    Abstract: A method is shown for producing food grade hydrated lime. A source of raw, hydrated lime is first passed through a classification step which divides the raw hydrated lime into a first fine stream and a first coarse stream. The first fine stream is passed through a further separation step and, without being recombined with the first coarse stream is separated out to form a very fine sized product which meets CODEX chemical specifications. The additional separation step may be a wet process and may utilize a hydrocyclone type separator.

  • Patent number: 6926879
    Abstract: A method is shown for producing food grade hydrated lime. A source of raw, hydrated lime is first passed through a classification step which divides the raw hydrated lime into a first fine stream and a first coarse stream. The first coarse stream is then passed to a grinder which produces a ground coarse product. The first fine stream is separated out from the first coarse stream and, without combining the first fine stream with the first coarse stream or with the ground coarse product, is removed to produce a very fine sized product which meets CODEX chemical specifications.
