What Is Animal Fat Oil Refining Equipment?
The animal fat oil refining system integrates the functions of alkali refining, degumming, deacidification, decolorization and deodorization of crude oil. Through a series of physical and chemical processes, phospholipids, gums, free fatty acids, pigments, and odor compounds are removed from animal fats, resulting in a purer, more stable finished oil.
Unlike manual or semi-open units, GQ-Agri’s turnkey automated vacuum refining line integrates degumming, deacidification, bleaching, filtration and deodorization processes into one complete, continuously operating facility. This reduces manual labor, improves production consistency and reduces energy consumption. Each animal fat oil refining line is custom-built and assembled based on the customer’s crude oil condition, target grade (food grade or industrial grade), production capacity, and local regulatory requirements.
Key Stages in the Animal Fat Refining Process.
After animal fat rendering, a series of refining processes are carried out according to the target sales objectives of the finished oil. Refining is an essential step, especially when preparing the crude oil for food processing or pharmaceuticals. The animal fat refining process is as follows:
Crude oil → Degumming and dephosphorization → Deacidification → Decolorization → Filtration → Vacuum deodorization → Finished oil.
The entire refining process for animal oils is controlled and designed to remove impurities and improve the quality, transparency, flavor neutrality, and shelf stability of the oils. It improves the smoke point while enhancing food safety.
- Degumming (Wet or Dry Process).
The crude oil is hydrated (wet) or conditioned (dry) to remove phospholipids and gums. The choice between wet and dry processes depends on the phospholipid content and local water/wastewater treatment conditions. - Deacidification (Alkaline Deacidification).
Alkalis (such as sodium hydroxide) are used to neutralize free fatty acids and organic acids in the oil to stabilize the base oil and prevent rancidity. - Bleaching (Vacuum Adsorption).
Under vacuum conditions, oils are mixed with activated clay to adsorb pigments and trace impurities, thereby controlling color and further purifying the oil. The reaction is typically carried out at 95-110°C for 15-25 minutes; high temperature and vacuum conditions enhance the decolorization effect. - Filtration (Spent Clay & Fines Removal)
Pass the bleached oil through a vibration blade filter to remove spent clay and fine particles, improving brightness and transparency. - Deodorization (High-Temperature Vacuum Distillation)
Utilizing the significant difference in volatility between odor-causing substances and triglycerides in the oil, odor-causing substances (such as free fatty acids, aldehydes, and ketones), volatile components, and residual moisture are removed by steam distillation under high temperature and high vacuum conditions, yielding refined oil that meets edible standards. - Finished Oil.
The deodorized oil can optionally receive polishing filtration for extra visual brightness, then goes to storage or packaging.
What Are the Main Machines Included in Animal Fat Oil Fat Refining Equipment?
A series of tanks and auxiliary units with different functions together constitute a complete animal fat refining system. They work together to refine and filter the previously rendered animal crude oil into edible finished oil.
- Refining Pots: Made of stainless steel, these pots feature automatic temperature and pressure control, high efficiency, energy saving, safety, and hygiene. Two refining pots are used for degumming and deacidification processes, respectively. Depending on the function, a stirrer or alkali tank may be provided.
- Decolorization System: Includes decolorization tanks, bleaching clay tanks, and filtration devices. The sealed vessel is used for adsorption and decolorization under vacuum conditions. Activated clay is used to decolorize the oil and adsorb residual pigments and impurities. The decolorized oil then enters the filtration stage for clarification.
- Vibration Blade Filter: Filters out residual waste bleaching clay and fine particles from the semi-finished oil after bleaching. This makes the oil clearer and brighter, facilitating subsequent deodorization treatment.
- Vacuum Deodorization Kettle: Operates under high temperature and negative pressure, distilling to remove deep-seated odors, volatile substances, and moisture, yielding a pure-tasting neutral refined oil. The deodorized oil proceeds to storage or optional polishing. The deodorized oil proceeds to storage or optional polishing.
- Polishing Filter (Optional): Provides final micro-filtration after deodorization, enhancing brightness and transparency before the oil is stored or packaged.
Auxiliary units and equipment:
- Vacuum Unit: Maintains a steady negative pressure for both bleaching and deodorizing stages, improving impurity removal and protecting oil quality.
- Steam Generator: Produces controlled steam for heating and deodorization, ensuring stable temperature and efficiency throughout the process.
- Gas-liquid Separator: Separate condensate from vacuum gases to keep the system clean and maintain stable pressure in continuous operation.
- Air Compressor: Provides compressed air to dry the clay in the vibratory filter and power the vibratory filter.
- Electrical Control Cabinet: The central hub that monitors temperature, vacuum, and flow parameters across all stages, enabling fully automated and safe control.
- Auxiliary Tanks: Water tanks and oil tanks provide intermediate storage and cooling circulation, ensuring stable and balanced material flow between different stages. There are also auxiliary boxes such as a white clay box for “storing activated white clay”, a soapberry pot for “hydrating and salting out soapberry”, and a hot water box.
- Power Pumps: Drive circulation and transfer through every stage, including decoloring, deodorizing, gear, vacuum pump, water and soap pumps, guaranteeing reliable throughput and utility flow.
Câu hỏi thường gặp
What oil quality can be achieved after refining?
Ideally, fully refined oils should have an acid value below 0.15 mg/g, a peroxide value below 10 mmol/kg, and extremely low moisture and impurity content (depending on equipment configuration and crude oil variety and quality). Refining depth can be customized to your needs and budget; depending on the configuration, refined oils can meet food-grade or industrial-grade standards.
How do vacuum stages improve results?
Vacuum reduces the oil’s contact with oxygen, preventing oxidation and nutrient loss. Especially in the deodorization stage, volatile substances and odors can be effectively removed under controlled temperatures, thus maintaining the oil’s stability and color.
Can the line be tailored to my crude and capacity?
Yes. GQ-Agri engineers customize kettle sizing, vacuum/steam duty, filtration area and controls to match crude quality, throughput, and target grade. Installation and commissioning guidance, as well as after-sales technical services, are provided to ensure the entire system meets your oil quality goals while optimizing energy utilization and environmental performance.
