The invention relates to a high-temperature heat pump drying system and a control method for Silica Gel particles with ultra-low moisture content, belonging to the technical field of Silica Gel particles drying processing, the drying chamber comprises a drying chamber, a vacuum generating mechanism maintaining the vacuum state of the drying chamber and a heat pump drying mechanism providing the drying environment inside the drying chamber, the heat pump drying mechanism comprises a condenser located inside the drying chamber. The inlet and outlet pipes of the condenser are connected in series with a compressor, an expansion valve and an evaporator after passing through the drying chamber wall, the invention solves the technical problem in the prior art that the drying efficiency of the Silica Gel particles is low and the continuous production is disadvantageous.
