NOVELTY - Biomass briquette machine comprises a biomass hopper, an additive hopper, a mixer and briquette machine component. The biomass hopper is fixed to a feed controller, stirrer, stirring controller, a dehydrating chamber, a scraping plate, a water outlet and a discharging switch composition. The feeding controller is fixed to biomass hopper. The top part of biomass hopper is set with stirrer, stirring controllers, mixers and dehydrating chamber. The scraping plate is fixed to dehydrating chamber, and is set with a circular hole. The scraping plate is set close to inner wall of dehydrating chamber.    USE - The machine is useful in high-density compression processing of livestock and poultry manure, straw and silage.    ADVANTAGE - The machine facilitates uniform addition of additives, is environmental friendly, and performs dehydration of biomass under high temperature and high pressure conditions.    DETAILED DESCRIPTION - Biomass briquette machine comprises a biomass hopper, an additive hopper, a mixer and briquette machine components. The biomass hopper is connected to a feed controller, stirrer, stirring controllers, a dehydrating chamber, a scraping plate, a water outlet and a discharging switch composition. The feeding controller is connected to the biomass hopper. The upper part of the biomass hopper is mounted with stirrer, stirring controllers, mixers and dehydrating chamber. The scraping plate is connected to dehydrating chamber, and is set with a circular hole. The scraping plate is set close to the inner wall of dehydrating chamber. The inner part of the biomass hopper is mounted with the dehydrating chamber. There is a gap between the dehydrating chamber and the biomass hopper. The gap is connected to the water outlet. The bottom part of the biomass hopper is mounted with a discharging switch by an infrared controller. The additive hopper is connected to feeding controller, stirrer, additive hopper, a material feeding pan. The circular hole is set at the bottom plate of the additive hopper. The feeding controller is connected to the additive hopper. The mixer is connected to the material feeding pan. There are two material feeding pans set on a fourth sector which are mutually diagonal to each other, and is mounted on the upper surface of the circular hole. A channel is formed by a rotating circular hole and circular hole located on the additive hopper. The circular hole of the additive hopper is larger than the hole placed on the bottom plate of the material feeding pan, by 2-4 mm. The entire bottom part of the hopper is uniformly distributed with holes. The additives include coal powder, fuel auxiliary agent, catalysts, molding agent, microbial active agents, microelements and growth regulating agent. The upper part two ends of the mixer is connected to biomass hopper and discharge switch respectively by a flexible material discharge port. The bottom plate of the additive hopper is set with circular hole. The inner part of the mixer is mounted with a screw extruder. The screw extruder is mounted with a biomass material discharge port. The briquette machine is installed around with a hot steam coil. The biomass material discharge port is connected to the mixer. The biomass material discharge port and the mixer are connected to each other.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the biomass briquette machine.
