Abstract: An apparatus for providing a crystalline powder of a material, comprising: an evaporator (10); a crystallizer (20); and a dryer (30), and further comprising: a heat pump (40) comprising: a cold heat exchanger (41); a hot heat exchanger (42); and a very hot heat exchanger (43) and being adapted to exchange heat energy with a second circuit (50) comprising: a condense heat exchanger (55) connected to the cold heat exchanger (41) and the evaporator (10); a crystallization heat exchanger (52) connected to the cold heat exchanger (41) and the crystallizer (20); a pre-heat and a main-heat heat exchanger (53, 54) connected to the hot and very hot heat exchangers (42, 43) and a hot air inlet (31) of the dryer (30), and the apparatus comprising an additional external heat sink (60) and/or a solvent heat exchanger (51) and/or an external source (70) to provide additional heating to the inlet air upstream of the hot air inlet (31) of the dryer (30), and whereby the heat pump (40) and second circuit (50) is configured to fulfil the cooling needs of the crystallizer (20).
