一．用途及主要特点 Application and main characteristic
颗粒料的冷却是制粒工段中不可缺少的工序。逆流式冷却器能将70℃-90℃的颗粒料冷却到略高于室温3℃-5℃，并能将水分降到安全水分（≤12.5%），便于颗粒料的运输、储藏和保管。
逆流式冷却器是目前国际上比较先进的一种新型冷却器，它是利用逆流冷却原理对高温、高湿度的颗粒料进行冷却。环境风垂直穿过料层，先与料层相接触，逐步变热的热风与热料相接触，风流方向与料流方向相反，使颗粒料顺向逐步冷却，可避免因冷风与高温颗粒料直接接触，使颗粒骤冷而引起的颗粒表面开裂。空气从其底部全方位进入冷却器，进风面积大，利用率高，能耗低，操作简便，冷却效果显著。
与湿物料接触部位采用不锈钢材料制造，使用寿命长,自动运行，安全可靠。
Cooling station particulate material is indispensable granulation step. Counterflow cooler can 70 ℃ -90 ℃ particles cooled to just above room temperature 3 ℃ -5 ℃, and can secure the water drops of water (≤ 12.5%), ease of particulate material transport, storage and safekeeping.
Counterflow chiller is currently the more advanced a new cooler, it is the use of counterflow cooling principle for high temperature, high humidity pellet cooling. Vertical wind through the material layer, the first layer in contact with the material, and gradually becomes hot hot hot material in contact with the opposite direction of flow and material flow direction, so that the forward gradually cooled pellets, can avoid the cold and high temperature Pellets direct contact quenching of the particles caused by the particle surface cracking. Round into the cooler air from the bottom, into the wind area, high efficiency, low energy consumption, easy operation, the cooling effect is remarkable.
With wet material contact parts made of stainless steel, long life, automatic operation, safe and reliable.
