use of different equipment for mixing, granulation, and drying, while the FLP series equipment achieves one-step operation, allowing all processes to be completed in one machine, greatly improving production efficiency and reducing equipment investment costs.

2.4. **Excellent Safety Performance**

The fluidized bed boiling granulation dryer uses anti-static filter cloth, effectively preventing the accumulation of static electricity and avoiding the risk of fire or explosion. In addition, the equipment is equipped with explosion-proof pressure relief holes, which can release pressure in time in case of an accidental explosion, ensuring the safety of the equipment and operators.

2.5. **Complies with GMP standards, easy to clean and operate**

The FLP series fluidized bed granulation dryer equipment is designed without dead ends, so that the material can be fully mixed and dried within the equipment. In addition, the material loading and unloading is lightweight, reducing the difficulty of operation. At the same time, the equipment is easy to clean, which can fully comply with the GMP standards for pharmaceutical production, ensuring the quality of the product and the standardization of production.

3. Application Range of FLP Series Fluidized Bed Boiling Granulation Dryer

一、FLP系列流化床沸腾制粒干燥机的工作原理

FLP系列流化床沸腾制粒干燥机的工作原理可以简单描述为通过气流流化物料，并喷入粘合剂，使粉末颗粒聚集并成型，再通过热空气的不断干燥作用使颗粒成型。

首先，物料的粉末颗粒被放置在原料容器中，即所谓的流化床。流化床中的物料通过引入的加热空气进入流化状态。此时，物料在容器内呈现出环形流化，颗粒彼此分散，形成类似悬浮的运动状态。这样的状态使物料颗粒充分暴露在空气中，空气可以迅速穿过颗粒之间的空隙，实现对物料的均匀加热。

接着，在流化过程中，设备通过喷嘴将粘合剂溶液雾化，并均匀喷入流化床中的物料颗粒中。此时，物料颗粒之间开始相互黏结，若干颗粒聚集成团，形成含有粘合剂的团粒。由于持续受到热空气的作用，这些团粒中的水分迅速蒸发，粘合剂也逐渐凝固。随着这一过程的反复进行，*终形成具有理想多微孔结构的球状颗粒。

制粒与干燥的过程是连续的，物料从流化状态开始，经由粘合剂的作用凝聚，*终通过空气干燥成型，整个过程高效而精准，确保了颗粒的均匀性与质量。
