Green Mountain Technologies Daritech Environmental Largest 8x40 drum Used for Recycling Manure into Bedding Moving into food waste 16. Green Mountain Technologies Auger mixes food on surface into hot compost mass The food cooks and softens in the compost The next mixing smears the cooked food into the bulk material How the Inclined Auger Mixes and Grinds 17. Green Mountain Technologies Aeration & Biofiltration Process air collected from the Earth Tub headspace is blown thru a biofilter container to remove odors Biofilter media is a mix of leaf mulch with wood chips and lime Odors are degraded by microbes growing on biofilter media 18. Green Mountain Technologies The Development of the Earth Flow Same inclined auger concept as Earth Tub Automated Mixing Plug flow design 10-100 yard capacity 19. Green Mountain Technologies Mixing/Shearing Action of Auger 20. Green Mountain Technologies Earth Flow Innovations Solid floor eliminates leachate Inclined auger moves material backwards Pressure of auger movement shears material 21. Green Mountain Technologies Material Flow thru the Earth Flow Food scraps loaded by bucket loader or tote tipper Inclined auger pulls material into hot compost mix Auger incline causes compost to move to the rear of the bin Discharge door swings open to allow discharge of finished compost 22. Green Mountain Technologies Greenhouse Enclosure Provides heat gain in Winter Traps compost odors for scrubbing Keeps out rain Prevents access to machinery. 23. Green Mountain Technologies Installation in NYC Highrise 24. Green Mountain Technologies Earth Flow Control Panel Controls X-Y Motion of Auger Provides programmable mixing cycles to allow aeration thru mixing Allows multiple patterns for complete mixing Utilizes VFDs for speed control and electrical efficiency 25.
