【正文】 a selfJNA squeeze cooked rice machine type. It is divided into the working process of maturation and a twostage extrusion molding silk. During the graduation project, the analysis of selfJNA squeeze cooked rice wiretype working principle, the main pulley speed to plete a large calculation, the aging and crowded spiral helical wire speed required. Understanding of the design of the overall structure and the role of the main parts. Barrel aging aging in place there is the role of spiral from aging, overcrowded wire cylinder has put squeeze squeeze wire spiral wire from the role, adjusting the control valve can be be of good quality rice. Aperture of a different powder materials can be a variety of rough mirror, fine rice varieties article. Drawing the main parts drawing and assembly drawing. Keywords: pulley, cylinder ripening, aging spiral, crowded wire cylinder, crowded spiral wire, transmission pipe, control valve, a material powder mirror.
