The tank group extraction equipment for oil processing is Main equipment for medium and small-scale oil production, consisting of extraction tanks, solvent recovery systems, meal desolventizing systems, and miscella treatment systems. Adopting batch-type tank group operation, it is suitable for alternating processing of multiple oil seeds (soybeans, rapeseeds, etc.), featuring a simple structure and flexible operation.
2. Working Principle
Based on the solvent extraction principle (like dissolves like): 6# solvent oil is used to dissolve oil in oilseeds to form miscella. Oil and solvent are separated via distillation/steam stripping (utilizing boiling point differences), the solvent is recovered and recycled, and the meal is desolventized and dried to become a finished product.
3. Main Procedures
Feeding: Pretreated oilseeds are loaded into leaching tanks and sealed;
Leaching: Solvent is sprayed/soaked with oilseeds in countercurrent to dissolve oil and form miscella;
Separation: Miscella is separated into crude oil through evaporation and steam stripping, and the solvent is condensed for recovery;
Desolventizing: Wet meal is desolventized, then dried and cooled to obtain finished meal;
Treatment: Tail gas and wastewater are treated up to standard to avoid solvent leakage.
4. Main Advantages
High oil extraction efficiency, with residual oil rate in oilseeds ≤ 1%;
Adaptable to multiple oilseeds with flexibly adjustable parameters;
Solvent recovery rate ≥ 95%, reducing production costs;
Low equipment investment and operation/maintenance costs, suitable for medium and small production capacities;
Minimal protein denaturation in meal, ensuring high quality;
Single tank failure does not affect overall operation, enabling flexible operation.
Features: Abundant supply, cost-effective, high fat content
2. Equipment Specifications
The system is designed with fully automated operations including feeding, slag discharge, and oil-residue separation, ensuring simple operation and compliance with environmental standards.
When animal adipose tissue is heated and melted, oil is released from it. Under the effect of heat, the oil in animal fat cells transitions from a solid to a liquid state. Heating animal fat reduces the viscosity of the oil and lowers its surface tension. This is the result of thermal molecular motion and the weakening of intermolecular cohesion. The reduction in cohesion makes it easier for the oil to separate from the cells and allows the oil droplets from individual cells to coalesce into larger masses. Simultaneously, due to differences in specific gravity, the oil separates from the protein.
3. Rendering Process
Melting is conducted under vacuum, which removes moisture from the raw materials, yielding dry oil and dry oil residue.
As the equipment is sealed, the entire melting process avoids any adverse effects of air oxidation on the oil, such as an increase in peroxide value and darkening of color.
It ensures the production of high-quality oil, as organic substances that enhance the edible value and storage stability of the oil (such as vitamins, stearyl alcohol, lecithin, etc.) are preserved.
The oil undergoes partial deodorization while also eliminating unpleasant off-flavors.
High-quality oil residue is obtained, as the proteins remain largely undenatured due to the vacuum melting process.
Thermal energy loss during the melting process is reduced.

The primary raw materials for lard rendering are porcine-derived fats, mainly including fresh pork leaf lard, back fat, belly fat, and mesenteric fat. Raw materials are selected from the fresh fat tissue of healthy pigs, adhering to screening criteria of no odor, no spoilage, and no impurities to avoid affecting the flavor and quality of the finished oil. These raw materials are widely available, can be purchased in bulk from pig slaughterhouses and meat processing plants, with controllable costs and stable supply, laying the foundation for ensuring lard yield and natural flavor.
II. Equipment Overview
Mainstream lard rendering equipment is made of food-grade stainless steel, complying with food hygiene and safety standards, and is classified into three categories: small-scale rendering pots for home workshops (capacity 5-50L, manual operation, simple structure, suitable for small-batch production), high-temperature atmospheric rendering machines for small and medium-sized processing plants (capacity 100-500L, equipped with temperature control systems and stirring devices, moderate automation), and continuous vacuum low-temperature rendering production lines for large-scale production (integrated equipment including cleaning, cutting, rendering, separation, and filtration, with precise temperature control, suitable for mass production). All equipment features high temperature resistance, corrosion resistance, and easy disassembly for cleaning; some high-end models are also equipped with oil purity detection modules to further ensure product quality.
III. Rendering Process
Raw Material Pretreatment: Fresh fat raw materials are rinsed with clean water to remove blood, hair, and other impurities, then cut into 2-5cm pieces by a meat cutter (to increase heat transfer area and shorten rendering time);
Feeding & Rendering: Cut raw materials are put into the equipment. High-temperature atmospheric models operate at 120-150℃ for 2-4 hours, with uniform heating via stirring devices to prevent local burning; vacuum low-temperature models work at 80-100℃ under negative pressure for 3-5 hours to reduce oil oxidation;
Oil-Residue Separation: After rendering, liquid oil and oil residue are quickly separated through the equipment’s built-in filter screen or centrifugal separation device. The oil residue can be recycled as feed raw material;
Refining & Purification: The separated crude oil undergoes multi-layer filtration (quartz sand filtration + activated carbon adsorption) to remove fine impurities and odorous substances;
Cooling & Finished Product: The refined oil is introduced into a cooling tank, cooled naturally to room temperature or refrigerated for 12-24 hours for precipitation, removing residual impurities to finally obtain clear and pure finished lard.
IV. Core Advantages
High Efficiency & Yield: Compared with traditional iron pot rendering, the oil yield is increased by 15%-20%. Small-scale equipment can produce 50-200kg of finished products per batch, while large-scale production lines can reach several tons per day, meeting the needs of different production scales;
Quality Assurance: Food-grade stainless steel material prevents oil contamination; the precise temperature control system avoids excessive oil oxidation, maximizing the retention of lard’s natural flavor and nutrients. The finished oil is clear, free of impurities, and has a long shelf life;
Easy Operation: Equipped with digital control panels, the equipment allows precise setting of temperature and time, with high automation. No professional technicians are required for operation, and it is easy to disassemble and clean, reducing operation and maintenance costs;
Energy Conservation & Environmental Protection: Some vacuum models adopt waste heat recovery systems, reducing energy consumption by more than 25% compared with traditional equipment, in line with green production concepts. Meanwhile, oil residue is recycled to achieve maximum resource utilization;
Wide Adaptability: From small-scale equipment for home workshops to continuous production lines for large food processing plants, it can be flexibly selected according to production capacity requirements, with low investment threshold and short payback period.
High-quality fish oil typically comes from fresh, sustainable, small oily fish like anchovies.
Fish oil is primarily sourced from oily, cold-water fish:
Key species: Anchovy (most common, balanced EPA/DHA), sardine/mackerel (rich in Omega-3s), herring (traditional Northern European source), plus tuna/salmon by-products (tuna oil high in DHA, salmon oil may have astaxanthin).
Raw material types: Whole small oily fish (best for high-grade supplements, consistent quality) or fish processing by-products (sustainable/cost-effective, needs strict purification).
Special case: Cod liver oil (from lean cod, high in natural Vitamins A and D).
Key factors: Freshness (prevents oxidation), sustainability (small fish have less heavy metals), purity (molecular distillation removes contaminants).
