摘　　要：现代工业化生产炒米存在开花量大、形态不完整、出米率低、炒香味不足等。针对此问题,本研究将电热滚筒烘炒技术应用于炒米加工中,通过单因素实验探究其烘炒炒米的适用性及使用风机条件,确定因素水平;此基础上,进行L 16(43)正交实验,以烘炒效率、感官评价和出米率3个为衡量指标,浸泡时间、蒸煮功率、蒸煮时间和烘炒温度4个为实验因素,得出最佳因素水平组合。实验结果表明:当浸泡时间3 h、蒸煮功率500 W、蒸煮时间40 min、烘炒温度300℃时综合指标达到最佳,其烘炒效率66 g/min,感官指标85分,出米率63.8%。可知,电热滚筒烘炒技术适用于炒米加工,产品的综合指标较高,且设备使用方便、卫生,能少精量加工。The commercial production of parched rice is with advantages,such as plenty of flowering-like rice,uncomplete shape,low yield and insufficient fragrance,etc.In order to address these problems,this article used electrothermal roller technology to process parched rice,by single factor experiment,the applicable of the technology of the roller on backing and the conditions for use of blower would be studied,and the level of factor would be determined.On this basis,L 16(43)orthogonal test was performed on four experimental factors of soaking time,boiling time,boiling power and baking temperature according to three evaluation quotas of baking efficiency,product quality and production rate.The results indicated that the best comprehensive indicators were determined to be 3 hours soaking time,500 W boiling power,40 minutes boiling time and 300℃frying temperature.Under such conditions,the baking efficiency was 66 g/min,the organoleptic indicator was 85 points,and the production rate was 63.8%.Hence,electrothermal roller was applicable to processing of parched rice,the produced products were with high comprehensive indicators,at the same time,the use of the equipment was convenient and healthful,in addition,finishing production with small amount could be achieved.
