Abstract
The disclosure relates to an improvement in a shell-and-tube heat exchanger particularly intended for products containing fibres (11) or particles. The improvement comprises a product flow insert (5) consisting of a number of heat transfer tubes (3) with a baffle plate (6) fixedly secured in each end (13) of these transfer tubes (3). En order for fibres (11) and particles to pass the baffle plates (6) without undesirably accumulating, at least that one of the baffle plates (6) which is turned to face towards the direction of flow of the product is designed with flow distributors (12) which wholly or partly surround the tube ends (13) of the heat transfer tubes (3).
