The invention relates to a nozzle device (3) in a dissolving apparatus for dissolving a solid (F) in a solvent, preferably for dissolving a powdery solid in water. The nozzle device comprises a mixing tank (1) from which the solvent-solid suspension is removed in the bottom part (1a) thereof whereupon the suspension is subsequently pumped outside of the mixing tank (1) through a circulation line (6) and is returned once again. The aim of the invention is to reduce the dissolving time in the mixing tank (1) with regard to that of prior art dissolving apparatuses of the generic type and to simplify the apparatus itself. To these ends, the invention provides that the suspension is introduced into the mixing tank (1) via the nozzle device (3) arranged in the bottom part (1a) of said mixing tank. In addition, the invention provides that the nozzle device, starting from a feed tube (3a) and when viewed in a direction of flow, branches into an annular gap nozzle (3c) and a tubular nozzle (3d), that the annular gap nozzle (3c) generates an annular gap flow (R), which is oriented in an essentially transversal manner with regard to the longitudinal axis of the mixing tank (1), and that the tubular nozzle (3d) generates a driving flow (T) which, with regard to the longitudinal axis of the mixing tank (1), has both an axial and tangential directional component oriented toward the top part (1c) of the mixing tank.

わち水の中で懸濁させることが必要となる。In the beverage industry, it is often a problem to make additives that are present as solids in powdered form into aqueous solutions, such as citric acid and sweeteners. This is because such an aqueous solution can be further processed in the process of manufacturing the beverage. In order to dissolve the solid in question, first of all it is necessary to suspend it in a solvent, ie water.

時間を必要とする。BACKGROUND OF THE INVENTION It is known to put the amount of solids to be dissolved in, for example, a mixing tank which contains the amount of water necessary therefor and then to suspend them by means of a stirring device. The stirring device is composed of, for example, a stirrer driven by a motor. further,
By pumping the solvent and solid suspension through the circulation pipe outside the mixing tank and back into the mixing tank, the stirring effect and the suspension are further improved. In this case, the suspension is usually withdrawn through the bottom part of the mixing tank and returned again in the region of the cylindrical mantle part. Dissolving citric acid or sweeteners requires dissolution times of, for example, 15 to 20 minutes in the case of dissolution devices of this type.

クとなる構成部品だからである。In addition to the basic requirement that the dissolution time be as short as possible, there are drawbacks with the motor-driven stirring devices of the known dissolution devices. Because, on the one hand, such agitators are relatively expensive in terms of equipment as such and, on the other hand, are often called so-called automatic clean-up (CIP) cleaning.
e. Cleaning is very difficult or can only be done inadequately without the use of a means called "in-situ cleaning", and the so-called "rinse blind spot" is used when removing the cleaning liquid from the mixing tank. This is because it is a component that becomes a bottleneck in cleaning, which causes

No. 5,564,825, a circulating flow is taken out of the mixing container at a central portion of the bottom surface of the container on the lower side, and is supplied to the mixing container via a nozzle at an interval from the longitudinal axis of the container. The mixing container is known. This nozzle combines an annular interstitial flow transverse to the long axis of the mixing vessel with a hole-type nozzle for purely axial discharge.

【０００９】 本発明の目的は、当分野に属する種類のノズル装置を備える公知の溶解装置に
比べて、混合タンク内での溶解時間を短くすることである。The object of the present invention is to reduce the dissolution time in the mixing tank as compared with known dissolution devices with nozzle devices of the type belonging to the field.

Advantageous embodiments of the device with the proposed nozzle device are the subject of the dependent claims.

管状ノズルを介して吐き出される。Unlike known melting devices of the type belonging to the field, a nozzle device is provided which branches into an annular gap nozzle and a tubular nozzle when viewed in the flow direction starting from the inlet tube. The annular gap nozzle then produces an annular gap flow oriented substantially transverse to the longitudinal axis of the mixing tank. The remaining partial flow of the suspension supplied is

滞領域がそれによって確実に回避される。By virtue of the above-mentioned requirements, convection is created in the mixing tank via the tubular nozzle, which entrains the entire contents of the tank and circulates it both vertically and tangentially. The other part of the suspension flow, which is discharged through the annular gap nozzle, intersects mainly with the downward convection, which leads to an intensive mixing of the suspension on the one hand and, on the other hand, to such highly energetic energy. Abundant cross-flow has a positive effect on suspension conditions. Both suspension withdrawal and supply take place via the bottom part of the mixing tank, so that convection and annular interstitial flow will necessarily intersect. Thus, convection entrains the entire contents of the tank in a scheduled manner into the mixing and dissolution processes, thereby ensuring that stagnant areas in the tank where mass exchange conditions are less favorable are avoided.

It's known. By this measure, the annular interstitial flow is discharged over the entire cross-sectional area of the mixing tank, thereby intersecting the convection flowing downwards over the entire circumference of the cylindrical jacket of the mixing tank.

ンクの底面部分にただ１つの開口部しか必要ない。As further proposed below, the nozzle device provided with the proposed nozzle device is such that the inlet tube of the nozzle device is adapted to pass through an outflow housing which serves to remove the suspension from the bottom part. There is an advantage that the dissolution apparatus is simplified. In this case, only one opening is needed in the bottom part of the mixing tank.

好都合な溶解条件と懸濁化条件が得られる。If, as shown in another embodiment, the inlet pipe is arranged coaxially with the longitudinal axis of the mixing tank in the bottom part, on the one hand the configuration is further simplified and, on the other hand, the mixing The fact that the generation of the flow in the tank is almost axisymmetric provides exceptionally favorable dissolution and suspension conditions.

For this purpose, it is proposed to connect the solid supply device to a suction line provided between the outlet housing and the circulation pump.

ると、懸濁化と溶解をさせるときの有利な条件が得られる。The average feed velocity in the lead-in pipe is v = 2 to 3 m / s, the average annular gap velocity in the annular gap nozzle is v 1 = 10 to 18 m / s, and the average pipe velocity in the tubular nozzle is v 2 = 3. If the cross-sectional area of the nozzle device is set to be 7 to 7 m / s, advantageous conditions for suspension and dissolution can be obtained.
