A 5TPD (5 tons per day) palm oil refining and fractionation production line is the core facility of small and medium-sized palm oil processing plant. It is mainly used to refine crude palm oil (CPO) into edible grade palm oil and produce palm oil products with different melting points (such as palm olein and palm stearin) through palm oil fractionation process. The following is a detailed introduction of the production line:
1. Main process of the palm oil refining production line:
(1) Refining process
The purpose of the palm oil refining process is to remove impurities in crude palm oil so that it meets edible standards. It mainly includes the following steps:
Degumming: remove phospholipids and gum.
Deacidification: remove free fatty acids through alkali refining or physical refining.
Decolorization: use activated white clay to adsorb pigments and impurities.
Deodorization: remove odors and volatile substances through high-temperature distillation.
(2) Fractionation process
The purpose of the palm oil fractionation process is to separate the refined palm oil into components with different melting points, which are mainly divided into:
Palm olein: has a low melting point and is suitable for use as cooking oil.
Palm stearin: has a high melting point and is used for food processing or industrial purposes.
Palm oil fractionation usually adopts dry fractionation or solvent fractionation. Dry fractionation is more common because its equipment is simple and environmentally friendly.
2. Main equipment of palm oil refining production line:
(1) Refining equipment
Degumming tank: used to remove gum.
Deacidification tank: used for alkali refining or physical deacidification.
Decolorization tank: equipped with agitator and clay addition system.
Deodorization tower: used for high-temperature distillation deodorization.
Filter equipment: used to separate clay and impurities.
Heat exchanger: used to heat and cool oil.
(2) Extraction equipment
Crystallization tank: used to control the cooling and crystallization of palm oil.
Maturing tank: promotes crystal growth.
Filter: used to separate liquid oil and stearin (common equipment is plate and frame filter or membrane filter).
(3) Auxiliary equipment
Boiler: provides steam.
Cooling water system: used for cooling.
Oil storage tank: used to store crude oil and finished oil.
Control system: PLC or DCS automatic control system.
3. Features of the palm oil refining production line:
Capacity: 5 tons of crude palm oil can be processed per day, suitable for small and medium-sized processing plants.
Automation: Semi-automatic or fully automatic control system can be selected according to demand.
Flexibility: The palm oil refining and fractionation process can be adjusted according to market demand to produce products of different specifications.
Environmental protection: Modern palm oil production lines are usually equipped with wastewater treatment and waste gas recovery systems to meet environmental protection requirements.
4. Advantages of the production line:
High efficiency and energy saving: Advanced heat exchangers and energy-saving equipment are used to reduce energy consumption.
High product quality: Refined palm oil meets international edible standards, and fractionation products can meet diversified needs.
Strong adaptability: Suitable for small and medium-sized processing plants, with a short investment return cycle.
5. Summary
A 5TPD palm oil refining and fractionation production line is an ideal choice for small and medium-sized palm oil processing plants, with moderate investment, mature technology and diversified products. Through reasonable equipment selection and process optimization, efficient and environmentally friendly production can be achieved to meet market demand.
