一、工作原理与应用范围介绍

Introduction of Working Principle and Scope of Application

热风循环烘箱以空气为载体，用蒸汽或电能或热风炉作热源，将从箱外进入的冷空气经过热源加热升温后，再强制循环分层平流经过烘盘与烘盘内物料进行热交换，并带走物料蒸发产生的湿气（水分），又回到热交换器再次加热升温。如此多次循环，当热空气湿含量增大到一定程度后就开启排湿阀，排除部分高湿热风，补充部分低温新的冷风，从而达到连续干燥之目的。

热风循环烘箱是一种通用性的干燥设备，广泛适用于各种行业。工作时将粉状、颗粒状、块状、膏糊状、稀状、水状物料以及浓缩液置于烘盘中进行烘干，适用范围非常广。

  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、特点Characteristics   

    1、热风在烘箱内循环，热效率高，节约能源。

    2、烘箱内设有风道，强制层流通风，箱内温度均匀，物料干燥均匀。

    3、烘箱运转平稳，自动控温，使用、安装、维修方便。

    4、可干燥各种不同规格、不同批次物料，是理想的通用干燥设备。

     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.
