Apparatuses for the high temperature thermal treatment of liquid foods, such as milk, in order to provide them with a long preservation span.

摘要

1. An installation intended for the high-temperature heat-treatment of liquid foodstuffs, in particular milk, with a view to ensuring their lengthy preservation, in which the liquid subjected to preheating before being introduced into the chamber where it is treated at high temperature by injection of steam, characterized in that the treatment chamber (6) includes at least one tube (7) into which the liquid flows naturally and which is heated by the steam, this tube being of a material such as polytetrafluoroethylene which is capable of avoiding the formation on the walls of the tube of a deposit even of little thickness from the liquid being treated.
