NOVELTY - Co-production of biomass fuel straw starch comprises making starch from corn husk, i.e., corncob; making the starch into starch glue; crushing the corn straw or plant biomass; mixing the powder with the starch glue; and rolling the mixture so as to form the blocky fuel.    USE - Co-production method of biomass fuel straw starch.    ADVANTAGE - The corn husk starch glue is taken as binder to produce the biomass compression fuel. The request for crushing degree of the biomass is low. Electric energy can be saved. The corn husk can be used fully; and additional value is increased. Production efficiency of the biomass fuel such as the straws is improved. Production cost is reduced.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for device for the co-production of biomass fuel straw starch comprising a starch heating pot (1), a mashing cylinder, a straw crusher and an extruder. The heating pot includes a hollow pot body (4). The lower space of the pot body is mounted with a fire gate (5) having a combustion chamber (6). A feeding port (15) is arranged at one side of the upper part of the pot body. A pressing cover is arranged above the feeding port, and the other side is provided with a discharging port (9). The discharging port is internally mounted with an auger (11). Outer end of the discharging port is mounted with an oblique pressing cover (10). The pot body is internally provided with a vertical rotating shaft (8). Upper end of the rotating shaft is connected with output end of motor (14) while lower part is provided with an outer screw thread. A sieving sheet (7) is configured. Upper section of the rotating shaft is provided with an umbrella gear (13) that is engaged with the umbrella gear at the shaft end of the auger; and the upper part of the rotating shaft is provided with a pawl wheel (12).
