干燥機的有何特點(diǎn)？

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

熱空氣由入口管以適宜的噴動(dòng)速度從干燥機底部進(jìn)入攪拌粉碎干燥室，對物料產(chǎn)生強烈的剪切、吹浮、旋轉作用，于是物料受到離心、剪切、碰撞、摩擦而被微?；?，強化了傳質(zhì)傳熱。在干燥機底部，較大較濕的顆粒團在攪拌器的作用下被機械破碎，濕含量較低、顆粒度較小的顆粒被旋轉氣流夾帶上升，在上升過(guò)程中進(jìn)一步干燥，由于氣固兩相作旋轉流動(dòng)，固相慣性大于氣相，固氣兩相間的相對速度較大，強化兩相間的傳質(zhì)傳熱，所以該機生產(chǎn)強度高。

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.
