Definitions

• the invention relates to a method according to the preamble of patent claim 1.
• FIG. 1 schematically examples of the inner
• the agglomerate according to the invention is not thermoplastic and contains water-containing gelatin as a binder, which firmly binds the individual solid particles to one another. It is important to use the smallest possible amount of gelatin so that the properties of the gelatin do not adversely affect the properties of the solid particles which are in the foreground.
• the binding capacity is still sufficient if the vol .-% of gelatin is smaller than the vol .-% of pores in the agglomerate grains, so that the gelatin does not completely fill the pores.
• the amount of water attributable to the gelatin contained in the granular agglomerate should correspond to the natural water content of gelatin. This depends on the prevailing air humidity ("equilibrium moisture"). It is usually between about 10 and 12% by weight, but can be up to about 16% by weight at high atmospheric humidity.
• the rheological properties of the agglomerates correspond to those of the starting materials. This means that in the case of non-thermoplastic solid starting materials, the agglomerates produced therefrom also have these properties to have .
• agglomerate according to the invention allows rapid dispersion and dissolution, for example in the case of so-called “instant products”, that separation processes, for example in the case of agglomerated medicines and animal feed, can be avoided and that appropriate additives can also be used in the Agglomera ⁇ tion can achieve a depot effect, especially with fertilizers and pesticides.
• the granular agglomerates according to the invention are particularly advantageously produced with the aid of extruders, in particular screw extruders, in a single work cycle.
• the ability of the gelatin to dissolve in water is used. Any viscosity can be set by means of temperature and amount of solvent. Solvents other than water are also suitable, for example glycerol or mixtures of glycerol and water.
• the extruders used to produce the agglomerate according to the invention are preferably co-rotating twin-screw extruders with a relatively long process length.
• the long process length of the twin-screw extruder is necessary because all of the work processes essential for the production of the agglomerate take place in the extruder: the binder (gelatin, gelatin hydrolyzate or a mixture of gelatin and gelatin hydrolyzate) is dissolved in the solvent, heated, Additives are added that become agglomerating substances added and incorporated homogeneously.
• a twin screw extruder is advantageous because it can be used to achieve particularly good homogenization. Homogenization is achieved on the one hand by kneading in the gap between the two screws and the use of special mixing parts, on the other hand, with the double screws rotating in the same direction, no complete chamber shut-off is achieved, so that the mass can flow back around the two screws . Both effects guarantee a sufficient mixing of the binder with the solvent and incorporation of the solid particles and homogenization of the highly viscous pseudoplastic mass to be extruded.
• the binder e.g. B. gelatin
• the liquid solvent e.g. B. water.
• D is the inside diameter of the screw extruder.
• the dusty solids to be compacted are added.
• the addition can take place, for example, via a stuffing screw known per se.
• the viscosity of the mass is greatly increased by adding the substances. Depending on the particle size and amount, the viscosity can increase to a multiple of the low-viscosity gelatin solution.
• FIG. 1 shows schematically a first typical form of the internal or microscopic structure of an agglomerate according to the invention.
• Individual particles 1 of a solid for example a dust-like pigment, are (due to the processing described in the extruder, in particular screw extruder) essentially completely surrounded by a thin gelatin skin, which binds the individual particles firmly to one another or agglomerates due to their adhesive force. Here remain between the individual Particles 1 gelatin-free pores 3.
• the agglomerate shown schematically in FIG. 2 differs from that according to FIG. 1 essentially in that the gelatin 3 contains the particles 1 - z. B. because of poor wettability - is not completely encased, but is only present in some areas on the circumference of the particles and there is an "adhesion" of the individual particles.
• the relative amount of gelatin is so small that the pores between the particles 1 are not completely filled with gelatin 2.
• 300 g / h gelatin with a water content of about 11% by weight corresponding to the equilibrium moisture content are metered continuously into a first area (feed zone) of a twin-screw extruder of 48 D.
• 300 g / h of water are continuously added at another metering point via a valve. The temperature in this area rises steadily from 25 to 80 ° C. over its length.
• the temperature is increased to 95 ° C.
• the gelatin is completely and homogeneously dissolved in this area with the help of the double screw.
• the granular agglomerate obtained in this way is very strong and the individual grains have a smooth surface.
• Example 2 The procedure is as in Example 1. However, 500 g / h of gelatin are metered in and 250 g / h of water are added via a valve. 2 kg / h of sugar are fed in via a stuffing screw. The pseudoplastic mass obtained in this way is extruded at a pressure of 20 bar. The extruded strands are dried and granulated into a granular agglomerate.
• the agglomerate is suitable, for example, as a compound for use in the confectionery industry.
• Example 4 The procedure is as in Example 1. However, 250 g / h of gelatin hydrolyzate are used when the same amount of water is added. 2 kg / h of a mixture of sugar, citric acid, yellow and red color and orange aroma are added via the stuffing screw. There is no separation of the individual components, but rather a granular agglomerate of these components results, which can be fed to further processing in the confectionery industry.
• Example 4
• Example 2 The procedure is as in Example 2. However, 125 g / h gelatin hydrolyzate and 125 g / h gelatin are used. The water addition is unchanged. 250 g / h of herbicides are then continuously mixed into the solution thus obtained.
• Additives in particular plasticizers, emulsifiers, wetting agents and / or non-stick agents, can be added to the gelatin fed into the screw extruder in a known manner.
• Suitable plasticizers are, for example, glycerol or sorbitol, for example amine oxide or Na lauryl sulfate are suitable as wetting agents.
• Mg stearate or montan waxes have proven to be useful as anti-adhesive agents.
• the amount of water in which the gelatin is dissolved can be between 50 and 300% by weight based on the weight of the gelatin.
• the screw extruder is operated at temperatures between 30 and 140 ° C., preferably at temperatures between 30 and 100 ° C.
• the increased pressure prevailing in the extruder can be between 5 and 100 bar.
