Kit assembly of parts adapted for modifying an apparatus for continuous tempering of chocolate mass having a crystallisation stage (B) and arranged as a tempering column of stacked elements.The kit comprises a device part (82) having a first end and a second end, seen in the flow direction of the chocolate, and a primary conduit for chocolate mass extending between the two ends, a pump (81) adapted to pump the chocolate through the conduit,and a first and a second disc-shaped element (83, 84) adapted to substitute two disc-shaped elements of the tempering column, so that the first end is connected to the first disc-shaped element and the second end is connected to the second disc-shaped element, and so that the primary conduit is by-passing the stage (B) for creating crystals.The performance of an existing tempering column may then be improved in a very simple and economical manner.The apparatus becomes especially energy-saving and has increased capacity.
