NORMIT Delta T Scraper heat exchanger for product knitting

 The unit is designed for heating or cooling various semi viscous and viscous products such as: meat, margarine, ice cream mix, heavy cream, cottage cheese, ketchups, yogurts.

  Device 

The scraper heat exchanger consists of two concentrically arranged pipes: the inner one is a working cylinder (shaft) with scrapers, and the outer one is a cylinder-shell. The product to be heat treated moves in the annular space between the outer and inner cylinders of the heat exchanger. Fluoroplastic scrapers are installed on the inner rotating shaft. The scrapers are pressed against the inner walls of the cylinder during rotation, stirring and significantly improving the heat exchange in the viscous product. As a result, the product in the working zone of the heat exchanger has a translational-rotational motion. The product is fed from the bottom to the top.
