Cocoa Nib & Nut Paste Grinder Machine
AkayGAM cocoa nib and nut paste grinders are industrial impact grinding machines designed to convert roasted cocoa nibs and nuts into dense, pumpable paste. The system uses a two-stage configuration with a top crushing unit and a high-speed pin grinding chamber to provide controlled particle size reduction and consistent paste formation.
Unlike refiners designed for ultra-fine particle size, this grinder performs the primary paste formation step, producing cocoa liquor or nut paste for direct use or for finishing in downstream refining systems.
Typical products include:
The resulting paste can be used directly where pre-refined texture is acceptable or routed to downstream finishing equipment.

We manufacture cocoa nib and nut paste grinders for artisan chocolate producers, pilot plants, and medium-scale confectionery operations, supporting repeatable pre-grinding of roasted ingredients for cocoa liquor and nut paste production.
Typical applications include:
The grinder operates as a continuous impact mill, delivering stable throughput and repeatable paste consistency.

Description for the cocoa nib and nut paste grinding process
The grinding process begins in the upper crushing zone, where roasted cocoa nibs or nuts are reduced to smaller fragments. This pre-crushing stage stabilizes material flow and prepares the product for efficient pin grinding.
The product then enters the lower pin grinding chamber, where high-speed rotating pins generate controlled impact and shear forces. These forces further reduce particle size while releasing natural cocoa butter or nut oil, transforming the material from a granular solid into a continuous viscous paste.
This process produces pre-refined paste with typical particle size down to approximately 500 microns, depending on product characteristics and operating parameters.
This particle size range is suitable for:
Role in chocolate and nut paste production lines
The cocoa nib grinder provides the primary paste formation stage within chocolate and nut processing lines, enabling efficient downstream refining, storage, or direct use depending on product requirements.
The grinder operates as a continuous impact mill and can be used either as a standalone paste production unit or as a pre-grinding stage feeding fine refiners, storage tanks, or transfer pumps. This flexibility supports both small-scale production and integration into industrial chocolate processing systems.
Particle size and further refining
The pre-ground paste can be processed in a ball mill refiner when finer particle size distribution or smoother texture is required, achieving typical chocolate fineness levels between 18 and 25 microns.
This staged grinding and refining approach improves refining efficiency, stabilizes downstream processing, and reduces total refining time.

These ball mill refiners are used after pre-grinding to achieve the fine particle size required for chocolate, praline, and nut spread production.
