Problems solved by technology

Since the electric oven is installed in the baking powder cavity, the whole baking powder device takes up a large space and has a complicated structure; because the temperature of the powder tube needs to be accurate, but the electric heating oven is set in the baking powder cavity, the temperature accuracy control is not high; the slurry is dry The speed is slow and the slurry does not flow or the flow speed is slow, making the thickness of the entire slurry uneven

Abstract

The apparatus includes apparatus of coating powder and apparatus of baking powder (ABP). ABP includes cavity of baking powder, and heating system outside the cavity. Power tube with powder slurry being coated is positioned in rotation mechanism inside the cavity. The rotation mechanism drives rotation of power tube. The heating system possesses air duct passing through the cavity to inside from outside. The method includes coating procedure and baking procedure. The baking procedure includes steps: (1) positioning step: positioning power tube to the rotation mechanism; (2) operating step: rotation mechanism drives rotation of power tube; through air duct, the heating system whiffs hot air to power tube in order to dry powder slurry, and make powder slurry attach to inner wall of the powertube. The heating system is separated from the cavity. Features are: simple structure of ABP, controlling temperature of ABP accurately, quick drying speed, and even thickness of powder slurry.

Description
