At present, there are three main methods for digesting seaweed in the world: physical method, chemical method, and biological method. The physical method, also known as the mechanical crushing method, is to crush the seaweed into fine particles through physical means such as high-pressure grinding, freeze-thaw, cryogenic crushing, osmotic crushing, and ultrasound. In order to reduce the loss of active ingredients, high temperature and chemicals are avoided as much as possible during the whole process; the physical method mainly includes homogenization filtration, osmotic shock, ultrasonic crushing, grinding, high-pressure homogenization, and cryogenic crushing; among them, the cost of homogenization filtration is relatively low; but in the homogenization filtration method, the filter residue layer accumulated on the surface of the filter screen gradually thickens during the filtration process, and the resistance of the liquid through the filter residue layer increases accordingly, and the filtration speed decreases; when the filter chamber is full of filter residue or the filtration speed is too low, it is necessary to stop filtration, extract the suspension in the filter, remove the filter residue, replace the filter screen, and then filter again. Frequent filtration and replacement of the filter screen not only has low filtration efficiency and delays construction period, but also wastes the filter screen and increases costs.
