Gluconic production methods : raw materials calcium gluconate using sulfuric acid hydrolysis, in gluconic acid solution. After filtration to remove calcium sulfate precipitation, reuse and barium hydroxide solution of oxalic acid purification and separation settlement, the solution to remove the SO42-and Ca2 +. Then through ion exchange resins, to further purify the gluconic acid solution. Solution will be enriched to 80% -85% concentration, joined glucono-delta-lactone seeds, and continue to concentrate crystallization, centrifugal separation; Washable; Drying products.
