FREMGANGSMÅDER OG UHT-ANLÆG TIL PRODUKTION AF EN DRIKKELIG BLANDNING FRA EN BÆREVÆSK OG MINDST ET KORNPRODUKT UNDER ASEPTISKE BETINGELSER

The invention relates to methods and to a device for producing a drinkable mixture (M) from a carrier liquid (TF) and at least one cereal (Z), preferably a solid-like, particulate, and swellable cereal, and/or other small-sized admixtures under aseptic conditions. The problem addressed by the invention is to specify a method and a device of the type defined above that produce, in particular, a drinkable mixture from drinking milk as a carrier liquid and rice and/or oats as a cereal or cereals and by means of which the content of the at least one cereal is increased beyond the extent hitherto achieved in the prior art, the desired properties that can be sensorily experienced, such as perceptible lumpiness and even distribution of the admixtures, are ensured, the use of virgin, commonly available cereals is enabled, and sedimentation of the cereal and/or of the admixtures is prevented. This problem is solved, among other things, by means of a method in which an unbranched pipe flow (RS) in the respective sub-regions of a UHT heat treatment (VW; VE, HE, HH, K) is broken down into a group of pipe-flow sections (rs1; rs2) strung together in a meandering manner and remains unbranched as a pipe flow (RS), and in which, following the objective of preventing sedimentation of the at least one cereal (Z) and/or of the admixtures in the region of the pre-swelling (VQ), an average first dwell time (t1) of the mixtures (G) in associated first pipe-flow sections (rs1) in the region of the pre-swelling (VQ) is shorter than an average second dwell time (t2) in associated second pipe-flow sections (rs2) in the region of the final swelling (EQ) and the subsequent regions of the heat treatment (W).
