Cocoa Processing Technology

The cocoa processing line follows these stages: bean cleaning removes stones, metal, and foreign material; roasting at 100-140°C for 30-90 minutes; winnowing separates shell from nib targeting 80-82% nib yield; grinding converts nib to cocoa liquor; hydraulic pressing at 400-550 bar produces 40-45% butter yield; and pulverizing converts cake to powder. A DCS controls temperature, pressure, and flow rate at each stage with automated parameter adjustments.

Per-batch traceability records should include: bean origin and supplier, arrival quality test results (moisture, bean count, cut test), roasting profile (temperature curve and duration), winnowing yield percentage, press parameters (pressure, temperature, duration), butter quality analysis (FFA, color, flavor), powder specifications (fineness, pH, fat content), and finished product dispatch records.

Indonesian processors typically blend Sulawesi beans (known for mild flavor) with Ghanaian or Ivory Coast beans (stronger cocoa flavor) to achieve consistent product profiles. The blending management system maintains formulations per product SKU, tracks inventory of each origin bean in silos, calculates optimal blend ratios based on cost and quality targets, and adjusts automatically when origin availability changes.

Key automation opportunities include: automated bean sampling and quality testing at receiving, PLC-controlled roasting with recipe management, automated press cycle control based on real-time yield feedback, robotic palletizing for finished goods, and automated CIP (Clean-in-Place) systems for processing equipment. Industry 4.0 implementations can reduce manual labor by 30-40% while improving yield consistency.

ISO 22000 requires cocoa processors to implement: HACCP plans identifying critical control points (CCPs) at roasting (temperature kill step), metal detection, and allergen cross-contact points; prerequisite programs for sanitation, pest control, and supplier approval; traceability systems with mock recall testing annually; food defense plans; and continuous improvement through internal audits and management reviews.

We usually use a parallel-run approach so the old and new systems operate together during transition, reducing downtime and data risk.

Yes. We design API and import workflows for POS, marketplaces, and bank statements to reduce manual entry and reconciliation errors.

The right choice depends on transaction volume and complexity. We assess your workflow before recommending cloud accounting, POS, ERP, or dashboard tools.
