MANUFACTURING PROCESS OF SPHEROIDAL FOOD DYES

摘要

The process of manufacturing spheroidal shaped granules using mixture of liquid food colour (i.e. FD and C dyes, acid dyes, D and C dyes, synthetic dyes and blends of synthetic dyes) which is first spray dried, then pulverized, then blended with water to form noodles which are cut into an uniform size. These uniform sized noodles are then subjected to a spherodizer containing a bowl with a plate bottom wherein the noodles are subjected to a centrifugal action which makes the noodles to collide with the wall of the bowl and return back. This continuous action of hit and cut transforms the noodles into spheroidal shaped granules which are then dried and sieved in a vibratory sifter to obtain spheroidal granules having, high rate solubility, do not disintegrate into dust form, are easier to handle.
