Refroidisseurs à lit fluidisé conventionnels

Carrier’s conventional, or static, fluid bed coolers are well suited for:

Multi-functional processing, providing drying, cooling, classifying, sterilizing, and more in a single unit

Continuous operation or batch processing

Efficient processing without product degradation – Carrier fluid bed coolers provide gentle fluidizing action

Refroidisseurs à lit fluidisé conventionnels

Carrier’s conventional (static) fluid beds cool a variety of products without the aid of vibration. These fluid bed coolers pass air directly through a bed of solid material via a perforated plate, nozzles, or other fluidizing media, thereby lifting and mixing the solids. At a certain air velocity (the fluidization velocity), the bed will behave much like a boiling liquid.

Applications

Fly Ash

Provides controlled cooling of hot fly ash through direct contact with fluidizing air. Uniform bed conditions maximize heat transfer while preparing material for storage, handling, or downstream processing.

Fertilizers & Chemicals

Cools fertilizer granules and chemical products with controlled airflow and residence time. Uniform fluidization minimizes temperature variation while maintaining product integrity and consistent downstream handling characteristics.

Food, Dairy, Sugars & Fruit

Provides gentle, uniform cooling of heat-sensitive food products using precisely controlled fluidizing air. Consistent bed temperatures help protect product quality while achieving required discharge temperatures.

Pet Food & Animal Feed

Uniformly cools pellets, granules, and feed products after thermal processing. Controlled airflow removes residual heat while maintaining product integrity and preparing material for storage or packaging.

Minerals, Ores & Pigments

Efficiently cools hot mineral products through controlled fluidization and convective heat transfer. Uniform material distribution provides consistent discharge temperatures while supporting continuous downstream processing.

Caoutchouc

Provides controlled cooling of rubber particles and crumb rubber following thermal processing. Fluidizing air and uniform bed movement efficiently remove heat while minimizing agglomeration and maintaining material flowability.

Produits pharmaceutiques

Delivers precise cooling of pharmaceutical powders and granules using controlled airflow and residence time. Uniform fluidization supports repeatable discharge temperatures while maintaining product quality and process consistency.

Plastiques

Cools plastic pellets, fabricated products such as ABS, polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), PET, and SBS, and granules through uniform air-to-product contact. Controlled fluidization efficiently removes process heat while minimizing material degradation and preparing products for handling, storage, or packaging.

Polymers & Resins

Provides uniform cooling of polymer and resin pellets using controlled fluidizing airflow. Efficient heat transfer achieves consistent discharge temperatures while maintaining particle integrity and reliable downstream handling.

Soda Ash

Conventional Fluid Bed Coolers FAQs

What is the main difference between conventional and vibrating fluid bed coolers?

Conventional fluid bed coolers rely on airflow alone to fluidize and cool material, while vibrating equipment adds mechanical vibration to improve handling of more difficult materials.

What types of materials are best suited for conventional fluid bed cooling?

They work best with materials that fluidize easily and do not require additional agitation, making them ideal for consistent, free-flowing products.

Can conventional fluid bed coolers handle both batch and continuous processes?

Yes. These equipment are adaptable to both batch and continuous operation depending on production needs.

How are temperature and residence time controlled?

Operators can adjust airflow, bed depth, and retention time to precisely control product temperature and cooling performance.

Are conventional coolers energy efficient?

Yes. Efficient heat transfer and simple design help reduce energy consumption while maintaining consistent product cooling.
