Citric Acid Project Introduction
The end result is citric acid. to create citric acid from unprocessed corn to the finished good. The procedure must go through a few crucial steps. Some of the stages include grinding, liquefaction, sterilisation, filtration, fermentation, decolorization, refinement, and evaporation. After working through each stage and attaining the requisite quality, the corn exits the system. After that, the process continues on to the next stage. Corn is crushed and turned into slurry via dry milling. The liquefaction process is where corn slurry proceeds after this stage. Mend the temperature. And for a predetermined period of time, the liquefaction moves into the filtration area. After being sterilised, the crude protein is filtered before going into the fermentation system. Keep the fermentation at a specific temperature, at the precise time, and with enough oxygen. The fermentation mash then moves on to the neutralisation stage of the citric acid production after filtering. The filtered bacterial residue is combined with the liquefied crude protein for drying as animal feed after washing and recovering the citric acid. Calcium hydrogen citrate precipitation is produced in the neutralisation section using two rounds of neutralisation and filtration. Primary citric acid is made after acid hydrolysis and extraction. Citric acid is refined and purified by having the coloured impurities, odd smell, and other impurity ions removed using decolorization, filtering, and a continuous ion exchange system. The certified anhydrous citric acid is then prepared by centrifugal separation, drying, and vacuum evaporation crystallisation. Centrifugal separation, which separates the crystal and drying, is the following step. The citric acid attains its highest level of purity during the drying process. Finally, a qualified citric acid monohydrate product was developed.
