管式灭菌机

• 概  述：

管式杀菌机组是根据用户工艺要求，在同一机组内同时进行加热、保温、热回收与冷却等工艺的多组套管组合换热蒸发器设备，具有换热效率高，结构紧凑，工作可靠，性能稳定，运行时间长，操作清洗维修方便等优点。设备的换热管内壁经抛光处理，物阻小，物料在高温情况下管壁结焦的现象得到很大改善，是板式杀菌机*的一种新型杀菌设备，广泛地应用于乳品、豆奶、果汁饮料、糖浆、酱油、酒类、醋类、药液等液态物料。

• 工作原理：

杀菌机是通过在高压下用过热水循环加热来对物料进行灭菌，除菌后按工艺要求保温，然后热回收、冷却逐步被降至工艺所需的温度。物料由前工序进入杀菌机平衡罐，进料泵将产品送入管式热交换单元进行预热，然后在管式热交换器中进行加热达到灭菌温度，产品须在保温管中保温一定的时间以取得预定的杀菌效果，产品经一级、二级或三级冷却后达到工艺所需的温度。一级冷却采用的是热回收方式，二级冷却采用冷却水冷却，三级采用冰水冷却。

• 设备组成及特点：

管式杀菌机组由管式换热器主机、物料平衡罐、物料泵、保持管、热水罐、热水泵、热水发生器、控制柜及电器元件等组成，系统设备具有如下特点。

1、杀菌不足自动返回管路，确保系统无菌性；

2、无菌阀，冷却管路连接法兰采用蒸汽保护；

3、加热介质与物料温差小，可实现温和加热；

4、使用触摸屏人机界面，实时控制液位、温度及工艺过程；  

5、采用热回收技术，提高热传输效率，节约能源；

6、系统安全性强，系统配件皆选用性能好，可靠性高的

7、采用镜面焊接技术，保持管道连接平滑，减少物料残留。

8、产品系统设计高度重视人身，设备安全，蒸汽，热水，物料等都有压力保护措施和报警系统。

9、换热管采用了波纹管，物料和换热介质都在湍流状态工作，换热效率高，结垢少、增长了杀菌机的连续工作的时间。

四、设备基本参数：

Tubular Type Sterilizer

Ⅰ. Introduction

   Widely used for kinds of dairy food,fruit juice, fruit jam,beverage,sugar syrup,soy,wine,vinegar,pharmacy fluid etc sterilization. This serial sterilizer included Tubular type sterilizer and Sleeve Type Sterilizer.

Ⅱ. Working Principle

Sterilizer will achieve sterilizer itself by hot water circulation heating under high pressure.after than,system will reduce the temperature suit for production,and then enter into production stage.The product flow into material tank of sterilizer after pre-treatment,firstly pumped into tubular heat exchange unit for pre-heating, when reached sterilization temperature by heating,it will keep insulation in a certain time for required sterilization effect.then product need to process one 1st stage and 2nd stage cooling for ideal filling temperature. 1st stage cooling adopt hot recycle method, 2nd stage is cooled by cooling water.

Ⅲ.Equipment construction and characteristic

System consist of material tank, tubular heat exchange, material pump, keeper,water storage tank,hot water pump ,hot water reactor,electric cabinet etc.

• Making sure system is aseptic,material will automatic back to the pipeline when sterilization not compley
• Aseptic valves and cooling pipeline connection flanges are adopt steam production.
• Realizing mild heating due to small temperature difference between material and heating medium.
• Control level and temperature in real time by using touch screen man-machine interface.
• Adopt hot recycle technology, improve heat exchange efficient,energy saving.
• System strongly safety,spare parts is stable and durable.
• Adopt mirror welding technology,ensure pipeline connection smoothly, reduce the material residual.
• Product designed with humanization with pressure production system and alarming system for steam,hot water and material.
• Inner pipeline adopt advanced polish technology, it can clean by itself, automatic sterilization,make sure system is aseptic.
• Heat exchange design with corrugated pipe that reducing scaling,improving the heat exchange efficient,increased working time because of fluid and heat medium are keeping turbulent situation working.
• Tubular Pasteurization and yogurt sterilizer can be customized according to user’s request. It suit for kinds of aseptic packing,for example:aseptic box packing, aseptic plastic film packing,aseptic bottle packing etc. Especially for liquid milk and beverage production.
