The factory design of annual production capacity of 500 tons nutritional power of germinated grains
Abstract：This design is primarily for the annual production capacity of 500 tons nutritional power of germinated grains. First, to understand the germination and physicochemical property of grain. Second, design the production process. Using germinated corn, rice, wheat as raw material, malt dextrin, powder, as auxiliary material, experiencing the process of sorting, two times of mixing, two times of mixture, extrusion, sterilization, packaging, to get the nutritional power of germinated grains. Make sure that technological process is simple and workable. Next, according to the production process and production output, draw up class production. What’s more, work out the material balance, equipment selection, calculation of water and electricity consumption. Then, start to design, including the general layout design, the production workshop design, aiming to formulate reasonable plant layout and plant planning. Finally, make the technical and economic analysis; calculate the cost, profit; analysis the profit and loss balance and operation safety, and then, draw the conclusion.
Key words: nutritional power of germinated grains；plant design；extrusion
