Problems solved by technology

However, grapefruit oil still contains a certain amount of wax, which will crystallize after a period of storage in the form of ribbons and a small amount of cloud. More and more, it affects the quality of the oil, and the two hydrocarbon-based carbon chains in the waxy molecules in the grapefruit oil are very long, which is prone to serious supercooling during the crystallization process, and when it reaches the freezing point, it is supersaturated. , while the tea polyphenols and catechins in the grapefruit oil are prone to supercooling, and are crystallized together with the supercooling phenomenon, resulting in a decrease in the nutritional value of the grapefruit oil

Embodiment 1

[0040] A method for physically squeezing mountain grapefruit oil includes the processes of screening, drying, crushing, steaming and frying, and hydraulically squeezing mountain grapefruit seeds to obtain crude oil, and then filtering the crude oil to obtain refined oil.

[0041] First put the grapefruit seeds in the flotation solution, and set the grapefruit seeds and the flotation solution to be centrifuged together for 15~30min, then select the grapefruit seeds that settle in the lower part of the flotation solution to complete the screening; the flotation solution consists of 1 mass part ~10 parts of sodium oleate are dissolved in 50~100 parts of water by mass. The mass parts of sodium oleate can be any value from 1 to 10 parts, such as 1 part, 2 parts, 5 parts, 6 parts, 8 parts, 10 parts, etc., and the mass parts of water can be any value from 50 to 100 parts. Values, such as 50 parts, 60 parts, 80 parts, 85 parts, 90 parts, 100 parts, etc., and the ratio of sodium oleate to...

Embodiment 2

[0046] Such as figure 1 As shown, the winterizer includes a accommodating portion 1 with a plurality of annular grooves 6 on the outer wall and a heat exchange plate 7. The heat exchange plate 7 is made of semiconductor material, which is the same as in the prior art to realize heating / cooling exchange through semiconductor materials. The structure and principle of the hot plate are the same; the middle of the accommodating part 1 is provided with a closed and hollow channel column 2, and the hollow of the channel column 2 can be used to hold the separating liquid, and the bottom wall of the channel column 2 is provided with a number of outflow holes 3 , There can be a flap at the orifice of the outflow hole. The flap can only be opened to the outside when the internal force is applied to cause the liquid / gas inside the channel column 2 to flow out without causing the liquid in the receiving part 1 Flow into the channel column 2, the flap is the same as the prior art; above the...

Embodiment 3

[0048] The steps of winterization are as follows: place the crude oil in figure 1 In the winterization device shown, after the temperature is reduced to a certain temperature, the grapefruit oil is dewaxed, decolorized, and recrystallized.

[0049] Step one (sub-division):

[0050] Methylpentane, sodium hydroxymethylcellulose and sodium hydroxide are added in a small amount of water to dissolve the sodium hydroxide in a molar ratio of 1:0.4:0.1, and then a mixed solution (separated liquid) is made.

[0051] Place the grapefruit oil to be processed in the accommodating part 1, turn on the air pump to continuously discharge the gas in the gas chamber 5 from the trachea 4, and then flow it into the channel column 2 according to the volume ratio of fractionated liquid: grapefruit oil 0.2:1 Add the fraction liquid, adjust the gas pump to keep the gas flow rate at 1-20 mL / min, make the fraction liquid enter the containing part 1 through the outflow hole 3 with the gas and react with the g...

Abstract

The invention discloses a physical squeezing method for preparing tea-oil tree seed oil and belongs to the field of oil squeezing. The method includes steps of: screening, drying and crushing tea-oiltree seeds, steam-stir-frying the tea-oil tree seeds, hydraulically squeezing the seeds to obtain an oil crude product; and filtering the oil crude product to make an oil finish product. The method isfree of soaking with organic solvents and is high in oil production ratio, and the oil finish product has a strong fragrance without any odor. The method, on the basis of not influencing the nutrients in the tea-oil tree seed oil, can remove the wax in the tea-oil tree seed oil well, so that the product is free of crystallization even after long time storage. The method can guarantee the qualityand the nutritional value of the physical-squeezed strong-fragrant tea-oil tree seed oil.

Description

Technical field [0001] The invention relates to a method for squeezing oil, in particular to a method for physically squeezing grapefruit oil. Background technique [0002] Mountain grapefruit oil is obtained from the seeds of the camellia oleifera tree of the camellia family. It has cool oil properties, sweet taste, rich in unsaturated fatty acids, and high nutritional value. It is called "Oriental Olive Oil". Grapefruit oil contains a physiologically active ingredient, squalene, which has good oxygen-enrichment capacity, can resist hypoxia and fatigue, and has the function of improving human immunity and enhancing the gastrointestinal tract. The survey found that the incidence of breast cancer, colon cancer, rectal cancer and other cancers among people who consumed camellia oil and olive oil for a long time was significantly lower than those who consumed other oils. The unsaturated fatty acids in grapefruit oil exceed olive oil. Olive oil contains 75% to 90% of unsaturated fa...
