VERFAHREN ZUM AUFBRINGEN VON STOFFEN AUF EXPANDIERTE, STAERKEHALTIGE PRODUKTE

摘要

The invention relates to a process and apparatus for applying matter to expanded starch-containing products, it being possible to use the process in the foodstuffs industry. The process according to the invention can be used, in particular, in the preparation of starch-containing products known as snacks for applying spices or other matter. The expanded starch-containing product is, immediately after expansion, placed in a reaction chamber where it is exposed to the earth's gravity or a centrifugal field. During this, a gas/vapour mixture flows into the reaction chamber at a high velocity approximately at right-angles to the direction of action of the field. The matter to be applied to the surface of the expanded starch-containing product is introduced together with the gas/vapour mixture into the reaction chamber. In the expansion chamber a velocity component opposite to the direction of the field is imposed on the gas/vapour flow.
