ABSTRACT:
A scraping heat exchanger for continuously heating or cooling viscous or highly viscous substances, particularly shortenings, includes a product cylinder which is surrounded by the heat carrier medium and a rotatably driven shaft mounted in the product cylinder. Together with the product cylinder, the shaft forms an annular gap for receiving the substance to be treated. Elongated scraping blades are attached to the shaft, wherein each blade has a cutting edge at the leading side in the direction of rotation and fastening webs at the trailing side. The scraping blades have comb-like teeth in the space behind the edge and between the fastening webs.
