Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and the embodiments given in the accompanying drawings. The production technique of the present invention is easy to implement for those skilled in the art.

[0019] Referring to Fig. 1, get 1000Kg harvested green Pavlova, with a moisture content of 90%, and after homogenizing once with a homogenizing pressure of 20MPa with a high-pressure homogenizer at room temperature, a wall breaking rate of more than 95% is achieved. The material after breaking the wall enters 2m 3 The extraction kettle, and add 300Kg fatty acid methyl ester, extract microalgae oil under stirring state, extraction temperature is 70 ℃, and extraction time is 4 hours.

[0020] The extracted material was separated from liquid to solid by a horizontal spiral centrifuge, and the separated solid phase was washed with water three times, then added to a spray dryer for drying to obtain 16Kg of microalgae po...

Abstract

The invention relates to the filed of microalgae utilization engineering, in particular to a production method for fully utilizing oleaginous microalgae. The method is characterized in that the wall of the microalgae is broken by a high-pressure homogenization method, and the solid phase and liquid phase are separated out by an extraction kettle and a horizontal spiral centrifuge, and microalgae powder is made from the solid phase by a spray dryer. An oil phase and a water phase are separated from the liquid phase by an oil-water separator, and the oil phase is microalgae oil. A solid phase and a liquid phase are separated from the water phase by a vacuum concentration kettle, a salting-out kettle and a high-speed centrifugal filter, and microalgae protein is made from the solid phase by a freeze dryer or a spray dryer. A solid phase and a liquid phase are separated from the liquid phase by an alcohol precipitation kettle and the high-speed centrifugal filter, and microalgae polysaccharide is made from the solid phase by the freeze dryer or the spray dryer, and ethanol and microalgae liquid fertilizer are made from the liquid phase by an ethanol recovery tower. The invention is a good production method which requires low investment, has simple operation and can comprehensively use microalgae on a large scale, and can produce semi-finished products with high added value, such as the microalgae oil, the microalgae powder, the microalgae protein, microalgae polysaccharide, the microalgae liquid fertilizer, etc.

Description

[technical field] [0001] The invention relates to the field of microalgae utilization engineering, in particular to a production method for fully utilizing 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] The unsaturated fatty acids contained in microalgae fat (oil) are not only important components of higher animal cells, but also have special preventive and therapeutic effects on cardiovascular diseases. Anti-inflammation, immune regulation, anti-allergic, anti-tumor and anti-tumor effects, among which eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are particularly prominent. In th...
