OIL REFINING MACHINE: the requirements of different raw materials: crushed peanut oil due to the use of purely physical compression method, to retain the original flavor of peanuts, so the requirements of peanut raw materials is very strict, raw materials require fresh, acid value, low peroxide value, and therefore the relative price high. At the same time because only the press, peanut cake in the residual oil high, press oil oil rate is relatively low, which is squeezing peanut oil prices are relatively high another reason.

OIL REFINING MACHINE: The chemical refining oil is a chemical oil method of oil from the oil separated from the oil. It is mainly used "No.6" solvent oil (No. 6 light gasoline) to soybean raw materials "soak", and then high temperature extraction, through the "six off" process (ie degreasing, degumming, dewaxing, decolorization, deodorization, deacidification) refining Come into being. This method of production of high oil prices, low cost, but there is no solvent in the solvent residue, therefore, the state of refined oil solvent residue has a strict requirement.
Read the above description, we have the difference between the press oil and refined oil have a better understanding of it, after the selection of edible oil can come in handy Oh!

OIL REFINING MACHINE: The difference between the crude oil and the refined oil presses In the initial crushing of oil crops, the oil produced and not filtered and other processes known as the crude oil, when the oil after filtration refining oil produced as refined oil, The two are very different, double as the oil press to do a more detailed description. Gluten oil is indicative of untreated pre-press or leaching of animal and vegetable oils (such as rural press, soil oil and smelting, fire lard, etc.).

OIL REFINING MACHINE: Its main component is a mixture of glycerol tri-fatty acids (commonly known as neutral oil); also contains non-glycerol substances, collectively referred to as impurities, according to the dispersion of impurities in the oil, can be summarized into four categories. 1, suspended impurities: including sediment, blank, powder and other solid impurities. 2, peptizing impurities: including phospholipids, proteins, carbohydrates, etc., of which the most important is the phospholipid, the presence of these impurities is not only easy to make oil and grease, but also the use of these impurities in the presence of these impurities, Hydrolyzed rancid, the appearance of opaque, but also in the cooking will produce a lot of foam and produce black precipitation; seriously affect the cooking, frying food color and flavor, but also lost the nutritional value of the oil itself, but also has a certain toxicity; Oil-soluble impurities: including free fatty acids, pigments, hydrocarbon waxes, aldehydes, ketones, etc., as well as trace metals and organic pollution caused by organic phosphorus, mercury, polycyclic aromatic hydrocarbons, aflatoxin and so on.
OIL REFINING MACHINE: The presence of these impurities is very harmful to the human body, some impurities on the human body also carcinogenic effect. 4, moisture: crude oil in the water content of more water, the existence of easy to make oil hydrolysis rancidity deterioration.

OIL REFINING MACHINE: Refining oil refers to the refining of crude oil, the oil in the food, storage and other harmful impurities to remove and get in line with national quality standards of refined oil. There are three methods of refining the crude oil: 1, mechanical method: including precipitation, filtration, centrifugal separation, mainly used to separate the suspended impurities in the mechanical impurities with some of the plastic impurities; 2, chemical: , Alkali refining, in addition, there are fat, oxidation, acid refining is the acid treatment, the main removal of pigments, peptizing impurities, alkali refining is alkali treatment, the main removal of free fatty acids, oxidation is mainly used for decolorization. 3, physical and chemical methods: mainly including hydration, decolorization, steam distillation, etc., the main removal of phospholipid hydration, decolorization mainly remove the pigment, steam distillation for the removal of odor substances and free fatty acids.

OIL REFINING MACHINE: Crude oil through refining, oil, water, impurities, acid value, peroxide value have reached the national quality standards, and not easy to rancidity deterioration, and favorable storage, cooking does not produce a lot of fumes, to maintain the oil flavor. Mountain Village Oil Food Co., Ltd. production of "mountain village" brand tea oil for refined pure tea oil.
