Abstract
A system and method are provided for a food loading station having a disposer that grinds food waste that is located at a facility that processes food waste. A storage tank receives a slurry of food waste and water from the disposer for storage until the slurry is collected for transportation to an anaerobic digestion facility. An agitator is installed in the storage tank for mixing the slurry stored in the storage tank prior to collection for transportation to the anaerobic digestion facility. A discharge outlet is installed on the storage tank for connection to a discharge hose of a collection truck. The discharge outlet has an air admittance valve for admitting ambient air into the discharge hose while the slurry is sucked out of the storage tank through the discharge hose and into the collection truck.
Claims5
A system comprising:
- a food loading station located at a facility that processes food waste, the food loading station having a grinder that grinds food waste into a slurry of food waste and water;
- a storage tank that receives the slurry of food waste and water from the grinder for storage until the slurry is collected for transportation to an anaerobic digestion facility;
- and
- a discharge outlet installed on the storage tank configured to connect to a discharge hose of a collection truck, the discharge outlet having an air admittance valve configured to admit ambient air into the discharge hose while the slurry is sucked out of the storage tank through the discharge hose and into the collection truck.
