Definitions

  • the invention relates to a method for mixing and dosing solid doses, such as at least one cereal, in particular a solid-like, particulate, swellable cereal, and / or at least one other small admixture, in a carrier liquid with which a mixture of the carrier liquid and the at least one solid dosage material is produced, in which a volume of carrier liquid and the at least one solid Dosiergut respectively fed forcibly in stationary operation and all mixing components are mixed together in a stationary volume of the mixture, in which the mixture with a constant volume flow mixture steadily and forcibly from the volume presented is removed, in which the presented volume, which has a free level, regulated by this free level and thus kept constant, in which the volume flow carrier liquid and optionally a volume flow of air kept constant and steady and are provided continuously and each quantitatively be preset and can be changed within limits, in which the volume flow carrier liquid is introduced below the free level in the mixture, that in this flow-mechanically a rotational flow is generated in which the at least one solid Dosiergut each in
  • the mixture is at the end of its further treatment in a metering downstream process plant to a drinkable mixture, preferably consisting of drinking milk as a carrier liquid and the at least one solid Dosiergut, such as rice or / and oats as Zerealie / n, prepared by application of the method and the device according to the invention.
  • Drinkable mixture in this case means that it does not have to be consumed in spoonable or spoon-solid consistency, but can be easily absorbed with a straw or drinking straw.
  • the term cereal should in addition to rice and oats, for example, include wheat grains, which are watered only with cold water, and other solid-like, small-piece admixtures such as fruits, nuts or seeds.
  • Solid-like should be considered a cereal or admixture, if it is not destroyed by heat or mechanical action in the treatment process and thus, for example, largely retains its grain structure.
  • the term "small piece" is intended to quantify a cereal or admixture that is still perceptible with a minimum size when drinking (for example, seeds or the like having a largest particle diameter of 1 to 2 mm) or that is still drinkable with a maximum particle size of not more than 5 mm, especially with a straw or drinking straw.
  • the DE 38 03 217 A1 discloses an apparatus for mixing and dosing solid and liquid doses, such as powders, granules or the like.
  • water and liquid dosing such as dispersions, emulsions, with water-immiscible properties.
  • the device has a mixing reactor chamber, wherein the doses are introduced by means of air in the closed, pressurized mixing reactor chamber and a distance air cushion between the water and the Dosiergut is maintained.
  • the forced metering of the metered goods via a metering device in which a driven ball is arranged, in which three blind holes are incorporated, whose positions are arranged to overlap a solids inlet and a solids outlet.
  • the metering device has a connection for a ventilation line and the mixing reactor chamber has a connection for a supply line, is supplied via the air and thus the solids dosage is conveyed into the mixing reactor chamber. It is a quasi-portioned entry of the solid in a space in the metering device, which also air is supplied. In what way, after the solid has been introduced into the metering device, it is mixed with the air supplied via the aeration line and then further treated on the way to the exit from the metering device, it is not disclosed.
  • the portionwise delimitation of, for example, moist rice grains in blind holes and their subsequent emptying by gravity alone does not seem suitable for metering a dosing material of this kind safely and with the necessary quantity-proportional accuracy into a carrier liquid.
  • the DE 602 18 450 T2 involves dissolving powder in water using a stream of water in conjunction with a jet apparatus to aspirate and transfer the powder to a stirred tank.
  • the latter is divided by a plurality of transverse to the longitudinal axis of the container baffles arranged in superimposed chambers, which are each connected by a central opening. Through the central openings extends a stirrer shaft, which drives a stirring pad in each chamber.
  • Powder should also be understood to mean swellable particulate material in water.

  • drinkable mixtures of drinking milk as carrier liquid and rice and / or oats as cereal (s) are desired.
  • cereal-admixed cereals for example rice and / or oats, do not completely dissolve, but that their lumpiness, as uniformly distributed and isolated as possible, remains palpable during drinking. This requirement also relates to other small-sized admixtures that can be accommodated in the carrier liquid.
  • a drinkable mixture for example consisting of drinking milk and oats and / or rice
  • the aim is that on the one hand the oats in a native state, namely cold and dry, can be dosed into the carrier liquid drinking milk, and on the other hand, the use of so-called.
  • "Allerweltsreis" is possible, which only needs to undergo a special, adapted pre-cooking before its dosage.
  • rice is termed a rice that has different cooking and sterilizing behavior, depending on variety, origin and natural crop-related fluctuations. Such commodity-related fluctuations usually affect the end product; they should be manageable and compensable.
  • the rice grains pretreated in this way are of sticky consistency and tend to conglomerate with other rice grains. This makes their quantitatively uniform dosage in the carrier liquid and its uniform distribution in this problematic.
  • the rice content is to be less than 6% and possibly less, because a drinkable, relatively low viscosity mixture thereof is desired, then the present dosing methods and devices will fail.
  • solid doses such as at least one cereal, in particular a solid-like, particulate, swellable cereal, and / or at least one other small amount of admixture

This ensures a clearly defined discharge of the mixture from the volume presented and at the same time an approximately constant and steady flow, seen in the direction of flow, in the volume presented subordinate areas of further treatment of the mixture reaches as free as possible from stagnant and / or uncontrolled oscillating flow areas.
  • the presented volume of the mixture which has a free level, regulated above this level and thus kept constant.
  • the free level reaches the at least one solid Dosiergut, the dose to Zerealie, preferably in the carrier liquid, whereby a trouble-free dosage is promoted.
  • volume flow carrier liquid and optionally a volume flow of air and the supply of at least one solid dosage material are each quantitatively presettable and can be changed within limits.
  • the presettableness of these sizes makes it possible to set the proportion of the at least one solid metered material to a desired quantitative value.
  • the variability makes it possible under changing operating conditions, e.g. in the event of fluctuations in the volume flows, to adjust the desired and / or required residence time. Safety and reliability of the mixing and dosing process are improved if the at least one solid dosage material is forcibly supplied.
  • the carrier liquid is introduced in a manner known per se into the mixture in such a way that a rotational flow is generated in it by flow mechanics.
  • a rotational flow is generated in it by flow mechanics.
  • each dosed at least one solid dosage remains a clearly defined mean residence time in the volume presented and there mixed according to this mean residence time together with the supplied carrier liquid and with the volume introduced mixture and uniformly distributed in this mixture.
  • the residence time is defined as the quotient of the volume presented and volume introduced by this volume and planned volume and volume flows entering the volume presented kept constant and provided steadily and continuously and continue to the volume flow forcibly evacuated from the volume presented Mixture is also kept constant and steadily pronounced, the residence time is clearly defined and constant in trouble-free dosing.
  • the dosing conditions are therefore clearly defined, reproducible at any time and constant in the scheduled and trouble-free operation.
  • the invention provides that the presented volume of the mixture can be preset within limits.
  • the dosing at least one dosing divided into more than one volume flow and is introduced separately from each other in the submitted volume.
  • a simultaneous dosing of several and different solid dosing can be realized in the carrier liquid, on the other hand increases this process variant in the dosage of only a single solid dosing the reliability and safety of the dosing, because the entry surface of the volume presented inevitably increased accordingly ,
