Tea oil is one of edible oils. It is rich in nutrients and is a fine product in edible oil. It has high economic value. With the improvement of people's living standards, tea oil is popular among people in daily life. Let's share the good tea oil production technology and equipment for producing tea oil!
Edible oil made from wild camellia. Also known as camellia seed oil, camellia oil. Camellia oleifera grows in a subtropical Nanling humid climate zone without pollution. No pesticides or fertilizers are applied throughout the growth process. Contains no erucic acid, cholesterol, aflatoxin and other harmful substances. The color is golden or light yellow, the quality is pure, clear and clear, the smell is fragrant, and the taste is pure. So how do you make tea oil? What are the production skills and equipment of tea oil? The following small series will introduce you to the common sense, let's take a look!
How to make tea oil? Tea oil production skills and equipment
One: harvesting
There are many types of Camellia oleifera, and the fruit ripening period is generally from the beginning of October to November. The experienced fruit has the following characteristics: the color of the tea fruit is bright, red or yellow, oily, the feathers of the peel are exhausted, and the fruit base is hard and thick, and the shell is Micro-cracking, the seed shell becomes black and bright, and the seed kernel is oily. Tea fruit should be harvested in time. Different types of tea fruit should be harvested first, then harvested, and then harvested; the same type of sophisticated tea should also be harvested in the next 7 days. The tea fruit collected should be placed indoors for 6-7 days, so that the tea seeds can be cooked and added with oil. Then grasp the sunny day, spread the sun, after 3-4 days of drying, the tea fruit is naturally cracked, most of the fruit of the tea can be separated, not separated from the artificial peeling, and then sifted, dry, usually drying for 12 days In order to fully convert organic substances such as starch and soluble sugar into fats and oils. The use of soil slabs or bamboo mats for tea seeding is better than cement slabs, which can improve the oil yield and quality of tea oil. In case of rainy days, it is not possible to dry in time. The tea seeds should be laid on a dry and ventilated floor, about 20 cm thick, and turned 1-2 times a day to prevent fever and mildew or germination. After the oil tea seed is dried and the ratio of the shell is 1:2, the dried tea seed should be placed in a ventilated and dry place. After the 1-2 months, the oil content of the tea seed reaches the highest, and the aging is 1-2 days. This way, the oil yield is high and the oil quality is good.
Two: oil extraction
Extracting tea oil from tea seeds is now basically a press method. The traditional oil pressing in rural China is a wood press, which has high labor intensity and low oil yield. It will gradually be replaced by hydraulic presses and screw machines.
It needs to be destroyed and steamed before pressing:
1 Destruction: The Camellia oleifera seed is shelled. In order to prevent the difficulty of shelling and the excessive breakage of the seed kernel, it is necessary to control the moisture content of the tea seed within 5%-6%. After shelling, it is processed into powder by the destruction machine. If stone milling is used, it is necessary to sift several times during the rolling process in order to roll finely and without coarse particles, and obtain a higher oil yield.
2 Steaming and frying: The purpose of steaming and frying is to make the raw material old and mature, to make the color of the blank deeper, and it is in the most suitable state for oil outflow, which is a key process before pressing. The traditional steamed stir fry is steamed with hibiscus and fried in an iron pan. Raw materials are first steamed or sprayed with water and then fried, called "wet steamed"; fried without frying, called "dry steamed", generally "wet steamed" as well. The moisture and temperature during steaming vary depending on the type of machine used. With hydraulic press and wood press, the temperature of the stir-fry is generally 110-120 ° C, and the water content after steaming is 7%-8%. The temperature of the fried material is generally 130-140 ° C with a screw press, and the water content after steaming is 3% - 4%.
Tea oil production skills and equipment
   1. Dry the tea grains
2. Use a screw machine to tumbling to 7.8%
3. Then use the screw press to squeeze the tea seed oil
4. Merit
(1) Preparation process of camellia oil:
1. Leaching process oil production process
(1) The complete set of equipment for extracting and extracting camellia oil mainly includes: feeding scraper conveyor, storage box, material sealing auger, flat-type leaching device and other oil immersion system equipment; wet conveyor, closing auger, off Solvent machine and other materials 粕 desolvation equipment system; mixed oil temporary storage tank, one, two transpiration, stripper and other mixed oil transpiration separate equipment system; condenser group, water tank, balance tank, exhaust gas absorber, solvent turnover tank And other solvent recovery equipment systems;
2. Pressing process oil production process
(1) Tea seed kernel cold-pressing oil skill
Camellia seed → finishing and removing impurities → shelling and shell separation → cold pressing → cold pressed oil → coarse filtration → clear filtration → high quality cold pressed oil → high quality tea seed cake
The oil-tea seed oil cold-pressing oil production process has the advantages of simple process, good quality of oil, energy saving, low running cost, low equipment investment, and small floor space.
(2) Tea seed kernel high temperature pressing oil production skills
Camellia oleifera → finishing and removing impurities → shelling and shell kernels → tea kernels → steaming and frying → pressing oil → sedimentation → filtration → tea oil
(3) Supercritical extraction oil production skills
Camellia seed → sorting and removing → shelling and shell kernel separation → tea kernel → CO2 extraction → leave 1 → separate 2 → rectification → tea oil
(2) The essence of camellia oil
1. The chemical essence of tea oil
Material oil → degumming → deacidification → water washing → bleaching → deodorization → winter degreasing → product camellia oil
2. The physical essence of tea oil
Material oil → filtration → degumming → decolorization → deacidification → product camellia oil
(3) Winter degreasing process and equipment of camellia oil
(1) Winter production process
Tea oil→heat exchanger→crystallization tank→heating tank→filter→winter oil
(2) Principle of winterization operation:
The winterization system mainly separates the wax from the oil by low-temperature crystallization.
(3) Winter treatment scale:
(4) The oils for winter treatment are mainly sunflower oil, cottonseed oil and grape seed oil, etc.
(5) Winterization can be divided into wet and dry
(1) Wet winterization
The principle is that after the edible oil passes through the decolorization stage, the soapy granules are seeded, and after rapid crystallization, the wax crystals are separated by water washing, but some of the wax remains after rapid crystallization, so the specification after crystallization is 5.5. At 0 ° C, there is still no wax crystals. If less conditions for low temperature atomization are required, another slow crystal may be added after deodorization to remove trace amounts of wax and sugar by precision filtration. The strength is to reduce the cost of using filter auxiliaries, such as lignocellulose and diatomaceous earth, and to reduce the frequency of the filter change.
(2) Dry winterization
After the principle is decolorization or deodorization, the edible oil is cooled, and the crystal is slowly crystallized, so that the wax crystal can be cultivated into a large crystal, and the wax of the large and small particles is removed by using a filter aid such as lignocellulose and diatomaceous earth. In order to arrive, it is completely removed from the wax in the oil. The strength is that according to the requirements of winter chemical oil, it reaches 12HR, 0°C or 24HR, and the condition of 0°C will not be atomized. It can be controlled by crystallization time and filtration conditions.
(3) Winterization equipment
Filters, crystal tanks, crystallization tanks, refrigerators, mixers, industrial boilers, etc.
In the view of Hui Nong.com, the reason why tea oil is precious is that it is a green and natural healthy edible vegetable oil, and the second is that its production process is complicated by the hard oil products. The third is that the nutritional value is high. The best in oil, the above is the introduction of tea oil production technology and equipment, I hope to help farmers!
