Teaseeds Oil Production Process

Camellia oil production

Extracting camellia oil from tea seeds is a traditional extraction process. Pressing is also a basic way to extract tea oil.
After pressing the tea seeds to obtain "pressed raw tea oil", the oil in the tea cake is fully extracted by leaching to obtain "leached raw tea oil".

Camellia oil pressing process

Oil tea seeds→drying→cleaning→shelling→shell-kernel separation→rolling→steaming→pressing→impurity shell tea cake→filtration→crude oil.
1 Drying: This process is to prepare for shelling. The moisture content of the dried tea seeds reaches 12%~14%.
2 Cleaning: Sieve and clean to remove sand, mud, stems, leaves, ironware and other debris in the tea seeds.
3 Shelling: The dried tea seeds are sent to the tea seed shelling machine for shelling. In addition, from the perspective of improving the quality of tea saponin, the shelling process of tea seeds plays a decisive role in improving the color of tea saponin.
4 Shell-kernel separation: After the shell is broken, the oil tea seeds are immediately sorted by wind to separate the kernel from the shell.
5 Flaking: Since the shelled tea kernels have a high oil content and cannot be crushed by a crusher, they must be pressed into sheets by a large gap, low-speed flaking machine.
6 Steaming and frying: The moisture and temperature of the tea kernels are adjusted in the steaming and frying pan to ensure that the moisture content before pressing is about 3% and the pressing temperature reaches 110~120℃.
7 Pressing: In addition to the traditional pressing method, there are two main types of oil extraction: hydraulic press oil pressing and screw press oil pressing.
The complete set of camellia oil extraction equipment mainly includes:
Feeding scraper conveyor, storage box, material sealing auger, horizontal rotary extractor and other oil soaking system equipment; wet meal conveyor, closed auger, desolventizer and other meal desolventizing equipment system; mixed oil temporary storage tank, first and second evaporators, stripper and other mixed oil evaporation separation equipment system; condenser group, water distribution tank, balance tank, tail gas absorber, solvent turnover tank and other solvent recovery equipment system;
Crude tea oil filtration
The crude oil obtained after pressing contains many impurities, which affect the quality, stability and taste of the oil and need to be removed. The use of filtration equipment can remove insoluble mechanical impurities in the crude oil. Other impurities contained in the crude oil, such as colloid-soluble impurities, free fatty acids, pigments and odors, need to be removed through refining (degumming, deacidification, decolorization, deodorization).

Camellia oil refining process

1. Chemical refining process of camellia oil
Raw material crude oil → degumming → deacidification → water washing → decolorization → deodorization → winterization and defatting → finished camellia oil
2. Physical refining process of camellia oil
Raw material crude oil → filtration → degumming → decolorization → deacidification → finished camellia oil
