Description
Technical Field
The invention relates to the technical field of agricultural product processing, in particular to a method for removing shells of oil-tea camellia fruits.
Background
The tea-oil tree is also called tea tree, tea oil tree, white tea and evergreen small arbor. Its seed is called as oil-pressing food. The seed contains more than 30% of oil, and can be used for eating, hair moistening, medicine preparation, candle and soap, or used as engine oil substitute. Camellia oleifera is commonly known as the world's four woody edible oil plants, together with oil palm, olive and coconut. The tea-oil tree has high comprehensive utilization value, the tea seed meal contains tea saponin, tea seed polysaccharide, tea seed protein and the like, which are raw materials of products in chemical industry, light industry, food industry, feed industry and the like, the tea seed shells can be made into furfural, active carbon and the like, and the gray washing head of the tea tree can kill lice including worm eggs. The tea oil has unsaturated fatty acid content as high as 90%, is much higher than rape oil, peanut oil and soybean oil, has vitamin E content twice as high as olive oil, contains specific physiological active substances such as camellin, and has high nutritive value. The tea shell is also a good edible fungus culture medium. Researches show that the oil tea saponin has antibacterial and antioxidant effects. The tea oil is clear in color, delicious, rich in nutrition and long in storage life, and is high-quality edible oil; can also be used as lubricating oil and antirust oil for industry. The tea cake is not only a pesticide but also a fertilizer, and can improve the water storage capacity of the farmland and prevent and control pests in the rice field. The pericarp is the raw material for extracting tannin extract.
At present, the shelling of the oil-tea camellia fruits is basically carried out manually, the manual shelling efficiency is low, the labor intensity is high, the cost is high, and the method is not suitable for industrial production. The existing shelling treatment process of the oil-tea camellia fruits does not classify the oil-tea camellia fruits in size, but performs mixed processing, in addition, shelling workpieces are rigid parts, and workpieces contacting shell grains are rigid hardware, so that when the oil-tea camellia fruits are processed, a plurality of large seeds are extruded and crushed, and small fruits do not achieve the purposes of shelling, shell and seed separation, so that the conditions of high seed and kernel crushing rate and poor shelling effect exist generally.
Disclosure of Invention
In view of the above, the present invention provides a method for hulling camellia fruits to solve the technical problems of low hulling efficiency and poor hulling effect of camellia fruits in the prior art.
The invention solves the technical problems through the following technical scheme:
a method for removing hulls of oil tea fruits comprises the following steps:
s1, steaming, namely putting the picked oil tea fruits into a steam pot, adjusting the steam temperature to 140 ~ 180 ℃, the air pressure to 1 ~ 3Mpa, and steaming for 30 ~ 40 min;
s2, impacting, namely taking out the oil tea fruits autoclaved in the step S1, and sending the oil tea fruits into an impact type cleaning machine for 20 ~ 30 min;
s3, flotation: sending the mixture of the camellia seed and the camellia husk obtained in the step S2 into the suspension for liquid flotation, fishing out the camellia husk floating on the surface of the suspension, and fishing out the camellia seed sinking into the suspension;
s4, drying: and (5) drying the camellia seeds obtained in the step (S3) to obtain the camellia seed food.
In the step S1, the steam temperature is 160 ℃, the air pressure is 2Mpa, and the steam-pressing time is 35 min.
In step S2, the rotational speed of the impact washer is 1000 ~ 2000 r/min.
The suspension was harvested at a density of 1.2 g/cm.
The suspension is brine.
In the step S4, the drying temperature is 100 ~ 120 ℃, and the drying time is 6 ~ 10 h.
The invention has the beneficial effects that: according to the invention, the camellia oleifera fruit is autoclaved, so that the shell of the camellia oleifera fruit is easily separated from the camellia oleifera seeds, then the camellia oleifera seeds are separated from the shell by adopting an impact device, and the camellia oleifera seeds are separated from the shell by flotation, so that the process is simple, the camellia oleifera fruit can be treated in batches, the processing efficiency is high, the hulling rate is high, the hulling effect is good, the oil camellia seed contains less than 0.5% of shell, and the oil camellia seed contains less than 0.6% of seed.
