Tea tree is native to China, but in one thousand, tea tree is only regarded as leaves with crop, and a considerable number of tea seed, except a handful of seeds used as great part has not been used.According to the Chinese academy of agricultural sciences' institute of tea chun-hua xia et al. Studies show that tea seed oil contains a large number of plants in China, around the content of 23.32, from the composition of tea seed oil, rich in oleic acid and linoleic acid,palm oil processing plant which confirmed tea tree seeds is a rare oil resources.
In our country, the system of industrialization of tea seed oil industry started in the early seventy s, according to the statistics, so far the national t years around the tea seed yield of 3 million bear, and is currently being used only accounted for a quarter.About 80% of tea seed with xj type hydraulic oil mechanism oil process.
A, xj type hydraulic oil press in tea seed, the characteristics and functions of system of oil industry
Xj type hydraulic press is developed in the early 80 s helical mechanical hydraulic oil press, promote fast in recent years, because of its easy installation, structure tight read, spiral reputation system of oil industry.Looked from the process diagram of system of tea seed oil (see chart 1), zx1U type hydraulic oil press machine's main shaft only kernel shell separator, three kinds of crusher and steaming and frying equipment, and the structure is simple, as long as have the manufacturer of mechanical processing capacity, can even their production, therefore, very suitable for the impoverished mountainous area and the development of township tea factory tea seed oil.
Xj type hydraulic press machine mainly consists of feeding device, squeezer, pressing chamber, frame and the gear box of five parts, in the process of pressing tea seed, rely on to squeeze the rotation of the screw thread will be the third steaming Fried tea seed into the clearance volume decreases, the billet by...
