一、用　途：

I. Purpose:

101型电热干燥箱最高工作温度为300℃ ，它适用于烘焙、干燥热处理或其他加热用。也是试验室常备仪器。

With the maximum working temperature of 300℃, the electric thermostatic drier model 101 is designed for baking, dry heat treatment or other types of heating. It is the standing instrument in laboratory.

干燥箱之工作温度可由室温升30℃起至最高温度止，在此范围内可任意选定工作温度，选定后可借箱内自动控制系统使温度恒温。

The working temperature of drier may change from room temperature to 30℃ and then to the maximum temperature. Within this range, the working temperature can be arbitrarily selected. The selected temperature will be kept constant by automatic control system inside the drier.

202型电热干燥箱工作室内借冷热空气之比重动向促成对流，使室内温度更加均匀。

Electric drier model 202 realizes the convection by taking advantage of the density difference between hot and cold air inside the working chamber so as to make the chamber temperature more uniform.

101A型鼓风干燥箱装有电动鼓风机，促使室内热空气机械对流，使室内温度更加均匀。

Provided with a motor-driven blower, the drier model 101A realize the mechanical convection of hot air inside chamber so as to make the chamber temperature more uniform.

本干燥箱结构精密，控温灵敏度准确，操作简便，工矿及大专院校科学研究单位等均可采用。

This drier with precise structure and correct temperature sensitivity that is easy to operate is suitable for industrial and mining enterprises and research body of universities and colleges etc.

101A型鼓风干燥箱是101型的更新产品。采用了最新颖的数字显示仪表进行测温，控温灵敏、准确、清晰直观。101A型除测温、控温方式和101型不同外，其余结构、性能、规格均相同。

Drier model 101A, as the updated version of model 101, adopts the latest digital instruments for temperature measurement, featuring sensitive, accurate and straightforward temperature control. The temperature measurement and control mode of model 101A is different from that of model 101; however, other structures, properties and specifications are the same as model 101.

二、结　构：

II. Structure

干燥箱由薄钢板构成，工作室与箱体外壳间以玻璃纤维作保温层材料。箱门间有一玻璃窗，以供观察工作内之情况。

The drying cabinet is made of steel sheet. The insulating layer between working chamber and cabinet shell is composed of fiber glass. Between the doors is a glass window for observing the situation in working chamber.

开启箱顶排气阀可使工作室温之冷热空气得以对流交换，温度控制用热胀式控制器或数字显示仪表自动恒温调节。全部电气操纵设备均装于箱侧控制层内。控制层有侧门可以卸下，以备检查或修理线路时用。

The convective exchange between hot and cold air inside working chamber is available when the exhaust valve at the top of cabinet is opened. Automatic thermostatic control is realized through thermal expansion controller or digital instruments. All electric control devices are mounted in control layer beside the cabinet which is provided with a removable side door for line check or maintenance.

电热器装于箱体内工作窒下，共分二组，即“加热1”、“加热2”，并有指示灯指示加热工作，灯亮表示电热器工作，灯灭表示加热停止。

Electric heaters are mounted in two groups, i.e. HEATING 1 and HEATING 2, under working chamber, and are provided with indicator lamps; ON means the heater is working, and OFF means the heating has been stopped.
