Abstract
The invention discloses a cold-pressing method of linseed oil and belongs to a production method of edible oil. The cold-pressing method of the linseed oil comprises the following steps of: screening raw materials, pressing, filtering crude oil, hydrating and degumming, drying, grease-dewaxing and packaging. According to the cold-pressing method of the linseed oil, pure natural and pollution-free linseeds are used as raw materials, pressed at low temperature and precisely filtered. The cold-pressing method has the advantages of perfectly keeping the nutritional ingredients of the linseeds. Meanwhile, the cold-pressing method of the linseed oil completely adopts a physical way without any chemical reaction process, so that chemical residues appearing in a chemical refining process are avoided, and therefore, the cold-pressing method of the linseed oil is a green and healthy linseed oil processing method.
Description
Technical field:
The present invention relates to the production method of edible oil, particularly a kind of linseed oil method for cold pressing.
Background technology:
Flax (being commonly called as flax) is the traditional edible oil kind in NORTHWEST CHINA area, also is one of rare several oil crops of being rich in alpha-linolenic acid.Linseed oil oil-containing 38% ~ 42%, wherein alpha-linolenic acid content reaches about 57%, is typical ω-3 class edible oil.ω-the 3rd, essential fatty acid, human body can not self be synthetic, can only draw in food, so be the highest in the food through the content of the linseed oil ω-3 of cold press, the health of human body is played an important role.The U.S. food medication management council (FDA) determines that linseed oil is the heath food that is rich in alpha-linolenic acid, and confirms that it has in reducing blood-fat and hypotensive, prevent diabetes, anti-curing cancers, the cleaning blood objectionable impurities and prevents and treats 13 functions such as heart trouble.Simultaneously, linseed oil also contains multiple nutrients compositions such as protein, edible gum, VITAMIN, lignan, has very great development utility value.
The traditional hot moulding of China is squeeze after will oil crop seeds by using frying roasting, smell special fragrant, color is darker, output is higher but can destroy nutrition, is of low nutritive value.
And present cold pressing process more or less all can use chemical additive in process of production, thereby has chemical residue in the finished product.
Summary of the invention:
Given this, be necessary to allocate a kind of linseed oil method for cold pressing that adopts physics mode fully.
A kind of linseed oil method for cold pressing may further comprise the steps:
1. raw material screening: screen linseed oil with dressing machine, remove soil and other impurity, impurity content is reduced to below 1%.
2. go into to press: the continuous impouring oil equipment of the linseed oil after will screening keeps charging even continuously; Control out cake thickness at 3 ~ 4mm, go into to press 18 ~ 28 ℃ of temperature, the fuel-displaced position of the oil plant that oleaginousness is high major part concentrates on preceding pressure zone, the clarification of range estimation oil colours, and cake is solid to be circular-arc, and the cake face does not have oil stain and gets final product.
3. crude oil filters: will go up step expressed crude oil and inject plate filter, control pressure is at 2 ~ 3.5kg/cm2.
4. hydration degum: the crude oil after the filtration is squeezed into hydration tank, aquation when intensification reaches 60 ℃, adding concentration is 2 ~ 3% salt solution under 50 ~ 70 rev/mins stirring, and brine temp is identical with the oil temperature, stirs 25 ~ 35 minutes, when range estimation has the phosphatide particulate to separate with grease, reducing stirring velocity is 25 ~ 35 rev/mins, when the cohesion of range estimation phosphatide particle is obvious separations, stops stirring, the oil temperature keeps 60 ~ 70 ℃ at this moment, and precipitation will change next procedure over to after the unnecessary salt solution eliminating more than eight hours.
5. dry: in hydration tank, the thermal oil drying of the crude oil after coming unstuck is heated to 95 ~ 105 ℃, stirs 50 ~ 70 minutes, leaves standstill 10 ~ 12 hours.
6. oil and grease dewaxing: by cooling system with ethylene glycol at the cooling tank internal recycle, make the linseed oil crystallisation by cooling, in 16 hours with oily temperature drop to 2 ℃ above freezing, kept the oil temperature afterwards 2 ~ 3 hours, filter behind the growing the grain, then cooled linseed oil is moved to filter in the thermostatic tank again and obtain refining linseed oil.
7. packing: it is canned to select the dark glass bottle to carry out, and requires product lucifuge, secluding air after canned.
Preferably, step 3. in, keep the filter cloth device smooth.
Preferably, step 4. in, the phosphatide particulate is with before grease separates, stirring velocity is 60 rev/mins; The phosphatide particulate is with after grease separates, and stirring velocity is 30 rev/mins.
Linseed oil method for cold pressing of the present invention is to be raw material with pure natural, free of contamination linseed oil, adopts low temperature pressing, secondary filter, and its advantage is the nutritive ingredient that can perfectly keep former linseed oil; Simultaneously, this technology adopts physics mode fully, does not have any chemical reaction process, and the chemical residue of having avoided chemical refining to occur is a kind of green health linseed oil working method.
Embodiment:
