Evac food waste management system
Evac food waste management systemFood waste collection and treatment
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 for storage to wait for further processing.

Evac vacuum creation unit
Vacuum is normally generated by a vacuum pump unit, measured by a sensor transmitter in the cyclone, and controlled by an automation logic system. Vacuum is created in the pipeline prior to the vacuum conveying, when a discharge is requested at a feeding station. When a vacuum of 250 mbars is reached, the feeding station opens a gate valve and the food waste is conveyed to the vacuum cyclone. The food waste remains in the cyclone while the air is ejected out the top.
Systems are installed as two line systems, each featuring a vacuum station including a cyclone and vacuum pump units. The two vacuum stations are cross-connected.
Evac food waste tank
Our compact, skid-mounted food waste tanks are made from corrosion-resistant material and are available in four sizes. The tanks are fitted with a mixer to prevent sedimentation and a level-sensor system to prevent slurry overflow. Discharge is remote controlled via the main automation system.
