Abstract
A spray device is used to deliver a liquid, liquid containing a solid or a solid in a shaped flow onto a surface. The spray device can be used to deliver the material downwardly, laterally or upwardly in the form of droplets, a curtain or a mist. The spray device consists of a housing which uses a center shaft to deliver the material from the feed end to the discharge end. At the discharge end this center shaft has a flange which rotates with the center shaft. This flange is adjustable. Disposed over this center shaft flange is a flange fixedly attached to the nozzle housing. The material that is being delivered is shaped into the desired form in this flange region of the spray device. This spray device is non-clogging. In a preferred embodiment the surface that is being coated is the surface of an edible food product such as a cookie, biscuit, cracker or candy. The coating can be an oil, an oil containing dissolved or suspended flavorants, or a confection such as chocolate.
