GALLERY: Dehydrators/Digesters

The fully-automated BioGreen360 organic food waste digester operates using a continuous-feed loading system and processes 1,500 lb. of food waste in 24 hr. The machine accelerates the decomposition process using long-lasting, proprietary microorganisms. A microbial process liquefies food waste then fast-acting patented microwave technology rapidly heats and evaporates the liquid. The end product is an immediately compostable organic matter that is 10% its original weight and 100% sterile. The system doesn’t require water intake and doesn’t discharge water; there’s no need for drain access. Operating the unit requires an electrical hook up and venting. Measuring about 56-in.W x 543/4-in.D x 791/2-in.H, the system is clean, quiet and self-contained.

The BioHiTech Eco-Safe Digester comes in three models, available to digest 400-2,500 lb. of virtually any kind of food waste—vegetables, fruits, meat, fish, poultry, grains, coffee grounds, egg shells and dairy products—within 24 hr. You can continuously add food waste throughout the day. The system uses a proprietary blend of microorganisms while agitation and water help digest the food waste into a grey-water effluent that drains into the conventional sewer system. The digester also weighs each increment of waste during the digestion process, providing data for waste-stream analysis. The Eco-Safe 4, the smallest unit, measures 453/4-in.W x 351/2-in.D x 50-in.H while the larger Eco-Safe 12 tallies 69¼-in.W x 44¼-in.D x 55 ¼-in.H.

Champion’s Phoenix Dehydrator processes organics, including produce, cut flowers, meat, fat trimmings, fish, paper napkins, coffee grounds, spoiled milk and deli products, as well as some soft plastics, reducing waste by up to 90%. The dried remnants are produced as a sterile biomass. The company’s proprietary technology features accelerated dehydration for a shorter processing time; the dehydrator can process up to 2 batches of food waste a day. (A moisture sensor illuminates LED lights to let you know when the cycle is finished.) Models are available in a range of capacities from 125-2,400 lb. The larger model PHX-1400AL measures 93-in.W x 63-in.D x 91-in.H and processes 1,400 lb. in 18-23 hr. The Phoenix dehydrator can stand alone or be part of Champion’s Trisys waste-management system.

Each unit is constructed of 304 stainless and the decomposition chamber uses heat and mechanical agitation to break down waste. The system is capable of reducing compostable waste weight and volume by 83%-93% depending on the waste input. Units come in sizes to process from 66-6,600 lb. per cycle. The chamber has an oil jacket with substantial insulation and well-sealed inlet and outlet doors to minimize energy consumption. The system is equipped with an odor management device to control odors associated with decomposition. The utility requirements are an electrical source and a condensate line; no venting or fresh water connections are required. The decomposing chamber is capable of producing 180°F during the processing to ensure that the end product is essentially odor free.

EnviroPure’s EPW Systems are self-contained, continual-feed organic-food-waste elimination systems that convert food waste into water. The technology uses a combination of mechanical processing, heat, oxygen and all-natural additives (EPW-BioMix) to accelerate the natural aerobic decomposition process. Organic waste quickly reduces to a grey-water effluent that can be safely disposed of into existing sewer systems. The EPW Systems handle virtually any kind of food waste, from vegetables and fruits to dairy products and bones. Depending on the model, the GTSeries processes 240-3,000 lb. (750-9,000 meals) per day and consumes between 2-19 gal. of water per hr. The smallest unit measures 48-in.W x 78-in.D x 80-in.H while the largest unit is 100-in.W x 130-in.D x 110-in.H.

Hungry Giant systems heat and kill all bacteria and pathogens reducing food waste weight and volume by up to 93% without using water. Hungry Giant Australian engineers have developed a proprietary turbo-charged condensing/cooling system that will dehydrate food waste 20%-25% faster than its competitors saving significant energy costs over the 10-plus-year life span, according to the company. This liquid coolant system pulls water out of the food waste in the form of steam and then converts that steam into sterile condensate much faster than air-cooled-only dehydrators. The company offers 7 models that process from 220-2,400 lb./day. Larger units include hydraulic garbage tote lifter. Prices list from $25,900 to $150,000.

Managed by InSinkErator, Grind2Energy food waste recycling systems comprise a three-step process—grind, transport and transform—to turn waste into renewable energy. First, the system grinds food waste into a slurry. High-density shredding elements grind as fast as you can feed it; dry-grind technology minimizes the amount of water used. A sealed, enclosed tank at your facility stores the slurry. Once fluid levels in the tank reach a certain point, a sensor notifies a transportation team, who hauls the material in a truck to a local anaerobic digestion facility. Here, captured emitted gases (methane) convert into electricity or natural gas and the remaining bio-solids become fertilizer. Grind2Energy makes sense for facilities that produce at least 1 ton of food waste per week. The system requires a 3-phase power supply, water hookup and a tank-holding area.

LFC models process anywhere from 110-4,000 lb. of food waste in 24 hr. Water injects into the machine to maintain equilibrium for the microorganisms, to rapidly decompose the food waste and to then flush the resulting grey water safely into the sewer system. The machine’s rotating arm slowly churns waste to enhance the decomposing function; a proprietary mixture of microbes and enzymes accelerates the digestion. The continuous process enables you to add food at any time; the machine doesn’t need to be emptied. The LFC securely sends data through an Ethernet port to a cloud server maintained by Power Knot. Studying data (waste amounts, door openings, etc.) helps you better manage your facility’s waste. Machines range in size from 34-in.W x 27-in.D x 40-in.H to 102-in.W x 56-in.D x 69-in.H.

The Somat DH-100 dehydrator handles food waste and compostable disposables for medium- to large-scale facilities. The machine processes 110-220 lb. in 12-18 hr. through a multistage indirect heat and dry dehydration processes; no enzymes or additives required. An added bonus: dryness-sensing technology ensures proper processing time regardless of the batch size. Easy to install and maintain, the standalone machine doesn’t require a fresh water connection. Paddles macerate the food waste heated by the unit’s decomposing chamber to kill any bacteria and reduce matter by 83%-93%. A new cold weather package allows the dehydration process to occur at temperatures down to 15°F. The DH-100 footprint measures 45-in.W x 371/2-in.D x 441/2-in.H.

The ORCA organic food processing system offers a sustainable food waste disposal solution that allows customers to dispose of organics at the source. The ORCA uses an aerobic digestion process that converts food waste into an effluent safe for discharge into the municipal wastewater system where high-value renewable fuels and natural fertilizers can be economically produced and recovered. The unit accelerates the breakdown of food waste through a combination of proprietary microorganism solution and Bio Chips, oxygen and water. The ORCA can divert up to 600, 1,200 or 2,400 lb. per day, depending on food waste composition and model size. Model dimensions range between 48-in.W x 34-in.D x 49-in.H and 115-in.W x 34-in.D x 49-in.H. The ORCA is service based with no capital outlay.
