Molded release method for molten state autumn ice salt

Abstract

This invention discloses a method for molding and demolding molten autumn ice salt, comprising the following steps: S1, high-temperature heating: solid salt frosting is placed into a crucible, filling it to 70%-90% of its volume, and then the crucible is fed into a high-temperature box furnace via an automatic feeding device for heating to 800-1000℃; S2, heat preservation treatment: the salt frosting is kept at 800-1000℃ for 1-4 hours; S3, cooling and molding: the crucible containing the molten salt frosting is moved to a cooling area, first cooled at a controlled rate using a circulating water cooler, and then exposed to an annular temperature for natural cooling, causing the molten salt frosting to solidify into salt blocks; S4, demolding assistance: the crucible is gently vibrated using a mechanical auxiliary device to help loosen the salt blocks from the crucible; S5, pouring and collecting: the molded salt blocks are automatically slid into a preset collection container under gravity. The beneficial effect of this invention is that the optimized cooling and demolding process facilitates rapid demolding of autumn ice salt.
