Dingsheng Machine Introduces Advanced Walnut Oil Production Line Technology

Date:Sep 16th, 2024
Dingsheng Machine is excited to introduce its comprehensive walnut oil production line, designed to meet the demand for high-quality walnut oil, often referred to as the "Oriental Olive Oil" in international markets. Walnut oil is derived from walnut kernels, which have an oil content of 65% to 70%, making it one of the richest oil sources among tree nuts. The oil is yellow to brown in color and is considered an ideal edible plant oil.

Our walnut oil production line features a series of advanced equipment and processes to extract and refine pure, high-grade walnut oil. The process includes cleaning, crushing, de-shelling, roasting, pressing, solvent extraction, dewaxing, deodorization, and refining.

Key Equipment and Processes in the Walnut Oil Production Line:

1. Walnut De-Shelling Machine:
This essential equipment separates the walnut shell from the kernel. After screening, walnuts are placed in the de-shelling machine, which integrates both de-shelling and shell washing. The machine uses high-speed rotating blades to cut the outer shell, while any remaining shells are removed with steel brushes. The shelled walnuts are then washed to remove surface residue.

2. Walnut Oil Refining Process:
Filtered walnut oil undergoes deep refinement to enhance its quality. The refining process includes degumming, deacidification, decolorization, and deodorization, effectively removing impurities and harmful substances, resulting in high-quality, healthy walnut oil.

3. Alkali Refining Process:
The oil is heated to around 60°C, and an alkali solution (20-30 Bé) is added gradually over 5-10 minutes. The oil is stirred at a speed of 60 rpm for 5-10 minutes, forming soap particles that start to separate. The temperature is then slowly increased while stirring at a slower pace, with the oil reaching 65°C. At this stage, the oil and soap separate clearly. Stirring is stopped, and the soap solution is left to settle, a process that typically takes 4 hours, with full separation after 6 hours.

Dingsheng Machine provides complete walnut oil production lines, tailored to the needs of large-scale walnut oil processing plants. We also offer turnkey project solutions to streamline the entire process, ensuring high-efficiency production and exceptional product quality.
