(a) the production process: camellia oil
1, press legal oil process
(1) tea seed kernel system of cold pressed oil technology
Tea seed to clean up in removing impurity, shell and the shell kernel separation - cold pressed - cold pressed oil - coarse filter - MAO qing filter to high quality cold oil, high quality tea seed cake
Cold pressed tea seed oil production has simple process, oil is of good quality and save energy, low operation cost and less equipment investment, cover an area of an area small, etc.
(2) the tea seed kernel oil high temperature crushing system technology
Tea seed to clean up in removing impurity, shell and shell kernel separation to tea benevolence, steaming Fried to squeeze out the oil to precipitation, filtration, tea oil, (3) oil system of supercritical fluid extraction technology
Tea seed to clean up in removing impurity, shell and shell kernel separation - tea kernel separation - CO2 extraction and separation of 1-2 - rectification - tea oil
2, leaching rule of oil process
(1) the camellia oil leaching oil equipment mainly includes:
Feeding scraper conveyor, storage container, material sealing ground dragon, swing type leacher oil immersion system equipment; Wet meal conveyor, closed ground dragon, take off the solvent machine material such as meal desolventizing equipment system; Temporary cans, mixed oil mixtures, such as the first and second evaporator, stripper oil evaporation separation equipment system; Condenser, water tanks, tank, and turnover of tail gas absorber, solvent tank, solvent recovery equipment system;
(2) of the refining technology of camellia oil
1, chemical refining technology of tea oil
Raw material oil - to take off the rubber - acid to water wash to take off color, deodorization, winterization skim - > finished camellia oil
2, physical refining technology of tea oil
Raw oil and filter to remove waste rubber to off color, acid, camellia oil
(3) the camellia oil winterization degreasing process and equipment
(1) in the winter of the production process
Tea oil to heat exchanger to the crystallizer, heating tank, oil filters - > winter
(2) the winter working principle:
To low temperature crystallization winterization system mainly for the oil in the wax separated out
(3) winterization processing range:
(4) main for winterization processing of oil sunflower oil, cottonseed oil and grape seed oil, etc
(5) the winter can be divided into wet and dry type two kinds:
A. wet winterization
Principle for cooking oil after bleaching stage, soapstock particles as seed, rapid crystallization, separate the wax crystallization by washing with water, but because of the rapid crystallization is still part of wax residue, therefore, to reach the standard of 5.5 hours after crystallization 0 ℃ still no wax crystallization precipitation, if you need less caused by low temperature conditions of atomization, can add another slow after deodorization crystal will trace of wax and sugar to fine filtering to remove.
Advantages to reduce the use of filtering agent, such as cost of lignocellulose and diatomite, the operation can reduce the filter in the frequency of slot.
B. dry winter,
After principle for decolorization and deodorization, oil cooling, with slow crystallization, making wax crystallization can cultivate large crystal, and the use of filter additives such as lignocellulose and diatomite to remove large and small particles of wax crystallization, in order to achieve almost entirely remove the oil in the wax.
Advantages for 12 hr, according to the requirements of oil winterization of 0 ℃ or 24 hr, 0 ℃ not atomization conditions, can be controlled by the crystallization time and filter conditions
(6) winterization equipment:
Crystal filter, the cans, crystallizing tank, refrigerating machine, mixer, industrial boilers, etc
