Definitions
- the invention relates to a method for producing washable or cleaning-active granules with bulk weights below the value calculated using the normal calculation method is determined, the granules being free-flowing and homogeneous, by Mixing and agglomeration and, if necessary, subsequent processing.
- mixers and granulators like plowshare mixers move through rotating tools characterize, the so-called free-fall mixers are characterized by that they contain no tools and belong to the mixer with rotating containers. In them, the mix is raised and rubbed against the wall or fittings trickles over the surface of the bed under the influence of gravity.
- double cone mixer which is one of the free-fall mixers and in which usually washing or cleaning-active granules with bulk weights are obtained, which confirm the theoretical calculation, the solid ingredients are different as mixed gently in the ploughshare mixer and without destroying the compressor; the inhomogeneity of the product remains. This is an indication of insufficient agglomeration.
- Another problem is the homogeneous incorporation of small components, which only in minor amounts, for example up to about 10% by weight in one Detergents or cleaning agents are used. These include cobuilders, optical Brighteners, sequestering agents, graying inhibitors, soap, colors and fragrances etc.
- the German patent application DE-A-196 51 072 proposes small components of this type for this purpose to accommodate in a separate additive, by using this additive a more precise dosage and a more homogeneous distribution of the small components in the entire detergent or cleaning agent is aimed for.
- Typical admixing components are, for example, peroxy bleaching agents such as perborate and / or percarbonate, which have bulk densities can have between 800 and 1000 g / l, or sodium sulfate, which a Has bulk density of up to 1500 g / l and still in quantities in some agents can contain up to 45 wt .-%. Also heavy sodium carbonates if necessary or bleach activators are suitable as admixing components.
- the admixing components mentioned with bulk weights above 700 g / l can be relative work easily into heavy detergents or cleaning agents; in detergents or cleaning agents, Which bulk weights should be below 650 g / l is not only necessary the other components have a correspondingly lower bulk density, there is also due to the bulk density differences of the individual granular components Risk of segregation.
- heavy sodium sulfate there is also the fact that Sodium sulfate is relatively fine-grained and tends to be in the packaged package anyway during storage and especially during transport on the bottom of the package discontinued.
- the object of the invention was to include granules which are active in washing or cleaning Bulk weights below the theoretical liter weight, which according to the normal Calculation method is determined to produce by mixing and agglomerating, where the finished granules in addition to sufficient storage stability (free-flowing) Above all, they should be homogeneous and at least the bulk density with a constant recipe should be variable within a certain range. Especially heavy ingredients with Bulk weights that are above the desired bulk density of the end product, should be able to be processed without the finished products tend to separate.
- the present invention is under the normal calculation method understood the method in which the bulk density of the finished solid product like already stated above by adding up the individual bulk weights of a respective solid raw material or compounds weighted with its weight proportion in the finished solid product is calculated.
- the liquid components i.e. the granulating liquid or the pelletizing fluids are analogous to their density.
- Raw materials and / or compounds can be used as solids, the latter in the context of this invention at least two different ones usually in washing or Detergent ingredients contain and by conventional techniques such as Spray drying, granulation, roller compaction or extrusion have been prefabricated are.
- the raw materials used can be finely divided, but also of a coarser nature, whereby the method according to the invention has the advantage that even relatively fine-grained material can be processed without problems. Because the manufacturing and subsequent processing From an economic point of view, it can be quite unfavorable for compounds an embodiment of the invention preferred to use only 1 to 3 different compounds Use solids. It is particularly preferred in addition to the compounds at least one other solid raw material as a solid admixture to the To use compounds.
- none spray-dried compounds introduced into the process It is also possible that no compounds at all, but only solid raw materials used as solids become.
- the method according to the invention has the advantage that so-called solid small components can be added directly. For example, proceed that the solids on a conveyor belt, a so-called component collection belt, be weighed together and the addition of the solid small components, especially those that are only used in amounts of at most 2% by weight as the last solid or the last solids directly before the introduction of the solids into the mixer.
