The invention provides a process for continuously producing solid salt from a salt solution. The process comprises the following steps that: firstly, the pressurized salt solution is put in a dispersing room, which makes the salt solution pressurized when the salt solution passes the dispersing room; under the pressure, the salt solution is dispersed into micro water beads of which the volumes areless than or equal to 15 cubic millimeters and then enter a salifying room; secondly, the pressurized air is fed in a heater, heated and then enters the salifying room from at least two directions tofully mix with the dispersed salt solution; thirdly, the mixture obtained in the salifying room is heated to vaporize water, and the mixture is crystallized to obtain the solid salt; fourthly, the crystallized solid salt enters a salt collector for collection; and fifthly, the waste heat in the third step can be recycled, and simultaneously the vaporized water is condensed for recycling; therefore, the process has the characteristics of continuousness, scale, low energy consumption, high efficiency and no environmental pollution.
