Hot air circulating drying ovenGenerally there is a heating pipe, there is a circulating fan oven can be called hot air circulation oven, because no matter what structure of the oven, the wind direction level is still straight, in the final analysis is the hot air in the inside circulation, so can be called hot air circulation oven, such as electric blast oven, open door high temperature sterilization oven and so on. However, the general occupation of the said hot air circulation oven is still specific to the oven shown above, other ovens are from the above image oven evolution, such as the requirements of high temperature sterilization, fan change wind cold standardized ring fan, front and rear door, air duct also made changes, become to open the door high-temperature sterilization oven. The hot air cycle shown in the figure above is divided into five standard types. Respectively is single door bike, two two cars, two four cars, sanmen six cars, four doors eight cars.
The air circulation system is selected by means of fan circulation, and the wind circulation is uniform and efficient. Wind source by the circulating wind motor (choose no contact switch) to drive the wind wheel through the heater, and the hot air sent out, and then through the airway to the oven chamber, and then the use of air inhalation duct become wind source re-circulation, heating use. Ensure indoor temperature uniformity. When the temperature value attack swings caused by the opening and closing action, the Air supply circulation system is agile to restore the operating state until the set temperature value is reached. Hot air Circulation oven 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 position but bottom, top or both sides.
Hot air circulation oven used in medicine, chemical industry, food, agricultural and sideline products, aquatic products, light industry and other industries material heating curing, dry dehydration. such as materials, Chinese herbal tablets, dipping ointment, powders, granules, dehydrated vegetables and so on.
Temperature of hot air circulating oven:
Hot air circulation oven use of a wide range of the scale, can dry a variety of industrial materials, is a general drying equipment, the general hot air cycle oven temperature scale of room temperature ~ +250℃, high temperature type for room temperature ~ +500℃
1, hot air in the oven circulation, high thermal efficiency, energy saving.
2, the use of forced ventilation effect, the oven with air duct, material drying uniform.
3, the oven work smoothly. Automatic temperature control, easy maintenance of the device.
4, the application of a wide range of materials can be dried, is the ambition of universal drying equipment.
