    Boiling dryer is used for boiling and drying of granular materials with particle size of 0.
    1-20mm, which is suitable for finished products and intermediates drying in pharmaceutical, food, light industry and chemical industries.
    Working principle Natural air under the guidance of the fan, through the purification cabinet, heater, in the material bed plate hole to form a high-speed air flow, and so that the material in a boiling state, in the gas-solid two-phase large-area contact process of the material in the rapid evaporation, so as to achieve drying
    .

    Working principle: boiling dryer is the use of air through the heat exchanger heating, the formation of hot air through the valve plate distribution into the host, wet material from the feeder into the dryer, due to the role of air pressure, the material in the dryer to form a boiling state, and with the hot air for extensive contact, so as to complete the material drying
    in a short time.

    Boiling dryer is the material in the fluidization of the same time by low-speed stirring, so as to avoid agglomeration, for high moisture content, viscous materials, its use of advantages are more prominent
    .

    Six operating procedures of boiling dryer: 1.
    Inspection before the equipment starts: Check whether the transmission part of the equipment can run smoothly and whether there are foreign objects interfering with the operation of
    the equipment.

    Check whether each lubrication part needs to be filled with lubricating oil
    .

    Check each steam valve for damage, internal leakage! 2.
    Bed-making: Before the equipment runs, it is necessary to lay dry salt of not less than 20cm on the aperture plate in the wind chamber, and the thickness of the salt layer is required to be uniform and flat
    .

    3.
    Equipment (warm bed) start-up: (1) first open the heat exchanger steam in and out of the valve, steam intake valve to open slowly, open the discharge steam condensate valve, so that the condensate can be discharged smoothly; (2) The equipment distribution cabinet is connected to the power supply and press the fan and blower buttons
    in turn.

    Wait for the internal heating of the equipment and monitor the operation of each equipment; (3) When the temperature rises to about 150 °C, turn on the feeding motor and start feeding
    .

    Then turn on the discharge motor! When adding materials, it must be smooth and continuous, and avoid more or less! It is strictly forbidden to interfere with the operation of the crusher with foreign objects when the feeding motor is running
    .

    4.
    Stop: Notify the front process before the boiling dryer is stopped, stop the discharge, close the feeding motor after adding no material in the hopper, and continue to dry the materials in the equipment! (1) If the equipment is running continuously, the materials in the equipment do not need to be cleared, and the steam intake valve, blower, induced fan, and discharge motor can be closed after the material is dried; (2) If the equipment is not running for a long time, the material in the equipment must be cleared clean, and after the material is dried, close the steam valve, open the tie plate below the outlet, and then close the blower, the induced fan, and the discharge motor after the material in the equipment is cleared! During the operation of the equipment, pay close attention to the operation of each transmission part, as well as the boiling state
    of the material in the wind chamber.

    5.
    Air volume adjustment: air volume adjustment is adjusted according to the actual situation of the material layer in the equipment
    .

    The size of the air volume should always be able to keep the material in the equipment boiling state and not too much blowing away The boiling dryer is used for boiling and drying of granular materials with a particle size of 0.
    1-20mm, which is suitable for the drying of finished products and intermediates in the pharmaceutical, food, light industry and chemical industries.

    The air volume should be so large that the material in the equipment should always be in a boiling state and not blown away too much
