PCT No. PCT/DK94/00257 Sec. 371 Date May 15, 1996 Sec. 102(e) Date May 15, 1996 PCT Filed Jun. 23, 1994 PCT Pub. No. WO95/00031 PCT Pub. Date Jan. 5, 1995An agglomerated powder is produced in an apparatus where the product is agglomerated in two stages. First, a liquid concentrated feed of the product is atomized by an atomizer in a drying chamber. The fine particles are transferred to a separating device to be split up in a first and second fraction. The first of these is led to the atomizer in the drying chamber to perform a first agglomeration and the resulting agglomerates are accommodated in an external fluid be in the drying chamber and from this transferred to an external fluid bed. Also the second fraction is transferred to the external fluid bed where water by a second atomizer is atomized over a fluidized layer of agglomerates to perform a second agglomeration of product. |
