<p>Chocolate is refined by so-called conching. This is carried out in a device whereby the mass is spread out in a thin film and exposed to the air. Among other things, the viscosity is reduced as a result. By subjecting the chocolate mass directly prior to the spreading in a thin film to high shear stresses, a further reduction in viscosity takes place. The invention provides a device wherein, directly preceding the spreading out in a film, the mass is subjected to high shear stresses by means of arranging radially directed pins (9) on a drive shaft (2).</p> |
