Abstract
A product is continuously processed by passing it upwardly through a vertical heat exchange cylinder while continuously scraping the inner surface of the cylinder free of any product which may adhere thereto. This cylinder is surrounded by upper and lower outer cylinders to form upper and lower annular spaces through which respective heat exchange media are circulated, whereby the product can first be heated and then promptly cooled while passing through the heat exchange cylinder. To allow for different rates of expansion and contraction of the cylinders, a double expansion joint is provided between the two outer cylinders; and a temperature sensing device protrudes through this joint and into the heat exchange cylinder to measure the temperature of the product as it passes from the heating section to the cooling section of the heat exchange cylinder.
