Embodiment 1

[0064] like figure 1 As shown, get 1000KG harvested microalgae 1 (Pavlova viridis), with a moisture content of 90%, and use a high-pressure homogenizer 100 to homogenize once at room temperature (20° C.) with a homogenizing pressure of 20 MPa. Reach more than 95% microalgae wall breaking rate. The method has high wall breaking rate, simple production equipment, large-scale production, low production cost and short cycle.

[0065] The material after microalgae 1 breaks into 2m 3 The extraction kettle 200, and add 300KG extractant (fatty acid methanol 210), extract the microalgae oil under stirring. Parameters such as the amount of extractant, temperature, and time have a significant impact on the yield of microalgae oil. In the extraction operation, the extraction temperature was 70° C., and the extraction time was 4 hours. The ratio of material to extractant is set to 1:0.2-0.5.

[0066] Since the residue after breaking the wall of microalgae is only a few microns, and th...

Abstract

A production method for comprehensively utilizing oil-containing microalgae, comprising: using a high-pressure homogenizer to homogenize and break the wall of the microalgae at room temperature and high pressure. Transfer to the extraction tank, extract the microalgae oil under agitation, separate the liquid phase and the solid phase after centrifugation, wash the solid phase with water three times, add it to a spray dryer for drying to obtain microalgae powder. The liquid phase and the three times of washing liquid are added to the oil-water separator to separate into an oil phase and a water phase, and the oil phase is microalgae oil. The separated water phase is separated and purified to extract bioactive substances such as microalgae protein, microalgae polysaccharide, and microalgae liquid fertilizer. The invention has the advantages of low investment, simple operation, large-scale utilization of microalgae production method, and can produce microalgae oil, EPA, DHA, microalgae powder, microalgae protein, microalgae polysaccharide, microalgae liquid fertilizer and other high added value Semi-finished products.

Description

technical field [0001] The invention belongs to the technical field of bioengineering, and the invention relates to a method for utilizing microalgae, in particular to a production method for comprehensively utilizing oily microalgae, especially a "DHA" supercritical extraction method for oily microalgae. Background technique [0002] Microalgae are a kind of primitive and very important marine and aquatic biological resources, rich in fat, protein, polysaccharide, astaxanthin, vitamins, minerals, chlorophyll, β-carotene and other biologically active substances, and have fast growth The use of microalgae to obtain high-value active substances has become one of the research hotspots in various countries. [0003] According to the source microalgae are divided into: freshwater microalgae, salty lake water microalgae, seawater microalgae, etc.; according to the structure microalgae are divided into: spirulina, unicellular green algae, etc. Among them, oil-containing microalgae...
