A method for adding a vacuum insulation material into a vacuum insulated refrigerator structure, the method comprising: providing a powder processor comprising: a hopper having an inner hopper wall and an outer hopper wall, wherein the inner hopper wall includes an air permeable surface; a heater positioned in a space defined between the inner and outer hopper walls; a feed screw positioned along an inside edge of the inner hopper wall; an evacuator coupled to a vacuum port positioned in the outer hopper wall; and an aperture exit positioned at a bottom of the hopper; loading a vacuum insulation material to the hopper; mixing the vacuum insulation material with the feed screw; applying heat and a first vacuum to the vacuum insulation material to form a dry and degassed vacuum insulation material; applying a second vacuum to a vacuum insulated refrigerator structure using a gas permeable feature, the vacuum insulated refrigerator structure having one or more gas permeable features positioned and coupled along the liner and wrapper, the liner and wrapper defining the internal cavity; loading the dry and degassed vacuum insulation material into the vacuum insulated refrigerator structure through the aperture exit and a loading port; removing the powder processor and continuing to apply the second vacuum to the loading port of the vacuum insulated refrigerator structure; and sealing the loading port to form the vacuum insulated refrigerator structure. providing a powder processor comprising: a hopper having an inner hopper wall and an outer hopper wall, wherein the inner hopper wall includes an air permeable surface; a heater positioned in a space defined between the inner and outer hopper walls; a feed screw positioned along an inside edge of the inner hopper wall; an evacuator coupled to a vacuum port positioned in the outer hopper wall; and an aperture exit positioned at a bottom of the hopper; a hopper having an inner hopper wall and an outer hopper wall, wherein the inner hopper wall includes an air permeable surface; a heater positioned in a space defined between the inner and outer hopper walls; a feed screw positioned along an inside edge of the inner hopper wall; an evacuator coupled to a vacuum port positioned in the outer hopper wall; and an aperture exit positioned at a bottom of the hopper; loading a vacuum insulation material to the hopper; mixing the vacuum insulation material with the feed screw; applying heat and a first vacuum to the vacuum insulation material to form a dry and degassed vacuum insulation material; applying a second vacuum to a vacuum insulated refrigerator structure using a gas permeable feature, the vacuum insulated refrigerator structure having one or more gas permeable features positioned and coupled along the liner and wrapper, the liner and wrapper defining the internal cavity; loading the dry and degassed vacuum insulation material into the vacuum insulated refrigerator structure through the aperture exit and a loading port; removing the powder processor and continuing to apply the second vacuum to the loading port of the vacuum insulated refrigerator structure; and sealing the loading port to form the vacuum insulated refrigerator structure.
