某罐头食品厂有日产5吨/日卧式片冰机三台。在使用过程中,经常发生不制冷、不产冰的故障,致使罐头生产受到很大的影响。 片冰机中的蒸发器(即制冰部分)是片冰机的主要部件。这种特殊的蒸发器是由双层钢板焊接成夹层园筒。制冷剂在此夹层中蒸发吸热,当水被喷淋到筒表面上时,便迅速凝结成冰。借助于刮刀把冰壳刮下即成小块的片冰。 A canned food factory Nissan 5 tons / day horizontal ice flake three. In the process of using, often without refrigeration, ice-producing failure, resulting in canned production has been greatly affected. The ice maker’s evaporator (ice making section) is the main component of the ice maker. This special evaporator is double-layer steel welded into a laminated cylinder. The refrigerant evaporates and absorbs heat in this interlayer, and when water is sprayed onto the surface of the cylinder, it quickly condenses into ice. Scraping the ice shell with the help of a scraper to make a small piece of ice.
