补充资料：RGTGN套管杀菌机系列浓浆型
应用：
应用于浓缩果浆、果酱(如番茄酱、杏酱)等流体食品，物料在套管式热交换器中进行高温杀菌处理。
工作原理：
杀菌机是通过在高压下用循环热水30分钟来实现灭菌的，除菌后，系统逐步被降至生产温度，就可以进入生产阶段。
产品在经过前期处理后，进入杀菌机物料罐，输送泵将产品送入套管热交换单元进行预热。
最后在管式热交换器中进行加热，产品须在保温管中保温一定的要求时间以取得预定的杀菌效果。
产品在波纹管中利用热回收方式冷却至包装温度。
每个生产周期结束后，都要用碱液或酸对系统进行清洗。
设备组成及技术指标：
由物桶、套管式换热器、无级变速输送泵、高压柱塞泵、保持器、密闭水桶、热水发生器、控制柜等组成。
采用镜面焊接技术，保持管道连接平滑，减少物料残留。
采用波纹管连接，减少热变形应力。
杀菌不足自动返回管路，确保系统无菌性。
无菌阀，冷却管路连接法蓝采用蒸汽保护。
采用热回收技术，提高热传输效率，节约能源。
液位，温度实时控制。
