Publication number: 20220378057Abstract: 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.Type: ApplicationFiled: July 10, 2020Publication date: December 1, 2022Inventors: Dennis Glinke, Ulrich Rolle, Jurgen Gehling, Ludger Tacke, Hubert Assing

Patent number: 11191284Abstract: 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.Type: GrantFiled: April 12, 2018Date of Patent: December 7, 2021Assignee: GEA TDS GmbHInventors: Uwe Schwenzow, Ludger Tacke, Hubert Assing, Helmut Buss, Ludger Leiwering

Patent number: 11191283Abstract: 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.Type: GrantFiled: July 10, 2017Date of Patent: December 7, 2021Assignee: GEA TDS GmbHInventors: Hubert Assing, Helmut Buss, Uwe Schwenzow, Roland Stange, Ludger Tacke, Dietrich Zimmermann

Publication number: 20190329148Abstract: 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.Type: ApplicationFiled: June 14, 2017Publication date: October 31, 2019Applicant: GEA TDS GmbHInventors: Uwe Schwenzow, Ulrich Rolle, Hubert Assing, Ludger Tacke, Andreas Schmied

Publication number: 20190327988Abstract: 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.Type: ApplicationFiled: June 14, 2017Publication date: October 31, 2019Applicant: GEA TDS GmbHInventors: Uwe Schwenzow, Ulrich Rolle, Hubert Assing, Ludger Tacke, Andreas Schmied

Publication number: 20190191729Abstract: A method for aseptic heating of a liquid product in a heat exchanger unit in a UHT system is described. The heat exchanger unit is a tubular heat exchanger, in which an indirect heat exchange on a wall takes place between the liquid product and a heating medium by a single heating medium flow with a heating medium inlet temperature flowing in a heat-releasing heating medium chamber between a heating medium inlet and outlet of the heat exchanger unit running countercurrent to a flowing single product flow guided in a heat-absorbing product chamber between a product input and output of the heat exchanger unit. A total heat exchanger path is formed between the product input and output, in which the product flow is heated from a product input temperature to a product output temperature. At least the product output temperature and the heating medium inlet temperature are monitored and regulated.Type: ApplicationFiled: August 16, 2017Publication date: June 27, 2019Inventors: Uwe Schwenzow, Erwin Süthold, Wolfgang Schlösser, Franz Tasler, Hubert Assing, Reinhold Dreckmann

Apparatus for influencing the outflow region of a tube carrier plate of a tube bundle heat exchanger
Patent number: 9709345Abstract: 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.Type: GrantFiled: May 30, 2014Date of Patent: July 18, 2017Assignee: GEA TDS GmbHInventors: Ulrich Rolle, Günter Lütkebruns, Uwe Schwenzow, Hubert Assing, Markus Grimm, Ralf Speemann -
