糙米加湿调质均质时间的研究

Study on the Optimum Rice Homogenizing Time after Conditioning

以含水量12.5%的糙米为原料,将糙米加湿调质到不同含水量,并取不同均质时间糙米样品做磨米加工试验,检测精米率、碎米和精裂纹米率、功耗。研究证实,糙米加湿后完全均质时间在400min以后,且可以避免加湿过程中产生的应力裂纹,而且可以降低磨米能耗、增加出米率、提高大米品质。

This article takes the water content 12.5% brown rice as a raw-material. Use moisture contents for rice milling and study the experimental raw-material after the brown rice are grinded..Tested the energy consumption and the rate of broken rice and rate of cracking rice during grinded. It can be confirmed that the thorough homogenizing time after conditioning is more than 400 minutes and the cracking rice produced by amount of water adding to the brown rice are avoided, the energy consumption is reduced and rice milling yield is raised and quality of rice is enhanced.
