How Does a 3-Tank Refinery Improve on the 2-Tank System?

A 3-tank oil refinery machine improves quality by separating the degumming and deacidification processes into two dedicated tanks. This is the key difference and the main reason for the upgrade. It gives you much better control over the refining process.

In a simpler 2-tank oil refinery machine, these two critical steps are combined in the first tank. This is efficient for basic refining. But by giving each process its own dedicated tank, the 3-tank oil refinery machine allows for a more thorough and precise job. You can optimize the conditions for removing gums, and then separately optimize the conditions for removing acids. This separation results in a more complete removal of impurities. The final oil is cleaner, more stable, and has a better taste. It is this higher level of purity that allows you to market your product as a higher-grade oil and command a better price.

How does a refining machine refine oil?

The process in a Refining Equipment is a logical, three-stage batch operation. Each tank performs a specific, crucial function. We design these systems to be easy for you to manage, giving you consistent results with every batch.

You will process your crude oil through three stages to achieve a high level of purity. The flow is simple: oil moves from Tank 1 to Tank 2, and then to Tank 3, with a filtering step at the end. This methodical approach ensures that each type of impurity is removed effectively before moving to the next stage. It is a systematic way to create a high-quality product that you can be proud to sell. Let’s look at what you will do at each step.

Step 1: The Degumming Tank (Tank 1)

Your process begins here. You will pump the crude oil into the first tank. This tank is specifically for degumming. You will heat the oil and mix it with hot water or a hydrating agent. This causes the sticky gums (phospholipids) to clump together. Because this tank is dedicated only to this task, you can perfectly control the temperature and mixing time to get the best possible separation. After settling, you drain off the gums, leaving a cleaner oil ready for the next step.

Step 2: The Deacidification Tank (Tank 2)

The degummed oil is then moved to the second tank. This tank is dedicated to removing the Free Fatty Acids (FFAs). You will add a precise amount of an alkali solution. Having a separate tank means there are no leftover gums to interfere with the reaction. The alkali neutralizes the acids, turning them into soapstock. This soapstock settles at the bottom and is drained away. This step is critical for improving the oil’s taste and making it stable for cooking. The result is a much purer oil than what a combined process can achieve.

Step 3: The Decolorization Tank (Tank 3)

The final tank is for decolorization, or bleaching. The oil from Tank 2 is pumped here. In this tank, the oil is heated under a vacuum and mixed with activated clay. The clay absorbs the unwanted color pigments. Because the oil is already very clean from the first two steps, the clay works more efficiently. After mixing, the oil and clay mixture is sent to a leaf filter or filter press. The filter removes the clay, and the oil that comes out is clear, light in color, and has a premium appearance.

Specifications Reference for Small Refining Machines

• Daily processing capacity ranges widely, from 200 kg/day for small oil mills to 5 tons/day for medium-scale production, all customizable.
• For example, if you select a processing capacity of 500kg per batch (with each tank holding approximately 167kg and three tanks operating in a continuous cycle), this setup is suitable for small oil mills producing 1-2 tons per day.
• Power Configuration: Typically equipped with power units ranging from 15 to 37 kW, operating at 380 V, meeting industrial power requirements.
• Some equipment utilizes variable frequency technology, enabling adjustment of stirring and heating speeds based on oil characteristics to reduce energy consumption.
• Tank Structure: The tank is constructed from 304 stainless steel, offering corrosion resistance and ease of cleaning, and meeting food-grade standards.
• Three independently designed tanks perform dephosphorization, decolorization, and deodorization functions respectively, with material circulation achieved through piping and oil pumps.

Who is the 3-Tank Oil Refinery Machine Perfect For?

The 3-tank oil refinery machine is the perfect choice for a business that is serious about quality but still needs a cost-effective solution. It is for the entrepreneur who is ready to move up in the market.
