一．用途及主要特點 Application and main characteristic
顆粒料的冷卻是制粒工段中不可缺少的工序。逆流式冷卻器能將70℃-90℃的顆粒料冷卻到略高于室溫3℃-5℃，并能將水分降到安全水分（≤12.5%），便于顆粒料的運輸、儲藏和保管。
逆流式冷卻器是目前國際上比較先進的一種新型冷卻器，它是利用逆流冷卻原理對高溫、高濕度的顆粒料進行冷卻。環(huán)境風(fēng)垂直穿過料層，先與料層相接觸，逐步變熱的熱風(fēng)與熱料相接觸，風(fēng)流方向與料流方向相反，使顆粒料順向逐步冷卻，可避免因冷風(fēng)與高溫顆粒料直接接觸，使顆粒驟冷而引起的顆粒表面開裂?？諝鈴钠涞撞咳轿贿M入冷卻器，進風(fēng)面積大，利用率高，能耗低，操作簡便，冷卻效果顯著。
與濕物料接觸部位采用不銹鋼材料制造，使用壽命長,自動運行，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.
