An oil production line is a series of processes and equipment designed to extract and refine oil from various sources such as seeds, nuts or fruits. Here is an overview of the main stages involved in a typical oil production line:
1. Raw material preparation and cleaning
Receiving and Storage: Raw materials such as seeds or nuts are received and stored in large silos or bins.
Cleaning: Cleaning the raw materials to remove impurities such as stones, dirt and other foreign matter. This is usually done using sieves, magnets and de-stoners.
2. Crushing and shelling
Crushing: crush the cleaned raw materials into smaller pieces to facilitate oil extraction.
Dehulling: Removing the husks from the crushed material. This can be done by suction, where the lighter husks are blown away, or using sieves and gravity tables.
3. Tempering and peeling
Conditioning: The hulled material is heated to soften it and make it easier to extract the oil. This process takes place in a conditioning vessel.
Flaking: The conditioned material is passed through rollers to form flakes, thereby increasing the surface area for oil extraction.
4. Extraction
Solvent extraction: The flakes are treated with a solvent (usually hexane) to dissolve the oil. The mixture is then separated and the solvent is recovered and reused.
Mechanical Extraction: Alternatively, the oil can be extracted mechanically using an expeller press, but this method is less efficient than solvent extraction.
5. Desolventization
The oil and solvent mixture (mixed oil) are separated and the solvent is evaporated from the oil. The flakes are also desolventized to remove any residual solvent.
6. Degumming
Crude oil is treated with water or steam to remove phospholipids, which form gums that affect the quality and stability of the oil.
7. Neutralization
The degummed oil is neutralized with alkali (usually caustic soda) to remove free fatty acids and obtain neutral oil and soapstock.
8. Bleach
The neutralized oil is treated with bleaching earth or activated carbon to remove pigments and impurities and improve the color and quality of the oil.
9. Deodorization
The bleached oil is heated under vacuum to remove volatile compounds that cause odor and taste. This step produces a refined, odorless, tasteless oil.
10. Winterization (optional)
Winterization is an optional step in which the oil is cooled and filtered to remove waxes that can cause cloudiness at low temperatures. This is important for oils used in salad dressings and other products that need to remain clear when refrigerated.
11. Packaging
The refined oil is then filtered and packaged into bottles or other containers for distribution and sale.
12. By-products
Byproducts of oil production include meal or cake, a high-protein animal feed, and lecithin, used as an emulsifier in food.
Advantages of modern oil production lines
High Efficiency, High Yield: Advanced extraction and refining technologies maximize oil yield and quality.
Automation: A high level of automation reduces labor costs and improves consistency in production.
Environmental sustainability: Modern production lines incorporate solvent recovery systems and waste treatment facilities to minimize environmental impact.
Flexibility: The equipment can be adapted to process different types of raw materials, including soybeans, sunflower seeds, peanuts, etc.
Quality Assurance: A multi-step refining process ensures the production of high quality, safe, pure oil.
Efficient oil production lines are essential to produce high-quality oil at a competitive cost, meet market demands, and ensure sustainability of production practices.
The oil production line has a wide range of applications and can meet the needs of oil production of different types and scales. The main application scope of the oil production line is as follows:
1. Edible oil production enterprises
Large-scale industrial production: Large-scale edible oil production companies usually use fully automatic oil production lines to meet the high market demand for edible oil.
Small and medium-sized production enterprises: Small and medium-sized edible oil production enterprises can configure production lines of appropriate sizes as needed and carry out medium-scale production.
2. Agricultural cooperatives and farms
Agricultural product processing: Agricultural cooperatives and farms can use oil production lines to process their own oil crops (such as soybeans, sunflower seeds, rapeseed, etc.) to increase the added value of agricultural products.
Regional production: Some regional farms can meet the local market demand for edible oil through oil production lines and promote local economic development.
3. Oil processing plant
Processing of various oils: Oil processing plants can not only process common vegetable oils such as soybean oil, sunflower oil, rapeseed oil, etc., but also produce other types of vegetable oils such as peanut oil, palm oil, coconut oil, etc. by properly adjusting equipment and processes.
4. Food processing plants
Ingredient supply: Food processing plants can use oil production lines to produce high-quality vegetable oil as an important ingredient in the food production process to meet their own production needs.
5. Biodiesel production
Bioenergy: Vegetable oil is also an important raw material for biodiesel production. Biodiesel production companies can use oil production lines to provide a stable supply of raw materials for biodiesel production.
6. Overseas Market
Export processing: The oil production line can serve export processing enterprises and export the produced vegetable oil to other countries and regions to meet the needs of the international market.
7. Scientific Research Institutions
Technical research: Scientific research institutions can use oil and fat production lines to research and develop oil and fat processing technology, explore new processes and technologies, and improve production efficiency and product quality.
8. Other related industries
Feed production: The by-products produced during the oil production process (such as oil cakes and oil meals) are a high-protein, high-quality feed that feed manufacturers can use to produce feed.
Cosmetics and Pharmaceuticals: Vegetable oils and their by-products (such as lecithin) are widely used in the cosmetics and pharmaceutical industries. Companies in these industries can use oil production lines to produce raw materials.
The application range of oil production line is very wide, covering various fields from large-scale industrial production to small and medium-sized enterprise production, agricultural cooperative processing, food and biodiesel production, etc. Whether it is the domestic market or the international market, oil production line can provide efficient and reliable solutions to meet the needs of different customers.
