Abstract

The invention relates to a device for heating, with steam at reduced pressure, directly or indirectly, a material or product which it is desired to subject to a thermal treatment, which includes a heat-exchange chamber which is supplied with water vapour via a pressure-reduction valve and discharged via an ejector device which is able to control the heating temperature of the heat-exchange chamber controlling the operating fluid of the ejector device. The device may be used as a safety device and advantageously applies to the chemical and food industries. Figure 1. <IMAGE>
