Embodiment 1

[0067] Embodiment 1 provides a kind of production system of pressing tea seed oil, see figure 1 and 2 , the system includes a pretreatment section, an oil extraction section and a refining section; the pretreatment section is used for shelling, screening, drying and winnowing of Camellia oleifera seeds; the oil extraction section is used for low-temperature extraction to obtain crude oil; the refining section It is used to refine crude oil to obtain tea seed oil exceeding the national standard (GB11765-2003) of camellia seed oil pressed primary oil. The pretreatment section includes a shelling device, a screening device, a drying device, and a wind separation device 6 that are sequentially connected through a conveyor belt or a bucket elevator (for example, a third bucket elevator 5 is installed between the drying device and the air separation device 6). and mixing device, etc., can be located in the same workshop (drying workshop); the oil extraction section includes crushin...

Embodiment 2

[0082] Embodiment 2 provides a production method of pressed tea seed oil. The method includes a pretreatment section, an oil extraction section and a refining section, and the pretreatment section includes steps such as shelling, screening, drying and winnowing in sequence. Wherein, the drying process includes drying the moisture content of the camellia seed to 8-10% by using a drying device.

[0083] Among them, see Figure 12 , the oil pressing section includes the following processes:

[0084] 201 Pulverization: using a pulverization device to pulverize the Camellia oleifera seeds from the pretreatment section or refrigerated after being treated in the pretreatment section to a size of 0.15-0.25 mm, to obtain Camellia oleifera seed powder and send to step 202.

[0085] 202 Rolling: use a rolling device to roll the camellia seed powder processed in step 201 to 0.05-0.15 mm, and send to step 203. The rolling process can increase the oil yield of crude oil by 1-2%, and facil...

Embodiment 3

[0103] Embodiment 3 provides a kind of production method of pressing tea seed oil, and the method comprises the following steps:

[0104] Among them, see Figure 11 , the pretreatment section includes:

[0105] 101 Shelling: the shelling device is used to break the shell to separate the nuts.

[0106] 102 Screening: Use a screening device (such as a vibrating screen) to separate the shells, so that the shell rate in the camellia seed kernel is below a certain value.

[0107] 103 Drying: Lay tea oil seeds in the drying chamber with a thickness of 2m and an inverted V-shaped mesh plate 11 with a height of 0.5m; in the first 6 hours, the feed and upper exhaust port 19 are opened, and the lower exhaust port 14 is closed. The upper hot air inlet 16 is closed, the lower hot air inlet 17 is fed with 30°C hot air; after 2 hours, the feed and upper exhaust port 19 are closed, the lower exhaust port 14 is opened, the upper hot air inlet 16 is fed with 30°C hot air, and the lower hot a...

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...
