The invention relates to a filtration and drying integrated device used in a rubber antiscorcher CTP production process and applications thereof. The device comprises a tank body, a bracket, a motor, a material feeding inlet, a product material outlet and a stirring facility, wherein, the tank body is arranged on the bracket; a heat-insulating jacket is arranged outside of the tank body, and the heat-insulating jacket is provided with a heat-insulating medium inlet and a heat-insulating medium outlet; a vacuum/nitrogen interface is arranged on the tank body, the bottom of the tank body is provided with a filtrate guiding out port, and a filtering screen plate is arranged in the lower part of the tank body near the filtrate guiding outlet. By using the filtration and drying integrated device of the invention, the operations of filtration and drying do not need to be switched so as to obtain a finished product, thus avoiding air contamination caused by volatilization solvent of the product exposed in the air in the process of switching operation; in addition, labor force can be saved, unit consumption of the solvent is significantly reduced, and equipment investment is also saved.
