Description

Technical Field

[0001] The utility model relates to the technical field of protein filtration and removal, in particular to a device for filtration and removal of protein in amino acid fermentation liquid. Background Art

[0002] In the amino acid production process, it is necessary to filter the large molecular proteins in the fermentation broth containing amino acids before a pure amino acid solution can be obtained. Currently, the existing filtration methods mostly use ceramic membrane equipment for filtration. The ceramic membrane is made of ceramic materials (aluminum oxide, zirconium oxide, titanium oxide, etc.) and has a separation function. Under the action of mechanical pressure, all components in the solution are forced to pass through the ceramic membrane. The amino acid molecules in the solution can pass through the ceramic membrane unimpeded. The large particle proteins in the solution cannot pass through the gaps in the ceramic membrane due to the interception effect of the ceramic membrane, thereby completing the filtration of the amino acid fermentation solution and the separation and purification of the amino acids. After long-term use of the ceramic membrane filtration equipment, the gaps on the ceramic membrane will be blocked by the large particle proteins in the fermentation broth, affecting the filtration effect of the ceramic membrane, so that the ceramic membrane needs to be cleaned after the ceramic membrane filtration equipment has been used for a period of time.

[0003] Chinese utility model patent application publication CN219518400U discloses a device for filtering and removing protein from amino acid fermentation broth. The device comprises a filter tank body and fixed plates spaced apart above and below the filter tank body, a ceramic membrane assembly disposed between the fixed plates, a raw material inlet pipe disposed at the top of the filter tank body, a filter outlet pipe disposed at the bottom of the filter tank body, and a filtrate pipe disposed on the side wall of the filter tank body, disposed between the two fixed plates.

This utility model improves the structure of the filter tank body, integrating traditional multi-pass filtration within a single filter tank body, effectively resolving the existing technical problem of large floor space requirements. Furthermore, this utility model has a simple structure, is easy to manufacture, and is suitable for large-scale deployment.
