Problems solved by technology

[0003] At present, the production methods of Camellia oleifera seed oil in my country mainly include mechanical pressing and hot pressing and solvent extraction. The pressing method has many equipments and high oil residue rate, and the traditional high-temperature hot pressing of tea oil is easy to damage active substances such as vitamins.
The leaching method uses 6# solvent, although it has the advantages of low cost and high oil yield, but the organic solvent has potential safety hazards, and the released solvent gas is not friendly to the environment

Embodiment Construction

[0017] A kind of cold pressing process of camellia oleifera seed, comprises the following steps:

[0018] 1) Select Camellia oleifera seeds, remove impurities, and obtain pure Camellia oleifera seeds;

[0019] 2) Drying, using a vertical drying tower, the heat source is a hot air stove fueled by organic energy to supply hot air, the temperature of the hot air is controlled at 55°C-65°C, and the moisture content of the dried camellia seeds is controlled at 7.5%-9%;

[0020] 3) Dehulling: dehulling the Camellia oleifera seeds obtained in step (2) to obtain Camellia oleifera kernels with a certain shell content;

[0021] 4) Drying and crushing: put the camellia seed obtained in step (3) into an oven at 60°C for drying, bake the camellia seed until the moisture content is less than 8%, take it out and crush it, and use a roller crusher to crush the camellia seed , control the crushing degree to 1 / 4 ~ 1 / 8 petals of Camellia oleifera seeds;

[0022] 5) Low-te...

Abstract

The invention relates to an oil tea seed cold pressing technique which comprises the following steps: selecting oil tea seed, drying, shelling, drying, crushing, carrying out cold pressing, filtering, hydrating, degumming, carrying out medium temperature drying, refrigerating to crystallize, and filling. The product quality is controlled from the raw material acquisition and raw material storage time, and the fresh seed fresh pressing and low-temperature low-pressure conditions are creatively used in the process, thereby ensuring the control on the raw oil acid number and no loss of nutrients to some extent, and enhancing the raw oil quality and the utilization value of the tea cake for byproduct deep processing. The refrigeration crystallization and activated carbon adsorption are utilized to remove the harmful substances in the oil, and the inherent characteristics and nutrients in the oil tea seed oil are effectively maintained, thereby greatly improving the oil quality. The inert gas charging process is adopted to enhance the preservation period and stability of the oil and avoid using additives, thereby ensuring to use the physical production method in the overall process.

Description

technical field [0001] The invention relates to a cold pressing process of camellia oleifera seeds. Background technique [0002] Camellia oleifera originated in China. It is the main woody edible oil tree species unique to southern my country and one of the four largest woody edible oil tree species in the world. The area of ​​Camellia oleifera forests in my country accounts for more than 80% of the woody edible oil plant area. The oil obtained from Camellia oleifera seeds is Camellia oil, the fatty acid composition of Camellia oil is similar to high-grade edible oil - olive oil, its unsaturated fatty acid content exceeds 80%, has high nutritional value; No chemical fertilizers and pesticides are applied during the cultivation of Camellia oleifera , so camellia oil belongs to natural green food. A variety of functional components in camellia oil have obvious effects on maintaining the function of the cardiovascular system, improving human immunity, lowering cholester...
