The design of raw materials used potato fermentation, simply potato mills, water-paste, adding a small amount of direct α-amylase liquefaction, sterilization, cooling, fermentation can be vaccinated. Preparation of citric acid normally used as raw materials dried potato. Potato moisture content of 10% to 15%, about 70 percent of starch, protein about 6 percent. Potato raw materials in the protein can be used as source of nitrogen for cell growth. Potato raw materials containing iron, magnesium, potassium, calcium of inorganic salt, optional black Aspergillus niger C0527 is not sensitive to these ingredients, it need not do any pretreatment of the raw materials. The design of a good gas liquids deep fermentation, dry calcium citrate extraction technology production. The two methods are more popular domestic production methods, has a great deal of practical experience, easy to operate, the risk small. As the design for the saccharification and fermentation workshop the design, the two workshops focused on the process, the selection of equipment. Through the whole plant material balance, energy balance workshop, identified glycosylation, fermentation workshop major equipment fermenter, seed tanks, pipelines and workshops in the design and selection. And the whole plant and facility layout.
The design also includes Fermentor, The factory plan, Shop floor plan, Flow Chart.
Key words: Potato Deep-seated aerobic fermentation Aspergillus niger Citric acid Equipment Design and Selection
