Embodiment Construction

[0006] (1) First select high-quality coconuts, peel and grind them to obtain coconut meat, dry them, and make particles of no less than 120 meshes, weigh them, put them into the extraction tank, and use a vacuum pump to exhaust the air in the container. The vacuum degree is -0.1MPa or less.

[0007] (2) Use the pressure difference to inject the extractant in the solvent tank: 1,1,1,2-tetrafluoroethane (R134a) into the extraction kettle, observe through the sight glass until the solvent is slightly submerged in the coconut raw material, and the material-solution ratio is controlled At 1:1-5.

[0008] (3) For the extraction of medium polar functional groups in the raw material, no extraction entrainer may be added in step (2).

[0009] (4) The extraction tank is heated by circulating hot water, the temperature is controlled between 20-80°C, and the pressure is controlled at 0.2-2.0MPa.

[0010] (5) After 30-180 minutes of extraction, the liquid mixed oil is released from the e...

Abstract

The invention relates to a sub-critical extraction process of coconut oil. Fresh and mature coconut meat serves as a raw material and sub-critical fluid serves as an extraction solvent to obtain natural coconut crude oil through sub-critical extraction and low-pressure analysis, the sub-critical fluid is used continuously after compression, and the crude oil is subjected to post-processing technologies such as filtration and decoloration to obtain high-quality edible-grade coconut oil. Monomers of several major products in the coconut oil can be extracted by using processes such as grading analysis to obtain coconut oil products with higher added values. The process is high in extraction ratio, the obtained coconut oil reserves all useful components of the natural coconut oil, residual extracting solvent after the analysis can be avoided, and the quality of the coconut oil is greatly improved compared with the existing process.

Description

technical field [0001] The invention relates to a process for extracting coconut oil. technical background [0002] Coconut belongs to the genus Cocos palmaceae. It is a typical tropical woody oil crop and food energy crop. Its comprehensive utilization has high economic value. At present, the utilization of coconut is mainly in the food and cosmetics industry, and the nutritional value of coconut has not been fully utilized. and economic benefits. Raw coconut oil, also known as "virgin coconut oil" or "natural coconut oil", is a pure coconut oil with a color as clear as water. It is a clear liquid at a temperature above 26°C and turns white when cooled. The "pearl" starts to solidify and becomes a white snow-like solid below 22°C. When coconut oil exists in a solid state, it can be used directly or melted before use. Coconut oil is rich in a large amount of medium-carbon chain fatty acid triglycerides, which is very suitable for patients with hepatobiliary and intestinal...
