For nut grinding of almonds and cashews into paste, should we choose a colloid mill or a nuts grinder built for whole kernels?

A colloid mill acts effectively as a nuts grinder once nuts have been roughly crushed, turning almonds, cashews or similar kernels into smooth nut butter or paste through repeated shear passes, while releasing natural oils that aid emulsification. For whole, unbroken nuts a coarse pre-grinder is usually needed first, after which the colloid mill handles the fine nut grinding stage to achieve the desired creamy consistency.

When selecting equipment for almond or cashew paste production, it is important to consider not only the type of grinding unit but also the entire processing sequence. From an engineering perspective, whole kernels usually require preliminary size reduction to avoid excessive mechanical load on the fine grinding equipment. After this stage, a GlobeCore colloid mill can be used for final dispersion, where the adjustable rotor-stator gap allows control of the paste consistency and particle size.
During processing, the high shear forces generated inside the mill help release natural oils from nuts and improve the uniformity of the final product without the need for additional emulsification equipment. The CLM-100.3 laboratory colloid mill can be used for developing formulations and testing different nut varieties, while industrial GlobeCore colloid mills can be selected according to required capacity.
