Device for heat exchange with a view to heating a product to a predetermined temperature

摘要

The invention relates to a device for heat exchange with a view to heating a product to a predetermined temperature. It is in particular characterised in that, instead of being introduced so as to move in countercurrent (counterflow) to the direction (13) of movement of the products to be treated, the transfer medium (11) is introduced into the channel in a region at least close to the region of introduction of the products and moves with them in the same direction. <IMAGE>
