A wiping device includes a rod, a spraying assembly, a base, and a translation module. The wiping paper is wound around the rod. The spraying assembly comprises a nozzle. The nozzle is arranged above the rod, and the nozzle is arranged towards the wiping paper. The base is used for fixing a workpiece. The translation module is coupled to the rod or the base. When the rod rotates around an axis of the rod, a wiping paper is wound around the rod. The nozzle could spray a cleaning agent to the wiping paper, then, the translation module could drive the rod and the base to move relatively, and the wiping paper wetted by the cleaning agent wipe the workpiece. The cleaning agent could wet the outermost layer of the wiping paper directly, so that the amount of the cleaning agent could be reduced.

A liquid discharge apparatus includes a liquid discharge unit and a contact detection unit. The liquid discharge unit has a liquid discharge port from which a liquid is discharged toward an object. The liquid discharge unit is movable along at least one of a first axis and a second axis intersecting the first axis and movable along a third axis intersecting the first axis and the second axis. The third axis is parallel to a direction in which the liquid is discharged from the liquid discharge port toward the object. The contact detection unit detects contact of the liquid discharge unit with the object. The contact detection unit is detachably attached to the liquid discharge unit.

An apparatus for cleaning a food-processing machine having cylindrical rolls disposed along a curve, each of the rolls having a peripheral working surface for contacting food products and an axis about which each roll rotates. A drive rail is mounted parallel to the axes of the rolls and extends the length of the rolls. A spray bar slidably mounts to the drive rail, extends adjacent the rolls, and has at least one nozzle for spraying liquid onto the working surfaces of the rolls to clean them of debris. A prime mover drives the spray bar along the drive rail parallel to the axes of the rolls while spraying the rotating rolls.
