Product Overview

400mm Automatic Chocolate Production Line (Industrial Grade) – Core Equipment for Standardized Production from Cocoa Beans to Finished Products

Configured to 400-type standards, it is suitable for producing dark chocolate, milk chocolate, white chocolate and compound chocolate, supporting multi-form finished product output such as bars, blocks, and coated products (wafers, biscuits, nuts), with a stable capacity of 80-120kg/h, making it the core choice for professional chocolate factories and food deep-processing enterprises to build standardized production lines.

Real Core Production Process (Industrial Standard)

1. Cocoa Bean Pretreatment: Cleaning (removing impurities) → Roasting (120-140℃, 30-60 minutes) → Crushing & Dehulling (separating cocoa nibs from shells) → Grinding (producing cocoa liquor/cocoa powder);

2. Mixing & Grinding: Mixing cocoa liquor/powder, sugar, milk powder (for milk chocolate), cocoa butter and other raw materials according to formula, refining particles to 20-30μm via three-roll mill (ensuring fine texture);

3. Conching: 500L chocolate conche continuously mixes, shears and oxidizes for 8-24 hours, enhancing chocolate flavor and texture;

4. Tempering: Precisely controlling chocolate temperature via tempering machine (heating to 45-50℃ → cooling to 27-28℃ → reheating to 31-32℃), promoting stable crystallization and ensuring finished product luster and taste;

5. Molding/Coating: 400mm wide molding molds/coating belt, realizing block/bar molding or uniform coating on food surfaces;

6. Cooling & Solidification: 10m tunnel cooler with gradient cooling (20℃→10℃→5℃) to avoid unstable crystallization, solidification time 15-25 minutes;

7. Post-Processing: Demolding → sorting → pre-packaging finishing (deburring, foreign matter screening) to complete finished product output.
