The PGL series fluidized bed spray dryer produced by Jiangsu Bohong Drying Equipment integrates spray drying and fluidized granulation into one, is a highly integrated, highly efficient modern drying equipment. Its design concept is based on one-step granulation, especially suitable for processing micro-additives and heat-sensitive materials, with high efficiency and reliable features.

1. PGL Series Fluidized Bed Spray Drying Granulator - Product Features

1.1. **Combines spray drying and fluidized granulation in one**

The core advantage of the PGL series fluidized bed spray dryer granulator lies in its integration of spray drying and fluidized granulation processes. Traditional drying and granulation processes often require two or more steps, but the fluidized bed spray dryer granulator achieves one-step granulation, simplifying the process and improving efficiency. Not only does it reduce the number of operating steps, but it also reduces energy consumption and production costs, resulting in a significant improvement in production efficiency.

1.2. **High-efficiency granulation, high yield**

The granulation rate of the fluidized bed spray dryer can reach 95% or more, and various materials with different characteristics can be produced into granule products with particle sizes ranging from 0.2 to 2mm. Compared with traditional FL flash granulators, the efficiency of PGL series equipment has been improved by 1-2 times. Such improvement makes production more efficient and is particularly suitable for industries such as pharmaceuticals, food, and chemicals that have strict requirements for granule products.

1.3. **Low moisture content**

The fluidized bed spray dryer granulator has been optimized to achieve a water content of as low as 0.1% for the product. This extremely low water content is particularly important for certain specialized products, especially in the pharmaceutical or food industries, such as preventing product spoilage and extending shelf life. The fluidized bed spray dryer granulator performs particularly well in handling heat-sensitive materials.

1.4. **Innovative dust collector**

The fluidized bed spray dryer granulator is equipped with a return powder device, which can effectively recover unformed powder or fine particles during the production process, further improving the utilization rate of materials, reducing waste, and improving the uniformity and quality of the finished granule.

1.5. **Improved Design of Internal Mixing Multi-Fluid Atomizer**

The fluidized bed spray dryer granulation machine's misting system employs an improved design of an internal mix multi-fluid misting nozzle that can handle materials with a specific gravity of up to 1.3 g/cm3. This design is particularly suitable for handling high concentration liquid materials and ensures efficient spray drying and granulation even under conditions of high specific gravity materials.

1.6. **Optimized drying chamber and collection chamber design**

The structure of the spray drying chamber, collecting chamber, fluidized bed, and secondary air supply system in the fluidized bed spray granulation machine has been optimized to better meet the requirements of spray drying. The goal of this design is to achieve more uniform drying effects and reduce energy consumption, thereby improving the stability and reliability of production.

2. PGL Series Fluidized Bed Spray Drying Granulation Machine - Equipment Composition

2.1. **Spray Drying Chamber**

As the core area for material drying, the spray drying chamber converts liquid material into mist particles through a high-speed atomization system, and then the water is rapidly evaporated under the action of hot air to form dry particles. The design of the drying chamber optimizes the airflow distribution to ensure that the material is evenly dispersed and fully dried.

2.2. **Capture Chamber**

The main function of the collection chamber is to collect small particles or fine powders that are not fully dried during the drying process and return them through the recycling system for drying or granulation. Such a design not only reduces material waste but also improves product yield and quality.

2.3. **Fluidized Bed**

A fluidized bed is an essential component for achieving fluidization of materials. After spray drying, the granular material is further dried and cooled by air flow in the fluidized bed. The design of the fluidized bed optimizes the contact area between air flow and the particles, allowing the material to be dried thoroughly and forming uniform particles.

2.4. **Secondary Air Supply System**

The secondary air supply system is an important component in ensuring the efficiency of the entire equipment. Through the secondary air supply system, hot air can be distributed more evenly throughout the various parts of the equipment, ensuring that the material is always in the best state during the drying and granulation process.

2.5. **Returning Powder Device**

The return powder device can effectively collect the fine powder that has not fully formed into particles during the drying process and return it to the system for particle formation. This not only reduces waste, but also improves the overall particle formation effect and product quality.

3. PGL Series Fluidized Bed Spray Drying Granulator - Application Range

The widespread use of the PGL series fluidized bed spray dryer granulator is due to its efficient and reliable features, suitable for production needs in various industries:

3.1. **Pharmaceutical Industry**
