Abstract

The invention belongs to the technical field of fermentation liquor filtration and extraction, and particularly relates to a beta-carotene fermentation liquor filtration and extraction process and equipment, and the process comprises the following steps: filtering the fermentation liquor with a membrane to obtain a concentrated solution, carrying out top washing into an acidification tank, adding acid, then adding a sodium hydroxide solution to adjust the pH value to obtain an acidified neutralized solution, filtering the acidified neutralized solution with a high-pressure plate frame, and carrying out top washing with water, and discharging to obtain mycelia; and putting into a multifunctional extraction tank, adding an extraction solvent, pumping the extraction liquid into an extraction liquid tank, repeating the extraction operation, finally adding water into the extracted mycelia, recovering the extraction solvent, and conveying and collecting the mycelia. The equipment comprises a membrane filter, an acidification tank, a high-pressure plate frame filter and a multifunctional extraction tank which are sequentially connected, and the multifunctional extraction tank is connected with the extraction liquid tank and a spiral slag extractor. The process and equipment are effectively combined, the water content and impurities of mycelia are reduced after the fermentation liquor is filtered and extracted, efficient solid-liquid extraction is achieved, and the extraction yield and the solvent recovery rate are increased.

Description

technical field [0001] The invention belongs to the technical field of filtration and extraction of fermented liquid, and in particular relates to a filtration and extraction process and equipment for beta-carotene fermented liquid. Background technique [0002] In terms of fermentation broth filtration, plate and frame filtration is commonly used at present. The working process of plate and frame filtration is: the filtrate is pumped into each closed filter chamber of the filter machine, and under the action of working pressure, the filtrate passes through the filter membrane. Or other filter materials are discharged through the liquid outlet, and the filter residue is left in the frame to form a filter cake, so as to achieve the purpose of solid-liquid separation. Plate and frame filtration is more suitable for airtight filtration of liquids with lower viscosity and less slag content below 50% concentration to meet the requirements of fine and semi-fine filtration such as ...
