一、工作原理與應(yīng)用范圍介紹

Introduction of Working Principle and Scope of Application

熱風(fēng)循環(huán)烘箱以空氣為載體，用蒸汽或電能或熱風(fēng)爐作熱源，將從箱外進入的冷空氣經(jīng)過熱源加熱升溫后，再強制循環(huán)分層平流經(jīng)過烘盤與烘盤內(nèi)物料進行熱交換，并帶走物料蒸發(fā)產(chǎn)生的濕氣（水分），又回到熱交換器再次加熱升溫。如此多次循環(huán)，當(dāng)熱空氣濕含量增大到一定程度后就開啟排濕閥，排除部分高濕熱風(fēng)，補充部分低溫新的冷風(fēng)，從而達到連續(xù)干燥之目的。

熱風(fēng)循環(huán)烘箱是一種通用性的干燥設(shè)備，廣泛適用于各種行業(yè)。工作時將粉狀、顆粒狀、塊狀、膏糊狀、稀狀、水狀物料以及濃縮液置于烘盤中進行烘干，適用范圍非常廣。

  Hot air circulating oven uses air as the carrier and steam, electricity or hot blast heater as the heat source. The cold air from the outside of oven, after being heated by the heat source, will pass through the materials in the baking tray for heat exchange after the layering through forced circulation to remove the wet (moisture) generated in evaporation of materials. Then, the air will return to the heat exchange for re-heating. After several rounds of such circulation, when the moisture content in the hot air reaches a certain amount, the moisture removal valve will be opened to remove part of the wet and hot air and supplement part of the low-temperature new cold air, achieving the purpose of continuous drying.

    Hot air circulating oven is a kind of common drying equipment widely applicable to various industries. In operation, powdery, granular, blocky, pasty, dilute, aqueous materials and concentrates are placed in the baking tray for drying. It is also call universal drier.

二、特點Characteristics   

    1、熱風(fēng)在烘箱內(nèi)循環(huán)，熱效率高，節(jié)約能源。

    2、烘箱內(nèi)設(shè)有風(fēng)道，強制層流通風(fēng)，箱內(nèi)溫度均勻，物料干燥均勻。

    3、烘箱運轉(zhuǎn)平穩(wěn)，自動控溫，使用、安裝、維修方便。

    4、可干燥各種不同規(guī)格、不同批次物料，是理想的通用干燥設(shè)備。

     1.The hot air circulates in the oven, ensuring high heat efficiency and saving energy.

    2.The oven is set with an air channel for forced ventilation. The temperature in the oven is uniform and the materials are uniformly dry.

    3.The oven operates stably and is subject to automatic temperature control. It is easy to use, install and maintain.

    4.It can dry materials of different specifications and batches and is the ideal universal drying equipment.
