Description

Technical Field

[0001] The utility model relates to the technical field of amino acid production and processing, in particular to a feeding device for extracting L-leucine from hair. Background Art

[0002] Before the extraction of leucine in the factory area, generally, pretreatment processes such as degreasing and impurity removal need to be carried out on raw materials such as animal hair. The pretreated raw materials then need to be further hydrolyzed, neutralized, and decolorized. Currently, during the processing of raw materials, due to the large amount of hair in the raw materials, problems such as entanglement are likely to occur during stirring, and hydrolysis is likely to be incomplete due to uneven heating; in addition, generally, neutralization and decolorization are completed in one-time processes, that is, single-time neutralization and decolorization. The raw materials after neutralization and decolorization are used as the feeding stock solution for subsequent leucine extraction. When the neutralization and decolorization are incomplete, the feeding stock solution needs to be recycled and re-injected into the neutralization tank or decolorization tank for secondary treatment. However, there is currently no equipment in the factory area that can perform secondary treatment on the feeding stock solution. Therefore, we improve the equipment to meet the usage requirements.
