Drying Solutions for Efficient Sludge Management: Unveiling the Power of Hollow Blade Dryers

The hollow blade dryer does not use hot air, so that solvent recovery, energy consumption, and environmental control are in an ideal and easy-to-handle state. It is especially suitable for solvents that need to be recovered, and flammable and oxidizable heat-sensitive materials. It has been widely used in fine chemicals, petrochemicals and dye industries. The uniformity of temperature, humidity and mixing degree in the axial range allows the equipment to be used for heating or melting, or for some solid material reactions.

The solvent recovery hollow paddle dryer includes a feed tank, a feed hopper, a feed reducer, and a stirring paddle. The feed hopper and the tank are connected to the upper and lower ends of the feed tank respectively. There is a There is a discharge valve, a feed valve is provided between the feed hopper and the feed tank, the stirring paddle is set in the feed tank, and the feed reducer is fixedly installed on the feed tank and is linked with the stirring paddle.

The rotary driving part is set to drive the linkage shaft to rotate, and the scraping part is driven to rotate synchronously while the linkage shaft rotates. When people need to dry the material, the material falls onto the heating and evaporation device. As the heating and evaporation device works, the wet material The solvent vapor contained in the alcohol lamp will rise layer by layer, enter the condenser through the demister, and achieve heat exchange with the coolant in the condenser to complete the vapor-liquid conversion process; the solid matter will remain in the heating evaporation device On the top, driven by the scraper that rotates with the linkage shaft, it enters the next umbrella-shaped heating mechanism through the blanking hole, and then is further heated and evaporated to separate the solid and liquid. The material passes through the multi-layer umbrella-shaped heating mechanism continuously. The solid-liquid separation process enables more efficient drying and recovery of valuable pharmaceutical residues, effectively avoiding environmental pollution and realizing the recycling and reuse of materials.
