Embodiment 1

[0022] This example provides a production method of tea seed blended oil, which includes producing crude oil, alkali refining, water washing, deodorization and winterization filtration to produce crude oil, using tea kernels with a purity of 98% and a moisture content of 7%. Rapeseed with 8% water content is 80% by weight: 20% ratio to obtain a mixture, use a mixer to stir the obtained mixture evenly with a stirring speed of 30r / min and a stirring time of 8min, and mix the stirred Send the mixture to the steaming wok so that the heating temperature of the heat transfer oil in the steaming wok is 40°C. When the skin temperature of the mixture reaches 40°C, steam and fry at a stirring speed of 38r / min for 28min. The mixture is squeezed out by a double-screw low-temperature press at a speed of 50r / min, and then filtered through a plate-and-frame filter press to obtain crude oil; for alkali refining, lye is added to the crude oil at an initial temperature of 30°C within 8 minutes. ...

Embodiment 2

[0024] This example provides a production method of tea seed blended oil, which includes producing crude oil, alkali refining, washing, deodorization and winterization filtration to produce crude oil, using tea kernels with a purity of 92% and a water content of 8%. Rapeseed with a water content of 10% is 82%: 18% by weight to obtain a mixture. Use a stirrer to stir the obtained mixture evenly with a stirring speed of 26r / min and a stirring time of 6min. The stirred The mixture is sent to the steamer, so that the heating temperature of the heat transfer oil in the steamer is 43°C. When the skin temperature of the mixture reaches 38°C, steam and fry at a stirring speed of 36r / min for 25min. The mixture is squeezed out by a twin-screw low-temperature press at a speed of 47r / min, and then filtered through a plate-and-frame filter press to obtain crude oil; for alkali refining, lye is added to the crude oil at an initial temperature of 28°C within 7 minutes. Sodium hydroxide with ...

Embodiment 3

[0026]This example provides a production method of tea seed blended oil, which includes producing crude oil, alkali refining, water washing, deodorization and winterization filtration to produce crude oil, using tea kernels with a purity of 100% and a moisture content of 7.5% Rapeseed with a water content of 9% is mixed with a ratio of 76:24% by weight to obtain a mixture. Use a mixer to stir the obtained mixture evenly with a stirring speed of 32r / min and a stirring time of 10min. The material is sent to the steaming wok, so that the heating temperature of the heat transfer oil in the steaming wok is 38°C. When the skin temperature of the mixture reaches 38°C, steam and fry at a stirring speed of 45r / min for 30min, and mix the mixture after steaming and frying. The material is squeezed out by a double-screw low-temperature press at a speed of 53r / min, and then filtered through a plate-and-frame filter press to obtain crude oil; alkali refining, adding lye Baume to the crude oi...

Abstract

The invention provides a production method of tea seed blend oil. 76-83% of tea kernel and 18-22% of rape seed by weight are prepared through crude oil preparation, alkali refining, washing, deodorization and winterization filtration to obtain the tea seed blend oil. The friction force and oil yield can be increased during oil expression, and the problems that the friction force is low during oil expression and consequently the oil yield can only reach about 80% and the raw material increasing the friction force is not favorable for increasing the oil yield of tea kernel oil expression are solved. According to the production method of the tea seed blend oil provided by the invention, the tea seed and rape seed are mixed and squeezed, the tea oil cost is lowered, the tea oil has rich nutrition, the content of vitamin E of the obtained tea seed blend oil can reach 350mg/100g for sure, and the problem that the tea oil has insufficient nutritional ingredients such as vitamin E, arachidic acid and the like is solved; and moreover, the tea seed blend oil is convenient to operate and easy to store and can be stored for a long time.

Description

technical field [0001] The invention relates to a production method of tea seed blended oil. Background technique [0002] In production, when using double-screw low-temperature presses to extract oil from tea kernels, the tea kernels are squeezed and the temperature generated during extrusion makes the tea kernels hard, and if there is no auxiliary material to increase friction, the oil will come out The efficiency can only reach about 80%. If the shell of the tea seed itself is used as raw material to increase the friction, because the oil content of the tea shell is only 1%, the tea shell is very oil-absorbing, which is not conducive to the oil yield of the tea kernel oil. [0003] The unsaturated fatty acid of pure camellia oil reaches more than 90%, oleic acid reaches 80-83%, linoleic acid reaches 7-13%, and is rich in protein and vitamins A, B, D, E, etc., especially it contains Rich linolenic acid is necessary for the human body but cannot be synthesized. The cont...
