Palm oil is the world's second largest edible vegetable oil. Palm oil refinery plays an inmprtant role in palm oil production line. In the palm oil processing plant, palm oil refining machine can be divided into intermittent palm oil refining machine, semi-continuous palm oil refining machine and fully continuous palm oil refining machine.

According to palm oil refining process, palm oil refining machine can be divided into palm oil chemical refining machine and palm oil physical refining machine.

According to palm oil refining processing capacity, palm oil refining machine can be divided into small 5-10 tons/day palm oil refining machine, medium-sized 20-50 tons/day palm oil refining machine, large-scale palm oil refining machine with a capacity of more than 100 tons/day.

According to material, there are general carbon steel plus stainless steel palm oil refining machine and all-stainless steel palm oil refining machine.

The purpose of palm oil refining machine in palm oil mill plant is to remove impurities, to achieve the finished product oil standard. 

 The Main Process of Palm Oil Refining Machine:

Crude palm oil ➞ degumming ➞ neutralization ➞ decoloration ➞deodorization➞ fractionation

 Crude oil filter: Buy back crude oil should be filtered suspended particles impurities and other impurities to the following production.

 Degumming: Pump crude palm oil in, stir quickly, and use direct steam or thermal oil to heat in a coil heater. It is necessary to control the amount of water added, the water temperature and the speed of adding water. During this period, the peptidic impurities will slowly turn into floc. Batch and semi-continuous palm oil refining machine use precipitation separation, while fully continuous palm oil refining machine requires a centrifugal separator.

 Deacidification: Add alkali to neutralize free fatty acids. Intermittent palm oil refining machine still uses the precipitation separation method, while semi-continuous refining and fully continuous palm oil refining equipment use the distillation method together with deodorization.

 Decolorization: Vacuum inhale a certain amount of decolorizing agent (activated clay/activated carbon), continue stirring and heating for 25 minutes, and then pump the mixture into the filter to separate the oil and decolorizing agent.

 Deodorization: Pump in the decolorized oil and heat it. When the oil temperature reaches above 100℃, direct steam is introduced to take away the odorous substances.

 The Main Components of Palm Oil Refining Machine:

 Neutralization pot: It is mainly used for acid refining, alkali refining or water washing of oil in oil refining equipment; (consumables, phosphoric acid or alkali, hot water)

 Decolorization pot: It needs to be filtered and bleached with white clay to remove colored impurities and pigments in oil;

 Deodorization pot: It is used to remove the odor of oil in oil refining equipment (made of stainless steel, with vacuum inside);

 Thermal oil furnace: It provides the heat energy required for production of oil refining equipment, and the temperature reaches 280℃;

 Vacuum pump: It provides the vacuum required for decolorization and deodorization, which can reach more than 755mmHg;

 Air compressor: It blows dry the decolorization white clay;

 Filter press: It filters the white clay;

 Steam generator: It generates steam required for deodorization distillation.

The crude oil by the palm oil press machine is refined by alkali, washed, decolorized and deodorized, and then it becomes the finished secondary salad oil, which can be filled after cooling.

 Process Characteristics of Complete Palm Oil Refinery Turnkey Project:

 Continuous alkali refining shortens the contact time between oil and alkali solution, reduces oil saponification, reduces refining consumption, and improves yield.

 Palm oil decolorization adopts a process combining premixing and steam stirring decolorization to improve decolorization efficiency, save white clay, simple and convenient operation, and negative pressure state prevents oxygen in the air from contacting hot oil, ensuring oil quality, inhibiting acid value recovery, and reducing peroxide value.

 Palm oil deodorization process uses a new type of continuous deodorization equipment, which is suitable for the deacidification and deodorization of vegetable oils with high acid value and low colloid content. Actual production has proved its obvious advantages: strong deacidification ability, good thermal decolorization effect, high refining rate, steam saving, good oil quality, etc.

 The palm oil refining process performs multiple heat exchanges, fully utilizes the system heat energy, effectively reduces steam consumption, and has the advantages of adjustable production process, flexible operation, high degree of automation, and good environmental hygiene.
