干燥机的有何特点？

干燥机械是集干燥、粉碎、筛分于一体的新型连续式干燥设备，山东干燥机械具有设计合理，结构紧凑，使用范围广，可用于颜料、染料、精细化工、农药、肥料、饲料、食品、医药、电子等化工轻工诸行业，含水量高的糊状物料干燥。达到高效快速、节能、小设备大生产，连续化操作的目的。

Drying machinery is a new type of continuous drying equipment which integrates drying, crushing and screening. Shandong drying machinery has reasonable design, compact structure and wide application range. It can be used in pigment, dye, fine chemical industry, pesticide, fertilizer, feed, food, medicine, electronics and other chemical and light industries. It has high water content paste material drying. To achieve the purpose of high efficiency, fast, energy saving, large-scale production of small equipment, continuous operation

热空气由入口管以适宜的喷动速度从干燥机底部进入搅拌粉碎干燥室，对物料产生强烈的剪切、吹浮、旋转作用，于是物料受到离心、剪切、碰撞、摩擦而被微粒化，强化了传质传热。在干燥机底部，较大较湿的颗粒团在搅拌器的作用下被机械破碎，湿含量较低、颗粒度较小的颗粒被旋转气流夹带上升，在上升过程中进一步干燥，由于气固两相作旋转流动，固相惯性大于气相，固气两相间的相对速度较大，强化两相间的传质传热，所以该机生产强度高。

The hot air enters the stirring and crushing drying chamber from the bottom of the dryer at an appropriate spouting speed from the inlet pipe, which exerts strong shearing, blowing and rotating effects on the materials. As a result, the materials are granulated by centrifugation, shearing, collision and friction, thus enhancing mass and heat transfer. At the bottom of the dryer, larger and wetter particles are mechanically broken under the action of the agitator. The particles with lower moisture content and smaller particle size are entrained and lifted by the rotating air flow. During the rising process, the gas-solid two-phase flow is rotating, the inertia of the solid phase is greater than that of the gas phase, and the relative velocity of the solid-gas phase is relatively large, which strengthens the mass transfer and heat transfer between the two phases High strength.
