旋流气流强化干燥机

一、工作原理及应用范围介绍 Introduction of Working Principle and Scope of Application

旋流气流干燥机设有内筒体与外筒体两部分，内筒为直筒，外筒为上大下小倒锥形，物料经前段的直管式或脉冲式气流初步干燥后，从旋流强化干燥器的上部切向进入干燥室。物料跟随高速旋转热风向下部进行旋转运动，从而达到强化传热传质干燥之目的。到达底部后的粗料以及大部分物料存积于底部出料口部经出料口排出；微粉随尾气由内筒向上运动经旋风分离后收集下来。广泛适用于医药、食品、化工、生物工程、冶金粉末、环保等分散性比较好的颗粒、粉末等滤饼物料的快速强化烘干。

The spiral pneumatic drier is composed of inner cylinder and outer cylinder. The inner cylinder is a straight cylinder and the outer one is a small inverted cone. After being preliminarily dried by front straight or pulse airflow, the material tangentially enters the drying chamber from the top of spiral intensification drier. The material rotates downwards following the high-speed rotating hot air, so as to achieve the purpose of intensification heat and mass transfer drying. After reaching the bottom, the coarse material and most of material deposit at the bottom discharge opening and are discharged through the discharge opening; micro powder moves with the tail air to the top from the inner cylinder and is collected after separated by whirlwind. The equipment is widely applicable to quick intensification drying of filter cake materials of granules and powder with great dispersity in pharmaceuticals, food, chemical engineering, bioengineering, metallurgical powder and environmental protection.

二、特点Characteristics

1.物料先经强化分散后进行干燥，成品均匀，不会产生块状、团状物料。

2.物料先经气流烘干后再经旋流二次强化干燥，干燥效率高，属组合式干燥，比传统单一气流干燥所占空间小，干燥效率高。

3.由于采用旋转气流结构就延长了物料的干燥时间，产品的终含水可得到保障。

4.比传统的组合式干燥装置节省能源、节省工程造价、节省操作人员。

1.The material is dried after the enhancing dispersion. The finished products are uniform and there will be no clotty and lumpy material.

2.The material is dried by the airflow firstly and goes into secondary intensification drying by rotational flow. The drying efficiency is high. The equipment is a combined drying system and takes up less space than the conventional single pneumatic drying, with high drying efficiency.

3.The rotating pneumatic structure prolongs the drying time of material, so the products can maintain final water content.

4.Compared with the traditional combined drying devices, this equipment saves energy, project cost and operating personnel.
