Clarificación del caldo de fermentación de ácido orgánico

Aunque actualmente se utilizan procesos por lotes, se han investigado una serie de técnicas más avanzadas para mejorar la eficiencia del proceso de fermentación de ácidos orgánicos. La promesa de todos los resultados debe haberse logrado utilizando la filtración de flujo tangencial en los sistemas de fermentación continua.

Una de las principales ventajas de la filtración de flujo tangencial es que las concentraciones más altas de biomasa son posibles porque las células se reciclan continuamente al fermentador. Una densa población de células no solo acelera la producción de ácido láctico sino que también minimiza la contaminación por microorganismos extraños. Por tanto, los sistemas continuos de alta densidad celular podrían aumentar la eficiencia de la producción de ácido láctico. También se puede aplicar a la producción de ácido nictric.

El caldo de fermentación de ácido láctico en el rendimiento principal de la incrustación de la membrana es

A. Gel de polarización ensuciamiento de la superficie de la membrana. Caldo de fermentación de ácido láctico por centrífuga filtros gruesos, a excepción de una pequeña cantidad de micelio y sólidos, pero también contiene una gran cantidad de proteínas, azúcar y material fácilmente carbonizado. Durante el proceso de filtración de membrana de la purificación del ácido láctico, estas sustancias se depositan fácilmente sobre la superficie de la membrana y se forma la formación de la polarización de gel.

B. Adsorción de poros de membrana, contaminación por cristalización. Agregar un exceso de carbonato de calcio es ajustar el pH del sistema, de esta manera, el exceso de carbonato de calcio se produce fácilmente cristalización dentro del orificio y en la superficie de la membrana. En la operación real, la tubería puede generar fácilmente una corta diferencia de temperatura debido a la solubilidad del lactato de calcio que es muy sensible a la temperatura, por lo que el lactato de calcio también es vulnerable a la superficie de precipitación o deposición dentro del orificio de la membrana y en la superficie de la membrana.

Para eliminar las impurezas,Membrana de cerámicaMecanismo de contaminación en el proceso de fermentación de ácido láctico se reduce a micelio, proteína, contaminación de polarización de azúcar y gel causada por el material carbonizado en la superficie de la membrana y la contaminación de cristalización del carbonato de calcio-lactato de calcio dentro del agujero y la superficie de la membrana. El procedimiento razonable de la membrana de limpieza es
