  2. Loading: Fill the ARK-1000L chamber to the recommended operating volume.
  3. Automatic Cycle: The unit automatically handles mixing, aeration, and temperature control over 24–48 hours.
  4. Discharge: Separate solid compost and liquid fertilizer, utilizing the automatic valve for liquid release.
  5. Optional Curing: Perform a short maturation period if required before final use or sale.

Maintenance & Service Guidelines

  • Daily: Check sensors, review control panel status, and clear any visible obstructions.
  • Weekly: Inspect and clean aeration pipes; verify that blowers and exhaust fans operate correctly.
  • Monthly: Lubricate bearings, check motor mountings, and test electric valves along with alarm functions.
  • Quarterly: Calibrate temperature and humidity sensors, inspect the structural body, and service the heating system if installed.
  • Annually: Schedule a professional service inspection for motors, blowers, and control systems.

Target Applications

  • Hotels & Resorts: Efficiently manage high volumes of food waste from buffets and kitchens.
  • Restaurants & Food Courts: Lower waste collection costs while turning scraps into useful organic material.
