Description

Technical Field

[0001] The utility model relates to the technical field of amino acid production, and more specifically to a filtering device for producing amino acids. Background Art

[0002] Amino acids are the most basic substances that constitute biological proteins and are related to life activities. In the field of amino acid production, amino acids need to undergo fermentation, elution, filtration, concentration, product formation, and drying during the production process. Amino acids require bacterial fermentation to produce protein, which is then produced by protein hydrolysis. There are certain impurities in these processes. In order to ensure the purity of the amino acid concentration, the produced amino acid solution needs to be filtered.

[0003] After searching, the existing patent (publication number: CN204841174U) discloses a filtering device for amino acid production. When in use, the stirring shaft cooperates with the filtering layer, so that the amino acid solution is fully in contact with the filtering layer under the centrifugal action, and the filtering area is increased to achieve an ideal filtering effect; the setting of the filtering membrane and the activated carbon layer can double filter the amino acid solution, and the filtering effect is good; the setting of the return pipe can filter the amino acid solution multiple times, and the filtering is thorough, so as to ensure that a high-purity solution can be obtained in the end. However, the inventor found that the prior art has the following problems in the process of realizing the utility model: during the use of the above-mentioned filtering device, the sewage pipe can only be opened to discharge impurities after the filtering work is completed, and before the sewage is discharged, under the action of the stirring shaft, the impurities will adhere to the inner wall of the filtering layer under the action of centrifugal force.
