Problems solved by technology

The specific performance is as follows: (1) Due to the seasonality and regionality of tangerine peel crops, the traditional domestic direct consumption and rough processing mode can no longer meet the needs of consumers. Therefore, the refined tangerine peel oil with high content of functional components can improve The quality of the looming
(2) At present, there is no relevant high-quality tangerine peel oil product in the domestic and foreign markets
The mechanical pressing method has long pressing time, low oil yield, many impurities, and poor oil quality; the organic solvent extraction method has a series of problems such as long extraction time, low efficiency, large solvent consumption, and easy to cause solvent residue in the product; and The supercritical fluid extraction method has high requirements for equipment, complex process, small equipment volume, high cost, and high energy consumption, and is not suitable for large-scale industrial continuous production; Fluid Extraction of Seabuckthorn Seed Oil" (201110374434.4), using subcritical fluid extraction to extract seabuckthorn seed oil from seabuckthorn seeds, but there are problems such as long extraction time, large demand for extraction solvent, and continuous operation

Embodiment 1

[0026] Embodiment 1: a kind of method of continuous phase change extraction tangerine peel oil, comprises the following steps:

[0027] (1) Select high-quality tangerine peel after removing impurities, dry it at 50°C, control the moisture content to ≤15%, crush it to 60 mesh, and obtain the raw material of tangerine peel.

[0028] (2) Weigh 10kg of the treated tangerine peel raw material, put it into the extraction kettle of the continuous phase change extraction device, feed 25L of n-butane, and extract at 150L / h under the conditions of extraction temperature 45°C and extraction pressure 0.5Mpa The flow rate flows through the extraction kettle, and the extraction is continuous for 50min. After the orange peel oil is extracted, it flows into the analysis kettle, the analysis temperature is 75°C, and the analysis pressure is 0.1Mpa. It becomes liquid, flows through the extraction kettle, extracts the material again, and recycles it. The extracted tangerine peel oil is stored i...

Abstract

The invention provides a continuous phase-changed extraction method for orange peel oil. The method comprises the following steps of: placing dry crushed orange peel raw materials into an extraction kettle; compressing an extraction agent into a liquid under the condition that the pressure and the temperature are always lower than the critical pressure and the critical temperature of the extraction agent; enabling the extraction agent to flow through the extraction kettle at the flow speed of 100-150L / h under the conditions that the extraction temperature ranges from 35 DEG C to 55 DEG C, and the extraction pressure ranges from 0.5Mpa to 2Mpa, and continuously extracting for 50-120min; after the orange peel oil is extracted, enabling the extraction agent to flow into a liberation kettle for liberating at the temperature of 65-75 DEG C and the pressure of 0.1-0.4Mpa; heating and carrying out pressure-reduced phase change on the extraction agent to enable the extraction agent to become a gas, then, immediately condensing the gas to enable the gas to become a liquid, and enabling the liquid to flow through the extraction kettle for extracting the materials again; and circulating many times in such a way. The continuous phase-changed extraction method has the advantages of high supercritical extraction efficiency, no solvent residues in products and high aroma component retention rate; in addition, the extraction pressure and the liberation pressure are lower than the supercritical pressure and temperature; and meanwhile, the continuous phase-changed extraction method has the characteristics of large extraction volume, high mass handling capacity and low production cost of a conventional solvent.

Description

technical field [0001] The invention relates to a method for extracting vegetable oil, in particular, it provides a method for extracting tangerine peel oil. Background technique [0002] Chenpi is the ripe fruit peel of Rutaceae orange and its cultivars. Orange evergreen small trees or shrubs, cultivated in hills, low mountains, along rivers and lakes or plains. Distributed in various regions south of the Yangtze River. When the fruit is ripe from October to December, pick the fruit, peel off the peel, and dry in the shade or ventilated. As a traditional medicinal material and food material in my country, tangerine peel has a long history of medicinal and edible use. It has the functions of guiding cold evil in the chest, breaking stagnant qi, benefiting the spleen and stomach, lowering blood pressure, and lowering blood fat. It also has significant health care value and is well received by consumers. of favor. [0003] Although people have carried out extensive and in-d...
