Abstract
A process for the preparation of granules of methionine which process comprises (a) forming a mixture of methionine powder, a binding agent and water (b) applying the mixture to high shear rate mixing, thereby forming granules of said mixture; and (c) drying said granules. Granules produced by the aforementioned process characterised by a bulk density of at least 0.6 g/cm3, and a particle siye distribution of from 50 to 2000 microns are also claimed as well as an animal feed composition comprising the granules.
Claims14
A process for the preparation of granules of methionine which process comprises (a) forming a mixture of methionine powder, a binding agent and water (b) applying the mixture to high shear rate mixing, thereby forming granules of said mixture;
- and (c) drying said granules.
A process as claimed in any one of the preceding claims in which the binding agent is selected from cellulose, starch, hydrocolloid gum, polyvinyl alcohol, polyvinyl pyrrolidone, sugar and syrup of sugar.
A process as clamed in any one of the preceding claims wherein the mixture comprises 30 to 82% by weight methionine powder, 0.3 to 10% by weight binding agent and 15 to 65% by weight water.
A process as claimed in any one of the preceding claims in which the mixture further comprises a surfactant selected from non ionic surfactants and anionic surfactants.
A process as claimed in any one of the preceding claims in which the mixture further comprises a salt selected from Group I or II of the Periodic Table.
A process as claimed in any one of the preceding claims carried out continuously or batch.
Granules of methionine prepared according to the process as claimed in any one of the preceding claims characterised by
- (a) a bulk density of at least 0.6 g/cm3, and
- (b) a particle size distribution of from 50 to 2000 microns.
Granules of methionine comprising sodium chloride and having a bulk density of greater than 0.7 g/cm3 and a particle size distribution of from 100 to 2000 microns.
