Embodiment 1

[0043] Embodiment 1: preparation enzyme granule

[0044] An enzyme preparation is sprayed into the device characterized by the above-mentioned structure. The enzyme preparation additionally contains stabilizers and binder components in the enzyme solution, and has a final concentration of solid matter of about 22 mass percent. The process chamber is characterized by a rectangular cross-section and has 0.15 x 0.2 = 0.03 m above the sloped side walls 2The cross-sectional area and the height of about 1m. A process air flow of approximately 180 kg / h heated to approximately 140° C. is conveyed via 2 gas supply gaps distributed longitudinally through the device. The liquid formulation was sprayed into a process air jet with a flow rate of about 50 g / min through a vertically upward-spraying two-component nozzle supplied with compressed air. About 500 g of enzyme granules are in the process chamber. The process air is cooled by the evaporation process and leaves the unit at about 4...

Embodiment 2

[0051] Example 2: Enzyme granules with phytase from Aspergillus niger:

[0052] Commercially available phytase (Natuphos 5000L, BASF, Ludwigshafen, Deutschland) was dialyzed to remove preservatives and salts using demineralized water and ultrafilters with a porosity that would not allow the enzyme to pass through. The enzyme is then ultrafiltered to obtain a high-concentration liquid enzyme preparation.

[0053] Polyvinyl alcohol as a binder was added to 25% by weight of this liquid enzyme preparation with a phytase-activity of 24000 FTU / g and a dry content of 25% by weight. The remaining 75% by weight solution was spray-dried in the apparatus described in Example 1 with an air inlet temperature of 180°C and an exhaust temperature of 70°C.

[0054] Pack the spray-dried enzyme powder into a dust-proof docking container. It yields an enzyme powder with 90000 FTU / g phytase-activity and 95% dry matter. The container with the spray-dried enzyme powder is docked with the dust-pro...

Embodiment 3

[0057] Example 3: Application of the salt- / binder solution

[0058] A pilot plant with 4 inlet chambers and 4 nozzles was used. Proteases are used as enzymes. Inorganic alkali metal salts and customary binders are used as salt / binder components. The portion of the ingredient is expressed in % by weight ("%").

Abstract

The invention relates to method for production of enzyme granules, enzyme granules produced thus and use thereof in formulations, for example, for animal feed, foodstuffs, washing agents, rinsing agents or for pharmaceutical uses and similar. The enzyme granules have a particularly high relative proportion of active enzyme, particular particle sizes, good shelf life, particularly small rounding factors and / or low residual moisture proportion and preferably further specific properties. According to the invention, the production of the enzyme granulates is achieved by a linking of the thermal conditions in the spraying zone and the temperature conditions in the remainder of the apparatus. The above is achieved in the inventive method by means of the introduction of heated process gases for drying exclusively in the nozzle region. The secure introduction of particles into the nozzle region is achieved by the special geometric arrangement of the apparatus using gravity (see figure). The absolute value for enzyme activity of the enzyme granules can be controlled by means of addition of inert particles as seed material for grains.

Description

Technical field [0001] The present invention involves a method of enzyme particles that are used to prepare the characteristics described in the preliminary sequence of claims 1, and a enzyme particle granules that are obtained with claims 17, and they are applied toPreparation, especially the preparation agent containing this enzyme granules in accordance with one of the claim 24-27 or 28-29 (the application is also part of the optional plan for the preparation method of enzyme granules), one is used to prepare according to rights according to rights.The methods and / or the enzyme particles obtained from the required 30-34 enzyme particles are required by the application according to the application of claim 35, and the later instructions and the subsequent claimsImplementation. Background technique [0002] Enzymes have been widely used in many industrial departments.This involves both the amount of enzymes and various forms.In general, enzymes exist in liquid form or as dry sub...