- a separate premix of the solids in a separate one Mixer i.e. the production of a so-called premix, which is used in other processes is quite common, is therefore not necessary in the method according to the invention.
- the agglomeration process nor to connect a drying step to the treatment that may have been carried out, however, water can be added in the agglomeration phase and the end products of the process should not tend to stick, it is advantageous in another Embodiment of the invention preferred at least one over-dried solid (Raw material or compound) so that the water content of the solids used or the solid mixture as a whole is lower than the water binding capacity of the total solids or solid mixture corresponds.
- the embodiment of the invention is the aqueous granulating liquid only in the amounts used that the water binding capacity of the agglomerates is not exceeded.
- At least one granulating liquid will be, but preferably introduced at least two different granulating liquids in the process. All in all it is quite possible to have three, four or five, if desired even more different Introduce granulating liquids into the process.
- the granulating liquids can be non-aqueous or aqueous in nature. For example, it is possible that as single granulating liquid water, an aqueous solution or an aqueous dispersion is used. In a preferred embodiment of the invention, however, is used from a single granulating liquid a non-aqueous granulating liquid used.
- a non-aqueous Granulating fluid understood an auxiliary, which is a common ingredient - if necessary in aqueous solution or dispersion - of detergents or cleaning agents and at the process temperature is in the form of a liquid or melt.
- At least two different granulating liquids used are one of the above-mentioned non-aqueous granulating liquids is, while at least one further granulating liquid is water, an aqueous solution or is an aqueous dispersion.
- Liquid or liquefied liquids are particularly suitable as the non-aqueous granulating liquid or melted nonionic surfactants, paraffins, silicone oils, fragrances, fatty acids, meltable polyester and known soil release ingredients of detergents.
- alcohol ethoxylates with linear residues of alcohols of native origin with 12 to 18 carbon atoms, for example from coconut, palm, palm kernel, tallow fat or oleyl alcohol, and an average of 2 to 8 EO per mole of alcohol are particularly preferred.
- the preferred ethoxylated alcohols include, for example, C 12 -C 14 alcohols or C 12 -C 15 alcohols with 3 EO or 4 EO, C 9 -C 1 alcohols with 7 EO, C 13 -C 15 alcohols with 3 EO , 5 EO, 7 EO or 8 EO, C 12 -C 18 alcohols with 3 EO, 5 EO or 7 EO and mixtures thereof, such as mixtures of C 12 -C 14 alcohol or C 12 -C 15 alcohol 3 EO and C 12 -C 18 alcohol with 7 EO.
- the degrees of ethoxylation given represent statistical averages, which can be an integer or a fraction for a specific product.
- Preferred alcohol ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE).

- the amount of water to be added depends on the case, there are no mandatory quantities that will definitely lead to success.
- in a preferred embodiment of the invention is as a granulating liquid amount of water entered depending on the mixture to be agglomerated 0.5 to 10 wt .-% and in particular 1 to 7 wt .-%, each based on the total Mixture. It is irrelevant whether the water is the sole raw material or in In the form of an aqueous solution or in the form of an aqueous dispersion in the process is introduced. However, since preferably no drying step on the agglomeration process is connected, in a preferred embodiment of the invention, water not used as the sole agglomeration aid to the amount of registered To keep water as low as possible.
- Aqueous solutions are those of inorganic and / or organic builder substances prefers. So here come in particular solutions of alkali silicates, Alkali carbonates, but also of polycarboxylates, for example citrates, (co) polymers Polycarboxylates and cellulose ethers such as carboxymethyl celluloses or Methyl celluloses into consideration. But also aqueous surfactant pastes of anionic and / or nonionic surfactants are suitable granulating liquids. For example, highly concentrated pastes of alkyl benzene sulfonates and alkyl sulfates are used become. The use of nonionic is particularly preferred at this point Surfactant pastes such as pastes of alkyl glycosides, polyhydroxy fatty acid amides or the like above-mentioned fatty acid methyl ester ethoxylates.

