Dingsheng Machine Continuously Researches and Improves Dewaxing Technology for Sunflower Seed Oil, Committed to Providing Efficient and Reliable Solutions.

Date:Jun 12th, 2023
Sunflower seed oil is a nutritious and widely used plant oil. It contains a certain amount of wax, and the presence of wax can lower the quality and stability of sunflower seed oil. In the production process of sunflower seed oil, wax removal is an important technological step.

Wax removal process helps eliminate the wax content in sunflower seed oil, thus improving the quality and stability of the oil. Ding Sheng Machinery, as a company with expertise in this field, provides advanced processes and equipment to meet customer needs. Whether it's process design, equipment manufacturing, or after-sales service, Dingsheng Machine is capable of offering high-quality solutions and comprehensive support to customers.

The wax removal process of sunflower seed oil involves using sunflower seed oil wax removal equipment to eliminate the wax content in the oil, thus obtaining high-quality sunflower seed oil. Typically, crude sunflower seed oil contains wax in the range of approximately 0.06% to 0.2%. These waxes not only affect the transparency and taste of sunflower seed oil but also produce odors during cooking, which can have an impact on human health. Therefore, wax removal is an important step in the production process of sunflower seed oil.

After wax removal, the wax content in sunflower seed oil is completely eliminated, and the value of the oil is enhanced. That's why most customers choose to remove the wax from crude sunflower seed oil.

The wax removal process of sunflower seed oil generally involves the following steps: heating, heat exchange, cooling, crystallization, maturation, filtration, and heat exchange. The sunflower seed oil wax removal equipment used includes plate heat exchangers, crystallization tanks, plate and frame filter presses, and others. Let's take a detailed look at the process of sunflower seed oil wax removal.

The sunflower seed oil to be dewaxed is usually stored in a tank at a temperature below 30°C. At this temperature, some of the wax in the oil will crystallize and form solid particles. To ensure proper wax precipitation and crystallization during the dewaxing process, the sunflower seed oil needs to be heated first to dissolve the precipitated wax. Then, the oil temperature is lowered through a heat exchanger, and the crude oil is fed into the crystallization tank.

In the crystallization tank, the sunflower seed oil is cooled using cold water coils. To allow the wax to solidify into larger clumps while ensuring uniform cooling of the oil, gentle stirring is employed at a speed of around 10-15 r/min.

Once the sunflower seed oil has cooled to the specified temperature, stirring is stopped and maintained for a period of time to allow further crystallization of remaining wax and growth of small crystals. This process is called maturation and typically lasts for 12-16 hours.

The well-crystallized sunflower seed oil is then filtered using a plate and frame filter press to separate the oil from the wax, effectively removing the wax from the sunflower seed oil. The filtered sunflower seed oil is pumped into a plate heat exchanger for heat exchange with unwaxed oil before being stored, resulting in the final product oil.

This is the operational process of the sunflower seed oil wax removal. Due to variations in the wax content of crude sunflower seed oil and the desired quality of the final product oil as per customer requirements, various technical parameters during the wax removal process need to be adjusted and confirmed by engineers.
