<p>The invention relates to an apparatus for treating a fluid product by injecting steam from a steam inlet (11) and the fluid product from a product inlet (12) into a mixing chamber. Said mixing chamber (13) comprising an outlet for the treated product (14), a steam injection opening (15) with a first valve member (17) disposed in said steam injection opening, a product injection opening (16) with a second valve member (18) disposed in said product injection opening (16). The position of said valve members (17,18) determining the width of a substantially annular discharge orifice around each valve member, said discharge orifices facing one another. The apparatus further comprises pressure sensitive displacement means (19,20) to permit movement of the second valve member (18) in response to the pressure in the product inlet (12). The invention also relates to a method for treating a fluid product. <IMAGE></p> |
