The K&K TWO ROLL REFINER for chocolate is designed with the latest technology. Two roll refiner can be used as pre-finer before five roll refiner or stand alone refiner with multiple refining process. The crushing of chocolate ingredients between the two grinding rolls makes possible to use crystal sugar instead of powder sugar. In this way it is possible to eliminate the humidity in chocolate. Prerefiner reduces the prepared mix from 600-1000µ to 80-130µ grain thickness. It forms very well tissue with raw material’s molecules and oils. This operation improves the adhesive capability to the refiner cylinders. It lowers conche period. Prerefiner thins products with compact hydrostatic pressure system. Capacity is 10-60 kg/h.
