浸梗机水温加热系统的改进

摘要

针对浸梗机水温加热盘管长期使用后粘结水垢导致加热性能下降问题,对浸梗机水温加热系统进行了改进.将盘管加热方式改进为采用蒸汽喷射器对洗梗水直接喷射蒸汽的加热方式.改进后水温从25℃提高到60℃所需时间从21～28 min降低到14 min,当水温下降达到设定下限时蒸汽加温系统能够及时提高温度,改善了水温加热设备的性能,保证了物料加工过程中水温的恒定.%The scale deposit on the water heating coil in stem dipping machine will deteriorate heatingrnperformance, therefore the coil-heating was replaced by direct steam ejecting. After improvement, the time forrnraising temperature from 25 ℃ to 60 ℃ reduced from 21-28 to 14 minutes. When water temperature approachedrnto lower control limit, steam heating system raised it timely. The constant water temperature during stemrnprocessing was guaranteed.
