Process for hard panning of chewable cores and cores produced by the process
First Claim
1. A process for the production of chewable coated cores comprising the hard panning of chewable cores in a coating pan or drum wherein a syrup containing at least one of a crystallizable polyol, a crystallizable sugar or mixtures thereof is intermittently sprayed over a rotating bed of the cores and said cores are dried between sprayings with a flow of air, said cores being dried between sprayings by controlling effective parameters of said drying air selected from the group consisting of air humidity, air temperature, air flow speed, air flow time, air flow direction and any combination thereof and stopping said drying before the relative humidity of the outlet flow of drying air has reached its basic level at which its gradient has flattened to a plateau, so as to cause a substantial residual moisture to remain in the drying coating layer at the start of a subsequent spraying phase.

Abstract
The invention relates to a process for the hard panning of chewable cores in a pan or drum wherein a syrup of a crystallizable sugar or polyol is intermittently sprayed over a bed of the cores and the cores are dried between sprayings with a flow of air. The speed and efficiency of the panning process is increased by controlling the drying of the cores between sprayings by controlling parameters of the drying air in such a way as to intentionally leave a substantial residual moisture in the drying coating layer at the start of a subsequent spraying phase. The chewable products are preferably xylitol coated chewing gums.

28. A process for the production of chewable coated cores by hard panning comprising:
-
spraying a syrup containing at least one of a crystallizable polyol, a crystallizable sugar and combinations thereof over a rotating bed of chewable cores in a coating pan or drum;
stopping said spraying of said rotating cores while continuing rotation;
starting to dry said cores with an inlet flow of air;
controlling the drying of said rotating cores by controlling effective parameters of the drying air selected from the group consisting of air humidity, air temperature, air flow speed, air flow time, air flow direction and any combination thereof;
stopping said flow of drying air at a point before the relative humidity of the outlet flow of said drying air has reached its basic level at which its gradient has flattened to a plateau indicating that a substantial residual moisture remains in the drying coating layer;
starting a subsequent spraying phase by spraying said syrup onto the moisture containing layer of the previous spraying phase; and
repeating the spraying and drying of said rotating cores until a predetermined coating has been provided.
