Embodiment 1

[0014] Step 1: Optimizing the grape seeds, washing them with water to remove impurities and soil, drying the washed grape seeds, and putting them into the drying equipment to ensure that the drying temperature in the drying room is between 66°C and the drying time After 6 hours, the moisture content is less than 7%, and the dried grape seeds are pulverized by crushing equipment to obtain 38-mesh grape seed fragments, which are set aside;

[0015] Put 360kg of grape seed fragments into the extraction kettle and start the extraction. The extraction temperature is 39°C, the extraction pressure is 27Mpa, and the extraction time is 135min. Close the extractor, check to ensure that it is tightly sealed, and use a high-pressure pump to remove the liquid CO2 in the storage tank. Pump into the vaporizer, gasify into a critical fluid state, and then enter the extractor to extract the grape seed fragments. Set the pressure in the extractor to 14Mpa and the temperature to 34°C. The mixed f...

Embodiment 2

[0019] Step 1: Optimizing the grape seeds, washing them with water to remove impurities and soil, drying the washed grape seeds, and putting them into the drying equipment to ensure that the drying temperature in the drying room is between 50°C and the drying time After 6 hours, the moisture content is less than 7%, and the dried grape seeds are pulverized by crushing equipment to obtain 39 mesh grape seed fragments, which are set aside;

[0020] Put 360kg of grape seed fragments into the extraction kettle and start the extraction. The extraction temperature is 47°C, the extraction pressure is 27Mpa, and the extraction time is 143min. Close the extractor, check to ensure that it is tightly sealed, and use a high-pressure pump to remove the liquid CO2 in the storage tank. Pump into the vaporizer, gasify into a critical fluid state, and then enter the extractor to extract the grape seed fragments. Set the pressure in the extractor to 13Mpa and the temperature to 34°C. The mixed f...

Abstract

A supercritical extraction method of grape seed oil adopts cleaning, drying, crushing, supercritical extraction and molecular distillation, so the operating temperature is low, the heating time is short, and oil oxidation and rancidity induced by high temperature can be avoided, and the separation degree and the product yield are high; and molecular distillation also can reduce the acid value of oil, so efficient extraction, separation, no impurities and high purity of the extraction product are realized. The method has the advantages of simple operating technology, short extraction time, cost reduction and production efficiency improvement.

Description

technical field [0001] The invention relates to a method for extracting grape seed oil, in particular to a supercritical extraction method for grape seed oil. Background technique [0002] Grape seed is a by-product of wine making. If it is not utilized, it will not only pollute the environment, but also waste resources, because grape seed also contains 13% to 15% of oil, and the content of unsaturated fatty acids in grape seed oil Up to 90%, of which the linoleic acid content is as high as 80%, comparable to safflower oil. Linoleic acid is an important raw material for the synthesis of tetraoleic acid, and it has the functions of preventing thrombosis and dilating blood vessels. In addition, grapeseed oil is also rich in physiological oily components, which makes it have some physiological functions different from ordinary edible oils. Such as lowering blood pressure, clearing cholesterol, nourishing brain cells, etc. Now, it can be used as a specific nutritional health ...
