通常建造灭菌灶，铁锅口直径与蒸仓体积比为１：２．５，即直径为１ｍ的铁锅，蒸合体积为２．５ｍ３。为了使灶体灭菌仓体积更大，有的菇农片面扩大灶体积，而铁锅相对蒸发面积小，不能产生足够的热量，温度难以升至１００℃，且水位难测定，易烧于锅，灭菌不理想。为此，笔者 Usually build a sterilization stove, iron pot mouth diameter and steaming warehouse volume ratio of 1: 2.5, that is, a diameter of 1m wok, steaming volume of 2.5m3. In order to make the sterilizing chamber body volume larger, and some mushroom noodles to expand the size of stove, while the relative evaporation area of ​​the wok is small, can not produce enough heat, the temperature is difficult to rise to 100 ℃, and the water level is difficult to determine, easy to burn pot , Sterilization is not ideal. To this end, the author
