Experimental microfiltration membrane device for concentrating Dunaliella salina liquid

Abstract

Experimental microfiltration membrane equipment for concentrating a Dunaliella salina liquid is used for concentrating a Dunaliella salina liquid. The equipment comprises a microfiltration membrane, awater inlet pipe, a first ball valve, a pressure vacuum gauge, a diaphragm booster pump, a second ball valve, a third ball valve, a flowmeter and a water outlet pipe connected in sequence; the diaphragm booster pump is powered and the equipment is controlled to start and stop through the arrangement of a time relay and a power adapter. The time relay, the pressure vacuum gauge, the diaphragm booster pump, the power adapter and the second ball valve are fixed inside a distribution box, and the first ball valve, the third ball valve and the flowmeter are respectively fixed on different outer side walls of the distribution box. The invention has the beneficial effects as follows: the structure is simple; by setting the concentration time and controlling pre-pumping pressure of the diaphragmbooster pump, the pre-pumping pressure of the diaphragm booster pump is controlled to be 0.01 MPa and below; and after membrane filtration for concentration, the Dunaliella salina activity is kept good, and after late culture, various physiological indexes are not much different from physiological indexes of the original control group, and the concentration effect is ideal.

Description

technical field [0001] The invention relates to the technical field of biological cultivation and is used for concentrating salina algae liquid. Background technique [0002] Salina is a single-celled eukaryotic algae. It is rich in natural carotenoids, more than 70 kinds of minerals and trace elements that are needed for human health, such as anti-oxidation, anti-radiation and improving human immunity. The natural carotenoids contained in salina include not only all-trans β-carotene, but also 9-cis β-carotene, in addition to α-carotene, lutein, zeaxanthin, γ-carotene Su and so on. The carotenoids in salina have strong antioxidant effects, such as α-carotene is more than 10 times more antioxidant than β-carotene. Salina's element content ratio is consistent with the body fluid and cell plasma of the human body, which is very beneficial to help regulate the minerals in the human body from an unbalanced state to a balanced state. Salina products are extracted, concentrated...

AI Technical Summary

Problems solved by technology

The collection method of this salt algae has complicated process and high cost

And the solid-liquid separation is difficult, the drying device is added, and it is easy to cause the oxidation loss of β-carotene
