Abstract: The invention is directed to a method of preparing a blend comprising a polysaccharide and a water soluble or dispersible ingredient. More in particular, the invention relates to the preparation of such blend using a filter centrifuge. The method of the invention comprises a. feeding a polysaccharide slurry to a filter centrifuge via a first inlet; b. rotating the filter centrifuge at a first centrifuge speed to provide a polysaccharide cake; c. feeding a sprayable ingredient to the filter centrifuge via a second inlet; and d. spraying the sprayable ingredient onto the polysaccharide cake while rotating the filter centrifuge at a second centrifuge speed to produce a blend of the polysaccharide and the ingredient.

Abstract: An apparatus for candling eggs includes a transmission system of a luminous flux directed towards the egg to be examined and located in its incubation rack a reception device of the luminous flux transmitted after passing through the mass of the egg, and an automatic analyzer of the recorded signals. The transmission system and the reception device are arranged in a vertical plane or a substantially vertical plane, one beneath the eggs to be examined and the other above the latter. A screen protects the transmission system against smears originating from the eggs in the incubation racks.
