The utility model has the advantages of safe and convenient use, novel and beautiful shape, mirror stainless steel studio, electric heating constant temperature blast drying oven, and an electric fan is installed in the oven to accelerate the convection of hot air and make the temperature in the oven uniform. The water vapor conducive to the evaporation of the articles in the box is accelerated to escape into the air outside the box to improve the drying efficiency.

The electric heating constant temperature blast drying oven is composed of the following parts:

1. Built in circulating air duct and fan;

2. The temperature controller can be an intelligent program temperature controller;

3. Air conditioning mode of blast drying oven: forced internal circulation ventilation and balanced temperature regulation;

4. The shell of the drying oven is made of high-quality cold-rolled plate, with plastic spraying treatment on the surface, beautiful shape and moderate thickness;

5. The blast drying oven adopts microcomputer temperature controller with digital display and temperature control protection, with timing function;

6. Hot air circulation system: it is composed of a fan that can operate continuously at high temperature and a suitable air duct to ensure uniform temperature in the studio

7. The tank is made of mirror stainless steel (or wire drawing plate) by argon arc welding. It is equipped with two-layer shelf with adjustable height to facilitate the placement of samples;

8. The electrical control system has overtemperature protection function. The microcomputer p.i.d temperature controller with digital display has timing function;

The electric heating constant temperature blast drying oven is suitable for measuring moisture in coal, drying articles, drying heat treatment and other heating purposes. The series equipment adopts digital display temperature regulator for temperature control. It has the advantages of sensitive temperature control, simple operation and reliable performance. The digital directly displays the working temperature, which is intuitive and easy to read. The working room temperature can be kept at any constant temperature between room temperature and 300 ℃; It can automatically cut off the power supply and protect the equipment and test object。
