2. Что такое Scraped Surface Heat Exchanger 

A теплообменник со скребковой поверхностью has rotating blades in a cylindrical heat transfer surface. These blades scrape the inner wall continuously. As a result, they remove the fouling layers and increase heat transfer. In contrast to the static exchanger, this design can work with high-viscosity and non-Newtonian fluids.

3. Why Scraping Technology Matters

The scraping technology avoids product buildup. First, it minimizes thermal resistance. Next, it increases temperature uniformity. In addition, it prevents product degradation. For these reasons, manufacturers enjoy high product quality and process stability.

4. Working Principle of an Scraped Surface Heat Exchanger

Initially, the product is poured into the cylindrical barrel. Subsequently, a rotating shaft actuates the scraping blades. Following this, the blades continuously remove the product from the heat transfer surface. In the meantime, the heating or cooling media flows outside the barrel. Therefore, efficient heat transfer takes place during the process.

5. Basic Structure

  • Heat Transfer Cylinder

The barrel presents a smooth surface on the inner side for effective scraping.

  • Rotating Shaft

The shaft actuates the blades at a controlled speed.

  • Scraper Blades

The blades remain in constant contact with the heat transfer surface.

  • Drive Unit

The drive unit allows the control of torque and rotation speed.

  • Sealing System

Seals prevent leakage and provide hygienic operation.

All components collectively support stable continuous processing.
