Problems solved by technology

For example, Chinese patent CN1468948 discloses a new refining process of tea seed salad oil, and Chinese patent CN101892125A discloses a high-efficiency winterization equipment and winterization method for tea oil. These technologies all adopt the winterization process, which increases the input of equipment And process operation, increase cost, and is not conducive to energy saving and consumption reduction

Embodiment 1

[0020] The method for refining tea seed oil of the present invention, comprises the steps:

[0021] Pump 1000kg of tea seed oil crude oil into the degumming tank, add 1.5kg of food grade citric acid degumming agent, stirring speed is 100r / min, degumming temperature is 35°C, degumming time is 40min, let stand for 1 hour, and then discharge the lower water layer; Pump the degummed tea seed oil into the deacidification tank, add 5 kg of food-grade sodium hydroxide deacidification agent with a concentration of 25%, the temperature is 30 °C, the time is 25 min, the stirring speed is 100 r / min, and then the temperature is raised to 70 °C, static Set aside for 1 hour, drain the saponins, etc.; wash the oil with 30kg of hot water at 90°C each time, the oil temperature is 85°C, and the stirring speed is 90 r / min until the pH value of the water layer is equal to 7; pump the washed tea seed oil Put it into the dehydration tank, raise the temperature to 100°C, and the vacuum degree is 0.0...

Embodiment 2

[0024] Pump 800 kg of tea seed oil crude oil into the degumming tank, add 1.0 kg of food grade citric acid degumming agent, the stirring speed is 90r / min, the degumming temperature is 30°C, the degumming time is 40min, let stand for 1 hour, and then discharge the lower water layer; Pump the degummed tea seed oil into the deacidification tank, add 4.0kg of food-grade sodium hydroxide deacidification agent with a concentration of 25%, the temperature is 30°C, the time is 20min, the stirring speed is 110 r / min, and then the temperature is raised to 70°C, static Set aside for 1 hour, drain the saponins, etc.; wash the oil with 30kg of water, 90°C hot water, the oil temperature is 85°C, and the stirring speed is 80 r / min, until the pH value of the water layer is equal to 7; pump the washed tea seed oil into the dehydration tank, heated to a temperature of 100°C, and a vacuum degree of 0.09MPa, for drying and dehydration; the dehydrated tea seed oil was pumped into the decolorization...

Abstract

A method for refining tea seed oil includes taking tea seed oil crude oil as a raw material, and producing refined tea seed oil by processes of degumming, deacidifying, washing, decoloring, deodorizing and precisely filtering. Precise filtration is used for removing wax and other substances, and takes the place of the conventional winterization in tea seed oil refining production technology. The product reaches the quality using the winterization technology. The method helps to simplify the production process, reduce equipments and facilities needed for winterization, and reduce the production cost.

Description

technical field [0001] The invention relates to the field of oil processing, in particular to a method for refining tea seed oil. Background technique [0002] Camellia oleifera belongs to the family Theaceae Camellia, and is known as the world's four major woody oil plants together with olive, oil palm, and coconut. It originated in China and has a history of cultivation and utilization for more than 2,000 years in my country. It is mainly distributed in the Yangtze River Basin and its south 14 provinces (autonomous regions, municipalities) of China. [0003] Camellia oleifera fruit oil obtained by pressing or extracting is tea seed oil. The chemical composition and fatty acid ratio of tea seed oil are similar to olive oil, and some indicators are higher than olive oil. It is known as "Oriental olive oil". Tea seed oil is resistant to storage, not easy to rancidity, does not produce carcinogenic aflatoxin, and is rich in a variety of natural vitamins and trace health-care n...
