Applicator for applying liquid coatings
View Patent ↗The present invention relates to an apparatus for applying stripes of liquid coating on a confectionery product comprising a rotatable applicator for liquid coating, at least one shield positioned above the rotatable applicator to collect coating material not applied onto the product, a manifold for providing the rotatable applicator with the coating material in a liquid form, and wherein the rotatable applicator is arranged to spin about an axis which is orientated from horizontal and up to 30 deg of deviation from horizontal, and wherein the applicator has openings along it's circumference through which coating material may be projected upon spinning of the applicator. The invention also relates to a method for decorating confectionery products and to the products.
1. An apparatus for applying stripes of liquid coating on a confectionery product comprising:
a rotatable applicator for the liquid coating;
at least one shield positioned above the rotatable applicator to collect the liquid coating not applied onto the confectionary product;
a manifold for providing the rotatable applicator with the liquid coating;
the rotatable applicator is arranged to spin about a spin axis which is orientated between 0 to 30 degrees of from a horizontal plane, and wherein the rotatable applicator has openings along a circumference of the rotatable applicator through which the liquid coating may be projected upon spinning of the rotatable applicator; and
wherein the at least one shield positioned above the rotatable applicator comprises a plate oriented at an angle of 40 to 80 degrees as measured from the spin axis of the rotatable applicator and at an angle of 0 to 60 degrees as measured from a horizontal line extending perpendicular to the spin axis of the rotatable applicator into the direction where the confectionary product is located.
2. The apparatus according to claim 1 , wherein the plate comprises one or more flaps oriented with an angle of 20 to 90 degrees as measured from a surface of the plate.
3. The apparatus according to claim 1 , wherein the at least one shield comprises a series of three or more flaps wherein the flaps are oriented vertical or leaning up to 60 degrees in the direction where the confectionary product is located, as measured against a vertical line.
4. The apparatus according to claim 2 , wherein the one or more flaps are oriented parallel to one another.
5. The apparatus according to claim 1 , wherein the rotatable applicator is arranged to turn clockwise and/or counter-clockwise at the spin axis.
6. The apparatus according to claim 1 , wherein the openings are orientated in one or more rows around the circumference of the rotatable applicator.
7. The apparatus according to claim 1 , wherein the openings are oriented in a straight line or in a line that has a curved or zig-zag shape, and/or a distance between the openings is equal or of varying distance to each other.
8. The apparatus according to claim 1 , wherein the openings are of varying diameter and shapes from each other.
9. The apparatus according to claim 1 , wherein the rotatable applicator is capable of rotating at a speed of between 100 and 2500 rpm to project the liquid coating.
10. The apparatus according to claim 1 , wherein the plate comprises one or more flaps, wherein the one or more flaps are bent with each edge of the one or more flaps aligned with a direction of the liquid coating projected onto the one or more flaps.
