Hot air circulating drying ovenIt is composed of angle steel, stainless steel plate and cold steel plate. Insulation layer is filled with high-density aluminum silicate cotton, high-density aluminum silicate cotton to ensure the insulation of the oven, but also to ensure the safety of users. Heater device azimuth but bottom, top or both sides. Use digital intelligent instrumentation to control the temperature. There are two kinds of hot air circulating oven airway design: Horizontal air supply and straight air supply. and the application range of hot air circulating oven is also very wide. Suitable for baking chemical gas and food processing to bake items, ink curing, paint film drying, etc., widely used in electronics, motors, communications, electroplating, plastics, metal chemicals, instruments, printing, pharmaceutical, PC board, powder, including immersion, spraying, glass, wood building materials and other fine baking, drying, tempering, preheating, shaping, processing, etc.; internal heat circulation, baking objects evenly heated.
1, hot air cycle oven size selection Studio size can be determined according to the size of the experimental items and how much. In the process of constant temperature drying, the quantity and placement of laboratory articles in the studio affect the uniformity of temperature in the working room. When the requirement of temperature uniformity is relatively high, it is suggested to reduce the number of specimens or select large types of ovens to ensure hot air convection in the working room. Refers to the production talent, from the appearance, the larger the volume, the more production talent will be, the higher the purchase cost, the size of production talent by some elements, such as: electric power size, production materials characteristics, production zui large space. Generally just look at the number of cars in the oven (the shelf of the baking pan, there is no need to bake the plate, such as chicken, duck and other drying), there are single door bikes, two cars, two four cars, four doors and eight cars, each car can put 10 baking trays, each baking plate size for the standard 640*460*50 (mm unit) size, Based on this, the required production size can be calculated and the appropriate oven should be selected.
2, hot air cycle oven temperature scale selection and the use of temperature between the use of temperature under 290 ℃, it is recommended to choose the Rt+10~300℃ temperature scale of the oven, when the use of temperature between 300℃~450℃, please choose 500 ℃ temperature of the high temperature oven (dryer); use temperature in 450℃~ 560 ℃, please choose a high temperature oven of 600 ℃ temperature
3, hot air circulation oven temperature, which is an important function. It is also an important goal to judge the quality of an oven. Oven in the constant temperature stage, although the temperature of the control instrument is generally relatively stable, but the temperature of each point in the box is different, which will form different directions of the sample heating different.
4, the type of material: the type of material resolution of the structure and characteristics of the oven, such as: materials for powdery, not to use hot air circulation oven, you can choose vacuum Drying box Series (wind may discharge materials with the wind oven). If you are not resistant to high temperature materials, these are to be noted.
5, hot oven structure type: Oven Air supply method is divided into horizontal air supply and straight air supply two kinds, according to the characteristics of self-materials to choose the appropriate structure.
