| 工作原理： 滚筒干燥机是一种内加热传导型转动连续干燥设备。旋转的滚筒通过其下部料槽，粘附着一厚度的料膜，热量通过管道输送至滚筒内壁，传导到滚筒外壁，再传导给料膜，使料膜中的湿得到蒸发、脱湿、使含湿分的物料得到干燥。干燥好的物料被装置在滚筒表面的刮刀铲离滚筒，到置于刮刀下方的螺旋输送器，通过螺旋输送器将干物料集中、包装 Working Principle： Drum dryer is a kind of rotating continuous drying equipment with internal heating conducting-style. Certain thickness of materials film attach to the drum from material liquid vessel under the drum. Heat is transferred to the internal wall of the cylinder through pipes and then to the external wall and to materials film, to evaporate the moisture in materials film so as to dry materials. Dried products are then scraped off by the blade fitted on the surface of the cylinder, fall down to the spiral conveyor under the blade, and are conveyed, collected and packed. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| 性能特点： 1 、热效率高。因滚筒干燥机传热机理属热传导，传热方向在整个操作周期中保持*，除盖散热和热辐射损失外，其余热量全部都用于筒料膜湿分的蒸发上，热效率可达70%-80%。 2 、操作弹性大，适用性广。可调整滚筒干燥机的诸多干燥因素。如进料的浓度、涂料料膜的厚度、加热介质的温度、滚筒的转动速度等，都可以改变滚筒干燥机的干燥效率，且诸多因素互无牵连。这给滚筒干燥操作带来很大的方便，使之能适应多种物料的干燥和不同产量的要求。 3 、干燥时间短。物料的干燥周期一般只有10-300秒，在适合于热敏性物料。若将滚筒干燥机设置在真空器中，则可在减压条件下运行。 4 、干燥速率大。由于涂料抹于筒壁的料膜很薄，一般在0.3-1.5mm，且传热、传质方向*，料膜表面可保持20-70kg?H2O/m2?h 的蒸发强 Characteristics： 1.High heat efficiency. The principle of heat transfer of the cylinder dryer is heat conduction and the conducting direction keeps identical in the whole operation circle. Except heat loss of end cover and radiation loss, all heat can be used for evaporation of wet materials on the wall the cylinder. The efficiency can reach 70-80%. 2.Large operation elasticity and wide application. Various drying factors of the dryer can be adjusted, such as concentration of feeding liquid/thickness of material film, temperature of heating medium, rotating speed of the drum etc. which can change drying speed of the under dryer. As these factors have no interrelations each other, it brings great convenience to dry operation and makes it applicable to dry various materials and to meet different requirements of production. 3.Short drying period. The drying period of materials is normally 10 to 300 seconds, so it is suitable for heat-sensitive materials. It also can be pressure reducing operated if it is put in vacuum vessel. 4.Fast drying rate. As film of materials coated on the wall of the cylinder is very thin. Normal, thickness is 0.3 to 1.5mm, plus directions of heat and mass transmitting are identical, the evaporation strength on the surface of the film can be 20-70 kg.H2O/m2.h. 适应物料 适用于化工、染料、制药、食品、冶金等行业液体或较粘稠物料的干燥 Material to be dried It is suitable for drying liquid raw materials or thick liquid in chemical, dyestuff, pharmaceutical, foodstuff, metallurgy and so on industries | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
