A device for killing microorganisms in a fluid flow of products, comprising a duct means (11) made of a flexible material for conveying a flow of products heated to a predetermined temperature and a delimiting means (5). The delimiting means (5) comprises pressing means (9) for delimiting non-intercommunicating subvolumes (dV) of the duct means (11) and for transporting through the duct means (11) a subquantity of the flow of products contained in each subvolume (dV). The pressing means (9) are adapted, alternately and in a starting position along the duct means (11), to engage with the duct means (11) for compression thereof. The pressing means are also adapted to move along a portion of the duct means (11) while maintaining said engagement. Two succeeding pressing means (9) thus delimits between them a subvolume (dV) that does not communicate with the rest of the volume of the duct means (dV). The invention also concerns use of such a device as well as a method for killing microorganisms in a fluid flow of products. |
