连续灭菌,即培养基的连续灭菌,也叫连消。是灭菌的一种方式。就是将配制好的并经预热(60~75℃)的培养基用泵连续输入由直接蒸汽加热的加热塔,使其在短时间内达到灭菌温度(126~132℃)。然后进入维持罐(或维持管),使在灭菌温度下维持5~7分钟后再进入冷却管,使其冷却至接种温度并直接进入已事先灭菌(空罐灭菌)过的发酵罐内。其过程均包括加热、维持和冷却等灭菌操作过程。培养基的冷却方式有喷淋冷却式、真空冷却式、薄板换热器式几种方式。
当前有两种简化的原则,可用于食品连续灭菌的设计。
Two simplified design hales have been used for the design and operation of continuous sterilisation process of food fluid.
结论MKJ除菌消毒空气洁净器高效、省时、简便、安全性高,尤其能在有人活动场合连续灭菌消毒。

对近年来食品连续灭菌过程的研究进展进行了综述,指出了在某些情况下采用高温短时灭菌(HTST)可能导致明显的加工过头而造成食品质量下降或风味改变。
In some situations using high temperature short-time sterilisation(HTST) may cause the obvious excessive pyrogenation, therefore resulting in a reduction in food quality or change on food flavor.
