DEVICE FOR CONTINUOUS THERMAL PASTEURISATION OF PRODUCTS IN THE FORM OF DIVIDED SOLIDS

摘要

The invention relates to a device for the continuous thermal pasteurisation of products in the form of divided solids, said device comprising a closed housing (13) into which the products are fed. Said housing contains controlled means consisting of heating contact walls (18) acting directly on the products as they are fed into the housing. According to the invention, the closed housing (13) is connected to a source (60, 62, 30) for supplying wet steam at atmospheric pressure, said steam being overheated, before entering the housing (13), by an element (62) for reheating gaseous fluids arranged outside the housing. The temperature control of said element is related to the temperature control of the contact walls (18) in such a way that the temperature (Tv) of the overheated wet steam at atmospheric pressure in the closed housing (13) is essentially equal to the temperature (Ts) of the contact walls.
