ABSTRACT
The scrapers in scraped surface heat exchanger (SSHE) continuously scrape the product off the surface, thus eliminate fouling, increase turbulence, aid in controlling product residence time, mix the product, avoid localized treatment and also facilitate the cleaning operation. These features have greatly increased the applications of SSHE for manufacturing dairy products especially traditional dairy products (TDP) over last three decades. SSHE has also been used for the manufacture of several western dairy products. The SSHE has been employed for many processing milk into many dairy products majority of which are the indigenous milk products of India. The inherent features of SSHE make it suitable to handle the products with high viscosity and particulate structure, which occurs in most of the dairy product especially in traditional Indian dairy products (TIDP). Therefore, the SSHEs have replaced many kettle based units that were used in the manufacture of dairy products.
