Abstract

本实用新型涉及机械技术领域，具体地说是一种乳酸菌发酵生产用的气升式发酵罐。一种乳酸菌发酵生产用的气升式发酵罐，包括发酵罐、空气喷嘴、气升桶、导流桶、二次补气环管，其特征在于：发酵罐的底部中央设有空气喷嘴，并且空气喷嘴的上端穿入发酵罐内，空气喷嘴的正上方位于发酵罐的内部设有气升桶，气升桶的外侧设有导流桶，导流桶的外侧上方设有二次补气环管。同现有技术相比，设计出专门针对厌氧型乳酸菌发酵的发酵罐，使二氧化碳气体从罐底部通入发酵液，保证混合均匀，同时二氧化碳气体有利于乳酸菌厌氧发酵，避免传统利用搅拌的原理对乳酸菌造成伤害，提高生产效率。

Description

一种乳酸菌发酵生产用的气升式发酵罐
技术领域
本实用新型涉及机械技术领域，具体地说是一种乳酸菌发酵生产用的气升式发酵罐。
背景技术
常规的乳酸菌发酵罐是利用搅拌的原理对乳酸菌进行发酵，但是对于厌氧的乳酸菌发酵，搅拌的原理对其发酵起不到任何作用，反而对乳酸菌的发酵生产不利，影响生产质量。 
发明内容
本实用新型为克服现有技术的不足，改造出一种气升式的发酵罐，专门针对厌氧型乳酸菌的发酵，使其发酵均匀，提高生产效率。
为实现上述目的，设计一种乳酸菌发酵生产用的气升式发酵罐，包括发酵罐、空气喷嘴、气升桶、导流桶、二次补气环管，其特征在于：发酵罐的底部中央设有空气喷嘴，并且空气喷嘴的上端穿入发酵罐内，空气喷嘴的正上方位于发酵罐的内部设有气升桶，气升桶的外侧设有导流桶，导流桶的外侧上方设有二次补气环管。
本实用新型同现有技术相比，设计出专门针对厌氧型乳酸菌发酵的发酵罐，使二氧化碳气体从罐底部通入发酵液，保证混合均匀，同时二氧化碳气体有利于乳酸菌厌氧发酵，避免传统利用搅拌的原理对乳酸菌造成伤害，提高生产效率。
附图说明
图1为本实用新型结构示意图。
参见图1，1为空气喷嘴，2为气升桶，3为导流桶，4为发酵罐，5为二次补气环管。
具体实施方式
下面根据附图对本实用新型做进一步的说明。
如图1所示，发酵罐4的底部中央设有空气喷嘴1，并且空气喷嘴1的上端穿入发酵罐4内，空气喷嘴1的正上方位于发酵罐4的内部设有气升桶2，气升桶2的外侧设有导流桶3，导流桶3的外侧上方设有二次补气环管5。
工作时，将二氧化碳气体直接从发酵罐4的罐底通入至发酵液，保证混合均匀，当二氧化碳气体不够时，导流桶3的外侧上方的二次补气环管5进行补气，使发酵液中二氧化碳量足够乳酸菌厌氧发酵，避免了传统利用搅拌的原理对乳酸菌造成伤害，提高生产效率。
