Abstract:
     A chitin polyose is prepared form chitin and clkali solution in weight ratio of 1:(2-20) through feeding them in the first stage of multi-stage microwave fluidized bed and obtaining the chitin polyose from the output in last stage. Said alkali solution has a 30-60% concentration and is at 60-160 deg.c of temp. in the reaction process. Its equipment is composed of microwave fluidized bed, microwave cavity, thermometer, baffle and fluid distributor, material discharge valve, and material feed and discharge tubes. Its advantages include high quality and productivity of product, low energy consumption and no wastes discharge.
