Apparatus for continuous tempering of chocolate mass comprising a column of elements (3) each having a mass chambers (4) and an intermediary water chamber (5). A central drive shaft (6) is in engagement with mixing elements (7, 23, 24) arranged in the mass chamber (4). A sun gear wheel (14) is arranged in the mass chamber with its hub (15) engaged on the shaft (6). An internal ring gear (16) is arranged extending along the inside (17) of the peripheral wall (11) of the mass chamber (4). The mixing elements (7, 23, 24) comprise intermediary planet wheels (18), which mesh with the sun gear wheel (14) and with the internal ring gear (16). The planet wheels (18) carry mixing elements (7) in the form of lower and upper mixers (23, 24), which provide planetary movements through the mass chambers. The mixing, scraping and shear is effective and even in all parts of the mass chambers. The tempering apparatus is then made smaller than the prior art apparatus.
