摘　　要：对大豆油无水脱皂技术进行了研究,考察了吸附剂、过滤温度、滤饼厚度、脱胶脱酸油中含皂量、含磷量对无水脱皂后清油中残皂量和残磷量的影响。结果表明,采用硅藻土对脱胶脱酸油吸附脱皂效果比废白土稍好,但成本较高;脱胶脱酸油中含皂量在260 mg/kg以下、含磷量在14 mg/kg以下时,采用废白土无水脱皂效果较好;65℃过滤脱皂脱磷效果较好;滤饼厚度增加有利于脱皂脱磷,但滤饼过厚会导致过滤机压力快速增加不利于实际生产。The soap removal from soybean oil without water washing was studied. The effects of adsorbent, filter temperature, filter cake thickness and content of soap and phosphorus in degummed and deacidified soybean oil on the content of residual soap and phosphorus in the pure soybean oil were researched. The results showed that the effect of diatomite on soap removal from degummed and deacidified soybean oil was better than waste clay, while the cost of diatomite was higher. When the contents of soap and phosphorus in degummed and deacidified soybean oil were below 260 mg/kg and 14 mg/kg respectively, the effect of waste clay on soap removal without water washing was great. The effects of soap and phosphorus removal at 65 ℃ were better. of soap and phosphorus which went against the Improving the filter cake thickness , while filter cake being too thick would increase the actual production. was beneficial to the removal pressure of the filter rapidly,
