Abstract
The invention discloses a method for preparing sodium chloride colored salt by adopting inorganic pigment. The method comprises the following steps: taking sodium chloride and inorganic pigment as base stocks; first placing the sodium chloride in a container, then adding the inorganic pigment, stirring to perform preliminary mixing, and adding silica and/or magnesium stearate for further mixing; pouring the mixture in advanced mixing equipment for mixing again, so as to allow the materials to be fully mixed; and packing the fully mixed materials into packing bags, sealing and packaging the packing bags, and placing the bags in dry and cool places for storage. According to the invention, the sodium chloride, as the main raw material, is fully mixed with the selected inorganic pigment through a physical method, so as to obtain colored salt particle or powder which is bright in color, uniform in size and durable. Moreover, the inorganic pigment is nontoxic or low in toxicity, the raw materials for production are wide in source, the production procedure is short, and the process is simple.
