Abstract: A filling system for a vacuum insulated structure includes a powder processor configured to load an internal cavity of the vacuum insulated structure with a heated and at least partially degassed vacuum insulation material. The powder processor includes a hopper with inner and outer hopper walls. The inner hopper wall includes an air permeable surface. A heater is positioned in a space defined between the inner and outer hopper walls. A feed screw is positioned along an inside edge of the inner hopper wall. A vacuum port is positioned on the outer hopper wall. An aperture exit is positioned at a bottom of the hopper. At least one evacuator is coupled to the vacuum port of the powder processor. The at least one evacuator is configured to couple to a vacuum port of the vacuum insulated structure and apply a vacuum to the internal cavity of the vacuum insulated structure.

Abstract: A filling system for a vacuum insulated structure is provided having a powder processor including a hopper having an inner hopper wall and an outer hopper wall. The filling system also includes a vacuum insulated structure having a liner positioned inside a wrapper, a trim breaker coupling an outer liner edge and an outer wrapper edge to form a shell defining an internal cavity with at least one gas permeable feature positioned in the internal cavity configured to help apply a vacuum. A loading port is positioned on a surface of the shell. The powder processor loads the shell with a heated and at least partially degassed vacuum insulation material through the loading port while a vacuum is applied to the shell through the at least one gas permeable feature.
