Tea oil leaching production method and special equipment thereof

Abstract

The invention discloses a tea oil leaching production method, comprising the following steps: a, leaching: loading raw materials into a leaching pot and adding a solvent with perfluoro-n-butane content being 90%, wherein the material loading amount is 80% of the volume of the pot, the volume ratio of the raw materials to the solvent is 1: 2, the leaching time is 120min and the leaching temperature is 50 DEG C; and b, evaporative separation: evaporating the mixed oil leached in the above step in an evaporation pot, wherein the solvent in the mixed oil is gasified and then extracted by a compressor until the residual solvent in the oil is below 50PPm. The tea oil leaching production method also comprises a solvent backflow step. The invention also discloses tea oil leaching special equipment. By using perfluoro-n-butane as the solvent, the tea oil leaching production method provided by the invention is free of explosion and fire dangers; the oil is leached at normal temperature, so thatthe degeneration of protein is decreased and the obtained finished oil is light in color and high in quality; and as no additional heat is used during the solvent evaporation, the heat energy consumption is reduced. As solvent backflow is adopted, the solvent can be recycled and the cost is reduced.

Description

technical field [0001] The invention relates to a tea oil extraction production method and special equipment thereof. Background technique [0002] The current leaching process of camellia oil production is to use No. 6 solvent or industrial n-hexane to extract the oil in the oil. Its main disadvantages are as follows: first, No. 6 solvent and n-hexane are flammable and explosive, and there are great safety hazards; second, the protein and active substances in the oil are denatured by heating or oxidatively degraded, which not only reduces the use value, but also returns to the follow-up Refining increases the difficulty. The 3rd, solvent heating evaporates, and heat energy consumption is big. Contents of the invention [0003] The object of the present invention is to provide a tea oil extraction production method that can improve the safety of the extraction process, reduce protein denaturation, and reduce heat energy consumption. Also provided is a kind of production...
