The invention relates to an apparatus for influencing the outflow region of a tube carrier plate of a tube bundle heat exchanger, in particular for the food and beverage industry, and in this case in particular for temperature-sensitive and/or viscous food products in the dairy industry, for example desserts, sauces or concentrates, according to the preamble of claim 1. The object of the present invention is to develop an apparatus of the generic type in such a way that the tendency for deposits to form in the region of the tube carrier plate through which a product has flowed out is considerably reduced. This is achieved in that the annular space-like outlet channel (600d) has, at least overall in the region thereof between a maximum outside diameter (dmax) of the outlet-side displacement body (12) and the second connection opening (600a), a channel passage cross section (As) which has a constant passage cross section over the entire length of the defined region and which, in this region, corresponds to a total passage cross section (NAi) of all of the inner tubes (300), through which a product flows in parallel, of the number (N), which inner tubes each have an individual passage cross section (Ai) (figure 2).La invención se refiere a un dispositivo para influir en la región de descarga de una placa de soporte de tubos de un cambiador de calor de haz de tubos, en particular para la industria de alimentos y bebidas, y en este caso en particular para productos alimenticios sensibles a la temperatura y/o viscosos en la industria de los lácteos, por ejemplo postres, salsas o concentrados, de acuerdo al preámbulo de la reivindicación 1. El objeto de la presente invención es el de desarrollar un dispositivo del tipo genérico de manera que se reduce considerablemente la tendencia a la formación de depósitos en la región de la placa de soporte de tubos a través de la cual se descargó un producto. Esto se logra al hacer que el canal con forma de espacio anular del lado de
