Dingsheng Machine: Sunflower Seed Oil Extraction Process Unveiled for Enhanced Efficiency
Date:Oct 11th, 2024
Sunflowers, known for their beauty and resilience, are not just aesthetically pleasing but also a powerhouse of nutrition and oil. Sunflower seeds are not only used in food processing but also serve as a vital raw material for oil production—commonly known as sunflower seed oil. The process of extracting sunflower oil typically involves three main stages: pre-treatment, extraction, and refining, ensuring the production of high-quality, healthy, and safe edible oil. We will share you the sunflower seed oil extraction stage and provide insights into its key processes.
The Sunflower Seed Oil Extraction Process
The primary purpose of the sunflower seed oil extraction process is to extract oil from the sunflower seed meal by using a solvent capable of dissolving the oil. Through wetting and penetration, molecular diffusion, and convective diffusion, the oil is extracted from the raw material. The specific steps are as follows:
1. Sunflower Seed Oil Extraction: The sunflower seed meal is first delivered to the extractor using conveyor equipment. After the meal is subjected to solvent extraction, two components are obtained: a mixed oil containing solvent and a wet meal that still retains some solvent.
2. Desolventizing and Drying of Wet Meal: The wet meal discharged from the extractor contains a certain amount of solvent. To recover these solvents and obtain high-quality sunflower seed meal, a desolventizer is used for solvent removal and drying.
3. Mixed Oil Evaporation and Stripping: The mixed oil, which contains both oil and solvent, is then processed through evaporation and stripping to separate the solvent from the oil. This step uses equipment such as evaporators and stripping columns. Due to the difference in boiling points, the solvent and oil can be separated effectively using evaporation and stripping methods.
4. Solvent Vapor Condensation and Recovery: After the separation process, the solvent vapor from the wet meal and mixed oil is condensed and recovered. The recovered solvent can be reused in the process, reducing solvent loss and ultimately lowering sunflower oil production costs.
The sunflower seed oil extraction process is highly efficient, as it extracts most of the oil from the sunflower seed meal. After extraction, the residual oil content in the meal is minimal, which significantly increases sunflower oil yield and reduces oil loss.
Refining After Extraction
While the extraction process effectively removes most of the oil from the sunflower seed meal, the extracted sunflower oil still contains undesirable impurities such as gum-soluble substances, free fatty acids, pigments, and odor-causing compounds. To ensure the oil is safe for consumption, it must undergo a refining process that removes these impurities, making the oil fit for use in food products.
