Annular Leachers are efficient solid-liquid extraction equipment widely used for vegetable oilseed leaching.
Material Handling & Spraying: Material is fed by scraper conveyor and sprayed counter-currently with miscella from concentrated to dilute.
Leaching & Draining: Fresh solvent is sprayed last. Drained wet meal is discharged to desolventizer; miscella goes to evaporation.
Solvent Recovery: Filtered miscella is pumped to a holding tank; dilute miscella recirculates.
Annular Design: Material turnover ensures thorough leaching and low residual oil.
Shallow Material Bed & V-Shaped Grids: Dead-zone-free movement and self-cleaning grids ensure efficient drainage, reducing solvent in wet meal.
Unique Sealing: Prevents solvent leakage from main shaft, enhancing safety.
Uniform Feeding/Discharge: Ensures stable system pressure.
Suitable for leaching rice bran (high powder content), soybeans, rapeseed, etc.
Capacity: 50-5000 TPD
Solvent Consumption: ≤0.6 kg/ton material, Recovery >99.5%
Steam Consumption: ≤280 kg/ton material (0.8MPa)
High leaching efficiency, especially for powdered materials (e.g., rice bran, palm meal)
Energy-saving (low solvent/steam consumption)
Stable operation with low maintenance
Safe and reliable (no solvent leakage)
Annular Leachers are efficient, energy-saving, and safe, making them mainstream in oil processing.