- liquids (7) in particular nozzles, advantageously 1 to 5 nozzles, different granulating liquids being introduced via different nozzles, but one and the same granulating liquid can also be added via different nozzles.
- Single-substance nozzles are just as suitable here as multi-substance nozzles and / or spraying with gases, in particular air or water vapor, as aids.
- two different nonionic surfactants such as C 12 -C 18 alcohol with 7 EO and C 12 -C 14 alcohol or C 12 -C 15 alcohol with 3 EO are used as granulating liquids, they can either be used as a mixture, via a two-component nozzle or introduced into the process via two nozzles.
- the mixing drum (13) on the larger circular area of the mixing drum (13) on the solids feed (6) to which then the different nozzle lances (7) are attached can advantageously even small liquid components can be distributed homogeneously.
- the upper edge of the tee (5) is at a distance from the inside Mixer wall (14), which is preferably a maximum of 10% of the smallest drum diameter in the mixing zone (1), preferably a maximum of 5% of the smallest drum diameter the mixing zone (1) and in particular 5 to 25 mm, advantageously less than 20 mm, for example 5 to 15 mm.
- the distance can be in the post-mixing zone (2) to the nearest inner mixer wall may be larger than in the mixing zone (1); Values between 100 and 300 mm are quite common.
- heavy solids often from a wide variety Reasons are subsequently added to the agglomeration process become.
- granulated bleach activators which often have a bulk density have from 500 to 600 g / l, count in detergents as desired Should have bulk density below 500 g / l, to the heavy ingredients that can also be used in the method according to the invention.
- Another advantageous compound is a so-called builder compound that predominantly contains inorganic constituents and accordingly inorganic builders. You can set alkaline as desired by choosing the builders become.
- builder compounds used which a maximum of 30 wt .-%, preferably up to 20 wt .-% of organic Components, especially on anionic surfactants and / or nonionic surfactants.
- embodiments can be preferred which only have 2 to 15% by weight contain organic components and above all anionic surfactants.
- Builder compounds of this type are, in particular, those made from carbonates and called silicates, optionally up to 30% by weight, preferably up to 20 %
- surfactants in particular anionic surfactants, but also anionic surfactants and nonionic surfactants
- Particularly preferred builder compounds have between 40 and 70% by weight sodium carbonate, 20 to 50% by weight sodium silicate of the module 2.0 to 3.3 and optionally about 2 to 18% by weight of anionic surfactant, in particular alkylbenzenesulfonate.
- Another interesting compound contains essentially zeolite, crystalline layered Sodium disilicate and polymeric polycarboxylate or crystalline layered Sodium disilicate and citric acid.
- a compound with high organic Proportions such as surfactants and optionally organic cobuilders and a builder compound, that should adjust the washing alkalinity of the finished product combined.
- These two compounds are preferably in weight ratios of 5: 1 to 1: 3 and in particular from 3: 1 to 1: 1.
- the total content of surfactants in the finished product can be in a wide range vary and for example between 5 and 40 wt .-%, based on the finished agent, lie.
- anionic surfactants are preferably used as solids in the agglomerate Mixture given while nonionic surfactants both as part of the solids (Compounds) as well as agglomeration aids can be added.
- the weight ratio the anionic surfactants to the nonionic surfactants in the finished compositions can be 10: 1 to 1:10. In preferred embodiments, however, it is above 1, in particular even above 1.5: 1, for example at 5: 1 or 8: 1.
