The powder flow heat exchanger, also referred to as a solid particle heat exchanger or solid particle thermal exchanger, is far more than a simple hardware assembly. It represents a new approach to powder heat transfer by integrating dense-phase flow theory, advanced heat transfer plate technology, and specialized powder heat transfer modeling software into a highly integrated system.
A conventional powder flow heat exchanger is typically composed of four key components: a feeding hopper, a heat transfer plate module, a discharge unit, and an automatic control system.In cooling applications, the cooling medium is typically chilled water supplied by a cooling tower system or a closed-loop chiller system. In heating applications, hot water, steam, or thermal oil is commonly used as the heating medium.

Solid particles move slowly downward under gravity through a series of hollow heat transfer plates. The heat transfer fluid flows in the opposite direction through the internal channels of the plates, transferring heat through the metal plate walls to or from the external particles, thereby achieving efficient cooling or heating of the material.

Features
·The slow and precisely controlled product flow rate helps prevent particle agglomeration, wear, and material degradation.
·The heat transfer plates provide indirect cooling or heating without direct contact with the product, eliminating the risks of moisture variation and bacterial contamination.

·Dense-phase conveying technology ensures consistent particle flow and uniform, stable discharge temperatures.
·The vertical modular design minimizes the installation footprint and allows easy replacement or expansion of heat transfer plate modules, making it ideal for plant retrofits and production capacity upgrades.

·The system has no moving parts, resulting in reduced maintenance requirements and lower operating costs.
·The system requires no air cooling, eliminating the need for energy-intensive air handling equipment and preventing waste generation and dust emissions.

·Compared with conventional rotary drum coolers and fluidized bed coolers, the system can reduce energy consumption by up to 90%.
