刮板式换热器借助刮板搅动料液并清洁传热面以加快传热效率,不仅适合低粘度料液,尤其适合高粘度或含颗粒料液快速换热.高粘度料液由于粘度大或流动慢,在超高温杀菌处理中,一般换热器的传热面易生成焦化膜,采用刮板式换热器最适合.在乳品、蕃茄酱、豆乳和果汁等无菌包装食品生产中,常将数台刮板式换热器串联,输送泵将料液连续通过换热器进行预热、杀菌和冷却,然后无菌包装.进行 Scraper heat exchanger with a scraper to stir the feed liquid and clean the heat transfer surface to speed up the heat transfer efficiency, not only for low viscosity liquid, especially for high viscosity or particle containing liquid rapid heat exchange. High viscosity liquid due to viscosity or Flow slow, in the ultra-high temperature sterilization, the general heat exchanger surface heat generation easy to generate coking film, scraper heat exchanger is most suitable in the dairy, tomato sauce, soy milk and fruit juice and other aseptic packaging food production, often Several scraper heat exchangers are connected in series, the feed pump continuously pre-heats, sterilizes and cools the feed liquid through the heat exchanger, and then aseptically packs.
