CT-C hot air circulation oven


Hot air circulation oven:

Hot air circulation oven generally has heat pipes, and the oven with circulating fan can be called hot air circulation oven, because no matter what the structure of the oven, the wind direction is horizontal or vertical, in the final analysis, it is hot air circulation oven, so it can be called hot air circulation oven, such as electric blast oven, high temperature sterilization oven to open the door. However, most of the hot air circulation ovens in the general industry refer to the oven as shown in the above figure, and other ovens are evolved from the oven in the above figure, such as with the requirements of high temperature sterilization, the fan is changed into an air-cooled standardized ring fan, the front and back doors, the air duct has also been changed, and it has become a high-temperature sterilization oven. The hot air circulation shown above is divided into five standard models. They're single-door bikes, two doors, two cars, two doors, four cars, three doors, six cars, four doors, eight cars.


Hot air circulation oven air circulation system adopts fan circulation air supply mode, the air circulation is uniform and efficient. The air source is driven by the circulating air supply motor (using a non-contact switch) to drive the wind wheel through the heater, and the hot air is sent out through the air duct to the inner chamber of the oven, and then the used air is sucked into the air duct to become the air source for re-circulation and heating. Ensure room temperature uniformity. When the temperature value swings due to the opening and closing action, the air supply circulation system quickly recovers the operating state until the set temperature value is reached.


The hot air circulation oven is composed of Angle steel, stainless steel plate and cold steel plate.

The insulation layer is filled with high-density aluminum silicate cotton, which ensures the insulation of the oven and ensures the safety of the user.

The heater can be installed at the bottom, top or sides.


Hot air circulation oven is used for heating and curing, drying and dewatering of materials in pharmaceutical, chemical, food, agricultural and sideline products, aquatic products, light industry and other industries. Such as raw materials, Chinese medicine pieces, extract, powder, particles, dehydrated vegetables, etc.


Hot air oven is suitable for baking chemical gases and food processing to be baked goods, curing ink, drying paint film, etc., widely used in electronics, motors, communications, electroplating, plastics, hardware chemicals, instruments, printing, pharmaceutical, PC board, powder, including dipping, spraying, glass, wood building materials, precision baking, drying, tempering, preheating, shaping, processing, etc.; Internal heat circulation, baking objects are heated evenly.


1, heating heat source: steam, electricity, far infrared, electric steam dual purpose.

2, the use of temperature: steam heating: 50-140℃, up to 150℃. Electric, far infrared heating temperature 50-350℃.

5, equipped with electric heating according to type I calculation 15kw, practical 5-8kW /h.

6. Special requirements are indicated at the time of ordering.

7, the use of temperature greater than 140 ° C or less than 60 ° C, to indicate when ordering.

8, the factory factory drying car, drying tray size is uniform, can be interchangeable.

9. Size of baking tray: 460×640×45


1, hot air circulation in the oven, high thermal efficiency, energy saving.

2, the use of forced ventilation, the oven is equipped with an air duct, the material dry evenly.

3. The oven runs smoothly. Automatic temperature control, easy installation and maintenance.

4, wide range of application, can dry a variety of materials, is the ideal general drying equipment.

Temperature of hot air circulation oven:

Hot air circulation oven has a wide range of applications, can dry a variety of industrial materials, is a general drying equipment, general hot air circulation

The temperature range of the ring oven is room temperature ~ +250℃, and the high temperature type is room temperature ~ +500℃
