摘　　要：为解决酱油厂黄梅季节染菌问题,研制了一种小型固态发酵反应器。该反应器以强制空气对流为主要散热方式,并且加入了搅拌和喷水装置。通过酱油种曲制备实验,确定了反应器的温度反馈点和控制点。根据进出口气体的温度及湿度,计算床层水分蒸发量。以吸收装置测定反应器尾气中二氧化碳含量,建立了反映反应器中菌体代谢状况的方法。实验表明该反应器能达到种曲制备的要求。In order to prevent the spore starter for soy sauce fermentation from contamination under humectate weather, a small solid - state fermentot for preparing spore starter was developed. Besides forced aeration as a major cooling method, stirring and sprinkling structures were added to enforce efficiency of heat transfer in the bed. Based on experiment data, detection point and control point of the temperature were determined. The evaporated water was calculated via the temperature and humidity at inlet and outlet air. Carbon dioxide in the tail gas was measured by an absorbent unit attached on the reactor. A method illustrating cell metabolic state was established according to temperature change and released Carbon dioxide. The reactor can well meet the need for preparing spore starter for soy sauce production.
