Definitions
- the invention relates to a method for producing color-speckled powdery bulk material with non-colored and colored powder constituents and to an apparatus for carrying out this method.
- Powdery bulk goods such as granular detergents and cleaning agents, are sometimes mixed with a small proportion of colored powder components due to their visual appearance.
- white washing or cleaning granules are optically upgraded by metering in colored granules.
- the color granules can have larger grain diameters than the non-colored, white or light basic powder.
- the grain diameter can also be the same size.
- the object of the invention is to provide a solution with which color-speckled powdery bulk material can be produced much more easily.
- This object is achieved according to the invention with a method of the type mentioned at the outset by first producing non-colored powdery bulk material and then spraying some of the non-colored powdery bulk material with a color solution.
- color-speckled powdery bulk material is significantly simplified by this process. All that is required is a plant for the production of bulk goods, for example washing or cleaning agents, in which only non-colored, e.g. white powder is produced. The powder thus produced is then only partially sprayed in a metered manner, so that the desired color sprinkling occurs.
- a suitable atomizing device can also be easily retrofitted, for example in an existing metering system (e.g. batch system of a washing powder preparation) or upstream or downstream.
- the non-colored powdery bulk material is conveyed as a metered powder stream and is sprayed with the color solution from one surface side. Downstream of the spraying, the powder sprayed in this way is then thrown off in the usual way from the conveying device of the metering device, as a result of which a sets intimate mixing with the undyed powder and the desired color speckling occurs.
- the invention also provides a device which has a conveying device for powdery bulk material and at least one atomizing device for color solution which is arranged in the region of the conveying device and acts on it.
- a device which has a conveying device for powdery bulk material and at least one atomizing device for color solution which is arranged in the region of the conveying device and acts on it.
- Such a device can be manufactured in a relatively simple manner and can also be installed in existing metering systems, which can also be done subsequently without difficulty.
- the at least one atomization device is connected via a metering device to a metering container for color solution. In this way, the desired or required dosage of the color components can be easily regulated.
- the at least one atomizing device has an ultra-fine atomizing nozzle. This ensures that the powder is not blown up by the sprayed jet.
- the color speckling of washing powder has an ultrasonic nozzle has proven itself particularly well.
- the color aerosols of the sprayed jet are applied to the surface of a metered powder stream or to the falling powder stream after a powder metering device.
- the conveyor is designed as a dosing belt scale. Since such a metering device is required anyway, it can also be used for spraying paint at the same time, because the powder provides a surface that is easy to spray during metered transport.
- the invention is explained below with reference to the drawing, for example. In a simplified process flow diagram, this shows a device for carrying out the method according to the invention.
- the device initially has a conveying device 1 for powdery bulk material, which in the exemplary embodiment shown is preferably designed as a dosing belt scale.
- a conveying device 1 for powdery bulk material which in the exemplary embodiment shown is preferably designed as a dosing belt scale.
- this conveyor 1 there is a feed hopper 2 in which non-colored, e.g. white or gray, powdery bulk material is stored.
- this non-colored bulk material directly from the production plant (for example detergent powder production plant).
- a plurality of atomizing devices arranged next to and / or one behind the other are arranged downstream of the feed hopper 2, each of which is identified by the reference number 3.
- These atomizing devices 3 are each provided with a preferably ultra-fine atomizing outlet nozzle 4, which can be designed, for example, as an ultrasonic nozzle, which has proven particularly useful for spraying detergent powder.
- the atomization devices 3 are connected via feed lines 5 and metering or regulating devices 5a to a metering container 6 for color solution, for example an agitator 7 can be integrated in this metering container 6.
- This dosing container 6 is connected via a feed line 8 with a feed pump 9 and control fittings 10 to a paint preparation container 11, in which the desired color solution is prepared.
- a paint preparation container 11 for example, colored powder, which is indicated by the arrow 12, and fluid basic paint substance, which is indicated by the arrow 13, are fed into the paint preparation container 11.
- the paint preparation container 11 can be equipped with an agitator 14.
- first non-colored white or gray powdery bulk material e.g. Detergents or cleaning agents are produced in the usual way and are advantageously stored temporarily in the storage bunker 2.
- a metered non-colored powdery bulk material flow is then conveyed from the feed hopper 2 on the dosing belt scale 1 and is sprayed with color solution from the top by the atomizing devices 3.
- the top layer of the powder stream is colored and after the bulk material has been ejected from the dosing belt scale 1, the undyed and colored powder components are automatically mixed and the desired color-speckled bulk material is available.
- the invention is not limited to the exemplary embodiment shown. Further configurations are possible without leaving the basic idea. In this way, the bulk material can also be fed continuously without the feed hopper 2.
