Finishing Drawer on Sun-Mar Excel


Advantages of a Separate Compost Finishing Drawer

  • Composting can be completed in the drawer without contamination by fresh waste.
  • Compost in the drawer is gradually dried until ready for removal
  • Finished compost can be simply and safely removed

The finishing drawer serves two functions: to receive the compost in an easily accessible isolated container, and complete the composting and sanitation processes.


All Units Except CENTREX 3000 Series

  • Compost drops directly into the finishing drawer when the drum is rotated backwards.
  • Composting is completed in the drawer, where it is isolated from fresh waste and possible contamination.
  • While in the drawer, the compost is surrounded by a stream of drying air, and gradually dries prior to removal.
  • The pull out finishing drawer is removed by hand (no tools or screws are needed), and the sanitized compost may be emptied whenever more compost is to be extracted from the drum.
  • For seasonal units, several drawers may be removed in the Spring, reducing the compost level in the drum to 6-8" to make room for next year’s operation.


CENTREX 3000 Series Units Only

  • CENTREX 3000 series units have a collection chamber and one finishing drawer, both are easily removed.
  • The collection chamber is located on the far-right hand side of the unit. When the bio-drum is just over half full, finished compost will automatically fall into the collection chamber.
  • The finishing drawer is located in the front and on the right hand side of the unit.
  • To maximize capacity in seasonal use applications, the finishing drawer provides a means to reduce the compost level in the bio-drum beyond what automatically occurs with the collection chamber. By releasing the drum locker and rotating the drum backwards multiple drawers of compost can be removed at the very start of the season.
