Egg brushing machine

The invention discloses an egg brushing machine which comprises a rack, wherein a driving device, a brush length change mechanism and a baking tray rotating mechanism are mounted on the rack; the driving device, the brush length change mechanism and the baking tray rotating mechanism are arranged from top to bottom in sequence; and the driving device drives the brush length change mechanism to move in a vertical direction and a horizontal direction. When a baking tray is moved to the baking tray rotating mechanism, an egg liquid is firstly brushed transversely, and a food is repeatedly coatedby the egg liquid transversely; later the baking tray is rotated, the length of the brushing part of the brush length change mechanism is controlled to be changed by a system, the egg liquid is brushed longitudinally, and the process and method of longitudinally brushing the egg liquid are generally identical to those of transversely brushing the egg liquid; and after the operation of longitudinally brushing the egg liqui
