米糠制粒浸出工艺的研究与实践Research and practice of rice bran granulation and extraction process
旨在验证改进型糠粞分离器的分离效果和为米糠制粒浸出工艺提供一定的技术参考,采用风选分离糠粞、制粒烘干、平转浸出、负压蒸发、DTDC湿粕脱溶的米糠制粒浸出工艺制取米糠原油，通过总结生产中的一些问题和操作经验,改进了风选式糠粞分离器，确定了颗粒化处理方式及米糠制粒浸出工艺关键点的参数。结果表明：采用改进的糠粞分离器，糠粞分离效果良好，处理量大；以低温制粒烘干代替膨化进行米糠的颗粒化处理，米糠制粒浸出工艺关键点的工艺参数为制粒温度60 ℃，颗粒直径3.7 mm，烘干机出料温度60 ℃，烘干后颗粒水分5%，浸出温度55 ℃，蒸发系统真空度70 kPa，第一蒸发器出油浓度85%、温度65 ℃，第二蒸发器...

| description | 旨在验证改进型糠粞分离器的分离效果和为米糠制粒浸出工艺提供一定的技术参考,采用风选分离糠粞、制粒烘干、平转浸出、负压蒸发、DTDC湿粕脱溶的米糠制粒浸出工艺制取米糠原油，通过总结生产中的一些问题和操作经验,改进了风选式糠粞分离器，确定了颗粒化处理方式及米糠制粒浸出工艺关键点的参数。结果表明：采用改进的糠粞分离器，糠粞分离效果良好，处理量大；以低温制粒烘干代替膨化进行米糠的颗粒化处理，米糠制粒浸出工艺关键点的工艺参数为制粒温度60 ℃，颗粒直径3.7 mm，烘干机出料温度60 ℃，烘干后颗粒水分5%，浸出温度55 ℃，蒸发系统真空度70 kPa，第一蒸发器出油浓度85%、温度65 ℃，第二蒸发器出油浓度95%、温度98 ℃，汽提塔出油温度102 ℃，蒸脱机气相温度76 ℃。采用优化的米糠制粒浸出工艺可改善米糠原油及糠粕品质，并可降低能耗。Aiming to verify the separation effect of improved rice bran and fine broken rice separator and provide certain technical reference for rice bran granulation and extraction process, rice bran granulation and solvent extraction process was used to extract crude rice bran oil,including air separation for rice bran and fine broken rice, granulation drying, rotary leaching, negative pressure evaporation,DTDC wet meal desolventizing. By summarizing some problems and operation experience in production, the rice bran and fine broken rice separator was improved,the granulation treatment was determined, and the key process parameters of rice bran granulation and extraction process were determined.The results showed that rice bran and fine broken rice were separated very well by using the improved rice bran and fine broken rice separator, and the system had a larger capacity. Rice bran particle was prepared using low temperature granulation drying instead of expansion. The key technical parameters of rice bran granulation and solvent extraction process were confirmed as follows: granulation temperature 60 ℃, particle diameter 3.7 mm, discharge temperature of drying machine 60 ℃, particle moisture after drying 5%, solvent extraction temperature 55 ℃, vacuum of evaporation system 70 kPa, oil concentration and temperature of the first evaporator 85% and 65 ℃, oil concentration and temperature of the second evaporator 95% and 98 ℃, oil temperature of stripper 102 ℃, and DTDC vapor phase temperature 76 ℃. The optimized rice bran granulation and solvent extraction process can improve the quality of crude rice bran oil and meal, and reduce energy consumption. |
