The invention relates to a process for heating pulps between two heating surfaces. It is mainly characterised by the differential speed of the heating surfaces being in the region of -5m/s and +12 m/s where it is an advantage if the differential speed is virtually zero. The invention also relates to a device for implementing the process. In this device, rolls (2, 3, 2', 3', 10, 11, 12) are provided as heating elements according to the invention. The surface design has the surface structure selected.
