1,2,3 Professor, Dept. Of Mechanical Engineering, D. Y. Patil College Of Engineering, Akurdi, Pune, India Abstract — A vacuum storage system in a refrigerator includes a drawer unit removable received in housing. The vacuum storage system may be utilized in a storage configuration or in a vacuum sealing configuration to remove air from food preservation compartment having one way evacuation valves. A switch on a control interface actuates a vacuum source and a front wall of the drawer unit seals against the cabinet. Air is drawn from the storage space via a hose in communication with the vacuum source and air pressure within the storage space is reduced below atmospheric pressure. At a predetermined pressure, a control deactivates the vacuum source. Later while opening the drawer an equalizing valve is opened to return the storage space to atmospheric pressure.
