Such as life activities glucose is indispensable substances, directly involved in the metabolic processes in the human body . To supplement the body of water and sugar , with rehydration , the supply of energy , added sugar, cardiac diuretic , detoxification effect . However, in a variety of pharmaceutical and food production process, the sugar concentration is low , resulting in low productivity ,so that it can not meet production needs, which requires a large amount of water distilled off by concentration to obtain a high concentration of sugar . The design uses four cross-flow effect evaporation , evaporation equipment for the use of forced circulation outside heated falling film evaporator , the design of process and design, strength design and structural design , drawing sugar evaporation process flow diagram , equipment and facade layout and the heating chamber , the separation chamber , liquid distributor and atmospheric condensers and other equipment assembly drawings and parts diagram .
