1. , a kind of vibrating mixed flow drying method, this method may further comprise the steps:

  • (1) will need dry material to send in the vibrating mixed flow drying system, trickle down on ground floor vibration drying bed by the air-locked type dispenser;

    (2) before in material is sent into the vibrating mixed flow drying system or simultaneously, thermal current is sent in the drying machine by the air inlet of vibrating mixed flow drying system bottom;

    (3) after thermal current passed each vibration drying bed, upruss to exhaust outlet was discharged;

    (4) sending into material in the vibrating mixed flow drying system contacts with upstream thermal current in ground floor vibration drying bed and carries out heat exchange and water evaporates, material carries out preheating simultaneously and by thermal current through the vibratory liquefaction of ground floor vibration drying bed, and the thermal current that makes progress also makes needs the dry further fluidisation of material;

    (5) vibration ground floor vibration drying bed makes the material that is not fluidized by the unrestrained second layer vibration drying bed that is delivered to of stock guide;

    (6) being transported to material on the second layer vibration drying bed contacts with upstream thermal current in second layer vibration drying bed and carries out heat exchange and water evaporates, material carries out preheating simultaneously and by thermal current through the vibratory liquefaction of second layer vibration drying bed, and the thermal current that makes progress also makes needs the dry further fluidisation of material;

    (7) the vibration second vibration drying bed makes material trickle down by stock guide and is delivered to the 3rd layer of vibration drying bed;

    Repeat the above-mentioned operation that is associated with first, second vibration drying bed, make material through and the 3rd ..., the operation that is associated of n layer vibration drying bed, material is transported downwards until the vibration drying bed to the bottom, and wherein n is the natural number more than or equal to 3;

    (8) material is discharged via the air-locked type discharger;

    It is characterized in that;

    material further carries out heat exchange and water evaporates with the thermal current that makes progress in the process that moves downward;

    Wet feed in material group under the effect of unrestrained and vibration by loose fluidisation and increased contact area with air-flow, the sieve aperture that less material particles sees through on the sieve plate is trickled down to lower floor'"'"'s vibration drying bed, and the material that sees through sieve aperture is further dry by thermal current again in the process that falls, material in the while upper strata vibration drying bed is owing to small particles material is unrestrained, make the material particles gap become big, thermal current percolation intensity increases;

    Wherein said each vibration drying bed becomes " it " font to come and go installation, and described each vibration drying bed comprises the bed body that has sieve plate, is arranged with the sieve aperture that a large amount of apertures are 0.5mm-30mm on the sieve plate.
