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(guò)程是怎樣的呢?

What is the drying process of wet materials?

干燥機內高溫空氣和低溫物料的存在,當熱空氣穩定地流過(guò)濕物料表面時(shí),在熱空氣和物料之間會(huì )產(chǎn)生熱傳遞動(dòng)力.熱風(fēng)通過(guò)交叉通風(fēng)將熱量傳遞給物料,物料利用熱量將其中的水氣化,然后被氣流連續帶走,物料的濕度比不斷下降.當它降平衡水含量時(shí),它完成了干燥過(guò)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(guò)程中,存在著(zhù)傳熱和傳質(zhì)兩個(gè)相互作用的過(guò)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(guò)減少水分含量進(jìn)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
