Industrial Scraped Surface Heat Exchanger System

Product Description

Wuxi Yiteng Pressure Vessel Co., Ltd. manufactures customized Industrial Scraped Surface Heat Exchanger Systems designed for processing high viscosity, sticky and heat-sensitive materials.

Traditional heat exchangers often face problems such as:

• Material sticking on heating surfaces
• Reduced heat transfer efficiency
• Product burning or degradation
• Difficult cleaning

The scraped surface heat exchanger solves these challenges through a continuously rotating scraping mechanism.

Working Principle

The product flows through the annular heat transfer area.

During operation:

1. Material enters the heat exchanger cylinder
2. Rotating scraper continuously removes product from the wall
3. Fresh material contacts the heating/cooling surface
4. Heat transfer efficiency remains stable
5. Product exits with controlled temperature

The scraping action prevents fouling and improves thermal performance.
