Sunflower oil refinery machine is a special equipment used to process raw sunflower oil through a series of refining processes, aiming to remove impurities, free fatty acids, pigments, odors, etc. in the crude oil, improve the purity of the oil, and make it meet the standards for edible or industrial use. Modern sunflower oil refinery machines combine advanced automation control technology, energy-saving and environmentally friendly design and multifunctional technology, which can meet the needs of production enterprises of different sizes. The following will introduce the sunflower oil refinery machine in detail from multiple aspects such as its refining process flow, main equipment, technical characteristics, application scenarios and advantages.
1. Sunflower oil refinery process
Sunflower oil refinery is divided into two categories: physical refining and chemical refining. The specific process steps are as follows:
Degumming: Raw sunflower oil contains a certain amount of phospholipids and colloids, which will affect the transparency and stability of the oil. By adding an appropriate amount of water or acidic solution to react with the colloid in the oil, it is condensed into micelles and separated to ensure the clarity of the oil.
Deacidification: The free fatty acids in the crude oil will increase the acidity of the oil and affect its quality. The deacidification step usually removes free fatty acids through alkali refining (chemical method) or high-temperature distillation (physical method), reduces the acid value of the oil, and prolongs its shelf life.
Decolorization: Sunflower oil may contain some natural pigments, especially carotene and chlorophyll. The oil is treated with adsorbents such as activated clay or activated carbon to absorb the pigments, and finally the oil presents a clearer color.
Deodorization: During the pressing and refining process of sunflower oil, some volatile odor substances may remain. High-temperature vacuum distillation technology is used to remove the odor in the oil to ensure that the refined oil has a pure taste and a longer shelf life.
Filtration and polishing: Finally, the fine filtration system is used to further remove tiny particles and impurities to make the finished oil purer.
2. Main equipment of sunflower oil refinery machine
Degumming equipment: usually a horizontal stirring tank with a heating device and a stirring device inside, which is used to mix with water or acidic solution to condense and separate the colloid.
Deacidification equipment: including alkali refining tank and distillation tower. Alkali refining tanks are used for chemical deacidification, by adding alkaline solution to neutralize free fatty acids; distillation towers are used for physical deacidification, by evaporating free fatty acids at high temperature.
Decolorization equipment: Generally, it is a decolorization tank with heating and stirring functions, which can evenly mix oil and adsorbent to remove pigments in the oil.
Deodorization equipment: Common deodorization equipment is a high-temperature distillation tower, which can evaporate volatile odor substances in the oil under vacuum conditions.
Filtering equipment: Through plate and frame filters or other filtering equipment, the residual impurities in the oil are completely removed to ensure the purity of the oil.
3. Technical features of sunflower oil refinery machine
Automation control system: Modern sunflower oil refinery machines are equipped with PLC automation control systems, which can accurately control various process parameters (such as temperature, pressure, and time) during the refining process to ensure the stability and consistency of the refining process. Automated operation not only improves production efficiency, but also reduces errors in human operation.
Energy-saving and environmentally friendly design: Most equipment adopts energy-saving design, especially in the deodorization and decolorization processes, the waste heat is utilized through the heat recovery system to reduce energy consumption. The advanced environmental protection system can also effectively treat wastewater and waste gas in the production process, reduce pollution to the environment, and meet the environmental protection standards of modern enterprises.
Multiple process options: According to the quality and production requirements of crude oil, the equipment supports physical refining and chemical refining. For crude oil with high free fatty acid content, physical refining can be selected to remove free fatty acids by distillation; for low-quality crude oil, chemical refining can be used to remove impurities by alkali refining.
Efficient decolorization and deodorization: Through the use of adsorbents such as activated white clay, the equipment can remove natural pigments in the oil in a short time and improve the color quality of the oil. The efficient deodorization equipment can completely remove volatile odors through high-temperature steam to ensure the taste and quality of the refined oil.
Quality assurance of finished oil: The refining machine can ensure that the sunflower oil produced in the end has good taste, transparency and low acidity, while retaining the natural nutrients in the oil such as vitamin E, which improves the market competitiveness of the oil.
4. Advantages of sunflower oil refinery machine
High production efficiency: Automated equipment reduces the time of manual operation and increases production speed. The continuous production mode ensures a large production capacity and meets the needs of enterprises of different sizes.
Excellent quality of finished oil: The refining process strictly controls various process parameters to ensure the transparency, acidity and color of the oil, so that the final product meets the national edible oil standards.
Convenient operation and maintenance: The equipment has a reasonable structural design, simple operation and convenient maintenance, which can reduce the operation and maintenance costs of the enterprise.
Energy saving and environmental protection: The equipment achieves efficient use of energy through the energy recovery system during operation, which reduces the energy consumption of the factory. At the same time, the equipment meets environmental protection standards and reduces the emission of wastewater and exhaust gas.
5. Application scenarios of sunflower oil refinery machine
Small and medium-sized oil mills: Because the equipment has a high level of automation and convenient operation, it is suitable for the use of small and medium-sized oil mills, which can help enterprises improve production efficiency and reduce labor costs.
Large oil and fat processing plants: For large oil and fat processing plants, the equipment can achieve continuous production to ensure large-scale production needs. At the same time, its high-efficiency refining process can ensure the stability of oil quality in large-scale production.
Edible oil production enterprises: The equipment is mainly used to produce high-quality edible sunflower oil, which is suitable for edible oil processing and packaging enterprises, helping enterprises to produce high-quality products that meet market demand.
Industrial oil processing plants: Some refining equipment is also suitable for the production of non-edible industrial oils and fats. The refining process of sunflower oil can be extended to non-edible fields such as cosmetics and lubricants.
