Advanced centrifugal impact technology for cocoa bean separation
Revolutionizing cocoa processing with a novel centrifugal impact method that enhances nib purity and yield while minimizing energy use and shell contamination. This innovative approach significantly improves separation efficiency over traditional methods.
Overview
Lambton College introduces a groundbreaking approach to cocoa bean processing using advanced centrifugal impact technology. This innovative method revolutionizes traditional cocoa processing by employing a controlled centrifugal shattering unit. Unlike conventional cracking and winnowing, this technology precisely fractures cocoa beans along natural fracture lines, reducing nib damage and optimizing shell separation. The result is a significant enhancement in nib purity and yield, offering a more sustainable and economically beneficial solution for the cocoa industry.
Technical specifications
Key features:
- Controlled Centrifugal Shattering: Utilizes precise mechanical separation to achieve cleaner breaks of cocoa beans, minimizing shell contamination.
- Multi-Stage Air Classification: Integrates advanced air classification stages to further refine the separation process, enhancing nib purity.
- Density Sorting Equipment: Employs density sorting to ensure high-quality nib extraction and reduced nib loss.
- Parameter Optimization: Systematic testing of impact speed and chamber design to tailor the process for various cocoa bean types.
This technology aims to achieve less than 0.5% w/w shell contamination in nibs, increased nib yield, and reduced energy consumption compared to traditional methods.
Technology readiness level
Currently, this technology is at TRL 3, with successful bench-scale prototyping and parameter optimization underway. Future plans include pilot-scale validation and the integration of advanced separation units, focusing on scalability and economic viability for continuous 24/7 operation.
