    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

    How does the hot air furnace exchange heat?
    The system burns fuel in the firebox to produce high-temperature smoke gas. This gas goes through a strong heat exchange process inside the furnace to heat fresh air. The cooled fueling gas is then safely exhausted at around 250°C.
    What applications is this equipment suitable for?
    It is widely used for heating and damp removal in agricultural, medical, and chemical industries. Common materials processed include grains, seeds, fruits, dehydrated vegetables, mushrooms, tea, tobacco, and chemical raw materials.
    How does the temperature control system work?
    The system features automated temperature control. When the hot air reaches the preset high limit, the burner stops or switches to a small fire. Once the temperature drops to the lowest preset limit, the burner automatically restarts.
    Is this hot air furnace environmentally friendly?
    Yes. It features an advanced burning machine that ensures fuel is fully consumed, resulting in high thermal efficiency and no environmental pollution.
    What are the space and labor requirements for operation?
    The equipment is designed with a compact structure that occupies a small footprint. It offers convenient operation, which helps keep labor costs to a minimum.
    How is the heating speed adjusted?
    The heating speed of the furnace can be easily adjusted manually by operating the air inlet valve to control the airflow.
