The purified and heated air is drawn in by a suction fan from the bottom, passing through the perforated mesh plate of the material hopper. Inside the working chamber, the combined effects of stirring and negative pressure create a fluidized state. Moisture rapidly evaporates and is carried away by the exhaust air, resulting in efficient drying of the material.

The wet material enters the drying chamber through the feed inlet. Under the action of vibration force, the material is fluidized and continuously conveyed forward along the horizontal fluidized bed. Hot air flows upward through the bed, exchanging heat with the wet material. The humid exhaust air is filtered by a cyclone separator, while the dried product is discharged from the discharge port.
This machine combined drying & cooling in one unit — ready for immediate packaging

Fluidized bed dryer, also known as fluidization drying, consists of air filter, heater, main fluidized bed chamber, cyclone separator, bag filter, high-pressure centrifugal fan, and control panel. Depending on the material properties, the dust collection system can be customized—either a cyclone separator, a bag filter, or both. For denser materials (e.g., granules and pellets), a cyclone separator suffices, while lighter powders require an additional bag filter. Optional feeding systems include pneumatic conveying or belt transport.

The solution, emulsion, suspension liquid or slurry are sprayed into fine beads in the hot air, going down from the top of the drying chamber to the bottom, the water will be evaporated to and the product becomes powder or granular product.

This equipment applies centrifugal spray drying technology specifically for herbal extract processing. It utilizes a high-speed centrifugal atomizer to disperse materials into fine droplets, ensuring full contact with hot air for instantaneous drying into powdered products.
This equipment adopts fully enclosed structure with all stainless-steel components. Triple air filtration system delivering 100,000-class clean air. Cooled wall jacket maintains wall temperature below 80°C. Integrated air broom system prevents wall accumulation. Zero product degradation – no charring, cross-contamination, or wall adhesion. High yield rate exceeding 95%

The solution, emulsion, suspension liquid or slurry are sprayed into fine beads in the hot air, Congealing Process Stages:
Pre-Cooling Stage
The molten material is cooled from the feeding temperature to its solidification point.
Solidification Stage
The liquid material completely solidifies. Temperature remains stable during this phase (near-isothermal conditions).
Cooling & Hardening Stage
The solidified product is further cooled to achieve final hardness.

"PENGDUO" considers that Fluidized Granulating is an organic combination of mechanical design and manufacture technology. Therefore hundreds of Granulating machines either for China or exported to USA, Japan, Indonesia, Iran and many other countries are designed in accordance with the process of raw materials.
We have manufactured decades specifications and 150 different machines to meet different needs. These practical experiences will be very beneficial to customers.

The powder raw material and adhesive in a cylinder are fully and fast mixed at the bottom to become a humid soft material. Then it is cut by high-speed cutter/wings and become uniform granules.

FLP Series Multi-Function Granulator & Coater is a new type of solid ingredients/ material preparation equipment, that integrates granulating, coating, fluidizing and rotating granulating together. It is mainly applicable for granulating, pill making and coating in pharmaceutical, chemical, foodstuff and so on industries, such as granules to be pressed to tablets, or to be filled into capsules, granules for other Chinese and Western Medicine, solid drinks, especially controlled release capsules and granules.

Integrated Spray Drying, Fluidization & Granulation System
This equipment integrates spraying, drying, fluidization, and granulation into a single-step process. The multi-fluid nozzle is particularly suitable for products with high polysaccharide content, strong viscosity, or thermoplastic properties.
Key structural improvements have been made to the spray drying chamber, collection chamber, fluidized bed, and secondary air supply system, ensuring optimal spray drying performance.

ZLB Extruder is primarily used in pharmaceutical, food, flavours, granule (instant drinks), chemical, and solid beverage industries to converts blended mixtures into uniform granules It is particularly suitable for high-adhesive materials.

BZJ Series Centrifugal Granulator & Coater

A new granulation equipment that utilizes the crystalline water in raw materials to directly convert powder into granules. It features a rational structure, stable and reliable performance, and is easy to clean and maintain. The produced granules can be used for tablet compression, instant granules, or capsule filling. It is mainly used in pharmaceutical, food, chemical, and other industries for granulation. Particularly suitable for materials that cannot be processed by wet granulation methods.

YK Swing Granulator is primarily designed for producing various particle sizes in pharmaceutical, chemical, and food industries. To process mixed materials into uniformly sized granules or breaks up lumpy materials into smaller particles. Effectively breaks down agglomerated dry materials.
