Apparatus for use in heating and mixing flowable food products or other flowable substances comprises at least one steam injector for injecting or introducing steam into the food product. In the case of an apparatus including a single such steam injector, a duct 6,10 extends between an inlet 8 and an outlet 9. A plenum chamber 12 is disposed adjacent the duct and an inlet 14 is provided for admitting steam to the plenum chamber. An orifice 35 opens from the plenum chamber into the duct and, by virtue of a Coanda surface located in the duct, steam is induced to flow towards the outlet and entrain the food product with it. A downstream end portion 10 of the duct may be outwardly flared or frustoÂconical shape and constitutes an expansion chamber in which steam collapses and substantially all of its energy is imparted to the food product.. A plurality of parallel steam injectors may be provided to enhance performance. |
