Cocoa Nibs Grinding Machine

I. What Is the Machine for Cocoa Nibs Grinding

Grinding cocoa nibs into a smooth paste requires specialized cocoa nib grinding machines. Our SL series stone type cocoa grinder can reach such grinding performance. It can efficiently transform cocoa beans into a silky, rich-flavored cocoa liquor.

II. Key Features of Cocoa Nib Grinder

Durable and Sharp Grinding Stones: Most cocoa nib stone grinder machines use natural granite as the grinding parts. Granite is hard and wear-resistant, maintaining stable grinding performance even after long-term use. Certainly, it will also be less prone to contamination due to wear.

Controllable Fineness and Excellent Taste: By adjusting the gap between the stone wheels, the rotation speed, and the grinding time, stone mills can grind cocoa paste to a fineness of less than 20 micrometers (μm). This fineness results in a cocoa paste that melts in your mouth with a silky smooth texture.

Multi-functional Applications: In addition to grinding cocoa beans, these stone mills are also commonly used to make various nut pastes such as sesame paste, peanut butter, almond butter, and cashew butter.

III. Working Principle of Cocoa Nib Grinder

The core principle of grinding cocoa in a stone mill is the strong relative motion generated between the stone wheel and the bottom pot (usually made of hard materials such as stone or stainless steel).

Relative Motion and Shear Force: The upper stone wheel and the lower pot rotate at different speeds (or one is stationary while the other rotates), creating intense relative motion. Within this narrow gap, the cocoa material is subjected to a combination of shearing and friction, continuously breaking down and refining large particles.

Circulating Grinding Path: Inside the grinding chamber, the material moves from the center to the edge along a specific path (such as the spiral grooves of a traditional stone mill) due to the relative motion. During this process, the gaps between the materials may gradually decrease, resulting in continuous grinding and further refinement.
