30M^3标准型通风发酵罐进行液态深层米醋发酵的应用研究

本文报道了以30M^3标准型风发酵罐配合ND三级空气过滤装置为主体发酵设备进行液态深层发酵制醋的研究，分析了该罐较之自吸式发酵罐在保持纯种发酵、发酵条件和节能等方面所具有的优势。研究证实：在此罐中采用半连续侵害工艺制醋，平均产酸达6.31％，酒精转酸率98.1%，生酸速度0.124%／h，主料出醋水平达12.20kg醋/kg米（折合含醋酸3.5％成品汁），并可保证长期纯种发酵。

Study on 30M3 standard form air blow fermentor for deep layer fermented vinegar

In this paper,the application of 30M 3 standard form air blow fermentor with ND three grades air cleaning as the main equipment for deep layer fermented vinegar is reported.Compared with self-priming fermentor,the former has some advantages on pure culture maintenance,better ferment conditions and energy saving.The result proves:with semi-conti-nuous fermentation for vinegar producing,the average HAC is 6 31%,the rate of alcohol utilization reaches to 98.1%,the rate of HAC growth is 0.124%/h,and the efficiency is 12.20 kg vinegar/kg rice(3.5% HAC).This equipment could guarantee long-time pure strain fermentation.
