The invention provides a process-improved novel
bamboo salt preparation method which comprises the following steps: firstly, mixing crude salt and bamboo ash, and putting the mixture into a high-temperature
smelting furnace for melting and calcining to remove
heavy metals, so as to obtain reinforced enriched high-temperature calcined
bamboo salt; and mixing the crude salt with the strengthened and enriched high-temperature calcined
bamboo salt to adjust the
water content, compactly loading into a bamboo tube, sealing, and baking to obtain the strengthened and enriched novel bamboo salt. The raw salt and the bamboo ash are mixed and melted to prepare reinforced enrichment type high-temperature calcined bamboo salt
powder, then the reinforced enrichment type high-temperature calcined bamboo salt
powder is added into the raw salt in a
solid or liquid mode to be baked, non-water-soluble mineral substance melting and water-soluble mineral substance melting are superposed, and trace elements in bamboo materials and salt are efficiently fused, so that the content of water in the bamboo materials is increased, and the quality of the bamboo materials is improved. The penetration of mineral substances in the bamboo tube into the salt column is increased by assisting the
modes of
puncturing the inner wall of the bamboo tube and chamfering the upper end surface, the
alkalinity and mineral content of the once-baked bamboo salt can reach the traditional multiple baking level, the bamboo salt quality is remarkably improved, the baking frequency and the production time are reduced, the production efficiency is improved, and the cost is reduced.
