10 Tons Annual Output of Vitamin B12 Process Design(fermentation workshop)
ABSTRACT
Vitamin B12 is the necessary element for the tissue metabolism of human body , it is also the important factor for humans and other mammals to maintain growth and can promote the growth of red blood cells。Vitamin B12 can be used for the clinical treatment of pernicious anemia and recovery of hematopoietic function, it also can be used for the adjuvant therapy of neuritis。
This dissertation is discussed of 10 tons annual output of Vitamin B12 process design。I select the P. Denitrificans as the strain for aerobic fermentation and use three-stage fermentation。Through consulting literatures and patents to determine the process flow, and draw the process flow diagram;then proceed the material and energy balance。According to the calculation results,I accomplish the professional equipment lectotype and general equipment design and draw the main equipment structure diagram;finally,I finish the layout of fermentation workshop equipment and draw the workshop floor-plan。
