| description | The invention relates to a method and a device for sublimation drying of maltol. The device is characterized by comprising a sublimation kettle, wherein a dryer is additionally arranged in the front of the sublimation kettle; the outlet of the bottom part of the dryer is connected with the inlet of the sublimation kettle through a pipeline; the outlet of the upper part of the dryer is connected with a condenser through a pipeline; and the condenser is connected with a distillate outlet groove through a pipeline. The method comprises the following steps: a, pouring coarse-crystalline maltol from a previous centrifugation section into the dryer, and heating the dryer to 60 to 80 DEG C through a pre-decompression method; and b, evaporating trichloromethane and water from the coarse-crystalline maltol, allowing the trichloromethane and the water to enter the condenser from the outlet of the upper part of the dryer, carrying out condensation, allowing condensed trichloromethane and condensed water to enter the dis |
