Continuous bleaching machine

Overview
Oil Bleaching System is an industrial process line designed to remove color bodies, oxidation products and impurities from crude edible oils. The system combines filtration, adsorbent (bleaching clay) contact and controlled heating to improve oil clarity and stability while preparing the product for subsequent refining stages.

Importance of the Oil Bleaching System

• Product quality and consistency: Accurate bleaching ensures uniform color and reduced off-flavors, supporting batch-to-batch consistency for food manufacturers.
• Productivity and continuity: Continuous bleaching lines with automated feeding and dosing enable higher throughput and stable production flow.
• Operational cost control: Efficient raw material handling and closed-loop processes limit material loss and reduce energy and waste management costs.
• Hygiene and safety: Closed systems minimize contamination and spillage, improving plant hygiene and meeting food safety requirements.

Products and Services (related to the bleaching system)

• Raw material storage and silos: Custom silos and feeders sized for bleaching clay and other additives to ensure dry, protected storage and controlled discharge.
• Pneumatic conveying systems: Vacuum and dense-phase options for dust-free transfer of bleaching clay and powders in closed pipelines to preserve product integrity.
• Dosing and feeding systems: High-precision gravimetric and volumetric feeders for exact dosing of bleaching clay, chemicals and oil recirculation streams.
• Process automation systems: Integrated PLC/SCADA control for batch sequencing, continuous flow control, data logging and alarm management to ensure repeatable process parameters.

Sectoral Applications

• Vegetable oil refiners: Primary application for removal of pigments and contaminants prior to neutralization and deodorization.
• Food processing manufacturers: Bakeries, confectionery and prepared-food plants requiring stable oil quality for product formulation.
• Beverage and ingredient producers: Use in flavor, emulsion and ingredient preparation where oil clarity and stability affect final product quality.
• Bulk edible oil packers: Systems suitable for large-scale packing and distribution with consistent dosing and minimal downtime.
