Dewaxing Rice Bran Oil: All You Need to Know elephantjournal.com/2023/10/dewaxing-rice-bran-oil-all-you-need-to-know October 31, 2023
The majority of us are unaware of the hidden steps involved in producing the food we consume. There are numerous procedures involved in producing everything that enters our kitchens, not simply food items. That also holds true for oil containers, whether they contain soybean, rice bran, or sunflower oil. We’ll talk about a technique for removing impurities, distilling, and creating digestible oil today. Dewaxing is the name of the procedure that is crucial in the processing of all types of oils. Come, let’s delve into it! What Is Dewaxing? As the name suggests, dewaxing is a process by which wax compounds that are present within cooking oils are filtered and removed. Most oils will have some degree of wax in them, but rice bran oil and sunflower oil have it in significant quantities. This is why dewaxing for RBO is going to be a major sector of the oil industry, as people’s consumption of the oil increases over time. If you want to know what this wax comprises, it is mainly triglycerides and results in the oil getting a hazy look during winter. Without dewaxing, the wax in the oil will turn solid at room temperature, which will make the oil look hazy. Through dewaxing, these compounds are separated from the rest of the oil, and clear oil is gained as a final product, which makes it to your tables. What Are the Steps Involved in Dewaxing Rice Bran Oil? You should be aware that the appropriate machinery and equipment must be built in order to obtain the required certificates and clearances if you plan to establish a rice bran oil factory in India. The procedure includes the following critical steps, among others: During the first step in dewaxing for RBO, the crude oil mixture is bleached to decrease the phosphorus and moisture content in the oil to the minimum amount possible. Next, the oil has to be heated up to the requisite temperature, so it becomes completely liquid. This step is important and must be performed in temperature-controlled vessels for maximum accuracy.

The next part of the process is to cool the liquid oil mixture down to 10-15°C, which is about the freezing temperature for wax. Once this temperature is reached, the wax will naturally float on top, while the oil will remain liquid. Technically, the dewaxing process is done at this stage, but for food-grade oil, some additional steps need to be performed. Pilot plants can make use of a slow-speed mechanical agitator and insulated crystallizer, so all the wax sediments slowly come up to the surface, and any micro-blends are separated as well. When the oil crystallizes after several hours, it is deemed ready for filtration. The slurry is then pumped through pipes and filtered of all the excess wax and compounds, leaving behind clear oil in the process. Why Go for A Rice Bran Oil Factory in India? As a company or individual businessman looking for an opportunity to capitalize on that will yield dividends for years to come, getting into edible oils is extremely safe and profitable. Think about it! Edible oils are a necessary part of the food chain, and they are going nowhere! Edible oils will always remain in demand, and so will your business! So, if you want to build a rice bran oil factory in India, make sure to contact Mectech. Mectech is a global company with international offices on every continent. With decades of experience in the edible oils segment, they are one of the best places to get your pilot plants project in place. Don’t wait. Hurry before the field fills up!
