The invention discloses a soapstock solvent recycling process and equipment for miscella alkali refining output, relates to a soapstock treatment process and equipment for grease processing and production, and in particular to a soapstock solvent recycling process and equipment for miscella alkali refining output of rice bran and cottonseed grease. The equipment consists of a mixer, a heater, a falling film evaporator, a drier, a condenser, a water separation tank and the like which are connected in sequence. The process comprises the following steps: diluting, mixing, performing preheating treatment, performing evaporation pre-desolvation, performing drying treatment and performing condensation recycling. The equipment disclosed by the invention has the characteristics of being large in treatment capacity, simple in method, convenient to operate, capable of continuous production, low in production cost and the like, and particularly with respect to the treatment effect, the content of a solvent of treated soapstock is less than 800ppm, which is greatly less than national standards, so that later storage and transportation security is ensured, and multiple problems of conventional equipment and treatment processes are solved.
