摘要:
The invention relates to a method for the treatment of a product in the form of particulate solids, comprising the steps of: introducing the product into a chamber (1) with a pressurised ozone atmosphere; conveying the product through the chamber in a continuous movement such that the product is continuously in the ozone atmosphere as it is being conveyed through the chamber, the product being conveyed through the chamber by vibration means (3, 6) which vibrate the chamber; and ejecting the product from the chamber through the chamber outlet (7) after it has passed once through the chamber.

The invention relates to a device for the heat treatment of a product, comprising an enclosure, means for transporting the product between an inlet of the enclosure and an outlet of the enclosure, which comprise a screw (10) mounted in such a way as to rotate in the enclosure according to a geometric rotational axis (X) and means for rotatably driving the screw, and means for heating the screw by Joule effect. According to the invention, the screw has an electrical resistance that varies along the geometric rotational axis.

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 (T v ) of the overheated wet steam at atmospheric pressure in the closed housing (13) is essentially equal to the temperature (T s ) of the contact walls.
