Nowadays, the raw materials of many products are dried by wet materials, and the use of dryer is required in this process. The wet materials are dried into dry materials by dryer, so as to be produced and processed as raw materials. Today, the drying equipment manufacturer explained the drying process of wet materials to you, hoping to help you

湿物料干燥过程是怎样的呢?

What is the drying process of wet materials?

干燥机内高温空气和低温物料的存在,当热空气稳定地流过湿物料表面时,在热空气和物料之间会产生热传递动力.热风通过交叉通风将热量传递给物料,物料利用热量将其中的水气化,然后被气流连续带走,物料的湿度比不断下降.当它降平衡水含量时,它完成了干燥过程.

Due to the existence of high-temperature air and low-temperature materials in the dryer, when the hot air stably flows through the surface of wet materials, heat transfer power will be generated between the hot air and materials. The hot air will transfer heat to the materials through cross ventilation. The materials will use heat to vaporize the water therein, and then be continuously taken away by the air flow, and the humidity ratio of the materials will continue to decline. When it drops to the equilibrium water content, It completes the drying process

在干燥设备干燥的干燥过程中,存在着传热和传质两个相互作用的过程.

In the drying process of drying equipment, there are two interactive processes of heat and mass transfer

传热是指热空气将热量传递到物料上,用于气化物料中的水分和热量;传质是将物料中的水分蒸发并混合到热空气中,然后通过减少水分含量进行干燥.

Heat transfer refers to that hot air transfers heat to materials for gasification of moisture and heat in materials; Mass transfer is to evaporate and mix the moisture in the material into hot air, and then dry it by reducing the moisture content
