Windrow turners and moisture management systems from Midwest Bio-Systems create high-quality humified compost

Aeromaster composting equipment by Midwest Bio-Systems meets or exceeds the four basic requirements to creating high-quality, humified organic compost:

Remove carbon dioxide and and replace with oxygen — the breakdown of organic matter and subsequent build-up of humus is a microbial process that uses oxygen and generates carbon dioxide. Continued replacement of the oxygen allows this to continue effectively. The advanced drum and tine design of the Aeromaster compost turners consistently replaces almost all of the built-up carbon dioxide with fresh oxygen.

Manage Temperature — considerable heat is generated during the composting process, especially during the breakdown phase. The temperature of the windrow should be maintained at a proper level to allow the right microbes to survive and thrive while eliminating harmful bacteria. Aeromaster compost turners, working within our Advanced Composting system (ACS), remove excess heat and allow the windrows to continue the breakdown of organic matter into compost.

Manage Moisture — Like oxygen, proper moisture, evenly distributed, is essential to the breakdown and build-up phases of the composting process. The unique turning action of Aeromaster compost turners expose the surface of each compost particle to the water spray coating all sides. This water coating action is particularly valuable when you are inoculating the compost with supplemental microbial species. The microbes can only work on the material they touch, so the more thorough the coating action, the more effective the inoculation process.

Mix Without Pulverizing —- composting is the management of a microbial process. In addition to managing carbon dioxide, temperature, and moisture, the turning process must mix the material exposing particle surfaces to moisture and microbes without turning the material to dust. Aeromaster compost turners thoroughly mix windrow materials without pulverizing the humus crumb structure that develops during the build-up phase of the composting process.

If you use an Aeromaster windrow turner, you will:

  • Be a one-man operation with operator control from the cab
  • Be able to water each particle of the compost as opposed to just the outside of a row
  • Be able to inoculate (add proven beneficial microbes) to compost evenly throughout the row at a low cost per cubic yard
  • Maximize humus formation due to its variable drum speeds and tine shape
  • Maximize carbon dioxide/oxygen exchange — tests show carbon dioxide levels at maximum before turning and minimum immediately after turning
  • Mix and blend composted materials — move perimeter materials to the center and center materials to the outside of a windrow. The tine shape promotes mixing and blending as opposed to cutting and shredding. This maximizes humus formation in the finished product. Microbes, not machinery, make compost.
  • Be able to remove the drum from the row at any time — our turners enable the composter to walk into the middle of a row and examine the profile at any time. If compost is too wet to turn that day, pull out and move on as opposed to digging yourself out.
  • Have proven durability — It is not uncommon for customers to report that they’ve gone 2-3 years without downtime, excepting normal maintenance.
  • Have a low hourly cost of operation — Midwest Bio-Systems’ equipment has an hourly cost of operation as low as one-half the industry standard.
  • Produce compost that sells at prices well above the industry average
