Tea seed oil squeezing production system and production method

Abstract

The invention discloses a tea seed oil squeezing production system and production method and belongs to the technical field of tea seed oil production. The method comprises the work procedures: husking, screening, drying, winnowing, evenly mixing, smashing, grinding, water steaming, spreading and cooling, squeezing, deacidifying, washing, decoloring, deodorizing and the like. A drying device utilizes an upwards convex reversed-V-shaped net plate, so that a heat exchange area is enlarged, hot wind distribution is facilitated, and convenience is brought to discharging; the drying device utilizesa plurality of sub drying cabins which are arranged side by side, so that not only is processing capacity improved, but also camellia seeds with different moisture contents can be independently treated to ensure a drying effect; the drying effect can be ensured by arranging an up-down hot wind inlet and an up-down air outlet and utilizing a special drying process. According to the method, the work procedures of drying, evenly mixing, squeezing oil, refining and the like are improved; thus, an oil yield can be improved by 2% or more, essential oil can meet a GB11765-2003 primary standard, an effect of removing malonaldehyde, benzopyrene, phosphorus and the like is obvious, and vitamin E, unsaturated fatty acid can be more kept.

Description

technical field [0001] The invention belongs to the technical field of tea oil production, and in particular relates to a production system and production method of pressed tea seed oil. Background technique [0002] Edible oil is a necessary consumer product for people's life, and it is an important food that provides human body heat energy and essential fatty acids, and promotes the absorption of fat-soluble vitamins. With the rapid development of my country's economy and the substantial improvement of people's living standards, people's requirements for the quality and quantity of edible oil are also constantly improving. Eating natural, green and healthy oil products has become an important requirement for people to choose edible oil. Tea seed oil is derived from the woody plant tea tree, which is mainly distributed in the hilly areas of Hunan, Guizhou, Jiangxi, Guangxi, Anhui, Sichuan, Shaanxi and other provinces. It is far away from urban "three wastes" pollution sour...

Problems solved by technology

[0025] For method 1, the drying temperature is higher, which will increase the acid value and peroxide value of Camellia oleifera; at the same time, the oil yield of this method is low, which can generally reach 18-20%; for method 2, in the low-temperature drying process, the thickness is less than The processing capacity of 80cm is small, and the moisture content of camellia seeds after drying is low, which is not conducive to cold storage and consumes a lot of energy; in the hydraulic pressing step, the oil yield is low, generally reaching 19-22.5%, crude oil The moisture content is high, generally greater than 5mg / kg, resulting in turbidity and darker color of the product; in the rough filtration and fine filtration steps, a large amount of diatomaceous earth is used, and the fine filtration effect is not good
