Abstract: A method for treating liquid food products after direct heating comprises a first cooling of the liquid food product occurring on a floor of the infuser vessel up to an outlet opening. A second cooling of the liquid food product occurs in a tubular section connecting directly to the outlet opening. A third cooling of the liquid food product occurs in a housing cover of a pump housing of a centrifugal pump. At least one flushing operation of the pump housing and of an impeller via a rear impeller gap is performed, wherein the at least flushing operation occurs via a front impeller gap located between the housing cover and the impeller. Volume flows of the at least one flushing operation are greater than equalization flows within the pump housing.

Abstract: A manifold with a circular cross-section having a deviation angle of 180 degrees for a tube bundle heat exchanger for large product pressures has a first and second flange on each inlet and outlet. The manifold has two manifold halves respectively made of a single piece, and each half comprises a joining point on an end facing away from a flange. The manifold halves are connected together on the associated joining point. Extension of the passage cross-section of each manifold half is formed by rotationally symmetrical through openings, from which at least one of the flanges and at least one of the joining points extends in the respective coaxial arrangement on rotational axes. First and second axes of through openings of the first manifold halves and third and fourth axes of through openings of the second manifold halves extend on a common plane representing a meridian plane for each flange.
