The invention discloses drying equipment in order to solve the problems that traditional drying equipment is poor in drying effect and high in energy consumption. The drying equipment comprises a box body, a drying chamber, an air supply cavity, an air return cavity and a dehumidification chamber. A rotation wheel system for continuous dehumidification is arranged in the dehumidification chamber, dry air is generated through dehumidification of the rotation wheel, the needed drying temperature is adjusted through an air supply temperature controller in the air supply cavity, and the dry air is sent into the drying chamber to absorb moisture in articles to be dehumidified. Due to the fact that the dry air basically contains no moisture, the dry air can sufficiently evaporate the moisture in the articles, and the drying effect is good; due to the fact that a circulation air pipe is arranged in the dehumidification chamber, the air can be circulated multiple times in the sealed drying chamber and the sealed dehumidification chamber, the dry air is fully utilized and energy consumption is greatly lowered.
