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 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-proof...

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

Method for preparing enzyme granules (A) by spray drying, is new. Method for preparing enzyme granules (A) comprises: (a) spraying at least one liquid enzyme formulation into a gas stream laden with solid particles; (b) subjecting the liquid-wetted particles in the heated gas stream to drying and granulation; (c) the particles, after a residence time in the gas stream, are separated and recycled in the process volume; (d) the particles are passed to the gas inlet region; (e) fine particles, dust and particles entrained in the process gas are separated and returned to the process as seed material for granule formation; and (f) a circuit-like flow of solid is generated in the axial direction of the reaction volume by supplying material to the gas stream. An independent claim is also included for enzyme granules (A) prepared by the new method.

Description

technical field [0001] The present invention relates to a method for preparing an enzyme granule having the features described in the preamble of claim 1, an enzyme granule thus obtained having the features described in the preamble of claim 17, and its use in Preparation especially according to one of claims 24-27 or 28-29 containing such formulations of enzyme granules (the said application is also part of the possible preferred solution of the enzyme granule preparation method), a method for the preparation of enzyme granules according to the The method of claiming one of the enzyme granules of 30-34 and / or the enzyme granules obtained therefrom are used according to claim 35, and other preferred inventions as described in the following description and the following claims implementation. Background technique [0002] Enzymes are increasingly used in many industrial sectors. This concerns both the quantity and the variety of forms the enzyme is prepared. In general, th...
