A plant for heat treating heat-sensitive fluid foodstuffs an infusion chamber in which the fluid foodstuff is subjected to a heat treatment by a feeding of steam, and a fluid foodstuff inlet connected to a plurality of openings at the top of the infusion chamber for creating a plurality of essentially downwardly directed separate fluid foodstuff jets. The infusion chamber has a bottom section configured to collect the fluid foodstuff from the jets. The bottom section has an outlet opening at the bottom of the infusion chamber for allowing the collected fluid foodstuff to exit the infusion chamber. The outlet opening is seamlessly connected to the inlet of a pump. A cooling jacket surrounds the bottom section for cooling the bottom section. The cooling jacket extends all the way down to the pump.

A method for removing deposits inside a section in a food processing system is provided. The method comprises introducing a cleaning liquid into the section, inducing boiling of the cleaning liquid by adjusting a pressure and/or a temperature inside the section to a first pressure value and/or a first temperature value, thereby forming bubbles in the cleaning liquid, imploding the bubbles by adjusting the pressure and/or temperature to a second pressure value and/or a second temperature value, thereby forming a mechanical impact on the deposits such that these are released from the section, and transferring the deposits being released by the cleaning liquid out from the section.

A method and device to treat liquid to reduce the amount of microorganisms in the liquid to a preselected level and/or to mitigate the growth of microorganisms are disclosed. Utilizing the method or device, liquid product is sprayed into a cavity of a reactor using a nozzle that produces a flat spray to provide means for efficient heating and treatment of the liquid.

An article includes a heating medium injector, a mixture flow path, and a vacuum chamber. The heating medium injector has a heating medium path connected to receive a heating medium such as steam and a product path connected to receive undenatured meat protein. The heating medium injector also includes a mixing structure and a mixture outlet. The mixing structure comprises a structure within the heating medium injector at which the heating medium path and product path merge and the mixture outlet is connected to receive material from the mixing structure. The mixture flow path defines a mixture flow path volume and is connected at one end to the mixture outlet of the heating medium injector and at the opposite end to the vacuum chamber. Undenatured meat protein is contained within the vacuum chamber outside of the mixture flow path volume.

The present invention relates to a method (200) for producing a heat-treated concentrated dairy product (cdp). The method (200) comprising the steps of passing (210) the dairy product (dp) under a pre-determined pressure through a reverse osmosis, RO, filter (110) at a first temperature, the pre-determined pressure being sufficient to allow reverse osmosis, thereby concentrating the dairy product (dp). Preheating (230) the concentrated dairy product (dp) at a second temperature for a second period of time to stabilize the concentrated dairy product (dp). Homogenizing (240) the stabilized concentrated dairy product (dp) to reduce a size of particles in the stabilized concentrated dairy product (dp). Heating (250) the stabilized concentrated dairy product (dp) at a third temperature for a third period of time to reduce microorganisms in the stabilized concentrated dairy product (dp), thereby forming the heat-treated concentrated dairy product (cdp).

The invention relates to an adjustable steam injector of the type which has an injector housing with an inlet for a product which is to be heated and an inlet for steam. The injector housing also has an outlet for the product mixed with steam. The injector also includes an injector body displaceable in the injector housing. About the front end of the injector body there are disposed concentric gaps for product and steam, respectively. The injector body has a recess in its front end. The recess has the same extent as the cross sectional surface of the injector body and has its greatest depth in the center of the injector body.
