Problems solved by technology

[0004] The prolongation of harvesting and pretreatment time, such as long-term natural drying, leaching and steaming and frying processes will cause a large amount of free fatty acids in the oil, which will increase the acid value, resulting in a large amount of peroxides in the oil, making subsequent processing necessary. The chemical refining process requir

Example Embodiment

[0016] Example 1

[0017] A processing technology of squeezing tea oil includes the following steps:

[0018] (1) Picking and picking: picking and picking mature tea seeds, picking out mildew and deflated tea seeds, this step is completed within 20 hours; tea seeds are camellia seeds or tea seeds;

[0019] (2) Drying and dehulling: the picked tea seeds are dried by microwave vacuum to 9% moisture content, and the dried tea seeds are sent to the dehulling machine for dehulling. The dehulling rate is over 99%. Tea seed is dehulled, so that the hull content in the tea seed kernel is less than 0.4%; the dehulled tea seed is dehulled by winnowing and dehulling;

[0020] (3) Cold pressing: The dehulled tea seeds are put into a cold press for cold pressing to obtain tea oil. The oil output temperature of the cold press is lower than 90°C, and the oil output rate is controlled at 80%;

[0021] (4) Removal of impurities: The squeezed tea oil is passed through a tympanic membrane plate and frame...

Abstract

The invention discloses a processing technology of pressed tea oil, the processing technology comprises the following steps: (1) selecting and picking; (2) drying and shelling; (3) performing cold pressing; (4) removing impurities; (5) settling; and (6) guiding the oil. According to the method disclosed by the invention, the pre-treatment time after the picking is controlled, the pre-treatment process is completed within 20 hours after the picking, and oxidative deterioration of fatty acids in tea seeds is effectively prevented. The tea seeds are dried under the conditions of low temperature and high vacuum degree by adopting a vacuum microwave drying mode, the combination of the fatty acids and proteins in tea seed kernels is destroyed by virtue of oscillation action of microwaves, the precipitation of fatty glyceride is promoted, the oil yield in the cold pressing process is improved, and under the low temperature and vacuum state, the acid price increase and peroxide product increase caused by high temperature and oxygen are reduced, and the difficulty of the subsequent processing technology is reduced.

Description

technical field [0001] The invention relates to a processing technology of pressed tea oil. Background technique [0002] Camellia seeds and tea seeds are the seeds of Camellia oleifera and tea leaves, and are one of the oldest traditional woody edible vegetable oils in my country. Their fatty acid composition is very reasonable, and they contain tea polysaccharides, saponins, flavonoids, tea polyphenols, and vitamins. and phytosterols and other nutritional and functional active substances. Regular consumption of tea seed oil has the effects of reducing three highs, improving immunity, anti-radiation, scavenging free radicals, and preventing tumors. It is a healthy edible oil and a topical oil for health care. [0003] At present, the extraction process of tea seed oil basically adopts leaching or steaming, frying and pressing, and the refining process of crude oil basically adopts hydration degumming-alkali refining and deacidification-water washing-filtration decolorization...
