ABSTRACT:
When maintaining a flow of a mixture of products consisting of a liquid of low to medium viscosity incorporating solid particles at a certain temperature and for a certain period of time the mixture remains for some time in a vessel of a substantially cylindrical shape. The residence time in the vessel of the solid particles mixed with the liquid is controlled separately from the liquid in that the solid particles are carried through the vessel at a regulable speed, independently of the speed of flow of the liquid through the vessel, with the aid of a rotatable conveyor means which is permeable to liquid but not to the solid particles and whose axis of rotation coincides with the axis of the vessel. The solid particles remain mixed with the liquid. The residence time of the solid particles is regulated such that the core of the solid particles attains the same temperature as the liquid, without the liquid remaining for too long a time at the desired end temperature.
