概 述

　　工业废盐自顶部加料口进入螺旋床内，在周向激振力及重力的作用下，使工业废盐沿螺旋床自上而下跳跃运动，直至层出料:同时，洁净的热风由螺旋床底部进入，与分布在床上的工业废盐进行充分的传热和传质后，由顶部排湿口排出。从而使工业废盐达到了干燥的目的。该产品主要适用于中药丸剂的干燥，也适用于化工、制药、食品、塑料、建材、饲料等行业的颗粒状、短条状、球状物料的干燥。

　　The industrial waste salt enters the spiral bed from the top of the screw bed by feeding the outletUnder the action of circumferential exciting force and gravity the industrial waste salt jumps up and down along the spiral bed until the bottom discharges. At the same time the clean hot air enters from the bottom of the spiral bed and after sufficien heat and mass transfer with the industrial waste salt 　distributed on the bed it moves from the top to the bottom. Drain outlet So that the industrial waste salt has reached the purpose of drying.This product is mainly suitable for the drying of traditionalChinese medicine pillst isalso suitable for the drying of granular short strip and spherical materials in chemical pharmaceutical food,plastics. building materials and feedindustries.

　　特点

　　热风多次穿过工业废盐层，与工业废盐送向流动，使热交换充分，热效率高。

　　结构紧凑，占地面积小。

　　工业废盐在床内停留时间可以调节，操作方便。

　　工业废盐沿螺旋床自上而下作圆周运动的同时，自身也产生跳跃，从而增加了工业废盐与热风的接触面，增强了干燥效果。

　　连续的进出料适合于流水线生产，并且易于达到“GMP”规范，可代替传统的箱式干燥。

　　对工业废盐的表面及形状基本没有损伤，不仅保证了丸剂的圆度，而且大大地降低了丸剂的破碎率。.

　　Hot air goes through the materials and flows conversely with the materials,which make the contact thoroughly.

　　The structure is compact with small cover area.

　　The time of matenals stay in bed can be adjustedwhich isvery convenient.

　　OThe materials move from up to down that make thorough contact with the hot air. so it improves the drving auality The continuous feeding and discharging is suitable for the production line and can meet the GMP requirement.It can well replace the traditional chamber drier.

　　The surface and shape of industrial waste saltare basically not damaged,which not only ensures the roundness of the pills,but also greatly reduces the breakage rate of the pills.
