Zusammenfassung:The invention relates to a preparation method for tea oil by double helix low-temperature squeezing, which comprises the following steps: a) drying at low temperature; drying screened tea seeds by a flat dryer and an induced fan, wherein the drying temperature is 45-55 degree C, the drying time is 55-65 minutes, and the moisture content of dried tea seed is 6-10%; b) husking for separation; c) squeezing at low temperature; d) making squeezed oil stand for filtration; e) performing winterization treatment; and f) obtaining the finished product. Through low-temperature drying, squeezing by a double helix squeezer as well as the filtration technology by standing, the preparation method disclosed by the invention can avoid overheating and excessive chemical treatment to the oil, avoid residues of harmful substances generated during high-temperature processing, and avoid residues of acid, alkali and heavy metals due to addition of chemical addition agents; in addition, the technology disclosed by the invention can
