Abstract
An apparatus for treating a fluid product by injecting steam from a steam inlet and fluid product from a product inlet into a mixing chamber. The mixing chamber includes an outlet for the treated product, a steam injection opening with a first valve member disposed therein and a product injection opening with a second valve member disposed therein. The position of the first and second valve members determines the width of a substantially annular discharge orifice around each valve member. The discharge orifices face one another. The apparatus additionally includes pressure sensitive displacement means which permits movement of the second valve member in response to the pressure in the product inlet. The invention additionally relates to a method for treating a fluid product utilizing the apparatus as described above.
