Dingsheng Machine Innovates Sunflower Seed Oil Production Line to Meet Market Demand for High-Quality Oils

Date:Oct 7th, 2024
Currently, the majority of sunflower seed oil on the market is produced using the pre-press extraction process. The dehulling, pressing, and extraction process is the core technology of sunflower seed oil production lines. This method avoids excessive refining, high temperatures, and the effects of acids and alkalis, preserving the oil’s nutritional content as much as possible, ensuring that the oil remains high in quality.

Sunflower Seed Oil Production Process
First-Grade Sunflower Seed Oil Processing: The process begins by screening and washing the sunflower seeds to remove impurities. The seeds are then dehulled and crushed. After the hull is removed, the kernels are sent to the steam cooker for further processing, followed by pressing with an oil expeller. The extracted crude oil is then subjected to the solvent extraction process to obtain the raw oil. Finally, the oil undergoes a refining process that includes degumming, decoloring, neutralizing, and deodorizing to obtain high-quality, purified edible oil.

Sunflower Seed Oil Pressing Process
Step 1: Screening Select clean sunflower seeds with an oil content of 30-50%. Use cleaning screens and magnetic separators to remove impurities such as sediment, stones, and metal particles from the seeds.

Step 2: Dehulling and Crushing After dehulling, sunflower seeds are pressed to enhance production capacity and oil quality. After screening, the seeds are dehulled in a dehulling machine. Then, the seeds are crushed into a specific particle size using a grinding machine.

Step 3: Flaking and Steaming The pressing process begins by flaking the sunflower seeds into thin sheets. The purpose of this step is to break down the cellular structure, making it easier to extract the oil.

Step 4: Pre-Pressing and Extraction After pre-pressing, the oilcake is loose but not crushed, allowing for better solvent penetration during the extraction process. The combined pre-press and extraction process provides superior oil quality and economic efficiency compared to single pressing or extraction.

Sunflower Seed Oil Refining Process
The sunflower seed oil refining process consists of several key steps, including degumming, decolorizing, deodorizing, and dewaxing. Refined oil has a lighter color, higher nutritional value, and a better taste.

Sunflower Seed Oil Refining Equipment
The refining process requires a complete set of sunflower seed oil refining equipment. Key equipment includes:
  • Degumming, dephosphorization, and dehydration tanks
  • Decolorizing tanks
  • Soapstock tanks
  • Deodorizing tanks
  • Clay tanks
  • Crude oil tanks
  • Oil filter pumps
  • Vibrating filters
  • Air compressors
  • Heat exchangers
  • Thermal oil furnaces

Dewaxing Process
After deodorization, sunflower oil still contains a small amount of wax. This is sent to the pre-cooling crystallization tank, where it is cooled at a specific rate for 8 hours. The oil is then left to crystallize at a specific temperature in the crystallization tank for 12 hours. The oil and wax are separated using a filter press, and the dewaxed sunflower oil meets the high-grade edible oil standards.

Extraction Process
Pre-Press Extraction Process Features: Compared to other single oil extraction methods, the pre-press extraction process offers higher oil yields, better oil quality, improved economic benefits, strong adaptability to oilseeds, and flexible production. This process is also suitable for oilseeds such as peanuts, rapeseed, and sunflower seeds.

Refining Process Features
Continuous Refining Process: The continuous refining process can handle production capacities exceeding 50 tons per day. This process offers high refining yields and low auxiliary material consumption, meeting the requirements for deep processing of the final product. Continuous operation is required, making it ideal for large-scale production in continuous production enterprises.
