Embodiment 1

[0038] The processing and refining process of the tea seed oil of the present embodiment may further comprise the steps:

[0039] (1) Select mature tea seeds, use far-infrared vacuum drying to a water content of 4%, and send the dried tea seeds to the shelling machine for shelling;

[0040] (2) Pass the dehulled tea seeds into 50°C atomized water for conditioning, and pass through the atomized water while stirring. The temperature of the conditioned tea seeds is 65°C, the water content is 6%, and the material is cooled;

[0041] (3) Put the conditioned tea seeds in a baking box to bake;

[0042] (4) After the baking is finished, let the tea seeds stand at room temperature for 20 minutes;

[0043] (5) Put the tea seeds treated in step (4) into the baking box for roasting again, and spray water twice during the roasting process;

[0044] (6) Use a screw press to press the roasted tea seeds, the temperature of the pressing chamber is 80°C, and the temperature of the oil outlet ...

Embodiment 2

[0063] (3) Put the conditioned tea seeds in a baking box to bake;

[0064] (4) After the baking is finished, let the tea seeds stand at room temperature for 30 minutes;

[0065] (5) Put the tea seeds treated in step (4) into the baking box for roasting again, and spray water twice during the roasting process;

[0066] (6) Use a screw press to press the roasted tea seeds, the temperature of the pressing chamber is 110°C, and the temperature of the oil outlet is ...

Embodiment 3

[0082] The processing and refining process of the tea seed oil of the present embodiment may further comprise the steps:

[0083] (1) Select mature tea seeds, use far-infrared vacuum drying to a water content of 5.5%, and send the dried tea seeds to the shelling machine for shelling;

[0084] (2) Pass the dehulled tea seeds into 50°C atomized water for conditioning, and pass through the atomized water while stirring. The temperature of the conditioned tea seeds is 70°C, the water content is 8%, and the material is cooled;

[0085] (3) Put the conditioned tea seeds in a baking box to bake;

[0086] (4) After the baking is finished, let the tea seeds stand at room temperature for 25 minutes;

[0087] (5) Put the tea seeds treated in step (4) into the baking box for roasting again, and spray water twice during the roasting process;

[0088] (6) Press the roasted tea seeds with a screw press, the temperature of the pressing chamber is 95°C, and the temperature of the oil outlet ...

Abstract

The invention relates to the technical field of oil refining, in particular to a processing and refining process of tea seed oil, which comprises the following steps of: (1) drying by adopting far infrared vacuum method until the water content of tea seeds is 4-7% by mass; (2) introducing atomized water into the dehulled tea seeds for conditioning; (3) placing the tea seeds in a baking box for baking; (4) standing; (5) baking in a baking box; (6) squeezing the baked tea seeds by a screw squeezer; (7) removing impurities by a closed filter; (8) distilling; (9) deacidifying; (10) primary decolorizing; (11) secondary decolorizing; (12) vacuum drying; (13) fine-filtering. The process has high oil yield and high oil nutritive value, physical refining process is used, damage to oil quality and environmental pollution in the chemical refining process is avoided, the process has the advantages of few preparation steps, simple operation, low energy consumption and high product quality.

Description

technical field [0001] The invention relates to the technical field of oil refining, in particular to a processing and refining process of tea seed oil. Background technique [0002] Camellia oleifera originated in China. It is the main woody edible oil tree species unique to southern my country and one of the four largest woody edible oil tree species in the world. The area of ​​Camellia oleifera forests in my country accounts for more than 80% of the woody edible oil plant area. The oil obtained from tea seeds is tea seed oil. The fatty acid composition of tea seed oil is similar to that of high-grade edible oil-olive oil. Its unsaturated fatty acid content exceeds 80%, which has high nutritional value; no chemical fertilizers are applied during the planting of camellia oleifera and pesticides, so tea seed oil belongs to natural green food. A variety of functional components in tea seed oil have obvious effects on maintaining the function of the cardiovascular system, imp...
