Cocoa Husk Powder Processing with Air Classifier Mill (ACM)–Yinda Ultrafine Grinding Machinery
Introduction: What is Cocoa Husk?
Cocoa husk, also known as cocoa bean shell, is the thin, brittle outer layer of cocoa beans, separated during roasting and cracking in chocolate production. Once treated as waste, it is now valued for its rich dietary fiber, polyphenols, and pleasant cocoa aroma. Today, cocoa husk is used in food, beverages, feed, agriculture, and eco-friendly materials.
Why Cocoa Husk Needs Ultra-fine Grinding
In its natural form, cocoa husk appears as irregular flakes with low bulk density, making it unsuitable for direct industrial use. Without proper grinding, it presents several challenges:
- Inconsistent particle size → Difficult to blend uniformly in food and beverages.
- Rough texture → Large flakes affect mouthfeel and limit direct consumption.
- Poor extractability → Valuable compounds like polyphenols are not efficiently released.
- Bulky storage & transport → Low density increases handling costs.
Grinding cocoa husk into fine, uniform powder solves these problems, improving functionality, processing efficiency, and overall commercial value.
Yinda YDWF Series Air Classifier Mill(ACM) for Cocoa Husk Grinding
Yinda Air Classifier Mill Ultrafine Grinding Mill is designed for efficient size reduction of lightweight, fibrous materials such as cocoa husk. Unlike conventional pulverizers, the ACM integrates impact grinding and air classification in a single system, ensuring precise and continuous production of uniform fine powders.

Structure of Yinda Air Classifier Mill(ACM) Ultrafine Mill
- Milling Part
The core grinding chamber where cocoa husk flakes are reduced through high-speed impact and shear forces, achieving consistent particle size. - Connecting Pipes
Seamlessly link each section of the system, allowing smooth airflow and material transfer without blockages. - Cyclone Separator & Discharge Part
Efficiently separates fine powder from the circulating air and discharges the qualified product. This design improves powder yield and ensures stable output. - Dust-free System
Minimizes airborne particles, creating a clean and hygienic production environment. It not only reduces material loss but also helps manufacturers meet food safety and environmental standards. - High-pressure Blower
Provides the strong airflow needed to transport particles and support the air-classification process, ensuring efficient separation of fine and coarse powder.
Built entirely from food-grade SS 304/316L with internal and external polishing treatment, the ACM mill guarantees hygiene, durability, and easy cleaning. It can achieve 80–400 mesh ultra-fine cocoa husk powder with a qualified recovery rate of 99–99.5%.
Cooling System for Heat-sensitive Cocoa Husk-Industrial Air Cooling Chiller
Cocoa husk is a heat-sensitive material, with valuable aroma and polyphenols that can degrade at high temperatures. To preserve these properties, the Yinda Air Classifier Mill can be equipped with an industrial air-cooling chiller. The chiller maintains a stable, low temperature during high-speed grinding, preventing aroma loss, preserving polyphenols, and ensuring high-quality cocoa husk powder. This cooling system also prevents particle adhesion and clogging, allowing continuous, efficient production.
Processing Workflow of Cocoa Husk Powder on Yinda Air Classifier Mill with Air Cooling Chiller
The cocoa husk flakes are first fed into the milling chamber of the Yinda ACM, where they are pulverized by high-speed impact and shear forces. The integrated air-cooling chiller maintains a low temperature throughout the grinding process, protecting heat-sensitive compounds such as aroma and polyphenols without affecting grinding efficiency. The strong airflow generated by the high-pressure blower carries the particles through the connecting pipes to the cyclone separator. Combined with cooling, the airflow prevents particle adhesion and local overheating. Fine cocoa husk powder is collected as the final product, while coarse particles are returned to the milling chamber for re-grinding. This closed-loop circulation ensures uniform particle size, maximizes powder yield, and maintains consistent quality for downstream applications such as chocolate, bakery, beverages, and dietary supplements.
