Granulated animal feed additives having high bulk density were obtained by adding a surface-active substance to a fermentation broth containing amino acid before spray-drying, wherein low residual moisture levels were achieved at high spray rates and low granulator temperatures.

L-amino acid-containing feedstuff additive

The present invention relates to a process for producing a particulate composition containing methionine, methionylmethionine, potassium in the form of potassium salt and ammonium sulphate, and use thereof.

Dipeptide-containing granular material

By substituting biomass with a surface-active substance in a fermentation broth containing amino acid before spray-drying, granulated animal feed additives with improved product specifications were obtained.

Process for fluidized bed granulation of amino acid-containing fermentation broths

A process for the production or coating of granules in a fluidized bed, which includes heating a fluidized-bed gas to produce the fluidized bed, and applying a liquid medium containing a granule-forming or coating-forming compound, or at least one reaction component therefore, by spraying particles located in the fluidized bed and at a same time vaporizing an organic solvent contained in the liquid medium, said particles having a smaller mean diameter than that of particles to be produced. The process also includes partial condensation of an organic solvent from at least a portion of a fluidized-bed waste gas leaving the fluidized bed, and re-heating the fluidized bed-gas leaving the condensation device and reintroducing the re-heated gas into the fluidized bed.

Process for the production or coating of granules, apparatus for carrying out the process, and granules obtainable thereby

The invention relates to a process for the granulation of an animal feedstuffs additive comprising amino acids or vitamins in a circulating fluidized bed, wherein the additive is preferably a fermentation product and optionally comprises further constituents from the fermentation broth.

A process and a device for producing anhydrous alkali sulfide, wherein an alkali sulfide solution, alkali sulfide suspension, alkali sulfide dispersion or alkali water of crystallization melt is dried by spray drying with inert drying gas loaded with water vapor.

Spray drying process for producing anhydrous alkali sulfide

A process is disclosed for the preparation of anhydrous sodium sulfide by heating sodium sulfide having a water content of from 38 to 40% in a contact drier in vacuo, the temperature of the solid to be dried being increased from approximately 20&deg; C. at the solid inlet to &gE;180&deg; C. at the solid outlet.

Process for the preparation of anhydrous sodium sulfide

A process for the preparation of aqueous sodium methioninate solutions having a low sodium carbonate content from the crude hydrolysis mixtures obtained in the hydrolysis of 5-(.beta.-methylmercaptoethyl)-hydantoin with from 1.1 to 6 equivalents of sodium hydroxide and/or sodium carbonate, by separating off sodium carbonate monohydrate while heating, and granulates subsequently prepared from those solutions by various processes.

Process for the preparation of aqueous sodium methioninate solutions and

A process for the direct preparation of alkali metal cyanide and alkaline earth metal cyanide granules from an HCN-containing gas and an aqueous solution or suspension of an alkali metal or alkaline earth metal hydroxide. The reaction is performed in a reactor for fluidized bed spray granulation, wherein a solution or suspension of the hydroxide is sprayed onto seed granules of the cyanide being prepared and at the same time a hydrogen cyanide-containing gas is supplied to the reactor and water is evaporated by means of a fluidizing gas. The preferred fluidizing gas is steam. The reaction gases from a BMA or Andrussow process may be quenched with water and the gas mixture used as fluidizing gas. By using a CO.sub.2 -free HCN-containing gas, alkali metal cyanide granules with advantageous properties, including a combined concentration of alkali metal carbonate and alkali metal formate of less then 0.4 wt. %, are obtainable.
