In addition, the digestor interfaces with standard farm machinery to support the loading and unloading of the unit. The BioDigestor TM operates in batch mode and produces high quality, clean compost from manure in a period of 3 - 6 days. The sooner in the process separation occurs, the cleaner the liquid effluent. Liquids, with reduced nutrient content, can be sent to the lagoon, or treated further and released as ordinance allows. The digestor is loaded while rotating to ensure even mass distribution.
Air is drawn through the open-ended vessel by an exhaust fan mounted at the lower rear end.
The compost falls into a pit or hopper, where it is loaded into trailers via conveyor or blower. The material can either be spread or sold locally, or removed by EnviroGro. The product has uses in numerous markets including soil conditioner for any soil, organic farming, and as a component in soil mixes for professional growers and in the retail lawn and garden market. EnviroGro's concept and approach can accommodate any size of operation. Smaller farms, conveniently located, can operate a single until in a cooperative manner as long as they can economically transport the manure.
