The Oil That Presses Oil Machine To Squeeze Comes Out Is Not Clean, How To Do?

Pressing oil is to separate the oil from the raw material directly by physical pressure, the whole process without any chemical additives, to ensure product safety, health, no pollution, natural active nutrition is not destroyed. Pure natural nutrition, rich in oleic acid, linoleic acid, vitamin E, zinc, calcium and other nutrients needed by the human body, without cholesterol. Does not contain aflatoxin, the color shows the light yellow red, the fragrance is rich, the taste is pure.

 

Crude oil refers to unrefined pre-pressed or soaked vegetable oils (e.g., rural press, soil press, smelting, fire refining lard, etc.). Its main component is a mixture of triglycerides (commonly known as neutral oil); Also contain non - glycerine material, collectively referred to as impurities, according to the impurities in the oil dispersion state, roughly can be classified as three categories.

 

1. suspended impurities: including sediment, stock, powder and other solid impurities. The presence of these impurities is conducive to microbial activities, so that the oil is easy to hydrolyze rancidity, but not edible

 

2. Oil-soluble impurities: including free fatty acids, pigments, hydrocarbon waxes, aldehydes, ketones, etc., as well as trace metals and organic phosphorus, mercury, polycyclic aromatic hydrocarbons, aflatoxin caused by environmental pollution. The presence of these impurities is very harmful to the human body, some of the impurities are carcinogenic to the human body.

 

3. Water : the content of water in the crude oil is more, the existence of water makes the oil hydrolyze easily rancid

 

 

Refined oil refining refers to refined crude oil, crude oil to edible, storage and other harmful impurities to remove and get in line with the national quality standards of refined oil. There are three ways to refine crude oil:

1, mechanical method: including precipitation, filtration, centrifugal separation, mainly used to separate mechanical impurities suspended in the oil with some colloidal soluble impurities;

2, chemical method: mainly including acid refining, alkali refining, in addition, there are lipidization, oxidation, acid refining is treated with acid, mainly remove pigment, colloidal soluble impurities, alkali refining is treated with alkali, mainly remove free fatty acids, oxidation is mainly used for decolorization.

3, physical and chemical method: mainly including hydration, decolorization, steam distillation, hydration mainly remove phospholipid, decolorization mainly remove pigment, steam distillation for the removal of odor and free fatty acids.

Through refining, the water content, impurity, acid value and peroxide value in the oil reach the quality standard stipulated by the state, and it is not easy for rancidity to deteriorate, and favorable for storage.

 

 

Our company according to small and medium-sized oil processing enterprises design and production of small centrifugal oil filter, the use of high-speed rotating drum produced by the centrifugal force quickly rotating oil residue, water, oil stratification. The filtered oil is clear, no sediment, no foam, simple operation, strong practicality and other advantages, cost-effective than other oil filter equipment on the market.

 

Features of centrifugal oil filter:

 

1. Fast filtration speed, continuous filtration, each filtration "hydration" after the wool oil, dephosphorization, clarification effect is good, easy to operate.

 

2. Power saving. After the power supply starts up, clean oil can be filtered out after the drum reaches the normal speed for several minutes, saving time and power.
