The development is based on a unique waste mill design that includes a system for flowing water through the grinder's central axis. The water is pumped through an internal sprinkler located in the drainage and grinding area and directed directly to the system's center of activity. The water streams help push and transport food residues accumulated in the sink to the drainage and grinding area, improving waste flow into the grinder and supporting efficient operation. In addition, the water flow helps to reduce the accumulation of food residues in the work area and maintains a continuous flow during operation.
