Double Drum Design a complete revolution in composting methods!

With the Autoflow technology your finished compost discharges automatically through the side door as the drum rotates. You can keep putting your kitchen scraps and garden & lawn waste in the top loading door.  The Sun-Mar 400 does the mixing for you.  The Sun-Mar is a gardener’s dream.  It makes composting fun and effortless, and you have the satisfaction of knowing you are doing the right thing by recycling your kitchen and yard waste.

The Patented double drum design works to move compost along the main outer drum as it rotates, and back through the inner drum before dropping from the output port. The Autoflow provides optimum composting conditions, mixing, oxygenating and distributing moisture throughout.

Features & Specifications:

The 200 and 400 units consist of an outer main drum, with an inner drum inside it. It sits in a cradle for support. As the drum rotates the materials move the length of the drum and are picked up by the inner drum and pushed along to the output port, where you harvest your finished product. Materials can be added continually for a constant working and supply of compost, making it easy to be the best recycler in your neighborhood.  The difference between the 200 and the 400 models is the length of the unit. The longer unit will take longer to move the materials down the length of the drum.  Because there are so few pieces to assemble, it takes only a few minutes to put it together.

• The 400 model only 5 minutes to assemble!  Just snaps together.


• No waiting for batches to finish


• Pest resistant


• Easy to load and turn


• Compost discharges automatically when you open the end cap.

Benefits of Composting Your Kitchen and Yard Waste Include healthier plants, because of the improved soil structure and additional nutrients in the compost. Reduced waste disposal costs because of less waste going out. FREE source of fertilizer!  Reduced water bills, because soil mixed with compost retains water better than regular soil.

Composting

Keep the compost moist and oxygenated. This means rotating the drum regularly, to add oxygen, and adding water when the compost gets dry.  Keep the compost warm.  This is not usually a concern because the compost in the drum and the drum's insulating properties keep heat in.  Aim for the right carbon/nitrogen ratio.

Adding a mixture of kitchen and regular yard waste is effective, but for better, faster results, add carbon-rich material (browns) like sawdust, straw, dry leaves, or wood chips.   These balance the nitrogen-rich green material and kitchen waste. Chop up the waste if possible: the smaller it is, the faster the breakdowns process. If you use only kitchen waste, you may need  to add bulking material or pre-composted material to help with oxygen penetration as the drum rotates.
