The Comprehensive Process Flow of a Food Oil Refined Unit

The journey from crude oil to refined edible oil involves a series of meticulously controlled stages, each designed to remove specific impurities while preserving the oil's nutritional value and sensory qualities. Leading food oil refined unit manufacturers employ state-of-the-art technology across these stages:

1. Pre-treatment (Oil Seed Preparation & Extraction)

Before refining, raw oilseeds undergo preparation. This often involves cleaning, dehulling, and flaking. For instance, the Oil Processing Equipment - Flaking Machine is a crucial initial step, creating thin flakes from oilseeds to maximize oil extraction efficiency during pressing or solvent extraction. This mechanical preparation significantly impacts downstream refining costs and quality.

Schematic Steps for Oil Refining:

1. Degumming: Crude oil contains phospholipids (gums) that are hydrated and then separated, typically by centrifugation. This step removes substances that can cause cloudiness and reduce shelf life.
2. Neutralization (De-acidification): Free fatty acids (FFAs) are reacted with an alkali solution (e.g., caustic soda) to form soaps, which are then separated. This significantly improves taste and stability.
3. Bleaching: The oil is treated with activated bleaching earth or activated carbon under vacuum to remove pigments, residual soaps, and other impurities, improving color and reducing oxidative susceptibility.
4. Deodorization: This high-temperature, vacuum steam distillation process removes volatile compounds responsible for undesirable odors and flavors, as well as residual FFAs and pesticides. This is often the final stage for many refined oils.
5. Dewaxing/Fractionation (Optional): For certain oils like sunflower or palm oil, this step removes waxes that can cause turbidity at lower temperatures, or separates oil into fractions with different melting points.

Materials, Manufacturing, and Testing Standards

The construction of a food oil refined unit demands materials that can withstand high temperatures, corrosive chemicals, and continuous operation. Key materials include food-grade stainless steel (e.g., SS304, SS316) for contact parts, ensuring product purity and corrosion resistance. Manufacturing processes involve precision casting, forging, and advanced CNC machining to achieve tight tolerances and robust components. Each stage of manufacturing adheres to stringent quality control protocols.

Testing standards like ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and specific industry standards such as ANSI (American National Standards Institute) are strictly followed. Pressure vessels and critical components are often built to ASME Boiler and Pressure Vessel Code standards. These rigorous standards ensure a service life often exceeding 20-30 years with proper maintenance, making these units a long-term investment.

Target industries for these sophisticated refining units include the petrochemical sector (for processing byproducts), metallurgy (for specialized lubricants), and most predominantly, the entire food and beverage industry for producing edible oils, fats, and derivatives. In typical application scenarios, modern refining units demonstrate significant advantages such as 20-30% energy saving through efficient heat recovery systems and superior corrosion resistance due to specialized material selection and surface treatments, minimizing downtime and extending operational lifecycles.

Technical Specifications: Focusing on the Flaking Machine

A critical piece of equipment in the pre-treatment stage for many oils, especially those from seeds, is the flaking machine. Its efficiency directly influences the oil extraction yield and the quality of the crude oil entering the refining process. Understanding its technical specifications is key to optimizing the entire production line.
