| Camellia oleifera Abel is the main woody edible oil tree in China. Total area of national Camellia oleifera Abel is about 55 million mu, which accounts for 80% of our woody edible oil area. National annual output of camellia oil is about 150-200 thousand ton, which accounts for 80% of our woody edible oil output. Camellia oleifera Abel is the scarce resource in the world. The quality and value of camellia oil were the same as olive oil. And the clinical outcome shows that camellia oil can effectively prevent and treat cardiovascular and cerebrovascular diseases, decrease cholesterol and fasting plasma glucose, inhibit the increase of triacylglycerol and help patients with hypertension, hyperproteinemia and hyperglycemia to improve their health. Camellia oil is storagable, not rancid easily and against pollution of carcinogenic Aflatoxin B1. At the same time, camellia oil is also an important high-quality raw material in food, pharmaceutical, chemical and cosmetic industries.At present, the method of camellia oil-making is mainly squeezing and extracting. The method of squeezing and frying in high temperature has many negative effects such as equipment too much; technological operation too complex; crude oil dark color and too much solvent of 6# consumption, which produce many safety problems and destroy our environment. Moreover, during the process of separating crude oil, high temperature destroys the natural vitamin and other nutrients. Also the cost is high. The way of fining about camellia oil is intermittent, which can result in the breakage of Vitamin due to heater of stove. What's more, mineral oil used in process of heating stove will produce carcinogen. Then during the technique of deodorization, trans fatty acids will be engendered because of high vacuum, which affects the quality of camellia oil. In conclusion, predicaments existed in current camellia oil processing industry, which are many enterprises with small scale, low level of technique, much operation, high cost and polluting environment. Trans fatty acids in the whole process depress the quality of product. So there is pressing need of new technique that can promote development of camellia oil business.In this paper, a new camellia oil processing factory with an annual capacity of 15000t refined camellia oil was planned to establish in Yichun city which is the important Camellia oleifera Abel region from this paper. On the selection of technological line, this study analyzed and compared current processing technology of camellia oil, and used advanced technological line at home and abroad for the construction of new project. The new camellia oil processing factory used advanced cold pressing technology about below 50 degree in which remnant oil are low and the quality of crude oil can achieve the standard of GB11765-2003. Moreover, there are other techniques such as box chain leaching, negative pressure evaporation technology whose effect is good including low remnant oil, fair crude oil, small quantity of consumption about solvent, less effect on environment. Soft column deodorization technology conformed to EU technical standards whose degree of automatization is high. Its batch variance is little and the degree of safety is high. Vitamin E is kept in the oil about more than 85% and trans fatty acids are lower than 1% up to EU technical standards. The consumption of energy and cost are low. These are their main technical route.Location Selection, product scheme, technological process, equipment selection, balance of water, electric and gas, workshop horizontal design, architectural requirement and environmental requirement were studied for the project construction. Establishing a processing enterprise with scalization, modernization and a dvanced technology at home and abroad is to provide technical demonstration for camellia oil processing industry. Raising the whole level of camellia oil processing industry is to provide a technology support for rapid development of camellia oil industry. |
