Problems solved by technology

[0003] However, in the existing tea oil production process, high-temperature steaming and multiple refining processes are required to reach the edible quality standard of tea seed oil, which not only affects the nutritional value of tea seed oil, but also has harmful effects during high-temperature steaming and frying. Substance residues, chemical additives will be added in the multiple refining process, resulting in residues of acid, alkali, heavy metals, etc., the loss of nutrients in tea seed oil is large, and the oil yield is low

Embodiment 1

[0020] Embodiment 1, a kind of double-screw low-temperature pressing production method of camellia oil comprises the following steps:

[0021] a) Drying at low temperature: screen the tea seeds and remove impurities, then dry the tea seeds with a flat-panel dryer and an exhaust fan at a drying temperature of 45°C and a drying time of 55 minutes. The dried tea Seed moisture content 6%;

[0022] b) Shelling and separation: the above-mentioned dried tea seeds are shelled by an impeller sheller, and the tea seeds are broken by the force generated by the blade rotation moment, and separated by a cyclone under centrifugal force, gravity and negative pressure The device (shake cage) separates the shell and kernel to obtain clean tea seed kernel;

[0023] c) Pressing at low temperature; the obtained tea seed kernels are squeezed by a press to obtain tea seed oil; the press is a double-screw press, and the tea seeds are put into the press chamber at normal temperature through a double...

Abstract

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 retain the pure natural quality of the tea-seed oil, and as much as possible retains physiological characteristic substances in the tea oil, such as vitamin E, gamma-linolenic acid and other beneficial components.

Description

technical field [0001] The invention relates to a production method of camellia oil by double-screw low-temperature pressing. Background technique [0002] Because of its golden or light yellow color, pure quality, clear and transparent, fragrant smell and pure taste, tea oil does not contain erucic acid, cholesterol, aflatoxin and other harmful substances to the human body, so it can be used as a solvent for intravenous infusion oil or medicine. Camellia oil contains specific physiologically active substances tea polyphenols and camellia glycosides, which can effectively improve cardiovascular and cerebrovascular diseases, lower cholesterol and fasting blood sugar, inhibit the rise of triglycerides, and have obvious effects on inhibiting cancer cells. Therefore, camellia oil is the pure natural woody edible vegetable oil promoted by the Chinese government, and also the health care vegetable edible oil recommended by the International Food and Agriculture Organization.
