Alkalizing system for cocoa powder coloring
Achieve precise cocoa powder coloration and enhanced flavor development with a system that integrates seamlessly into your mixing and roasting process, optimizing pressure, temperature, and time for consistent, high-quality results in confectionery and snack production.

Adjusts pH and Colors Cocoa Products
The CNA Alkalizing System from Bühler Group is a cutting-edge solution for precise pH adjustment and color enhancement in cocoa processing. Designed specifically for food processors, cocoa manufacturers, and confectionery producers, it utilizes ribbon mixing technology and an agitating spiral to ensure gentle yet efficient mixing, reducing cycle times and increasing throughput. This system is integral for applications such as debacterization, flavor development, and cocoa powder coloring, capable of delivering a full spectrum of hues through controlled pressure-temperature-time profiling.
Operating seamlessly within both batch and continuous production lines, the CNA supports diverse industries, including dairy and baking, by processing end-products like chocolate bars and bakery fillings. Its robust mechanical design ensures reliable performance with minimal maintenance, boasting easy-to-adjust mechanical seals accessible from the outside. The system’s energy-efficient operation is further enhanced by optional solutions injection, such as invert sugar, to intensify flavors during roasting. Additionally, Bühler offers full recipe management and customization support to align with specific market needs, while ensuring compliance with food safety standards.
