  • the compression apparatus 1 will be available in different sizes and follows a concept of modularity; especially the output module 31 is designed to be changed easily. Therefore fastening means are formed after the same concept no matter which output module 31 is chosen in order to fasten the output module 31 easy to the compacting apparatus 1. Unlike other waste compactors, this machine does not need a separate sheet to cover the piston during its movement. This function is realized by the filling part. When the filling part is closed, it is flush with the arcuate front wall and forms an arcuate front wall. Together the filling part and the compression chamber form a large pressing channel. Further, the compactor has a large filling chamber due to the piston's moving angle. The waste material can be filled directly into the compaction chamber, because the piston moves up above the filling opening. Therefore, the filling chamber and the compaction chamber are practically the same and the whole space between the output module and the upper position of the piston can be seen as a large filling chamber.
  • Smaller machines especially these for being used in a kitchen comprises a power transmission such as:
  • the door 40 may be constructed in different ways Through a top hinged door. Through a sliding door. A drum, which empties into the pressing chamber through tilting it. A tipping device, which lifts bins or boxes and empties them into the opening. Through a conveyor belt. It has to stop while the piston is not in upper position or there has to be a separate pre-filling chamber. The door 40 may also be excluded if the filling opening is directly connected to an input module.
