Answer:
The SF&DS Sterideal is a tubular heat exchanger with a concentric two, three or multiple tubular assembly system. A distinguishable feature of this system is that the tubes have been spirally wound. Such features as a continuous tube without sharp edges and weld seams reduce the chance of product accumulation and contamination to a minimum. This therefore guarantees maximum durability. Such a system can also be cleaned quicker and more efficiently. In the Sterideal the product can be rapidly heated to a high temperature (ca. 130 °C). That means a minimum loss of flavour with a very effective heat treatment. The Sterideal has been designed in such a way that, when cooling the product, a large share of the heat (over 86%) may be recovered.
