I. Working PrincipleThe Vertical Leacher is equipment used in the oil processing industry to extract oil from oilseeds. It utilizes a vertical leaching vessel where oilseeds contact solvents (e.g., hexane). The solvent dissolves the oil, forming miscella. The miscella undergoes evaporation and stripping to separate the solvent, yielding pure oil. Its vertical design enablesperiodic batch processing in single vessels, facilitating production coordination and suiting intermittent operations.II. Technical FeaturesVertical Structure: Space-efficient design enhances productivity.High-Pressure Operation: Improves leaching efficiency in specific applications.Mechanical Agitation-Free: First-generation models eliminate complex stirring mechanisms, reducing maintenance.Multi-Stage Series Operation: Enhances extraction efficiency through cascading vessels.Efficient Solvent Recovery: Integrated systems separate and recycle solvents from miscella.III. ApplicationsOil Processing: Extracts oil from palm kernel meal, soybeans, rapeseed, peanuts, etc.Metallurgy: Used in high-pressure acid leaching (HPAL) of laterite nickel ore to extract nickel and cobalt.Sugar Industry: Extracts sucrose from sugar beet cells.IV. Equipment SelectionCapacity: Match processing capability to production scale.Solvent Consumption: Prioritize low-solvent models to reduce costs.Steam Consumption: Select energy-efficient designs.Material: Opt for corrosion-resistant materials (e.g., titanium-clad steel) for longevity.V. AdvantagesHigh Efficiency: Vertical design and pressure operation optimize extraction.Energy Savings: Efficient solvent recovery and low steam consumption lower operating costs.Operational Stability: Agitation-free design minimizes complexity and maintenance.Safety & Reliability: Stable operation reduces safety risks.Vertical Leachers are efficient, energy-saving, and safe, making them essential in oil processing and ore leaching industries.

I. Working PrincipleMaterial Handling & Spraying: Prepared flakes or expanded meal enters drag chain frames, forming a material bed. Solvent is sprayed, establishing a liquid level on the bed.Leaching & Draining: Chains driven by a transmission slowly push material through isolated frames. This minimizes miscella mixing between stages, maintaining a steep concentration gradient for enhanced mass transfer. Material is dragged over upper/lower grid plates, improving utilization. A mid-process flip enhances leaching uniformity.Miscella Circulation: Repeated solvent/miscella spraying dissolves oil, forming miscella. Filtered miscella flows to collection hoppers. Concentrated miscella is pumped to holding tanks for evaporation/stripping; dilute miscella recirculates.Wet Meal Handling: After ~60 mins leaching, spent meal is pushed to the discharge by scrapers and conveyed to the desolventizer.II. Technical FeaturesExcellent Sealing: Fully enclosed design minimizes solvent loss.Frequency-Controlled Speed: Adjustable chain speed via frequency converter optimizes solvent penetration for different materials.Independent Leaching Cells (Drag Frames): Prevents miscella cross-flow between stages, maintaining concentration gradients.Full Counter-Current Flow: Maximizes miscella concentration and leaching efficiency.Auto-Speed Adjustment: Reduces failure rates and ensures stable operation.III. Key ComponentsMain drive unitTensioning deviceDriven unitFeed hopperDrag chain with scrapersGrid plate/screen frameFeed rate controllerSpraying systemSight glass flushing deviceEnclosed casingDrive systemUpper/lower miscella hoppersIV. AdvantagesHigh Efficiency: Low bed height improves solvent penetration; material flipping loosens/realigns the bed.Energy Savings: Optimized spraying/draining reduces solvent & energy use.Stable Operation: Robust design ensures low failure rates.Safety & Reliability: Sealed enclosure minimizes leakage risks.This efficient, energy-saving, and reliable leacher is a mainstream choice in oil processing.
