Definitions
- Granulated and therefore free-flowing bulk goods are used in numerous Production areas, e.g. in the detergent industry in increasing Dimensions used and replace the powdery, poorly flowing products.
- EP-A-376 360 describes a process for producing solid, free-flowing, bleach-active granules containing at least one water-insoluble peroxyacid contain hydrate-forming inorganic material, known, the manufactured granules due to low tendency to dust formation ("dust-free") should honor.
- the bleach-active granules are to be produced by mixing solid peracid such as diperoxydodecanoic acid (DPDA) with anhydrous hydrate-forming inorganic material, such as sodium sulfate, take place, the Water content of the mixture below the maximum hydrate water content of the hydrate-forming inorganic material must lie and the temperature during of the mixing process less than the hydration temperature of the must be hydrate-forming inorganic material.
- DPDA diperoxydodecanoic acid
- the object of the present invention is an inexpensive and energy-saving process for the production of low-dust granules, especially those that contain temperature-sensitive substances to deliver.
- the invention relates to a method for producing low-dust Granules, characterized in that on a particulate starting material an aqueous solution or suspension of a hydrate-forming compound is applied, the particulate starting material during the Applying the aqueous solution or suspension a temperature below the Has transition temperature of the hydrate-forming compound and the aqueous Solution or suspension a temperature above the transition temperature has, then or simultaneously granulated and the granules obtained optionally dried.
- Granular constituents which are suitable for the production of granules or the granules themselves are used as particulate starting materials for the process according to the invention.
- the terms granulate components and granules are to be understood broadly. It has been shown that the process according to the invention is not limited to certain granule components or granules, but rather that all granule components and granules can be used as particulate starting materials to which an aqueous solution of a hydrate-forming compound can be applied.

- the granules may be specific contains additional components.
- additional components examples of this are chelating systems, Dyes and agents for regulating the pH. It is known that metals are able to catalyze organic or inorganic per-compounds decompose. To overcome this problem, the granules can up to 3% by weight of a chelating agent can be added.
- Preferred compounds are inorganic or organic phosphates or phosphonates or Aminomethylene carboxylic acids. Examples of this are Ethylenediaminetetramethylenephosphonic or carboxylic acids or Diethylenetriaminepentamethylenephosphonic acid or its salts.
- Means of Adjusting the pH will change or maintain the pH value used within the granules. Examples include citric acid, Fatty acid or succinic acid or salts such as silicates, phosphates or Sodium bisulfate.
- Granules are used as starting materials and to reduce these granules with the aid of the process according to the invention Granules are processed further. Have the finished granules used generally the typical granulate structure as described above has been.
- transition temperature is to be understood as the temperature at which the hydrate-forming compound releases or takes up the bound water of crystallization. If sodium sulfate is used as the hydrate-forming compound, the transition temperature is 32.5 ° C. Below this transition temperature, the sodium sulfate forms a decahydrate with the water of crystallization. Above this temperature, most of the crystal water is released again.
- Sodium acetate, sodium carbonate, zinc nitrate, sodium sulfate, magnesium sulfate, magnesium nitrate, lithium bromide, sodium phosphate, sodium hydrogen phosphate or mixtures thereof are preferably used.
- Suitable apparatus for the production of the low-dust granules are, for example, mixers, extruders or pelletizing machines.
- Suitable mixers are those which can be operated batchwise or continuously and which permit mixing under high shear forces. Examples of such batch mixers are "Dry Dispenser” ® (Baker, Perkins, Peterborough, GB) "Diosna-Pharmamix” ® (Diercks, Osnabschreib, DE) "Matrix” ® (Fielder Ltd., Eastlake, GB) “Baumeister” ® (Ruberg, Paderborn, DE) “Ruberg high-performance mixer” ® (Ruberg, Paderborn, DE) "MTI, type EM” ® (MTL, Detmold, DE) and “Eirich Mixers” ® (Eirich Hardheim, DE).
- Lödige Ploughshare Mixer ® (Lödige Maschinenfabrik, Paderborn) "Lödige Recycler CB” ® (from Lödige Maschinenfabrik, Paderborn).
- An example of a continuously operated mixer is the “Konax continuous mixer” ® (Ruberg, Paderborn, DE).
- extruders are “Alma” ®, Unica “®,” Xtruder “®, and” Werner Pfleiderer “®.
- common pelleting machines are the products from Simon Heesen or the Maromarizer from Russel Finings Ltd., London, GB.
- Other apparatuses that can be used to produce the low-dust granules by the process according to the invention are fluidized bed mixers in which different temperature levels can be set.
- the particulate starting material is placed in a suitable apparatus, preferably given a fluidized bed granulator.
- the particulate starting material consists of the individual Granulate components, so the water-insoluble advantageously Components, such as active substance, optionally with the addition of part of the hydrate-forming compound, presented in the apparatus and the device remaining water-soluble components with the solution of hydrate-forming Connection applied.
- active substance such as peracid

- Starting materials it is advisable to while spraying granulate. But it is also conceivable that the solution partially or completely is sprayed on and then the granulation takes place. It has shown, that the process of granulation with improved properties of the used granules in terms of mechanical strength and thus low-dust granules.
- the amount of solution is preferably granted so that it primarily arises Wet granules between 8 and 20 wt .-% water.
- Suitable processes can be used for spraying and granulating Connect drying steps, if necessary, in the same apparatus, however can also be carried out using other gentle methods.
- the additional drying is only necessary if a particularly low one Water content of the granules according to the invention is desired.
- the method according to the invention has been shown that by the selected Temperature ratio between the particulate starting materials and the Solution, after spraying part of the hydrate-forming compound crystallized out and a heat of crystallization released Drying effect of the granules is achieved.
- the low-dust granules produced in this way have one Granule size distribution in the range from 0.1 to 5 mm, preferably 0.4 to 3 mm.
- Granules produced subsequently inert coatings of various Kind be it in the form of closed films or in the form of deposited powder, to apply, but it is just an advantage of the present invention without one get along such measure.
