The utility model discloses a heat preservation type water natto fermentation machine, which comprises a shell, the shell is arranged at the top of the lid, the shell is internally provided with a liner, the liner is arranged in a plurality of U tube, the top of the U tube is open, and extends to the top of the cover, the U tube a plurality of vent holes, the side wall of the housing near the bottom is provided with a water inlet interface, near the top of the side wall of the casing is provided with a water outlet interface, a gap is reserved between the housing and the liner, from the water inlet water toward the gap, the water discharged from the water outlet interface, water flow formed in the gap. The utility model generates heat during the fermentation of natto, and the heat diffuses from the ventilating hole to the U shaped tube. One end of the U shaped tube enters the air and the other ends discharge the air. When the air passes through the U shaped tube, the heat is taken out to provide air for the natto and play the role of supplying oxygen. Ensure the conditions of fermentation, and do not damage the natto, so as to ensure the integrity of the grains of the natto.

水保温式纳豆发酵机
本技术涉及水保温式纳豆发酵机,属于纳豆发酵
技术介绍
纳豆的生产工艺:(1)原料的处理──筛选合格的原料大豆;(2)洗豆、浸渍;(3)蒸煮;(4)接种纳豆菌;(5)装放充填到容器内;(6)发酵。纳豆生产中关键的工序是发酵,在发酵过程中纳豆菌繁殖到达对数期时会产生大量的发酵热,平均大约经8小时就产生大量热,原料大豆温度即开始上升,到12小时其温度会突破50℃,表面积较大的极小粒大豆或磨碎大豆等较快表现温度的上升。在此阶段因氧气需要量大,用给气,排气装置,一面提供空气,一面排出发酵代谢气体及水气。发酵过程需要特别控制的因素就是:第一:通风补氧,第二:恒温,第三:湿度。现有的发酵罐通过搅拌的方式来实现纳豆发酵过程的供氧,搅拌不仅会破坏纳豆,将纳豆搅拌碎裂,同时,把发酵菌的生活环境破坏,不利于发酵菌发酵,造成发酵效果不理想,纳豆颗粒不完整。
