Abstract: The invention relates to a projectile launching device (10). The invention also relates to a method of using a projectile launching device (10).

Abstract: A method and apparatus are disclosed for drying and pelletizing organic material such as animal waste, sewage and the like. The organic material is dried in two stages using a high temperature, rotating primary drying drum, and a lower temperature secondary louvred drying drum. The primary drum includes an inlet section and an outlet section. The inlet section includes a plurality of transverse chain curtains for increased heat transfer to the organic material, for breaking up the organic material and for cleaning the sides of the drum. The primary drum outlet section includes a plurality of vanes angularly attached to the inside of the drum to form an auger to retain the material in the drum until it is partially dried to a desired level. The organic material is then transported to the secondary louvred dryer. The louvred dryer includes an input section, an output section and a central pelletizing section formed by adjacent portions of the input and output sections.
