  • Patent number: 12115712
    Abstract: A single screw extruder (E) for the extrusion of food or feed, comprising in the direction of flow of a product to be extruded: i) a processing section (8); ii) a bypass outlet (B); iii) a valve plate (V); iv) a die plate (D); and iv) a cutter (6). The flow of product can be directed through the valve plate, under normal operating conditions of the extruder (E), and through the bypass outlet (B), during start-up of the extruder (E) or for maintenance purposes, downstream of the valve plate (V). The valve plate (V) is arranged on or in a mounting plate (M). The cutter (6) and the mounting plate (M) are provided with interacting guiding mechanism that prevent rotation of the cutter (6), vis-à-vis the mounting plate (M); and the cutter (6) and the mounting plate (M) are mechanically fastened to each other with rotational locking mechanism.

  • Publication number: 20240319217
    Abstract: A sample carrier includes a bottom, at least one side wall, and a contact face for receiving a sample. The side wall extends upward relative to the bottom. A circumferential rim is provided on the contact face. The sample carrier can be used in a sample handling system which includes a counterpart support element and a sample storage for receiving the sample carrier. Multiple sample storages are combined to sample storage rails with can be arranged on a sample storage shelf. The sample carrier can be part of a system for performing thermomechanical analysis, including the sample handling system while the samples, arranged in the sample carriers, are stored in the sample storages of the sample storage rails arranged in the sample storage shelves from where they are transported to the sample support with the help of the counterpart support element.

  • Publication number: 20100233321
    Abstract: A process produces a feed composition for cattle or the like, in particular a fattening feed, wherein conventional feed is intended to be replaced. First a premix (1) of cereal components, fat, molasses, vitamins, minerals and/or other ingredients is mixed and conditioned with addition of steam (7) and water (6) and subsequently fed to a mechanical and/or thermal treatment where the mixture is heated, processed and shaped to form porous lumps.

  • Publication number: 20080286428
    Abstract: A method for producing feedstuff, in particular pelletized feedstuff for chicken and pigs includes thermally holding pellets at a pellet press output and in post-conditioning said pellets in a rear container (6). Afterwards, the pellets come from the rear container (6) to a mixer (7), wherein liquids can be added without cooling. Drying and cooling are carried out afterwards, the pellets being transferred to a crumbler.
