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 method for heating a concentrate in an installation for spray drying comprises increasing a pressure of the concentrate from a low pressure level at a flow temperature to a high pressure level. The concentrate is heated at a high pressure level to a spraying temperature using a high-pressure heat exchanger. The concentrate is shear loaded using a shearing device and immediately transferring the concentrate to a location of pressurized spraying, wherein a transfer time for the immediate transfer is determined by a fluidic effective distance between the shearing device and the location of the pressurized spraying.

Abstract: A device for heating a concentrate comprises a drying tower comprises a plurality of pressurized spray nozzles, a feed tank fluidly connected with an inlet of a low-pressure heat, a feed pump, and a high-pressure piston pump connected on an inlet side with the outlet of the low-pressure heat exchanger. A first high-pressure line section of the high-pressure line is configured to connect the outlet of the high-pressure piston pump with the inlet of the additional high-pressure heat exchanger. A second high-pressure line section of the high-pressure line is configured to connect the outlet of the additional high-pressure heat exchanger with the pressurized spray nozzles. A means for defined shear loading of the concentrate is located in an outlet-side channel and comprises an annular-shaped space.

Abstract: The invention relates to a UHT system for heat treating temperature-sensitive food products, in particular desserts or dessert-like products, comprising a pre-heating zone and a subsequent high-heating zone. The aim of the invention is to achieve accurate and fast temperature adjustment of the food product leaving the pre-heating zone to the temperature conditions at the inlet of the high-heating zone in a UHT system of the generic type, and at the same time, with an equal dwell time for all partial amounts of the food product, to ensure that the food product is treated in a particularly thermally gentle manner and to keep the mechanical loading of the food product as low as possible.
