摘　　要：为了开发利用鸡蛋壳和蛋壳膜,首先必须使二者分离。本文采用机械粉碎、水浮选和稀酸处理相结合的方法进行壳膜分离,筛选了鸡蛋壳、壳下膜分离的条件;通过单因素实验考察盐酸体积、反应时间、盐酸浓度对蛋壳膜脱钙率的影响,并采用响应面分析方法,对稀盐酸除蛋壳膜中残留蛋壳的工艺条件进行优化。结果表明:鸡蛋壳在粉碎机运行5 s/次、粉碎3次的条件下壳膜分离效果最佳,出粉率58.72%,脱膜率87.91%,综合得分72.91;用盐酸去除蛋壳膜中残留蛋壳的最佳工艺条件为粗蛋壳膜1 g时,使用盐酸体积20 mL、反应时间19 min、盐酸浓度0.5 mol/L,此时脱钙率可达89.21%。该工艺为鸡蛋壳的精深加工提供技术支撑。The two must be separated first to exploit the eggshell and the eggshell membranes.In this paper,a combination of mechanical crushing,water flotation and dilute acid treatment was used for shell membrane separation,and the conditions of eggshell and subshell membrane separation were screened.The effects of hydrochloric acid volume,reaction time and hydrochloric acid concentration on the rate of eggshell membrane decalcification were investigated by single-factor tests.And the response surface method(RSM)was applied to optimize the process conditions for removing the residual eggshells from the eggshell membranes with dilute hydrochloric acid.The results showed that the shell-membrane separation effect was the best when the eggshells were crushed under the condition that the crusher runs for 5 s/time and crushes 3 times.The powder extraction rate was 58.72%,the membrane removal rate was 87.91%,and the comprehensive score was 72.91.The best conditions for removing the residual eggshell in the eggshell membrane with hydrochloric acid were 1 g crude eggshell membrane,20 mL hydrochloric acid,19 min reaction time,and 0.5 mol/L hydrochloric acid concentration,and the decalcification rate could reach 89.21%.This process would provide the technical support for the intensive processing of the eggshell.
