Evac’s vacuum food waste collection system conveys food waste reliably, even when it contains large amounts of bulky or starchy substances such as pasta, rice, bread, or potatoes. The system is fully automatic and can be controlled from the engine control room. A single feeding station can process 700 kg of food waste an hour, which means the system can easily handle all the wet biowaste produced in the galley of a small or mid-sized vessel. Because the system is based on vacuum technology, it is possible to use piping with a small diameter (typically 50 or 60.3 mm).
Evac can also provide custom food waste collection and treatment systems for larger vessels such as cruise ships.
The system is vacuum operated and consists of three main units: macerator or shredder macerator feeding stations, a vacuum unit, and a food waste tank. Food waste is macerated in the galley area. A small amount of water is added to create slurry, which is then collected in the food waste tank. The slurry is mixed using a discharge or recycling pump, and then pumped overboard or to a collecting facility on shore, or further treated in a dewatering process.
Evac infeed stations for food waste are manufactured from durable stainless steel and delivered complete with all necessary fittings. The hopper is connected to the vacuum collecting system and welded to the tabletop, which is equipped with a drain sieve and overflow to limit the amount of free-flowing water in the collection system.
The hopper has a volume of approximately 30 l/7.9 gal and an upper diameter of 500 mm, and it is fitted with cleaning nozzles. The piping for collecting the food waste from the feeding stations is DN 150. The infeed station unit is connected to the vacuum pipeline using a DN 125 quick-clamp connection and can be isolated for maintenance.
We offer fully automated macerator feeding stations ( Evac MFS) and shredder macerator feeding stations (Evac SMFS). The Evac SMFS is almost identical to Evac MFS, but with an extra-coarse grinder installed on top of the unit for chopping food waste into small fragments that can be fed into the macerator.
