Problems solved by technology

However, the oil-seed oil production technology in the oil industry is still pre-pressing-leaching to extract crude oil, and then using high-temperature degumming, deacidification, decolorization and deodorization to produce salad oil, and this over-processed product removes most of the functional activity. The fat accompanying substances such as natural vitamin E, phytosterols, squalene, polyphenols, β-carotene, etc., and unique flavor substances reduce the original nutritional value of vegetable oil; at the same time, high temperature and chemical treatment lead to energy consumption of vegetable oil production High, high refining consumption, but also easy to produce harmful substances such as chloropropanol esters, trans fatty acids, benzopyrene, etc., unable to produce real high-quality vegetable oil

Embodiment 1

[0043] Using rapeseed as raw material, firstly use screening and cleaning, the screened oilseeds are fed into the fluidized bed, and the pressurized gas is evenly transported into the fluidized bed through the air distribution plate with a certain pressure drop, so that the expansion ratio of the mixture of oilseed and impurities is 12. %, the medium with a specific gravity smaller than the oilseed is separated from the top of the fluidized bed, and the medium with a larger specific gravity than the oilseed is separated from the bottom of the fluidized bed, and the obtained rapeseed has an impurity content of 0.02%. The proportion of seeds is 0.01%. The separated rapeseed and dust-laden air enter the chamber-type high-pressure ion atomization device respectively, the atomization pressure is 15MPa, and the water mist droplets are 5μm. The rapeseed and dust-laden air are in different chambers, and the clean rapeseed and air are discharged respectively. . The clean rapeseed is i...

[0045] Using camellia seeds as raw material, firstly use screening and cleaning, the screened oil seeds are sent to the fluidized bed, and the pressurized gas is evenly transported into the fluidized bed through the air distribution plate with a certain pressure drop, so that the expansion ratio of the mixture of oil seeds and impurities is 5 %, the medium with a specific gravity smaller than the oilseed is separated from the top of the fluidized bed, and the medium with a larger specific gravity than the oilseed is separated from the bottom of the fluidized bed, and the obtained camellia seed has an impurity content of 0.2%. The proportion of seeds is 0.1%. The separated camellia seeds and dust-laden air enter the chamber-type high-pressure ion atomization device respectively, the atomization pressure is 5MPa, and the water mist droplets are 50μm, in which the camellia seeds and the dust-laden air are in different compartments, and the clean camellia seeds and air are discharg...

Embodiment 3

[0047] Using sesame as raw material, firstly use screening and cleaning, the screened oilseeds are fed into the fluidized bed, and the pressurized gas is evenly transported into the fluidized bed through the air distribution plate with a certain pressure drop, so that the expansion rate of the mixture of oilseeds and impurities is 8.5% , the medium with a specific gravity smaller than that of the oilseed is separated from the top of the fluidized bed, and the medium with a larger specific gravity than the oilseed is separated from the bottom of the fluidized bed. The impurity content of the obtained sesame is 0.11%. 0.05%. The separated sesame and dust-laden air enter the chamber-type high-pressure ion atomization device respectively. The atomization pressure is 10MPa, and the water mist droplets are 26μm. The sesame and dust-laden air are in different chambers, and clean sesame and air are discharged respectively. The clean sesame is fed into the fluidized bed group of the so...

Abstract

The invention discloses a method for high-efficiency preparation of vegetable oil. The method comprises: net selection of raw materials: sequentially screening, air-dense medium fluidized dry selection, high-pressure ion atomization to separate non-oilseed impurities and oilseed mold grains, shriveled grains, Raw sprouts; heat pump pre-conditioning: use solar heat pump system to pre-condition the oilseed after cleaning; solid-state radio frequency stabilized re-conditioning: use solid-state radio frequency stabilized device to pre-condition the oilseed Carry out reconditioning, the temperature of the oilseed after reconditioning is 130-170°C; anti-oxidative oil extraction: add ascorbic acid and 2-phenylchromanone derivatives to the reconditioned oilseeds and then press; oil refining : After the pressed oil is heated up to 40-55°C, the alcohol ester compound is added and separated by filtration. Beneficial effects of the present invention: the method of the present invention releases a large amount of endogenous active substances in oilseeds, more effectively retains nutrition and flavor through low-temperature refining, realizes the production of high-quality oils and fats, and can satisfy the processing of various oilseeds Production.

Description

technical field [0001] The invention relates to the technical field of oil processing, in particular to a method for efficiently preparing vegetable oil. Background technique [0002] my country is a big country in the production and consumption of edible vegetable oil. At present, the methods for preparing vegetable oil from oil plants in my country mainly include pre-pressing-leaching, one-time hot pressing, puffing, low-temperature pressing, and water-enzymatic production. However, the oil-to-oil technology in the oil industry is still pre-pressing-leaching to extract crude oil, and then using high-temperature degumming, deacidification, decolorization and deodorization to prepare salad oil, and most of the functionally active products are removed from this over-processed product. The fat concomitants such as natural vitamin E, phytosterols, squalene, polyphenols, β-carotene, etc., as well as special flavor substances, reduce the original nutritional value of vegetable oi...
