This creation illustrates a kind of automatic spraying system using what food, and it includes having a conveyer belt, a spraying equipment and a cooling equipment, wherein conveyer belt is for conveying food materials. Spraying equipment is on the top and the front the slurry being in a liquid state to be sprayed to what food materials for set what conveyer belt to form a coating layer. Cooling equipment be include a vortex tube, vortex tube generates cold air and hot-air using compressed air, and vortex tube also has a cold-air vent, and cold-air vent is directed toward food materials with cooling upper coating layer. By the automatic spraying system of this creation, on what processing procedure, the step of forming coating layer, is less, and without using other more expensive cooling equipment, can reduce entirety manufacturing cost.本創作說明了一種應用於食品的自動化噴塗系統，其包含有一輸送帶、一噴塗設備與一冷卻設備，其中輸送帶是用來輸送食材。噴塗設備是設於輸送帶的上方並用以將呈液態的漿料噴塗於食材的正面上以形成一披覆層。冷卻設備是包含有一渦流管，渦流管利用壓縮空氣而產生冷空氣與熱空氣，渦流管還具有一冷空氣出口，冷空氣出口指向食材以冷卻上披覆層。通過本創作的自動化噴塗系統，於製程上，形成披覆層的步驟較少，而且無需使用其他比較昂貴的冷卻設備，能降低整體製造成本。
