ABSTRACT:Technological design of outputting 5 tons of Lentinan per year, which use entinus edodes as material. The key parts of the design are the technologic calculation of rectifier in rectification workshop and the selection of type of its assistant design includes two parts: instruction and blueprint. The instruction mainly includes the method of the extract of Lentinan vial and the process flow; the analysis of feasibility of building of the plant; the instruction of plane arrangement of the whole plant ; the instruction of design of rectification workshop ; design of non-technology parts:the project of water supply, heating, draught, lighting, safety, sanitation, antisepsis, the disposal of pollution, environmental main parts of the instruction are technologic calculation of the rectifier in rectification workshop and the selection of type of its assistant equipment , and in these parts , material balance and heat balance calculation and lots of experiential formulas are used as references.
KEY WORDS:Lentinus edodes, Lentinan vial , design of rectification rectifier, The rectifier equipments school pit,design of type of its assistant equipment
