Venturi-driven flotation separator for chili peppers

Mechanically harvested chili-pepper plants are sized into chunks and introduced into a water flotation system. Water is added at the top of a flotation vat and, for the most part, is withdrawn at the bottom using a venturi unit. The balance of the water is recovered as spillover from the top of the vat carrying the floating material. If the rate of water withdrawal at the bottom of the vessel is controlled such that it is as high as possible but less than what produces turbulence in the vat, the pulp material will drop with heavy seeds to the bottom with the extracted water while all other materials are skimmed away at the top. The very small differential in density between the pepper pulp and the rest of the plant and debris is sufficient to separate them under these specific conditions.
