| titleOfInvention | The extracting method of a kind of L-Trp and device |
| abstract | The present invention provides extracting method and the device of a kind of L tryptophan, the method mainly comprises the following steps: after L tryptophan fermentation liquid intensification sterilizing, acid adjustment, filter cleaner liquid through tubular ultra-filtration membrane and filter dope, ultrafiltration membrance filter clear liquid through evaporation and concentration, crystallize to obtain L tryptophan crystal and crystalline mother solution, decolour after L tryptophan dissolution of crystals and through roll-to-roll ultrafiltration membrane filtration, the destaining solution of rolling ultrafiltration membrane through evaporation and concentration, crystallize, dry to obtain L tryptophan, twice crystalline mother solution of rolling ultrafiltration membrane concentrated solution is dried and feed vector is hybridly prepared into mixed fodder.The extraction of L tryptophan is combined by the present invention with feed manufacturing, simplifies the extraction process of tryptophan, improves the purity of product L tryptophan, improves the utilization rate of product and by-product, decreases the pollution producing waste liquid etc. to environment simultaneously.The present invention has certain economic benefit and environmental benefit. |
