Edible oil refining production line
The edible oil refining production line is divided into batch type, semi-continuous type, and full-continuous type. The batch type mainly includes alkali refining pot, decolorizing pot, deodorizing pot, filter, vacuum pump and heat transfer oil furnace, etc.
The semi-continuous edible oil refining production line mainly includes alkali refining pot, degumming pot, decolorization pot or decolorization tower, filter, heat exchanger, deacidification and deodorization tower, shielded pump, vacuum system cooling water tower, heat transfer oil furnace, etc.
The main components of the continuous edible oil refining production line include oil transfer pump, mixer, heat exchanger, neutralization tank, centrifuge, drying tower, decolorization tower, vacuum system, deacidification tower, deodorization tower, refrigerator, Roots pump, shielding Pumps, water pumps, cooling towers, etc.
According to the different oil raw materials, it is equipped with dewaxing workshop, fractionation workshop, degreasing workshop, etc.
The function of the edible oil refining production line is to remove harmful impurities from the crude oil, to ensure that the color, transparency, taste, stability, fatty acid composition and nutritional components of the edible oil meet certain quality standards, which is essential in the edible oil production line of.
Crude oil → degumming → deacidification → decolorization → filtration → deodorization → filtration → fractionation/winterization/dewaxing (optional) → refined oil
Alkali refining pot in the edible oil refining production line: to remove impurities such as phospholipids and free fatty acids. Alkali refining pot, also called refining pot, is used for hydration degumming, neutralization and deacidification of oil. Alkali pan degumming firstly preheats the oil to 60-70°C, adds concentrated phosphoric acid of 0.05%-0.2% of the oil mass, mixes fully in the mixer, and stays in the temporary storage tank for a while, then adds 1%-5 % water for hydration, and then centrifuged, the oil is dehydrated and then decolorized with activated clay. Alkali deacidification is to add caustic soda to the alkali kettle to neutralize the free fatty acid to produce soap, and then separate the soap from the oil.
Decolorization pan in edible oil refining line: removal of pigment. The decolorizing pot first needs to add a decolorizing agent accounting for 1-3% of the oil weight (mainly clay), for physical adsorption, and then filter equipment to separate the oil from the decolorizing agent, so as to achieve the purpose of decolorizing.
Deodorization pot in the edible oil refining production line: removes the peculiar smell in the oil. Under a high temperature of 220-260°C and a certain vacuum condition, a certain amount of superheated steam needs to be introduced into the deodorization pot to strip the oil, and the purpose of deodorization is achieved according to the difference in the volatilization point of the oil and volatile small molecular substances. Because the temperature during deodorization will reach about 260 degrees, the carbon steel material of the deodorization pot may produce harmful substances at high temperature, so the deodorization pot of Dayang Company is made of stainless steel to ensure the quality of the refined oil.
Decolorization tower in edible oil refining production line
To remove the pigment in the oil, use mechanical stirring or gas stirring to fully mix the raw oil and the adsorbent to absorb the pigment in the raw oil, and then filter and separate the adsorbent that has absorbed the pigment through a filter to achieve the purpose of removing the pigment.
Centrifuge in edible oil refining production line
Remove the saponins in the oil, separate the grease and water, the raw crude oil is mixed with acid or alkali, fully mixed with a mixer, and after full reaction, a certain amount of saponins or colloidal substances are formed, which need to be separated by a centrifuge. The oil after washing needs to separate the excess water.
Heat exchanger in edible oil refining production line
The point heat exchanger is a necessary product part in the refining production line. During the refining process, the temperature of the oil needs to be adjusted many times to meet the needs of each section. Therefore, the entire production line needs a heat exchanger to adjust the temperature. According to the equipment Working principle, we have also designed in key places, waste heat utilization, heat exchange, so that the energy utilization in the system can be maximized.
Filters in edible oil refining machines: remove impurities and decolorizing agents from oils and fats.
Deodorization tower and deacidification tower in edible oil refining production line
Removes odor and free fatty acids from oil. In the high vacuum state, the odor or free fatty acid is used, and the evaporation temperature is lower than that of triglyceride, so that the odor or free fatty acid is separated to achieve the purpose of refining edible oil. Of course, free fatty acids can be sold after recovery.
Vacuum pump: create a negative pressure vacuum environment for the decolorization pot and deodorization pot.
Heat conduction oil furnace: provide heat source in the system
Refrigerator; to provide cooling needs in the system
In order to meet the needs of customers with different processing volumes, Dayang Company can provide you with 1-20 tons/day batch edible oil refining production line, 10-50 tons/day edible oil semi-continuous refining production line and 50 tons/day above full continuous edible oil refining line There are three types of refining lines. Of course, these three types of edible oil refining equipment have their own advantages, and you can choose one according to your specific needs.
Batch cooking oil refining production line: simple and flexible operation, low investment, suitable for frequent replacement of various oils, suitable for manufacturers with small processing volume.
Semi-continuous edible oil refining production line: The degumming and decolorization section is intermittent production, or decolorization can be continuous. The deacidification and deodorization section adopts deodorization tower process for continuous production, which can realize semi-continuous refining, high efficiency, energy saving, economy, and high additional output value. .
Fully continuous edible oil refining production line: It can realize continuous and uninterrupted production of all sections, with low production consumption, low oil loss, and more stable refined oil quality. For the deacidification and deodorization section of continuous refining, choose a single tower, or choose a double tower coupled production process
According to the type of crude oil and the size of the processing volume, the engineers of Ocean Oil can customize a set of edible oil refining machine for you. Conventional refining process production line, special production line for refining edible oil that is easy to reverse color, high acid value edible oil refining production line, etc.
For more than ten years, Dayang Oils has been adhering to the business philosophy of "quality first, integrity first". The edible oil equipment has reliable quality and has been exported to more than 90 countries and regions abroad. It is committed to redefining "intelligent manufacturing in China" with first-class technical products Connotation.
