An automatic dissolution system and a method thereof are provided to reduce the time to find a condition in order to secure a parameter for fixed hours. An automatic dissolution method comprises: a step of authenticating an administrator by using ID and password(S30); a step of storing parameters passively inputted at solution works of a specific product and specific material(S50); a step of performing a solution work by using the stored parameters(S60); a step of selecting the parameter of optimum from the stored parameters several times by performing the solution work depending on parameters(S80); and a step of automatically performing the solution work of the specific material by using the parameter of optimum(S90).
