Title:
HOLLOW FIBER MEMBRANE, MANUFACTURING METHOD OF HOLLOW FIBER MEMBRANE, AND PRODUCTION METHOD OF BEER, WINE OR JAPANESE SAKE USING HOLLOW FIBER MEMBRANE
Document Type and Number:
Japanese Patent JP2019130522
Kind Code:
A
Abstract:
To provide a hollow fiber membrane hardly generating clogging during filtration of fermentation liquid such as beer, wine or soy sauce, and excellent in recoverability of membrane performance, and further in its persistence.SOLUTION: A hollow fiber membrane, which is a hollow fiber membrane for fermentation liquid filtration, includes a fluororesin-based hydrophobic polymer, and at least a hydrophilic macromolecule. In the hollow fiber membrane, the hydrophilic macromolecule contains a copolymer constituted of two or more kinds of monomer units, and hydration energy density of the hydrophilic macromolecule calculated based on following formula (1) is 40 to 70 cal-mol-1 Å-3.SELECTED DRAWING: None
