A refrigerator comprises a vacuum source and a food storage compartment including a drawer unit having a storage space. The food storage compartment is operable between a substantially air-tight retracted position and an open extended position. A vacuum source is in communication with the storage space of the drawer unit and is operable to reduce air pressure inside the drawer unit during an evacuation event. A sealing unit includes a base connected to the drawer unit. A sealing bracket is hingedly-connected to the base and operable between a raised position and a lowered position, the sealing bracket adapted to abut the base when in the lowered position. A heat sealing bar is disposed on one of the base and the sealing bracket. A control system is operable to activate the vacuum source and initiate the evacuation event when the drawer unit is in the air-tight retracted position.

1. A refrigerator comprising: a food storage compartment including a drawer unit with a storage space and an adjustable perforated platform, the drawer unit being operable between a substantially air-tight retracted position and an open extended position, wherein the operable movement of the adjustable perforated platform is independent of the operable movement of the drawer unit between the substantially air-tight retracted position and the open extended position;a vacuum source in communication with the storage space of the drawer unit and operable to reduce air pressure inside the drawer unit during an evacuation event when the drawer unit is in the air-tight retracted position;a heat sealing unit disposed within the drawer unit adapted to seal a flexible bag;a hard removable container disposed inside the storage space and including a valve that opens to allow depressurization of the hard removable container during the evacuation event; anda control system operable to activate the vacuum source and initiate the evacuation event when the drawer unit has been placed in the air-tight retracted position, and operable to activate the heat sealing unit at least when the drawer unit has been placed in the air-tight retracted position. 2. The refrigerator of claim 1, wherein the valve is a one-way valve that allows depressurization of the hard removable container during the evacuation event and maintains a depressurized condition in the hard removable container when the drawer unit is in the open extended position. 3. The refrigerator of claim 1, wherein the food storage compartment includes a front wall having a portion that allows at least partial visibility into the drawer unit when the drawer unit is in the air-tight retracted position. 4. The refrigerator of claim 1, wherein the perforated platform is vertically adjustable within the drawer unit. 5. The refrigerator of claim 4, wherein the vertically adjustable platform includes at least one aperture therein. 6. The refrigerator of claim 1, wherein the drawer unit has first and second side walls and wherein at least one rear support extends between the first and second side walls. 7. A compartment for a refrigerator comprising: a drawer unit having a storage space and operable between a closed retracted position and an open extended position;a vacuum source in communication with the drawer unit;a control system operable to activate the vacuum source and initiate an evacuation event;a vertically adjustable platform disposed in the drawer unit, wherein the movement of the vertically adjustable platform is independent of the operable movement of the drawer unit between the closed retracted position and the open extended position; anda hard removable container disposed inside the storage space and including a valve that opens to allow depressurization of the hard removable container during the evacuation event. 8. The compartment of claim 7, wherein the food storage compartment includes a front wall having a portion that allows at least partial visibility into the drawer unit when the drawer unit is in the closed retracted position. 9. The compartment of claim 7, wherein the vertically adjustable platform includes at least one aperture defined within a bottom wall of vertically adjustable perforated platform. 10. The compartment of claim 7, wherein the drawer unit has first and second side walls and wherein at least one rear support extends between the first and second side walls. 11. The compartment of claim 7, further comprising: a sealing unit adapted to seal a flexible bag. 12. The compartment of claim 11, wherein the evacuation event occurs only in the sealing unit. 13. A method of sealing a storage container in a refrigerator, the method comprising: providing a drawer unit in the refrigerator having a storage space and operable between a closed retracted position and an open extended position, wherein the drawer unit includes a vertically adjustable perforated platform, and wherein the movement of the vertically adjustable perforated platform is independent from the operable movement of the drawer unit between the closed retracted position and the open extended position;inserting a hard container into the drawer unit;providing a valve on the hard container;actuating a vacuum source in communication with the storage space of the drawer unit to reduce air pressure within the hard container; andremoving the hard container from the drawer unit. 14. The method of claim 13, wherein the step of actuating a vacuum source in communication with the storage space further comprises: reducing the air pressure in the hard container and the entire storage space. 15. The method of claim 13, wherein the vertical adjustable perforated platform includes at least one aperture defined within a bottom wall of the vertically adjustable perforated platform, such that a plurality of hard containers can be depressurized simultaneously.
