    Product Details

    Principle

    When the fuel is burned in firebox,high temperature smoke gas is produced.Those smoke gas is sent by hot air furnace which has strong exchange heating function to dried air. After quantity of heat is emanated, hot fueling gas temperature is decreased to 25o°C and those gas are exhausted by fan. Fresh air is sent to hot air furnace by selected blow fan machine. After absorbed heating energy, when air temperature reaches to specific degree, it is sent to outlet of hot air, while hot air temperature meet the highest limited point, the burner will stop burning automatically or turn to small fire burning, when hot air temperature decreases to the lowest preseted degree, burner start running again, the speed of heating can be adjusted by air inlet valve.

    Applications

    This equipment main function are heating and removing damp. It is widely applied in agricultural, medical and chemical industry, such as grain, seeds, feedstuff, fruits,dehydrated vegetable, mushroom, agaric, white fungus, tea, tobacco leaf, foodstuff,medicines, chemical raw materials.

    Features

    • Convenient operation and low labor cost.
    • Structure compact and small occupied area.
    • Advanced burning machine, fuel can be fully consumed, no environment pollution.

    Frequently Asked Questions (FAQ)
    What is the main function of this hot air furnace?
    The main functions of this equipment are heating and removing dampness. It is designed to provide clean hot air for drying various agricultural, medical, and chemical materials.
    How does the temperature control system work?
    The system features automatic regulation. When the hot air temperature reaches the highest preset limit, the burner stops automatically or switches to a small fire. When the temperature drops to the lowest preset degree, the burner restarts. Heating speed can also be adjusted via the air inlet valve.
    What industries can use this equipment?
    It is widely used in agricultural, medical, and chemical industries for drying grains, seeds, feedstuffs, fruits, dehydrated vegetables, mushrooms, tea, tobacco leaves, foodstuffs, medicines, and chemical raw materials.
    Is the combustion process environmentally friendly?
    Yes. The furnace features an advanced burning machine that ensures fuel is fully consumed, resulting in high thermal efficiency and no environmental pollution.
    How do I choose the correct model for my production needs?
    You can choose the model based on your required heat supply capacity (ranging from 1 to 360 x10⁴ kcal/h) and fuel consumption rates. Please refer to the Technical Parameters table above for detailed specifications.
