Methods and UHT plant for producing a drinkable mixture from a carrier liquid and at least one cereal under aseptic conditions

Abstract

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).

Description

technical field [0001] The present invention relates to a potable mixture for the manufacture under aseptic conditions of a carrier liquid and an admixture of at least one cereal, preferably solid, granulated, expandable cereal and / or other small pieces and a device for carrying out the method, which is configured as a UHT device (UHT: Ultra-Hoch-Temperatur), and in particular a drinkable mixture consisting of drinking milk as carrier fluid and Compositions such as rice and / or wheat and / or oats as cereals are manufactured by using the method according to the invention and the device according to the invention. [0002] A drinkable mixture in the present case means that the mixture does not have to be edible in a consistency that can be scooped up from a spoon, but can be ingested without problems using a straw or straw tube. The term "cereals" here includes in the following, besides rice and oats, for example also wheat soaked only in cold water and also solid, small pieces o...

Problems solved by technology

It is well known that shear forces occur at deflector turns, discontinuous cross-sectional transitions, branches or junctions, which cannot be completely avoided in UHT plants of the type described
