Fluid Bed Cooler for DDGS Dryer

Katalyzer Engineering Systems Pvt. Ltd. successfully designed and manufactured a Fluid Bed Cooler for Distillers Dried Grains with Solubles (DDGS), ensuring efficient cooling before packaging. This system plays a crucial role in moisture control and temperature reduction, preventing packaging issues and preserving product quality.

Project Highlights:

Material Processed: DDGS powder from a rotary tube bundle dryer
Cooling Technology: Fluid Bed Cooler for uniform temperature reduction
Temperature Control: Incoming: ~100°C → Outgoing: 35-40°C (ambient)
Air Handling System: Forced Draft & Induced Draft Blowers
De-dusting System: Integrated for fine particle control
Material Handling: Complete inlet and outlet system designed in-house

Process Overview:

DDGS powder exits the rotary tube bundle dryer at high temperatures (~100°C) and enters the Fluid Bed Cooler, where controlled air circulation cools the material efficiently. The system ensures:

Moisture-free cooling to prevent clumping during packaging
Optimized air distribution for uniform cooling
Effective de-dusting to maintain product purity

Extensive trials were conducted at our pilot plant facility to analyze particle size, bulk density, and flow characteristics, enabling a custom-engineered solution tailored to the client’s needs. The fluid bed cooler is now operating as per the design parameters, delivering a consistent and reliable cooling process for DDGS production.
