Abstract: Controlling and/or treating heat-sensitive liquid food products ensures improved control of a filling level in an infuser container. Therefore, a constant dwell time of the product to be heated is reached in the event of product-fouling in the centrifugal pump. The pump is designed such that one part of a volume flow of the product, transported by an impeller wheel, regularly rinses the impeller wheel and the areas of a pump chamber that are directly adjacent to the impeller wheel. A reduction in the volume flow of the centrifugal pump is then counteracted by increasing the initial rotational speed if the reduction is simultaneously associated with a drop in temperature of the product. The increase of the initial rotational speed is carried according to the drop in temperature of the product and/or an increase in the temperature of the steam to constantly maintain at least the temperature of the product.

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 metering device with a product conduit section, through which a base product forcibly flows, with at least one storage container for an additive, which is connected with an associated metering point respectively via a removal conduit, which is arranged on or respectively in the product conduit section, with a mechanism for forcibly conveying the additive, with quantity-based capturing of the base product and of the additive, with sterile steam and with a control device assigned to the metering device. The metering point is provided within a metering valve, which forms a product chamber, into which the product conduit section opens and from which it exits, an initial chamber and a partial chamber as well as a receiver of an end section and of a terminal side.

Abstract: A method for the aseptic measured delivery of a liquid additive (Z) into a forced flow of a base product (P), wherein the additive (Z) is removed from a storage container (18) under aseptic conditions by means of a removal conduit (18a) and is fed via an end section (E) of the removal conduit (18a) to the base product (P), which flows through a product chamber (RP) and a metering device and valve.
