Continuous flow sol technology

The invention discloses a continuous flow sol process. The process comprises the following steps: step 1, adding purified water, gelatin and glycerol into a sol tank for swelling; 2, the sol tank for swelling is controlled to stir purified water, gelatin and glycerin in the sol tank for swelling to obtain a glue solution, and meanwhile, the working current of a stirring motor of the sol tank for swelling is monitored; when the working current of a stirring motor of the sol tank for swelling reaches a preset swelling current threshold value, conveying the glue solution in the sol tank for swelling into the sol tank for dissolving; step 3, controlling the sol tank for dissolving to heat and stir the glue solution, and vacuumizing the sol tank for dissolving; when defoaming of the glue solution in the sol tank for dissolving is completed, vacuumizing is stopped, and the moisture and viscosity of the glue solution in the sol tank for dissolving are measured on line; when the moisture and the viscosity of the glue
