Abstract: Directly heating a protein-enriched milk product occurs by introducing steam, the direct heating taking the form of an infusion or injection method. The described technique significantly extends service time, ensuring a content of non-denatured whey proteins in the treated protein-enriched milk product greater than that obtained in the prior art. The milk product, which is preheated and kept at temperature is indirectly cooled before direct heating by a recuperative cooling step from the preheating temperature to a cool-down temperature with a temperature difference ranging from 5 K to 10 K. The direct heating from the cool-down temperature to the high pasteurization temperature is controlled by direct heating setting parameters which are known per se. Finally, the milk product is cooled by flash cooling from the high pasteurization temperature to a necessarily required exit temperature.

Abstract: The industrial production of an extract by means of solid-liquid extraction improves the exchange of substances during extraction and allows enhanced dehumidification of a raffinate with residual moisture. The extraction is enhanced during a first dwell time by at least partially flooding a vessel in the form of at least one flow discharged with a secondary solvent or the obtained extract, swirling and keeping in suspension the primary mixture within the vessel by supplying the secondary solvent or the obtained extract via a foot area of the vessel, and/or moving the vessel relative to the extraction container within the obtained extract. The secondary solvent or the extract circulates in the extraction container by a circulation guide incorporating the extraction container from top to bottom relative to the extraction container, and the extract freed from raffinate with residual moisture obtained by dehumidification is supplied to the separated or to be separated extract.

Abstract: Controlling the production of an extract using solid-liquid extraction that improves the exchange of material during the extraction process and allows a controlled dehumidification of a raffinate with residual moisture in order to obtain additional valuable extract is described. The steps include providing a first mass in an extraction container, supplying a second mass to the first mass without spatial constraints and distributing and mixing the second mass into and with the first mass, discharging a mixture of the extract and the raffinate from the extraction container, separating the discharged mixture into the raffinate with residual moisture and extracts released from the raffinate with residual moisture, and further treating the raffinate with residual moisture at least such that the residual moisture consisting of the extract is at least partly removed from the raffinate with residual moisture by dehumidification and is supplied to the already separated extract.

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: 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.

Abstract: 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 more particularly for temperature-sensitive and/or viscous food products in the dairy industry, for example desserts, sauces or concentrates, is described. The apparatus operates so that the tendency for deposits to form in the region of the tube carrier plate through which product flows out is reduced. An annular space-like outlet channel has, at least overall in the region thereof between a maximum outside diameter of an outlet-side displacement body and a second connection opening, a channel passage cross-section, which has a constant cross-section over the entire length of the region and which corresponds to a total cross-section of all of the inner tubes through which a product flows in parallel, which inner tubes each have an individual cross-section.