- the agglomeration effect according to the invention is due to the special mode of action of the Mixer (13) used according to the invention supports. Especially relatively small particles and especially the fine particles with particle diameters smaller than 100 ⁇ m are moved up by the movement of the mixer (13), while relatively coarser particles becoming increasingly smaller in the rotary movement of the mixer (13) and instead towards the post-mixing zone (2) and then to exit from the Mixers (13) are transported into the discharge unit (8) or the conveying device (10), whereby, due to the rolling movement of the individual particle, it compresses the experience individual particles. Such a process is also roll agglomeration or Called roll granulation.
- the tapping bar (5) prevents the highly moved particles and in particular also the fines are only "driven in a circle", as soon as they hit the tee (5) hit, be stripped from this and fall vertically again.
- the geometry the mixer (13) allows that the injected liquid mist not only on the freshly added solids, but also directly into this curtain from relatively fine and sprayed themselves in the ascending and falling movement of the particles becomes.
- the chopping bar (5) prevents the powder from rotating the mixer (13) to the mixer wall (14) pressed and glued. In case should still build up adhesions - depending on the type of added Granulating liquids and their amount cannot always be excluded - see above the knock-off bar acts as a scraper and prevents the adhesive layer from continuing increases.
- the tools reach into the mixed and agglomeration goods and therefore also convey coarser particles, "finished product," upwards, whereby on the one hand the risk of oversize grain generation increases, on the other hand the coarser ones Particles in terms of agglomeration in competition with the smaller particles and above all the fine grain proportions, i.e. the reduction of the fine grain fraction cannot be done effectively enough.
- coarser particles can also be used in the mixer (13) used according to the invention be moved and agglomerated, and this happens the more the flatter the angle of inclination ⁇ , the longer the residence time of the material to be mixed in the mixer (13) and - how already said above - the higher the speed of the mixer.
- a setting option of the angle of inclination ⁇ from 0 to about 30 ° and up to about 70 revolutions per Minute are for the reasons mentioned in a preferred embodiment of the Invention an angle of inclination of the mixer (13) from 10 to 20 °, in particular from 12 to 15 ° with a simultaneous movement of the mixer (13) via the drive (3) from 20 to 70 revolutions per minute and in particular from 30 to 60 revolutions per minute set.
- the bulk density is below 700 g / l, especially below 650 g / l, even if according to the above specified normal calculation method a bulk density of well above 800 g / l would have been expected.
- Such agents can be excellent as a detergent, but also as a compound for one processed detergent.
- the invention thus relates to another Embodiment of the invention laundry detergent, which consists of about 50 to 100 wt .-% of a Compound or product produced according to the invention.
- Fine and coarse-grained fractions that are still present can be made as desired have been screened so far. Fine particles can be returned directly to the agglomeration process while coarse particles due to the lack of tools in the mixer (13) must first be broken up separately before they can be recycled.
- This example relates to the processing of compounds 1 and 2 according to the invention Add further raw materials to agent M1 according to the invention in a mixer according to Figure 1 (list of reference symbols see below).
- the angle of inclination ⁇ was 13 ° and the speed between 40 and 60 revolutions per minute.
- the comparative example contained V1 same compounds and raw materials as M1, but was in a commercially available Double cone mixer manufactured by Teltschik. Similar results were obtained for V1 achieved if, instead of the double cone mixer, a ploughshare mixer from Lödige was used.
- comparative example V2 which has the same composition as M1 or V1 had, instead of Compounds 1 and 2, a spray-dried powder was produced and with the exception of sulfate and other organic material with the same raw materials edited.
- Compound 1 contained 30% by weight of surfactant components, in particular 28% by weight of alkylbenzenesulfonate and / or alkyl sulfate and 3% by weight of nonionic surfactants such as C 12 -C 18 fatty alcohol with about 5 EO.
- the composition of the surfactants can vary within a wide range without affecting the result. For example, 25% by weight alkyl benzene sulfonate, 2% by weight alkyl sulfate and 3% by weight nonionic surfactant with different degrees of ethoxylation in the end product gave the same result.
