Abstract
A refiner for mixtures and suspensions having a non-Newtonian rheological characteristic, such as chocolate, which comprises a plurality of power driven refining rollers, and a means of changing the pressure thereof on the respective supports, wherein a means is also provided which is effective to change the actual crowning of the rollers, or the effect of an equivalent crowning, as well as a means of changing the speed of said refining rollers. The crown change is achieved by having the individual rollers supported on an oscillating support adapted to oscillate its respective roller relatively to the associated roller by rotation about an orthogonal midaxis with respect to the roller longitudinal axes, thereby a contact point is established at the roller middle area or circumference while their ends are offset. The speed of the refining rollers is changed through independent and individually operated controls, such as a DC motor. By changing the pressure, crowning, and speed of the rollers, either individually or in combination, the machine may find universal applicability to different viscosity products in desired conditions.
