概 述
工業廢鹽自頂部加料口進入螺旋床內，在周向激振力及重力的作用下，使工業廢鹽沿螺旋床自上而下跳躍運動，直至層出料:同時，潔凈的熱風由螺旋床底部進入，與分布在床上的工業廢鹽進行充分的傳熱和傳質后，由頂部排濕口排出。從而使工業廢鹽達到了干燥的目的。該產品主要適用于中藥丸劑的干燥，也適用于化工、制藥、食品、塑料、建材、飼料等行業的顆粒狀、短條狀、球狀物料的干燥。
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.
特點
熱風多次穿過工業廢鹽層，與工業廢鹽送向流動，使熱交換充分，熱效率高。
結構緊湊，占地面積小。
工業廢鹽在床內停留時間可以調節，操作方便。
工業廢鹽沿螺旋床自上而下作圓周運動的同時，自身也產生跳躍，從而增加了工業廢鹽與熱風的接觸面，增強了干燥效果。
連續的進出料適合于流水線生產，并且易于達到“GMP”規范，可代替傳統的箱式干燥。
對工業廢鹽的表面及形狀基本沒有損傷，不僅保證了丸劑的圓度，而且大大地降低了丸劑的破碎率。.
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.
