Abstract: A method and an associated apparatus for treating fine-grained material in a spouted bed. Here, the method and design for an associated apparatus for treating fine-grained material in a spouted bed eliminate the drawbacks of the prior art, allow different process conditions in the process chamber to be adjusted in a regulated manner, and has a simple and inexpensive structure. The method is provides that a nearly circular gas flow of the fluidizer is generated in the process chamber (5) by an external annular gap (7) lying on the y-z plane, the diameter of the nearly circular gas flow expands outward in the direction of the x axis inside the process chamber (5), and a nearly circular gas flow of the fluidizer is generated by an internal annular gap (8) lying on the y-z plane, the diameter of the nearly circular gas flow expands inward within the process chamber (5).

Abstract: A method of producing enzyme granulates, enzyme granulates produced By the method, and the use thereof in formulations is provided, for example, for animal feed, foodstuffs, washing agents, rinsing agents or for pharmaceutical uses. The enzyme granulates have a high relative proportion of active enzyme, particular particle size, good shelf life, particularly small rounding factors and/or low residual moisture proportion, and further specific properties. The production of the enzyme granulates is achieved by linking of the thermal conditions in the injection zone and temperature conditions in the remainder of the apparatus. This is achieved by introduction of heated process gasses for drying exclusively in the injection zone. The secure introduction of articles into the injection zone is achieved by the specific geometric arrangement of the apparatus using gravity. The absolute value for enzyme activity of the enzyme granulates can be controlled by the addition of particles as seed material for the granules.

Abstract: A fluidized bed apparatus for batch-by-batch or continuous process control is provided that allows the processes in the fluidization region to be influenced as desired, especially in terms of material movement and dwell time. The fluidized bed apparatus is formed from at least two processing regions and the processing regions are connected to each other by overflow channels. The first processing region is provided with a solids inlet and the last processing region is provided with a solids outlet. For influencing the dwell time, the material to be treated is supplied to at least two processing regions one after the other and flows through these regions, wherein the material transport direction is a cross flow relative to the flow of the fluidization means.

Abstract: A method for producing granules made from malt extract is provided. The method provides for producing granules continuously or in batches under the prevention as much as possible of non-uniform temperature distributions in the production process. Simultaneously, the controllability of the granulation in the production is improved. This is realized by linking thermal conditions in the spraying zone and the temperature conditions in other region of the apparatus. This is achieved such that the supply of the heated process gas for drying is realized exclusively in the spraying region. The reliable supply of particles into the spraying region is performed through the special geometric configuration of the apparatus under the use of gravity.

Abstract: A method for producing enzyme granulates, the resulting enzyme granulates, and their use in formulations, e.g., for animal feed, food, washing means, rinsing means, and/or for pharmaceutical purposes and the like. The enzyme granulates show, in particular, a high relative percentage of active enzymes, certain grain sizes, good storage stability, especially small roundness factor, and/or low residual moisture percentage as well as preferably additional specific properties. According to the invention, the enzyme granulates are produced by linking the thermal conditions in the spray zone and the temperature conditions in the remaining region of the fluidized bed. In the process according to the invention, this is achieved in that the supply of heated processing gas is realized for drying exclusively in the injection region. The reliable supply of particles in the injection region is realized through the special geometrical shape of the apparatus under the use of gravity.

Abstract: The invention relates to a process for preparing nondusting free-flowing pigment concentrates with removal of the water from pigment suspensions comprising polymers and dispersants in a fluidized bed drier. The resulting bead-form pigment concentrates are nondusting and readily free-flowing. The invention further embraces the use of pigment concentrates prepared in this way for coloring plastics and polymers.

Abstract: A process is provided for manufacturing industrial detergents and industrial detergent components in granular or agglomerate form on a dry basis in an essentially horizontally oriented fluidized bed. The finished detergent granulates or agglomerates are distinguished by a homogenous composition of the individual raw material components, including the binder and the moisture content, have a high resistance to mechanical stress, are readily dispersible in water, and are low in dust or almost dust-free. In the process a binder and/or components in the form of solutions, suspensions, or melts are added to the solid material in the fluidized bed via a spray or injection system. Through the energy introduced via the process air, drying and compacting of the agglomerate granulate forming in the injection area of the fluidized bed occur. The supply temperature of the process air is in a range of about 20° C. up to the decomposition temperature of the individual materials.
