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

濕物料干燥過程是怎樣的呢?

What is the drying process of wet materials?

干燥機內(nèi)高溫空氣和低溫物料的存在,當熱空氣穩(wěn)定地流過濕物料表面時,在熱空氣和物料之間會產(chǎn)生熱傳遞動力.熱風通過交叉通風將熱量傳遞給物料,物料利用熱量將其中的水氣化,然后被氣流連續(xù)帶走,物料的濕度比不斷下降.當它降平衡水含量時,它完成了干燥過程.

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

在干燥設備干燥的干燥過程中,存在著傳熱和傳質(zhì)兩個相互作用的過程.

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

傳熱是指熱空氣將熱量傳遞到物料上,用于氣化物料中的水分和熱量;傳質(zhì)是將物料中的水分蒸發(fā)并混合到熱空氣中,然后通過減少水分含量進行干燥.

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
