Abstract

Methods, apparatuses, and systems for removing the peels/skins from agricultural produce, such as fruits and vegetables, are disclosed. The peel and/or the connection between the peel and the flesh of the produce can be at least partially destroyed by a caustic fluid and/or steam. Once the peel has been sufficiently loosened from the flesh, forced air may be applied to the surface of the produce to remove the loosened peel and any residual caustic fluid. Using air to remove the loosened peel instead of the conventional use of water significantly reduces the freshwater requirements and substantially reduces the quantity of wastewater discharge with very low concentration of contaminants. The peels, caustic fluid, and water can be collected and separated, after which the peels can be neutralized and fed to livestock, used as fertilizer, or used for pectin production, and the caustic fluid and residual water can recycled into the system.
