The penguin experts explain the polycoagulant dewaxing technology and urea dewaxing process
凝聚剂脱蜡技术流程图
Polycoagulant dewaxing technology flowchart
以凝聚剂法脱蜡时，先将含蜡油冷至9-13℃，然后拌和，增加理论碱量中和游离脂肪酸所用浓度为15°Be`分配，拌和(60-70r/min)1-1.2hr后，增加占油量0.1%的硫酸铝(配成浓度为13.6-30%的水溶液)，持续拌和1-1.2hr，终温不得跨越17℃，然后经别离、洗刷及单调，即得脱蜡油。
To coagulant dewaxing process, the first containing wax cold to 9-13 DEG C, and then mixing, increase theory of alkali and free fatty acid concentration is 15 degrees Be` distribution, mixing and 60-70r/min 1-1.2hr increased representing 13.6-30% aqueous solution), continuous mixing 1-1.2hr, eventually temperature shall not be spanned 17 DEG C, and then after separation, washing and monotone, that was dewaxed oil of oil amount of 0.1% aluminum sulfate (with concentration.
尿素脱蜡法
Urea dewaxing process
本法是经过增加尿素溶液包合蜡分子共结晶的一种脱蜡办法。
This method is a way to increase the inclusion of urea dewaxing wax molecules Co crystallization.
首先将含蜡油按惯例办法碱炼，然后冷至10℃分配，增加油量3%的尿素(配成丰满水溶液)拌和、结晶20-24hr，经离心别离、水洗、单调即得脱蜡成品油、尿素脱蜡法与惯例脱蜡法(即单纯机械别离法)设备通用，脱蜡率较高，残留尿素可联系后续工序脱除;
First containing wax according to conventional methods of alkali refining, then cooled to 10 DEG C allocation, increase 3% oil content of urea (with full water solution) mixing, crystallization 20-24hr. After centrifugal separation, washing, monotonous the dewaxing the refined oil, urea dewaxing method and practice dewaxing method (namely pure mechanical don't off) general equipment, dewaxing rate is higher, residual urea can contact follow-up procedure to remove;
但尿素的分化商品氨会构成环境污染，该办法有待技术和设备的进一步完善。
However, the differentiation of urea can constitute the environmental pollution, the way to further improve the technology and equipment.
本发明供给一种食用油脂脱胶办法，该办法包含以下进程：将刚榨出的毛油加热到90℃-110℃;
The present invention provides a kind of edible oil degumming methods, the way to contain the following process: just squeeze the crude oil heating to 90 and 110 DEG C;
在上述加热后的毛油中参与硅藻土，充沛拌和、混合，再进行过滤，得过滤油;对所述过滤油进行电别离处理，得到带有絮状物的油;
In heating the crude oil in diatomite, fully mixing, mixing, filtering, filter oil; on the filter oil were electric separation processing, with floc oil;
对带有絮状物的油进行离心处理，去掉絮状物，得脱胶油;根据上述，所述硅藻土的参与量是毛油重量的0.5%-1.5%。
On with floc oil centrifugal processing, remove the floc, oil degumming; according to the above, the amount involved in the diatomite is 0.5% - 1.5% of the gross weight of the oil.
该办法能够去掉胶体，使油脂中的含磷量降至12ppm，并可代替传统的水化脱胶和酸炼脱胶，节省耗费20%，前进生关速度，下出生关本钱40%，一起，减少精粹废水15%，维护生态环境，其技术流程简练，出产本钱低，脱胶作用好，可前进油品质量。
The approach can remove colloid, fell to 12 ppm of phosphorus content in the oil, and can replace the traditional water degumming and acid degumming, save cost 20%, advance student off speed, born off 40% of the cost, together, to reduce the essence of 15% of the wastewater, the maintenance of the ecological environment, the technical processes simple practice, low production cost, good degumming effect, advance the quality of oil.
