The mountain village is rich in tea seed, many tea seed on-site processing, tea seed oil is mainly adopts the method of alkali refining, can take off acid, to impurities, and can go to a part of the pigment and smell, as to meet the requirement of cooking oil.Tea seed oil refining process is the main equipment crude oil store, alkali neutralization, water tank, filter, and a separation of soapstock and pump,palm oil refinery plant alkali pool, etc.
(1) coarse alkali refining process of tea seed oil
Coarse tea seed oil - alkaline neutralization - temperature - static sedimentation - net oil - water - dry filter -- -- -- -- -- -- - packing refined tea seed oil storage
(2) the technology of camellia seed oil refining equipment operating points
(1) after the oil pump into the neutralization tank metering MAO, then stir well, acid value, sample and calculate the amount of alkaline, to calculate the super alkaline.
(2) adjust the oil temperature at the beginning of about 30 ℃.Under the summer temperature is the oil temperature, alkali appropriate heating in winter.draught fan
(3) alkaline neutralization lye concentration for 12-18 ° Be commonly. The actual join alkali concentrations of less than 10 acid value of 12-14 ° Be, more than 10 acid value of 16-18 ° Be.Under the alkaline in the cross pipe, tube from three directions into 40 ° Angle, staggered three rows of holes, the aperture is 3 mm, spray requirements after about 20 min and lye.Fast mixing, stirring speed of 60-70 r/min.
(4) temperature alkaline stir after 15 min, make oil and alkali mix, alkali and oil free fatty acids in the preliminary, and then began to heat up, the rate of warming per minute increased 1 ℃ advisable.Up to 50 ℃ when separate began to observe oil soap, if oil soap obvious separation, soap from fine to coarse grain, namely stops heating up.Warming up to 50 ℃, the slow speed of 30-40 r/min. 10 people arrived at the final temperature continue to stir.Observe the separation of oil soap,...