- Compound 1 additionally contained 50% by weight of inorganic builders, for example zeolite A, zeolite X, zeolite P, crystalline layered disilicate or any mixture from these, as well as 12 wt .-% organic cobuilders such as citric acid, citrate, other polycarboxylic acids or polycarboxylates and / or (co-) polymeric salts of acrylic acid and / or methacrylic acid and / or maleic acid with relative molecular weights between 3000 and 100000.
- organic cobuilders such as citric acid, citrate, other polycarboxylic acids or polycarboxylates and / or (co-) polymeric salts of acrylic acid and / or methacrylic acid and / or maleic acid with relative molecular weights between 3000 and 100000.
- organic cobuilders such as citric acid, citrate, other polycarboxylic acids or polycarboxylates and / or (co-) polymeric salts of acrylic acid and / or me
- the water content of compound 1 was 7% by weight.
- the remaining quantities passed from salts from raw materials.
- Compound 2 consisted of 50% by weight of sodium carbonate and 30% by weight of amorphous Sodium disilicate, 8% by weight of alkylbenzenesulfonate and 12% by weight of water.
- agent M1 30 parts by weight of compound 1, 10 parts by weight of compound 2 and 3 parts by weight of agglomeration aids, in particular 3 parts by weight of C 12 -C 18 fatty alcohol, were used to prepare agent M1 according to the invention and comparative example V1 with about 7 EO, 18 parts by weight of peroxy bleach (perborate monohydrate or percarbonate), 2.65 parts by weight of tetraacetylethylene diamine, 0.5 parts by weight of protease granules, 1.8 parts by weight of foam inhibitor granules, 38 parts by weight of perfume and 33.67 parts by weight of sodium sulfate are used, while for the preparation of V2 75 parts by weight of the spray-dried granules, 18 parts by weight of peroxy bleach (perborate monohydrate or percarbonate), 2.65 parts by weight Parts of tetraacetylethylenediamine, 0.5 parts by weight of protease granules, 1.8 parts by weight of foam inhibitor granules,
- the theoretical liter weight calculated in advance according to the normal calculation method of M1 was 872 g / l.
- Table 1 shows the application properties of products M1, V1 and V2. It can be seen that M1 has advantages in solubility in spite of the higher bulk density than V2. It is also proven that the significant reduction in the bulk density of M1 compared to the value determined using the normal calculation method (only 71% of the theoretical liter weight) and the value of V1 (86% of the theoretical liter weight) brings about very clear advantages in terms of application technology. For V1 it was made more difficult that the residue remaining in the induction chamber hardened. The segregation tendencies were examined in three ways: 1. visually (when several visible layers appear, either recognizable by different particle sizes and / or in the case of partially stained products by concentration of a certain color in one layer), 2.
- the agents were used in household drum washing machines tested with induction drawer at a water pressure of 0.5 bar.
- test machines were Miele W918 and Jo Privileg 1100. There were 5 in each machine Determinations carried out. From the 10 results, the one given below was then given Average formed.
- 100 g of the detergent were added to the dispenser compartment per wash cycle given.
- the detergent residues were removed from the wash-in drawer and the induction chamber placed separately on a watch glass with a rubber wiper and balanced. 30% moisture was subtracted from these moist residues.
- the "dry residues" from the drawer and chamber were added and from the Sum formed the mean value, which is given in Table 1.
- Example 1 was repeated, except that agglomerating liquids were added to 2.5 parts by weight of nonionic surfactant now also used 2 parts by weight of an aqueous dye solution. A homogeneously colored product M2 was obtained, which despite the increased content Granulating liquid and especially water did not tend to stick.
- Example 1 was repeated; However, in addition to the 3 parts by weight of nonionic surfactant, water was now added as a further granulating liquid in the amounts indicated in each case: with additions between 1 (M3) and 4.5 parts by weight of water, bulk densities between 620 and 640 g / l were obtained , However, the wash-in behavior deteriorated almost continuously.
