Abstract: The present invention relates to a process for the production of a bacterially enriched animal feed composition. The process comprises the steps of a) providing a proteinaceous feed material to be fermented; b) providing an inoculum comprising bacteria, and wherein the concentration of bacteria in the inoculum of step b) is sufficient to outgrow any bacteria, yeast or moulds present in the proteinaceous feed material of step a); c) combining the materials of steps a) and b) and fermenting the proteinaceous feed material of step a) using the inoculums of step b), thereby providing a fermented proteinaceous feed material; and d) adding methanotrophic bacteria to the fermented proteinaceous feed material to provide a bacterially enriched animal feed composition.

Abstract: A fermenter and a method of fermentation in a U-shape and/or nozzle U-loop fermenter (100) comprising a U-part having an essentially vertical down-flow part (101), an essentially vertical up-flow part (102) and a substantially horizontal connecting part (103), which connects the lower ends of the down-flow part (101) and the up-flow part (102), a top part (104) which is provided above the U-part and has a diameter which is substantially larger than the diameter of the U-part, means for creating liquid circulation in U-part of the fermenter, and one or more gas injection points (110) for the introduction and dispersion of the gas(ses) into the fermentation liquid. The pressure may be controlled differently in certain zones of the fermenter by pressure controlling devices (105, 106, 108) e.g.

Abstract: A U-shape and/or nozzle-U-loop fermentor has a U-part consisting of an essentially vertical downstream part (2), an essentially vertical upstream part (4), a U-shape bend part (3) which connects the lower ends of the downstream and upstream parts, an inline pump (12) placed in the U-part for circulation of fermentation liquid in the fermentor, a top part (5) which is placed above the upper end of the downstream part, gas supply members (7, 8, 9, 10) which are provided in the U-part with appending static-mechanical mixing members (13, 14, 15, 16, 17) for the comminution of the gases introduced into the fermentation liquid, and supply numbers for water and nutrient salts (18) and (19), respectively, and in connection with the supply members (7, 8, 9, 10, 18, 19) or in by-pass arrangements in connection therewith one (or more) ion sensor(s) or analyser(s) (20, 21, 22, 23) for sensing the concentration of at least one of the ion species phosphate, ammonium, nitrate and hydrogen ion, oxygen sensor(s) for sensing t

Abstract: A sensor for the measurement of moisture in a flow of material, especially loose material such as meal material, grains, granulates and similar materials which are to be pressed to form feed pills in presses. The sensor comprises a tube piece of an electrically conductive material with circular cross-section, and an elongated pole which is of circular cross-section and is disposed with its longitudinal axis concentrically and electrically insulated in the tube piece, and which consists of an electrically conductive material. When the moist material flows between the inside surface of the tube piece and the outer side of the pole, the sensor works with the moist material's conductivity as a condenser for the capacitive detection of the moistness, which can be determined on the basis of the detection.
