                    The 
edible oil refining procedure involves processing a specific quantity of oil through a series of steps including neutralizing, bleaching, dewaxing and deodorization. Crude vegetable oil can contain impurities such as gum phosphatides, free fatty acids, pigments, mono and diglycerides, sterols, tocopherols, hydrocarbons, protein fragments, harmful pesticides or heavy metals. Refining process is required for various edible oil like cottonseeds oil, soybean oil, sunflower oil, palm oil, maize oil, rapeseed oil, palm kernel oil, coconut oil, shea butter, groundnut oil etc. to make these oil free from all impurities, reduce the color, remove wax, odor, separate olein and stearin.
Key Factors Affecting Investment Costs
Before discussing specific figures, it's important to clarify the following:
Production Scale: This is the primary factor determining cost. The investment required for a small edible oil refining plant processing 10 tons of crude oil per day versus a large plant processing 300 tons per day will differ significantly.
Refining Grade: Do you plan to produce first-grade, second-grade, or premium-grade oil? Higher-grade oils require more complex cooking oil refining processes (degumming, deacidification, decolorization, deodorization, etc.), and the equipment investment will also be higher. 
Raw Material Type: The process flow and equipment configuration for refining soybean oil, rapeseed oil, peanut oil, rice bran oil, or palm oil vary, which will affect the final price.
 Degree of Automation: Fully automated PLC-controlled edible oil refining production lines can significantly reduce labor, but the initial investment is higher than semi-automatic or manual lines.
 Plant and Infrastructure: Is there an existing plant? Land, plant construction, and supporting water and electricity facilities are also significant expenses.
 Medium-sized Cooking Oil Refinery (50-100TPD)Suitable for: Companies planning to establish a brand and expand their regional market presence.
Refining Grade: Typically, a full set of edible oil equipment is available for producing first-grade oil (deodorization is crucial).
Equipment Estimate: A highly automated continuous or semi-continuous refinery line is the mainstream choice in the market. Equipment investment typically ranges from several million to over ten million. Huatai Group has extensive experience in such projects and can provide cost-effective, stable cooking oil production lines.
 Large-Scale Cooking Oil Refinery (150-300 TPD)Suitable for: Large grain and oil groups and import and export traders.
Refining Grade: A fully automated, highly efficient first-grade edible oil production line.
Equipment Estimate: The investment is substantial, typically costing tens of millions of RMB. This type of project requires customized design and comprehensive technical support. Henan Huatai Oil Machinery is well-equipped to undertake such large-scale turnkey projects.
